进口蝶形阀哪家品牌好

进口蝶形阀Product Description:

The utility model comprises a body, a sealing ring arranged on the peripheral surface of the body and a movable part rotatably arranged in the body. The body is a shell with a cylindrical fluid path. The sealing ring is pasted on the inner peripheral surface of the body, which is a soft elastic ring. The peripheral surfaces of the front and rear ends of the sealing ring form an inward protruding annular protrusion, and the body forms an annular groove corresponding to the protrusion position of the sealing ring, The protruding strip is embedded in the groove to realize the fixation of the two. The movable part is arranged on a rotating shaft, which passes through the body to the outside and is connected with a reciprocating cylinder. Due to the setting of the sealing ring, the sealing performance of the butterfly valve can be improved, and the sealing ring and the body can be embedded in the protruding strip through the groove to improve its stability.

进口蝶形阀characteristic:

Butterfly valve, also known as flap valve, is a regulating valve with simple structure. At the same time, it can also be used for on-off control of medium in low-pressure pipeline. Butterfly valve is applicable to pipelines conveying various corrosive and non corrosive fluid media in engineering systems such as generator, gas, natural gas, liquefied petroleum gas, urban gas, hot and cold air, chemical smelting, power generation and environmental protection. It is used to regulate and cut off the flow of media. The valve plate of the existing butterfly valve is usually a complete circular plate shape, which rotates around its own axis in the valve body and is tightly sealed between the valve plate and the inner wall of the valve body. Its sealing performance is poor and easy to leak.

进口蝶形阀Principle:

The groove is not opened to the position corresponding to the outer periphery of the body on the rotating shaft, that is, the position corresponding to the outer periphery of the body on the rotating shaft forms an outward convex arc section, so that the wall strength corresponding to the position of the body on the outer side of the rotating shaft is stronger than other positions on the same layer, so that it still has high strength and will not be damaged when receiving the force in the direction of fluid flow. Due to the setting of the sealing ring, the sealing performance of the butterfly valve can be improved, and the sealing ring and the body can be embedded in the protruding strip through the groove to improve its stability. In specific implementation, the surface of the movable part can also be provided with a number of reinforcing ribs, which can be horizontal reinforcing ribs along the fluid direction to enhance the strength of the movable part. Please refer to the figure at the same time. The outer surface of the body is also provided with two ring grooves arranged at intervals. The ring groove is connected with the pipeline with clamps to realize rapid and reliable connection in the pipeline, improve the construction efficiency and reduce the installation and maintenance costs.
