Description

Technical Field

[0001] The invention relates to a stop valve, in particular to a stop valve which is convenient for internal cleaning, and belongs to the technical field of stop valves. Background Art

[0002] The stop valve is the most widely used valve. The friction between the sealing surfaces is small during opening and closing, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is suitable not only for medium and low pressures, but also for high pressures. The closing principle of the stop valve is to rely on the valve stem pressure to make the plug plate sealing surface fit closely with the valve body sealing surface to prevent the flow of medium.

[0003] In order to prevent the valve body from being blocked, a filter plate is installed in the valve body for filtering. However, after the filter plate in the valve body is used for a long time, debris will accumulate on the surface of the filter plate. If the valve body cannot be opened, it is difficult to effectively clean the filter plate in the valve body. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a stop valve that is easy to clean inside.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: The closure of the valve body is connected with a valve core, and the closure of the valve body is connected with a valve stem at the bottom of the valve body, and a valve stem is provided at the bottom of the valve body, and a valve stem is provided at the bottom of the valve body, and a valve stem is provided at the bottom of the valve body.

[0006] Preferably, the fixed grooves are all opened at the lower end of the valve body and are evenly distributed outside the sewage outlet, a fixed slider is fixedly connected in the fixed groove, the lower end of the fixed slider passes through the fixed groove and is fixedly connected with a baffle, the baffle is slidably connected to the side wall of the lower end of the valve body, and the upper end of the baffle close to one side is in contact with the lower end of the sealing cover.

[0007] Preferably, the fixed slider is fixedly connected to a connecting spring, and one end of the connecting spring away from the fixed slider is fixedly connected to the side wall of the fixing groove.

[0008] The present invention proposes a stop valve which is easy to clean internally, and has the beneficial effect that by pulling the baffle of the fixing mechanism, the fixing slide block is located in the fixing groove and slides, and the connecting spring is compressed, the baffle and the sealing cover can be disconnected, and finally the sealing cover can be taken out from the sewage outlet, and the filter plate can be taken out from the valve body at the same time, so that the filter plate can be cleaned conveniently and the situation that the debris accumulated on the surface of the filter plate is difficult to clean can be avoided.

DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0012] Reference Figure 1-5The present invention provides a technical solution: a stop valve that is easy to clean internally, comprising a valve body 1, a valve core 2 is fixedly connected to the middle position of the upper end of the valve body 1, a liquid inlet 3 and a liquid outlet 4 are respectively opened in the valve body 1 and located at both ends of the valve body 1, a connecting pipe 5 is fixedly connected in the valve body 1 and located at the connection between the liquid inlet 3 and the liquid outlet 4, a limit plate 6 is fixedly connected in the connecting pipe 5 and located in the middle position of the connecting pipe 5, a filter plate 10 is clamped in the connecting pipe 5 and located at the lower end of the limit plate 6, a fixing mechanism 9 is arranged at the lower end of the valve body 1 and at a position corresponding to the filter plate 10, a threaded rod 7 is threadedly connected to the valve core 2, the lower end of the threaded rod 7 passes through the valve core 2 and is located in the valve body 1, and a plug plate 8 is fixedly connected to one end of the threaded rod 7 located in the valve body 1, and the plug plate 8 is clamped in the connecting pipe 5 and located above the limit plate 6.

[0013] The fixing mechanism 9 includes a sewage outlet 91 and a fixing groove 95. The sewage outlet 91 is opened at the lower end of the valve body 1 and its position corresponds to the filter plate 10. A sealing cover 92 is clamped in the sewage outlet 91. A connecting rod 93 is fixedly connected between the sealing cover 92 and the filter plate 10. A sealing gasket 94 is fixedly connected to the side wall of the lower end of the sewage outlet 91. The lower end of the sealing gasket 94 contacts the outer side of the upper end of the sealing cover 92. The fixing grooves 95 are all opened at the lower end of the valve body 1 and are evenly distributed on the outer side of the sewage outlet 91. A fixed slider 96 is fixedly connected in the fixing groove 95. The lower end of the fixed slider 96 passes through the fixing groove 95 and is fixedly connected to a baffle 98. The baffle 98 is slidably connected to the valve The side wall of the lower end of the body 1 and the upper end of the side close to the baffle 98 are in contact with the lower end of the sealing cover 92. A connecting spring 97 is fixedly connected to the fixed slider 96. The end of the connecting spring 97 away from the fixed slider 96 is fixedly connected to the side wall of the fixed groove 95. Pulling the baffle 98 to slide to the side away from the fixed slider 96 can drive the fixed slider 96 to slide in the fixed groove 95 and compress the connecting spring 97, and finally the upper end of the baffle 98 is disconnected from the sealing cover 92, so that the sealing cover 92 can be easily taken out from the sewage outlet 91, and through the transmission of the connecting rod 93, the connecting rod 93 and the filter plate 10 can be synchronously taken out from the valve body 1 while pulling out the sealing cover 92.

[0014] Specifically, when using the present invention, first pull the baffle plate 98 to slide away from the side, thereby driving the fixed slider 96 to slide in the fixed groove 95 and compressing the connecting spring 97, finally disconnecting the upper end of the baffle plate 98 from the sealing cover 92, so that the sealing cover 92 can be easily taken out from the sewage outlet 91, and through the transmission of the connecting rod 93, while pulling out the sealing cover 92, the connecting rod 93 and the filter plate 10 can be synchronously taken out from the valve body 1, so as to facilitate the cleaning of the filter plate 10. After cleaning, the filter plate 10 is reinserted into the connecting pipe 5, and the sealing cover 92 is re-engaged in the sewage outlet 91, and then the fixing slider 96 is pushed by the connecting spring 97 to slide in the fixing groove 95, so that the baffle plate 98 can be reset, and the baffle plate 98 can be re-engaged in the lower end of the sealing cover 92, and the sealing cover 92 is fixed in the sewage outlet 91, and the cleaning of the filter plate 10 is completed, and the operation is simple and convenient.
