Abstract

The utility model discloses a boiler uptake door seal structure, including smoke box body, smoke box door, characterized by, be equipped with first steel bay around the smoke box door the first sealing washer of embedding in the first steel bay, relatively, the smoke box body is equipped with the second steel bay the same or close with first sealing washer shape and imbeds the second sealing washer. Form dual -seal structure, it is sealed effectual.

Description

A kind of boiler uptake door sealing structure
Technical field
This utility model is related to a kind of sealing structure, especially the double-layer sealing structure of boiler smoke chamber door.
Background technology
Boiler seal is to prevent flue gas and extraneous air in burner hearth, flue from mutually leaking from the non-designated position of boiler Structure.For example, in use, the quality of smoke box door sealing effectiveness is most important for WNS types oil-burning gas-fired boiler.Smoke box door If sealing effectiveness difference, Lou cigarette and air intake can be caused, cause heat-energy losses, reduce the thermal efficiency of boiler, have influence on boiler expection Design effect, the straight normal operation for causing to affect boiler.
The content of the invention
This utility model provides a kind of boiler uptake door sealing structure.
The technical scheme that enforcement this utility model is adopted is, including smoke box body, smoke box door, it is characterized in that, the cigarette The first steel tank is provided with around chamber door, the first sealing ring is embedded in first steel tank;Relatively, it is provided with and in smoke box body The second same or like steel tank of one sealing loop-shaped and embedded second sealing ring.
Further, the cross sectional shape of the sealing ring is square or circular or ellipse.
The beneficial effects of the utility model are that when smoke box door is closed, such as after being tightened with bolt, the steel ring of smoke box door holds out against On the sealing ring of smoke box body;Accordingly, the steel ring of smoke box body is held out against on the sealing ring of smoke box door.So, smoke box door Two-layer sealing structure, referred to as double sealing structure are formed, if a sealing ring failure, also another sealing ring is acted as With formation double-layer sealing structure.
Description of the drawings
Fig. 1 is smoke box, smoke box door schematic diagram.
Fig. 2 is the B-B cross-sectional views of Fig. 1.
Fig. 3 is the schematic shapes of steel tank, sealing ring.
Specific embodiment
Referring to Fig. 1, Fig. 2, included by the double dot dash line in wherein Fig. 2 is the part of smoke box door 1.It is embedded in around smoke box door 1 The embodiment band steel circle 3a of steel tank, afterwards, includes a sealing ring 2a;Equally, also have on smoke box body 4 a sealing ring 2b and One band steel circle 3b.
Referring to Fig. 3, when smoke box door 1 is closed, after bolt is tightened, the band steel circle 3a of smoke box door 1 is held out against in the close of smoke box body 4 On seal 2b;Accordingly, the band steel circle 3b of smoke box body 4 is held out against on the sealing ring 2a of smoke box door 1.Sealing ring cross sectional dimensions For 20 × 20mm.So, two-layer sealing structure, referred to as double sealing structure are defined.A sealing ring failure is calculated, also separately One sealing ring works, and forms double-layer safety.After this kind of sealing structure, the oil-burning gas-fired boiler of applicant does not substantially have There is the phenomenon of leakage cigarette.
The present embodiment is a kind of double sealing structure of WNS type oil-burning gas-fired boiler smoke box doors, including using sealing shown in Fig. 3 The shape of circle.But this is not only limited to, can be other shapes.Sealing ring cross section can be square, or Rectangle, can also be the shapes such as circle or ellipse.

Claims (2)

1. a kind of boiler uptake door sealing structure, including smoke box body, smoke box door, is characterized in that, be provided with around the smoke box door First steel tank, is embedded in the first sealing ring in first steel tank;Relatively, smoke box body is provided with and the first sealing loop-shaped phase Same or the second close steel tank and embedded second sealing ring.
2. a kind of boiler uptake door sealing structure as claimed in claim 1, is characterized in that, the cross sectional shape of the sealing ring is Square or circular or ellipse.
