Abstract
The utility model relates to a tyre air valve, which comprises a valve seat (10), wherein, the center of which is provided with a valve chamber (9), a valve core (4) which is inserted into the valve chamber (9), wherein, the center of the valve core is provided with a valve core inner cavity (3), and a valve core press cap (6) which presses the valve core (4), and inner wall of the press cap is connected with threads which are arranged on an outer wall of the valve seat (10). The valve core (4) which is arranged in an inner cavity part of the valve chamber (9) is sheathed with a rubber tube (7), the rubber rube (7) covers an air hole (8) for communicating the valve core inner cavity (3) and the valve chamber (9). The utility model is characterized in that the upper port part of the valve core inner cavity (3) is provided with a sealed body (2) for clogging the valve core inner cavity (3); a top pressure cap (1) is tightly pressed on the sealed body (2). The sealed body can clog the valve core inner cavity which is used for an air leakage passage, and a tyre need not inflate in a long period.
Description
The utility model relates to a kind of valve of tire.
In the prior art, Tyre air valve comprise central authorities have the valve seat of valve pocket, be inserted in central authorities in the described valve pocket have valve core cavity spool, be pressed on the described spool and spool pressure cap that its inwall is connected with the outer wall thread of described valve seat, the valve core upper sleeve that is positioned at valve pocket inner chamber part has rubber tube, this rubber tube has covered the pore that is used to be communicated with valve core cavity and valve pocket, rely on rubber tube to seal mutually between the outer wall of described spool and the inwall of described valve seat, the part outer wall that exposes to valve seat of described spool is provided with screw thread; When giving inflation of tire, air-flow enters valve pocket through air passing hole by rubber tube again through valve core cavity.When tire normally used, the gas in the tire can be revealed away through valve core cavity more very lentamente through air passing hole.
The purpose of this utility model is to provide a kind of can reduce the Tyre air valve that air valve loses heart.
The technical solution of the utility model is: a kind of Tyre air valve, comprise central authorities have the valve seat of valve pocket, be inserted in central authorities in the described valve pocket have valve core cavity spool, be pressed on the described spool and spool pressure cap that its inwall is connected with the outer wall thread of described valve seat, the valve core upper sleeve that is positioned at valve pocket inner chamber part has rubber tube, this rubber tube has covered the pore that is used to be communicated with valve core cavity and valve pocket, rely on rubber tube to seal mutually between the outer wall of described spool and the inwall of described valve seat, the part outer wall that exposes to valve seat of described spool is provided with screw thread; The upper oral part of described valve core cavity is provided with the seal that is used to stop up valve core cavity, has compressed the roof pressure cap on the sealing body, and described roof pressure cap is threaded mutually with described spool.
The utility model compared with prior art has following advantage:
Because the upper oral part at valve core cavity is plugged with seal, push down through the roof pressure cap again, therefore can block this disappointing passage of valve core cavity, can make that tire does not need to inflate in the more permanent time, and air valve has also only increased component seldom.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is structure master's sectional view of embodiment one of the present utility model;
