Abstract

The invention discloses a closed butterfly valve capable of controlling flow. The closed butterfly valve comprises a mounting pipe and a mounting plate. A first connecting pipe is arranged at one endof the mounting pipe. A second connecting pipe is connected to the first connecting pipe. Fixed pipes are arranged at the top end of the first connecting pipe and the top end of the second connectingpipe. A sliding groove is formed in each fixed pipe. A sliding block is rotationally connected in each sliding groove. The bottom end of each sliding block is connected with a connecting shaft. The connecting shafts penetrate through and extend into the first connecting pipe and the second connecting pipe and are connected with baffles. According to the closed butterfly valve capable of controlling the flow, connection of the first connecting pipe and the second connecting pipe is closed in multiple connecting manners, and therefore it is guaranteed that the closed butterfly valve overall hasgood sealing performance, and leakage can be effectively avoided; meanwhile, air inflation and air deflation are carried out in an air bag, and therefore the size of the air bag is changed; and thus,the outflow volume in the mounting pipe is controlled, and therefore a user can adjust the flow conveniently according to the use requirements.

Description

technical field [0001] The invention relates to the technical field of closed butterfly valves, in particular to a closed butterfly valve capable of controlling flow. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. A kind of valve, there are many butterfly valves on the market at present, but due to the design reasons, there are problems of poor airtightness and easy leakage, and there are also problems that it is not convenient to control the flow, so that it is not easy to Can meet people's needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a closed butterfly valve that can control the flow rate, which has good sealing performance and is convenient to control the flow rate according to the needs of use, so as to meet people's use needs...
