The purpose of this utility model is at above-mentioned deficiency, a kind of improved multifunctional domestic LPG pressure regulator is provided, it can not be subjected to the influence of the gas what (being the air pressure height) in the steel cylinder effectively and keeps the flame unanimity, particularly under subzero 20 ℃ situation, also liquid can be used up (because of makings band water, matter difference do not have except the burning capacity), and at safety anti-explosive, leak hunting, storage shows, decompression, super stream function aspects such as cut-outs automatically, all can meet the standard of the JYT-0.6D type of country's formulation.

The purpose of this utility model is achieved in that by air flue, connection switch, barometer, valve body, valve gap and the mechanism of decompressor to be formed, at the air flue that is positioned at the valve pipe is a stepped shaft clear opening, its outlet aperture is 1.5～2.0 millimeters, with 1.8 millimeters for well, valve block internal diameter is not less than 62 millimeters, in the mechanism of decompressor, left end head with the pull bar of finger setting, have a notch, this notch is stuck on the axis body that links to each other with valve head right-hand member trough rim, the right-hand member head links to each other with link rod, and the shaft axis that the left end of valve head is embedded with sealing gasket and itself and clear opening is in together on the horizontal line.

Above-mentioned valve head is copper, and its left end is a cuboid.There is a shaft shoulder at the middle part of link rod, and the following body of rod of its shaft shoulder passes the middle part of diaphragm, membranous disc successively, and is fixed with nut.

The utility model is because improved the manner of execution of envelope gas or air inlet, it is the sealing gasket on the valve head, push-and-pull by pull bar, and be to be plane contact in the horizontal direction or to leave all the time with the gas port of valve pipe, available liquid in the steel cylinder can be burnt down (this can learn) from barometer so envelope gas is tight, intake velocity one is made peace, connect the strong cooperation of switch in addition, consequently precision of voltage regulation height, safe and reliable and explosion-proof performance good; Again because improved the air flue trend, be that the interior air flue of valve pipe is the clear opening that does not have the turning, and suitably determined the outlet aperture of air flue and strengthened valve body decompression chamber internal diameter, so air-flow operates steadily, holds more than the gas and rated flow (has promptly reached the 0.6m of JYT-0.6D type greatly ³The standard of/h).What deserves to be mentioned is; because the utility model is reasonable in design; and taken the lead in the whole nation, getting the traffic permit of gas inspection center of Ministry of Urban and Rural Construction and Environmental Protection; promptly according to JYT-0.6D type standard detection; various important performance index are all qualified, thereby can come into operation on the gas range in family, hotel and restaurant.

Concrete device of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A of Fig. 1---the A sectional drawing;

Fig. 3 is the mechanism of decompressor schematic representation of prior art.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1: the two ends of valve pipe 6 and the body that is with handwheel link to each other with inlet union, valve body 11 and connection switch 1, barometer (not marking among the figure) screw thread respectively.Air flue in the valve pipe 6, be one by slightly, thick, the thin trapezoidal clear opening of order order of a permutation: safe chamber is arranged on the gross porosity road, a grade pearl spring 2, steel ball 3 and O RunddichtringO 4 is arranged in the chamber, be equipped with on its side opening and connect switch 1; Than a side opening that communicates with barometer 5 is arranged on the gross porosity road; [aperture (being the air flue outlet aperture) is 1.5～2.0 millimeters, and is best with 1.8 millimeters.Connect the structure of switch 1 and the safety control effect that super stream cuts off thereof, can show the barometer of the storage and the gas leakage detection effect of liquid gas in the steel cylinder, and all same prior art of their working principle.

As shown in Figure 1 and Figure 2, left side section is the copper valve head 8 that cuboid, right section have groove, slide in its vestibule that can be communicated with at the chamber (being the underpressure chamber) with valve body 11, and its left end head embedding is connected with sealing gasket 7, is installed with spools 10 on the trough rim of right-hand member head.The underpressure chamber internal diameter is not less than 62 millimeters, too little can influence some performance index (such as rated flow).The mechanism of decompressor is housed in the underpressure chamber, and the left end head with the pull bar 18 of pin 9 location has a vertical slot mouth that can block axle 10, and the right-hand member head inserts in the body of rod groove on shaft shoulder top of link rod 22; The following body of rod of link rod 22 shaft shoulders passes diaphragm 24, membranous disc 23 and packing ring successively, fixes it with nut again, and they support by the pressure adjusting spring 20 that rests on the adjusting screw dish 21; It links to each other adjusting screw dish 21 and valve gap 25(with valve body 11) middle part boss screw thread link to each other, seal with covering 19 again; Pin 9 leans on the column 13 that is connected with valve body 11 to support.
