Valves are increasingly used in a wide range of applications and should be used in different environments. The entire valve in connection with the pipeline or equipment in different forms.It is necessary to pay attention to whether installation or use and maintenance, valve connection is not appropriate, prone to leakage of the valve.
Flanged valve, the most commonly used valve connection. It is convenient to install and disassemble. But they are bulkier and more expensive than threaded valves. It is therefore suitable for pipe connections of all sizes and pressures. However, when the temperature exceeds 350 degrees, as the bolts, gaskets and flanges become relaxed together, the load on the bolts will also be significantly reduced, which may cause leakage to the flange connection under great stress.
