Abstract
The utility model discloses a combined valve device which is used for gasifying flammable gas, belonging to a pipeline attachment in the gas and chemical field. Presently, some flammable liquid with less capabilities of gasification, such as petroleum liquid gas raffinate, is used after heating and gasification. The use is troubled, and the safety is difficulty ensured. The solution of the utility model is that a valve core sealing shaft which is bored with a through hole is installed for replacing on the valve body of an original gas cylinder; gas which is conveyed by a gas-infusion device is directly conveyed to the bottom of the gas cylinder to discharge through the through hole of the valve core sealing shaft and a gas pipe which is connected with the through hole; the movement of the raffinate of the gas is disturbed by the gas; appropriate gas pressure is generated in the gas cylinder; the decomposition and gasification of the raffinate in the gas cylinder is expedited; thereby, the purpose of use is achieved.
Description
The utility model belongs to the pipeline fittings in the burning field.
At present, some combustable liquids are after liquid gas uses up as the liquefied petroleum gas raffinate, and the raffinate in the gas cylinder mostly is to adopt the heating way to carry out heating and gasifying, or outwells waste, have not only used trouble but also very dangerous, also befouling environment.
The purpose of this utility model is for for using the huge numbers of families of liquid gas at present, provides a kind of do not changing gas cylinder and do not changing under the situation of valve body, the security combination control valve unit that can use liquid gas remaining fluid can be used again.
The main design of gasification combustable liquid combined valve device (hereinafter to be referred as combination brake switch and proporting) is: adopt on the valve body of former liquid gas bottle, install and change a seal spool axle that occupies through hole, make it by the qi of chong channel ascending adversely device to the gas cylinder inner bottom part conveying gas that raffinate is housed, come its liquid motion of disturbance by gas.Make to produce suitable air pressure in the gas cylinder, quicken the interior raffinate of bottle and decompose gasification, thereby achieve the above object.
Be illustrated referring now to accompanying drawing.
From accompanying drawing as can be seen, combination brake switch and proporting divides four parts to form: main valve, pneumatic tube, heading valve and qi of chong channel ascending adversely device.
Combination brake switch and proporting is mounted on the former valve location of gas cylinder (8), in valve body of main valve (7) and the circumference that gas cylinder (8) cooperates, one through hole is arranged, the seal spool axle (3) that one usefulness screw thread cooperates with valve body (7) is housed in the through hole on valve body (7) top, a through hole is occupied at the center of the close axle of this spool, the upper end is connected and installed with a suction valve (1), the lower end is connected and installed with a tracheae (6), and this tracheae extends to the interior bottom of gas cylinder (8) by the above-mentioned through hole of valve body (7) always.A vent plug (4) that can prevent gas backstreaming also is housed in the through hole of seal spool axle (3), sees accompanying drawing.
When the very little combustable liquid of vaporization ability is housed in the gas cylinder, operating process and combination brake switch and proporting structural principle are: at first tighten handle (2) drive seal spool axle (3) and move downward, the seal spool pad (14) and the feed liquor exhaust port of valve body (7) are sealed, close main valve.Turn on the pneumatic tube insertion tube joint (11) of suction valve (1) with the qi of chong channel ascending adversely device beginning qi of chong channel ascending adversely in bottle then.Gas is washed vent plug (4) open and is entered tracheae (6) then up to discharge of gas cylinder (8) bottom and liquid (9) mixing gasifying in the through hole of the air flue hole of suction valve (1) direct admission valve core seal shaft (3).See accompanying drawing 1.
By experiment, when the air pressure of rushing in the gas cylinder reached suitable, the liquid in the bottle just began to quicken gasification.At this moment just can turn on handle (2) has brought into use.Certainly, the qi of chong channel ascending adversely device also needs constantly conveying gas in bottle, to keep the air pressure balance in the gas cylinder.When the air pressure in the gas cylinder during greater than the air pressure carried, at this moment vent plug (4) is by the pore of the effect self-blocking seal spool axle (3) of spring (5) and back pressure, thereby reached the unidirectional effect of only import but no export.When not in use, should close two valves.
As when re-using the very strong liquid gas of vaporization ability, should close suction valve (1), and for attractive in appearance and easy to use, also can will fall under the suction valve (1), the blind hole nut (10) of screwing on seal spool axle (3) compresses sealing gasket (13) with its bore closure.See accompanying drawing (2).
The utlity model has convenient use, effective, characteristics such as low cost of manufacture.
Claims (1)
- A kind of gasification combustable liquid combined valve device is by main valve, tracheae, suction valve and qi of chong channel ascending adversely device are formed, it is characterized in that: an outer first threaded seal spool axle (3) is equipped with on the through hole top in the circumference that valve body of main valve (7) cooperates with gas cylinder (8), the axle center of this seal spool axle (3) is drilled with a through hole and the upper end is connected and installed with a suction valve (1), cylindrical is with one handle (2), the lower end is connected and installed with a tracheae (6) and is embedded with a seal spool pad (14), the feed liquor exhaust port that tracheae (6) is inserted through valve body (7) extends to the bottom in the gas cylinder (8) always, and a vent plug (4) that can prevent gas backstreaming also is housed in the through hole of seal spool axle (3); The gas that above-mentioned qi of chong channel ascending adversely device is carried enters in the through hole of seal spool axle (3) through the air flue hole of air valve (1), washes vent plug (4) open and enters tracheae (6) then and discharge up to gas cylinder (8) inner bottom part.
