Description
Technical field
The utility model relates to high-pressure hydraulic pump technical fields, more particularly, to a kind of oil of bellows high-voltage energy-storage damper
Valve.
Background technique
Rolling de-scaling pumping plant of plate has more three plunger high-pressure water pumps, in order to reduce the pressure pulsation of three plunger high-pressure water pumps
Vibration to impact and the generation of pump ontology and high pressure pipe network, so the outlet pumped at every is assembled with a bellows high pressure and stores
Energy damper, but it is going into operation soon, bellows high-voltage energy-storage damper does not work, and shell is ice-cold, nitrogen pressure is detected with table,
Entrance side is up to 240bar, and outlet side is up to 390bar, fills pressure, and the de-scaling of entrance side and outlet side considerably beyond nitrogen
Highest work pressure is 220bar and 360bar.It is originally the pressure and the curve of time of three plunger high-pressure water pumps output high pressure water flow
It is wave curve, outlet side wave crest is 380bar, and some wave crests are even up to 390bar, if three plunger high-pressure water pump at this time
Off-load, the pressure of the entrance of bellows high-voltage energy-storage damper oil valve are reduced to 3bar or so by 390bar moment, and oil valve top
Pressure is 390bar, generates very big pressure drop, and oil valve spool moment is closed.Due to the sealing effect of oil valve spool and valve seat
It is good, so that the intracorporal pressure of oil valve spool upper case is maintained at 390bar.When the unloading valve of three plunger high-pressure water pumps is closed, high pressure
Water pressure is not enough to overcome oil valve upper pressure, and oil valve cannot be opened, and the leather bag for filling nitrogen cannot generate contraction and expansion,
High-voltage energy-storage damper stops working, and shaped like ornaments, loses the effect for reducing high pressure water flow pulsation.
When all bellows high-voltage energy-storage dampers do not work, the superposition that entire high pressure pipe network is subjected to impact is generated
Violent vibration is breakneck, while three plunger high-pressure water pumps are also easily damaged, and are shortened the working life.

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As shown in Figures 1 to 7, the oil valve of the bellows high-voltage energy-storage damper, including valve seat 1 and the spool being located on valve seat
2, the conical surface that spool is corresponded on valve seat is equipped with the valve base sealing conical surface 3, and the valve base sealing conical surface 3 is equipped with the gas pressure relief slot 4 for pressure release.
Be closed in the intracorporal high pressure water of shell can the pressure release from the two gas pressure relief slots, so that high pressure water flow is opened easily
Oil valve enters high pressure accumulator shell, and high pressure accumulator is enable to continue to work normally, and plays and absorbs high pressure water pulsation and reduce
High pressure pipe network, equipment vibration effect, keep accumulation of energy damper stable and reliable in work；And structure is simple, at low cost.
Gas pressure relief slot 4 is arranged radially along the valve base sealing conical surface, and isolated area 5 is annular groove, and annular groove is along sealing surface circumferential direction
Setting.Gas pressure relief slot top slot is corresponded on the valve base sealing conical surface 3 equipped with isolated area, and leather bag is avoided to damage.
Gas pressure relief slot 4 and isolated area 5 are arc groove.Gas pressure relief slot is to be located on the valve base sealing conical surface symmetrical two；Valve seat
Pressure release groove depth on sealing cone is in 0.4-0.6mm.
Isolated area setting at the top of the valve base sealing conical surface, valve base sealing conical surface top is fillet, can be formed and be protected to leather bag.
Preferred embodiment are as follows:
Symmetrical gas pressure relief slot and an isolated area there are two setting on the valve base sealing conical surface, are closed in the intracorporal high pressure water of shell
Can the pressure release from the two gas pressure relief slots, so that high pressure water flow is opened oil valve easily and enter high pressure accumulator shell, make high pressure
Accumulator can continue to work normally, and play the role of absorbing high pressure water pulsation and reduce the vibration of high pressure pipe network, equipment.And
Isolated area can make the leather bag for the high pure nitrogen for filling 160bar avoid contacting with the notch of cular arc groove, and leather bag is avoided to damage.
Gas pressure relief slot is that two R2.5mms parallel with sealing cone, depth 0.5mm wide are symmetrically processed on sealing cone
The cular arc groove of 3mm is spent, moment makes the intracorporal high pressure water flow of high pressure accumulator shell by two cular arc groove pressure releases, works as high-pressure column
High pressure water flow easily opens oil valve spool when plug pump is suppressed again, into high pressure accumulator shell, keeps preliminary filling 160bar high-purity
The leather bag of nitrogen compresses and diastole.
Annular isolation area be on the sealing cone of oil valve valve seat, be parallel to sealing cone process a layer thickness be 0.5mm,
Length is since R6 circular arc and sealing surface intersection point to center position 5mm, when oil valve spool is closed, the natural shape between spool
At height 0.5mm annular region, make fill 160bar high pure nitrogen leather bag avoid with the notch of cular arc groove contact, keep away
Exempt from leather bag damage.
Pressure release effect is very good, and high pressure accumulator is at work, high when first hydraulic pressure wave crest is after high pressure accumulator
Press the high pressure water in accumulator shell moment can pass through gas pressure relief slot pressure release, after second hydraulic pressure wave crest enters oil valve, due to
The effect of pressure difference, high pressure water flow can open oil valve spool easily, enable high pressure accumulator continue normal work, oil valve with
The frequency that frequency is 948/ point opens and closes, and the leather bag of preliminary filling high pure nitrogen is shunk and diastole according to this frequency in shell,
High pressure water flow pulsation is absorbed, not only the water pressure fluctuations of stable high voltage water de-scaling, improve de-scaling quality reduces high pressure pipe network, sets simultaneously
Standby vibration extends the service life of equipment.
High pressure accumulator shock absorber application is in high pressure plunger water pump before, and when the moment of high-pressure hydraulic pump off-load, high pressure stores
Energy shock absorber fluid valve core top and lower part generate great pressure difference, cause spool to be closed rapidly, make the intracorporal high pressure water quilt of shell
It is stranded in the housing.
It is provided by the utility model be symmetrically processed on the oil valve valve base sealing conical surface two it is parallel with sealing cone
Cular arc groove, moment makes the intracorporal high pressure water flow of high pressure accumulator shell by two cular arc groove pressure releases, when high-pressure plunger pump again
Secondary high pressure water flow when suppressing easily opens oil valve spool, into high pressure accumulator shell, makes preliminary filling 160bar high pure nitrogen
Leather bag compression and diastole.When oil valve spool is closed, the height 0.5mm annular region of self-assembling formation between spool, with a thickness of
4mm high pressure accumulator leather bag avoids the leather bag for the high pure nitrogen for filling 160bar into not this gap 0.5mm
It is contacted with the notch of cular arc groove, avoids leather bag from damaging, extend the service life of leather bag.
It above are only and above-mentioned technical characteristic can form multiple in any combination to be illustrated to the utility model preferred embodiment
The embodiments of the present invention scheme.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
