Abstract
The utility model relates to a piston-type valve for a small-size inflating tyre. The piston-type valve for a small-size inflating tyre can be widely used for the tyres of small-size vehicles of a bicycle, a manpower vehicle, a tricycle, etc. The piston-type valve for a small-size inflating tyre is different from the existing strain type valve, and the piston-type valve for a small-size inflating tyre adopts a piston type. The piston-type valve for a small-size inflating tyre is composed of a valve rack 1, a piston rod 2, a piston 3, and a sealed stopper 4. The utility model has the advantages of good tightness, labor saving, long service life, and simple processing technology. The piston-type valve for a small-size inflating tyre can substitute the existing strain type valve.
Description
The utility model relates to and be used for small-sized airtyred valve cock, can be widely used on the dillies such as bicycle, rickshaw, tricycle.
Widely used valve cock is a tension-type on this type of vehicle now, and its seal ring and suction valve are same emulsion tubes.During air inlet, gas also must overcome the tension force of emulsion tube, therefore inflates and requires great effort very much.In addition, emulsion tube is thinner, and is easily aging, especially when the temperature cataclysm, and air leakage failure very easily.Use such valve cock, just needed inflation again in general several days, otherwise, easily make the cover tire fracture by the interior air pressure deficiency that gas leakage causes.
The purpose of this utility model is to design a kind of valve cock of favorable sealing property, and inflate laborsaving, long service life.
The utility model is that the design by piston type achieves the above object.It is by valve frame 1, piston rod 2, and 4 four parts of piston 3 and sealing plug are formed.Valve frame 1 is installed on the valve seat of the inner tube of a tyre, sealing plug 4, and piston 3 and piston rod 2 are installed in the valve frame 1, and piston 3 is fixed on the piston rod 2, and when inflation, they can move along the axis of valve frame.(seeing accompanying drawing)
During inflation, gas at inflation inlet B place, overcomes the internal air pressure of tire by the inlet A of valve frame, washes piston 3 open, by the center hole of sealing plug 4, unimpededly enters the inner tube of a tyre.After inflation finishes, because interior air pressure is greater than outer air pressure, piston 3 will have been blocked inflation inlet B along the axis of valve frame, forbid gas leak.In order to guarantee good sealing property, valve frame 1 is inclined-planes with the sealing contact surface of piston 3, sealing plug 4 and piston 3 are two individual components, piston 3 can be made by the monoblock elaxtic seal, effective sealing chi thickness of sealing plug 4 is not subjected to the restriction of piston 3, so not only increase sealing effect, and be difficult for wearing out, prolonged the life-span.Valve frame 1 and piston rod 2 can be made by brass, iron or plastics, and sealing plug 4 is made by plastics or rubber.
Piston type valve cock of the present utility model, except above-mentioned advantage, and processing is simple, can replace existing tension-type valve cock.
Claims (4)
1, a kind ofly be used for small-sized airtyred piston type valve cock, it is characterized in that this valve cock by valve frame 1, piston rod 2, piston 3, sealing plug 4 totally four parts are formed; Valve frame 1 is installed on the valve seat of the inner tube of a tyre, and sealing plug 4 and piston 3, piston rod 2 are installed in the valve frame 1; The inflation inlet B of valve frame 1 is by the unidirectional air inlet of piston 3 controls, and sealing plug 4 and piston 3 are two independently parts.
2, valve cock according to claim 1 is characterized in that piston 3 is fixed on the piston rod 2, can be along moving radially in the valve frame during inflation.
3, valve cock according to claim 1 is characterized in that sealing plug 4 made by plastics or rubber, and the size of sealing plug 4 is not limited by piston 3.
4, valve cock according to claim 1 is characterized in that the valve frame 1 and the sealing contact surface of piston 3 are inclined-planes.
