Pressure equilibrium plug valve is divided have common oil lubricating cock valve's unique place outside, still have the following lists the unique place:  A. The installation of pressure balanced plug valve plug cone form for inversion. 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.  the valve is closed, because they were on the plug cone plane or the size of the object surface is poor, perfusion of tightly closed high-pressure oil increases power plug body suffered aspirant, make the plug body and the valve tightly closed surface can better tightly closed. To detract from the body and plug tightly closed surface friction, common right and use tightly closed valve grease lubricant seat tightly closed structure. B。 In open valve flap, the pressure of the valve body inferior vena and pipeline medium pressure equalization, tightly closed high-pressure oil cavity on the plug body suffer downward thrust, and make the plug cone and the body tightly closed surface, revealed slight gap between rotating torque will work when the plug body impairment. From the high pressure oil nozzle Marine valve into the high-pressure injection tightly closed 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.  2 plug valve, pressure equilibrium  to detract from common hard tight sealing plug valve torque, often see fit to use pressure equilibrium plug valve. B。 To further writedowns cock valve opening and closing force, it is generally believed and use of cock of the diameter of the right way, so the cock generally considered appropriate and using rectangular flow channel, this approach in derogation cock valve opening and closing torque at the same time, increasing the fluid resistance of the cock  C. Plug cone tightly closed place STL surfacing alloy material or deem appropriate and hardening technology using appearance, strengthen the tightly closed surface abrasion resistant and corrosion resistant experienced, use fixed number of year long  D of survival. Plug cone looks fine grinding to the mirror, and the body tightly closed grinding, have lower open-close torque. The work pressure of up to 64 mpa, supreme office temperature can reach 325 degrees, maximum diameter is 600 mm. Also can try our best to take care of tightly closed. C。 Under the condition of high temperature, the heating of cock expansion can be for reference through the up and down, to prevent the vice wedge die tightly closed.  1, normal oil lubricating oil plug valves  A. Common hard tightly closed cock, cock the installation form of cone is a dress. 。 Because the selected tightly sealed lubricating oil according to actual working condition. Q: editrice oil lubricating oil hard tightly closed cock a: hard tightly closed oil lubricating oil plug valves can be divided into the normal oil lubricating cock valve and pressure equilibrium plug valve. Hard tightly closed cock  oil lubricating oil, is considered appropriate and using oil lubricating oil can detract from the opening and closing right moment, but likely to medium pollution. The upper portion of the plug cone have a check. 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.
