Abstract
A liquefied oil cylinder valve with an inflatable protection device comprises a valve body. The valve body is provided with an air inlet and an upper valve chamber; a middle valve chamber is arranged under the upper valve body, a lower valve chamber is arranged under the middle valve body, and an air port is formed in the side wall of the lower valve body. A valve stem is arranged in the upper valve chamber, and a sealing gasket is arranged at the lower end of the valve stem, and can be sealed on an upper neck opening between the upper valve chamber and the middle valve chamber. A slide bar penetrates the lower valve chamber from the middle valve chamber, an end socket is arranged at the upper end of the slider bar, and when the slider bar drops, the end socket can be plugged in a lower neck opening between the middle valve chamber and the lower valve chamber. A connecting bar is hinged to the lower end of the lower valve chamber, a floating body is arranged on the connecting bar, and when the floating body is free of buoyancy force, the connecting bar pushes the lower end of the slider bar upwards so that the end socket of the slide bar is not plugged in the lower neck opening; when the floating body floats upwards under the action of the buoyancy force, and the connecting bar rotates without pushing the slider bar, the slider bar drops, and the end socket of the slide bar is plugged in the lower net opening. By the liquefied oil cylinder valve, a cylinder can be known whether to be fully filled or not, so that excessive air inflation can be avoided.
Description
Technical field
The utility model relates to a kind of liquefied petroleum gas cylinder valve.
Background technique
With the liquefied petroleum gas cylinder valve of inflatable protective device for giving the occasion of liquefied petroleum gas (LPG) pneumatic inflation.When giving pneumatic inflation, preferably can know when steel cylinder is full of, so just can not produce the situation of hyperinflation.Yet existing liquefied petroleum gas (LPG) inflation operation does not possess this function, can only be rule of thumb or pressure change to judge whether steel cylinder is full of; Or by the time filled not air inlet and just stop inflation, and hyperinflation now, or the pressure range that pressure exceeds regulation causes overvoltage, and for user, using has certain potential safety hazard, also causes a warm and sunny energy waste simultaneously.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing liquefied petroleum gas (LPG) inflation cylinder valve, the utility model provides a kind of liquefied petroleum gas cylinder valve with inflatable protective device that judges whether steel cylinder is full of.
The technical scheme in the invention for solving the technical problem is: a kind of liquefied petroleum gas cylinder valve with inflatable protective device, comprise valve body, described valve body have suction port and with the uuper valve chamber of described suction port UNICOM, described suction port is vertical with described uuper valve chamber;
The middle valve pocket of the below Wei Yugai uuper valve chamber UNICOM of described uuper valve chamber, the lower valve chamber of the below Wei Yugaizhong valve pocket UNICOM of described middle valve pocket, offers ventilating hole on the sidewall of described lower valve chamber;
In described uuper valve chamber, be provided with valve rod, the lower end of described valve rod is provided with sealing gasket, between described uuper valve chamber and middle valve pocket, has upper eck, and described sealing gasket is salable on described upper eck;
Between described middle valve pocket and lower valve chamber, have lower eck, slide bar valve pocket from described penetrates in described lower valve chamber, and the upper end of described slide bar has end socket, the lower eck of the end socket described in when described slide bar falls described in can shutoff;
One side of the lower end of described lower valve chamber has one-sided extension part, on described one-sided extension part, be hinged with a connecting rod, described connecting rod is provided with buoyancy aid, thereby the connecting rod described in when described buoyancy aid is not subject to buoyancy is by the lower eck described in the not shutoff of end socket on top slide bar on the lower end of described slide bar; Thereby described buoyancy aid is subject to no longer withstanding described slide bar slide bar after connecting rod described in buoyancy when floating rotates to fall, the lower eck described in the end socket shutoff on slide bar.
Further, described valve rod is located in described uuper valve chamber.
Further, on described valve rod, be connected with handwheel.
Further, be also provided with a seal boss in the lower valve chamber of the below of described lower eck, described slide bar is provided with the sealing bulge loop coordinating with sealing boss.
The utility model in use, connects steel cylinder by the bottom of valve body, makes buoyancy aid be positioned at steel cylinder.Then the valve rod that rises makes the sealing gasket of valve rod lower end no longer seal eck.Then by suction port air inlet, thus gas from suction port through uuper valve chamber, valve pocket, lower valve chamber and ventilating hole be filled in steel cylinder.The liquid level of the liquefied petroleum gas (LPG) in steel cylinder constantly rises, when liquid level rises to certain level, buoyancy aid is floated by the effect of buoyancy, thereby drivening rod rotates, thereby no longer withstand described slide bar slide bar after connecting rod rotates, fall, the lower eck described in the end socket shutoff on slide bar, filling channel is blocked, cannot be filled with liquefied petroleum gas (LPG), charge operation personnel know that steel cylinder is full of again.
The beneficial effects of the utility model are: in gas replenishment process, can learn whether steel cylinder is full of, thereby prevent the generation of hyperinflation phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model under inflated condition.
Fig. 2 is steel cylinder structural representation of the present utility model while being full of.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of liquefied petroleum gas (LPG) gas charging valve, comprises valve body 1, described valve body 1 have suction port 2 and with the uuper valve chamber 3 of described suction port 2 UNICOMs, described suction port 2 is vertical with described uuper valve chamber 3.
The below of described uuper valve chamber 3 is the middle valve pocket 4 with these uuper valve chamber 3 UNICOMs, the below of described middle valve pocket 4 be with this in the lower valve chamber 5 of valve pocket 4 UNICOMs, on the sidewall of described lower valve chamber 5, offer ventilating hole 6.
In described uuper valve chamber 3, be provided with valve rod 7, the lower end of described valve rod 7 is provided with sealing gasket 8, has upper eck 9 between described uuper valve chamber 3 and middle valve pocket 4, and described sealing gasket 8 is salable on described upper eck 9.In the present embodiment, described valve rod 7 is located in described uuper valve chamber 3, on described valve rod 7, is connected with handwheel 10.Rotate handwheel 10 operable valve bar 7 liftings.
Between described middle valve pocket 4 and lower valve chamber 5, have lower eck 11, one slide bars 12 valve pocket 4 from described and penetrate in described lower valve chamber 5, described slide bar 12 upper end has end socket 13, the lower eck 11 of the end socket 13 described in when described slide bar 12 falls described in can shutoff.
