Abstract
The utility model relates to a relief valve of a tire of a motorcycle, comprising a valve body, a valve cover, a protecting cover, an exhausting support, an air relief pressure apparatus and a pressure spring; the utility model is characterized in that an air exit hole is arranged on a middle part of the exhausting support in the valve body; an outer thread corresponding to the inner clasp on a bottom end of the valve body is arranged at a side of the exhausting support; a cushion is arranged on another side of the exhausting support; the air relief pressure apparatus is arranged in the valve body, in which a cylinder rod is arranged at the middle part of the air relief pressure apparatus; a releasing spring is sleeved outside the cylinder rod; an adjustable pressure screw is arranged on the releasing spring; an anti-slip slice and a fastening screw are arranged sequentially outside the adjustable pressure crew; a clamping column is arranged under the releasing spring; a cushion rubber is sleeved on a concave at an end of the cylinder rod; and a pointed end is inserted into the air exit hole on the middle part of the exhausting support; an air-bleed hole is arranged around the valve body; an inner edge is arranged on a top of the valve cover to retain the pressure spring; the protecting cover is arranged outside the inner edge; three supports provided with a hook and connected with the pressure spring are arranged in the protecting cover; the valve cover is connected with the valve body through an internal thread and an external thread. The relief valve has the advantages of simple and convenient installation, adjustable pressure, high safety coefficient, long service life and dustproof design, thereby being an effective apparatus for the explosion-proof of the tire of the motorcycle.
Description
Technical field: the utility model belongs to a kind of tire anti-explosion safety, specifically automobile tyre safety valve.
Background technology: at present, self-propelled vehicle is too fast or temperature is hot as the speed of a motor vehicle in the process of moving, and gas just easily expands and blows out in the tire, and solving the tire anti-explosion measure now mainly is to stop with driver's experiences to exit and inner tire quality.
Summary of the invention: the purpose of this utility model is, develops when gas reaches certain limit in a kind of wheel for motor vehicle fetus in fetus, and valve is outwards exhaust automatically just, carries out the automobile tyre safety valve of SELF CL during to normal barometric pressure again.Its technology contents is, the automobile tyre safety valve, by valve body, valve pocket, protecting cover, the exhaust support, the blow off pressure device, pressure spring constitutes, it is characterized in that, be provided with an exhaust hole in the valve body in the middle of the exhaust support, the exhaust support simultaneously be provided with the valve body bottom in the button corresponding outside thread line, another side is provided with rubber cushion, being provided with a centre in the valve body is piston rod, overcoat hold-off pressure spring, the hold-off pressure spring is provided with the adjustable pressure screw, the adjustable pressure screw is provided with anti-slide plate and holding screw outward successively, the hold-off pressure spring has the card post, the recess of piston rod one end is with cushion rubber and the piston rod tip is injected the blow off pressure device of the exhaust hole in the middle of the exhaust support, is provided with air bleed hole around the valve body; The interior edge of a retaining pressure spring is established on the valve pocket top, is provided with outside the interior edge to be provided with the support that three connection pressure spring bands collude in a protecting cover, the protecting cover, and valve pocket is connected by internal and external threads with valve body.Its principle of work, the air pressure that can bear according to automobile tyre, screw on the blow off pressure spring is transferred to the maximum pressure that tire can bear, then safety valve is screwed on the air tube of tire, when the air pressure in the tire is excessive, Pneumatic pipe cleaner is crossed air bleed hole and is pushed piston rod, and at this moment, piston rod retreats and leaves deflation hole over-pressure gas is discharged; After over-pressure gas was thoroughly discharged, pressure spring returned the piston masthead to the original position closed grate hole again.The utility model is compared its advanced part and is with prior art, the automobile tyre safety valve, have the characteristics of scientific structure, simple installation, adjustable in pressure, safety factor height, wear-resistant, dustproof, long service life, can't carry out self-bleeding weak point when big thereby overcome existing wheel for motor vehicle air pressure.
Description of drawings:
This figure is just cuing open structural representation for the utility model;
Wherein, in valve body 1, exhaust support 2, exhaust hole 3, piston rod 4, cushion rubber 5, hold-off pressure spring 6, air bleed hole 7, valve pocket 8, blow off pressure device 9, pressure spring 10, adjustable pressure screw 11, slipmat 12, the retaining pressure spring along 13, the band support 14, holding screw 15, the protecting cover 16 that collude.
The specific embodiment: the utility model is done description further again below in conjunction with accompanying drawing, in the valve body 1, in the exhaust support 2, be provided with an exhaust hole 3, exhaust support 2 one side be provided with valve body 1 bottom in the corresponding outside thread line of button, another side is provided with rubber cushion, being provided with a centre in the valve body 1 is piston rod 4, overcoat hold-off pressure spring 6, hold-off pressure spring 6 is provided with adjustable pressure screw 11, adjustable pressure screw 11 outer anti-slide plate 12 and the holding screws 15 of being equipped with successively, hold-off pressure spring 6 has the card post, the recess of piston rod 4 one ends is with cushion rubber 5, and piston rod 4 tips are injected the blow off pressure device 9 of the exhaust hole 3 in the middle of the exhaust support 2, be provided with air bleed hole 7 around the valve body 1; The interior along 13 of a retaining pressure spring 10 established on valve pocket 8 tops, and interior being provided with along 13 outside is provided with three and connects pressure springs 10 and be with the support 14 that colludes in a protecting cover 16, the protecting cover 16, and valve pocket 8 and valve body 1 are connected by internal and external threads.Below just constitute the utility model.
