Product Name: metallurgical Valve-F343cx Worm Gear Sector Blind Valve Model NO.: F343CX Trademark: qian-gong-feng Transport Package: Wooden Cases Specification: DN100-1200 Origin: Hebei HS Code: 8481202000 Product Description F343CX worm gear sector blind plate valve, also known as worm gear sector glasses valve, flange valve, sector valve, by the left valve body, middle valve body, right valve body, sector blind plate, screw nut, stainless steel compensator, two worm gear transmission mechanism and so on. It is connected into one body by three screw rods, and fixes three valve bodies on the base separately, forming a rigid structure. The middle valve body and the right valve body are connected by stainless steel expansion pipe, and the left and middle valve bodies are connected by three screw rods with trapezoidal threads at both ends. If the three screw rods are rotated forward (or backward) at the same time, the left and middle valve bodies are compressed (or separated). A blind plate is arranged in the middle of the upper and middle screw of the three screw rods, and the blind plate rotates around the axis. The following two screw rods are equipped with locating blocks of blind plate on the same part. When the blind plate rotates, it can prevent the blind plate from drifting and the seal ring from scratching. One screw rod is equipped with worm wheel drive mechanism to realize the purpose of loosening the clamping valve body.Main performance parameters:Nominal pressure MPa0.250.140.100.05Seal pressure test MPa0.2750.1640.110.054Strength pressure test MPa0.400.2250.150.074Applicative temperature ºCNitrile butadiene rubbersilicon rubberFluororubber<120<200<300Applicative mediumToxic, harmful, flammable gases such as gasUse standardConnection flange size conforms JB/T81-94,Conformity of detection methods GB/T13927-92Major parts materialsBody,gate is carbon steel;Connection shaft,Telescopes are carbon or stainless steel ;The sealing ring is rubberMain Shape Connection Size: Unit: mmDNDD1bn-φdL3004403952212-φ224003504904452212-φ224004005404952216-φ226004505955502416-φ226005006456002416-φ226006007557052420-φ266007008608102624-φ268008009759202624-φ30800900107510202824-φ308001000117511203028-φ308001100127512203028-φ308001200137513203032-φ308001300147514203232-φ308001400157515203236-φ308501500167516203236-φ308501600179017303240-φ308501800199019303244-φ3011002000200021303246-φ301200
