Abstract
The utility model relates to the technical field of boiler inner sealing structures, in particular to a boiler maim steam ERV valve outlet sealing structure. The boiler maim steam ERV valve outlet sealing structure has the advantages that the sealing effect is better, the sealing intensity is increased, and the utilization rate of equipment is improved, and comprises a valve body and an end cover, wherein through holes are formed in the valve body and the end cover; the through hole in the valve body is communicated with the through hole in the end cover; the valve body and the end cover are mounted together. The boiler maim steam ERV valve outlet sealing structure also comprises a metal octagonal cushion and a metal winding cushion; a first placing cavity and a second placing cavity are formed in the connecting part of the valve body and the end cover; the metal octagonal cushion is located in the first placing cavity; the metal winding cushion is located in the second placing cavity.
Description
Technical field
The utility model relates to the technical field of boiler inner seal structure, particularly relates to a kind of boiler main vapour ERV valve outlet port sealing configuration.
Background technique
As everyone knows, ERV valve is exactly the pneumatic ball valve by electromagnetic valve, its effect is to move before mechanical spring safety door action prerequisite, protection spring safety door (the spring safety door fragile leakage vapour that acts frequently, and after leakage vapour, can not completely cut off), the height that is depended on pressure switch or contact definite value is controlled, while not moving higher than operating pressure as pressure in service, can manually opened pressure release, avoid pressure-containing member superpressure to adopt ball valve form at existing like product ERV valve, flange face sealing between outlet end cap and valve body adopts metal octangonal ring and the tight power of bolt to seal, after valve installation completes, the gap of flanged surface is zero, therefore, if occur, metal octangonal ring installs incorrect or octangonal ring and washes away damage, will cause flange facing steam to leak outside, and has a strong impact on steam parameter and the personal safety of unit, makes the reliability decrease of unit, and Utilization ratio reduces, and sealing effect is poor.
Model utility content
For solving the problems of the technologies described above, the utility model provides the boiler main vapour ERV valve outlet port sealing configuration that a kind of sealing effect is better, increase sealing intensity, raising Utilization ratio.
Boiler main vapour ERV valve outlet port sealing configuration of the present utility model, comprises valve body and end cap, and the inside of valve body and the inside of end cap are provided with through hole, and the through hole of valve inner communicates with the through hole of end cap inside, and described valve body and end cap are installed together; Also comprise metal octangonal ring and metal wound gasket, the joint of described valve body and end cap is provided with the first placed cavity and the second placed cavity, and described metal octangonal ring is positioned at the first placed cavity, and described metal wound gasket is positioned at the second placed cavity.
Boiler main vapour ERV valve outlet port sealing configuration of the present utility model, together with the top of described valve body is all bolted to by valve body with and the bottom of valve body and the bottom of end cap, the top of end cap.
Boiler main vapour ERV valve outlet port sealing configuration of the present utility model, described the first placed cavity and the second placed cavity are all positioned on end cap.
Boiler main vapour ERV valve outlet port sealing configuration of the present utility model, the thickness of described metal wound gasket is 2.2mm.
Compared with prior art the beneficial effects of the utility model are: by above-mentioned setting, can reach the good object of sealing effect by the double seal effect of metal octangonal ring and metal wound gasket, increase sealing intensity, improve Utilization ratio.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
