Product Overview J961Y electric power station shut-off valves for nominal pressure PN20.0 ~ 32.0Mpa and P (54) 100V ~ P (57) 170V, the working temperature ≤540 ℃ (where P (57) 170V operating temperature of 570 ℃) of oil a variety of working conditions in chemical, water, fire station and other pipeline, cut off or connected media. Suitable medium: water, oil, steam and so on. Operating modes: manual, gear transmission, electric and so on. Shut-off valve is a common cut-off valve, mainly used to connect or disconnect the line of media, is generally not used to regulate traffic. Suitable pressure shut-off valve, the temperature range is large, but are generally used for the pipeline, small diameter. Station fire station shut-off valve is suitable for a variety of system piping, or turn off the line media. Suitable medium: water, steam and other non-corrosive media. Power station valves and other valves are characterized by high temperature and pressure compared to the unique self-sealing design, the higher the pressure, the more reliable seal. Due to the technical characteristics of the performance, the special conditions of the product but also the formation of other products can not be replaced characteristics. Opening process 1 in the closed position, the mechanical action of the valve body by pressing the valve stem, is pressed against the valve seat. 2 When the handwheel counterclockwise stem the reverse movement, its flat bottom corner to make the ball disengage the seat. 3 stem continues to rise, and the interaction between the valve stem and guide pin spiral groove, so that the ball began to rotate without friction. 4 up to the fully open position, the valve stem to the limit position, the ball rotated to the fully open position. When the shutdown process a closed hand wheel clockwise, the stem and the ball began to fall away from the seat starts to rotate. 2 continues to rotate the handwheel stem being embedded in the spiral groove on its role of guide pins, so the stem and gate while rotating 90 degrees. 3 is about to close when the brake member is in the valve seat without contact rotated 90 degrees. The last four laps hand wheel rotation, angular plane mechanically wedge at the bottom of the stem to the oppression of the ball, making it tightly pressed on the seat, to be completely sealed. The main advantages: 1) compared with the valve, globe valve structure is relatively simple, manufacturing and maintenance are more convenient. 2) sealing surface easy to wear, abrasion, seal better, longer life. 3) When opening and closing the valve stroke is small, open and close a short time, the height of the smaller valve. Main features and uses valves and pipe connections ① welded structure, easy installation, no leaks. ② sealing surface easy to wear, abrasion good sealing performance, long life. ③ compact structure, opening and closing, good height is small, easy maintenance. ④ for water, steam, oil pipelines, high temperature, high pressure characteristics. ⑤ variety of structural forms, user-friendly options.
