Abstract
A safety valve of a run-flat tire comprises a safety valve body. A valve spool moving chamber is arranged in the safety valve body, a valve spool is arranged in the valve spool moving chamber, one side of the valve spool moving chamber is communicated with a tire connector, the other side of the valve spool moving chamber is communicated with a booster cavity connector, the tire connector is communicated with the booster cavity connector through a connecting tube, and the valve spool moving chamber is communicated with outside air through an air connector. The safety valve is simple and compact in structure, small in size, light in weight, convenient in installation, reliable in operation, low in manufacturing cost, wide in applicable range and easy in popularization.
Description
Technical field
The present invention relates to a kind of tire safety valve, especially relate to a kind of trouble-proof tire safety valve.
Background technique
At present, the tire major part of using on the traffic tool is a pneumatic tire.In the vehicle driving process, the pressure in the tire can fluctuations under various situation.Cross when low or too high when tyre inner pressure, if security incident possibly take place untimely adopting an effective measure, Safety performance is lower.
Occurred multiple tire safety valve in the existing technology, but needed mostly could realize that structure was complicated, and be difficult to promote by spring assembly.A kind of pneumatic tire safety valve is disclosed like Chinese patent 201020584787.8; Valve body is made up of outer cap, rubber bowl, pressure house, adjustment screw, spring seat, Returnning spring, valve cap, is embedded with the rubber bowl in this outer cap, the upper end-hole socket of itself and pressure house; Be provided with two dividing plates in this pressure house; The adjustment screw wherein is housed on the upper clapboard, is distributed with air outlet hole on the dividing plate plate face, its lower clapboard middle part is provided with suction port; Be provided with valve cap and spring seat between these two dividing plates, in this valve cap and the spring seat Returnning spring be housed; Be set with valve inside in the mouth, on this valve inside plunger be housed, be top-loaded with the valve spring between plunger and the valve inside, its afterbody is provided with plate-like gas shutoff lid, and plunger and thimble apical grafting are equipped with Returnning spring between this thimble and lower clapboard, and structure is very complicated.
Summary of the invention
In order to overcome the above-mentioned defective that existing technology exists, it is a kind of simple in structure that the present invention provides, the trouble-proof tire safety valve that Safety performance is good.
Technological scheme of the present invention is: it comprises the safety valve valve body; Be provided with the spool recreation room in the said valve body; Be provided with spool in the spool recreation room, spool recreation room one side is communicated with the tire connection mouth, and spool recreation room opposite side is communicated with the booster cavity connection mouth; The tire connection mouth is communicated with the booster cavity connection mouth through connecting tube, and the spool recreation room communicates with ambient atmosphere through the atmosphere connection mouth.
Further, said spool can be " worker " font spool.
During use, the tire connection mouth of tire through valve connecting tube and safety valve coupled together two other interface of safety valve; Be booster cavity connection mouth and atmosphere connection mouth, connect the booster cavity and the ambient atmosphere of supercharging equipment respectively, the present invention utilizes pressure official post spool move left and right; Through sealing and being communicated with different interfaces, can under high pressure carry out release to tire, under low pressure tire is carried out plenum; There is not hysteresis, is swift in response, make the tire internal pressure keep stable; Tire is played effective protective action, and explosion-proof performance is good.
The present invention is simple in structure, compact, and volume is little, and is in light weight, easy for installation, reliable operation, and low cost of manufacture, applied widely, be easy to promote.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
With reference to Fig. 1, present embodiment comprises safety valve valve body 1, is provided with spool recreation room 7 in the valve body 1; Be provided with spool 3 in the spool recreation room 7; Spool recreation room 7 one sides are communicated with tire connection mouth 4, and spool recreation room 7 opposite sides are communicated with booster cavity connection mouth 5, and tire connection mouth 4 is communicated with booster cavity connection mouth 5 through connecting tube 2; Spool recreation room 7 communicates with ambient atmosphere through atmosphere connection mouth 6, and spool 3 is " worker " font spool.
During work, tire is connected with the tire connection mouth 4 of safety valve through the valve connecting tube, booster cavity connection mouth 5 and atmosphere connection mouth are connected the booster cavity and the ambient atmosphere of supercharging equipment respectively.When tyre inner pressure too high and during greater than booster cavity pressure; To promote spool 3 from the suction pressure of tire connection mouth and move, with the sealing of booster cavity connection mouth, at this moment toward booster cavity connection mouth 5 one ends; Tire connection mouth 4 communicates with atmosphere connection mouth 6, thereby reaches the purpose that realizes release.When tyre inner pressure is crossed low and during less than booster cavity pressure; Pressure official post spool 3 is toward moving left; At this moment, tire connection mouth 4 is communicated with booster cavity connection mouth 5 through connecting tube 2, and atmosphere connection mouth 6 is sealed; The high pressure air of coming out from the booster cavity of supercharging equipment gets into tires through connecting tube 2, thereby reaches the purpose that realizes supercharging.
Claims (2)
1. a trouble-proof tire safety valve comprises the safety valve valve body, it is characterized in that; Be provided with the spool recreation room in the safety valve valve body; Be provided with spool in the spool recreation room, spool recreation room one side is communicated with the tire connection mouth, and spool recreation room opposite side is communicated with the booster cavity connection mouth; The tire connection mouth is communicated with the booster cavity connection mouth through connecting tube, and the spool recreation room communicates with ambient atmosphere through the atmosphere connection mouth.
2. trouble-proof tire safety valve according to claim 1 is characterized in that, said spool is " worker " font spool.
