Abstract
When the prior autocycle tyre is inflating, excessive inflation leads to an autocycle tyre burst and when the wheel is running, the high air pressure in an autocycle tyre caused by raised temperature also leads to the tyre burst, which is also an important factor that causes highway traffic accident. The utility model provides an automatic decompression anti-burst safe air faucet for the autocycle tyre, which is made up of a push-pull rod, a gas inlet pipe, a gas sealing spring, an exhaust pipe, an exhaust spring, a groove ring, an exhaust seal rubber ring, an exhaust hole, a gas sealing seal rubber ring, an gas sealing bowl, a gas faucet cover with a hole and a clip spring piece. The utility model can give out part gas before the air pressure in the autocycle tyre achieve a critical point of tyre burst to make the air pressure in the autocycle tyre go back to a normal value, consequently the traveling hidden trouble caused by the tyre burst is eradicated.
Description
One, technical field
The utility model relates to a kind of valve, particularly a kind of automatic decompression explosion-proof safety nozzle of motorcycle tire.
Two, background technique
As everyone knows, motorcycle tire when inflation,, can cause and blow out: during the wheel operation, cause the rising of motorcycle tire internal air pressure, also can blow out that this also is to cause factor for traffic accidents because temperature raises if inflate excessively.
Three, model utility content
The technical deficiency of not having security limitations at existing motorcycle tire internal air pressure, the utility model provides a kind of can emit proper amount of gas automatically before the motorcycle tire internal air pressure reaches the transition point of blowing out, make the motorcycle tire internal air pressure return to the automatic decompression explosion-proof safety nozzle of motorcycle tire of normal value.
The scheme that solves the utility model technical problem is: automatic decompression explosion-proof safety nozzle of motorcycle tire is made of pull bar, suction tude, envelope air spring, outlet pipe, exhaust spring, grooved ring, exhaust sealing cushion rubber, exhaust port, envelope hermetic seal rubber ring, envelope gas bowl, gas nozzle cap with holes and jump ring sheet.Outlet pipe and suction tude are to be threaded.The suction tude lower end mouth contacts with the envelope hermetic seal rubber ring.Exhaust spring is enclosed within the bottom of suction tude, and the exhaust sealing cushion rubber is housed in the circular groove of grooved ring lower surface.The bottom that grooved ring is enclosed within suction tude can be free to slide in the bottom of suction tude.The elastic force of exhaust spring compressing grooved ring makes the exhaust sealing cushion rubber be pressed in the looping pit upper edge of outlet pipe, with the sealed tire compressed air.Be higher than at outlet pipe on the sidewall of grooved ring and have exhaust port.Pull bar runs through suction tude, and the top of pull bar is provided with a rectangular card reed, and the part between the rectangular card reed of pull bar and the thick tube bottom of suction tude is with the envelope air spring.Spring upper end and the welding of rectangular card reed, the thick tube bottom welding of lower end and suction tude.The pull bar lower end is provided with screw thread and stretches out the suction tude lower end.Envelope gas bowl center have one with the screw of pull bar lower end threads engaged, the screw degree of depth is 1/3 of ventilation bowl thickness, this hole combines with the pull bar lower end, be stained with the envelope hermetic seal rubber ring in the envelope gas bowl, the envelope air spring should be 3N to the pressure of jump ring sheet, exhaust spring is to the pressure F=P * S * W of grooved ring, wherein, and the highest atmospheric pressure that P can bear for motorcycle tire inside; S is the horizontal area of the minimum annular space between thin tube of suction tude and the outlet pipe; W is a safety factor, gets 1/2.The gas nozzle cap with holes that is with suitable for reading of suction tude, its end has the pore that a diameter is 1mm.The gas nozzle cap suitable for reading and with holes of suction tude is with screw-thread fit.
When with inflator when motorcycle tire is inflated, to pressing down, pull bar promotes to seal the gas bowl downwards makes the envelope hermetic seal rubber ring leave the air inlet mouth of pipe to the inflator valve with pull bar, high-pressure air charges into from suction tude.When atmospheric pressure in the motorcycle tire surpasses the normal pressure value, the pressure that air produced in the motorcycle tire upwards backs down grooved ring and exhaust sealing cushion rubber, air will enter space, exhaust spring place from the minimum annular space between thin tube of suction tude and the outlet pipe in the motorcycle tire, and discharge by exhaust port.When atmospheric pressure in the motorcycle tire was got back to the normal pressure value, grooved ring and exhaust sealing cushion rubber moved downward under the effect of exhaust spring, sealed the minimum looping pit between thin tube of suction tude and the outlet pipe, and exhaust is stopped.
Because the utility model can automatic vent, decompression when the motorcycle tire internal air pressure is too high, therefore eradicated because of too high the blowing out of causing of motorcycle tire internal air pressure, improved the safety coefficient of driving.
