Description
TECHNICAL FIELD
[0001] The utility model relates to a pilot type electromagnetic valve and belongs to the technical field of electromagnetic valve equipment. BACKGROUND
[0002] As a valve for controlling the flow of fluid, the electromagnetic valve has a valve core that opens and closes the flow path, and a movable element called a plunger that is driven by a solenoid. The valve core is driven by the plunger, and the valve core is opened and closed to control the flow path by the action. If the electromagnetic valve is classified according to the driving method of the valve core, it can be divided into direct-acting electromagnetic valves and pilot-type electromagnetic valves. The type in which the valve core of the main valve is directly connected to the driving plunger is called "direct-acting", and the type in which the valve core of the main valve is driven by the pressure of the fluid through a diaphragm or a piston and controlled is called "pilot type".
[0003] Publication No. CN220320439U discloses a pilot-type electromagnetic valve, which relates to the field of electromagnetic valves.

The top of the valve body is provided with a rotating assembly, and the rotating assembly includes a first cover and a second cover installed on both sides of the top of the valve body through hinges. When the solenoid needs to be repaired or replaced, the user can rotate the turntable, which will drive the limiting plate to rotate, so that the limiting plate can be turned out of the limiting groove. After the limiting plate is turned out, the first cover and the second cover are no longer fixed, and then the user can rotate the first cover and the second cover to open them.

This way can quickly open the top of the valve body without the need to disassemble the entire electromagnetic valve, and improves the efficiency of replacing and repairing the solenoid. However, the internal parts of the traditional electromagnetic valve are complex and are easily contaminated by impurities, which affects its normal operation. Therefore, there is an urgent need for a pilot-type electromagnetic valve to solve the above problems. SUMMARY
