Shengdelong Valve briefly introduces the five points of special attention when installing copper valves:
1. The pipe threaded valve is connected with the pipe thread of the pipe end, wherein the internal thread may be a cylindrical pipe thread or a conical pipe thread, and the external thread must be a conical pipe thread.
2. The internal valve-connected gate valve is connected to the pipe end, and the length of the external thread of the pipe end must be controlled. In order to avoid excessive screwing of the pipe end so as to press the inner end surface of the threaded valve stem, the valve seat is deformed and the sealing property is affected.
3. For valves with threaded connection, when installing and tightening, the hex or octagonal part of the same end of the thread should be wrenched, and the hexagonal or octagonal part of the other end of the valve should not be wrenched to avoid deformation of the valve.
4. The flange of the flange-connected valve and the flange of the pipe end are not only consistent with the specifications, but also require the same nominal pressure.
5. When the valve stem leaks during the installation and commissioning process, tighten the nut at the packing, and pay attention to the force should not be too large, so as not to leak.
