The invention discloses a V-shaped knife gate valve with a wide-area flow regulation characteristic. The V-shaped knife gate valve with the wide-area flow regulation characteristic comprises a valve body, a middle cavity sealing ring and a V-shaped flow channel. The V-shaped flow channel is formed in the valve body. A damper is mounted in the valve body. A U-shaped sealing strip is fixedly connected into the valve body. The middle cavity sealing ring is arranged in the valve body, and the top of the middle cavity sealing ring is fixedly connected with a packing gland. According to the V-shapedknife gate valve with the wide-area flow regulation characteristic, the flow channel in the knife gate valve is optimized, so that the problem of poor performance of traditional knife gate valves inuse is solved; a circular flow channel of the traditional knife gate valve is optimized into the V-shaped flow channel, so that an accurate aeration rate under the requirement of a micro amount of gasis achieved, the production cost is greatly reduced for sewage plants, and the purpose of improving the water quality is improved; and the V-shaped knife gate valve with the wide-area flow regulationcharacteristic is simple in overall structure, very convenient to operate and high in practicability and has the characteristic of accurate flow control within a wider area.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a V-shaped knife gate valve with wide-area flow regulation characteristics. Background technique [0002] With the development of science and technology and social progress, human life and production also produce a large amount of sewage. Therefore, more and more sewage treatment plants are put into operation to purify water quality and promote the environmental protection process of human society. The precise gas explosion system of sewage treatment plants is right Biological treatment of sewage is a very important step in improving water quality. [0003] Now the sewage treatment plant widely adopts the traditional circular channel knife gate valve as the precise gas explosion control valve to control the aeration volume, but because the traditional knife gate valve can only provide precise adjustment of the air volume, due to the general small opening air volume characteristics...
