AI Technical Summary
Due to the angle between the gate plates, traditional gate valves are susceptible to lateral pressure of the water flow, resulting in insufficient stability and may cause water leakage.
A new type of gate valve is designed, using two gate plates arranged symmetrically, with an angle between the gate plates, and a blocking cup formed integrally in the middle of the gate plate, with the opening of the blocking cup pointing to the outside. At the same time, when the gate plate is lifted and lowered, the limiting position is limited by the coordination between the limiting strip and the limiting side plate, and a seal is provided between the lifting shell and the cover to enhance the sealing property.
By combining the gate plate with the inclined angle and the flow blocking cup, the lateral pressure of the gate plate is slowed down due to inclination, the stability and sealing of the gate valve are improved, and water leakage is avoided.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of gate valves, and particularly relates to a new type of gate valve. Background Art
[0002] A gate valve is a closing member, i.e., a gate plate. The moving direction of the gate plate is perpendicular to the fluid direction. A gate valve can only be fully opened and fully closed, and cannot be used for regulation and throttling. The gate valve is sealed by the contact between the valve seat and the gate plate.
[0003] When a traditional gate valve is in use, since there is a certain angle between the two gate pieces, the gate pieces with an angle are prone to being subjected to the lateral pressure of the water flow inside the valve, resulting in the problem that the gate pieces are deflected due to the water pressure, and it is easy to cause the problem of water leakage of the gate valve due to insufficient stability. Content of the Utility Model
[0004] To solve the problems raised in the above background art, the utility model provides a new type of gate valve.
[0005] To achieve the above object, the utility model provides the following technical solution: A new type of gate valve includes a housing, and a lifting housing integrally formed on the upper part of the housing. A cover is installed at the upper opening end of the lifting housing, and positioning bolts for fixing are provided between the lifting housing and the cover. A gate plate is installed inside the housing. A gate rod is fixed to the upper part of the gate plate. A reduction sleeve is screwed on the outside of the gate rod, and a turntable is fixed to the upper end of the reduction sleeve. The reduction sleeve is rotatably installed at the upper end of the cover. The two gate plates are symmetrically arranged, and there is an angle between the two gate plates. A flow blocking cup is integrally formed in the middle of the gate plate, and the openings of the flow blocking cups in the middle of the two gate plates both point outward. A limiting side plate is provided on the side of the gate plate. A limiting strip is integrally formed at the connection between the housing and the lifting housing, and the limiting strip is used to limit the limiting side plate. A sealing member is provided between the lifting housing and the cover.
[0006] As a preferred technical solution of the new type of gate valve of the utility model, the sealing member includes a sealing rubber ring provided between the lifting housing and the cover. Sealing convex rings are integrally formed on the upper and lower surfaces of the sealing rubber ring. Grooves matching with the sealing convex rings are opened at the upper end of the lifting housing and the lower end of the cover, and the sealing convex rings are installed in the grooves.
[0007] As a preferred technical solution of the new type of gate valve of the utility model, a first sealing ring is installed in a groove opened at the edge of the gate plate, and a second sealing ring is installed in a groove opened inside the housing, and the second sealing ring is located on the side of the first sealing ring.
[0008] As a preferred technical solution of the new type of gate valve of the utility model, both the first sealing ring and the second sealing ring are provided with two.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0010] 1. By means of two symmetrically arranged brake pads with an included angle between them, it is convenient for the two brake pads with the included angle to be sealed with the housing when descending, thus realizing the opening and closing function of the gate valve. The flow-blocking cups are integrally formed in the middle of the brake pads, and the openings of the flow-blocking cups in the middle of the two brake pads both point outward. Therefore, when the brake pads are subjected to water flow, the impact of the water flow on the flow-blocking cups can slow down the lateral pressure of the water flow on the brake pads due to the inclination. When the brake pads are lifted and lowered, they are also limited by the cooperation of the limiting strips and the limiting side plates, which increases the stability of the brake pads during lifting and lowering. The sealing member arranged between the lifting housing and the cover facilitates the sealing of the lifting housing and the cover by the sealing member after being fixed by the positioning bolts.
[0011] 2. The sealing member is composed of a sealing rubber ring and a sealing convex ring. The sealing convex ring is integrally formed on the upper and lower surfaces of the sealing rubber ring, and the sealing convex ring is installed in the sealing convex rings opened at the upper end of the lifting housing and the lower end of the cover, so that the sealing rubber ring and the sealing convex ring cooperate to seal the connection between the lifting housing and the cover.
[0012] 3. Through the first sealing ring installed in the groove opened at the edge of the brake pad and the second sealing ring installed in the groove opened in the housing, when the brake pad is located inside the housing, the first sealing ring and the second sealing ring cooperate for sealing. Both the first sealing ring and the second sealing ring are provided with two, which facilitates the two brake pads to be sealed with the housing through the two first sealing rings and the two second sealing rings.
