Abstract
The utility model discloses a multifunctional inflator valve assembly which comprises a housing and a transition valve. The housing is internally provided with an air inlet channel and an axle hole which are communicated. Two ends of the transition valve are provided with different kinds of valve heads. The transition valve is inserted into the axle hole. A sealing ring is equipped between the transition valve and the housing. The lower end of the housing in screw jointing with an end cap. The transition valve downwards passes through the end cap and is equipped in the housing through the end cap. The multifunctional inflator valve assembly is advantageous in that only screwing-down of the end cap, pulling-out of the transition valve and insertion into the axle hole are required when transition of the valve head is required. The multifunctional inflator valve assembly further has the following advantages: simple operation, simple structure, reliable connection, small volume and long service life. Furthermore because the cross section of the sealing ring between the transition valve and the housing is square, and the middle parts of four surfaces of the sealing ring are respectively provided with a groove, the multifunctional inflator valve assembly has dual sealing functions. Therefore the multifunctional inflator valve assembly has better sealing performance over the common sealing ring.
