Yongjia Zhenghong Valve Factory specializes in the production of high temperature and high pressure power station gate valve branch pipe at both ends of the welded structure, welding according to the groove can be made according to standards or user requirements. The high temperature and high pressure power station shut-off valve is used in high temperature and high pressure water, steam, oil, and superheated steam pipes of thermal power plants, petrochemicals, metallurgy, etc.
Structural features of high temperature and high pressure power station valves: high temperature and high pressure power station has no valve cover in the middle of the valve, pressure self-tightening, connecting gate is wedge type, elastic gate or wedge double gate structure, gate / valve seat double side Surfacing weld-based hard alloy, high temperature creep resistant design, valve stem adopts nitriding type precipitation hardening stainless steel, manual, gear (bevel gear and spur gear) transmission, electric drive and other driving methods.
There are two standard forms of high temperature and high pressure power station valves, one is the imported type that follows the ANSIB16.34 and JISL101 standards, and the other is the national standard type according to the JB3595 standard, which follows the temperature-pressure rating is consistent, in some pipelines. There is some sort of exchange relationship.
The middle part of the high temperature and high pressure power station is self-tightening with no valve cover pressure, and has good sealing performance under high temperature and high pressure conditions. The power station valve seal has two materials, one is low carbon steel and the other is flexible graphite 316 wire (net). The surface of the sealing surface is welded with a hard alloy. The pure metal layer after processing is ≥3mm. It has the characteristics of wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.
