Detailed description of the invention
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of low-tension pulse washing pipe reversely charging device, including staving 1, liquidometer 2, carry hand 3, water filling port 4,
Air relief valve 5, intake valve 6 and outlet valve 7.Wherein, liquidometer 2 is arranged on staving 1 side, the liquid level of reversely charging water in staving 1
Display；Carry hand 3 is arranged on staving 1 both sides, for the carrying of device；Water filling port 4 is at staving 1 top, for installing additional of reversely charging water；
Air relief valve 5 is arranged on staving 1 top, is used for providing reversely charging water required drive；Intake valve 6 is arranged on air relief valve 5 entrance side, is used for
Isolation power gas source；Outlet valve 7 is arranged on staving 1 side, is used for isolating reversely charging water.
In the present embodiment, staving 1 is that rustless steel is cylindrical, is used for containing reversely charging water, and all and staving 1 is joined directly together pipe
The stainless steel part such as line, joint all uses welding, staving 1 pressure-bearing to be not less than 2MPa.
Liquidometer 2 is communication type, is arranged on staving 1 side, and upper and lower side is stainless joint；Liquidometer 2 stage casing is transparent can
Depending on and have scale (minimum scale 0.5L), for the metering of reversely charging water loading amount, liquidometer 2 pressure-bearing is not less than 2MPa.
Carry hand 3 has two, stainless steel, is relatively welded on staving 1 upper side, for the carrying of device.
Water filling port 4 is positioned at staving 1 top, uses the sealing means of screw thread+pad, and pressure-bearing is not less than 2MPa.
The instruction of air relief valve 5 band pressure and degassing function, outlet is connected with staving 1 top by stainless steel tube, for reversely charging
Water provides power；Air relief valve 5 all uses cutting ferrule to be connected with gateway pipeline, dismantled and assembled.
Intake valve 6 is exported and is connected with air relief valve 5 entrance side by stainless steel tube, and connected mode is cutting ferrule, dismantled and assembled, is used for
Isolation power gas source.
Outlet valve 7 entrance is arranged on staving 1 side by stainless steel tube, and connected mode is cutting ferrule, dismantled and assembled, is used for isolating
Reversely charging water.
During installation, first air relief valve 5 is exported the stainless steel tube with staving 1 top and is connected, by the pressure set points knob inverse time
Limit position is transferred to by pin, makes air relief valve 5 be output as 0；Then intake valve 6 is exported and be connected with air relief valve 5 by stainless steel tube, close
Intake valve 6, then intake valve 6 entrance is connected (connecting tube with carrying) with pressing air on the spot；Afterwards by outlet valve 7 entrance and bucket
Water outlet stainless steel tube bottom body 1 is connected, and closes outlet valve 7, installation outlet pipeline (connecting tube with carrying)；Finally it is filled with
Water is poured into staving 1 from water filling port 4, and maximum is less than the full scale of liquidometer 2, screwing hermetic nut.
During work, first confirm to press air for upper on the spot, open intake valve 6, clockwise the rotation of regulation air relief valve 5 setting value
Button to target reversely charging pressure (see remarks), check confirm at liquidometer 2, water filling port 4, air relief valve 5 and outlet valve 7 relevant interface without
Leakage；Slowly small guide vane opens outlet valve 7, until outlet valve 7 outlet line full water, is then shut off outlet valve 7, records liquidometer
The reading of 2；The outlet valve 7 outlet line other end is received and treats, bottom reversely charging pulse tube, the most slowly to open outlet valve 7 and pulse
Isolating valve bottom pipe, observes liquidometer 2 reading afterwards, when about 5L water (by conventional 3/8 inch of pulse tube estimation) reversely charging enters arteries and veins
Washing pipe, then cut out the isolating valve bottom outlet valve 7 and pulse tube, pull down connect bottom pulse tube fill pipeline, this root pulse
Pipe reversely charging water completes；Also have other pulse tube to need reversely charging if neighbouring, be then directly connected to outlet valve 7 outlet line and continue operation i.e.
Can；After pulse tube reversely charging completes, the outlet valve 7 outlet line other end is put in Water Sproading container (such as plastic pail), opens
Outlet valve 7, discharges inner for staving 1 remaining refillable water, closes outlet valve 7 afterwards；Air is pressed in isolation on the spot, closes intake valve 6,
Slowly unscrew air relief valve 5 counterclockwise, the gas in staving 1 is carried out release, until being 0, finally removing intake valve 6 entrance and going out
Water valve 7 outlet line.In filling process, if the water in staving 1 is not enough, require supplementation with, then close outlet valve 7 and intake valve
6, by unscrew the nut of water filling port 4 to staving 1 release after, supplementary water, afterwards tightening nuts, open intake valve 6, to staving
Reversely charging pressure in 1 is set up again.
Remarks: target reversely charging pressure is higher than pulse tube static pressure+technique lateral pressure, and such as, in pulse tube, medium is light water, from
The vertical height of bottom to technique side is 50 meters, then pulse tube static pressure is about 500kPa；Technique lateral pressure is 100kPa simultaneously, then
Target reversely charging pressure need to be more than 500+100=600kPa, such as 700kPa.
Listed above is only a specific embodiment of the present invention.Obviously, the present invention can also have many deformation, ability
All deformation that the those of ordinary skill in territory can directly derive from present disclosure or associate, are all considered as this
The protection domain of invention.
