Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel explosion-proof valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveyed medium. They have functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] The existing explosion-proof valves are not equipped with sealing devices, so pressure relief may occur during use, which may cause water leakage or valve explosion, greatly reducing the safety and sealing effect of the new explosion-proof valves, and also reducing the explosion-proof effect; the existing new explosion-proof valves are not equipped with multiple sealing devices and only rely on button covers to stop water. When the water pressure is too high, the valve is easily blown, greatly reducing the safety and explosion-proof effect of the new explosion-proof valves. Utility Model Content

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, they are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0014] In addition, if the descriptions of "first", "second", etc. are involved in the present utility model, they are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0016] See also Figure 1 and Figure 2 The utility model embodiment provides a new explosion-proof valve, including a valve body 1, the outer surface of one end of the valve body 1 is sleeved with a button cover 2, the bottom end of the inner top wall of the button cover 2 is fixedly provided with a threaded rod 3, the main body of the threaded rod 3 is located inside the valve body 1, the surface of the threaded rod 3 is threadedly connected with the inner side wall of the valve body 1, the bottom end of the threaded rod 3 is fixedly provided with a first sealing block 4, the bottom end of the first sealing block 4 is fixedly provided with a clamping block 5, the inside of the water outlet end of the valve body 1 corresponding to the bottom end of the clamping block 5 is provided with a block 8, the block 8 is fixedly connected to the inner wall of the water outlet end of the valve body 1, a water outlet 9 is penetrated in the middle of the block 8, a second sealing block 6 is fixedly provided on the top of the block 8, and a clamping groove 7 matching the size of the clamping block 5 is recessed on the top of the second sealing block 6.

[0017] Optionally, a sealing plug 10 is fixedly provided at the bottom end of the first sealing block 4 , and the side wall of the water outlet 9 is threadably matched with the surface of the sealing plug 10 .

[0018] When in use, the threaded rod 3 is driven downward by rotating the button cover 2, thereby driving the first sealing block 4 to move downward, so that the first sealing block 4 and the second sealing block 6 are tightly fitted. When the first sealing block 6 and the second sealing block 8 are tightly fitted, the card block 5 can be inserted into the card groove 7, thereby improving the sealing between the first sealing block 4 and the second sealing block 6. At the same time, the first sealing block 4 drives the sealing plug 10 to rotate into the water outlet 9, thereby improving the firmness of the button cover 2 and the firmness of the first sealing block 4 and the second sealing block 6, avoiding the situation where the button cover 2 is rushed open due to excessive water pressure, and achieving a double sealing effect through the first sealing block 6 and the second sealing block 8 and the water plug 12, greatly improving the safety and explosion-proof effect of the new explosion-proof valve.

[0019] The embodiments of the present invention have been described so far in conjunction with the preferred embodiments shown in the accompanying drawings.
