Can pneumatic pinless nylon coated butterfly valve be installed upside down when purchased? 2、 When using pneumatic butterfly valve butt welding, attention shall be paid to:
1. Confirm the geographical location for installing the pneumatic butterfly valve: when there is water or moisture on the ground, change the installation location or completely remove the water or moisture to ensure that the site does not sink. The foundation must be firmly pressed, and then adjust the pipe to a level position with the ground.
2. One end of the pipe shall be fixed to the welding machine first, and then the packing of the pneumatic butterfly valve shall be opened, and one end of the pneumatic butterfly valve shall be fixed. If the fixed length of the butt welding machine is not enough to fix the pneumatic butterfly valve, two fixed machines shall be used to fix it. The other end of the pneumatic butterfly valve shall be adjusted to the same height as the fixed machine. The fixed surface processing heating plate is installed with pressure welding heating to maintain the separation of the joint cooling welding machine.
3. The pipe at the other end shall be welded according to the welding method after being fixed.
、 1、 The electric on-off butterfly valve has the line design of the sealing valve to ensure absolute sealing and no air ingress. The plane design of the valve plate seal can ensure that there is no air leakage and other phenomena, and can completely prevent the valve from being stuck due to long-term non use and non opening, so as to ensure good use.
