Abstract

The utility model provides a three-way valve of petroleum liquified gas steel cylinder. The utility model is that a through pipe which extends into the steel cylinder is added in the exhaust hole of an original three-way valve; the periphery of the hole is provided with a circle of small holes; liquified gas is discharged from the small holes; however, raffinate is transferred from the through pipe to the outside, owing to the internal pressure action and volatility of the raffinate; the liquified gas and the raffinate is discharged to a gas supply pipe for the use of combustion, after the mixed. The structure is simple and safe. Raffinate can be fully and safely used to reach the goal of energy conservation.

Description

Three-way valve

The device that the liquid gas that the utility model relates to a kind of compression is discharged in the container, especially a kind of drain tap of liquid gas.

At present, general family mostly uses the liquefied petroleum gas (LPG) of steel cylinder can, at normal temperatures, unexhausted LPG (liquefied petroleum gas) residual liquid in the steel cylinder, the steel cylinder three-way valve that general family uses is difficult to utilize, and often when can again it is outwelled, so both pollute environment, also caused the waste of the energy; Also some family adopts the method for heating in order to utilize these raffinates as far as possible, and its result not only utilization ratio is low, and very dangerous.

The purpose of this utility model is to design a kind of three-way valve that can make the LPG (liquefied petroleum gas) residual liquid after-flame in order to overcome above-mentioned the deficiencies in the prior art part, as long as this kind three-way valve is installed on the liquefied petroleum gas bottle, it just can make the together mixed combustion of raffinate people having the same habits gas in the liquefied gas tank, the dangerous accident that can reach energy saving and prevent to bring when people from toppling over raffinate.

Task of the present utility model realizes that in the following way it is to transform on the basis of common angle valve, it mainly is to comprise siphunculus, threeway valve seat, spool, handle device, push rod, core retainer plate; Exhaust port at former three-way valve increases the copper pipe that can extend downwards, and increase a plurality of apertures around in this hole, so in use, liquid gas is from the outside air feed of aperture on every side of exhaust port, raffinate from the outside gas transmission of copper pipe, enters air supply pipe and uses for burning under internal pressure and the volatility effect of itself after the two mixes in the air supply opening of three-way valve.

The utility model has the following advantages compared with the prior art: it is equipped with the siphunculus that stretches in the jar in exhaust port, raffinate can easily be exported with good gas from pipeline be mixed together burning, it can make full use of raffinate in the jar, thereby reach energy-conservation purpose, safe and reliable again, simple in structure, realize that easily using effect is good.

Description of drawings:

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

Fig. 2 is the A-A sectional view of structural drawing of the present utility model;

Fig. 3 is the structural drawing of threeway valve seat 2 of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

As Fig. 1 and shown in Figure 3, it mainly is by passage 1, threeway valve seat 2, spool 3, handle device 4, push rod 5 and core retainer plate 6 are formed, siphunculus 1 is one one a bigger elongated hollow copper pipe, head has outside thread, threeway valve seat 2 is one a left side, the shoulder hole that right level communicates, being positioned at the horizontal hole middle part has vertical the communicating in a hole and it to constitute three through holes, the hole A that is positioned at the upright opening center left is a tapped hole, an equally distributed circle aperture is arranged around this hole, be preferably 6～8 apertures, being positioned at upright opening center right ports B is tapped hole, this hole left end head is semicircle ball-type hole, it with left side tapped hole A and on every side aperture communicate, the semi-round ball hole is positioned at the vertical centre lower end, and communicate threeway valve seat 2 left sides with it, on the cylindrical of right two ends outside thread is arranged all, spool 3 is that left end is the hemisphere face projection, right-hand member is the short double-screw bolt of positive square; Handle device 4 is made up of disc type handwheel, seal ring and hexagon nut, and push rod 5 is that two is the short cylindrical of positive square, and core retainer plate 6 is that inner chamber is the cylindrical sleeve in positive square hole; The siphunculus 1 that in the left hole A of threeway valve seat 2, has been threaded, a spool 3 and core retainer plate 6, push rod 5 and handle device 4 are housed has been threaded in the B hole on its right side; Valve seat 2 left ends are threaded with oil liquefied gas steel cylinder, siphunculus 1 extend to bottle interior at the bottom of bottle about 5cm highly locate, be connected with air supply pipe on the valve seat.When the turn handle device, spool 3 drives backspins at push rod 5 and core retainer plate 6 and transfers to left frontly to advance, the sphere and the ball hole of spool 3 are coincide, promptly close valve, otherwise being moved back, spool 3 promptly opens valve to the right, liquid gas is discharged from aperture, outwards gas transmission in the siphunculus 1 under suction that raffinate produces at the aperture place and the volatility acting in conjunction of itself, through the mixing of place, semi-sphere type hole to upright opening direction air feed.
