Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] like figure 1 , a wedge gate valve, including a valve body 1, a valve seat 2, a wedge gate 3, a valve cover 4, a valve stem 5, the stuffing box part 6 of the valve cover 4 is welded on the valve cover 4 with a bushing 7, and the upper The sealing seat 8 is threaded on the bushing 7 .

[0019] The water inlet of the valve body 1 is connected with a filter tube and a connection port whose inner diameter is larger than the outer diameter of the filter tube. The filter tube is located in the inner cavity of the connection port. After the connection port is connected with the external pipeline, the water flow enters the valve stator through the filter tube. liquid inflow port.

[0020] like figure 2 and 3 , the filter tube has a pipe body with an outer end blocked, the outer wall of the pipe body has an outer spiral groove with the pipe body as a guide...

Abstract

The invention discloses a wedge gate valve. The wedge gate valve comprises a valve body, a valve base, a wedge gate plate, a valve cover and a valve rod. The stuffing box part of the valve cover is welded to the valve cover through a lining, and an upper sealing base is connected to the lining through threads. The wedge gate valve is reasonable in structure, and the upper sealing base is convenient to replace and good in sealing performance; furthermore, the wedge gate valve has the filtering function, and a valve element is not damaged easily.

Description

technical field [0001] The invention relates to a valve, in particular to a wedge gate valve. Background technique [0002] In the existing gate valve, it is troublesome to replace the upper sealing seat, and the sealing performance is not satisfactory. Moreover, the existing valve does not have a filtering function, and the valve core is easily damaged. Contents of the invention [0003] The purpose of the present invention is to provide a gear drive wedge gate valve with reasonable structure, easy replacement of the upper sealing seat, good sealing performance and integrated filtering function. [0004] Technical scheme of the present invention is as follows: [0005] A wedge gate valve includes a valve body, a valve seat, a wedge gate, a valve cover, and a valve stem. The stuffing box of the valve cover is welded to the valve cover with a bushing, and the upper sealing seat is connected to the bushing with threads; [0006] The water inlet of the valve body is connec...
