Abstract

The utility model discloses a two-gas sharing valve core, consisting of a valve core body which is provided with a gas sources channel. One end of the gas sources channel is sealed. The utility model is characterized in that, the gas sources channel is provided with two cavities therein and a nozzle aperture is arranged between the two cavities. The two sides of the valve core body are provided with a and b gas sources inlet holes, wherein the gas sources inlet hole is connected to one cavity and the b gas sources inlet hole is connected to other cavity. The valve core of the utility model is provided with two kinds of gas sources inlet holes so that the structure deficiency exiting in the traditional valve when changing gas sources can be totally overcome, which ensures that no fittings is needed to be replaced when changing gas sources. Moreover, the utility model is safe and easy to use. At the same time unnecessary waste is avoided, thus greatly reducing the occurrence of catastrophic accidents, and better benefiting all mankind.

Description

A kind of two gas common valve plug

Technical field

The utility model relates to a kind of spool, and is particularly a kind of for two kinds of spools that source of the gas is shared.

Background technology

Because different combustion gas has different characteristics, its thermic load, combustion potential, Wobbe index ... etc. parameter difference is all arranged, therefore different combustion gas must be adopted different valves, thereby combustion gas is fully burnt, to maximally utilise the heat energy of combustion gas.Because traditional valve can only be used for a kind of source of the gas, if run into the situation that changes source of the gas, then must change valve again, or change the parts of valve internal, to reach the purpose that makes the smooth combustion on same burner of another kind of source of the gas, yet, such operation can make manufacturer and user feel very inconvenience, causes the significant wastage of resource simultaneously, if changed voluntarily by the user, then there is certain danger again, is directed at the generation of catastrophic failure easily.

Summary of the invention

In order to overcome the deficiencies in the prior art, it is a kind of for two kinds of spools that source of the gas is shared that the utility model provides.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of two gas common valve plug comprise valve core, are provided with the source of the gas passage in the described valve core, and the end sealing of described source of the gas passage is characterized in that being provided with in the source of the gas passage two chambers, is provided with a nozzle hole between two chambers; The both sides of described valve core are provided with a, b source of the gas air admission hole, and wherein a source of the gas air admission hole communicates with a chamber wherein, and b source of the gas air admission hole communicates with another chamber.

As the utility model improvement of the technical scheme, the other valve core of a source of the gas air admission hole is provided with the low baking temperature pore that corresponding chamber with it communicates, and the center line of low baking temperature pore and a source of the gas air admission hole is positioned on the same periphery; The other valve core of b source of the gas air admission hole is provided with the low baking temperature pore that corresponding chamber with it communicates, and the center line of low baking temperature pore and b source of the gas air admission hole is positioned on the same periphery.

One end of source of the gas passage of the present utility model can seal by sealed screw.

The beneficial effects of the utility model are: spool of the present utility model is provided with two kinds of source of the gas air admission holes, thereby structurally can overcome the deficiency that conventional valves exists fully when changing source of the gas, it has guaranteed need not change any accessory when changing source of the gas, and easy to use, safe; Avoid unnecessary waste simultaneously, thereby greatly reduced the chance that catastrophic failure takes place, thereby better benefited the whole mankind.

Fig. 2 is a front view of the present utility model;

Fig. 3 be among Fig. 2 A-A to cutaway view;

Fig. 4 be among Fig. 2 B-B to cutaway view.

The specific embodiment

With reference to Fig. 1, Fig. 2, the disclosed a kind of two gas common valve plug of the utility model, comprise valve core 1, in valve core 1, be provided with source of the gas passage 2, one end of source of the gas passage 2 is by sealed screw 3 sealings, be provided with in the source of the gas passage 2 between 22,23, two

chambers

22,23 of two chambers and be provided with a nozzle hole 4, be communicated with by nozzle hole 4 between the

chamber

22,23.

Valve core 1 is provided with a, b source of the gas

air admission hole

5,6, two source of the gas air admission holes are separately positioned on the both sides of valve core 1, and be separated with certain distance between between the center line of two source of the gas air admission holes, wherein a source of the gas air admission hole 5 communicates with chamber 22, and b source of the gas air admission hole 6 communicates with chamber 23; Nozzle hole 4 is the fumarole when using a source of the gas, and the fumarole when using the b source of the gas then is arranged on the valve body that uses this spool separately.When the utility model when using a source of the gas, then b source of the gas air admission hole is blocked sealing by the inwall of valve body, and a source of the gas that is using can not enter spool by b source of the gas air admission hole.Because the utility model is provided with the air intake structure that adapts to a, the burning of b source of the gas respectively, thereby structurally can overcome the deficiency that conventional valves exists fully when changing source of the gas, it has guaranteed need not change any accessory when changing source of the gas, and easy to use, safe; Avoid unnecessary waste simultaneously, thereby greatly reduced the chance that catastrophic failure is sent out, thereby better benefited the whole mankind.

With reference to Fig. 3, Fig. 4, a source of the gas air admission hole 5 other valve cores are provided with the low baking temperature pore 51 that communicates with chamber 22, and low baking temperature pore 51 is positioned on the same periphery with the center line of a source of the gas air admission hole 5; B source of the gas air admission hole 6 other valve cores are provided with the low baking temperature pore 61 that communicates with chamber 23, and low baking temperature pore 61 is positioned on the same periphery with the center line of b source of the gas air admission hole 6.
