Abstract

The utility model relates to a liquified gas pressurizing valve, which comprises a spherical sealing ring, a hand wheel, etc. The utility model is characterized in that the hand wheel is provided with a hollow screw bolt and a valve seat passes through the hollow screw bolt. One end of the valve seat is connected with a one-way air inlet valve and the other end is connected with a valve core. The other end of the valve core is sheathed with the spherical sealing ring. In cold seasons, when combustible liquid in a steel cylinder can not be gasified completely, a pressure reducing valve is detached, a pressurizing valve is installed. Air is delivered into the steel cylinder by an inflating pump or an air pump, the combustible fluid in the steel cylinder can be gasified completely when the air pressure in the steel cylinder reaches 1KG. The utility model has the advantages of simple structure, compactness, easy use, obvious effect, low cost, etc.

Description

Liquified gas pressurizing valve

The utility model relates to a kind of valve, and especially a kind of can making by extraneous air supply system pressed the valve that increases in the gas cylinder.

In background technique, general liquid gas gas cylinder has only common valve, adds reduction valve again, like this, in cold season or area, when often Yin Wendu is low, liquid gas liquid is difficult to be gasified totally, use low because of temperature to very likely the time, pressure is little, can not gasify again, has caused the liquid gas residual liquid, can not make full use of the combustion body in the bottle, so often adopt the outer method of heating that bottle internal combustion liquid is gasified again, like this, not only time-consuming, trouble but also dangerous.

This practical purpose provide a kind of can be in gas cylinder for air, the device that bottle internal air pressure is raise reaches because of air pressure raises the interior liquid of bottle is gasified, and reaches the purpose that makes full use of fuel.

For achieving the above object, the utility model has adopted in the handwheel of a band hollow spiral shell, pass a valve seat, one end of valve seat is connected with a unidirectional intake valve, the other end is connected with spool, be provided with an O RunddichtringO between the boss on the spool and the end face of valve seat, the other end of spool is entangled by a spherical seal ring.

Because the unidirectional intake valve mouth of above-mentioned employing, devices such as the spherical seal ring of spool front end and locking handwheel, it is simple in structure, compact that this valve is had, easy to use, as long as just can make the air pressure in the gas cylinder bottle reach the effect that liquid gas liquid is gasified totally by common pump, economic benefit and social benefit are apparent in view, considerable.

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail

Accompanying drawing 1 is assembled to face figure for the Liquified gas pressurizing valve structure.

Embodiment one: as shown in Figure 1, the bolt 5 of a hollow is established on the left side of handwheel 6, a groove is milled with certain diameter in the center of handwheel 6, and valve seat 4 passes hollow bolt 5, and valve seat 4 and end are established a boss, with the groove fit on the handwheel 6, valve seat 4 right-hand members are connected with a unidirectional intake valve mouth 7, and the left end of valve seat 4 is connected with a spool 2, and a boss 3 is also established in the centre of spool 2, establish an O RunddichtringO 8 between the left side of boss 3 and valve Cuo 4, and the left end of spool 2 overlaps spherical seal ring 1.

Embodiment two: other are identical with embodiment one, only set up a barometer between valve seat 4 and unidirectional intake valve chew 7.

Using method: use liquid gas, in cold season, because of temperature is lower, cause the liquid gas in the gas cylinder bottle not to be gasified totally, using to seven, eighty per cant o'clock, can not continue again to use, in the time of such, use pressurizing valve, close cylinder valve during use, unload reduction valve, load onto pressurizing valve, open cylinder valve again, with common pump or air pump by pressurizing valve air feed in steel cylinder, unidirectional air inlet because of pressurizing valve, so the air pressure in the steel cylinder constantly raises, when rising to 1kg or pump when beating 30-40 time when boosting, just can reach bottle effect that interior liquid is gasified totally, like this, close cylinder valve again, unload pressurizing valve, load onto reduction valve, just can normally make and use up combustable liquid in the steel cylinder, avoid, often give the trouble formality of steel cylinder preheating during use repeatedly earlier because of low temperature can not be gasified totally, like this, disposable just can reaching makes bottle effect that interior combustable liquid is gasified totally.

Claims

1, a kind of Liquified gas pressurizing valve, it comprises spherical sealed picture (1), handwheel (6), it is characterized in that: the bolt (5) that a hollow is arranged on handwheel (6) one end faces, valve seat (4) passes the bolt (5) that handwheel (6) is gone up hollow, one end of valve seat (4) is connected with a unidirectional intake valve mouth (7), and this end has a boss, annotated by handwheel (6) retaining, the other end is connected with spool (2), one diameter is arranged at least greater than the boss (3) of the diameter of valve seat (4) in the middle of the spool (2), be provided with an O RunddichtringO (8) between between the end of boss (3) and valve core case, the other end of spool (2) has spherical sealing to roll up (1) to entangle.

2, Liquified gas pressurizing valve according to claim 1 is characterized in that: can establish a barometer between valve seat (4) and unidirectional intake valve mouth (7).
