Abstract

The utility model relates to fully-automatic energy-saving safety device of fuel gas comprising a casing; wherein the two end of the casing is the air intake end and the air bleed end respectively. The inner cavity of the casing is separated into a left air chamber and a right air chamber by a partition; the partition and the left air chamber form a sealing connection. A slide bar goes into the right air chamber through the through hole in the center of the partition, and the end of the slide bar is fixed by a baffle; a spring is sleeved over the slide bar in the left air chamber and provided with a covering cap which fits and seals with the sealing connection; in the right air chamber, a magnetic slider is provided to fit with the slider bar; in addition, a magnetic ring corresponding to the magnetic slider is positioned outside of the casing. The utility model overcomes such defects as complex structure and low reliability of common fuel gas safety device in prior art, through the above design, the air supply may be cut off immediately when minor leakage is found in leather gas supplying hose (pipeline), while needing no external force and power supply, with the advantages of simple structure, easy assembly, long service life, energy-saving, environmental protection and high reliability and so on.

Description

The full-automatic safety device of economical gas

Affiliated technical field

The utility model relates to the full-automatic safety device of a kind of economical gas.

Background technique

Because combustion gas belongs to the clean and environment-friendly energy and aboundresources, the continuous enhancing with environmental consciousness of improving constantly along with people's living standard, combustion gas uses popularity rate also more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now since the various security incidents of using combustion gas to take place also get more and more.Although occurred multiple combustion gas security personnel product at present on market, these products all exist the defective that can not be ignored, and some has introduced solenoid valve in structure, but its structure is too complicated, and will lose all protection functions in case have a power failure; Some has introduced superfine spring in structure, repeatedly using rear spring that " distortion " can take place, and bigger change can take place spring force, thereby influences security personnel's performance of product greatly, even loses whole protection functions.

Summary of the invention

In order to overcome the complex structure of general gas safety device in the prior art, the problem that reliability is lower, the utility model provides a kind of automatic protecting gas fuel device, this automatic protecting gas fuel device simple in structure, need not external force and power supply supply, safe and reliable, the effect that has energy-saving and environmental protection concurrently.

The technological scheme that its technical problem that solves the utility model adopts is: comprise housing, the two ends of housing are respectively inlet end and outlet side, the housing inner chamber is divided into left air chamber and right air chamber by the next door, form sealed interface between next door and the left air chamber, the through hole that slide bar passes the center, next door enters right air chamber, the end is fixed by baffle plate, slide bar end in the air chamber of a left side is provided with the block that is sealed and matched with sealed interface, be provided with the magnetic slider that matches with slide bar in the right air chamber, the outer setting of the housing slip magnet ring relative with magnetic slider.

Slide bar outer casing spring in the air chamber of a left side.

The utility model is by above-mentioned specific design, can eradicate thoroughly that gas transmission leather hose (pipeline) comes off because of taking place when using combustion gas, aging cracking, the security incident of breaking etc. and to cause, and do not need any external force and power supply supply, also can cut off source of the gas immediately automatically even trickle gas leakage takes place, have the advantage of simple in structure, easy to assembly, long service life, energy-saving and environmental protection, good reliability in gas transmission leather hose (pipeline) section.

Description of drawings

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

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

Fig. 2 is another embodiment's two of the utility model a structural representation;

Fig. 3 is another embodiment's three of the utility model a structural representation.Embodiment:

As shown in Figure 1, the utility model comprises housing 1, the two ends of housing 1 are respectively inlet end 2 and outlet side 3, housing 1 inner chamber is divided into left air chamber 5 and right air chamber 6 by next door 4, form sealed interface 7 between next door 4 and the left air chamber 5, the through hole 9 that slide bar 8 passes 4 centers, next door enters right air chamber 6, the end is fixing by baffle plate 10, slide bar 8 ends in the air chamber 5 of a left side are provided with the block 12 that is sealed and matched with sealed interface 7, slide bar 8 outer casing springs 11 in the air chamber 5 of a left side, be provided with the magnetic slider 13 that matches with slide bar 8 in the right air chamber 6, housing 1 is outer to be provided with the slip magnet ring 14 relative with magnetic slider 13.Under normal air feed situation shown in Figure 1, the utility model level is installed, and combustion gas can enter right air chamber 6 by through hole 9 is smooth and easy from left air chamber 5.Can be when magnetic slider 13 and slip magnet ring 14 positions are passed through in combustion gas again by magnetic field magnetisation, the combustion gas micel can be become more even by refinement atomizing, molecules align, thereby raising combustion efficiency, make fuel gas buring more abundant, reduced discharge of harmful gases effectively, both played energy saving, effect that again can the clean environment.If because of aging cracking takes place in gas transmission leather hose (pipeline), break, the gas leakage that comes off etc. and cause, then right air chamber 6 can be because of obtaining from left air chamber 5 through 12 other and enough gas make-up (12 the restrictions owing to block a shot that through hole 9 is come of blocking a shot in moment, the peak rate of flow that flows into right air chamber 6 from left air chamber 5 just also has only or is slightly larger than the required peak rate of flow of gas range normal combustion), being directed at right air chamber 6 air pressure die-offs, and the air pressure of left air chamber 5 does not almost have change in a flash at this, the pressure that makes block 12 overcome spring 11 moves rapidly and tightly is attached on the sealed interface 7, thereby be implemented in the automatic source of the gas that cuts off of moment, reach the automatic protecting purpose.Spring 11 can be selected extension spring for use, but 12 the mounting point of blocking a shot needs respective change, and its structure as shown in Figure 3.If think vertical installation, its structure can be omitted the design of spring 11 as shown in Figure 2.After finding and getting rid of the gas leakage accident, think to recover again normal air feed, only with hand promotes slip magnet ring 14, slip magnet ring 14 drives the end of magnetic slider 13 pushing tow slide bars 8, block 12 and sealed interface 7 are broken away from, and the gas in the left air chamber 5 can enter right air chamber 6 rapidly, makes the right air chamber 6 and the gas pressure of left air chamber 5 reach balance again, again recover normal air feed, realize automatic, efficient, reliable protection function.
