Description
Technical field
The utility model relates to a kind of parts that are applied on the tire, is specifically related to a kind of multi-functional automatic decompression explosion-proof valve inside that is fixed in the pneumatic tire valve nozzle.
Background technique
Existing tyre valve core has two kinds of structures, and a kind of is interior spring valve inside, and the core spring is contained in the core body; A kind of is outer spring valve inside, and core spring and spring abutment are contained in core print seat one side.Two kinds of each tool advantages of valve inside all are widely used.Outer spring valve inside has specific (special) requirements to valve nozzle, and interior spring valve inside can be with in the spring valve inside valve nozzle outside, in outer spring valve inside cannot be used in the spring valve inside valve nozzle.Tire after the inflation in use because extraneous temperature raises or long-play, can cause that tyre temperature raises, and the tire internal air pressure increases, and the surface of contact on tire and ground reduces, and causes tire aging in advance, the stopping distance lengthening, and effectively braking weakens.Existing tire valve cored structure only has gas opening and closing function, can not open decompression under the situation of safety value automatically and closes when air pressure surpasses, and when the tire internal air pressure surpasses the highest safety value, causes tyre explosion easily, thereby causes major traffic accidents.
Patent No. ZL200420074926.7 is the explosion-proof plunger of the schumacher first generation, has automatic decompression open function, but do not have the air inlet of unlatching function, belong to one-way valve, give the tire make-up gas as need, must unload plunger, the valve inside loading and unloading have very big danger, valve inside can equally be shot human body wounded to bullet under the pressurized gas effect.A lot of low pressure tyre are to give the tire make-up gas whenever and wherever possible by artificial pump, and the valve inside loading and unloading need professional tool, and are very inconvenient.Schumacher explosion-proof plunger of two generations has normal open and close and decompression open and close automatically, but three place's seals are arranged structurally, Duo place's seal than existing valve inside, sealing is relative, existing valve inside just has the tire pressure phenomenon that slowly descends in long-term the use, common spare tyre is put a period of time just not foot phenomenon of air pressure, and the structurally existing valve core structure gas seal of schumacher explosion-proof plunger of two generations is good.Existing each component of valve inside all differ very little in external form, structure, size and production technology in the whole world; Each component of explosion-proof plunger on external form, structure, size and production technology and existing valve inside very big difference is arranged because the particularity and the widely-used property of valve inside, using and popularization has significant limitation.
Patent No. ZL200320119891.X and ZL200420080301.X are two patents of the inventor, these two patent deficiencys are that because the particularity and the widely-used property of valve inside, valve inside must be contained in the valve nozzle, external means can not be too much, too heavy, can influence wheel balance.And these two patent integral parts outside, is subjected to extraneous bump easily and waits other factor affecting, and valve inside is damaged.Number of patent application 200820185244.1 also is my patent.This patent deficiency is: installing than existing valve inside in use has technical requirements, and user's operation is had any problem.And explosion prevention function and common normal function can not structurally need to be used with dust cap by regulating conversion mutually on function, and dust cap is not abandoned not installing because of not main effect quilt in actual use, causes product function not reach easily.
Anti-explosion air valve is to set an explosion-proof air pressure the highest at present, when surpassing setting explosion-proof pressure value, air pressure inside will open decompression explosion-proof automatically, the necessary supporting corresponding specifications and models anti-explosion air valve of different PNEUMATIC TIRES does not have versatility with existing valve inside in the use, causes the wasting of resources.
The model utility content
In order to solve the above-mentioned deficiency that existing anti-explosion air valve exists, the purpose of this utility model provides a kind of inner core spring valve inside and outer core spring valve inside of being fit to simultaneously, make it to have open and close and automatic open and close decompression explosion-proof, simultaneously by regulating the multi-functional automatic decompression explosion-proof valve inside that conversion realizes that general function and explosion prevention function are changed.
The technical solution of the utility model realizes in the following manner:
A kind of multi-functional automatic decompression explosion-proof valve inside, comprise king-rod, the core cap that is run through by king-rod successively, inner core spring, core body, sealing gasket, core print seat, relief spring that king-rod is resetted, its king-rod is respectively equipped with locating point on the king-rod from top to bottom, core print seat is upwards moved locating point on the core print seat of the spacing step cutting patterns that are 360 degree, to core print seat to moving down locating point under the spacing core print seat, relief spring locating point; The inner core spring is compressed on core body interior step and the king-rod between the locating point; Core print seat and king-rod Spielpassung, sealing gasket is positioned at core print seat, relief spring is compressed between core print seat and the relief spring locating point, locating point and sealing gasket sealing realize whole gas circuit sealing on the sealing of sealing gasket and core body, the core print seat, core print seat by relief spring one side shaft to have on the end face one with core print seat under the groove of locating point corresponding matching.
Locating point is the symmetrical step of 180 degree under the core print seat, is 180 degree symmetries with the groove of locating point corresponding matching under the core print seat.
Described sealing gasket and king-rod Spielpassung, its gap length are the 0-0.6 millimeter.
