Abstract
The utility model belongs to the technical field of exhaust valves, and relates to a quick exhaust valve. A valve body is installed in an outer shell in a sealed and sleeved mode. A valve seat is connected with the lower portion of the hollow valve body in a sealed and threaded mode. A plug is connected with the upper end of the hollow valve body in a sealed and threaded mode. A valve core is arranged on the valve seat. An ejector rod of the valve core stretches downwards into the valve seat. A spring A is arranged between the valve core and the plug. A tappet which can slide on the ejector rod and abut against the valve core is installed on the ejector rod of the valve core in a sleeved mode. A blind hole formed in the upper portion of the tappet is connected with the ejector rod in a supporting mode. The lower portion of a tappet body stretches out of the outer shell in a sealed mode. A spring B is arranged between the blind hole of the tappet and the valve core. Air inlet holes are formed in the upper portion of the outer shell and the upper portion of the valve body. Air returning ports communicated with an air storage chamber are formed in the middle of the outer shell and the middle of the valve body. Air outlet holes are formed in the lower portion of the outer shell and the lower portion of the valve body. When the tappet compresses the spring B and pushes the valve core to move upward so as to open the quick exhaust valve, the air returning ports are communicated with the lower surface of the valve core so that the valve core is quickly pushed to move upwards, and the air inlet holes are communicated with the air outlet holes through the valve core and the valve seat so as to exhaust air quickly. The quick exhaust valve has the advantages of being simple in structure, quick and reliable in air exhausting, and suitable for quick exhaust occasions.

The purpose of this utility model provides a kind of rapid escape valve.
The purpose of this utility model is achieved in that
A kind of rapid escape valve, stuffing box gland is equipped with valve body in the enclosure, the hollow valve body lower seal is bolted with valve seat, the upper end sealing is bolted with plug, valve seat is provided with push rod and stretches into the interior spool of valve seat downwards, be provided with spring A between spool and the plug, be set with the tappet that can on push rod, slide and withstand spool on the push rod of spool, the upper blind bore of tappet is accepted push rod, the body of rod sealing of bottom is stretched out outside the shell, be provided with spring B between the blind hole of tappet and the spool, the top of shell and valve body is provided with inlet hole, the middle part is provided with the return-air mouth that is communicated with gas storage chamber, the bottom is provided with the air outlet, tappet pressure spring B also pushes and moves when opening valve on the spool, the return-air mouth is communicated with to push on the spool rapidly with the lower surface of spool and moves, and inlet hole is communicated with quick exhaust with the air outlet by spool and valve seat.
The outer surface of upper of above-mentioned spool is provided with the flat gas-entered passageway that is communicated with the return-air mouth.
Be provided with seal ring between above-mentioned plug and the valve body, be provided with between the shell of described inlet hole upside and the valve body between seal ring, inlet hole and the return-air mouth shell and valve body between be provided with seal ring, be provided with seal ring between the lower end of shell and the tappet.
Above-mentioned sealing is spirally connected: described seal ring is to make with rubber material or silica gel material.
The utility model gives prominence to compared to existing technology and beneficial technical effects is:
1, the utility model is when tappet just backs down spool, and the gas in the air storing cavity can push on the spool rapidly and move, and to open the exhaust passage exhaust rapidly, adapts to the needs of quick exhaust.
2, of the present utility model simple in structure, the reliability height of work, long service life is adapted to rapid escape valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
A kind of rapid escape valve, at shell 9 inner seal sleeves valve body 1 is housed, hollow valve body 1 lower seal is bolted with valve seat 14, the upper end sealing is bolted with plug 19, valve seat 14 is provided with push rod 15 and stretches into spool 16 in the valve seat 14 downwards, be provided with spring A17 between spool 16 and the plug 19, be set with the tappet 10 that can on push rod 15, slide and withstand spool 16 on the push rod 15 of spool 16, the upper blind bore 11 of tappet 10 is accepted push rod 15, the body of rod sealing of bottom is stretched out outside the shell 9, be provided with spring B 13 between the blind hole 11 of tappet 10 and the spool 16, the top of shell 9 and valve body 1 is provided with inlet hole 3, the middle part is provided with the return-air mouth 7 that is communicated with gas storage chamber 6, the bottom is provided with air outlet 8, tappet 10 pressure spring B13 and pushing on the spool 16 move when opening valve, return-air mouth 7 is communicated with to push rapidly on the spool 16 with the lower surface of spool 16 and moves, and inlet hole 3 is communicated with quick exhaust with air outlet 8 by spool 16 and valve seat 14.
The outer surface of upper of above-mentioned spool 16 is provided with the flat gas-entered passageway 5 that is communicated with return-air mouth 7.
Above-mentioned sealing is spirally connected and is: be provided with seal ring 18 between described plug 19 and the valve body 1, be provided with between the shell 9 of described inlet hole 3 upsides and the valve body 1 between seal ring 2, inlet hole 3 and the return-air mouth 7 shell 9 and valve body 1 between be provided with seal ring 4, be provided with seal ring 12 between the lower end of shell 9 and the tappet 10.
Above-mentioned seal ring the 18,2,4, the 12nd is made with rubber material or silica gel material.
Working principle of the present utility model: external force upwards promotes tappet 10, and the bottom of pressure spring B13, spool 16 is subjected to the last thrust of spring B; The top of spool 16 is subjected to the following thrust of the atmospheric pressure and the spring A17 of gas storage chamber 6, because following thrust is greater than last thrust, spool 16 and valve seat 14 junctions seal closure, continue upwards to apply external force, on running into spool 16 and continue, the upper-end surface of tappet 10 moves, force spool 16 and valve seat 14 junctions to separate, seal and open.The air pressure on spool 16 tops is discharged through relief opening 8.Because atmospheric pressure disappearance and spring B 13 power move up spool 16 rapidly greater than spring A17 power.The flat gas-entered passageway 5 on the left side of spool 16 upper cylinder is gas supplementing openings, and during shown position, the gas of suction port 3 is inflated to gas storage chamber 6 by gas supplementing opening; Gas supplementing opening breaks away from shown position when moving on the spool 16, and the gas of suction port 3 can not be by gas supplementing opening to gas storage chamber 6 inflations.
