Description

Technical Field

[0001] The present invention relates to the technical field of valves, and specifically to a combined butterfly valve. Background Art

[0002] A butterfly valve refers to a valve that is often used on water pipelines to control the opening and closing of the pipeline. Valves are usually used to control the transmission of liquid and gaseous substances such as water and gas, and can play a role in switching control of the transmission work, so as to achieve the functions of opening and closing and regulation. During the installation of the butterfly valve, in order to maintain the horizontal stability of the butterfly valve installation, a combined base is usually installed on the butterfly valve to increase the grounding height of the butterfly valve and facilitate connection with the pipeline.

[0003] In the prior art, when the butterfly valve is in use, it usually plays the role of opening and closing and regulating the water pipeline. When the butterfly valve is closed, the water body is blocked by the butterfly valve, making it easy for impurities in the water body to precipitate and accumulate near the butterfly valve due to the static water body. Thus, when the butterfly valve is opened and regulated, the adjustment resistance of the butterfly valve rotation increases, affecting the working efficiency during the adjustment of the butterfly valve. Summary of the Invention

By setting a water bottom impact device, during the adjustment of the butterfly valve, the top of the T-shaped top plate 43 can squeeze the water flow in the T-shaped water storage box 42 to the outside. The water flow can generate a water flow impact to the outside through the round hole 44 of the T-shaped water storage box 42, thereby driving the water flow stirring at the bottom of the pipe body 1 to disperse the sediment and improving the smoothness during the adjustment of the butterfly valve;

By setting a water flow diversion device, during the process of the T-shaped top plate 43 being pushed upward by the trapezoidal rod 41, the T-shaped top plate 43 will push the L-shaped connecting rod 51 upward, and the L-shaped connecting rod 51 can drive the flow dividing plate 53 to rotate and expand into an angular shape through the rotating rod 52, guiding the water flow to the center and edge of the pipe body 1, improving the stirring effect at the center and the scouring effect of the water flow on the pipe wall;

[0029] An auxiliary agitation device is provided on the T-shaped water storage box 42. The auxiliary agitation device includes a spring rod 71. One end of the spring rod 71 is rotatably installed on the outer wall of the top of the T-shaped top plate 43, and the other end of the spring rod 71 is rotatably installed on the outer wall of the arc-shaped plate 72. The spring rod 71 passes through and is slidably installed on the T-shaped water storage box 42. A semi-circular convex block 73 is fixedly installed on the outer wall of the arc-shaped plate 72. A knocking rod 74 is rotatably installed on the outer wall of one end of the L-shaped connecting rod 51 close to the arc-shaped plate 72. The bottom end of the knocking rod 74 close to the arc-shaped plate 72 is arc-shaped. An elastic element is provided between the outer wall of the knocking rod 74 and the outer wall of the L-shaped connecting rod 51. A through hole 75 is formed in the arc-shaped plate 72. By providing the auxiliary agitation device, during the upward movement of the T-shaped top plate 43, the T-shaped top plate 43 pushes the spring rod 71 to move outward, and the spring rod 71 can then push the arc-shaped plate 72 to slide outward. The friction vibration between the arc-shaped plate 72 and the knocking rod 74 through the semi-circular convex block 73 promotes the falling of impurities on its outer wall. At the same time, the arc-shaped plate 72 can perform an auxiliary agitation operation on the water quality precipitation at the bottom of the pipe body 1 through the through hole 75.

[0030] The working process of the present invention is as follows. During the adjustment of the butterfly valve, the staff can drive the adjustment rod 3 to rotate to adjust the butterfly valve. The rotation of the adjustment rod 3 can drive the trapezoidal rod 41 to rotate accordingly. During the rotation of the trapezoidal rod 41, it can jack up the bottom of the T-shaped top plate 43 through its trapezoidal inclined surface. The top of the T-shaped top plate 43 can then squeeze the water flow in the T-shaped water storage box 42 outward. The water flow can generate a water flow impact outward through the round hole 44 of the T-shaped water storage box 42. When the bottom of the T-shaped top plate 43 is separated from the trapezoidal rod 41, the T-shaped top plate 43 will return to its initial position downward due to the elastic force of the elastic element. Finally, the T-shaped top plate 43 can move up and down reciprocally under the impact of the trapezoidal rod 41, thereby driving the agitation of the water flow at the bottom of the pipe body 1 to disperse the sediment and improving the smoothness during the adjustment of the butterfly valve.

[0031] By providing a water flow diversion device, when the T-shaped top plate 43 is squeezed upward by the trapezoidal rod 41, the T-shaped top plate 43 will push the L-shaped connecting rod 51 upward, and the L-shaped connecting rod 51 can drive the rotating rod 52 to rotate upward. The upward rotation of the rotating rod 52 can expand the diverter plate 53 to form an angle, and the angle of the diverter plate 53 can divert the water flow to the center and edge of the pipe body 1. The water flow to the center of the pipe body 1 can improve the stirring effect at the center of the pipe body 1, and the water flow to the edge can improve the flushing effect of the water flow on the pipe wall, thereby In order to achieve the automatic cleaning effect of the pipe wall, the elastic sliding device is provided. When the diverter plate 53 is opened, the water flows through the diverter plate 53 to drive the sleeve rod 61 to slide, and the sleeve rod 61 can reduce the distance between itself and the rotating column 64. The sliding of the sleeve rod 61 can make the push rod 63 rotate, and the rotation of the push rod 63 can drive the slider 62 to slide. The sliding of the sleeve rod 61 can scrape off the impurities on the surface of the diverter plate 53, and the sliding of the slider 62 can scrape off the impurities attached to the outer wall of the sleeve rod 61.

[0032] By providing an auxiliary stirring device, during the upward movement of the T-shaped top plate 43, the T-shaped top plate 43 pushes the spring rod 71 to move outward, and the spring rod 71 can push the arc plate 72 to slide outward, and the arc plate 72 can drive the semicircular protrusion 73 to move outward together, and the following movement of the semicircular protrusion 73 can produce an intermittent knocking operation with the knocking rod 74, so that the arc plate 72 produces friction vibration, and the arc plate 72 promotes the falling of impurities on its outer wall through the friction vibration between the semicircular protrusion 73 and the knocking rod 74. At the same time, the arc plate 72 drives the through hole 75 to follow the movement, and part of the water flow can flow downward through the through hole 75, so that the water flow pushed upward by the arc plate 72 and the water flow flowing downward through the through hole 75 produce an opposite flow, and water flow friction is generated during the interaction of the water flows to produce a stirring effect, and then the water quality sediment at the bottom of the tube body 1 can be auxiliary stirred through the through hole 75.
