Plug valve widely used in oil field mining, transportation and refining facilities, but also widely used in the fuel chemical industry, chemical industry, liquefied petroleum gas, natural gas, liquefied gas fuel and hvac industry, and general industry. The body could be selected according to office medium carbon steel, boron steel and stainless steel materials. 1. 5 suitable for high scouring of gas-solid. Plug valve is shut down or plunger type rotary valve, rotated 90 degrees to make the valve plug tong road intersection of the valve body in the same or separate, to achieve a Industrial Valves open or closed. The style to make the structure of the cock and lighter, but also had a certain loss. Q: the utility of the three-way cock valve is what? Answer: English name should be a cock, so the name of righteousness, is of course stem in the direction of the three links, two or a into two into for a into two out, cock is to restrict the export of two. Because cock tightly closed surface movement between wiping with utility, but on the whole paper can absolutely avoid contact with the liquid medium, so it usually can be used in medium with suspended particles. 1. 2. Body out of the inlet side Windows default and double groove tightly closed loop structure, cock in the process of rotation, the tightly closed tightly closed between vice than pressure gradient, until the whole piece of paper or a seated position, initiation enough tightly closed pressure, tightly closed to achieve zero leakage. Cock valve can into cylindrical or conical valve plug patterns. 1. 6 medium can be two-way flow, installation direction without limit, successful online maintenance, use more convenient. 7 unique special preset can avoid static electricity, fire safety, use safety. So can simplify the dosage of default, loss of valve and pipeline system infrastructure needs a bit of a petition in accessories. 。 The liquid-solid phase medium. 1. Four piston at the top of the unique special counter lips tightly closed preset, sees fit and using a soft tight sealing materials and metal diaphragm of diaphragm and debugging gasket assembly can debug tightly closed tightly closed between the surface pressure, make cork flexible rotation, and can guarantee into outlet and flange in the tightly closed on a petition. Another matter special properties of the cock valve when it is convenient for suitable for multi-channel structure, causing a valve can be obtained by two, three, even four different port. In the cylindrical plug, square channel normal growth; In the tapered plug, the channel into a ladder type. Several common cock: soft tightly closed cock soft tight sealing plug valves are often used to corrosion resistance, strong toxicity and high hazard media such as caustic background, strict ban leaks, and valve material will not form pollution situation of media. 1. 1. Can be applied based on the temperature and office media think appropriate and use the F4, Marine valve F46, PVDF, PP, PO, PE and so on since the oil bushing material, good lubricating oil, in the process of the whole office vice friction coefficient is small, tightly closed body flexible operation, use fixed number of year long survival. Such as PVC, ammonium nitrate, the anhydride, caustic soda production devices, or foreign disclosure requirement high medium, such as HF, phosgene, etc. 1. Three pairs of grooved channels tightly closed loop can make solid liner in the body not initiation displacement, and can be reference for actuating bushing initiation of trace variant temperature changes, at the same time between liner and cock initiation strength of friction, a semi-automatic cleaning effect, increased tightly closed the use fixed number of year of survival. Plug valve is the most suitable for as truncation and through media and shunt is suitable for use, but according to the nature of the suit to use and tightly closed surface erosion resistance, sometimes also can be used for throttling. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
