What is a boiler soot blowing pressure regulating valve?

    STY boiler pressure regulating valve for STY boiler:

    The STY boiler soot blowing pressure regulating valve is a high-temperature, high-pressure regulating valve specifically designed for soot blowing systems. This valve features a two-stage sleeve structure. The first-stage sleeve primarily regulates the soot blowing pressure, adjusting the pressure and flow rate of the soot blowing gas through the open and closed positions of the valve core. The second-stage sleeve protects the valve core and seat, reducing the erosion and abrasion caused by high-speed fluid on the valve core and seat.

    This valve is specifically designed for the soot blowing system of thermal power generation systems, and its main advantages are:

    1. Reduce erosion and abrasion on the sealing surface, and separate the throttling surface from the sealing surface for a longer service life.

    2. The surfaces of the valve core and valve seat undergo hardening treatment, achieving a hardness of over HRC70, which makes them resistant to erosion and wear, ensuring a long service life.

    3. It allows for a large pressure difference, up to 15MPa, and features a single-seat line seal structure with good sealing performance and no leakage.

    4. The valve core is designed with an anti-erosion groove to prevent high-speed fluid from directly eroding the sealing surface of the valve core
