Abstract
The utility model discloses an inflating valve, and basically and integrally improves the inflating valve of bicycles and light vehicles. A valve inside and the inflating valve body are designed to form an integral body, and the inflating valve is sealed by that a valve core is abutted in the inner conical hole of the body by the air pressure of an inner tyre. Thus, parts are reduced, the sealing reliability is increased. The inflating valve has the advantages of theft prevention and labor saving when a tyre is inflated.
Description
The utility model belongs to inner tube of vehicles and seals gas-tight technical field.It is the improvement of application 89218541,4 laborsaving automatic dustproof valve insides.
At the unified English valve nozzle of producing (seeing 429 pages of bicycle application manuals) of 18 valve nozzle factories of China.The shortcoming of this valve nozzle is that small hose is not durable, easily gas leakage.Secondly complex structure influences the reduction of cost.The fact is that this product is eliminated by countries in the world.
Order of the present utility model is that design a kind ofization valve inside and valve nozzle are the novel valve nozzle of one, has solved the inflation effort, stops up easily and has lost heart slowly and complex structure and other problems.
The utility model is by body (1), and base (2) and spool (3) are formed, and the material of spool is a rubber.The material of body and base is copper or duroplasts.
Pressurized air is pushed spool (3) open and via the slit of the valve of spool and body (1) from inlet hole (4) during inflation, passes base endoporus (5) and flows into the inner tube of a tyre.The tire internal air pressure is pressed against spool unlikely gas leakage on the internal taper hole of body (1) in base endoporus (5) rushes at spool (3) bottom at ordinary times.This is unique possible air-leak section.Actual product shows once unnecessary additional gas again of inflation.
The utility model has following five big advantages: (1) inflation power only reaches 1/3 of old valve nozzle.(2) sealing gland is reliable.(3) but economical with materials simple in structure 33%, in man-hour 43%, (4) are unlikely stolen, the thief can't extract.(5) can survey the tire internal air pressure.Other any valve nozzles all can't be surveyed air pressure.
The valve nozzle and the inner tube of a tyre (6) bonding during installation.Nut (7) compresses the packing ring and the inner tube of a tyre.The steel ring (8) that passes wheel can use.
Patent gazette through consulting between 1988 to 1994 does not all have similar patent application.
Claims (2)
1, a kind of valve cock, form by valve body (1), base (2) and spool (3), it is characterized in that valve body (1) is to collect old-fashioned valve cock and the mouth body is an one, base (2) is installed in the inside of body (1), and taper valve core (3) is arranged in the internal taper hole of body (1).
2, a kind of valve cock according to claim 1 is characterized in that the material of spool (3) is a rubber, and the material of body (1) both can adopt the brass material, also can use plastics.
