Abstract
The utility model belongs to the boiler field, in particular to boiler coal gas safety explosion-proof valve. The explosion-proof valve is provided with a valve body, a lifting seal cover and a lifting column; and the lifting seal cover is arranged on the upper part of the valve body, and the lifting column penetrates through a central opening of the lifting seal cover. A fixing plate is mounted in the valve body and a central slide hole is arranged in the center of the fixing plate; one end of the lifting column passes through the slide hole of the fixing plate to extent out of the lifting seal cover, fastening screws are mounted on the lifting column and on both sides of the lifting seal cover, and the other end of the lifting column is provided with a limit retainer. The boiler coal gas safety explosion-proof valve is mounted on the top of the boiler, the lifting seal cover is arranged on the upper part of the valve body, the lifting seal cover can ascend and descend according to the internal pressure of the boiler, so as to open or close the valve body, and the automatic adjustment of the internal pressure of the boiler is accordingly realized.
Description
Technical field
The utility model belongs to field of boilers, is specially a kind of boiler coal gas safety anti-explosive valve.
Background technique
At present, China's steam generation boiler development is very fast, but the boiler coal gas explosion is a critical problem, and boiler coal gas explosion-proof performance is relatively poor in the prior art.
The model utility content
Problems such as the purpose of this utility model is to provide a kind of boiler coal gas safety anti-explosive valve, and the boiler coal gas explosion-proof performance that exists in the solution prior art is relatively poor.
The technical solution of the utility model is:
A kind of boiler coal gas safety anti-explosive valve, this explosion-proof valve is provided with valve body, lifting sealing cover, lifting rod, establishes the lifting sealing cover on valve body top, and the center drilling place of lifting sealing cover is equipped with lifting rod.
Described boiler coal gas safety anti-explosive valve, mounting plate in valve body is established sliding eye at the center of fixed plate; The sliding eye that one end of lifting rod passes fixed plate stretches out the lifting sealing cover, fastening screw is installed in the both sides of lifting sealing cover on the lifting rod.
Described boiler coal gas safety anti-explosive valve, the other end of lifting rod is provided with limiting block.
The beneficial effects of the utility model are:
The utility model boiler coal gas safety anti-explosive valve is installed on the top of boiler by valve body, establishes the lifting sealing cover on valve body top, and the lifting sealing cover can make valve body open or close according to the lifting of boiler internal pressure, realizes the automatic adjusting of boiler internal pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2-3 is the structural representation of valve body among Fig. 1.Wherein, Fig. 2 is a plan view; Fig. 3 is a plan view.
Fig. 4 is the structural representation of lifting sealing cover and lifting rod among Fig. 1.
Fig. 5 is the plan view of lifting sealing cover among Fig. 1.
Among the figure, 1 lifting sealing cover; 2 fastening screws; 3 lifting rods; 4 valve bodies; 5 limiting blocks; 6 fixed plates; 7 boilers; 8 sliding eyes.
Embodiment
Shown in Fig. 1-5, the utility model boiler coal gas safety anti-explosive valve mainly comprises: lifting sealing cover 1, fastening screw 2, lifting rod 3, valve body 4, limiting block 5, fixed plate 6, sliding eye 8 etc.,
Valve body 4 is installed at top at boiler 7, and mounting plate 6 in valve body 4, establish sliding eye 8 (Fig. 2-3) at the center of fixed plate 6; Establish lifting sealing cover 1 on valve body 4 tops, the center drilling place of lifting sealing cover 1 is equipped with lifting rod 3, and the sliding eye 8 that an end of lifting rod 3 passes fixed plate 6 stretches out lifting sealing cover 1, fastening screw 2 is installed in the both sides of lifting sealing cover 1 on the lifting rod 3.The other end of lifting rod 3 is provided with limiting block 5, lifting rod 3 rise to certain altitude the time, the plate 6 that can be fixed blocks, and prevents that lifting rod 3 from continuing raise (Fig. 4-5).
In the utility model, leave the gap between lifting rod 3 and the sliding eye 8, lifting rod 3 can slide along sliding eye 8.
The working procedure of present embodiment is as follows:
As shown in Figure 1, during proper functioning, the lifting sealing cover 1 and the valve body 4 of boiler coal gas safety anti-explosive valve are in closed state.When the pressure in the boiler 7 was higher, the boiler internal pressure acted on lifting sealing cover 1, and lifting sealing cover 1 drives sliding eye 8 risings of lifting rod 3 along fixed plate 6 centers, and flue gas is discharged by the gap between lifting rod 3 and the sliding eye 8, and boiler 7 internal pressures are reduced.After the pressure in the boiler 7 reached requirement, lifting sealing cover 1 dropped to and valve body 4 sealings by gravity, realizes regulating automatically the boiler internal pressure.
