The transmission joint is also known as a compensator or flexible expansion joint. It consists of main parts such as the body, sealing ring, gland, and telescopic short pipe. It is a product used for connecting pumps, valves, and other equipment to pipelines. All parts are connected together through full bolts to form a whole with a certain displacement. This allows for adjustment according to on-site installation dimensions during installation and maintenance. During operation, axial thrust can be transmitted back to the entire pipeline. Not only does it improve work efficiency, but it also provides some protection for equipment such as pumps and valves.
The power transmission joint can be roughly divided into: VSSJAFG (CF) single flange power transmission joint, VSSJAF (C2F) double flange power transmission joint, and VSSJAFC (CC2F) double flanged force transfer dismantling joint
According to structure, it can be roughly divided into: 1. body 2, sealing ring 3, gland 4, short pipe flange 5, stud 6, and nut
Texture of material
Mainly Q235 carbon steel, stainless steel 304L, 316L, cast steel, ductile iron, etc. Choose different materials and models for different purposes.
Size and Pressure
DN40-DN200; Pn10、Pn16、Pn25、Pn40
Applicable medium
This product is suitable for conveying media such as seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam and particulate powder with a temperature not exceeding 250 degrees Celsius
Advantage
1. Simple and convenient installation, convenient valve installation, and able to withstand axial tension of pipelines.
2. The product is composed of metal casting or welding, and the loose sleeve part adopts trapezoidal rubber sealing ring, which is under the action of the gland and bolts.
3. Utilize the elastic deformation principle of rubber compression. Force the sealing ring to deform and perform static sealing between the outer walls of the expansion tube of the joint body.
4. Metal and sealing rings shall be strictly selected according to their performance and user requirements. The material is externally coated with high-strength anti-corrosion paint, and 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 expansion tube, it has a certain axial and radial displacement.
5. It can effectively compensate and alleviate the thrust of pipelines and blind plates in pipelines, and also facilitate the installation, maintenance, and replacement of water pumps and valves. It is actually the most ideal supporting product in the pipeline installation and operation industry.
Product Usage Scope
1. The diamantling joint is a metal manufacturing product with high tensile and compressive strength, superior soft sealing performance, and convenient loading and unloading. It is often used in power and metallurgy.
2. In industries such as water supply and drainage and sewage treatment, it mainly serves as the connection between water pumps, valves, and pipelines.
3. It has a certain multi-directional displacement effect during pipeline operation, which can alleviate the blind plate thrust during pipeline operation and provide certain protection for the pipeline, especially providing great convenience for pipeline installation and maintenance. However, force transfer joints should be used at the outlet of the water pump and at the corners of the pipeline, because the force transfer joints can transmit the blind plate thrust during pump startup to various parts of the pump and pipeline through force transfer bolts, Avoid the concentration of thrust on the near end of the pipeline or pump causing impact damage to the equipment.
