Abstract
The utility model discloses a vacuum safety dead weight device, including groove flange and the apron of cover on the groove flange, be provided with the annular groove on the groove flange, be provided with the sealing washer between groove flange and the apron, the sealing washer sets up in the annular groove. The technical scheme of the utility model with sealing washer replacement rupture disk commonly used, the cost has been practiced thrift.
Description
Technical field
The utility model relates to a kind of safety device of boiler, is specifically related to a kind of vacuum safety self-weight device.
Background technology
Vacuum boiler on the market often requires that furnace pressure is less than ambient pressure, in order to ensure that furnace pressure is less than ambient pressure, usual employing rupture disk is as safety device, rupture disk explosion under the temperature and pressure of regulation, relieving pressure, prevents vacuum boiler from destroying because furnace pressure is excessive and even explodes.
But the price of rupture disk is higher, and easily explosion, just can not re-use once explosion, need manually to change, virtually improve the cost of boiler operatiopn.
Utility model content
For solving the problem, the utility model provides a kind of cheap vacuum safety self-weight device.
In order to realize above object, the utility model adopts following technical scheme: a kind of vacuum safety self-weight device, comprises groove flange and covers the cover plate on groove flange; Groove flange is provided with annular groove; Sealing ring is provided with between described groove flange and cover plate; Sealing ring is arranged in annular groove.By the gravity-pressing sealing ring of cover plate, reach the effect of sealing, when the pressure in vacuum boiler is greater than external atmospheric pressure, cover plate can by jack-up, and the pressure in boiler can be discharged, and avoids vacuum boiler to destroy because furnace pressure is excessive and even explodes.The technical solution of the utility model sealing ring replaces conventional rupture disk, has saved cost.
The thickness of described sealing ring is greater than the degree of depth of annular groove.Prevent there is space between sealing ring and the upper plane of groove flange; Reach the effect that sealing is tight.
Described groove flange is connected with nut by studs with cover plate.Prevent transportation cover plate drop; Prevent when the pressure in vacuum boiler is greater than ambient atmosphere pressure, cover plate is flown by interior bearing down on one simultaneously, damages peripheral facilities or personnel; When the pressure in vacuum boiler arrives after in safe range, cover plate can automatic landing, again covers on groove flange, without the need to manual operation, and saving manpower.
The technical solution of the utility model has cost-saving, labor-saving advantage.

Fig. 1 is the top view of the groove flange of a kind of vacuum safety self-weight device that the utility model embodiment provides;
Fig. 2 is the side sectional view of a kind of vacuum safety self-weight device that the utility model embodiment provides.
Detailed description of the invention
Embodiment
See shown in Fig. 1-2, a kind of vacuum safety self-weight device that the present embodiment provides, the cover plate 3 comprising groove flange 5 and cover on groove flange 5; Groove flange 5 is provided with annular groove 1; Sealing ring 6 is provided with between described groove flange 5 and cover plate 3; Sealing ring 6 is arranged in annular groove 1.By the gravity-pressing sealing ring 6 of cover plate 3, reach the effect of sealing, when the pressure in vacuum boiler is greater than external atmospheric pressure, cover plate 3 can by the gas jack-up discharged from blast pipe 7, pressure in boiler can be discharged, and avoids vacuum boiler to destroy because furnace pressure is excessive and even explodes.The technical solution of the utility model sealing ring 6 replaces conventional rupture disk, has saved cost.
The thickness of described sealing ring 6 is greater than the degree of depth of annular groove 1.Prevent there is space between sealing ring 6 and the upper plane of groove flange 5; Reach the effect that sealing is tight.
Described groove flange 5 is connected with nut 2 by studs 4 with cover plate 3.Prevent transportation cover plate 3 drop; Prevent when the pressure in vacuum boiler is greater than ambient atmosphere pressure, cover plate 3 is flown by interior bearing down on one simultaneously, damages peripheral facilities or personnel; When the pressure in vacuum boiler arrives after in safe range, the automatic landing of cover plate 3 meeting, covers again on groove flange 5, without the need to manual operation, saves manpower.
The technical solution of the utility model under the premise that security is guaranteed can also be obviously cost-saving.
