Hydraulic solenoid valve refers to a component used to control liquid pressure, flow and direction in hydraulic transmission. Its application in our modern life is more extensive. Hydraulic solenoid valves are an automated basic element used to control fluids and are actuators. Hydraulic solenoid valves are used to control the direction of hydraulic flow. Factory mechanical devices are generally controlled by hydraulic cylinders, so hydraulic solenoid valves are used. What is the working principle of the hydraulic solenoid valve? What is the meaning of the hydraulic solenoid valve model ? If you want to know more about what the hydraulic solenoid valve model is, let me know about it!
Hydraulic solenoid valve model meaning
About the hydraulic solenoid valve model, different manufacturers of different models of the layout is different, here a small series to give an example of the meaning of the hydraulic solenoid valve model, such as 34BYM-L20H-T, where 34 represents the 3 4 pass, B is the exchange Type, Y is hydraulic, M is a spool valve function, L is a threaded connection, 20 is a nominal diameter, H is a nominal pressure, H is a high pressure 31.5MPA, and T is a spring centered designator. For more specific model meanings, consult the relevant manufacturers.
Hydraulic solenoid valve features
1. The leakage of the hydraulic solenoid valve must be blocked, the internal leakage is easy to control, and the safety is safe.
2. The hydraulic solenoid valve system is simple, easy to maintain and inexpensive.
3, the hydraulic solenoid valve moves quickly, the power is tiny, the appearance is light and exquisite.
Hydraulic solenoid valve classification
A hydraulic solenoid valve is a component used to control fluid pressure, flow, and direction in a hydraulic drive. In the hydraulic solenoid valve, the control pressure is called a pressure control valve, and the control flow is called a flow control valve, and the control of the on, off, and flow direction is called a directional control valve. There are new classifications under these control valves. Let's take a look at other classifications.
1. The pressure control valve can be divided into relief valve, pressure reducing valve and sequence valve according to the purpose.
(1) Relief valve: It can control the hydraulic system to maintain a constant state when reaching the set pressure. The relief valve used for overload protection is called a safety valve. When the system fails and the pressure rises to a limit value that may cause damage, the valve port will open an overflow to ensure the safety of the system.
(2) Pressure reducing valve: It can control the branch circuit to obtain a stable pressure lower than the main circuit oil pressure. Relief valve according to its control of the pressure function is different, can be divided into fixed value pressure reducing valve, fixed pressure reducing valve and constant pressure reducing valve.
(3) Sequence valve: After one actuator is actuated, the other actuators are operated in sequence.
2. The flow control valve regulates the flow by using the orifice area between the regulating spool and the valve body and the local resistance generated by it, so as to control the movement speed of the actuator. Flow control valves are divided into five types according to their use.
(1) Throttle valve: After the throttle orifice area is set, the throttle valve can make the movement speed of the actuator that does not greatly change the load pressure and the motion uniformity requirements are basically stable.
(2) Speed control valve: It can maintain the differential pressure at the inlet and outlet of the throttle valve when the load pressure changes.
(3) Diverter valve: A proportional diverter valve is a proportional diverter valve or a synchronous valve in which both actuators of the same oil source can obtain equal flow regardless of the load.
(4) Collector valve: It distributes the flow into the collector valve in proportion to the function of the diverter valve.
(5) Shunt manifold: It has the function of a diverter valve and a manifold valve.
3. Directional control valves are divided into one-way valves and reversing valves according to their purpose.
(1) Check valve: Only one-way connection of the fluid in the pipe is allowed, and the reverse is cut off.
(2) Reversing valve: changing the on-off relationship between different pipelines, according to the working position of the valve core in the valve body is divided into two, three, etc.; according to the number of channels controlled by two, three, four Tong, five links, etc.; according to the spool drive manual, mobile, electric, hydraulic and so on.
Hydraulic solenoid valve working principle
There are sealed chambers in the hydraulic solenoid valve. There are through holes in different positions. Each hole is connected to a different oil pipe. The piston in the middle of the cavity is two electromagnets on both sides. Which side of the magnet coil energizes the valve body and is attracted to it. Which side, by controlling the movement of the valve body to open or close different oil discharge holes, and the oil inlet hole is normally open, the hydraulic oil will enter a different oil discharge pipe, and then push the pressure of the oil to push the piston of the oil cylinder, the piston It also drives the piston rod. The piston rod drives the mechanical device so that the mechanical motion is controlled by controlling the on-off of the electromagnet.
Editor's summary: The above is the meaning of the hydraulic solenoid valve model, the introduction of the working principle of the hydraulic solenoid valve, hoping to help meet the needs of friends!
