Abstract
The utility model is related to a kind of torsional spring gravity type explosion proof doors; including flanged plate, torsional spring, protective cover; the flanged plate is fixedly mounted on the sleeve of boiler tail and is connect with torsional spring with explosion proof door protective cover; the outlet of the explosion proof door is inclined to set and is covered with protective cover; the flanged plate edge is equipped with groove and the edge protrusion of protective cover is adapted; the edge protrusion of the protective cover is high temperature resistant elastic material, solves the disadvantage that the weight that gravity type explosion vents seal is poor, is unable to automatic homing after pressure release, excessively relies on protective cover leads to waste of material and excessively heaviness.
Description
Technical field
The utility model belongs to heating equipment field more particularly to a kind of gravity type anti-explosive door for boiler.
Background technology
With extensive use of the fuel-oil or fuel-gas boiler in modern industry, traditional fire coal boiler fume is overcome to air
The defect of pollution, alleviate the severe situation of environmental pollution, but also association another problem, i.e. boiler abnormal operational conditions
When burner hearth in flammable gas explosion can threaten to boiler.Therefore, general fuel oil and gas fired-boiler are designed with explosion proof door.It is anti-
The effect of quick-fried door is automatically opened when detonation occurs for the fuel gas in burner hearth or flue, and the high pressure gas that detonation generates is put
Go out a part, thus pressure release and protect boiler not destroyed seriously.The unlatching promptness of explosion proof door, safety release pressure and
Sufficient pressure release area is vital.
Common explosion proof door pattern has diaphragm type, hydrolock, gravity type, three kinds of explosion proof doors with their own characteristics.Diaphragm type is explosion-proof
Door sealing is good, but the accuracy of manufacture and material requirements are high, and burst pressure is affected by many factors, is not sufficiently stable and accurately.It is maximum
Defect be to need to reinstall diaphragm after explosion, influence the continuous operation of boiler.Hydrolock explosion vents seal is good, after unlatching
Automatic-sealed does not influence boiler operatiopn, but sealing fluid evaporation is fast under high temperature, needs automatic water-replenishing device to make complicatedization, no
Enough compact and initial outlays are big.Gravity type explosion proof door, be widely used one kind is simple in structure, easily manufactured, take-off flexibly and
It automatically reseting, the pattern that safety is good, when startup, does not influence boiler operatiopn, the disadvantage is that sealing difficulty is big, easily leaks out, reduction stove
Effect, requires further improvement, and improves leakproofness, and reduce maintenance cost, and being allowed to after pressure release can automatic homing.
Utility model content
In order to solve in the prior art, gravity type explosion vents seal is poor, maintenance cost is high, is unable to automatic homing after pressure release
Defect, the utility model provide after a kind of simple in structure, good airproof performance, pressure release can automatic homing torsional spring gravity type it is explosion-proof
Door, is the improvement done on the basis of typical round gravity type explosion proof door, it is characterised in that：Including flanged plate, torsional spring, protection
Cover, the flanged plate are fixedly mounted on the sleeve of boiler tail and are connect with torsional spring with explosion proof door protective cover, the explosion proof door
Outlet be inclined to set and be covered with protective cover, the flanged plate edge is equipped with groove and the edge protrusion of protective cover is adapted,
The edge protrusion of the protective cover is high temperature resistant elastic material.
Further, the high temperature resistant elastic material is polytetrafluoroethylene (PTFE).
Compared to typical round gravity type explosion proof door, the torsional spring setting in the utility model not only acts as automatic homing after pressure release
Effect, can also make up and excessively rely on the weight of protective cover in traditional approach and lead to waste of material and excessively heavy disadvantage,
And the index of correlation of torsional spring can select as needed, to further expand the use scope of the utility model.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is the stereoscopic schematic diagram of the utility model.
Wherein：1- torsional springs, 2- protective covers, 3- explosion proof doors.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and detailed description.
Referring to a kind of torsional spring gravity type explosion proof door of Fig. 1, Fig. 2, including flanged plate, torsional spring, protective cover, the flanged plate is solid
Dingan County is connect on the sleeve of boiler tail and with explosion proof door protective cover with torsional spring, and the outlet of the explosion proof door is inclined to set
And it is covered with protective cover, the flanged plate edge is equipped with groove and the edge protrusion of protective cover is adapted, the edge of the protective cover
Protrusion is polytetrafluoroethylene (PTFE).
Claims (2)
1. a kind of torsional spring gravity type explosion proof door, it is characterised in that：Including flanged plate, torsional spring, protective cover, the flanged plate fixes peace
It is connect on the sleeve of boiler tail and with explosion proof door protective cover with torsional spring, the protective cover covers on the explosion proof door being obliquely installed
In outlet, the edge protrusion that the flanged plate edge is equipped with groove and the protective cover is adapted, and the edge of the protective cover is convex
Go out for high temperature resistant elastic material.
2. a kind of torsional spring gravity type explosion proof door as described in claim 1, it is characterised in that：The high temperature resistant elastic material is poly-
Tetrafluoroethene.
