- Q:Stem material
- 5, bearing steelSelection of GCr15, applicable to the nominal pressure is less than 300MPa, the temperature is less than or equal to 300 degrees of ultra-high pressure valve.Used to make the stem more materials, as well as 4Cr10Si2Mo martensitic heat-resistant steel, 4Cr14Ni14W2Mo austenitic heat-resistant steel.The stem nut and the valve stem match with the screw thread, and directly bear the axial force of the valve stem, and the friction between the plate and the support valve. Therefore, the stem nut in addition to a certain strength, but also requires a small friction coefficient, not rust, and stem does not bite and other performance.
- Q:About butterfly valve plate and valve stem connection
- If the bolts were rusted inside, they would not be available unless they were bolted with white steel bolts! Bolt connections will have momentum, and for a long time the bolts may be fatigued and fractured!
- Q:Stem V type PTFE packing maximum pressure /?
- The valve packing VTa is a normal cryogenic valve with a set of V type low leakage graphite packing!Valve stem: the valve stem is not only moving parts, force components, but also seals when the valve is opened and closed.
- Q:Pipeline ball valve in the valve stem generally choose what material?
- Generally, there are the following choices: AISI 4140, A182, F6a, 17-4PH, A182, F316, A182 304, AISI 1040, ENP
- Q:What brand is good for fishing stem?
- Valve brand is not very important, wheels should match better, the length is usually 1.8 meters or 2.1 meters. Valve stem should be noted that poles can not be too soft, in the reservoir, select rod pin slightly hard stem.A raft is a fishing rod on a fishing raft.
- Q:Stem deformation of valve stem
- The main stem has better compression, good thermal insulation, and is not easy to corrosion and rust, it has the sealing function of both sides, more resistant to abrasion and its long service life.
- Q:Can the valve stem be lengthened?
- The extended stem also takes into account the torque and the medium of the valve. Not all valves need to be extended. Generally in the buried ball valve and cryogenic valve needs longer stem.
- Q:How to judge the quality of fishing stem?!
- The regular brand fishing line, mellow, soft texture, good surface smoothness, high strength, good wear resistance nodules. At present, the market of various brands of fishing, whether mixed together.
- Q:What is the connection between the stem and the gate of the low-pressure gate valve?
- The stem is threaded, i.e., the wire inserted on the wire rod and the gate, which is connected to a bolt structure and threads to operate the valve on and off,
