Description

Technical Field

[0001] This utility model relates to the field of gas safety equipment technology, and in particular to a self-closing valve safety base. Background Technology

[0002] A self-closing valve is a safety device installed in fluid systems such as gas pipelines and water supply pipelines. Its core function is to automatically close the valve and cut off the fluid supply when abnormal conditions occur in the pipeline (such as gas leakage, excessively high or low pressure, abnormally increased flow, etc.), thereby preventing accidents (such as gas explosion, water leakage, etc.). To prevent the self-closing valve from loosening or shifting, a base is needed to fix it.

[0003] Traditional self-closing valves are often directly exposed on walls or pipes, lacking a dedicated protective structure. They are prone to component aging due to kitchen grease and moisture, or deformation and loosening of the valve body due to external impacts (such as accidental contact during kitchen utensil handling or cleaning), increasing the risk of gas leakage. To address these issues, a safety base for self-closing valves is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a safety base for a self-closing valve, which aims to improve the problem that traditional self-closing valves in the prior art are mostly directly exposed on the wall or pipe. Due to the lack of a special protective structure, they are easily affected by kitchen oil and water vapor, which can lead to component aging, or the valve body can be deformed or the interface can be loosened due to external impact, thereby increasing the risk of gas leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-closing valve safety base, comprising a base, wherein a protective mechanism is provided on the top of the base;

[0006] The protective mechanism includes a protective box, a connecting box that contacts the right side of the protective box, a movable plate that is rotatably connected to the bottom of both the protective box and the connecting box, a card seat that is fixedly connected to the top of the base, a self-closing valve that is engaged with the top of the card seat, a limit component that is provided on the top of the protective box, a pad that is fixedly connected to the bottom of both the protective box and the connecting box, and a sealing component that is provided on the left side of the connecting box.

[0007] As a further description of the above technical solution:

[0008] The limiting component includes a fixing plate fixedly connected to the top of the protective box, a plug-in plate fixedly connected to the right end of the fixing plate, a connecting block fixedly connected to the top of the connecting box, and the outer wall of the plug-in plate snapping into the inner wall of the connecting block.

[0009] As a further description of the above technical solution:

[0010] The base has a groove at its top, and the bottom of the movable plate is slidably connected to the inner wall of the groove.

[0011] As a further description of the above technical solution:

[0012] A semi-circular groove is formed on one side of the connecting box and the protective box that are close to each other, and a cavity is formed on the other side of the protective box and the connecting box that are close to each other.

[0013] As a further description of the above technical solution:

[0014] The bottom of the pad is in contact with the top of the base.

[0015] As a further description of the above technical solution:

[0016] The sealing assembly includes a sealing gasket fixedly connected to the left side of the connecting box, a connecting gasket fixedly connected to the inner surface of the semi-circular groove, sealing blocks fixedly connected to the bottom of both the connecting box and the protective box, and a rubber gasket fixedly connected to the bottom left side of the connecting box.

[0017] As a further description of the above technical solution:

[0018] The upper part of the movable plate is in contact with the inner side of the sealing block.

[0019] As a further description of the above technical solution:

[0020] The left sides of both the sealing gasket and the rubber gasket are in contact with the right side of the protective box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the base, card seat and protective mechanism cooperate with each other, and the sliding plate slides along the base groove to achieve quick opening and closing. When opening, it is only necessary to move to both sides to release the limit. Flipping the connecting box and protective box can expose the self-closing valve, which is convenient for daily inspection and maintenance. In addition, when storing, the connecting box and protective box can be closed to protect the self-closing valve. The whole process can be opened, closed and fixed without tools, and the operation is simple and convenient.

[0023] 2. In this utility model, through the mutual cooperation between the sealing components and other structures, a closed space is formed by the closed structure of the protective box and the connecting box. Combined with the multi-layer sealing design of the sealing components, it can effectively isolate the self-closing valve from the erosion of kitchen oil, water vapor and dust.
