Abstract
Provided is a rapid inlet and exhaust valve structure, and the structure is characterized in that an inlet valve cover and a valve core are arranged and at end openings of a right-left straight-through hole of a valve body, an inner cone is provided in the inlet valve core, a rubber piston is provided in a middle through hole of the valve body located between the inlet valve cover and the valve core, and a spring is arranged in the middle through hole of the valve body located between the rubber piston and the inlet valve cover. The bottom surface, which is opposite to the valve core, of the rubber piston, is conical, the conicity of the rubber piston is the same as that of an inner cone hole on the valve core, a bowl-shaped resilient edge opening is provided on an excircle of the rubber piston, an air outlet and an air inlet are just sealed by the resilient edge opening in a free state, and meanwhile, an end opening of the valve core is sealed by the conical surface of the rubber piston. The rapid inlet and exhaust valve structure is advantaged by simple structure and reliable work.
Description
Technical field
The present invention relates to a kind of pneumatic element, be specifically related to the structure of quick air intake-exhaust valve, belong to the pneumatic element technical field.
Background technique
It is the pneumatic clutch of power source that quick air intake-exhaust valve generally is used for pressurized air, its effect is to be connected with the cylinder of clutch brake, and feed pressurized air by quick air intake-exhaust valve to clutch brake, and in the process of clutch reset, rapidly the gas in the clutch brake cylinder is discharged, being conducive to fast braking, and equipment is safe and reliable.
At present; existing quick air intake-exhaust valve in the course of the work; leak gas through regular meeting; the atmospheric pressure that feeds in the cylinder is not enough; the not smooth phenomenon of exhaust takes place fast; this mainly is because the piston of existing rapid escape valve is the inside that freely is arranged on valve body; the piston contact with port exhaust plug is that mode with plane contact contacts; in case in the pressurized air or the external pollution thing enter the inside of valve body; just might cause the port bad connection of piston blocked portion or piston and exhaust plug to cause pressurized air to leak; thereby cause the pressurized air effective pressure deficiency that enters in the cylinder; and cause equipment thus can't proper functioning, and cause serious security incident thus.
Summary of the invention
The objective of the invention is to: at the existing existing above-mentioned defective of quick gas outlet valve, the invention provides a kind of structure of novel fast air intake-exhaust valve, overcome the existing existing above-mentioned defective of air intake-exhaust valve that hastens soon.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is:
A kind of structure of quick air intake-exhaust valve, it is characterized in that: the port at the two ends, the left and right sides of valve body clear opening installs and fixes air inlet valve gap and spool respectively, the inner end inside of air inlet spool is shaped on female cone, be provided with rubber piston in the valve body intermediate throughholes between air inlet valve gap and spool, be provided with spring in the valve body intermediate throughholes between rubber piston and air inlet valve gap, the bottom surface of the relative end with spool of rubber piston is coniform, its tapering is identical with female cone on the spool, cylindrical at rubber piston is shaped on a bowl type elastic edge, under free state, the bowl type elastic edge of rubber piston is just with air outlet and suction port sealing, simultaneously, the conical surface of rubber piston is with the port female cone sealing of spool.
Beneficial effect: the present invention is because after adopting said method, the position that can be spool is accurate, can not be subjected to the influence of extraneous foreign matter, thereby the port bad connection that causes piston blocked portion or piston and exhaust plug causes pressurized air to leak, thereby cause the pressurized air effective pressure deficiency that enters in the cylinder, and cause equipment thus can't proper functioning, and cause serious security incident thus.
Description of drawings
Accompanying drawing is structural principle plan view of the present invention;
Shown in the figure: 1, air inlet valve gap; 2, valve body; 3, spring; 4, rubber piston; 5, spool; 6, female cone; 7, air outlet; 8, bowl type elastic edge; 9, suction port; 10, relief opening.
Embodiment
The clear opening that communicates about in the middle of valve body (2), being shaped on, waist location at valve body (2) is shaped on the air outlet (7) that is connected with valve body (2) interior bone, this air outlet (7) communicates with the inside of cylinder or other operation mechanism, port at the two ends, the left and right sides of valve body (2) clear opening installs and fixes air inlet valve gap (1) and spool (5) respectively, air inlet valve gap (1) is shaped on suction port (9) and relief opening (10) respectively with the centre of spool (5), in concrete pneumatic system, suction port (9) communicates with source of compressed air, relief opening (10) directly communicates with ambient atmosphere, air outlet (7) links to each other with cylinder or other pneumatic element inside, the inner of described air inlet spool (5) is shaped on female cone (6), be provided with rubber piston (4) in valve body (2) intermediate throughholes between air inlet valve gap (1) and spool (5), be provided with spring (3) in valve body (2) intermediate throughholes between rubber piston (4) and air inlet valve gap (1), rubber piston (4) is coniform with the bottom surface of the relative end of spool (5), its tapering is identical with female cone (6) on the spool (5), cylindrical at rubber piston (4) is shaped on bowl-shape bowl type elastic edge (8), under free state, the bowl type elastic edge of rubber piston (4) is just with air outlet (7) and suction port (9) sealing, simultaneously, the conical surface of rubber piston (4) is with port female cone (6) sealing of spool (5).
Working principle of the present invention is: in concrete pneumatic system, suction port (9) communicates with source of compressed air, relief opening (10) directly communicates with ambient atmosphere, air outlet (7) links to each other with cylinder or other pneumatic element inside, when pressurized air feeds from suction port (9), because the acting in conjunction of compressed-air actuated pressure and spring (3), rubber piston (4) will feed the relief opening (10) of atmosphere and shut, and because the bowl type elastic edge (8) on the cylindrical of rubber piston (4) is to produce distortion in the pressure effect, so, (7) link to each other with cylinder or other pneumatic element inside pressurized air from the air outlet, enter working state, and when the pressurized air of suction port (9) end is removed, because air outlet (7) links to each other with cylinder or other pneumatic element inside, have higher pressure, so, just force rubber piston (4) to retreat, so open female cone (6), air is entered in the atmosphere rapidly.
