Description
Technical field
Device when gas and large-scale cylinder need fast return action in quick drained pipeline when the present invention relates to the venting of a kind of automobile tire, especially relates to the fast-discharge valve in a kind of off-the-highway tire inflating-pressure releasing system.
Background technique
At present, the domestic fast-discharge valve having partial pneumatic element manufacturer to produce gas control, but there is no automatically controlled fast-discharge valve, and during automobile inflation/deflation, require it is automatically controlled centralized control of being just convenient to, now also there is the automatically controlled fast-discharge valve of indivedual manufacturer production diaphragm types, but exhaust port latus rectum during fast row is little, when pipeline is long, can not the residual air of fast evacuation pipeline, thus cause tire valve simply not turn off thoroughly fast, especially high pressure is more obvious, at 600Kpa ~ 650Kpa, power cutoff, occasional occurs closing constantly, and complex structure, cost is higher.
Patent documentation (CN201100437Y) discloses a kind of automobile tyre central inflation-deflation over-flow shuttle valve, its compact structure, and volume is little, be convenient to assembling, release handle be housed, inflation/deflation speed can be regulated arbitrarily, but its manufacture cost is higher, is not suitable for mass production; In Argentine Col Ven SA patent documentation (CN102089558A) disclosed in it, describe a kind of in order to inflation, the pressure controlled three way valve device keeping inflated condition and deflation status, this equipment comprises the plunger axially run through by gas-entered passageway, wherein, the suction valve that this gas-entered passageway is promoted by spring normally cuts out.The outer side wall of this plunger comprises O type ring and extends to groove wherein, so that near the stepped parts of this groove to limit this plunger stroke, and keep an exhaust loop close to the exhaust port formed in the sidewall of this valve body, the valve of this result equally also improper centralized control and manufacturing being used for automobile inflation/deflation is produced.
In addition, another on the lathes such as punching press, require the quick acting of cylinder energy, produce larger impact force, also require to drain fast one side gas of cylinder, be convenient to cylinder piston and be rapidly to the action of gasless one end under the gas effect of another side, the gas control type fast-discharge valve being also at present and other valve combinationally use.
Summary of the invention
Object of the present invention is just to overcome the large not and high in cost of production problem of existing exhaust latus rectum, provides a kind of automatically controlled fast-discharge valve newly, guarantees the gas in fast evacuation pipeline or make cylinder quick acting.
Solving the problems of the technologies described above the technical conceive taked is, present published patent of invention is ¢ 8 ~ ¢ 10 because its structural restriction latus rectum is less, design a kind of solenoid valve of big orifice, can reach ¢ 15 when volume does not increase, that flow just expands original 2.25 times ~ 3.5 times to.Adopt ripe fast-discharge valve structure, by rational design, replace controlling source of the gas with a pilot solenoid valve.Working procedure specific as follows and principle as follows:
When coil obtains electric, dynamic iron core moves upward and turns off the central through bore of static iron core under the effect of electromagnetic attraction and spring, cylindrical A cavity (suction port of valve) on valve body, in cylindrical B cavity (air outlet of valve), gas can enter in truncated cone D inner cavity, due to cylindrical A cavity (suction port of valve), the force rate rubber ring self gravitation upwards that cylindrical B cavity (air outlet of valve) place's gas produces jointly, the downward power three sum of the downward elastic force that spring produces and the generation of truncated cone D cavity place gas is little, rubber ring is downward fast, cut off cylindrical A cavity (suction port of valve), passage between cylindrical B cavity (air outlet of valve) and cylindrical E cavity (relief opening), thus turn off relief opening fast, it is now off working state.Gas circuit now between cylindrical B cavity place with cylindrical A cavity place is communicated with.
When solenoid valve power-off, when coil must not be electric in this valve, dynamic iron core turns off cylindrical A cavity (suction port of valve) on valve body under the effect of deadweight, cylindrical B cavity (air outlet of valve) be communicated with aperture between truncated cone D cavity, in truncated cone D cavity, gas is drained by the exhaust hole on the dynamic air vent of iron core both sides and the central through bore of static iron core and coil locking cap, due to cylindrical A cavity (suction port of valve), the power upwards that cylindrical B cavity (air outlet of valve) place's gas produces enough overcomes the power of rubber ring self gravitation and spring, rubber ring fast upwards, be communicated with cylindrical A cavity (suction port of valve) on valve body, cylindrical B cavity (air outlet of valve) and the cylindrical E cavity (relief opening) on exhaust nozzle, thus cylindrical A cavity (suction port of valve) of draining fast, the gas at cylindrical B cavity (air outlet of valve) place, it is now working state.
The technical solution used in the present invention is: a kind of automatically controlled guide's fast-discharge valve, comprises valve body, the first spring, an O type rubber seal, solenoid valve seat fixed plate, dynamic iron core, coil, static iron core, coil locking cap, the 2nd O type rubber seal, the first circlip for hole, the second circlip for hole, silencer sheet, exhaust nozzle, rubber ring, the second spring, the annexation of above-mentioned parts is: be connect matrix with valve body, its left upper end is followed successively by: coil locking cap is fixed on static iron core by screw thread, and the fixing coil be extremely enclosed within static iron core, dynamic iron core is in static iron core inner chamber, first spring is contained on dynamic iron core, in static iron core inner chamber, one O type rubber seal is contained in static iron core produces with valve body and seals, solenoid valve seat fixing board card is on static iron core and be fixed on valve body by two countersunk screws are not shown in FIG., be followed successively by from top to bottom in valve body intermediate cavity: the second spring to be contained on valve body between blind hole and rubber ring, 2nd O type rubber seal is contained on exhaust nozzle groove and produces sealing between it and valve body, silencer sheet or silencing apparatus are contained in exhaust nozzle endoporus fixing dead by the second circlip for hole by screw thread, first circlip for hole is contained on valve body intermediate cavity inside groove and is used for fixing exhaust nozzle.
The technique effect adopting technological scheme of the present invention to bring is:
1, structure is simple, and cost is low, and in the same unit time, exhaust is more, effective;
2, improve on existing fast-discharge valve basis, reliable performance;
3, take rubber ring as piston, sealing is reliable, and be swift in motion, exhaust port latus rectum adds much larger than diaphragm type, and volume does not increase.
