Problems solved by technology

Since the valve is at the node position of the fluid, because the position of the valve is very easy to hide dirt, over time, the valve may cause pollution to the fluid, especially for drinking water with high cleanliness requirements. This is something we cannot ignore and expect to solve The problem

Embodiment Construction

[0016] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0017] see figure 1 , a self-cleaning valve of the present invention, comprising: a valve body 2 with a valve cavity 1 formed inside, an adapter pipe fixedly connected to the valve body 2, a valve handle 3 and a valve stem 4 integrally formed with the valve handle 3 . Among them, the valve chamber 1 is provided with a central column 5 formed with an internal thread that cooperates with the valve stem 4, and an external thread is formed above the middle of the valve stem 4 (not shown in the figure), and the valve handle 3 drives the valve stem 4 to face each other. Rotate the central column 5 to switch between the open and closed states of the valve. Inevitably, a through hole for the valve rod 4 to extend is formed on the adapter pipe, and when the valve rod 4 is completely inserted into the through hole, it is in the position figure 1 ...

Abstract

The invention discloses a self-cleaning valve, comprising a valve body, an adapting pipe, a valve handle and a valve rod, wherein a valve cavity is formed in the valve body; the adapting pipe and the valve handle are fixedly connected with the valve body; the valve handle and the valve rod are integrally formed. The self-cleaning valve is novel and ingenious in structural design; an activated carbon adsorption layer is adhered to the valve rod, so that pollutants in fluid are effectively absorbed; the pollutants are decomposed timely through a photocatalytic effect of an ultraviolet lamp, so that filth, which is easily generated after the valve body is used for a long time, is prevented; moreover, a flowing plate is arranged in the adapting pipe; flowing holes of the flowing plate are of a horn shape which is gradually smaller in size along a direction of the fluid, so that the fluid can burst into the valve body and flush the attachments on the pipe wall, therefore the pollutants are prevented from being adhered to the pipe wall.

Description

technical field [0001] The invention relates to a valve, in particular to a self-cleaning valve. Background technique [0002] The valve is a component used to control the opening and closing of the fluid and the flow rate. It is generally composed of a valve body, a valve stem and a valve core forming a valve cavity inside. The valve stem drives the valve core to rotate, drives the opening and closing of the valve and adjusts the opening size. Since the valve is at the node position of the fluid, because the position of the valve is very easy to hide dirt, over time, the valve may cause pollution to the fluid, especially for drinking water with high cleanliness requirements. This is something we cannot ignore and expect to solve The problem. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a valve capable of self-cleaning and minimizing pollution. [0004] In order to achieve the ab...
