Abstract

The utility model provides a liquefied gas residue utilizing device, which is connected with the lower end of the inner angle valve in a liquefied gas steel cylinder, the device is composed of a fixed valve seat, a valve core, a suction tube, a spring, a bottom cover of the valve seat and a gas phase hole, using the pressure difference between the upper part of the valve core and the bottom of the steel cylinder, to press the liquefied gas residue, which deposits on the bottom of the steel cylinder, into the suction tube, making the residue eject out, and vaporing the residue which is sent out mixed with the original liquefied gas, thereby, solving the problem of unavailable of the liquefied gas residue.

Description

The liquefied gas residue combustion device

The utility model relates to a kind of utilized device of bottled gas raffinate.

Sell in the market and the employed liquified petroleum gas cylinder of users by steel cylinder and on angle valve form, when opening valve, the interior liquid gas of steel cylinder burns to stove and accessory by reduction valve and pipeline.Because liquefied gas residue is difficult for vaporization, proportion is big again, thereby is deposited on the steel cylinder bottom, can not be utilized, and has caused the loss of the energy.The raffinate that is deposited on the bottom simultaneously can influence the can amount of liquid gas next time again, thereby need take out residual equipment raffinate is extracted out, causes the liquid expense of human and material resources.

The purpose of this utility model is to provide a kind of liquefied gas residue complete hurning device that is connected common cylinder angle valve lower end, and it can draw up the raffinate of steel cylinder bottom and spray, and makes it easily vaporization and obtains utilizing.

Be used to realize that the technological scheme of this novel purpose is: the angle valve lower end connects a liquefied gas residue combustion device of being made up of fixed valve base, spool, suction pipe, spring, valve cup bottom benefit and gas phase hole etc. in common liquified petroleum gas cylinder.The structure of this device is such: what be fixed on the angle valve lower end is on one, under be communicated with fixed valve base, its side wall upper part has by certain regularly arranged some apertures, have in the valve seat on the energy, mobile down spool, spool moves up can the closed valve seat passage and the sidewall aperture, on having on the spool, the non-central gas phase hole that communicates down, center spool also has a gas phase hole, center that joins with the suction pipe that stretches to the steel cylinder bottom, be with spring and valve seat bottom on the suction pipe, spring can be pressed on valve seat top to spool, the fastening driving fit of bottom and valve seat, also have on the bottom and the corresponding gas phase of spool hole.

During the can liquid gas, the high pressure vapour of liquefied gas station pushes spool, and liquid gas enters in the steel cylinder by valve seat sidewall aperture, and can finishes, and the upper and lower liquid gas mixed state of spool air pressure tends to balance, and the spring handle spool is pushed to, and has sealed valve base channel and sidewall aperture.

When using liquid gas, open high pressure valve, on the spool, on produce pressure difference, liquid gas is by the gas phase hole on the bottom in the bottle, non-central gas phase hole enters pipeline on spool again, forms steam flow.Simultaneously, under the differential pressure action between spool top and the suction pipe bottom, the raffinate that is deposited on the big proportion in steel cylinder bottom is inhaled in the pipe, by the ejection evaporation of center spool gas phase hole, vaporization, and is mixed output to the stove and accessory burning with above-mentioned liquid gas flow and utilizes.

An energy drew up liquefied gas residue and urgees the raffinate combustion device of its vaporization on the angle valve lower end connected in common cylinder for liquefied gas, can make the raffinate vaporization and export burning utilization simultaneously with liquid gas, overcome the unavailable shortcoming of raffinate in the former steel cylinder, thereby improved fuel availability, saved the residual equipment of taking out simultaneously.This apparatus structure is simple, and cost is low, and is safe and reliable.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is each modular construction schematic representation of an embodiment of the utility model.

Fig. 2 is an embodiment's of the utility model an assembly schematic cross-section.

At Fig. 1, in the raffinate combustion device shown in Figure 2, fixed valve base 1 can be with being threaded in the angle valve lower end, valve seat 1 side wall upper part is inclined and is lined up circle on the face, equally distributed eight apertures 2, have in the valve seat 1 on the energy, mobile down spool 3, on having on the spool 3, three non-central gas phase holes 4 that communicate down and gas phase hole, a center 5, gas phase hole, center 5 is identical with 4 apertures, non-central gas phase hole, be valve seat 1 sidewall aperture 2 the aperture 1/5, gas phase hole, center 5 joins with the suction pipe 6 that stretches to the steel cylinder bottom, the length of suction pipe 6 is advisable with difference 2-3cm at the bottom of steel cylinder, be with spring 7 and valve seat bottom 8 on the suction pipe 6, bottom 8 is used threaded closure with valve seat 1, and three gas phase holes 4 are also arranged on the bottom 8, and spring 7 is pressed on spool 3 on the top of valve seat 1.

During inflation, high pressure air pushes spool 3, and liquid gas enters steel cylinder by valve base channel and eight apertures 2 of sidewall, can finishes, the upper and lower liquid gas mixed state air pressure of spool 3 balances each other, and spring 7 presses the top of valve seat 1 to spool 3, thereby has sealed passage and eight apertures 2 of sidewall of valve seat 1.

When using gas, open high pressure valve, liquid gas is by three gas phase holes 4 on the bottom 8 in the bottle, and the non-central gas phase hole 4 of footpath spool 3 enters pipeline again, forms steam flow.Simultaneously, under the differential pressure action of steel cylinder inner spool 3 tops and steel cylinder bottom, the bottom raffinate is sucted suction pipe 6, and sprays evaporation, vaporizes and export utilization simultaneously with liquid gas by the gas phase hole, center 5 of spool 3 rapidly.
