An explosion-proof solenoid valve is a solenoid valve designed specifically for flammable and explosive fluids such as hydrogen energy. Its design and manufacturing follow strict explosion-proof standards. Through a special explosion-proof electromagnetic mechanism, it can prevent sparks, arcs or high temperatures generated by electrical equipment during operation from igniting explosive gas mixtures in the surrounding environment, thereby avoiding explosion accidents.

[0004] For example, the above-mentioned existing explosion-proof solenoid valve installs a fixing plate on the explosion-proof solenoid valve body through a clamping assembly, and drives one end of the supporting assembly through a rack, so as to support and reinforce the water pipes installed on both sides of the explosion-proof solenoid valve. In the specific implementation process, the clamping mechanism is directly fixed and integrated at the inlet and outlet ends, which easily causes obstruction to the flange connection between the external pipeline and the inlet and outlet ends. Therefore, it is urgent to propose a corresponding hydrogen energy explosion-proof solenoid valve to solve the above problems. Utility Model Content

[0025] When the external pipeline is a threaded interface, the external pipeline can be directly connected to the threaded pipe 8, and when the external pipeline is a flange interface, the threaded pipe 8 is separated from the flange 2 7, and the external flange and the flange 1 4 are fixed by the cooperation of the fastening rod 5 and the fastening sleeve 6, so that the solenoid valve can adapt to different installation requirements. On this basis, when the threaded connection is selected, the cross plate 10 is passed through the fixing sleeve 9, and the limit frame 12 is moved to be sleeved on the connection between the threaded pipe 8 and the external pipeline, and the positioning of the cross plate 10 is completed by the locking rod 16. At this time, the limit frame 12 can be externally The connection between the external pipe and the threaded pipe 8 is supported and reinforced. Similarly, when the flange connection is selected, the cross plate 10 passes through the fixing sleeve 9, the limit frame 12 overlaps the outside of the external pipe, and the limit frame 12 is moved until it overlaps the end of the fastening rod 5. After the cross plate 10 is positioned, the friction force generated between the limit frame 12 and the fastening rod 5 can effectively limit the axial looseness of the fastening rod 5, thereby completing the support and reinforcement of the connection between the external flange and the flange 4, increasing the flexibility of the solenoid valve connection while ensuring the stability of the connection, and not hindering the connection process;

[0026] It should be noted that the valve body 1 and the explosion-proof electromagnetic mechanism 2 are both referenced prior arts, and therefore will not be described in detail here.

[0027] Specifically, Figure 2 and Figure 4As shown, the reinforcement component includes a reinforcement component limit frame 12, and the outer wall of the arc-shaped end of the limit frame 12 is fixedly connected with a slide rod 11 that is slidably connected to the cross plate 10, and a spring 14 is fixedly connected between the outer wall of the arc-shaped end of the limit frame 12 and the cross plate 10. When the threaded connection is selected, the cross plate 10 is passed through the fixed sleeve 9, and the limit frame 12 is moved to be sleeved on the connection between the threaded pipe 8 and the external pipe. The positioning of the cross plate 10 is completed by the locking rod 16. At this time, the limit frame 12 can support the connection between the external pipe and the threaded pipe 8. Reinforcement. Similarly, when selecting the flange connection, the cross plate 10 passes through the fixing sleeve 9, the limit frame 12 overlaps the outside of the external pipe, and the limit frame 12 is moved until it overlaps the end of the fastening rod 5. After the cross plate 10 is positioned, the friction force generated between the limit frame 12 and the fastening rod 5 can effectively limit the axial loosening of the fastening rod 5. The inner surface wall of the arc-shaped end of the limit frame 12 is fixedly connected with a rubber pad 15, and the side of the limit frame 12 close to the fastening rod 5 is fixedly connected with a rubber pad 2 18 to ensure the stability of the contact.

[0028] Specifically, Figure 2 and Figure 3 As shown, a positioning rod 13 is screwed into the inner surface wall of the open end of the cross plate 10, and the open end of the positioning rod 13 abuts against the outer surface wall of the slide bar 11. The spring 14 ensures the stability of the position of the limit frame 12. Before the limit frame 12 is used for support and reinforcement, the positioning rod 13 is screwed into the cross plate 10, and the positioning rod 13 abuts against the outer surface wall of the slide bar 11. At this time, the spring 14 is in a compressed state, which facilitates the rapid combination of the cross plate 10 and the fixed sleeve 9.

The interference fit ensures the position of the rubber plug 17 itself, and the rubber plug 17 can limit the loosening of the locking rod 16 through friction.

[0030] Working principle: When the external pipeline is a threaded interface, the external pipeline can be directly connected to the threaded pipe 8, and when the external pipeline is a flange interface, the threaded pipe 8 is separated from the flange 2 7, and the external flange and the flange 1 4 are fixed by the cooperation of the fastening rod 5 and the fastening sleeve 6, so that the solenoid valve can adapt to different installation requirements. On this basis, when the threaded connection is selected, the cross plate 10 is passed through the fixing sleeve 9, and the limit frame 12 is moved to be sleeved on the connection between the threaded pipe 8 and the external pipeline. The positioning of the cross plate 10 is completed by the locking rod 16. At this time, the limit frame 12 can support and reinforce the connection between the external pipeline and the threaded pipe 8. Similarly, when the flange connection is selected, the cross plate 10 passes through the fixing sleeve 9, the limit frame 12 is overlapped on the outside of the external pipeline, and the limit frame 12 is moved. Until it overlaps the end of the fastening rod 5. After the cross plate 10 is positioned, the friction force generated between the limit frame 12 and the fastening rod 5 can effectively limit the axial loosening of the fastening rod 5, thereby completing the support and reinforcement of the connection between the external flange and the flange 4, increasing the flexibility of the solenoid valve connection while ensuring the stability of the connection and not hindering the connection process. The spring 14 ensures the stability of the position of the limit frame 12. Before the limit frame 12 is used for support and reinforcement, the positioning rod 13 is screwed with the cross plate 10, and the positioning rod 13 abuts against the outer wall of the slide rod 11. At this time, the spring 14 is in a compressed state, which facilitates the rapid combination of the cross plate 10 and the fixing sleeve 9. Subsequently, only the positioning rod 13 needs to be separated, thereby improving the convenience of using the hydrogen energy explosion-proof solenoid valve.
