Abstract
This utility model relates to a kind of tyre safety valve being widely used in automobile, engineering truck, it include valve bottom is externally provided with the valve cylinder of interface that connects with tire aerating valve nozzle, valve port one end is placed in valve cylinder air pressure adjustment handle, open communicate with tire aerating valve nozzle at the bottom of valve tire gas outlet, tire valve thimble, the spring being positioned between the piston bottom valve cylinder, piston and air pressure adjustment handle in the outer interface connected with tire aerating valve nozzle at the bottom of valve, open in the air vent of valve cylinder periphery.Its feature is the automatic deflation when ambient temperature raises or uses overlong time tire internal gas pressure to exceed safety value, it is to avoid blows out, thus ensures the safe handling of tire.
Description
(1) technical field
This utility model relates to a kind of safety device, particularly to a kind of tyre safety valve.
(2) background technology
Having a great deal of in vehicle accident is all because wheel is blown out caused, its reason be wheel inflation rear wheel internal gas pressure with
Ambient temperature uses the time to become positive correlation, and in summer, temperature difference per day is big, and during vehicle long-play, in tire, temperature raises
And pressure increases, cause blowing out, and existing wheel tyre does not all design the safety device solving this problem.
(3) utility model content
The safety of automatic deflation decompression when the purpose of this utility model is to provide a kind of tire internal gas pressure to exceed safety value
Device tyre safety valve.
The scheme realizing this utility model technical purpose is: it includes that valve bottom is externally provided with and connects with tire aerating valve nozzle
The valve cylinder of interface, valve port one end be placed in valve cylinder air pressure adjustment handle, open and communicate with tire aerating valve nozzle at the bottom of valve
Tire valve thimble in the outer interface connected with tire aerating valve nozzle at the bottom of tire gas outlet, valve, it is positioned at the work bottom valve cylinder
Spring between plug, piston and air pressure adjustment handle, open in the air vent of valve cylinder periphery.
Preferably scheme is:
Valve cylinder is nested by thread connection with air pressure adjustment handle.
The interface that valve cylinder connects with tire aerating valve nozzle is hickey, and interface is integrated with valve cylinder.
After tire punches gas, screw socket at the bottom of this utility model valve is threaded onto on tire valve mouth, screws, tire valve thimble top
Opening tire valve, tire air chamber connects with relief valve valve cylinder, and when tire internal gas pressure is higher than safety value, tire internal gas pressure promotes lives
Plug motion, tire air chamber connects outside aerofluxus with the external world, when tire internal gas pressure is reduced to safety value, under the action of the spring,
Piston reverses direction is moved, and is closed by air valve, thus ensures that the normal of tire uses and safety.
(4) accompanying drawing explanation
Fig. 1 is this utility model front sectional view.
(5) detailed description of the invention
It is described further below in conjunction with the accompanying drawings, but is not limited only to this.
As it can be seen, it includes that valve bottom is externally provided with the valve cylinder 2 of hickey, the valve port one connected with tire aerating valve nozzle
Air pressure adjustment handle 1 that end is placed in valve cylinder 2, open communicate with tire aerating valve nozzle at the bottom of valve tire gas outlet 6, at the bottom of valve outside
Tire valve thimble 7 in the interface connected with tire aerating valve nozzle, it is positioned at the piston 5 bottom valve cylinder 2, piston 5 and air pressure
Regulate the spring 3 between handle 1, drive the air vent 4 in valve cylinder periphery.
Claims (3)
1. a tyre safety valve, it is characterised in that: it includes that valve bottom is externally provided with the interface that connects with tire aerating valve nozzle
