Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and more specifically to a high-pressure impact resistant electromagnetic valve. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, but not limited to hydraulic or pneumatic systems. There are many types of solenoid valves, each playing a different role in a control system. The most common types are check valves, safety valves, directional control valves, and speed control valves. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility.

[0003] The principle of a typical solenoid valve is as follows: when energized, the electromagnetic force generated by the electromagnetic winding lifts the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring pushes the closing element against the valve seat, thus closing the solenoid valve body. Solenoid valves have many advantages, including compact structure, small size, light weight, low price, fast action, low power consumption, high reliability, and easy maintenance. Furthermore, they provide excellent sealing, preventing leakage of the working fluid medium, and can separate the pressurized fluid from the actuating electronic circuit, eliminating the need for complex intrusive wiring or connections. Therefore, they are used in various fields, such as transportation, refrigeration, chemical safety, water conservancy and hydropower, and medical applications.

[0004] For example, a novel solenoid valve with prior art publication number CN222717581U achieves the switching of the solenoid valve body through electric drive lifting, or it can be manually raised and lowered by rotating a switch and spring, thus achieving manual switching of the solenoid valve body and avoiding the situation where the solenoid valve cannot operate normally in an emergency.

[0005] However, the existing technology described above still has the following problems in use: when using a solenoid valve to control a fluid pipeline, the rapid inflow of high-pressure fluid into the valve will generate a large impact force on the valve, which can easily reduce the sealing between the valve and the solenoid valve body, leading to leakage problems in the solenoid valve. Based on this, the present invention provides a high-pressure impact resistant solenoid valve. Utility Model Content

[0006] To overcome the aforementioned deficiencies in the prior art, this utility model provides a high-pressure impact-resistant solenoid valve. Multiple buffer plates, in conjunction with multiple compression springs, buffer the high-pressure fluid. Simultaneously, the main and secondary diversion holes on the buffer block, along with multiple secondary diversion holes, divert the high-pressure fluid, further enhancing the buffering effect and effectively reducing the impact damage of the high-pressure fluid on the valve. This improves the sealing performance of the solenoid valve body and enhances the safety of fluid delivery, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure impact resistant solenoid valve, comprising a solenoid valve body, an inlet pipe and an outlet pipe respectively provided on both sides of the solenoid valve body, a valve provided inside the solenoid valve body, a buffer assembly provided inside the inlet pipe, the buffer assembly comprising a buffer block, the buffer block being inserted inside the inlet pipe and located on one side of the valve, a main and secondary diversion hole and multiple secondary diversion holes being opened on one side of the buffer block, the outlet ends of the multiple secondary diversion holes being connected to the outlet ends of the main and secondary diversion holes, multiple sleeves arranged in a ring array being embedded on one side of the buffer block, each sleeve having a connecting rod penetrating inside, a compression spring being connected between the connecting rod and the inner wall of the sleeve, and a buffer plate being connected to one end of each of the multiple connecting rods, the buffer plate and the buffer block working together can improve the buffering effect.

[0008] In a preferred embodiment, the number of buffer plates is set to three, and the three buffer plates are arranged in a linear array in front of the buffer block. The three buffer plates in front of the buffer block play a buffering role, thereby effectively improving the buffering effect on high-pressure fluid.

[0009] In a preferred embodiment, a hollow fixing cylinder is fixedly provided on one side of the buffer block. The hollow fixing cylinder is sleeved on the outside of the buffer plate. An annular slot is provided on one side of the liquid inlet pipe. One end of the hollow fixing cylinder is located in the annular slot and fixed by multiple first bolts. The buffer block is fixed inside the liquid inlet pipe by the hollow fixing cylinder, which facilitates quick disassembly and improves maintenance efficiency.

[0010] In a preferred embodiment, the buffer block has mounting holes on one side that are the same number as the sleeves. The sleeves are fixed inside the mounting holes, thereby improving the stability of the sleeves during use.

[0011] In a preferred embodiment, a mounting rod is provided on one side of the buffer block, and a fixing hole adapted to the mounting rod is opened at the center of each buffer plate. The mounting rod passes through the fixing hole and is fixed to the buffer plate by a second bolt. The operator can loosen the second bolt to remove the buffer plate from the mounting rod for replacement.

[0012] In a preferred embodiment, each buffer plate is provided with multiple dispersion holes, which are arranged in a ring array around the fixed hole. By providing multiple dispersion holes on the buffer plate, high-pressure fluid can pass through easily and be dispersed, thereby playing a buffering role.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses multiple buffer plates and multiple compression springs to buffer the high-pressure fluid. At the same time, the main and secondary diversion holes and multiple secondary diversion holes on the buffer block are used to divert the high-pressure fluid, which can further buffer the fluid, effectively reduce the impact damage of the high-pressure fluid on the valve, and thus improve the sealing performance of the solenoid valve body and improve the safety of fluid delivery.

[0015] 2. The buffer block and buffer plate are fixed inside the inlet pipe by the hollow fixing cylinder. Loosen the bolts between the hollow fixing cylinder and the inlet pipe, and the hollow fixing cylinder and buffer assembly can be taken out from the inlet pipe for inspection and replacement. The structure is simple and maintenance is very quick. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a high-pressure impact resistant solenoid valve, including a solenoid valve body 1. The solenoid valve body 1 has an inlet pipe 2 and an outlet pipe 3 on both sides. The solenoid valve body 1 has a valve 4 inside. The inlet pipe 2 has a buffer assembly 5 inside. The buffer assembly 5 includes a buffer block 51. The buffer block 51 is inserted into the inlet pipe 2 and is located on one side of the valve 4. The buffer block 51 has a main and secondary diversion hole 52 and multiple secondary diversion holes 53 on one side. The outlet ends of the multiple secondary diversion holes 53 are all connected to the outlet ends of the main and secondary diversion holes 52.

[0025] The buffer block 51 has multiple sleeves 54 arranged in a circular array on one side. The buffer block 51 has the same number of mounting holes 9 as the sleeves 54 on one side. The sleeves 54 are fixed inside the mounting holes 9 to improve the stability of the sleeves 54. Each sleeve 54 has a connecting rod 55 passing through it. A compression spring 56 is connected between the connecting rod 55 and the inner wall of the sleeve 54. Specifically, one end of the compression spring 56 is fixedly connected to the connecting rod 55, and the other end is fixedly connected to the inner wall of the sleeve 54. Each of the multiple connecting rods 55 has a buffer plate 57 connected to one end. The number of buffer plates 57 is set to three, and the three buffer plates 57 are arranged in a linear array in front of the buffer block 51.

[0026] A hollow fixing cylinder 6 is fixedly provided on one side of the buffer block 51. The hollow fixing cylinder 6 is sleeved on the outside of the buffer plate 57. An annular slot 7 is provided on one side of the liquid inlet pipe 2. One end of the hollow fixing cylinder 6 is located in the annular slot 7 and is fixed by multiple first bolts 8.

[0027] In actual use, the inlet pipe 2 and outlet pipe on the solenoid valve body 1 are connected to the pipeline respectively. When the high-pressure fluid flows into the solenoid valve body 1 quickly, the three buffer plates 57 can first buffer the high-pressure fluid. At the same time, when the buffer plate 57 is impacted by the high-pressure fluid, the multiple connecting rods 55 on the left side of the buffer block 51 move into the sleeve 54 under the push of the buffer plate 57 and squeeze the compression spring 56. The compression spring 56 generates a reaction force that can offset part of the impact force. Subsequently, when the high-pressure fluid flows to the left side of the buffer block 51, it flows out from the right side of the buffer block 51 under the diversion effect of the main and secondary diversion holes 52 and multiple secondary diversion holes 53, and then flows out from the outlet pipe 3 on the right side of the solenoid valve body 1. This can effectively reduce the flow rate of the high-pressure fluid and prevent the high-pressure fluid from impacting the valve 4 and causing loosening. This can effectively improve the sealing performance of the solenoid valve body 1 and thus improve the safety of fluid delivery.

[0028] Refer to the instruction manual appendix Figure 3The buffer block 51 is provided with a mounting rod 10 on one side. Each buffer plate 57 has a fixing hole 11 at its center that matches the mounting rod 10. The mounting rod 10 passes through the fixing hole 11 and is fixed to the buffer plate 57 by a second bolt 12. Each buffer plate 57 has multiple dispersion holes 13, which are arranged in a ring array around the fixing hole 11. By setting multiple dispersion holes 13 on the buffer plate 57, it is possible to facilitate the passage of high-pressure fluid and disperse the high-pressure fluid, thereby playing a buffering role.
