Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a valve sealing plate, which has the advantages of reducing the resistance when the gate valve is closed and reducing the wear on the sealing ring when the sealing plate moves, and solves the problem that the staff or firefighters cannot completely close the gate valve with their own strength. When the gate valve and the sealing plate move, the sealing ring is rubbed and squeezed, causing great wear and tear on it

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] see Figure 1-7 , the valve sealing plate, including the valve body 1, the side of the inner wall of the valve body 1 is welded with a strut 10, and the end of the strut 10 away from the valve body 1 is fixedly installed with a push plate 11, and the push plate 11 is in the shape of a slope, and the push plate 11 is used Squeeze the valve plate 19 to seal the sealing ring 28, which can reduce the friction of the valve plate 19 on the sealing ring 28. On...

Abstract

The invention relates to the technical field of valve sealing parts, and discloses a valve sealing plate. The valve sealing plate comprises a valve body, wherein a water discharging groove is formed in one side of the valve body, a sleeve is embedded in the other side of the valve body, a water discharging pipe is welded to the side face of the valve body, and the position of the water discharging pipe corresponds to the position of the water discharging groove; and the inner wall of the sleeve is in threaded connection with a water admission pipe, a connecting part is arranged in the valve body, and a valve plate is arranged in the connecting part. According to the valve sealing plate, by arranging a guide block and a baffle, when a gate valve is closed, water flow moves downwards along with the valve plate to gradually increase the pressure when the gate valve is closed, the pressure of the water flow can be effectively reduced by forming a through groove in the surface of the valve plate, and then the guide block makes contact with the bottom of the inner wall of the valve body along with movement of the valve plate, so that the resistance of water flow when the gate valve is closed is effectively reduced, and a worker or a firefighter can close the gate valve conveniently.

Description

technical field [0001] The invention relates to the technical field of valve sealing components, in particular to a valve sealing plate. Background technique [0002] A valve is a pipeline accessory that controls the flow of gas or liquid in a pipeline. According to its different functions, it can be divided into many different types of valves. As the main blocking component in the valve, the sealing plate is particularly important for its function and material. Important, a good sealing plate can often determine the service life of the valve. [0003] According to the different types of valves, the sealing plate is also divided into various shapes, among which it is mainly divided into three types: gate valve sealing plate, butterfly valve sealing plate and ball valve sealing plate. The main thing is to use the gate valve sealing plate to control the flow rate, but because the flow rate of the main water flow is too fast, the gate valve sealing plate will be pressurized ac...
