The gas-liquid holding vessel is the gas-liquid holding vessel with pre-compressed air cleaner.
The connection end of the First piston bar and second piston bar is the concave-convex curved surface being mutually matched, and two connections End pressure transmission is realized by point contact.
Due to adopting said structure, hydraulic cylinder of the present utility model and pneumatic cylinder to fit together by connecting seat so that One sealing space in interval between hydraulic cylinder and pneumatic cylinder, and the second piston in the First piston bar and pneumatic cylinder in hydraulic cylinder Bar is contacted in this sealing space, and so as to prevent altering oil, gas blowby, further, this utility model is additionally provided with gas-liquid storage Tank, is connected the second breathing air cavity of the gentle cylinder pressure of the first breathing air cavity of hydraulic cylinder with gas-liquid holding vessel by pipeline, so as to The oil-gas-liquid of leakage is entered into gas-liquid holding vessel, the phenomenon for altering oil, gas blowby is fundamentally prevented.
In sum:Piston accumulator involved by this utility model patent, anufacturability is strengthened, manufacture difficulty Reduce, reliable operation can extend the life-span of piston accumulator, can fundamentally solve piston accumulator and alter oil, gas blowby Phenomenon.
Description of the drawings
Fig. 1 is piston accumulator structural representation.
Specific embodiment
Below with reference to accompanying drawing and it is embodied as case this utility model is described in further detail.
As shown in figure 1, piston accumulator is fitted together plus upper band precompressed by hydraulic cylinder and pneumatic cylinder by connecting seat The gas-liquid holding vessel 9 of formula air filter is constituted;Described hydraulic cylinder by hydraulic cylinder 1, first piston 3, First piston bar 5 and First guiding end cap 7 is constituted;Described pneumatic cylinder is oriented to end cap by air pressure cylinder body 2, second piston 4, second piston bar 6 and second 8 compositions.When the First piston bar 5 in hydraulic cylinder is stretched out, pressure actuation is carried out by a contact, promote second in pneumatic cylinder Gas in the compressed gas cylinder pressure air cavity of piston rod 6;When the second piston bar 6 in pneumatic cylinder stretches out, pressed by a contact Power is driven, and promotes the liquid in the First piston bar compression hydraulic cylinder sap cavity in hydraulic cylinder.
It is for correcting First piston bar 5 and second piston bar 6 that the first described guiding end cap 7 and second is oriented to end cap 6 , it is also for sealed hydraulic cylinder body 1 and pneumatic cylinder body 2;First is formed between first guiding end cap 7 and first piston 3 to exhale Suction muffler 11, second is oriented to formation second between end cap 8 and second piston 4 breathes air cavity 12.First piston 3 in hydraulic cylinder exists When oil-filled, by the first correcting for being oriented to end cap 7, First piston bar 5 is promoted to slide on the first guiding end cap 7;Air pressure Second piston 4 in cylinder, by the second correcting for being oriented to end cap 8, promotes second piston bar 6 to be oriented to second when inflation Slide on end cap 8.
An outage is set on the first described guiding end cap 7;A steam vent is set on the second described guiding end cap 8, Linked together with the gas-liquid holding vessel 9 with the clear device of prepressing type air by flexible pipe respectively;The described clear device of band prepressing type air Gas-liquid holding vessel 9 on an outage is set, a blowoff valve is installed on outage.When the First piston bar 5 in hydraulic cylinder is stretched out, The volume of the first respiratory gass intracavity reduces, and the fluid of the first respiratory gass intracavity can be passed through the outage on the first guide end lid, It is discharged in the gas-liquid holding vessel with the clear device of prepressing type air through flexible pipe, periodically can stores up the gas-liquid with the clear device of prepressing type air Deposit the opening of the blowoff valve on tank to drain the oil;When second piston bar in pneumatic cylinder stretches out, the volume of the second respiratory gass intracavity reduces, meeting By the fluid of the second respiratory gass intracavity by the steam vent on the second guide end lid, through flexible pipe the clear device of band prepressing type air is discharged to Gas-liquid holding vessel in, no matter how environment is badly also not plugged up.
Described First piston bar 5 and the position of the connection of second piston bar 6 is curved surface, First piston bar 5 and second piston It is that a contact carries out pressure transmission that bar 6 passes through, in the course of work, to the less demanding of coaxial precision.
Gas-liquid holding vessel 9 with pre-compressed air cleaner is for storing gas and the liquid that air cavity and sap cavity are leaked Body, while providing breathing air and space, the gas-liquid holding vessel with pre-compressed air cleaner for hydraulic cylinder and pneumatic cylinder body It is to adapt to adverse circumstances.
As shown in figure 1, when accumulator is after using some time, there is abrasion in the sealing on first piston 3, when quick During oil charging-discharging, have a small amount of fluid and take in the first breathing air cavity 11 from sap cavity, if the fluid revealed is excessive, can be from first Be oriented to end cap 7 outage be discharged in the gas-liquid holding vessel 9 with pre-compressed air cleaner by flexible pipe, due to sap cavity 13 it is gentle Chamber 14 is detached, is thus not result in that the fluid revealed is leak in air cavity.
In the same manner, there is abrasion in the sealing in second piston 6, and the gas in air cavity 14 can be leaked to the second breathing air cavity 12 In, if the gas revealed is excessive, band prepressing type air-filtering can be discharged to by flexible pipe from the steam vent at the second guiding end cap 8 In the gas-liquid holding vessel 9 of device, because sap cavity 13 and air cavity 14 are detached, thus it is not result in that the gas revealed leaks into sap cavity It is interior.
Preferred embodiment of the present utility model is the foregoing is only, and limits this utility model never in any form, For a person skilled in the art, this utility model can have various changes and modification.It is all in spirit of the present utility model Within principle, any change made, equivalent, modification, improvement etc., should be included in protection domain of the present utility model Within.Therefore, protection domain of the present utility model should be defined by the protection domain of claims.
