Abstract
The utility model discloses a kind of valve for liquified petroleum gas cylinder, include valve body, the one-way valve stoping liquefied petroleum gas (LPG) to flow out when steel cylinder is inverted is installed in that section of passage of next-door neighbour's steel cylinder of valve body, described one-way valve includes valve ball and is arranged in passage the retainer keeping valve ball movable between check-valve port, and valve channel is formed with the groove clamping retainer on the perisporium of retainer lower end.When user attempts the raffinate of toppling in steel cylinder or illegally fills, they need steel cylinder to turn around, and when steel cylinder is reversed simply by removing the current, valve ball is moved to the check-valve port of valve channel under the effect of gravity and fluid, check-valve port is blocked, thus disconnect cylinder valve passage, illegal operation is become infeasible.
Description
Technical field
The utility model relates to valve for liquified petroleum gas cylinder technical field.
Background technique
In the user using bottled gas, certain user can carry out illegal dumping raffinate, more seriously certain user can illegally fill, the gas cylinder being about to fill from regular liquefied gas station pours in down a chimney liquid gas to make profit to empty bottle, these behaviors not only destroy trade management order, also to the potential safety hazard that user brings.Why there is above-mentioned situation, is because existing liquefied petroleum gas cylinder valve lacks the function that prevents from toppling over liquefied petroleum gas (LPG).
Model utility content
The technical problems to be solved in the utility model is to provide a kind of cylinder valve preventing from toppling over liquefied petroleum gas (LPG).
For solving the problems of the technologies described above adopted technological scheme: a kind of valve for liquified petroleum gas cylinder, include valve body, the one-way valve stoping liquefied petroleum gas (LPG) to flow out when steel cylinder is inverted is installed in that section of passage of next-door neighbour's steel cylinder of valve body, it is characterized in that: described one-way valve includes valve ball and is arranged in passage the retainer keeping valve ball movable between check-valve port, and valve channel is formed with the groove clamping retainer on the perisporium of retainer lower end.
On the basis of the above, the lower end of described retainer is formed with the spike of outer the sticked into groove tiltedly stretched.Or also comprise and may be stuck in groove with the snap ring of gear in retainer lower end.
Adopt the beneficial effect that brings of the utility model: when user attempts the raffinate of toppling in steel cylinder or illegally fills, they need steel cylinder to turn around, and when steel cylinder is reversed simply by removing the current, valve ball is moved to the check-valve port of valve channel under the effect of gravity and fluid, check-valve port is blocked, thus disconnect cylinder valve passage, illegal operation is become infeasible.

Embodiment
Embodiment one
As shown in Figure 1-2, a kind of valve for liquified petroleum gas cylinder, include valve body 1, the one-way valve stoping liquefied petroleum gas (LPG) to flow out is installed in that section of passage 11 of next-door neighbour's steel cylinder of valve body 1, is usually formed with the check-valve port 11.1 can blocked up by unidirectional jam pot cover in the upper end of passage 11 when steel cylinder is inverted.In the present embodiment, described one-way valve includes valve ball 2 and is arranged in passage 11 retainer 3 keeping valve ball 2 movable between check-valve port 11.1, and valve channel 11 is formed with the groove 11.2 clamping retainer 3 on the perisporium of retainer 3 lower end.Concrete, retainer 3 has the collar 31 being set with valve ball 2, is formed with some stiffening ribs 32 around the collar 31, is flow channel 33 between stiffening rib 32 and stiffening rib.When steel cylinder is inverted, valve ball 2 is moved to the check-valve port 11.1 of valve channel 11 under the effect of gravity and fluid, check-valve port is blocked, thus disconnects cylinder valve passage, illegal operation is become infeasible.And when normally using, the effect that valve ball 2 is subject to gravity falls in the collar 31 of retainer 3, valve ball 2 does not have shutoff check-valve port 11.1, and the passage 11 of valve body 1 keeps unimpeded.For ease of the assembling of retainer 3 and valve ball 2, the lower end of retainer 3 is formed with the spike 34 of outer the sticked into groove tiltedly stretched 11.2.During assembling, by force the passway 11.3 of retainer 3 from passage 11 lower end can be pressed into, strut until the spike 34 of retainer 3 is slipped into the interior also elasticity of groove 11.2, make retainer 3 block groove 11.2, complete clamping of retainer 3.Certainly, retainer 3 also can adopt the clamping structure of other routine to be installed in passage 11.
Embodiment two
With embodiment one unlike, as shown in Figure 3-4, retainer 3 does not form spike 34, but arranges snap ring 4 in the lower end of retainer 3, and snap ring 4 may be stuck in groove 11.2, and retainer 3 is kept off in passage 11.Snap ring 4 can adopt trip ring, thus makes assembling more convenient.
Claims (3)
1. a valve for liquified petroleum gas cylinder, include valve body, the one-way valve stoping liquefied petroleum gas (LPG) to flow out when steel cylinder is inverted is installed in that section of passage of next-door neighbour's steel cylinder of valve body, it is characterized in that: described one-way valve includes valve ball and is arranged in passage the retainer keeping valve ball movable between check-valve port, and valve channel is formed with the groove clamping retainer on the perisporium of retainer lower end.
2. valve for liquified petroleum gas cylinder according to claim 1, is characterized in that: the lower end of described retainer is formed with the spike of outer the sticked into groove tiltedly stretched.
3. valve for liquified petroleum gas cylinder according to claim 1, is characterized in that: also comprise and may be stuck in groove with the snap ring of gear in retainer lower end.
