Abstract

The utility model relates to a furnace end fire lid, including socket pipe, bayonet joint and activity strip, socket pipe cup joints the top at the furnace end outlet duct to protruding muscle together through pipe wall in it is established is fixed on the furnace end outlet duct, the bayonet joint is pegged graft on socket pipe's top through its a plurality of grafting feet of establishing of bottom, and its a plurality of grafting feet set up, and whenever all separate into a play burner between two liang along the annular, the equal bottom of a plurality of grafting feet is straight, fixes the bayonet joint top surface of the protruding muscle of pipe wall in socket pipe, activity strip sets up in the through -hole that established at the bayonet joint top movablely, and two all is equipped with respectively and prevents its last screens piece that breaks away from the through -hole and lower screens piece about it. The utility model discloses a split type structure, can avoid gas pressure explode towards the time whole fire lid liftd by the gas and the gas that leads to is leaked dangerously, the utility model discloses simple structure, low cost, application scope is extensive.

Description

Stove burner fire cover

Technical field

The utility model relates to gas furnace, particularly relates to a kind of stove burner fire cover of gas furnace.

Background technology

When the combustion gas internal pressure that gas furnace uses is uneven, pressure raises suddenly, combustion gas in its escape pipe upwards quick-friedly can rush fire cover, common gas furnace, due to its stove burner fire cover lighter in weight, and be the integrated design, fire cover may be washed from escape pipe by the combustion gas of upwards quick-fried punching, thus causes flare to stop working, combustion gas directly leaks, and forms potential safety hazard.

Utility model content

The utility model is intended to the above-mentioned defect solved existing for the stove burner fire cover of existing gas furnace.

The technical solution of the utility model is as follows:

Scheme one:

A kind of stove burner fire cover, comprises socket pipe, connection-peg and activity bar;

Described socket pipe is socketed in the top of burner escape pipe, and is fixed on burner escape pipe by one convex tendon set by its inner tubal wall;

Described connection-peg is plugged on the top of described socket pipe by multiple inserting foots set bottom it, and its multiple described inserting foot annularly arranges and is often all divided into a crater between any two; The equal bottom flat of multiple described inserting foots, is fixed on the end face of the described convex tendon of described socket pipe inner tubal wall by described connection-peg;

Described activity bar is arranged in the through hole set by described connection-peg top actively, and its upper and lower two is all respectively equipped with and prevents its upper screens sheet departing from described through hole and lower screens sheet.

Scheme two:

Described socket pipe is socketed in the top of burner escape pipe, one groove that its inner tubal wall is provided with;

Described connection-peg is plugged on the top of described socket pipe by multiple inserting foots set bottom it, its multiple described inserting foot annularly arranges and is often all divided into a crater between any two, be equipped with outside flanging bottom multiple described inserting foot, described connection-peg can be fixed in the described groove of described socket pipe inner tubal wall;

Described socket pipe is fixed on burner escape pipe by the bottom of the multiple described inserting foot of described connection-peg;

Compared to like product before, the utility model have employed split-type structural, especially the employing of activity bar is benefited from, gaseous-pressure is quick-fried rush time, by the upwards activity of activity bar, expand the passage that fires of connection-peg surrounding crater, can by the gaseous-pressure abrupt release of quick-fried punching, avoid and raised by combustion gas due to whole fire cover and the gas leakage that causes is dangerous.The utility model structure is simple, with low cost, applied widely.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described.

Embodiment 1

See figures.1.and.2:

A kind of stove burner fire cover, is characterized in that: comprise socket pipe 1, connection-peg 2 and activity bar 3;

Described socket pipe 1 is socketed in the top of burner escape pipe, and is fixed on burner escape pipe by one convex tendon 101 set by its inner tubal wall;

Described connection-peg 2 is plugged on the top of described socket pipe 1 by multiple inserting foots 201 set bottom it, and its multiple described inserting foot 201 annularly arranges and is often all divided into a crater 202 between any two; Multiple described inserting foot 201 is bottom flat all, described connection-peg 2 is fixed on the end face of the described convex tendon 101 of described socket pipe 1 inner tubal wall;

Described activity bar 3 is arranged in the through hole 203 set by described connection-peg 2 top actively, and its upper and lower two is all respectively equipped with and prevents its upper screens sheet 301 departing from described through hole 203 and lower screens sheet 302.

Embodiment 2

With reference to Fig. 1 and Fig. 3:

Described socket pipe 1 is socketed in the top of burner escape pipe, one groove 102 that its inner tubal wall is provided with;

Described connection-peg 2 is plugged on the top of described socket pipe 1 by multiple inserting foots 201 set bottom it, its multiple described inserting foot 201 annularly arranges and is often all divided into a crater 202 between any two, be equipped with outside flanging bottom multiple described inserting foot 201, described connection-peg 2 can be fixed in the described groove 102 of described socket pipe 1 inner tubal wall;

Described socket pipe 1 is fixed on burner escape pipe by the bottom of the multiple described inserting foot 201 of described connection-peg 2;

With reference to Fig. 4 and Fig. 5: when normally using, activity bar 3 is hung in the through hole 203 at connection-peg 2 top by screens sheet 301 on it, once the quick-fried punching of combustion gas, activity bar 3 moves upward rapidly under the impact of combustion gas, until blocked by the lower screens sheet 302 of its bottom, the crater 202 area expanded of the blast tube in connection-peg 2 and surrounding thereof, rapid release gaseous-pressure, thus whole fire cover is still fixed on gas outlet pipe, though now flare has fluctuating, but can not extinguish, avoiding stops working causes gas leakage.Once gaseous-pressure stabilizes, activity bar 3 is descending under the effect of himself gravity, is reset to normal operating condition.
