Abstract
Disclosed is a safety valve of inner tube valve. The safety valve of inner tube valve has the structures of double-spring, double-valve-body and plug-type valve inside. The safety valve of inner tube valve can inflate safely. When the air pressure in the inner tube is too big, the safety valve of inner tube valve can automatically discharge air, until the set pressure value of the inner tube is achieved, air discharging is stopped. The safety valve of inner tube valve can keep tyre using in the best inflating state. The utility model has the advantages of long service life and safety assurance. The safety valve of inner tube valve is suitable for bicycle, tricycle, jinrikisha, automobile and other vehicles needing inner tube inflation.
Description
The utility model technical field belongs to the annex that is used for tire valve, particularly a kind of inner tube valve safety valve.
The inner tube of a tyre of tires such as bicycle automobile, general inflation is undertaken by valve gear, in gas replenishment process or in the running process, if the air pressure of the inner tube of a tyre is higher or lower than the standard atmosphere pressure of inflation, tire is shortened dramatically working life, when surpassing the limit air pressure that inner tube of a tyre regulation born because of the air pressure of the inner tube of a tyre sometimes, the inner tube of a tyre can break, or the hose of valve inside (bicycle) breaks, and inner tube of a tyre gas is overflowed, and has a strong impact on normal use.
The gas that can overflow automatically when surpassing authorized pressure when the purpose of this utility model provides the inflation of a kind of inner tube of a tyre surpasses and presses the inner tube valve safety valve of protecting.
Task of the present utility model is finished with the following methods: the valve body of valve is screwed on one's body the inner tube valve through screw thread.Valve body endoporus at valve is put into piston valve core and gasket seal.Put into valve core spring and valve inside spring respectively at piston valve core outer circumferential side and endoporus.The air pressure adjustment screwed pipe is through the spin valve body of valve of screw thread.Valve inside is through the screw thread piston valve core that spins.Between valve inside and the valve inside spring valve inside ball is arranged, locking nut connects with valve inside through screw thread.Central part has the pneumatic head of vent to be screwed on the valve inside through screw thread.Valve inside and piston valve core central part all have vent, and there is vent at the valve body perisporium place of valve.
The inner tube valve safety valve can make inner tube of a tyre inflation just in time reach regulation air pressure when the inner tube of a tyre is inflated, and can not indicate under-inflation or overinflation because of no detector and make air pressure too high.Make tire pressure at optimum shape degree, tire is guaranteed working life, reduce the tire irregular wear, prolong tire working life.Simultaneously under steam, can not break, guarantee safe in utilization because of tire pressure is excessive.

Fig. 2 is a pneumatic head inflation work schematic representation
Below in conjunction with accompanying drawing this inner tube valve safety valve is described in further detail: inner tube valve body (1) passes the inner tube of a tyre (2), and valve packing ring (3) is fastening with hexagon nut (4).It is fastening with round nut (6) that inner tube valve body (1) is passed rim (5) again.The valve body (9) of valve is equipped with O RunddichtringO (7) through being threaded on the inner tube valve body (1) between them.There is vent (23) at valve body (9) the perisporium place of valve, and 1 to 6 of quantity all can.At valve body (9) endoporus of valve pack into gasket seal (8), piston valve core (11), valve core spring (10) and valve inside spring (12).Air pressure adjustment screwed pipe (14) is through valve body (9) endoporus of screw thread precession valve.Valve inside (15) has valve inside ball (13) through screw thread precession piston valve core (11) endoporus between valve inside spring (12) and valve inside (15).Locking nut (16) precession valve inside (15), and clamping piston formula spool (11).Gapped between outer, the inner circle wall of the valve body (9) of piston valve core (11) and valve, when overflowing gas, can move mutually by valve.The centre has the pneumatic head (17) of vent to be tightened on the valve inside (15) through screw thread.Valve inside (15) and piston valve core (11) central part all have vent.Pneumatic head (17) can be lineal shape or bending, present embodiment system elbow at an angle of 90.In order to prevent that dust, sand grains from falling in the vent, at the valve cap (19) of the end precession band O RunddichtringO (18) of pneumatic head (17).When inflation, as shown in Figure 2, corrugated connecting tube (21) locking is connected on the pneumatic head (17) with attaching nut (20), on bellows (21), be with rubber pipe (22).At this moment, can supply gas, be sent to the inner tube of a tyre through safety valve to rubber pipe (22).
The working principle of this valve is such: with pressure regulate roof pressure power that screwed pipe (14) will act on the valve core spring (10) on the piston valve core (11) be adjusted to the inner tube of a tyre given standard atmosphere pressure value.When the gas pressure of the inner tube of a tyre (2) was in the specified standard air pressure range, gas acted on power on the piston valve core (11) less than the roof pressure power of valve core spring (10), and safety valve is in closed condition.When the gas pressure of the inner tube of a tyre is higher than standard atmosphere pressure, gas acts on power on the piston valve core (11) greater than the roof pressure power of valve core spring (10), piston valve core (11) is backed down by gas, safety valve is in opening state, carry out exhaust, make the pressure of the inner tube of a tyre drop to standard atmosphere pressure following time, the power on the piston valve core (11) of acting on is less than the pressure of valve core spring (10), and piston valve core (11) is closed again.In the safety valve, carry out for the inner tube of a tyre (2) inflation through valve inside (15).Rotary valve core (15) is regulated the elastic force of valve inside spring (12), is transferred to make inflation convenient, ends when inflation back valve inside (15) is air tight.The inflation mode can be carried out with pump or air pump.Valve inside (15) and piston valve core (11) locking, prevent valve inside (15) rotation with locking nut (16).When the inner tube of a tyre is inflated, pressurized air unseat the valve core ball (13), gas enters the inner tube of a tyre through piston valve core (11) breathing pipe, when stopping to inflate, valve inside ball (13) is under valve inside spring (12) effect, make valve inside ball (13) withstand the vent of valve inside (15), safety valve is in closed condition.
The accompanying drawing 1 of present embodiment is the inner tube valve safety valve of bicycle use.The inner tube valve safety valve structure principle of other vehicle is identical.
This inner tube valve safety valve can be suitable for bicycle, tricycle, rickshaw and automobile, and needs to use other vehicle of inner tube of a tyre inflation to use.
