Wherein:
(1), safety valve, (2), delivery valve, (3), super flow output automatic stop valve, (4) gas charging valve, (5), liquid level transmission indication mechanism, (6), inflate excessive volitional check valve, (7) are bleed valve manually, (8), valve body, (9), spool, (10), spring, (11) adjustment sleeve, (12), spool, (13), valve pocket, (14), handwheel, (15), jump ring, (16) seal ring, (17), spool, (18) spring, (19), valve pocket, (20), suction pipe, (21) valve seat, (22), spool, (23), spring, (24) joint, (25), set screw nut, (26) dust cover, (27) connecting tube (28), cursory, (29), cursory axle, (30), driving gear, (31), support, (32) transmission shaft, (33), rotating shaft, (34), magnet, (35), pointer, (36), magnet, (37), dial, (38), the table lid, (39), inductor, (40), valve pocket, (41), spool, (42), spring, (43), seal ring, (44), lock screw.
Below in conjunction with drawings and Examples the utility model is made comparisons and to explain:
Safety valve (1) is made up of spool (9), spring (10) and adjustment sleeve (11).And be installed on the valve body (8), its working principle is behind the pressure overrate in the air cylinder, spool (9) is just opened, and discharges air venting, thereby guarantees the safety of air cylinder.
Gas valve (2) is that spool (12) is installed in valve pocket (3), connects handwheel (14), and jump ring (15) seals with two seals circle (16).And be installed on the valve body (8), rotate handwheel (14), carry out opening or closing control.
Super flow output automatic stop valve (3) is that spool (17) is installed in valve pocket (19), connects spring (18) and suction pipe (20), and is installed on the valve body (8).Behind the liquefied petroleum gas (LPG) overrate of output, spool (17) is under liquefied petroleum gas (LPG) flows the thrust that is produced, and the elastic force above spring (18) is taken a seat spool (17) and closed automatically, thereby can in time control the leakage of liquefied petroleum gas (LPG).
Gas charging valve (4) is that spool (22) is installed in valve seat (21), connects spring (23), joint (24), and set screw nut (25) dust cover (26) and connecting tube (27), and be installed on the valve body (8).Aim at gas charging valve (4) when inflating when charge gun, enter gas cylinder after the liquefied petroleum gas (LPG) with certain pressure is backed down spool (22), stop to inflate back valve core (22) and under the effect of spring (23), close automatically.
Liquid level transmission indication mechanism (5) by cursory (28), connects cursory axle (29), driving gear (30), support (31), transmission shaft (32), rotating shaft (33), and at the last magnet (34) of installing of valve body (8), pointer (35), magnet (36), dial (37), table lid (38), liquid level remote transfer signal inductor (39).When liquid level change, cursory (28) drive rotating shaft (33) by driving gear (30) and transmission shaft (32) and rotate corresponding angle, the magnet (36) that bonds on the magnet (34) of rotating shaft front end bonding and the pointer forms the magnetic drives pair, under the effect of magnetic force, valve body (8) by nonmagnetic substance is sent to the liquid level signal in the air cylinder outside the air cylinder, to show its liquid level.Liquid level remote transfer signal inductor (39) is a Hall magnetic cell, it converts the variation of the magnetic line of force to the variation of electrical signal, the electrical signal that will amplify through amplifier is sent in the instrument in the operator cabin by cable again, and liquefied petroleum gas (LPG) in the air cylinder what show.
Inflating excessive volitional check valve (6), is that spool (41), spring (42), seal ring (43) are installed in valve pocket (40).And be installed on the valve body (8).Because the liquefied petroleum gas (LPG) air cylinder only allows to fill 80% ± 2% liquefied petroleum gas (LPG), so inflate excessive limiting valve by the control of liquid level transfer mechanism, liquid level does not reach when limiting the position during inflation, the axle of spool (41) withstands in the rotating shaft (33), spool can not be taken a seat, promptly can not close; When liquid level rises to the qualification position, rotating shaft (33) also turns to corresponding position under the drive of cursory (28) and transmission shaft (32), a hole is opened in rotating shaft (33) in this position, claim to limit the quantity of the hole, the axle of spool this moment (41) is just in time aimed at and is fallen in the hole of limiting the quantity of in the rotating shaft, spool (41) is taken a seat close inflation inlet, inflation stops automatically.
Manually bleed valve (7) is mounted in the needle value on the valve body (8).Behind the whole liquefied petroleum gas (LPG) air cylinder combination brake switch and proporting assembly and adjustment, be attached at bolt on the bottleneck flange of air cylinder, junction plane adds a seal ring, the liquid level signal transfer cable wire is inserted again.
