Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electromagnetic valves, and in particular relates to a high-voltage switch electromagnetic valve. Background Art
[0002] Solenoid valves are industrial equipment used for electromagnetic control. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic and pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used are check valves, safety valves, directional control valves, speed regulating valves, etc.
[0003] The patent application with publication number CN219221420U discloses a switch solenoid valve, which includes: a valve body with a valve port; a valve cover; a static iron core; a moving iron core; a sleeve; a spring; a sealing ring; an electromagnetic coil; an electromagnetic housing; and an open retaining ring. The moving iron core is moved by energizing the electromagnetic coil; the static iron core and the moving iron core are coaxially arranged and have an axial gap, and the sleeve is inserted into the hole of the valve cover with its open part; the valve cover and the valve body are connected by threads, and the sealing ring realizes static sealing. The static iron core and the electromagnetic coil are connected by an open retaining ring. A buffer is provided between the moving iron core and the valve body opening to slow down the predetermined speed of the moving iron core during the valve opening process, thereby reducing the impact force between the moving iron core and the valve body, thereby reducing the action noise generated by the moving iron core and the valve body at the moment of impact. The technical solution provided by the present application can solve the problems of slow response time and unstable switching of the switch solenoid valve in the prior art.
[0004] Although a switch solenoid valve in the above patent application has a buffer between the moving iron core and the valve body opening to slow down the predetermined speed of the moving iron core during the valve opening process, it cannot ensure that the pressure in the chamber where the moving iron core is located is the same as the pressure at the oil inlet, etc. When pressure fluctuations occur, it will affect the opening and closing of the valve, causing damage to the internal structure of the solenoid valve, thereby reducing the service life of the solenoid valve.
[0005] In summary, the utility model provides a high-voltage switch solenoid valve to solve the above problems. Utility Model Content
[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a high-pressure switching solenoid valve, which has the advantage that, through the oil passage and the gap, the chamber where the moving iron core is located, the chamber where the guide column is located, and the chamber where the plunger is located are the same as the oil inlet, thereby ensuring that the pressure in each chamber is the same as the oil inlet, thereby reducing the impact of pressure fluctuations on the opening and closing of the valve, thereby increasing the service life of the solenoid valve, and by squeezing the slider to drive the valve port to slide, causing the return spring to undergo elastic deformation, thereby opening the valve port, effectively improving the stability of the solenoid valve structure.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A high-voltage switch solenoid valve comprises: an electromagnetic structure, an interface is installed at the top of one end of the electromagnetic structure, a slot is opened at one end of the interior of the electromagnetic structure, electromagnetic coils are installed on both sides of the interior of the slot, a moving iron core is installed between the two electromagnetic coils, an oil passage cavity is opened inside the moving iron core, and an oil passage 1 is installed inside the oil passage cavity.
[0009] By adopting the above technical solution, the electromagnetic coil is energized, and after being energized, the electromagnetic coil receives a control signal to generate an electromagnetic force, which in turn drives the moving iron core to move to the right, thereby driving the subsequent structure to move to the right. The operation is simple, and the electromagnetic coil and the moving iron core are in a cavity on the inner wall of the electromagnetic structure, which reduces the corrosion of the electromagnetic coil and the moving iron core, thereby increasing the service life of the structure. The electromagnetic coil and the moving iron core are structurally designed to ensure that there is a gap after installation. The gap provides space for the movement of the moving iron core while ensuring the size of the electromagnetic force.
[0010] The utility model is further configured as follows: a sliding groove is provided in the middle of the electromagnetic structure, a transmission block is slidably matched inside the sliding groove, and plungers are fixed on both sides of one end of the transmission block.
[0011] By adopting the above technical solution, electromagnetic force is used to drive the transmission block to move rightward, and the rightward movement of the transmission block pair then drives the plunger to move rightward. The structure is simple, and the plunger can prevent electromagnetic force leakage, thereby reducing damage to the inside of the electromagnetic structure.
[0012] The utility model is further configured as follows: a guide column is fixed to one end of the transmission block away from the plunger, and the other end of the guide column is fixed to the oil passage.
[0013] By adopting the above technical solution, the electromagnetic force of the moving iron core is used to drive the guide column to move to the right, and then drive the transmission block to move to the right. The guide column is the same as the oil passage 1, which ensures that the pressure inside the chamber where the guide column is located is the same as the pressure inside the chamber where the oil passage 1 is located, thereby reducing the impact of pressure fluctuations on the interior of the electromagnetic structure.
[0014] The utility model is further configured as follows: a slider is slidably matched at one end of the sliding groove, an oil passage 2 is fixed to the upper part of one end of the slider close to the guide column, and the other end of the oil passage 2 is connected to the transmission block, valve ports are installed on both sides of the slider, and the two plungers are located on one side of the two valve ports.
[0015] By adopting the above technical solution, the rightward movement of the guide column is utilized to drive, and then drive, the rightward movement of the plunger. The rightward movement of the plunger drives the contact seal between the plunger and the valve seat, so that the valve port is closed, and the chamber where the guide column is located and the chamber where the plunger is located are connected to the oil inlet through the oil passage 2 and the gap inside the electromagnetic structure, thereby ensuring that the pressure in each chamber is the same as the oil inlet, reducing the influence of pressure fluctuations on opening and closing the valve, and improving the service life of the electromagnetic structure.
[0016] The utility model is further configured as follows: a return spring is fixed to one end of the two valve ports away from the plunger, a connecting block is fixed to the other end of the return spring, a fixing block is fixedly connected between the connecting block and the electromagnetic structure, a valve seat is installed on the middle circumference of the return spring, and one end of the valve seat is fixed to the inside of the electromagnetic structure.
[0017] By adopting the above technical scheme, the electromagnetic coil is energized to drive the moving iron core to move to the right, thereby driving the guide column and the plunger to compress the return spring, and the return spring undergoes elastic deformation, thereby driving the plunger to move to the right and contact and seal with the valve seat. The contact and seal between the plunger and the valve seat closes the valve port. When the electromagnetic coil is powered off, the return spring recovers its deformation, thereby driving the plunger, the guide column and the moving iron core to move to the left, thereby opening the valve port. The return spring can store energy when stretched or compressed. The return spring has an automatic reset function, which can effectively prevent operating errors and malfunctions. The return spring occupies a small space, which is convenient for the work of other structures. The return spring can improve the stability of the electromagnetic structure during operation, thereby improving the working efficiency of the electromagnetic structure.
[0018] The utility model is further configured as follows: an oil inlet is provided at an upper portion of one end of the return spring of the electromagnetic structure, and an oil outlet is provided at an upper portion of the electromagnetic structure.
[0019] By adopting the above technical solution, the electromagnetic coil is energized, the moving iron core moves to the right, pushing the guide column and the plunger to compress the return spring to move to the right, so that the plunger contacts and seals with the valve seat, thereby closing the valve port. At this time, the oil inlet and the oil outlet are in a closed state. When the electromagnetic coil is powered off, the return spring recovers its deformation to open the valve port, and the oil inlet and the oil outlet are in a connected state. The chambers where the oil outlet, oil inlet, moving iron core, guide column and plunger are located are connected to the electromagnetic structure gap through oil passage 1 and oil passage 2, thereby ensuring that the pressure in each chamber is the same as that at the oil inlet, reducing the influence of pressure fluctuations on opening and closing the valve.
[0020] The utility model is further configured as follows: a rectangular block is fixed on one side of the electromagnetic structure away from the oil outlet, a connecting rod is fixedly connected between the rectangular block and the electromagnetic structure, and a rubber soft sleeve is fixed in the gap between the connecting rod and the electromagnetic structure.
[0021] By adopting the above technical solution, the rectangular block is fixed to the electromagnetic structure by fasteners, wherein the fasteners may be screws, screws or bolts. The fasteners are used to ensure the sealing of the electromagnetic structure, and prevent fine impurities from entering the electromagnetic structure, thereby causing changes in the internal medium of the electromagnetic structure. The working efficiency of the solenoid valve can be improved while extending the service life of the electromagnetic structure.
[0022] In summary, the beneficial technical effects of the utility model are:
[0023] 1. This structure makes the chamber where the moving iron core is located, the chamber where the guide column is located, and the chamber where the plunger is located the same as the oil inlet through the oil passage and the gap, ensuring that the pressure in each chamber is the same as the oil inlet, thereby reducing the impact of pressure fluctuations on the opening and closing of the valve, thereby increasing the service life of the solenoid valve, and by squeezing the slider to drive the valve port to slide, causing the return spring to undergo elastic deformation, thereby opening the valve port, effectively improving the stability of the solenoid valve structure.
[0024] 2. The rectangular block is fixed to the electromagnetic structure by fasteners, which ensures the sealing of the electromagnetic structure and prevents fine impurities from entering the electromagnetic structure, thereby causing the internal medium of the electromagnetic structure to change, thereby improving the working efficiency of the electromagnetic structure and extending the service life of the solenoid valve.
