Introduction to Single Flange Loose Sleeve Power Transmission Joint

VSSJAFG type single flange loose sleeve power transmission joint is a new product for connecting pumps, valves, pipelines, and other equipment to pipelines. It is connected by full bolts to make it a whole, with a certain amount of displacement, facilitating installation. The single flange loose sleeve power transmission joint produced by the innovative pipeline can withstand the axial pressure of the pipeline. In this way, during installation and maintenance, adjustments can be made according to the on-site installation dimensions, which not only improves work efficiency, but also plays a certain protection role for pipeline equipment such as pumps and valves.

Use of single flange loose sleeve power transmission joint

VSSJAFG single flange loose sleeve power transmission joint is suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and particulate powder with a temperature not higher than 250 degrees Celsius.

Advantages of single flange loose sleeve power transmission joint

1.VSSJAFG type single flange loose sleeve power transmission joint is simple and convenient to install, convenient for valve installation, and can withstand the axial tension of the pipeline.

2.VSSJAFG type single flange loose sleeve power transmission joint is composed of metal casting or welding, and the loose sleeve part adopts trapezoidal rubber sealing ring under the action of gland and bolts.

3.The VSSJAFG type single flange loose sleeve force transmission joint utilizes the elastic deformation principle of rubber compression. Force the sealing ring to deform between the outer walls of the expansion tube of the joint body for static sealing.

4.The metal and sealing ring shall be selected strictly according to the use performance and user requirements. The VSSJAFG single flange loose sleeve power transmission joint material is coated with high-strength anti-corrosion paint on the outside, 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 facilitate the installation, maintenance, and replacement of water pumps and valves. It is actually an ideal supporting product in the pipeline installation and operation industry.

VSSJAFG type single flange loose sleeve power transmission joint is suitable for connecting one side to the flange and welding one side to the pipeline. During installation, adjust the installation length between both ends of the product and the pipe or flange. After installation and welding, tighten the gland bolts diagonally and uniformly to make them a whole with a certain amount of displacement, which is convenient for installation and maintenance, and can be adjusted according to the on-site dimensions. During operation, the axial thrust can be transmitted to the entire pipeline.
