Abstract
The utility model discloses a non-repetitive filling cylinder valve. The non-repetitive filling cylinder valve comprises a valve rod (1), a valve body (2), a spring (3), a plug pin (4), and a valve element (5), wherein the valve rod (1) is arranged in the valve body (2) to be connected with the valve body (2) in a sealing mode, the valve element (5) is arranged at the top end of the valve rod (1), and a valve cavity in the valve body (2) is arranged at a position corresponding to a valve nozzle. The non-repetitive filling cylinder valve is characterized in that the spring (3) is arranged between the valve element (5) and the valve rod (1), and the spring (3) is fixed in a valve rod column cavity (9) through the plug pin (4) after compressed. The non-repetitive filling cylinder valve has the advantages that the situations that a repetitive filling person is prevented from prizing the valve element with a needle point or enables the valve element to break away from the valve seat in a reversing mode, a foreign object is cushioned between the valve element and the valve seat, the foreign object is removed after forced filling, and repetitive filling is carried out in the similar way are prevented, and filling is prevented after reassembly when the on-repetitive filling cylinder valve is detached.
Description
Technical field
The utility model relates to a kind of cylinder valves for non-refillable cylinder.
Background technique
The cylinder valves for non-refillable cylinder that existing market has generally comprises valve body, handle for valve stem and O RunddichtringO.Under normal state, can not in bottle, again fill fluid, but many users arranged under the ordering about of economic benefits, lever up spool or anastrophe makes spool disengaging valve seat with needle point, then between spool and valve seat, pave with foreign matter, after filling by force, remove again underbed, repeatedly fill use with this.
Summary of the invention
For the shortcoming of existing cylinder valve, the utility model provides a kind of good airproof performance, can effectively, reliably prevent the reusable cylinder valve of violation of non-refillable steel cylinder and disposable Bottle ﹠ Can.
To achieve these goals, the utility model institute Adopts measure is:
A kind of cylinder valves for non-refillable cylinder, comprise valve rod, valve body, spring, latch, spool, valve rod is installed in the valve body and is connected with valve seal, spool places valve stem tip, wherein the valve pocket in the valve body is located at the position of corresponding valve nozzle, be provided with spring between spool and the valve rod, be fixed in the valve rod post chamber by latch behind the spring-compressed.
A kind of cylinder valves for non-refillable cylinder comprises valve body, valve rod, latch, spring, spool, and valve rod is installed in the valve body and is connected with valve seal, spring-compressed is placed in the valve rod post chamber, fixed by latch, spool places valve stem tip, and wherein the valve pocket in the valve body is located at the position of corresponding valve nozzle.Before medium filled, with the valve interior wall close-fitting, valve rod was equipped with O-ring seals between the top.After filling medium by the utility model, remove fender bracket, screw handle, make the latch fracture, the spring elongation, spool is combined in the port of valve body connection nipple in elastic force effect lower seal, and steel cylinder is closed.When opening cylinder valve, handle rotates up movement, and the pressure-acting lower compression spring of spool medium in bottle is washed spool open, and a bottle interior medium is normally discharged outside the bottle by the valve body connection nipple.When stopping using, screw handle, steel cylinder is sealed again, with this repeatedly open, bolt down procedure.After medium release is complete, upwards screw handle, spool is under the elastic force effect, still be sealed in the port of valve body connection nipple, namely by the spacing port at the valve body connection nipple of spring, can't fill, even reinstall cylinder valve, because the latch fracture, spool still can be under the elastic force effect, by the spacing port at the valve body connection nipple of spring, can't carry out repeated charging, even reinstall cylinder valve, because latch fracture, spool still can under the elastic force effect, by the spacing port at the valve body connection nipple of spring, still can not carry out repeated charging.
The beneficial effect of cylinder valves for non-refillable cylinder described in the utility model: the person that can prevent the repeated charging levers up spool with needle point or anastrophe makes spool break away from valve seat, then between spool and valve seat, pave with foreign matter, repeated charging by force, especially the person that can prevent the repeated charging takes cylinder valve apart and again fills after re-assemblying, and simple in structure, durable, working life is longer.

Fig. 1, STRUCTURE DECOMPOSITION schematic representation of the present utility model.
Embodiment
As shown in Figure 1, valve rod (1) is contained in the valve body (2) and is tightly connected with valve body (2), be fixed in the valve rod post chamber (9) with latch (4) after spring (3) compression, spool (5) offsets with valve rod (1) top, the lower end of spool (5) is made bowl-shape, before medium filled, with valve body (2) inwall close-fitting, valve rod (1) was equipped with O-ring seals (8) between the top.After filling medium by the utility model, remove fender bracket (7), screw handle (6); make latch (4) fracture; spring (3) elongation, spool (5) is combined in the port of valve body connection nipple (10) in elastic force effect lower seal, and steel cylinder is closed.When opening cylinder valve, handle (6) rotates up movement, and spool (5) is pressure medium effect lower compression spring (3) in bottle, washes spool (5) open, and bottle interior medium is discharged outside the bottle by valve body connection nipple (10) is normal.When stopping using, screw handle (6), steel cylinder is sealed again, with this repeatedly open, bolt down procedure.After medium release is complete, upwards screw handle (6), spool (5) still is sealed in the port of valve body connection nipple (10) under the elastic force effect, namely spacing at the port in valve body connection nipple (10) by spring (3), can't carry out repeated charging, even reinstall cylinder valve, because latch (4) fracture, spool (5) still can be under the elastic force effect, by the spacing port in valve body connection nipple (10) of spring (3), still can not carry out repeated charging.
Claims (1)
1. cylinder valves for non-refillable cylinder, comprise valve rod (1), valve body (2), spring (3), latch (4), spool (5), valve rod (1) is installed in the valve body (2) and is tightly connected with valve body (2), spool (5) places valve rod (1) top, wherein the valve pocket in the valve body (2) is located at the position of corresponding valve nozzle, main feature is: be provided with spring (3) between spool (5) and the valve rod (1), be fixed in the valve rod post chamber (9) by latch (4) after spring (3) compression.
