Description

Technical Field

[0001] The utility model relates to the technical field of check valves, in particular to a novel groove check valve. Background Art

[0002] A check valve is a valve with a circular disc as the opening and closing part. It blocks the backflow of the medium by its own weight and the pressure of the medium. It is an automatic valve and is also called a non-return valve, one-way valve, reflux valve or isolation valve. The disc movement mode is divided into lifting type and swing type.

[0003] In application number: CN202123321944.3, a grooved check valve is disclosed, which seals the gap between the entire mounting shaft and the rocker arm through a mounting box, a flexible cover and an extension, thereby avoiding wear between the mounting shaft and the rocker arm caused by contact between impurities in the water and the gap, ensuring that the rocker arm is in the same position each time it is opened and closed, thereby ensuring the sealing effect when the valve plate is closed, and the use of a flexible cover can compensate for the movement of the rocker arm during the rotation process. However, the above design still has shortcomings. The structures at both ends of the grooved check valve are simple, and the check valve does not have a filtering function, thereby reducing its practicality.

[0004] To this end, we propose a new groove check valve. Utility Model Content

[0005] The main purpose of the utility model is to provide a new groove check valve. Through the design of the filter component, the valve body has a filtering function. When the liquid enters the valve body, it first passes through the filter screen, thereby achieving the purpose of filtering, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A new groove check valve comprises a valve body and a flange, wherein flanges are provided at both ends of the valve body, and a groove for installing a filter assembly is provided at one end of the flange away from the valve body, and a threaded groove is provided on the inner wall of the groove. The filter assembly comprises a filter screen, a mounting piece, a rubber pad, a bolt, a clamp and a sealing pad; a mounting groove for installing the filter screen is provided in the mounting piece, the clamp is a circular ring structure, and the filter screen is a circular plate structure, and the clamp is fixedly sleeved on the outside of the filter screen.

[0008] By adopting the above technical solution and designing the filter assembly, the valve body is provided with a filtering function. When liquid enters the valve body, it first passes through the filter screen, thereby achieving the purpose of filtering.

[0009] Specifically, a clamping groove matched with the mounting piece is provided on the outer edge of one side of the clamping piece close to the valve body.

[0010] Specifically, the clamping piece is clamped with the mounting piece, and one end of the bolt passes through the clamping piece and is threadedly connected with the mounting piece.

[0011] Specifically, a sealing gasket is sleeved on the outer side of the clamp, and the sealing gasket is a circular ring structure.

[0012] Specifically, a rubber pad with a circular ring structure is fixedly glued to one end of the mounting piece away from the flange.

[0013] Specifically, a matching groove matched with the thread groove is provided on the outer side of the mounting piece, and the mounting piece is threadedly connected to the flange.

[0014] Beneficial effects of the utility model:

[0015] 1. The novel groove check valve described in the utility model is convenient for installing the filter assembly as a whole through the design of the groove and the thread groove. The mounting piece is threadedly connected to the flange, which facilitates the installation and removal of the mounting piece, so that the filter assembly can be used flexibly;

[0016] 2. The novel groove check valve described in the utility model has a filtering function in the valve body through the design of the filtering component. When the liquid enters the valve body, it first passes through the filter screen plate, thereby achieving the purpose of filtering, thereby improving its practicality.
