Profile 1. The high-purpose inlet valve is installed at the inlet of the high-pressure heater of the boiler feed water system, and the high-purpose outlet valve is installed at the outlet of the loaded high-pressure heater, forming a high-purpose bypass system with the high-pressure heater. When the high pressure heater fails, the inlet valve will close quickly within 2 seconds, the bypass pipe of the high pressure system will be opened, and the outlet valve will close quickly. Boiler water is fed into the boiler through a bypass pipe. Ensure system safety and boiler normal feed water. 2. Structural features the valve is angular structure, the entrance valve structure is a double-seat globe valve, the disc by the force of the medium to open, failure, the disc in the role of the hydraulic cylinder, rapid downward movement, close the main channel. Open the bypass at the same time. Exit valve until the return valve form, the rotation of the hand wheel can control the opening height of the disc. Normally, it is in the open state; in case of accident, it is in the closed state. Valve cover with pressure - tight sealing structure, safe and reliable. Seat and disc sealing surface material using plasma jet welding cobalt base cemented carbide. High hardness, abrasion resistance, erosion resistance, long service life.
