Abstract

The utility model provides a liquid discharging liquefied petroleum gas cylinder, which comprises a tank body and a switching valve, and is characterized in that the inlet of the switching valve is connected with a steel tube, and the terminal of the steel tube approaches to the inner bottom of the tank body. When the utility model is to be run, the liquid fuel enters the switching valve along the steel tube, being depressurized and supplied, so the residue in the tank body is decreased, and not only the loss of the fuel is reduced, but also the various malpractices, which are caused by pouring the residue, can be avoided, the utility model brings the convenience to users.

Description

Liquid discharging L.P.G cylinder

The utility model belongs to liquefied gas tank, is the improvement to existing liquefied gas tank.

Existing liquefied gas tank all is material gasification back discharge use in advance in jar when using gas from start to finish, abbreviates gas row formula liquefied gas tank as.Liquid gas is made up of 1～6 carbon alkane, and wherein 1～4 carbon alkane is gas under the room temperature condition of normal pressure, gasify gradually to discharge with gas the time to use, and 5～6 carbon alkane boiling points is higher.Be liquid at normal temperatures and pressures, can not gasify that therefore, use up remaining jar of end behind the gas, this part liquid fuel is called as raffinate.If remaining raffinate is not got rid of in jar, the aeration amount will reduce during aeration again, the raffinate amount with the number of times of aeration by the geometric ratio increase.The user often outwells these raffinates for fear of loss, and this processing method directly causes fuel loss, and What is more causes fire, sewerage blast, large size environmental pollution etc., causes the wealth wound of speaking sarcastically, neighbours' suffering.

The purpose of this utility model is in order to solve above-mentioned existing problems, a kind of liquid-draining type liquefied gas tank to be provided.It can realize the purpose with residual liquid burning out.

In order to achieve the above object, the utility model comprises tank body and open and close valve, it is characterized in that connecting a steel pipe at open and close valve inlet end, and the end of this steel pipe leans against the end in the tank body.

Distance is at 13～15mm at the steel pipe end-to-end distance tank body interior end.

During use, open the open and close valve after, the liquid fuel of tank base is entered in the pipe by the lower end of steel pipe, discharges along the open and close valve of passing through on the pipe, decompression gasification back is for using.In with the gas process, fuel is with the aqueous discharge of full component, when inner liquid level is reduced to the steel pipe end when following, the gas on top partly begins to efflux, simultaneously, the low boiling component also begins gasification in the still surplus partially liq in bottom, and the pressure in jar descends gradually, when treating that jar interior pressure and external pressure maintain an equal level, a liquid gas uses up in jar.At this moment, jar only surplus a spot of high boiling liquid in the end is about 1/tens of existing liquefied gas tank.And during jar gas, its quantity keeps constant, can not increase, and is atomic to the loss that the user causes, this advantage of the present utility model just once more.

Fig. 1 is a main sectional view of the present utility model.

(1) tank body; (2) open and close valve; (3) steel pipe.

Referring to Fig. 1, the external diameter of steel pipe (3) is 10mm, internal diameter is 6mm, be connected open and close valve lower inlet place by internal and external screw thread, the interior end of end-to-end distance tank body (1) of steel pipe (3) is 15mm, and the utility model can make the most of after-flame of the interior raffinate of tank body (1), has both reduced the loss of fuel, the all drawbacks that can avoid down raffinate again and brought are for the user has brought convenience.

Claims

1, a kind of liquid-draining type liquefied gas tank, it comprises tank body (1) and open and close valve (2), it is characterized in that connecting a steel pipe (3) at open and close valve inlet end, the end of this steel pipe (3) is near the end in tank body (1).

2, liquid-draining type liquefied gas tank according to claim 1, the distance at the interior end of end-to-end distance tank body (1) that it is characterized in that steel pipe (3) is at 13-15mm.
