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. Flat gate valve features: 1, the seat with O-ring seal and preload force applied to the floating valve seat structure, so that the two-way seal plate gate valve import and export; and the structure of the opening and closing torque is only ordinary valve 1/2, to achieve a relaxed open, Close the valve 2, at full open, the channel is smooth as a straight line, the flow resistance coefficient is minimal, no pressure loss, can pass the ball cleaning line 3, using self-sealing packing structure, without frequent adjustment, open, close extremely lightweight, and reliable sealing, stuffing box is equipped with auxiliary seal grease injection structure, the sealing performance is absolutely reliable, truly zero leakage; solve the common Valve packing at the most easy to leak the ills 4, when the flat gate valve closed automatically remove the high pressure chamber to ensure the safety of use 5, fully enclosed structure, protective performance, can adapt to all-weather requirements Z43F flat gate valve structure Flat gate valve structure: 1. Sealing structure of the valve seat should be elastic pre-tightening force, sealing structure at the same time downstream sealing seat. Seat and seal are always face-to-face seals. 2. Seat has a self-cleaning function, and the valve is opened or closed during the direct flow of air erosion. Seat should be made of lubricated, non-abrasive material. 3. 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 - 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. Standard Specification: Design and manufacture of standards: JB / T 5298 Structure length standard: JB / T 5298 Connection flange standard: GB / T 9113 Pressure temperature grade: GB / T Test test standards: GB / T, JB / T 5298 Parts materials and conditions: Nitric acids Alectinib Intermediates,Intermediates Of Alectinib,Alectinib Intermediates Cas 1256584-73-2,Cdmo For Alectinib Intermediates Jinan Guoding Pharmaceutical Co.,Ltd , https://www.jnguodingpharma.com
