Why butterfly valve should be equipped with disassembly joint

Butterfly valve limit expansion joint is also known as butterfly valve supporting limit expansion joint, the product is a new type of pipeline connector. Valve is a control part in fluid transportation system, with functions such as cut-off, regulation, inflow, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Butterfly valve with expansion joint used in the valve can also be mainly applied to convey seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam with temperature not higher than 250 degrees and granular powder and other media.
Advantages of butterfly valve installation expansion joint.
Expansion joint mainly improves the positioning bolt, the component in the product can be very good to improve the stability of the equipment.
Butterfly valve-mounted expansion joint can also withstand the axial pressure of the pipeline, so that it can be adjusted according to the size of the installation on site during installation and maintenance.
In the work, it not only improves the efficiency, but also plays a certain role in protecting the pipeline equipment such as pumps and valves. When installing butterfly valve supporting expansion joint, you should loosen the packing platen bolts first, adjust the installation length, install both ends and pipeline according to the design requirements, then check whether the packing is in place, finally press on the packing platen, tighten the bolts diagonally, do not deflect to prevent leakage.
