Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a filter butterfly valve that facilitates cleaning includes a valve body 1, a pipe 2, a drain pipe 3, a filter mechanism 4, and an opening and closing mechanism 5. The left and right ends of the pipe 2 are provided with a valve body 1, and the center of the bottom of the pipe 2 is provided with There is a drain pipe 3, a filtering mechanism 4 is arranged inside the two valve bodies 1, and an opening and closing mechanism 5 is arranged on the top of the two valve bodies 1, and the opening and closing mechanism 5 cooperates with the filtering mechanism 4.

[0030] The filter mechanism 4 includes a rotating shaft 41, a fan-shaped filter screen cover 42 and a fan-shaped valve cover 44. The tops of the two valve bodies 1 are rotatably provided with a rotating shaft 41, and the rotating shaft 41 is located in the valve body 1 and is symmetrically provided with a fan-shaped filter screen. The cover 42 and the f...

Embodiment 2

[0035] Such as Figure 5 , Figure 6 and Figure 7As shown, on the basis of Embodiment 1, a filter butterfly valve that is beneficial to cleaning also includes a pulley 17, a flat belt 18, a support frame 19, a fixed plate 20 and a protective housing 21, and the rear ends of the two rotating shafts 52 are provided There is a pulley 17, a flat belt 18 is arranged between the two pulleys 17, a support frame 19 is arranged on the two valve bodies 1, a fixed plate 20 is arranged on the two support frames 19, and a protective shell is arranged on the fixed plate 20 21 , the pulley 17 and the flat belt 18 are located in the protective casing 21 . By turning the rotating handle 55 on one side, the belt pulley 17 can be driven to rotate, and then the rotating handle 55 on the other side can be driven to rotate through the flat belt 18, so as to realize synchronous rotation and facilitate operation.

[0036] It also includes oblique deflectors 22 . The inner bottom of the pipeline 2...

Abstract

The invention discloses a filtering butterfly valve beneficial to cleaning. The filtering butterfly valve comprises valve bodies, a pipeline, a drainage pipe, filtering mechanisms and opening-closingmechanisms, wherein the valve bodies are arranged at the two ends of the pipeline; the drainage pipe is arranged in the center of the bottom of the pipeline; the filtering mechanisms are arranged in the two valve bodies; the opening-closing mechanisms are arranged at the tops of the two valve bodies correspondingly; and the opening-closing mechanisms are matched with the filtering mechanisms. According to the filtering butterfly valve, synchronous rotation of a fan-shaped filter screen cover and a fan-shaped valve cover is achieved by rotating a rotating handle, and meanwhile the opening and closing of a fan-shaped sleeve plate and a fan-shaped plate are achieved to facilitate discharging of impurity garbage; an inclined flow guide plate can realize that water flow drives the impurity garbage to flow towards the drainage pipe, so that the impurity garbage can be discharged conveniently; a worker grasps a pull rod to move in a reciprocating way, a piston moves in a reciprocating way ina cylinder block, water is pumped into the cylinder block through a three-way liquid inlet pipe, and then the water is sprayed onto the fan-shaped filter screen cover through spraying pipes so as to flush impurities adhering to the fan-shaped filter screen cover.

Description

technical field [0001] The invention relates to a butterfly valve, in particular to a filter butterfly valve which is beneficial to cleaning. Background technique [0002] The butterfly valve mainly includes a valve body, a valve stem, a valve plate and a handle. It refers to a valve in which the working plate is a disc and revolves around the axis of rotation to achieve opening and closing. Valves can be used to control the flow of various types of fluids such as water, air, steam, various corrosive media, mud, liquid metal and radioactive media, and mainly play the role of cutting and throttling on the pipeline. [0003] However, when the valve body of the butterfly valve has too much impurities and garbage, it will cause the butterfly valve to be opened with difficulty, and the pipeline will be blocked. [0004] Therefore, it is necessary to design a filter butterfly valve that can play a filtering role and facilitate cleaning of impurities, so as to solve the above prob...
