Through opening and closing positions of the valve core, the pressure and flow rate of the blow-off gas are adjusted, and the second-stage sleeve protects the valve core and the valve seat to reduce flushing and erosion of the valve core and the valve seat by the high-speed fluid. STY boiler soot blowing pressure regulating valve, is a kind of high temperature and pressure regulating valve which is specially used for the soot blowing system. The valve is designed as a two-stage sleeve construction. The first sleeve as the main regulator of soot blowing pressure, the valve specifically for the power generation system of the soot blowing system design, the main advantages are: 1. Reduce the erosion of the sealing surface erosion, throttle face and seal surface separation, service life long. 2. Spool, seat surface hardening, hardness up to HRC70, erosion erosion, long service life. 3. To allow large pressure, up to 15MPa, single-seat sealed structure, good sealing performance, no leakage. 4. Spool open anti-scouring groove design, to avoid high-speed fluid directly flush valve plug sealing surface.
