Structural characteristics and application of flat gate valve
Flat gate valve introduction: Flat gate valve for Class150 ~ 900 / PN1.0 ~ 16.0MPa, operating temperature -29 ~ 121 ℃ oil, natural gas, water, oil and other pipelines, used to cut off or connected to the pipeline medium. Flat gate valve applications: flat gate valve for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other pipeline, venting system and steam storage device, used as hoist equipment. Z43 single gate with diversion gate plate valve for natural gas extraction and purification of long-distance pipeline. Structural characteristics of flat gate valve: 1, the seat with O-ring seal and preload force applied to the floating seat structure, so that the two-way flat gate valve import and export seal; and the opening and closing torque of the structure is only ordinary valve 1/2 , Can easily open and close the valve 2, at full open, the channel is smooth to a straight line, the flow resistance coefficient is minimal, no pressure loss, can be used to clean the hair ball line 3, with self-sealing packing structure, without frequent adjustment , Open, close extremely lightweight, and reliable sealing, stuffing box is equipped with an auxiliary seal grease injection structure, the sealing performance is absolutely reliable, truly zero leakage; Solve the general valve packing the most easy to leak the shortcomings 4, flat gate valve closed When the cavity can automatically remove the high pressure to ensure safe use 5, fully enclosed structure, good protective performance, can be adapted to all-weather requirements 6, the seat seal structure should be elastic pre-tightening force, sealing structure at the same time downstream seal . Seat and seal are always face-to-face seals. 7, the seat has a self-cleaning function, and the valve is not open or closed during the direct flow of air erosion. Seat should be made of lubricated, non-abrasive material. 8, the valve actuator failure does not affect the rest of the valve, maintenance and replacement work can be carried out without removing the valve. (1) Yoke Sleeve - The aluminum bronze yoke sleeve is equipped with a needle thrust bearing to minimize operating torque. (2) Stem - thread length up to bracket; pin and spot welding; stable. (3) Pressure Sealed - Simple to assemble, with sectional buckle and silver-plated mild steel washers to help disassemble and achieve the best bonnet seal. (4) Seat Ring - Welded seat ring is perpendicular to the flow path for easy maintenance. (5) Actuators - These valves can be equipped with electric, hydraulic or pneumatic actuators. DN300 following the standard configuration handwheel, DN350 above configuration helical gear operating mechanism. (6) Yoke - The fully assembled yoke passes the seismic test for easy maintenance and installation of the actuator. (7) Gland - Two-piece, self-adjusting gland to avoid being ejected. (8) overall rear seat - hard surface, the longest service life. (9) Flap - The spring-loaded flap regulates itself to reduce actuator torque demand. (10) The overall stop - the overall casting bracket stopper device, positioning the assembly of the bracket valve, making the valve seat more stable and reliable.
