With the present utility model, the aerating is neither insufficient nor excessive.
Description
Technical field
The utility model relates to a kind of controlled tire safety inflator of highpressure, belongs to the Tyre inflating device
Technical field.
Technical background
Vehicles such as bicycle are after a period of time of riding, and the air pressure in the tire can descend, and can cause riding effort and tire premature breakage need in time to give Tyre inflating usually.People often use apparatuses such as pump or inflator to come to Tyre inflating.When using conventional charger (as pump, inflator etc.) to give Tyre inflating, air pressure in the tire is often judged by people oneself, people constantly push tire with hand, judge according to the soft or hard degree of tire whether the air pressure in the tire is suitable.Yet judge that in this way the tyre pressure size can bring inconvenience to the operator, the one, tire is often very dirty, can make dirty hand or gloves; The 2nd, judge that by experience personal factor is big, often judge not accurate enough, especially women, old man, child, gas is beaten to have lacked and is not had due effect, plays tire many can explode.
Summary of the invention
Goal of the invention of the present utility model provides the Tyre inflating device of the controlled safety of a kind of highpressure.
The utility model adopts following technological scheme to solve its technical problem: the utility model is a kind of tire safety inflator, it comprises main inflator and gas tank, main inflator and gas tank gas are communicated with, be provided with one-way cock at the connection jointing, gas tank diapire or sidewall are provided with air pipe, on gas tank, be provided with a relief valve device, relief valve device comprises base, shell, the valve control unit, shell is provided with bleeder port, and base is located on the gas tank, shell is located on the base, also be provided with gas port on the base, gas port and gas tank are communicated with, and the top of gas port is provided with valve port, the valve control unit is positioned at the inner face of shell, it comprises bonnet, valve rod and spring, bonnet are positioned at the top of valve rod, and match with valve port in the top that is positioned at valve port, the end of valve rod passes shell, and spring is placed on the valve rod.
When using the utility model to give Tyre inflating, air pressure in the cylindrical shell is higher than the air pressure of gas tank, and one-way cock is opened, and pressurized gas enters gas tank, the air pressure of gas tank also increases thereupon, and gas has just entered in the tire by air pipe when its air pressure is higher than the tire internal air pressure.In above-mentioned gas replenishment process, after the air pressure of gas tank reached a critical atmospheric pressure value, gas will promote to be pressed in the bonnet of valve port, and bonnet drives valve rod and up slides together, and the spring on the valve rod also is compressed at this moment.After bonnet is backed down, gas just sprays along the slit at bonnet and valve port place, exhaust port from the casing wall discharges again, the interior gas pressure intensity of gas tank this moment will reduce rapidly, because the restoring force of spring and the deadweight of bonnet and valve rod, bonnet and valve rod will be close to valve port, when air pressure subcritical atmospheric pressure value, bonnet and valve port closely cooperate, and gas just can not overflowed from here.The weight of critical atmospheric pressure value recited above and bonnet and valve rod and the spring ratio of spring self are relevant.Can select the position of spring or adjusting block to regulate critical atmospheric pressure value as required.
Compared with prior art, the utlity model has following advantage:
Because the utility model is provided with relief valve device, when using to Tyre inflating, in case the air pressure of gas tank is too high promptly when it reaches a certain critical atmospheric pressure value, bonnet is just backed down, gas just sprays along the slit at bonnet and valve port place, exhaust port from the casing wall discharges again, and the gas pressure intensity in this moment gas tank will be reduced to rapidly and be lower than this critical atmospheric pressure value, also just is lower than the pressure of gas in the tire.When bleeder port is a series of aperture along enclosure axis to being spaced, when bonnet and outer casing inner wall closely cooperate, will be if the gas pressure intensity in the gas tank is high more with the opening more of bonnet top, it is many more to participate in the aperture that loses heart this moment, and pressure just falls sooner.This moment, gas just can not continue to enter into tire, and the pressure of the gas in the tire just can not continue to have increased yet so, and the highpressure of tire has been avoided because excessively inflation and cause blowout with regard to being controlled; When gas during from the ejection of the slit of bonnet and valve port, can be attended by sound simultaneously, it reminds people's Tyre inflating to get well as chimes of doom.In the time of the Tyre inflating deficiency, bonnet and valve port closely cooperate, and gas can not overflowed from valve port, and the inflation that people's door can be relieved is till the effusion sound of hearing gas.Thereby neither can under-inflation when using the utility model to inflate, can hyperinflation yet.
