Automatic alarming type air valve and outomobile tyre containing said air valve

Abstract

A gas valve with an automatic alarm consists of a valve tube and a valve inside, which has a piston structure to seal or to discharge according to different pressure. A whistler is automatically actuated by the gas flow when the piston structure fails to seal, so that a driver can know the status of tire pressure to prevent from accidents occurred.

Description

technical field

[0001] The invention relates to a valve component of a gas inflation port in a pneumatic device and an automobile tire, in particular to an automatic alarm valve and an automobile tire containing the valve, and the automatic alarm valve on the automobile tire can be used in the car tire When the air pressure is insufficient, a sharp cry is generated to automatically warn the driver. Background technique

[0002] The vehicle should maintain sufficient tire pressure from beginning to end during driving. Only in this way can it be beneficial to ensure safe driving, especially in today's developed road network and many expressways, so vehicles are extremely common, safe driving is particularly important. But, how the driver finds the situation of insufficient tire pressure at any time when the vehicle is running, there has not been a good solution. In the prior art, although some technical solutions have been disclosed, such as tire deflation alarm, low pressure...

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 As shown, the automatic alarm valve of the present invention includes valve body 1 and the valve core in the tube body 1, the valve core adopts a piston structure that is sealed or deflated by pressure difference, and the outlet end of the deflated air flow is connected with Whistle 10, and the intake end of the whistle 10 communicates with the outlet end of the deflated airflow. The whistle body 9 of the whistle 10 is threadedly connected with the valve pipe body 1 . Of course, it is also possible to fix it in other ways, such as snap-in structure. The piston structure includes a sequentially connected piston 5, piston rod 12 and chute cross bar 8, a spring 7 is arranged on the end of the piston rod 12 close to the piston 5, and the spring 7, piston rod 12 and chute cross bar 8 are adapted in sections The movement of...
