Description

Technical Field

[0001] This utility model belongs to the field of high-pressure solenoid valve technology, and in particular relates to a high-pressure solenoid valve. Background Technology

[0002] A high-pressure solenoid valve is a type of solenoid valve used for pipeline control in high-pressure environments. It typically consists of a coil, a magnetic core, a valve body, and sealing materials. It primarily controls the valve's opening and closing by altering the magnetic field generated within the electromagnet coil, thereby regulating the input and output of the medium.

[0003] When the solenoid valve is de-energized, the sealing end inside the solenoid valve is kept in a closed and sealed state by a spring. However, after the solenoid valve has been used in a high temperature and high pressure environment for a long time, the spring may deform, which may cause the subsequent sealing components to not seal tightly, resulting in continuous leakage of the solenoid valve. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-pressure solenoid valve, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-pressure solenoid valve, comprising a solenoid valve element and an electromagnetic assembly disposed on the upper end face of the solenoid valve element, and further comprising:

[0007] The inlet port is located on one side of the solenoid valve, and the solenoid valve has a connecting conduit inside. The other end of the solenoid valve has a discharge port.

[0008] The filtration mechanism, located inside the connecting conduit, is used to filter the liquid entering the connecting conduit.

[0009] The sealing component slides and engages inside the connecting conduit; the electromagnetic assembly contains an electromagnet assembly.

[0010] A limiting mechanism is installed at the upper end of the sealing component to prevent the sealing component from shifting or shaking.

[0011] Furthermore, the inlet port is connected to the outlet port via a connecting conduit, and the outer surfaces of the inlet port and the outlet port are provided with threads.

[0012] Furthermore, the filtering mechanism includes a connecting groove, a fixing plate, a connecting plate, and a filter screen. The connecting groove is symmetrically opened on the left and right sides of the lower end face of the solenoid valve. The fixing plate is slidably engaged with the lower end of the solenoid valve. The connecting plate is symmetrically fixed on the left and right sides of the upper end face of the fixing plate, and the connecting plate is slidably engaged with the inner side of the connecting groove. The filter screen is disposed on the upper end of the inner side of the connecting plate, and the filter screen corresponds to the central axis of the inlet port and the outlet port.

[0013] Furthermore, the lower end face of the solenoid valve is provided with a limiting groove, the limiting groove has a stepped structure, and the fixing plate is slidably embedded in the limiting groove.

[0014] Furthermore, a connecting rod is fixed to the upper end face of the sealing component, and the cross-section of the connecting rod is a "T" shaped structure. A return spring is sleeved on the upper end face of the connecting rod, and the other end of the return spring is in contact with the inner wall of the electromagnetic component.

[0015] Furthermore, the limiting mechanism includes a limiting member, a limiting rod, a connecting slide, and a push spring. The limiting member is symmetrically arranged on the left and right sides of the connecting rod. The limiting rod is rotatably connected to the tail end of the limiting member. The connecting slide is rotatably connected to the tail end of the limiting rod, and the other end of the connecting slide slides along the upper part of the electromagnetic assembly for adjustment. The push spring is fixed inside the electromagnetic assembly, and the other end of the push spring is in contact with the connecting slide.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses a limiting groove to constrain the fixing plate, and the connecting plate at the upper end of the fixing plate can extend into the connecting conduit inside the solenoid valve. This allows the liquid entering the solenoid valve to be filtered through the filter screen, preventing small impurities from entering the valve body, which could damage the valve core, cause leakage, and extend the service life of the solenoid valve. Furthermore, the limiting mechanism not only limits the position of the connecting rod, preventing it from shifting or shaking, but also facilitates subsequent resetting and adjustment of the connecting rod, ensuring a tight seal between the sealing component and the connecting conduit.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is a high-pressure solenoid valve, including a solenoid valve component 1 and an electromagnetic assembly 2 disposed on the upper end face of the solenoid valve component 1, and further including:

[0027] The inlet port 3 is located on one side of the solenoid valve 1. The solenoid valve 1 has a connecting conduit 4 inside and a discharge port 5 at the other end. The inlet port 3 is connected to the discharge port 5 through the connecting conduit 4. The outer surfaces of the inlet port 3 and the discharge port 5 are threaded. The threads on the outer surfaces of the inlet port 3 and the discharge port 5 facilitate the subsequent connection of the solenoid valve 1 to the pipeline, thereby facilitating the subsequent installation of the solenoid valve 1.

[0028] A filtration mechanism, located inside the connecting conduit 4, is used to filter the liquid entering the connecting conduit 4. A limiting groove 6 is provided on the lower end face of the solenoid valve 1. The limiting groove 6 has a stepped structure, and the fixing plate 8 slides into the limiting groove 6. The limiting groove 6 limits the fixing plate 8, preventing it from shifting or shaking. The filtration mechanism includes a connecting groove 7, a fixing plate 8, a connecting plate 9, and a filter screen 10. The connecting groove 7 is symmetrically located on the left and right sides of the lower end face of the solenoid valve 1. The fixing plate 8 is slidably engaged inside the lower end of the solenoid valve 1. The connecting plate 9 is symmetrically fixed on the left and right sides of the upper end face of the fixing plate 8. The filter screen 10 is slidably engaged inside the connecting groove 7. The filter screen 10 is set inside the upper part of the connecting plate 9, and the filter screen 10 corresponds to the central axis of the inlet port 3 and the outlet port 5. The connecting groove 7 can limit the connecting plate 9 and prevent the connecting plate 9 from shifting. Then, the connecting plate 9 can be slidably embedded in the solenoid valve 1, so that the solenoid valve 1 can be slidably inserted into the connecting conduit 4. Since the filter screen 10 and the connecting conduit 4 are on the same vertical center line, the liquid or gas entering the connecting conduit 4 can be filtered to prevent small impurities from entering the valve body, causing damage to the valve core and leakage, thus extending the service life of the solenoid valve.

[0029] The sealing component 11 is slidably engaged inside the connecting conduit 4. The electromagnetic component 2 is equipped with an electromagnet component 18. A connecting rod 12 is fixed to the upper end face of the sealing component 11, and the cross-section of the connecting rod 12 is a "T" shaped structure. A return spring 13 is sleeved on the upper end face of the connecting rod 12, and the other end of the return spring 13 is in contact with the inner wall of the electromagnetic component 2. By slidably engaging the sealing component 11 inside the connecting conduit 4, the inlet port 3 and the outlet port 5 can be sealed. Then, the return spring 13 can reset the connecting rod 12, thereby ensuring the sealing effect between the sealing component 11 and the connecting conduit 4, thus avoiding the situation of loose sealing, which would cause the solenoid valve to leak continuously.

[0030] A limiting mechanism, located at the upper end of the sealing member 11, is used to prevent the sealing member 11 from shifting or shaking. The limiting mechanism includes a limiting member 14, a limiting rod 15, a connecting slide 16, and a push spring 17. The limiting member 14 is symmetrically arranged on the left and right sides of the connecting rod 12. The limiting rod 15 is rotatably connected to the tail end of the limiting member 14. The connecting slide 16 is rotatably connected to the tail end of the limiting rod 15, and the other end of the connecting slide 16 slides along the upper part of the electromagnetic assembly 2 for adjustment. The push spring 17 is fixed inside the electromagnetic assembly 2, and the other end of the push spring 17 is connected to the connecting slide 16. The limiting member 14 is rotatably connected to the limiting rod 15 through the setting limiting member 14. The connecting slide 16 connected to the upper end of the limiting rod 15 can slide along the inside of the electromagnetic component 2, thereby limiting the position of the connecting rod 12 and preventing the connecting rod 12 from deviating or shaking. Then, the setting push spring 17 can push the connecting slide 16 to reset, so that the position of the connecting slide 16 can be pulled and adjusted when the power is off, which can reduce the burden on the reset spring 13. At the same time, it can also ensure the tightness of the subsequent sealing connection between the sealing member 11 and the connecting conduit 4.

[0031] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
