The main function of the power transmission joint is to transmit radial torque, which can connect the valve and the pipe as a whole. The installation length itself can be adjusted through the anchor bolts. The most common one is the double flange power transmission joint. The model specifications are VSSJAF (C2F), single flange power transmission joint VSSJAFG (CF), and detachable double flange power transmission joint VSSJAFC (CC2F).
Extended information:
Henan Yongan valve manufacturer (expansion joint, filter, compensator, waterproof casing, etc.) is a company integrating research, development, production, sales and services. Enterprises that produce pipeline equipment.
Note:
The main function of the expansion joint is to expand and contract in the pipeline, compensate for the deflection caused by thermal expansion and contraction of the pipeline, and facilitate the installation and disassembly of gate valves and centrifugal water pumps. , inspection and repair. Commonly used are double flange loose sleeve limit switch expansion joint VSSJA-2 (B2F) and expansion joint SSQ. There are also single flange limit switch expansion joint VSSJA-1 (BF), flange type loose sleeve expansion joint VSSJA screw cap type loose sleeve expansion joint SSJB etc.
The functions of the expansion joint and the power transmission joint are basically the same, but the connectors and the application environment are still slightly different. The expansion joint can be radially telescopic within a certain range, or it can be radially telescopic within a certain range. It can get rid of the deviation caused by the different radial directions of the pipeline connection within the angle of view, which can greatly facilitate the installation and disassembly of the gate valve pipeline. It can be arbitrarily telescopic within the allowable telescopic amount of the pipeline. Once the telescopic amount is exceeded, the telescopic amount is limited. The position switch can ensure the normal operation of the pipeline. The expansion joint is connected by screws. The expansion joint generally has a double flange connection, with one side being flanged and the other side being welded.
Expansion joints and power transmission joints are suitable for chemical plants, crude oil, electric power engineering, pharmaceutical industry, aerospace, fire protection, metallurgical industry, military, shipbuilding industry, natural gas, nuclear power plants, urban construction, plumbing installation and ecology Environmental protection and other manufacturing industry infrastructure construction and maintenance needs.
