Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a two-piece ceramic ball check valve. Background Technology

[0002] A check valve, also known as a one-way valve or non-return valve, is a type of automatic control valve. Its core function is to allow the medium (liquid, gas, or fluid containing particles) to flow in only one direction along the pipeline. When the medium attempts to flow in the opposite direction due to system pressure changes or other reasons, the valve automatically closes using the medium's own kinetic energy or pressure difference, thus blocking the backflow path. However, when the fluid being transported contains a medium with high hardness, existing ordinary check valves are not very suitable because long-term use will lead to severe wear within the valve body, significantly shortening the valve's service life. Utility Model Content

[0003] This invention provides a two-piece ceramic ball check valve, which aims to solve the technical problem that existing check valves suffer severe wear and shortened valve life when used in media with high hardness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a two-piece ceramic ball check valve, comprising a valve body and a ceramic liner, wherein the valve body comprises two symmetrically arranged sleeves connected by bolts, the ceramic liner comprises a guide sleeve in the middle section, one end of the guide sleeve is provided with a fixed sleeve and the other end is provided with a through sleeve, the inner sidewall of the through sleeve is provided with several first grooves, and a movable ceramic ball is disposed inside the guide sleeve.

[0005] Furthermore, the end of the through sleeve facing the guide sleeve is funnel-shaped.

[0006] Furthermore, the inner wall of the guide sleeve facing the through sleeve has several second grooves.

[0007] Furthermore, the inner ring diameter of the fixing sleeve is smaller than the diameter of the ceramic sphere.

[0008] Furthermore, flanges are provided at both ends of the sleeve, the two flanges are pressed together and the two sleeves are locked together with bolts, and the flanges at the other two ends are used to connect to the pipeline.

[0009] Furthermore, sealing rings are provided between the guide sleeve, the fixing sleeve, and the through sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model discloses a two-piece ceramic ball check valve with a simple and ingenious design. It includes a valve body and a ceramic liner. The valve body comprises two symmetrically arranged sleeves connected by bolts. The ceramic liner includes a guide sleeve in the middle section. One end of the guide sleeve has a fixed sleeve, and the other end has a through sleeve. The inner wall of the through sleeve has several first grooves. A movable ceramic ball is placed inside the guide sleeve. Forward-flowing fluid enters the guide sleeve from the fixed sleeve. Under the pressure of the fluid, the ceramic ball is pushed towards the through sleeve and abuts against it. The fluid then passes through the first grooves on the inner wall of the through sleeve. Conversely, reverse-flowing fluid enters the guide sleeve from the through sleeve and pushes the ceramic ball towards the fixed sleeve. The ceramic ball blocks the fixed sleeve, thus preventing fluid flow. The ceramic liner also prevents wear caused by high-hardness media in the fluid, improving the valve's service life.

[0022] Example

[0023] Reference Figure 1-3 As shown, this utility model discloses a two-piece ceramic ball check valve, including a valve body 10 and a ceramic liner 20. The ceramic liner 20 is disposed inside the valve body 10 to prevent wear. The valve body 10 includes two symmetrically arranged sleeves, which are connected by bolts. In this embodiment, flanges are provided at both ends of the sleeves. The two flanges are pressed together and locked with bolts. The flanges at the other two ends are used to connect to the pipeline. The bolted connection between the two sleeves facilitates the disassembly and replacement of the internal ceramic liner 20, and the flanges at both ends facilitate the installation of the check valve.

[0024] Reference Figure 1-3 As shown, the ceramic liner 20 includes a guide sleeve 203 in the middle section. A movable ceramic ball 201 is disposed inside the guide sleeve 203. A fixed sleeve 202 is disposed at one end of the guide sleeve 203, and a through sleeve 204 is disposed at the other end. Several first grooves 2041 are opened on the inner side wall of the through sleeve 204. Specifically, the fluid enters the guide sleeve 203 from the fixed sleeve 202 end. The fluid drives the ceramic ball 201 to stick tightly to the through sleeve 204. Since the first grooves 2041 are opened on the side wall of the through sleeve 204, the fluid can flow through the first grooves 2041. Moreover, the end of the through sleeve 204 facing the guide sleeve 203 is funnel-shaped. The fluid pushes the ceramic ball 201 in the funnel-shaped through sleeve 204, preventing the ceramic ball 201 from moving during the fluid flow and causing the fluid to become unstable. When the fluid passes through the through sleeve 204 and enters the guide sleeve 203, it pushes the ceramic ball 201 toward one end of the fixed sleeve 202. Since the inner ring diameter of the fixed sleeve 202 is smaller than the diameter of the ceramic ball 201, the fluid pushes the ceramic ball 201 to block the fixed sleeve 202, preventing the fluid from passing through and thus preventing the fluid from flowing back.

[0025] Reference Figure 1-3 As shown, the inner wall of the guide sleeve 203 facing the through sleeve 204 has several second grooves 2031. The second grooves 2031 are aligned with the first grooves 2041. When the fluid enters the guide sleeve 203 from the fixed sleeve 202, the second grooves 2031 can further expand the space for fluid flow, so that the fluid can quickly enter the through sleeve 204 from the guide sleeve 203, achieving the effect of a large amount of fluid passing through.

[0026] Reference Figure 1-3 As shown, sealing rings 205 are provided between the guide sleeve 203 and the fixed sleeve 202 and the through sleeve 204. The sealing rings 205 are used to seal the gaps between the guide sleeve 203 and the fixed sleeve 202 and the through sleeve 204 to prevent fluid from seeping into the valve body 10 from the connection and causing damage to the valve body 10.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
