Description

Technical Field

[0001] The present application relates to the technical field of solenoid valves, and in particular to a flameproof electromagnetic coil. Background Art

[0002] Solenoid valves are electromagnetically controlled industrial devices, essential automation components for controlling fluids. They are classified as actuators, not limited to hydraulic or pneumatic systems. They are used in industrial control systems to adjust the direction, flow, speed, and other parameters of media. Solenoid valves can be combined with various circuits to achieve desired control, ensuring both precision and flexibility. There are many different types of solenoid valves, each serving different functions within a control system. The most commonly used are check valves, safety valves, directional control valves, and speed control valves.

[0003] During the use of the solenoid valve, electric sparks will be generated inside the electromagnetic coil, so the electromagnetic coil is sealed and wrapped to prevent the electric sparks generated inside the electromagnetic coil from being discharged outside. This type of solenoid valve is a flameproof solenoid valve, but the electromagnetic coil inside the flameproof solenoid valve will be damaged after long-term use, so the electromagnetic coil needs to be disassembled and repaired. However, the electromagnetic coil is tightly wrapped outside, making it very inconvenient to disassemble the electromagnetic coil, which reduces the efficiency of repairing the electromagnetic coil.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings.

[0023] The embodiment of the present application discloses an explosion-proof solenoid valve.

[0024] Referring to Figure 1 and Figure 2 , it includes a valve housing 1 and an electromagnetic coil body 2. The electromagnetic coil body 2 is located inside the valve housing 1. The electromagnetic coil body 2 includes a coil body 3, a support frame 4, a static iron core assembly 5 and a moving iron core assembly 6. The coil body 3 is sleeved on the periphery of the support frame 4. The static iron core assembly 5 and the moving iron core assembly 6 are located inside the support frame 4. An outer shell 7 is sleeved on the outer periphery of the electromagnetic coil body 2. The outer shell 7 includes an upper half shell 8 and a lower half shell 9. A through hole 10 for the support frame 4 to pass through is opened at the bottom of the lower half shell 9.

[0025] The vertical cross-sections of the upper half shell 8 and the lower half shell 9 are both in a "U" shape. A ring block 11 is integrally provided circumferentially at the lower end of the upper half shell 8. A ring groove 12 for the ring block 11 to be inserted and matched is opened circumferentially at the upper end of the lower half shell 9. With the mutual cooperation of the ring block 11 and the ring groove 12, the contact area between the upper half shell 8 and the lower half shell 9 is increased, and the sealing performance between the upper half shell 8 and the lower half shell 9 is improved.

[0026] An anti-collision sponge 13 is placed at the inner bottom of the upper half shell 8. The outer end of the anti-collision sponge 13 can be used for the upper end of the electromagnetic coil body 2 to cooperate. The anti-collision sponge 13 can be recessed according to the shape of the upper end of the electromagnetic coil body 2, which can prevent the upper half shell 8 from colliding with the upper end of the electromagnetic coil body 2.

[0027] Referring to Figure 2 , Figure 3 and Figure 4The lower end of the upper half shell 8 is rotatably connected to four fixing buckles 14. Fixing buckles 14 include a connecting bar 15 and a fixing bar 16. The upper end of fixing bar 16 is rotatably connected to the lower end surface of the upper half shell 8. One end of the connecting bar 15 is bolted to the lower end of the fixing bar 16. The vertical cross-section of fixing buckle 14 is L-shaped. Four matching grooves 17 for the fixing buckles 14 are evenly distributed around the outer wall of the lower half shell 9. The outer wall of the fixing buckle 14 is flush with the outer wall of the lower half shell 9. The four fixing buckles 14 are rotated so that one end of the fixing buckle 14 slides out from the interior of the lower half shell 9. The upper half shell 8 and the lower half shell 9 are then separated, exposing the electromagnetic coil to the outside world, and the electromagnetic coil can then be repaired.

[0028] A fixing assembly 18 is placed between the fixing buckle 14 and the matching groove 17. The fixing assembly 18 includes a locking block 19 and a drive bar 20. The upper end surface of the fixing bar 16 is provided with an adjustment groove 21. One end of the adjustment groove 21 extends to the fixing bar 16 and is opened through. One end of the drive bar 20 is integrally provided with the side wall of the adjustment groove 21, and the other end of the drive bar 20 extends to the open end on one side of the adjustment groove 21. The lower end of the locking block 19 is integrally provided with the upper side wall of the drive bar 20. The bottom of the matching groove 17 of the lower half shell 9 is provided with a locking groove 22 for the locking block 19 to engage. By moving the drive bar 20, the drive bar 20 bends toward the bottom of the adjustment groove 21, which then drives the locking block 19 to slide out of the locking groove 22. After that, the fixing bar 16 can slide out from the lower end of the lower half shell 9, and the upper half shell 8 and the lower half shell 9 can then be disassembled.
