Pressure balanced flip cock

533 pressure balanced plug flip Name: Pressure balanced plug flip aka: Pressure balanced oil seal plug flip, flip pressure balanced plug Type: X47W / F, X347W / F uses - pressure between the body and the sealing surface has a balanced flip cock tank, may at any time through the nozzle to inject grease seal seat, increasing the sealing performance, and reduction of conventional hard seal plug torque. This product is suitable for pipeline petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions, or turn off the line media. Structural principle - 1. Pressure balanced plug cock cone installation 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 Key Features - reasonable structure, reliable sealing, excellent performance, attractive appearance; switching lightweight, small resistance; between the body and the sealing surface has a tank, may at any time through the nozzle to inject grease seating, increased sealing performance; design specifications - Design Standard: API 6D, API599 Structure length: ASME B16.10 connection standard: ASME B16.5 Pressure test: API 598 product ID: MSS SP -25 delivery specifications: API 599 Parameters - Size: 1/2 "--14" Temperature: -40 ~ + 200 ℃ Pressure: 150LB-900LB material: carbon steel, stainless steel, alloy steel, cold steel, etc.
