Abstract
The utility model discloses a spring type anti-explosive door for boiler, wherein it is installed on the tail part of the boiler. The utility model comprises a pressure port, wherein the pressure port is provided with a fire observation hole; the pressure port is movably connected with a flange sleeve which is fixed on the tail part of the boiler; the pressure port is connected with a circular pad; a compressed spring for propping the pressure port against the tail part of the boiler is installed between the circular pad and the pressure port. The beneficial effects of the utility model are as follows: the structure is simple; the utility model is convenient to use, and can open and close automatically.
Description
Technical field
The utility model belongs to the heating equipment field, relates to a kind of explosion proof door, relates in particular to a kind of spring boiler explosion proof door.
Background technology
At present, most horizontal fuel vapor boiler tail only is equipped with inspection door, and it only provides the effect of inspection and observation flame to boiler as inspection door, but can not solve the problem of boiler in igniting or pressure in the burner hearth in service rising.
Summary of the invention
The utility model will solve the problem that there is pressure release in existing horizontal fuel vapor boiler, and a kind of spring boiler explosion proof door of pressure release voluntarily is provided.
The technical scheme that the utility model adopts is:
Spring boiler explosion proof door, it is installed in boiler tail, it is characterized in that: comprise pressure port, on the said pressure port flame-observing hole is housed; Said pressure port is connected flange movably and puts, and said flange cover is fixed on boiler tail; Be connected with the ring pad on the said pressure port, be equipped with between said ring pad and the pressure port the compression spring of pressure port roof pressure at boiler tail.
The sealing device of labyrinth type further, is installed between said flange cover and the pressure port.
Further, said flange cover around be surrounded by alumina silicate fibre and concrete block.
The described spring boiler of the utility model explosion proof door is a kind of explosion proof door of open-close type voluntarily under the effect of compression spring.Pressure port always is in air-tight state under the effect of compression spring when boiler normally moves, and when backing down pressure port pressure release voluntarily during superpressure in the boiler stove, pressure is got back to sealing state again after descending voluntarily.And have flame-observing hole on the pressure port, and make the described boiler explosion proof door of the utility model can serve as inspection door, can carry out pressure release voluntarily to boiler again.
The beneficial effect of the utility model: simple in structure, easy to use, and can open and close voluntarily.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side view of the utility model.
The specific embodiment
Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these specific embodiment.One skilled in the art would recognize that the utility model contained in claims scope all alternatives, improvement project and the equivalents that possibly comprise.
Referring to Fig. 1, Fig. 2, spring boiler explosion proof door, it is installed in boiler tail, comprises pressure port 5, on the said pressure port 5 flame-observing hole 3 is housed; Said pressure port 5 is connected on the flange cover 1 movably, and said flange cover 1 is fixed on boiler tail; Be connected with ring pad 4 on the said pressure port 5, be equipped with between said ring pad 4 and the pressure port 5 the compression spring 2 of pressure port 5 roof pressures at boiler tail.
The sealing device 6 of labyrinth type is installed between said flange cover 1 and the pressure port 5.
Be surrounded by alumina silicate fibre and concrete block 7 around the said flange cover 1.
The described spring boiler of the utility model explosion proof door is a kind of explosion proof door of open-close type voluntarily under the effect of compression spring 2.Pressure port 5 always is in air-tight state under the effect of compression spring 2 when boiler normally moves, and when backing down pressure port 5 pressure release voluntarily during superpressure in the boiler stove, pressure is got back to sealing state again after descending voluntarily.And have flame-observing hole 3 on the pressure port 5, and make the described boiler explosion proof door of the utility model can serve as inspection door, can carry out pressure release voluntarily to boiler again.
