Problems solved by technology

[0003] There are many ways to kill Legionella pneumophila, such as chemical, ultraviolet, membrane filtration, etc., which require investment in equipment and regular maintenance; and the existence of independent closed water storage nodes in pipelines has become the main breeding ground for Legionella pneumophila, making the equipment unable to Realize the circulation and killing of the overall pipeline medium

Embodiment Construction

[0023] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] as attached figure 1 to attach Figure 4 As shown, a ball valve includes a valve body 1, a valve ball 2 and a bonnet 3; a flow column 4 is provided in the middle of the first water outlet 10 of the valve body 1 or bonnet 3; the lower end of the flow column 4 extends to the outside of the ball valve, and is provided with a water inlet 40 with one side opening; the flow column 4 is fixed to the fixed frame 5; The upper port 52 of the frame 5 extends to the edge of the valve ball 2 .

[0025] The ball valve is similar to the ball valve of the prior art, such as "a ball valve" shown in the prior art bulletin number CN208734923U, but the ball valve of the present application is used for the independent closure of the water storage node of the pipeline, and the water storage node and the pipeline supervisor Two-way circulation of the me...

Abstract

The invention belongs to the field of valve pipelines, and particularly relates to a ball valve. The ball valve comprises a valve body, a valve ball and a valve bonnet. A flow column is arranged in the middle of a first water flowing opening of the valve body or the valve bonnet. The lower end of the flow column extends out of the ball valve and is provided with a lower end water inlet with an opening at one side edge; the flow column is fixed with a fixing frame; and a fixing structure of the ball valve extends out of the outer wall of the fixing frame, a water outlet channel exists between the fixing structure and the ball valve, and an upper end opening of the fixing frame extends to the edge of the valve ball. The ball valve is installed between a independent closed water storage joint and a main pipeline, circulation flowing of internal and external media, water quality activation and bacterium breeding environment destroying are achieved through internal and external circulation double channels of the ball valve, the sanitary safety of a heating and water supply pipeline system can be effectively improved, the design is practical, and market popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of pipeline valves, in particular to a ball valve. Background technique [0002] In the heating or water supply pipeline system, some pipeline equipment such as expansion tanks or water tanks, water purifiers, etc. are located in independent closed nodes of the pipeline, with poor fluidity; water bodies that have been stored for a long time without circulation are prone to breed bacteria, or water quality deteriorates and corrodes equipment. For example, in 1976, acute febrile respiratory disease broke out in the Veterans Association in Philadelphia, causing 221 people to be infected and 34 of them died. Later research found that there was pathogenic Legionella pneumophila in the pipeline. The hydrostatic closed nodes in the pipeline system provide a production environment for the massive reproduction of Legionella pneumophila. At present, Legionella pneumophila has been detected in more than 70% of central air-condit...
