Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a pressure relief valve anti-loss structure. Background Technology

[0002] Some existing valve bodies are equipped with a pressure relief structure, and this pressure relief structure is generally detachable. Furthermore, after the pressure relief structure is disassembled, an anti-loss structure is installed to prevent the pressure relief structure from being lost.

[0003] For example, patent document CN216242521U discloses an anti-loss pressure relief plug, which includes a plugging component disposed at the pressure relief hole of the main body. The anti-loss pressure relief plug also includes a limiting component disposed at one end of the plugging component and inserted into the main body. When the plugging component is depressurized and detached from the pressure relief hole, the limiting component abuts against the inner wall of the main body to prevent the plugging component from falling off.

[0004] However, in the above-mentioned technologies, the pressure relief structure cannot be completely removed after the anti-loss structure is installed.

[0005] To address this issue, a pressure relief valve anti-loss structure is proposed to solve the aforementioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressure relief valve anti-loss structure, which has the advantages of effectively preventing the pressure relief valve from being lost and not affecting the removal of the pressure relief valve.

[0007] The technical solution adopted by this utility model to solve the problem is: a pressure relief valve anti-loss structure, including: a pressure relief valve and a connecting column installed on the valve body, wherein a connecting rope is provided on the connecting column, and one end of the connecting rope is fixedly connected to the pressure relief valve.

[0008] As a further improvement to the above technical solution, an annular groove is provided on the connecting column, and a ring is provided at the bottom end of the connecting rope, with the ring embedded in the annular groove.

[0009] As a further improvement to the above technical solution, a connecting ring is fixedly installed at one end of the connecting rope, and the connecting ring is fixedly connected to the pressure relief valve by bolts.

[0010] As a further improvement to the above technical solution, the connecting rope is made of an elastic material.

[0011] As a further improvement to the above technical solution, the pressure relief valve is connected to the valve body by bolts.

[0012] The beneficial effect of this utility model is that by setting a connecting rope to connect the pressure relief valve to the valve body, the pressure relief valve is prevented from being lost after disassembly. Attached Figure Description

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 2 A pressure relief valve anti-loss structure includes: a pressure relief valve 1 and a connecting post 2 installed on a valve body. A connecting rope 3 is provided on the connecting post 2, and one end of the connecting rope 3 is fixedly connected to the pressure relief valve 1. After the pressure relief valve 1 is removed, it can remain connected to the valve body through the connecting rope 3, which can prevent the pressure relief valve 1 from being lost after removal.

[0021] In a preferred embodiment, the connecting column 2 has an annular groove 21, and the bottom end of the connecting rope 3 has a ring 31, which is embedded in the annular groove 21. This facilitates the connection between the connecting rope 3 and the connecting column 2, and also allows the pressure relief valve 1 to be placed on either side of the connecting column 2 after removal.

[0022] In a preferred embodiment, a connecting ring 32 is fixedly installed at one end of the connecting rope 3, and the connecting ring 32 is fixedly connected to the pressure relief valve 1 by bolts. This facilitates the connection between the connecting rope 3 and the pressure relief valve 1.

[0023] In a preferred embodiment, the connecting rope 3 is made of an elastic material. This further facilitates the connection between the connecting rope 3 and the connecting post 2.

[0024] In a preferred embodiment, the pressure relief valve 1 is connected to the valve body by bolts.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
