Introduction

Double flange force transmission joint is composed of flange loose sleeve expansion joint, short pipe flange, force transmission screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate the pipeline installation error. Double flange force transmission joint is mainly used for loose connection of pump, valve and other accessories. It is suitable for transporting sea water, fresh water, cold and hot water, drinking water, raw sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 ℃. The pipeline can effectively compensate and alleviate the thrust of the pipeline and blind plate, and facilitate the installation, maintenance and replacement of water pumps and valves. In fact, it is the most ideal supporting product in the pipeline installation and operation industry. The metal and sealing ring are selected in strict accordance with the service 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.

1. The equipment is simple and convenient, and the valve equipment can accept the axial tension of the pipeline.

2. The product is made of metal casting or welding, and the loose sleeve part is made of trapezoidal rubber sealing ring under the action of gland and bolt.

3. Use the elastic deformation principle of rubber tightening. Force the sealing ring to deform between the outer wall of the elastic pipe of the joint body for static sealing.

4. The metal and sealing ring shall be selected strictly according to the service performance and user's request. The exterior of the raw material is 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 space between the body and the elastic tube, it has a certain axial and radial displacement.

5. It can effectively compensate and reduce the thrust of pipeline and blind plate in the pipeline, and facilitate the repair and replacement of water pump and valve equipment. It is actually an aspiring supporting product in the operation of pipeline equipment.
