1、Purpose

Mainly installed on water and steam pipelines as opening and closing devices (such as steam turbines, boiler drainage valves, regular boiler discharge valves, and main desuperheating water valves), most of the drainage water systems in thermal power plants currently use domestic ordinary valves or imported valves. Due to the structural reasons of these valves, the valve core and valve seat are subject to long-term erosion and wear of high-temperature and high-pressure fluids, resulting in lax valve closure, This causes internal leakage of the drainage system valve. In view of this, our company has developed a specialized valve that can solve the problem of internal leakage - an anti erosion stop valve.

Structure description:

1. When high-pressure medium enters the valve, it first depressurizes the valve cage to release pressure energy and noise, so that the fluid does not erode the sealing surface of the valve core and valve seat, thereby avoiding erosion. By moving the valve disc up and down, the flow rate of the valve can be adjusted arbitrarily, with adjustability.
2. High temperature, high pressure, and erosion resistance. The main components are made of high-quality stainless steel, and the sealing parts of the valve core and valve seat are welded with special processing technology of Stellite hard alloy. The welding layer on the sealing surface is not less than 2.5mm.
3. The contact between the valve disc and the valve cage does not generate friction, and the valve cage is positioned vertically, making the valve close tightly without leakage and open flexibly without jamming.
4. The valve stem and valve disc adopt a flexible structure, which can adjust problems such as scratches and leaks caused by non concentric valve stems during the manufacturing process.
5. The surface of the valve stem is treated with corrosion-resistant nitriding, which has good rigidity, wear resistance, and scratch resistance.
6. The filler is flexible graphite with nickel wire added inside, which is soft and wear-resistant and will not scratch the valve stem.
