Double acting cylinder (with magnetic switch)

image



How to use: Adjust the speed of the cylinder by adjusting the throttle valve. The left throttle valve is retracted and the right throttle valve is extended. The magnetic switch (near-vision switch) is used to detect the position of the cylinder. When the cylinder is retracted, the magnetic switch on the right is turned on, otherwise the left is turned on. When the magnetic switch is used, the power supply cannot be directly applied to both ends, and the load must be connected in series (the + end is made by the red small lamp).


Single acting cylinder

How to use: Adjust the speed of the cylinder by adjusting the throttle valve. When the gas in the throttle valve passes, the cylinder will extend. Otherwise, the cylinder will retract when there is no gas (automatically reset by the spring).


Two-position five-way single electronically controlled solenoid valve

The three direct heads are connected to the end of the gas pipe, respectively, the P inlet end, the A: A position, and the B: B position. When P has gas, the A position is out of gas (ie, the initial position of the solenoid valve), when the solenoid valve coil is energized (the DC24V small lamp is positive), the solenoid valve is reversed, and the B position is out. When the solenoid valve coil is de-energized, it is restored to the initial position by the spring.

The three direct heads are connected to the end of the gas pipe, respectively, the P inlet end, the A: A position, and the B: B position. When there is gas in the P port, the gas is still out at the previous gas outlet (that is, the position where the last solenoid valve is energized), when the solenoid valve coil 1Y1 is energized (the DC24V small lamp is positive), the solenoid valve is reversed, A mouth is out. When the solenoid valve coil 1Y2 is energized (the DC24V small lamp is positive), the solenoid valve is reversed, and the B port is exhausted. This position is retained after the solenoid is de-energized.

The three direct heads are connected to the end of the gas pipe, respectively, the P inlet end, the A: A position, and the B: B position. When the P port has gas and the solenoid valve coil is not energized, it is reset by the action of the springs on both sides, and no air is released from the A and B ports, and the valve is kept at the neutral position. When the solenoid valve coil 1Y1 is energized (the DC24V small lamp is positive), the solenoid valve is reversed, and the A port is vented. When the solenoid valve coil 1Y2 is energized (the DC24V small lamp is positive), the solenoid valve is reversed, and the B port is exhausted. After the solenoid valve coil is de-energized, the valve body is automatically reset under the action of the springs on both sides, and no air is released from the A and B ports, and the valve is kept in the neutral state.


Electric signal limit switch

The component is used to detect the position of the cylinder and is placed in the retracted and extended position of the cylinder to make it contact the cylinder probe for action. When the white roller end bounces, the COM terminal is connected to the NC and NO is disconnected. When the white roller end is pressed by the cylinder probe, COM and NO are turned on, and the NC is disconnected. The two electrical signal travel switches are a pair for detecting the left and right seats of the cylinder.


Capacitive sensor


image

Sensor wiring method: red ferrule is connected to DC24V, black ferrule is connected to DC0V, and blue ferrule is output. When the sensor senses the signal, the point outputs the signal (the signal level depends on the sensor type, the NPN type is the output DC0V, and the PNP type outputs the DC24V). Pay attention to the correctness of the wiring during use to prevent damage to the components, especially the short circuit at the output is the most serious.


Capacitive sensors, also known as proximity switches, sense any object close to it. The detection range is generally between 0.8-1 CM (adjustable).

Sensor wiring method: red ferrule is connected to DC24V, black ferrule is connected to DC0V, and blue ferrule is output. When the sensor senses the signal, the point outputs the signal (the signal level depends on the sensor type, the NPN type is the output DC0V, and the PNP type outputs the DC24V). Pay attention to the correctness of the wiring during use to prevent damage to the components, especially the short circuit at the output is the most serious.


Photoelectric sensors detect objects that reflect enough light to sense them. The detection range is generally around 6CM. Due to this characteristic, we can use the intensity of the reflection of different colors of objects to adjust the distance, and indirectly can detect the color.


Inductive sensor

Sensor wiring method: red ferrule is connected to DC24V, black ferrule is connected to DC0V, and blue ferrule is output. When the sensor senses the signal, the point outputs the signal (the signal level depends on the sensor type, the NPN type is the output DC0V, and the PNP type outputs the DC24V). Pay attention to the correctness of the wiring during use to prevent damage to the components, especially the short circuit at the output is the most serious.


Inductive sensors are used to detect metal species, and the detection range is generally around 1CM. Relative to the above two sensors, it is stable and will not be disturbed by some other items, resulting in a false signal because it has a short detection distance and is only effective for metal objects.


Gas-electric converter


image

As the name implies, the component converts the pneumatic signal into an electrical signal, and the internal opening of the component becomes a normally closed contact through the air supply end intake. It is typically stringed in the circuit to act as a control signal.


Emergency stop switch


image

The normally closed contact of the component is inserted into the main circuit (power-on circuit). When an error occurs in the improper operation of the circuit, the red button is pressed to stop the operation of the entire circuit. Rotate in the direction marked by the white arrow on the button surface, and the emergency stop is released, and the power-on start operation can be continued.


Manual reversing valve

The L-type joint is connected to the gas pipe mouth. When the P port is supplied with gas, the intake and outlet of the A and B ports are controlled by pulling the manual switch. When the circuit is switched, exhaust is performed through the exhaust port.


Check valve

When the air inlet P1 has air, the air outlet P2 is exhausted. On the contrary, when the air outlet P2 is ventilated, the air inlet P1 has no air, which is called a one-way.


One-way throttle

When the air inlet P1 is ventilated, the adjustment knob can control the air outlet flow of the P2 port.


Pneumatic display


image


The P1 and P2 ports of the component are respectively connected into the pneumatic circuit, and it can be detected whether the circuit is working normally and whether the vents are in and out. When there is gas in the loop, the indicator light is red, otherwise it is blue.


Pressure gauge

By connecting the component to a node in the loop, the pressure value at that point can be detected, which is mainly used to monitor the node air pressure.


Pressure regulating valve


image

image


By connecting the component to a loop, the air pressure at that loop can be adjusted. P1 is the air inlet and P2 is the air outlet. If the P1 and P2 ports of the component are reversed, an internal sound will be emitted. Pull up the black knob and rotate it in the direction of the arrow to adjust the air outlet pressure. In principle, the export pressure should be less than the import pressure.


Air control delay valve

image


The above symbols are time-delay normally open, and the symbols below are time-delay normally closed.


The components we provide are available in two ways, but only one of them can be used at a time. When the air inlet P4 is normally open, the control port P1 is ventilated, and after a delay of N seconds (by the adjustment knob), the P2 port is vented. When the air inlet P3 is normally closed, the control port P1 is ventilated, and the P2 port first has a gas output, and after a delay of N seconds (by the adjustment knob), the P2 port is shut off.


Two-position three-way button type directional control valve


image


When the air inlet P1 is ventilated, the push button switch is pressed, and the air outlet P2 is ventilated. Usually the component is used as a start button string in the loop.


Two-position five-way single air control reversing valve


image


When the air inlet P is ventilated, when there is no gas entering the control port P1, the air outlet A has a gas output; when the control port P1 is ventilated, the air outlet B has a gas output, and the air outlet A is disconnected. When the control port P1 turns off the gas again, the valve returns to the initial position by means of its own spring.


Two-position five-way dual air control reversing valve


image


When the air inlet P is ventilated, no air is passed through the air outlets A and B, and the air exits from the previous state A or B is still maintained. When the control port P1 is ventilated, the air outlet B has a gas output; otherwise, when the control port P2 is ventilated, the air outlet A has a gas output.


Three-position five-way dual air control reversing valve


image


When the air inlet P is ventilated and the control ports P1, P2 are free of air, the air outlets A, B have no output and the valve body remains at the neutral position. When the control port P1 is ventilated, the air outlet B has a gas output; otherwise, when the control port P2 is ventilated, the air outlet A has a gas output.


Two-position three-way roller lever type reversing valve


image

image


When the intake port P is ventilated and the roller is depressed by the cylinder probe, the air outlet A has a gas output. Otherwise, the A port has no gas output. In the direction of the roller, the valve is divided into two pairs, that is, a pair, for detecting the cylinder position.

When the intake port P is ventilated and the roller is depressed by the cylinder probe, the air outlet A has a gas output. Otherwise, the A port has no gas output. In the direction of the roller, the valve is divided into two pairs, that is, a pair, for detecting the cylinder position. When the cylinder probe is in the process of retracting, the roller part of the valve also has the function of automatically giving way, avoiding mutual friction between the probe and the roller, thereby greatly reducing the phenomenon that the entire circuit cannot work, which is commonly known as " Idler".


Quick exhaust valve

When the air inlet P is ventilated, the air outlet A has a gas output; when the air inlet P has no air, the gas at the air outlet A is quickly discharged to the atmosphere through the muffler of the R port.


Or valve (baud valve)
