Embodiment:
From Fig. 1-4: this device is provided with high-pressure chamber 1, hyperbaric chamber 2, low pressure volumes 12, low-pressure cavity 11, high-pressure chamber 1 and low pressure volumes 12 are provided with pressure gauge 4, the inner of high-pressure chamber 1 is provided with left flange plate 23, filter 3 is embedded on left flange plate 23, Compress Spring 13 is located in filter 3, boundary's dish 18 is provided with between left flange plate 23 and right flange plate 21, the circumferential end surfaces of boundary's dish 18 is provided with 18 oil guiding holes 8, the left side of boundary's dish 18 is provided with lubrication oil cylinder 15, small cylinder 16 is provided with in it, lubricating cavity 7 is provided with between lubrication oil cylinder 15 and small cylinder 16, lubrication oil cylinder 15 is provided with tank filler sleeve, lubricating cavity 7 is communicated with oil guiding hole 8, the right side of boundary's dish 18 is provided with large oil hydraulic cylinder 20, the piston 9 of T-shaped shape is arranged in small cylinder 16 and large oil hydraulic cylinder 20, and with the minor diameter fit both it, y-type seal ring 17 is adopted to seal, the piston 9 of T-shaped shape is also provided with two guide rings 19, on a left side, right flange plate 23, 21 with lubrication oil cylinder 15, small cylinder 16, O type circle 14 is provided with in the end face cooperation of large oil hydraulic cylinder 20, left flange plate 23 is fixedly connected with by 12 connecting bolts 10 with right flange plate 21, be provided with fixed guide bar 22 in the piston 9 of T-shaped shape and its one end be welded on right flange plate 21, the other end is provided with spool 5, the circumferential surface of spool 5 is provided with multiple pod apertures 6, spool 5 is separable with fixed guide bar 22, the piston 9 of T-shaped shape can be left along the external diameter of spool 5, move right, right flange plate 21 is provided with multiple spilled water hole differed in size.
Use the utility model, the high-pressure water pressure of this device can reach 10Mpa, and its Pressure reducing ratio is determined by the ratio of the different net sectional area of piston 9 arranged on left and right sides.High pressure water enters hyperbaric chamber 2, its hydraulic pressure acts on piston 9, promote it to move right, spool 5 is separated with piston 9, high pressure water enters low-pressure cavity 11 by the pod apertures 6 on spool 5, and along with the low pressure line water yield is constantly supplemented, its pressure rises gradually from nothing, according to the opening degree with water consumption auto-controlling piston 9 and spool 5, now the side of low-pressure cavity 11 maintains certain pressure simultaneously.Its masterpiece is used on the effective cross section of the piston 9 of low-pressure cavity 11 side, promotes piston 9 and is moved to the left, and along with water consumption interest is in stable, the position of piston 9 is also relatively fixing, and the hydraulic pressure of piston 9 arranged on left and right sides also reaches balance.Because the stressed net sectional area of piston 9 high and low pressure arranged on left and right sides is different, therefore the pressure obtained is different, also just serves the effect of decompression.The utility model is mainly applicable to deep well in mine decompression water system.
