SSJB-3 Dresser type mechanical flexible coupling with tie rods
Dresser type flexible coupling is also called style38 coupling, mechanical coupling, dresser coupling, it is made by welding or casting of iron or steel. There are rubber gaskets at both ends of follower and middle ring. Under the action of the gland and the bolt, the compression elastic deformation principle of the rubber is used to force the sealing ring to deform on the outer wall of the telescopic tube of the joint body of the joint body. The static sealing is carried out. The metal and sealing ring are selected according to the performance and user requirements. The material is coated with high-strength anti-corrosive paint. The connecting bolts of each part are made of high-strength carbon steel or stainless steel because there is a certain gap between the body and the telescopic tube. It has a certain axial and radial displacement, can effectively compensate and relieve the blind thrust of the pipeline in the pipeline, and can facilitate the installation, maintenance and replacement of the pump and the valve, and is a good accessory product for pipeline installation and operation.
Because this series of coupling are metal products, it has high tensile and compressive strength, superior soft sealing performance, convenient loading and unloading, etc. It is widely used in electric power, metallurgy, water supply and drainage and sewage treatment industries, mainly for water pumps. With the connection between the valve and the pipeline, it has a certain multi-directional displacement function in the pipeline operation, which can alleviate the blind plate thrust in the pipeline operation and provide certain protection to the pipeline, especially for the installation and maintenance of the pipeline. Great convenience, however, dismantling joint should be used at the pump outlet and the pipe corner, because dismantling joint can transmit the blind thrust of the pump to all parts of the pump and pipeline through the force transferring bolts, so as to avoid the thrust concentrated on the proximal end of the pipe or pump, impact damage equipment occurs.
