Said pressure meter also can be located on the pipeline between said supercharging one way valve P2 mouth and the said interface D or be located on said interface D and the said pipeline of suppressing between the equipment.
The utility model utilizes and lifts the pressure reduction principle of end cylinder and the rectified action of two one way valves through to the rationally reliable control of two-position four-way valve, realizes giving the equipment of suppressing to pressurize; With the 31.5Mpa emulsion power pack is example explanation the utility model course of work:
(1) two-position four-way valve is got to " normal pressure " shown in Figure 1 position, open the feed liquor stop valve, close and unload pressure cutoff valve, the 31.5Mpa emulsion is divided into two-way through the normal pressure one way valve, and a road direction is lifted the epicoele fluid injection of end cylinder, the lower end that piston rod is moved to lift end cylinder; To suppressing equipment, feed flow reaches balance and stops feed liquor when the equipment pressure of suppressing is 31.5Mpa through supercharging one way valve for another road;
(2) after feed flow reaches balance; Two-position four-way valve is got to " supercharging " position shown in Figure 2, and the 31.5Mpa emulsion extrudes the emulsion that moves and will lift end cylinder epicoele on the piston rod to the cavity of resorption fluid injection of lifting end cylinder; Because the emulsion pressure of extruding is higher than 31.5Mpa; Make normal pressure one way valve reverse anchor, the supercharging one-way valve opens, emulsion is extruded to the equipment of suppressing; When the equipment pressure of suppressing reaches desired pressure values (pressure values reads from pressure meter), get to two-position four-way valve " normal pressure " position again and carry out pressurize;
(3) if when the equipment pressure of suppressing does not reach desired pressure values; Get to two-position four-way valve " normal pressure " position and carry out fluid infusion; After lifting end cylinder and withdrawing fully, get to two-position four-way valve " supercharging " position again; So back and forth, when the equipment of suppressing reaches desired pressure values, get to two-position four-way valve " normal pressure " position again and carry out pressurize;
(4) suppress finish after, close the feed liquor stop valve earlier, open again and unload pressure cutoff valve, treat to remove the equipment of suppressing again after the release.
The advantage of the utility model is, realizes suppressing the equipment pressurization through the emulsion of recycle emulsion power pack, and is safe and reliable, simple to operate, easy to use, reduces cost efficient energy-saving.
