Abstract
The utility model discloses a spring gravity type anti-explosive door for boiler, wherein it is installed on the tail part of the boiler. The utility model comprises an anti-explosive door, an observation hole and a flange plate, wherein the anti-explosive door and the observation hole are all installed on the flange plate; the flange plate is fixed on a sleeve installed on the tail part of the boiler; the exit of the anti-explosive door is arranged in inclined way; the outer part of the anti-explosive door is covered with an anti-explosive door protection cover; the outer surface of the anti-explosive door is connected with one end of the compressed spring which presses the outer surface of the anti-explosive door; the other end of the compressed spring is fixedly connected with the anti-explosive door protection cover. The beneficial effects of the utility model are as follows: the structure of the utility model is simple; the utility model is convenient to use, and can open and close automatically; the utility model has a long service life and a good sealing effect.
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 gravity type boiler explosion proof door.
Background technology
At present, boiler gravity type explosion proof door all only only relies on the explosion proof door own wt to seal mostly, and such sealing effectiveness is not very desirable, and the service life of explosion proof door is not high.
Summary of the invention
The utility model will solve existing gravity type explosion proof door and have the problem that service life is short, sealing effectiveness is bad, and the spring gravity type boiler explosion proof door of a kind of long service life, good sealing effect is provided.
The technical scheme that the utility model adopts is:
Spring gravity type boiler explosion proof door, it is installed in boiler tail, comprises explosion proof door, peep hole, flanged plate, and said explosion proof door and peep hole are installed on the flanged plate, and said flanged plate is fixed on the sleeve that is installed in boiler tail; The outlet of said explosion proof door is inclined to set; It is characterized in that: the outer cup of said explosion proof door is provided with the explosion proof door protective cover; The outer surface of said explosion proof door is connected with an end of the compression spring that it is pressed, and the other end of said compression spring is fixedly connected with the explosion proof door protective cover.
Further, the outlet of said explosion proof door is 60 ° of settings that are inclined upwardly.
Further, heat-insulation material is filled up in said sleeve inboard.
Further, said flanged plate is to be welded on the said sleeve.
Further, said flanged plate is provided with handle.
The described spring gravity type of the utility model boiler explosion proof door is at the effect lower seal effective boiler explosion proof door of self gravitation with the compression spring.Boiler explosion proof door moment under the effect of self gravitation and spring when normal operation is in sealing state, carries out pressure release when backing down explosion proof door during superpressure in the boiler stove, gets back to sealing state again after the pressure decline.
The beneficial effect of the utility model: simple in structure, easy to use, and keying voluntarily, long service life, good sealing effect.
