What Kind Of Solenoid Valve Does Cutting Machine Manufacturer Introduce?

- Sep 16, 2020-

The solenoid valve is an automatic basic element used to control the liquid of the cutting machine. It belongs to the actuator, used to adjust the direction, flow, speed and other parameters of the medium in the industrial control cutting machine system. The solenoid valve can cooperate with different circuits to achieve the ideal control effect and ensure the accuracy and flexibility of the control tool. There are many types of solenoid valves. Different solenoid valves have different control functions on different positions of the cutting machine system.

One-way valve

1. Throttle valve

2. Directional control valve;

3. Overflow valve

What is the function of the throttle valve used in the cutting machine?

The throttle valve used in the cutting machine controls the flow of fluid by changing the throttle section or throttle length. The parallel connection of the throttle valve and the one-way valve can be combined into a one-way throttle valve. Throttle valves and one-way throttle valves are simple flow control valves. In the hydraulic system of the quantitative pump of the cutting machine, the throttle valve and the safety valve cooperate with each other to form three types of throttle speed control systems: the air intake throttle speed control system, the return throttle speed control system and the bypass throttle speed control system. The throttle valve has no flow negative feedback function and cannot compensate for the unstable speed caused by load changes. They are usually only used when load changes are small or speed stability requirements are not high.

What is the function of the safety valve used in the cutting machine manufacturer? The pressure relief valve is a hydraulic control valve, which mainly plays the role of setting pressure overflow, stability, system unloading and safety protection in the hydraulic equipment of the cutting machine. When assembling or using the safety valve, due to the damage of the O-ring and the combined sealing ring, or the loosening of the mounting screws and pipe joints, it may cause bad leakage. If the poppet valve or the main valve core is worn too much, or the sealing surface is in poor contact, it will also cause excessive internal leakage and even affect normal operation. What is the function of the one-way valve of the cutting machine? One-way valve, also known as one-way valve, is used to prevent reverse flow of oil in the hydraulic system of cutting machine tools. There are two types of check valves: straight-through valves and right-angle valves. The straight one-way valve is installed on the pipeline through a threaded connection. Right-angle check valves have threaded connection, plate connection and flange connection.

The hydraulic control check valve, also known as the lock valve and the pressure maintaining valve, is the same as the check valve to prevent the reverse flow of oil. However, when the oil flow in the hydraulic circuit needs to flow in the opposite direction, the oil pressure can be controlled and the one-way valve can be opened to make the oil flow flow in both directions. The hydraulically controlled check valve adopts a tapered valve core with good sealing performance. When the oil pipeline needs to be closed, the valve can be used as a one-way locking device to maintain pressure. There are two ways to control oil leakage through hydraulic check valves: internal and external. The internal leakage type can be used in the oil pipeline with no back pressure at the oil flow reverse outlet, otherwise the external leakage type must be used to reduce the control oil pressure.
