Abstract
Disclosed is a nitrogen inflation gun, belonging to the technical field of designing and manufacturing of nitrogen inflation gun for tyres. The inner gun body is provided with a nitrogen inlet tube and a compressed air hose, a scavenging valve and an operation valve core, etc. A nitrogen inlet pipeline and a compressed air line are controlled and regulated by the scavenging valve, the nitrogen inlet pipeline is on when the aeration valve rod is pushed; the compressed air line is on when the aeration valve rod is exhausted. The utility model has simple structure and professional design, combines the functions of tyre evacuation and nitrogen charging together, making it convenient and fast to use the gun, and is labor-saving and time-saving without wasting nitrogen.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of nitrogen charge gun.
Background technology
At present, be used for that the tire of aircraft, luxury car is many to replace charge of air with nitrogen.Can reduce the tire heating like this, reduce the rate of blowing out, reduce the tire oxidation rate.Present inflation is to utilize vacuum pump with air extraction in the tire earlier.Utilize nitrogen qi of chong channel ascending adversely rifle to put on the air complicated operating process again.In addition, also have a kind of nitrogen that utilizes abroad, vacuumize, carry out inflated with nitrogen again, wasted nitrogen so again according to Wen's principle, neither be very desirable.Also do not use in practice at present with the utility model like products.
Summary of the invention
The purpose of this utility model provides the nitrogen charge gun that a kind of exhaust and inflated with nitrogen function are integrated.It is quick to be easy to use.Overcome the problem of existing method complicated operation.
Structure of the present utility model is as shown in drawings: the entrance pressure air pipe that contracts is arranged in the bottom of rifle body, into nitrogen tube is arranged in it, on the top of advancing nitrogen tube one scavenge valve is arranged.Scavenge valve top has one to handle spool, and a side of spool has one to handle hand pressure handle.On the top of rifle body one degassing button is arranged.In rifle body top one side one cock wheel nausea pipe is arranged.Opposite side has a compression indicator.Of the present utility model advance nitrogen tube and entrance pressure contract air pipe respectively through scavenge valve, handle spool etc. and be connected with degassing button, cock wheel nausea pipe.Method of work of the present utility model is: when giving inflation of tire, at first will then the cock wheel nausea pipe on rifle body top be received on the inflation of tire mouth with the air exhaustion in the tire to normal pressure, will advance nitrogen tube and be connected on the nitrogen gas cylinder outlet nozzle.Open degassing button then, pull out scavenge valve, press the manipulation hand pressure handle.At this moment, the entrance pressure air duct that contracts is open-minded, and pressurized air is advanced along pipeline, discharges from degassing button, forms negative pressure because speed is high, with air extraction in the tire, and the interior formation of tire vacuum, gas bleeding is discharged by degassing button.Subside fully until tire.Vacuumize end.Then, will handle hand pressure handle and unclamp, close degassing button, advance scavenge valve.And then depress the manipulation hand pressure handle.At this moment, it is open-minded to enter the nitrogen road, and nitrogen enters tire along advancing nitrogen tube, process scavenge valve, handling spool.Finish the inflation operation.Advancing the route and the pressurized air turnover route of nitrogen and controlled by scavenge valve, pull out scavenge valve, is to open pressurized air lines, and advancing scavenge valve is the closes compression air routing, opens into nitrogen route.The utility model is simple in structure, and is reasonable in design, and two functions of nitrogen combine with filling into to make discharging tire air, and device becomes one.It is convenient especially to use.It is a kind of desirable nitrogen inflatable appliance.

The specific embodiment
The one entrance pressure air pipe (2) that contracts is arranged in the bottom of rifle body (3).Into nitrogen tube (1) in contracting air pipe, entrance pressure is arranged.One scavenge valve (4) is arranged on the top of two pipes.Have one to handle spool (5) on scavenge valve top.The right-hand member of spool has one to handle hand pressure handle (9).At rifle body top one degassing button (7) is arranged.In rifle body top one side one cock wheel nausea pipe (8) is arranged, one compression indicator (6) is arranged at opposite side.Entrance pressure contract air pipe and advance nitrogen tube through scavenge valve with the manipulation spool be connected with top degassing button and cock wheel nausea pipe.
Claims (1)
- The nitrogen charge gun, it is characterized in that having the entrance pressure air pipe (2) that contracts in the bottom of rifle body (3), into nitrogen tube (1) in contracting air pipe, entrance pressure is arranged, one scavenge valve (4) is arranged on the top of two pipes, have one to handle spool (5) on scavenge valve top, the right-hand member of spool has one to handle hand pressure handle (9), at rifle body top one degassing button (7) is arranged, in rifle body top one side one cock wheel nausea pipe (8) is arranged, one compression indicator (6) is arranged at opposite side.
