Description
Technical Field
The utility model belongs to the technical field of the valve, specifically indicate a novel five eccentric butterfly valves.
Background
A butterfly valve, also called a flap valve, is a regulating valve with a simple structure, and can be used for on-off control of low-pressure pipeline media, namely a valve with a closing part (a valve clack or a butterfly plate) which is a disc and rotates around a valve shaft to open and close, and the valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. The butterfly valve can be divided into a first eccentric butterfly valve, a second eccentric butterfly valve, a third eccentric butterfly valve, a fourth eccentric butterfly valve and a fifth eccentric butterfly valve according to different use scenes, and the fifth eccentric butterfly valve is an advanced butterfly valve at present, and has the characteristics of high opening and closing speed and good fluid control property. However, the conventional butterfly valve seal is easily damaged under long-term fluid impact, and a vortex is easily formed on the back of the butterfly valve in the fluid direction, so that the butterfly valve plate is eroded, the butterfly valve plate is damaged, and the pipe resistance is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a sealing performance is good, reduce the erosion phenomenon, alleviate the novel five eccentric butterfly valves that the pipe hinders.
In order to realize the above functions, the utility model discloses the technical scheme who takes as follows: the utility model provides a novel five eccentric butterfly valves, includes valve body, valve plate, valve rod, seal receptacle, closing plate and fluid control board, the valve plate is oval frustum shape setting, the valve rod is located on the valve plate and the valve rod is rotatable to be located on the valve body inner wall, the seal receptacle is located on the valve body inner wall, the closing plate is located on the seal receptacle, the fluid control board is located on the valve body inner wall, the fluid control board is located one side of valve plate dorsad fluid direction.
Further, the sealing plate is an elastic metal plate.
Furthermore, a plurality of groups of holes are uniformly formed in the fluid control plate.
Further, the valve plate can only be opened in one direction towards the fluid direction of the valve body.
The utility model adopts the above structure to gain beneficial effect as follows: the utility model provides a pair of novel five eccentric butterfly valves can alleviate the fluid to the erosion of valve plate through setting up the fluid control board, prolong the life of valve plate, and five eccentric butterfly valves have and open and close fastly, and have the characteristics of good fluid control characteristic.
