A new type of tear-resistant gate valve seat

Abstract

This utility model discloses a novel tear-resistant knife gate valve seat, belonging to the field of knife gate valve technology. It includes a natural rubber valve seat with a steel ring inside to enhance its rigidity. The natural rubber valve seat has a rounded corner on the side near the valve plate to enhance its tear resistance. The steel ring is circular. This utility model effectively improves the rigidity of the valve seat by using an inner steel ring structure. The steel ring is positioned close to the sealing contact surface, preferably 5-10mm from the punch size. Its length and thickness should be flexibly adjusted according to the magnitude of friction. The corner position changes from a right angle to a rounded corner, which effectively strengthens the weak point of the natural rubber valve seat, fundamentally solving the tearing problem. Furthermore, the change from a right angle to a rounded corner increases the contact area between the gate plate and the natural rubber valve seat, further improving its sealing performance.

Description

Technical Field

[0001] This utility model belongs to the field of knife gate valve technology, specifically relating to a novel tear-resistant knife gate valve seat. Background Technology

[0002] Knife gate valves are suitable for use in pipeline systems for cutting off media such as mineral slurry, coal slurry, sewage, and clean water. Their cutting-off function is achieved by raising and lowering a stainless steel gate. During the raising and lowering of the gate, the rubber valve seat inside the valve body plays a sealing role, ensuring no leakage when fully open or fully closed. However, during the raising and lowering process, especially during the lowering of the gate, friction is generated when it comes into contact with the rubber valve seat. In severe cases, this can cause local tearing of the valve seat, resulting in damage and greatly shortening the service life of the valve. Utility Model Content

[0003] The purpose of this invention is to provide a novel anti-tear gate valve seat, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel tear-resistant knife gate valve seat includes a natural rubber valve seat, wherein the inner cavity of the natural rubber valve seat is provided with a steel ring for improving its rigidity.

[0006] The natural rubber valve seat has a rounded corner on the side near the valve plate to enhance its tear resistance.

[0007] In a preferred embodiment of this utility model, the steel ring is circular in shape.

[0008] As a preferred embodiment of this utility model, the steel ring is made of stainless steel. By setting the steel ring, the rigidity of the natural rubber valve seat can be improved, and the tear resistance of the natural rubber valve seat can be enhanced.

[0009] As a preferred embodiment of this utility model, the natural rubber valve seat has an installation hole on its left side.

[0010] In a preferred embodiment of this invention, the diameter of the steel ring is larger than the diameter of the inner cavity of the natural rubber valve seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by adopting an inner steel ring structure, the rigidity of the valve seat can be effectively improved. The position of the steel ring should be close to the sealing contact surface, preferably 5-10mm away from the punch size, and its length and thickness should be flexibly adjusted according to the magnitude of the friction force.

[0012] The corner position is changed from a right angle to a rounded corner, which is equivalent to strengthening the weak point of the natural rubber valve seat and fundamentally solving the tearing problem. On the other hand, changing from a right angle to a rounded corner is equivalent to increasing the contact area between the gate and the natural rubber valve seat, further improving its sealing performance.

[0013] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Wherein:

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example

[0021] Reference Figure 1-2 This is the first embodiment of the present utility model. This embodiment provides a novel anti-tear gate valve seat, including a natural rubber valve seat 100, and a steel ring 110 for improving its rigidity is provided in the inner cavity of the natural rubber valve seat 100.

[0022] The natural rubber valve seat 100 has a rounded corner on the side near the valve plate to enhance its tear resistance.

[0023] Specifically, the steel ring 110 is circular in shape;

[0024] Furthermore, the steel rim 110 is made of stainless steel;

[0025] Preferably, the natural rubber valve seat 100 has a mounting hole on its left side;

[0026] It should be noted that the diameter of the steel ring 110 is larger than the diameter of the inner cavity of the natural rubber valve seat 100;

[0027] When in use, the working principle of the above structure is that by adopting the inner steel ring 110 structure, the rigidity of the valve seat can be effectively improved. The position of the steel ring 110 should be close to the sealing contact surface, preferably 5-10mm away from the punch size, and its length and thickness should be flexibly adjusted according to the magnitude of friction.

[0028] In summary, the beneficial effects of the above structure are that the corner position is changed from a right angle to a rounded corner, which is equivalent to strengthening the weak point of the natural rubber valve seat 100 and fundamentally solving the tearing problem. On the other hand, changing from a right angle to a rounded corner is equivalent to increasing the contact area between the gate and the natural rubber valve seat 100, further improving its sealing performance.

[0029] The steel ring 110 can improve the rigidity of the natural rubber valve seat 100 and enhance its tear resistance.

[0030] By using rounded corners, the weak points of the natural rubber valve seat 100 are strengthened, fundamentally solving the tearing problem. Furthermore, the change from right angles to rounded corners increases the contact area between the gate and the natural rubber valve seat 100, further improving its sealing performance.

[0031] The mounting holes facilitate the secure installation of the natural rubber valve seat 100.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
