Abstract
A gas seal apparatus characterized by: comprises a sealing air box 1, a reinforcing device 2, a sealing rubber ring 3, a sealing cover plate 4, a spring washer 5 and a bolt 6; wherein, the reinforcing device 2 is connected with the sealing air box 1, and the sealing cover plate 4 is connected with the reinforcing device 2 through a spring washer 5 and a bolt 6. The utility model changes the traditional structure and improves the performance; can be applied to gas-enclosed switchgear.
Description
Technical field
The utility model relates to mechanical field, and a kind of gas-tight sealing is provided especially.
Background technique
Along with the continuous development of power industry, the application of various novel switching devices is general enclose more and more wider.Particularly gas-insulated enclosed switch equipment is more and more used in recent years, and the technological requirement of gas-filled type switch cubicle progressively improves, and traditional gas-tight sealing demonstrates its defective on processes.At present, the seal arrangement that general gas sealing switch equipment adopts, welding screw on seal case is pressed on the O-ring seal with cover plate during sealing, fastening nut on welding screw, cover plate compresses seal ring, thereby reaches seal request.The shortcoming of this processing method is, because the stud welding bonding area is little, when gland nut, the double-screw bolt obscission takes place sometimes, cause sealing effect undesirable, simultaneously, because double-screw bolt is a bit stressed when gland nut, lifting surface area is little, under stress, slight metaboly can take place in the gas tank casing, and the fixed position of close cushion rubber is wayward simultaneously, seal ring can be extruded the phenomenon of cover plate under pressure by the effect of seal lubrication ester.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of gas-tight sealing is provided especially.
The utility model provides a kind of gas-tight sealing, it is characterized in that: include sealing gas tank 1, reinforcing device. 2, O-ring seal 3, sealed cover 4, spring washer 5, bolt 6; Wherein reinforcing device. 2 is connected with sealing gas tank 1, and sealed cover 4 is connected with reinforcing device. 2 by spring washer 5, bolt 6.
Described gas-tight sealing, reinforcing device. 2 are welded on the inflation casing 1, and top processing compresses O-ring seal 3 and uses tapped hole.
Described gas-tight sealing, O-ring seal 3 are installed in reinforcing device. 2 inside.
It is a kind of simple in structure that the utility model provides, and function admirable is processed the requirement that simple gas-tight sealing adapts to gas-insulated enclosed switch equipment; For achieving the above object, the technical solution of the utility model provides a kind of gas-tight sealing, reinforcing device. 2 is welded on the sealing gas tank 1, play the effect that sealing gas tank 1 is reinforced, simultaneously be again bolt 6 when compressing screw connection and the limit stoper of O-ring seal 3, because reinforcing device. 2 bonding areas are bigger, the easier firm welding that reaches on welding procedure, the stress dispersion of casing to Bolt Connection inflated in the simple requirement of welding method simultaneously, and the gas tank casing is not yielding, guarantee higher tightness, improve the insulating property of switching device, reduced the generation of gas leakage phenomenon, reduced operation troubles rate and maintenance cost.
Advantage of the present utility model: processing technology is simple, and processing cost is low, improves the switching device tightness, reduces the operation troubles rate and the maintenance cost of equipment.
