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. 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. The work pressure of up to 64 mpa, supreme office temperature can reach 325 degrees, maximum diameter is 600 mm. From high pressure oil nozzle perfusion of high pressure tight seal oil, formed in the cock ring of high-pressure tightly closed ring, which the body and the plug cone tightly closed surface with a layer of oil film between, to close and lubricating oil, easy opening and closing. Cock valve can into cylindrical or conical valve plug patterns. 5 suitable for high scouring of gas-solid. In the cylindrical plug, square channel normal growth; In the tapered plug, the channel into a ladder type. 。 Specially manufacturing lubricating grease from the top plug body perfusion body between the taper hole and the plug body, forming oil film, to reduce the valve opening and closing torque increase tightly closed and use fixed number of year of survival. For Marine valve detract from the body and plug tightly closed surface friction, common right and use tightly closed valve grease lubricant seat tightly closed structure. 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. 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. Oil lubricating oil hard hard tightly closed tight oil seal cock valve oil plug valves can be divided into the normal oil lubricating cock valve and pressure equilibrium plug valve. 2 body out inlet side Windows default and double groove tightly closed loop structure, plug 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. 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. 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. Such as PVC, ammonium nitrate, the anhydride, caustic soda production devices, or foreign disclosure requirement high medium, such as HF, phosgene, etc. Common hard tightly closed cock, cock the installation form of cone is a dress. Q: tee cock carefully introduce a: tee plug valve is closed or plunger type rotary valve, rotated 90 degrees to make the Industrial Valves plug of tong road intersection of the valve body in the same or separate, to achieve a valve open or closed. 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. So can simplify the dosage of default, loss of valve and pipeline system infrastructure needs a bit of a petition in accessories. The body could be selected according to office medium carbon steel, boron steel and stainless steel materials. 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 can be applied based on temperature and medium of office deems appropriate and use the F4, F46, PVDF, PP, PO, PE, etc from the lubricating 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. The liquid-solid phase medium. The style to make the structure of the cock and lighter, but also had a certain loss. 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. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
