PURPOSE: A tire pressure sensor valve is provided to prevent failure of a tire pressure sensor in case of changing a tire with a tire sensor dropped inside a tire by releasing a nut outside a rim and making a valve body part to be separated. CONSTITUTION: A tire pressure sensor valve comprises a sensor housing(110), a valve body(120), and a valve adaptor(130). The sensor housing has a mounting space for accepting the PCB substrate, and a coupling space for holding the PCB substrate. A head unit(122) of the valve body is inserted into the coupling space of the sensor housing to be fastened to the sensor housing. An opening/closing unit(140) is mounted to an air injection hole inside the valve body. At usual times, the opening/closing unit blocks the injection hole by the elastic force. When injecting air, the opening/closing is opened and air is drawn in. The threads are formed at one end of the valve adaptor in order to fasten the valve cap. The valve adaptor extends the length of the valve body and has an extension unit for operating the opening and closing unit inside. |
