The "high-pressure VFR cam deflection valve" developed by Chuanyi is a new development for high-parameter conditions such as coal conversion and petroleum refining, such as pulverized coal transportation and coarse gas shut-off adjustment of coal chemical vaporization furnace. Products, mainly including nominal pressure ANSI600 ~ ANSI900, nominal diameter DN50 ~ DN400. The valve adopts eccentric structure design, small wear and small operating torque; the ball core and the valve stem are splined, the adjustment precision is high, and the pressure difference is large; the double-channel sealing valve seat and the anti-loose retaining ring structure have low valve leakage rate. It is convenient to install, repair and disassemble; the tungsten carbide in the valve body cavity is welded, the surface of the valve inner part is welded or the whole cemented carbide such as tungsten carbide has high hardness and strong flushing resistance.
At present, in the fields of coal conversion, petroleum refining equipment, and other high-parameter valves, foreign products are used. The successful development of the “High Pressure VFR Cam Deflection Valve†of Sichuan Instrument will not only increase the specifications of the Sichuan Instrument Control Valve, but also enhance the supporting capacity. At the same time, it will greatly enhance the competitiveness of the industry with high parameters and severe conditions, and break the foreign monopoly. . It is expected that the annual demand for this series of valve products will reach about 1 billion yuan, and the market prospect is more optimistic.
