Abstract
The utility model discloses a boiler with an explosion-proof fire observation device, which comprise a boiler body, wherein a pressure-relief hole is formed at the tail part of the boiler body, a flange plate is arranged at the outer end of the pressure-relief hole, the outer end of the flange plate is connected with the tail of the boiler body by a bolt, and a cover is arranged on the flange plate. A sealing ring is arranged between the flange plate and the cover, a round pipe protrudes out from the middle part, a fire observation wind is arranged at the end part of the round pipe, and the outer end of the cover is sleeved on a guide rod, the guide rod is sleeved with a compression spring, the compression spring presses the cover, one end of the guide rod is connected with the flange plate, and the other end of the flange plate is connected with a fixing plate. According to the boiler, an explosion door and a fire observation device are integrated together, on the basis of not changing the structure of pressure bearing elements of the boiler, the safety requirement is met, and meanwhile, the need for observing flame can be met. The boiler has the advantages of simple structure and high integration.
Description
Technical field
The utility model relates to a kind of boiler, is specifically related to the fiery device of explosion-proof sight of boiler.
Background technology
Present stage, the explosion proof door of boiler was two independently parts with seeing fiery device, on the furnace wall, need open two holes, and need seal respectively each hole, increased the corresponding difficulty of boiler seal aspect, increased manufacturing cost in the boiler for producing process.Therefore, the inventor improves explosion proof door and the fiery device of sight, with both functional unifications, has reduced the difficulty of boiler seal, has saved manufacturing cost.
The utility model content
The purpose of the utility model is to provide a kind of boiler with the fiery device of explosion-proof sight, and this boiler structure is novel, its explosion proof door and the fiery device functional unification of sight, and boiler is easy to use.
The utility model to achieve these goals, the technical solution of employing is:
Have the boiler of the fiery device of explosion-proof sight, comprise body of heater, have relief hole on the body of heater afterbody; The outer end of relief hole is provided with ring flange, and ring flange is provided with lid, and pipe is stretched out at the middle part of lid; The end of pipe is provided with sees fiery window; Said lid outer end is enclosed within on the guide post, and guide post is with the compression spring, and the compression spring is being pressed lid.
Above-mentioned guide post one end is connected with ring flange, and the other end is connected with fixed head.
Be provided with sealing ring between above-mentioned ring flange and the lid.
Above-mentioned ring flange outer end is connected with the body of heater afterbody by bolt.
The beneficial effect of the utility model:
This kind boiler integrates explosion proof door and the fiery device of sight, on the basis that does not change boiler pressure-containing member structure, has satisfied security needs, has also satisfied the needs of observing flame simultaneously.Have simple in structure, integrated high advantage.
When the body of heater internal pressure was in normal range (NR), the compression spring was pressed on lid on the ring flange, has guaranteed the boiler good sealing property.When body of heater internal pressure overrun higher limit, pressure is pushed lid open, makes between lid and the ring flange space to occur; Inner flue gas of the stove is discharged from the space; Reach the purpose that reduces furnace pressure, when furnace pressure was got back to normal range (NR), the compression spring was pressed on lid on the ring flange.
Description of drawings
Fig. 1 is the partial structurtes sketch map with the fiery device boiler of explosion-proof sight.
The specific embodiment
In conjunction with Fig. 1 the utility model is elaborated:
Boiler with the fiery device of explosion-proof sight comprises body of heater 1, has relief hole 2 on body of heater 1 afterbody, and the outer end of relief hole 2 is provided with ring flange 3, and ring flange 3 outer ends are connected with body of heater 1 afterbody by bolt 4, and ring flange 3 is provided with lid 5.Be provided with sealing ring 6 between ring flange 3 and the lid 5; Pipe 7 is stretched out at the middle part of lid 5, and the end of pipe 7 is provided with sees fiery window 8, and said lid 5 outer ends are enclosed within on the guide post 9; Guide post 9 is with compression spring 10; Compression spring 10 is being pressed lid 5, and guide post 9 one ends are connected with ring flange 3, and the other end is connected with fixed head 11.
In the use, when the body of heater internal pressure was in normal range (NR), the compression spring was pressed on lid on the ring flange, has guaranteed the boiler good sealing property.When body of heater internal pressure overrun higher limit, pressure is pushed lid open, makes between lid and the ring flange space to occur; Inner flue gas of the stove is discharged from the space; Reach the purpose that reduces furnace pressure, when furnace pressure was got back to normal range (NR), the compression spring was pressed on lid on the ring flange.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
