Abstract
The utility model relates to a direct air pressure inflating valve, and belongs to a one-way valve. The direct air pressure inflating valve comprises a valve seat, an inflating valve and a locking cap. The direct air pressure inflating valve is characterized in that the baffle plate of the upper portion of the valve seat is provided with an air inlet passage, and a hollow cavity formed by the baffle plate and the lower end of the inflating valve is provided with a back valve. The direct air pressure inflating valve the advantages of easy and convenient inflation in four seasons, high sealing performance, long service life, wide application scope, safety, good antitheft performance, etc., and is especially suitable for being installed on various inflating tyres to use.
Description
The utility model relates to a kind of direct pneumatic-typed valve cock, belongs to one-way valve, is particularly suitable for dress usefulness on all kinds of pneumatic tires.
The traditional valve cock of bicycle in the past, form by valve seat, pin type valve, valve inside, locking cap, though can finish the work, but because valve inside often is in and is subjected to rigid oppression state, and cause breakage to cause gas leakage, be enclosed within rubber adhesion in the summer aged deterioration on the valve inside simultaneously, cause working life short; Be not easy to throw into gas winter, often freeze together, need to take out and to put into after thawing pretty troublesomely again, make troubles to life with valve inside; Need when and for example automobile tyre is inflated just can inflate with plunger, very inconvenient, just because of there are above-mentioned many shortcomings in traditional valve cock, it is further perfect to still need.
The purpose of this utility model is to provide a kind of long service life, summer in winter inflation all easily, the valve cock that all is suitable for of good leak tightness, all kinds of pneumatic tire.
The purpose of this utility model realizes by the following technical solutions, is made up of valve seat, valve cock and locking cap, has gas-entered passageway on its described valve seat upper baffle plate, is provided with check valve in the formed cavity of dividing plate and valve cock lower end.
Described gas-entered passageway is to overlook the groove that is cross.
Described check valve is the check valve block of being made by ABS plastic.
The utility model compared with prior art, owing to adopted the check valve block and on the valve seat upper baffle plate, had the technical measures of gas-entered passageway, and through evidence have that four seasons inflations is easy and convenient, good leak tightness, long service life, Applicable scope is wide, safety, advantages such as theftproof performance is good are implemented easily simultaneously, are beneficial to and apply.
Figure is a main TV structure schematic representation of the present utility model.
Embodiment of the present utility model is described in conjunction with the accompanying drawings, valve seat 1 with brass through the machining moulding, having the groove that is cross on its upper baffle plate in length and breadth is gas-entered passageway 6, the check valve block 3 that the ABS plastic plate is made is placed on it, sealing gasket 4 places the upper end of valve seat 1, and valve cock S is loaded on the valve seat 1 by locking cap 2.
When inflation, pressurized air enters inner chamber from valve cock 5 and be driven into tire through gas-entered passageway 6 around check valve block 3, when being charged to standard pressure, under the compressed-air actuated effect of check valve block 3 in tire its jack-up being sealed valve cock 5 air passage port behind the shutoff source of the gas, thereby guarantee non-leakage gas.
Claims (3)
