Everyone knows that pneumatic components are widely used. At present, my country's pneumatic components and hydraulic components have gradually become standardized, standardized and serialized. In recent years, pneumatic technology has been widely used in machinery, chemical, electronics, electrical, textile, food, packaging, printing, light industry, automotive and other industries, especially in various automated consumer equipment and consumer lines, and has greatly improved The consumption efficiency and production quality of the manufacturing industry have attracted the attention of industries all over the world, and the pneumatic industry has become one of the fastest-growing industries in industrial countries.

In the last article, we introduced the one-way throttle valve. In fact, the throttle valve is also a pneumatic component. In addition to this, what are our common pneumatic component products? Next, I will introduce you to the top ten commonly used pneumatic components. .

1. One-way throttle valve: When the air intake port P1 is ventilated, the adjustment rotation can control the air flow rate of the P2 port.

2. Manual reversing valve: The L-type connector is connected to the air pipe port. When the P port is supplied with air, the manual switch is moved to control the air intake and the air output of the A and B ports. When the circuit is switched, the exhaust is exhausted through the exhaust port.

3. Pressure gauge: Connect this element to a certain node in the loop, and the air pressure value at that point can be detected, which is mainly used to monitor the node air pressure.

4. Pressure regulating valve: The gas pressure regulating valve is a lever type differential pressure feedback control pressure regulating. The gas in the cylinder is liquid, and the pressure is too high. It must be decompressed to be suitable for burning in the stove. The gas pressure regulator is broken and must be replaced. Consequence 1, no breath; Consequence 2, no decompression. If the pressure is not reduced, it is easy to cause the hose to fall off, and the gas leaks, and the consequences are unimaginable. Decompression principle: The high-pressure medium is punched into a relatively large cavity through a small hole to achieve decompression. In fact, the decompression is achieved by intercepting the flow. One side of the diaphragm or piston is the outlet cavity, and the other side is artificial pressure, and the valve stem that controls the size of the orifice is connected to the diaphragm (piston).

5. Photoelectric sensor: A photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect means that when light is irradiated on some material, the electrons of the material absorb the energy of the photon and the corresponding electric effect occurs.

6. Single-acting cylinder: one of the common cylinders. Divided into spring reset and external force reset. Pneumatic actuators are mainly divided into linear reciprocating type, swing type and continuous rotary type.

7. Double-acting cylinder: Air is supplied alternately from both sides of the piston to output force in one or two directions.

8. Capacitance sensor: Capacitance sensor refers to a sensor that converts the change of the measured (such as size, pressure, etc.) into a change in capacitance. In fact, it itself (or the object under test) is a variable capacitor.

Capacitive sensor
9. Pneumatic-electric converter: The pneumatic-electric converter converts the dimensional change measured by the pneumatic measuring head into a continuously changing voltage signal. It is used in conjunction with a special electric box or industrial control computer to realize non-contact automatic control. Comprehensive measurement.

Gas-to-electric converter
10. Emergency stop switch: The emergency stop switch is a kind of master control electrical appliance. When the machine is in a dangerous state, the power supply is cut off by the emergency stop switch to stop the operation of the equipment, so as to protect the safety of people and equipment.
