Pneumatic valve adjustment limit expansion joint is introduced

butterfly pneumatic valve limit expansion joint is also known as adjustment limit expansion of form a complete set of pneumatic valve, this product is a new type of pipe connector. Pneumatic valve is a fluid conveying system in the control unit, a cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow, and other functions. Pneumatic valve supporting the expansion pipe in pneumatic butterfly valve used in the main can also is applicable to transport seawater and freshwater, hot and cold water, drinking water, sewage, oil, fuel oil, lubricating oil, refined oil, air, gas, temperature is not higher than the media such as steam and grain powder.
butterfly pneumatic valve supporting expansion at the same time also can bear the axial pressure of pipeline, so that you can at the time of installation and maintenance, according to the site to adjust the size of the installed, at work, not only improve the work efficiency, but also for pipeline equipment such as pumps, pneumatic valve are play a protective role.
butterfly pneumatic valve supporting expansion at the time of installation, at the same time, it should loosen the packing pressure plate bolt, adjust the installation length, and ends with the pipe installed according to design requirements, to check whether the packing is good, the pressure on the packing pressure plate, screw down the bolt by diagonal method do not partial pressure, make it stop leakage.
