Flip oil seal plug

532 flip oil seal plug Name: flip the oil seal plug aka: Flip-oil lubricated plug valves, pressure balanced plug valves flip Model: X47W / F, X347W / F uses - flip oil seal plug can be divided into conventional oil-lubricated plug valves and pressure balanced plug valves. Special grease injected from the top of the plug body between the body taper and plug body, forming a film to reduce the valve opening and closing moments, improve sealing and service life. The products are widely used for a variety of working conditions in petroleum, chemical, pharmaceutical, fertilizer, power industry and other pipeline, cut off or connected piping media structure principle - flip oil seal plug from the high pressure oil injection nozzle high pressure seal oil, high pressure seal around the cock ring, that is a layer of film between the body and the cocks cone sealing surface, but both closed lubrication, open and close easily. ● flip oil seal plug seal 1. Conventional hard cock, cock cone installation is being installed. In order to reduce friction and cock valve sealing surface, the valve seal structure generally use grease seal seat. From the high-pressure oil injection nozzle high pressure seal oil, high pressure seal around the cock ring, that is a layer of film between the body and the cocks cone sealing surface, but both closed lubrication, open and close easily. 2. In order to further reduce the lifting power plug repellent, usually a method to reduce the diameter of the cock, cock it usually rectangular channel, this method of opening and closing torque while reducing the plug, plug the fluid resistance increases 3. cocks cone seal area STL surfacing alloy material or to use surface hardening techniques to enhance the sealing surface of the wear-resistant and corrosion resistance, long service life 4. cocks surface grinding to a mirror cone, and the valve seal surface grinding, has a lower opening and closing torque. ● Pressure balanced plug - in order to reduce the torque of conventional hard sealing plug, often with pressure balanced plug valves. Pressure balanced plug valves in addition to a conventional oil-lubricated plug valves features, there are the following characteristics: 1. Installation pressure balanced plug cock cone is flip. An upper cone there is a check valve cock. When the valve is closed, due to the difference in cross-sectional area from top to bottom cone cock, so that the injected high pressure seal oil plug body by upward lifting force, so that the sealing surface of the valve plug body and better seal. 2. Open the valve moment, medium pressure valve under pressure balance chamber pipe, high pressure seal oil on the chamber so that the plug body being thrust down, leaving room cock cone and valve sealing surface appear small gap, torque when rotating the plug body will effectively be reduced. Sealing can also protect. 3. In the high-temperature condition, the thermal expansion of the plug can be absorbed by their movements, avoid Sealing wedge death. Oil lubrication hard seal plug, although the use of oil lubrication can be appropriately reduced closing torque design specifications - Design Standard: API 6D, API599 Structure length: ASME B16.10 connection standard: ASME B16.5 Pressure test: API 598 product identification: MSS SP-25 supply specifications: API 599 Parameters - Size: 1/2 "--14" Temperature: -40 ~ + 200 ℃ Pressure: 150LB-900LB material: carbon steel, stainless steel, alloy steel, cold steel, etc.
