Abstract
The utility model provides an inflation valve, which comprises a shell, an air inlet, an air outlet and a cavity. The utility model is characterized in that a sphere, a spacing needle and a fixing sleeve are arranged in a cavity arranged in the air inlet. The utility model has the advantages of simple structure, low cost, convenient operation, etc.
Description
The utility model relates to a kind of gas of inflating and chews device, especially is made up of metal shell, air inlet/outlet, cavity, rubber ring.
Selling in the market that gas on the pump chews is exactly this structure, mainly is made up of metal shell, air inlet/outlet, cavity, rubber estate.When gas is chewed and engaged by the object of being inflated, when engaging with the inflation of tire mouth, the gas in the object can be chewed outward along gas and spill, and influences to inflate speed and quality.
The purpose of this utility model provides a kind of pump gas and chews, and it can carry out unidirectional air inlet easily, accelerates the speed of inflating.
For achieving the above object, solution of the present utility model is, being positioned at suction port is shape cavity place, half garden and is provided with a garden ball, by the fixing position-limited needle of fixed cover, and the radius size of suction port inner chamber half garden shape is less than the radius size of garden ball, the residing position of position-limited needle just makes the garden ball that enough activity spaces are arranged, can rotate freely motion, be easy to again be rebounded by the gas that the air outlet is located, the cavity gas inlet plug that is half garden shape is extremely reached the one-way sealing effect, guarantee that gas can only advance from suction port, return out and can not overflow from suction port.
Owing to adopted garden ball and position-limited needle in the above-mentioned solution, can carry out unidirectional air inlet very easily, this is simple in structure, and cost is low, the convenient use.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model, and 1 chews body for gas among the figure, and 2 is suction port, and 3 is garden ball piston, and 4 is fixed cover, and 5 is position-limited needle, and 6 is the air outlet, and 7 is cavity.
When using, pressurized air by suction port 2, went here and there garden ball piston 3, enter air outlet 6, finally go into to place with gas requirement.When 6 places, air outlet have certain pressure and during greater than suction port place pressure, pressurized gas in the cavity floats garden ball piston and is attached in the cavity that is half garden shape of suction port, gas inlet plug is dead, the function that gas is chewed is unidirectional inflow, in other words, pressurized gas can only enter, and can not overflow in the chamber automatically.
The utility model patent has simple in structure, and cost is low, and is practical and convenient, can be widely used in the inflating of the inflating of vehicle tyre, balloon, and daily life in need on the compressed-air actuated article and implement.
Claims (3)
1, a kind of inflating chewed, and comprises housing, air inlet/outlet, cavity, rubber ring, it is characterized in that being positioned at suction port and is shape cavity place, half garden one garden ball, position-limited needle, fixed cover are set.
2, chew according to said the inflating of claim 1, it is characterized in that the suction port inner chamber is half garden shape, and radius size is less than garden radius of a ball size.
3, chew according to claim 1 or 2 said inflating, it is characterized in that position-limited needle is arranged between garden ball and the air outlet, position-limited needle can rotatablely move the garden ball, the garden ball is blown afloat.
