Description

Technical Field

[0001] The utility model relates to the technical field of gas source box applications, in particular to a stop valve used for connecting gas source box pipelines. Background Art

[0002] The gas source pipe stop valve plays a very important role in the control valve gas source pipeline. The gas source pipe stop valve mainly plays the role of cutting off or connecting the fluid, as well as regulating the flow and pressure in the control valve gas source pipeline. The stop valve is usually a forced sealing valve. When the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. This type of valve can effectively control the flow of media such as gas and liquid, thereby protecting the safe operation of the pipeline system.

[0003] When the internal pipelines of the existing gas source box are connected and installed, a stop valve is generally required to be connected to the main pipeline to open and close the gas in the entire gas source box, which is convenient for later disconnection and maintenance. When the stop valve is in use, it generally requires staff to manually tighten and loosen it, which increases the cumbersomeness of use. Long-term exposure to the outside world will cause damage to the internal screw, thereby reducing the flexibility of the stop valve in use. At the same time, it cannot be quickly closed in the event of a pipeline leak. Therefore, the utility model proposes a stop valve for connecting the pipeline of the gas source box.

The interior of the valve body 100 is fixedly connected to an internal plate 103, which is arranged in a Z shape, and the outer wall of the sealing sleeve 200 is provided with a U-shaped groove. The sealing sleeve 200 is connected to the inner wall of the internal plate 103 through the U-shaped groove of the outer wall, so that the sealing sleeve 200 is used to seal the opening of the internal plate 103 to prevent gas leakage at the opening when closed.
