Abstract
For solve gravity type explosion vents seal is poor, automatic homing is unable to after pressure release, the weight of excessively dependence protective cover causes waste of material and it is excessively heavy the shortcomings that, the present invention improves, there is provided a kind of torsion spring gravity type explosion proof door, it is characterised in that：Including flanged plate, torsion spring, protective cover; the flanged plate is fixedly mounted on the sleeve of boiler tail and is connected with explosion proof door protective cover with torsion spring; the outlet of the explosion proof door is inclined to set and is covered with protective cover; the flanged plate edge is provided with groove and the edge protrusion of protective cover is adapted, and the edge protrusion of the protective cover is high temperature resistant elastic material.
Description
Technical field
The invention 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 defects 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 boiler can be threatened.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 up when detonation occurs for the fuel gas in burner hearth or flue, and gases at high pressure caused by detonation are put
Go out a part, thus pressure release and protect boiler not by heavy damage.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, and three kinds of explosion proof doors are 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
The defects of 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, it is necessary to which automatic water-replenishing device causes complicatedization, no under high temperature
Enough compact and initial outlays are big.Gravity type explosion proof door, be widely used one kind is simple in construction, easily manufactured, take-off flexibly and
Automatically reset, the pattern that security is good, boiler operatiopn is not influenceed during startup, shortcoming is that sealing difficulty is big, easily leaked out, reduction stove
Effect is, it is necessary to further improve, raising sealing, and reduce maintenance cost, being allowed to after pressure release can automatic homing.
The content of the invention
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
The defects of, the present invention provides a kind of torsion spring gravity type explosion proof door of energy automatic homing after simple in construction, good airproof performance, pressure release, is
The improvement done on the basis of typical round gravity type explosion proof door, it is characterised in that：It is described including flanged plate, torsion spring, protective cover
Flanged plate is fixedly mounted on the sleeve of boiler tail and is connected with explosion proof door protective cover with torsion spring, and the outlet of the explosion proof door is in
It is obliquely installed and is covered with protective cover, the flanged plate edge is provided with groove and the edge protrusion of protective cover is adapted, the protection
The edge protrusion of 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 torsion spring setting in the present invention not only acts as the work of automatic homing after pressure release
With, can also make up excessively relied in traditional approach protective cover weight cause waste of material and it is excessively heavy the shortcomings that, and turn round
The index of correlation of spring can select as needed, so as to further expand the use range of the present invention.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the present invention.
Fig. 2 is the schematic perspective view of the present invention.
Wherein：1- torsion springs, 2- protective covers, 3- explosion proof doors.
Embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
Consolidate referring to Fig. 1, Fig. 2 a kind of torsion spring gravity type explosion proof door, including flanged plate, torsion spring, protective cover, the flanged plate
Dingan County is connected on the sleeve of boiler tail and with explosion proof door protective cover with torsion spring, and the outlet of the explosion proof door is inclined to set
And protective cover is covered with, the flanged plate edge is provided with groove and the edge protrusion of protective cover is adapted, the edge of the protective cover
Protrude for polytetrafluoroethylene (PTFE).
Claims (2)
- A kind of 1. torsion spring gravity type explosion proof door, it is characterised in that：Including flanged plate, torsion spring, protective cover, the flanged plate fixes peace It is connected on the sleeve of boiler tail and with the protective cover with torsion spring, the protective cover covers on the explosion proof door being obliquely installed and gone out On mouth, the edge protrusion that the flanged plate edge is provided with groove and the protective cover is adapted, the edge protrusion of the protective cover For high temperature resistant elastic material.
- A kind of 2. torsion spring gravity type explosion proof door as claimed in claim 1, it is characterised in that：The high temperature resistant elastic material is poly- Tetrafluoroethene.
