For example, in 1976, the American Feicheng refuwood military Association had outbreak of acute febrile respiratory disease causing 221 persons infected with the disease, 34 persons died, and later studies found that pathogenic legionella pneumophila existed in the pipeline. A still water closed node in a pipeline system provides a production environment for mass propagation of legionella pneumophila, and legionella pneumophila is detected in more than 70% of central air-conditioning water bodies in China at present. With the development of urban construction in China, the popularization of secondary water supply, centralized heat supply and domestic hot water centralized supply systems and air conditioning systems, the existence of legionella in a pipeline system seriously threatens the sanitary safety of life.

There are many methods for killing legionella pneumophila and the like, such as chemistry, ultraviolet, membrane filtration and the like, and equipment investment and regular maintenance are needed; the existence of the independent closed water storage nodes of the pipeline becomes a breeding place of main legionella pneumophila, so that the equipment cannot realize the circulation and killing of the medium of the whole pipeline. The method is one of the important research and development subjects in the current pipeline field for eliminating legionella bacteria and the like in a heating or water supply pipeline system and improving the water quality of the pipeline.

Detailed Description

The preferred embodiments of the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, the ball valve comprises a valve body 1, a valve ball 2 and a valve cap 3; a flow column 4 is arranged in the middle of the first water flowing port 10 of the valve body 1 or the valve cap 3; the lower end of the flow column 4 extends out of the ball valve and is provided with a water inlet 40 with an opening at one side; the flow column 4 is fixed with the fixing frame 5; the outer wall of the fixed mount 5 extends out of a fixed structure 50 of the ball valve, a water outlet channel 51 is arranged between the fixed structure 50 and the ball valve, and an upper port 52 of the fixed mount 5 extends to the edge of the ball valve 2.

The ball valve is similar to the ball valve in the prior art, such as the ball valve shown in the prior art publication No. CN208734923U, but the ball valve is used for an independent closed water storage node of a pipeline, realizes the bidirectional circulation of media between the water storage node and a pipeline main pipe, and has special application occasions. Therefore, on the circulation channel of the ball valve, a part or all of the channels are provided with a water inlet channel and a water return channel, the water inlet channel is positioned in the middle of the circulation channel in the embodiment and can deviate from the center or surround the periphery, but the structure positioned in the middle is simple to realize, and the bidirectional circulation is easier.

The core part of this application ball valve is from the pipeline is responsible for 7 and is realized not having auxiliary power and intake, the integrated configuration of flow post 4 and mount 5 promptly, and flow post 4 extends the ball valve and from the side opening intaking. The water inlet 40 is opposite to the medium flow direction of the main pipe 7, so that the medium can flow into the water inlet 40. The flowing medium of the main pipe 7 of the pipeline may be disordered, and in order to improve the water inflow, a fin-shaped guide plate 41 is arranged on the outer side of the back of the water inlet 40 of the flow column 4, and the fin-shaped guide plate 41 is completely positioned outside the ball valve and is contacted with the flowing medium of the main pipe 7 of the pipeline. The fin-shaped guide plate 41 can adjust the angle along with the flowing direction of the medium, so that the direction of the water inlet 40 is stabilized. The ball valve is attached to the main pipe 7 of the pipe, and the rotation direction of the ball valve is not constant, and the flow column 4 is fixed in the fixing frame 5 in a limited manner, but is rotatable flexibly. The limiting structures of the flow column 4 and the fixing frame 5 can be concave-convex fixing ring structures 42, movable clamp spring structures and the like.

Further, the main pipe 7 of the pipeline has different caliber specifications, the flow velocity resistance in the middle is small, the flow velocity is fast, the power is stronger, and in order to further strengthen the circulation between the water storage node and the main pipe of the pipeline, the water inlet 40 of the flow column 4 is arranged in the best position in the middle, therefore, the applicant further improves the structure: the fixing frame 5 wraps part of the flow column 4, and the flow column 4 can be fixed in the fixing frame 5 in a vertical sliding mode.

The valve ball 2 is provided with a hole-in-tube structure 20 in the middle, and the middle hole 21 of the hole-in-tube structure 20 corresponds to the upper port 52 of the fixing frame 5. The medium of the upper port 52 of the fixed frame 5 flows into the middle hole 21 of the ball valve 2 more intensively, so that the circulating path is increased, the disturbance influence of circulating water is reduced, and the circulating efficiency is improved. The outside of the middle hole 21 and the valve ball 2 are the water outlet direction of circulating water and are communicated with the water outlet channel 51. An annular groove 22 is formed in the ball valve 2 for retaining a ball retaining structure 23 extending from the bore-in-tube structure 20.

The other end corresponding to the first water flowing port 10 is a second water flowing port 11, an extension pipe 6 is fixed, the extension pipe 6 is hollow, and a water inlet and return circulation double-channel structure is formed on the inner side and the outer side of the extension pipe.

The extension pipe 6 extends to the outside of the ball valve, and the medium of the main pipe 7 of the pipeline is further pushed into the water storage node. The water flows out of the middle of the ball valve, enters the water storage node, and simultaneously extrudes media to flow into the water outlet channel 51 of the ball valve from the periphery and enter the pipeline main pipe 7, so that the internal flowing water of the whole water storage node enters a circulating state.

The outer wall of the extension tube 6 extends to form two or three steady flow ribs 60. The flow stabilizing ribs 60 reduce turbulence and accelerate backwater to enter the water outlet channel 51 in order.

The valve body 1 is also provided with a water drain valve 12 which is positioned at the central horizontal position of the valve ball 2. The water drain valve 12 can drain the medium of the water storage node for thorough cleaning.
