Abstract
The utility model discloses a kind of Medium voltage switch or circuit breaker gas tank of turnup structure, it is characterised in that：The flange hole of once punching press flange shaping is set on medium pressure switch gas tank, and the flange hole side is welded with the bolt for installing sealing flange.The utility model Flange gas tank structure, punch forming are integrally formed without welding and solve sealing structure stability, reduce gas tank weld seam, reduce the leak rate of gas tank, lift product reliability, solve axle clamping stagnation caused by welded flange deformation.
Description
Technical field
It the utility model is related to technical field of electric equipment, and in particular to Medium voltage switch or circuit breaker gas tank.
Background technology
With the raising that the development people of society require, the lifting firm in structure of product is also indispensable one.Knot
Solid, safe, the moderate commodity of structure, it is easy to win that client favors.This requires product design personnel to take into account
The requirement of various aspects effectively realizes these mesh to improve quality and reduce cost to the integrated can of parts
's.In European and American developed countries, their matured product realizes the integrated of parts substantially, realizes modularized design, module
Metaplasia is produced.Spare and accessory parts integration degree height can not only reduce part process time, can also reduce assembling complexity, reduce assembling
Time, human cost and time cost are all up effectively reducing, so as to effectively improve the competitiveness of product in market.State
Due to starting late, hysteresis is compared in development, just starts recent years to recognize that parts are integrated right for enterprise in the interior same industry
The importance of product, therefore fast development is able to, start in strategic sight in line with international standards and enhance product
Overall competitive strength.
Gas tank is using welded flange is airtight, supporting construction in present domestic ring main unit product.It is existing to use welded flange
Mode mainly have the disadvantage that：
(1) welded flange requires that machining accuracy is high, and difficulty of processing is big, long processing time, and cost is higher.
(2) in welding process, because temperature height causes flange distortion, planeness of flange deficiency, gas leakage is caused.
(3) gas tank deforms in welding process, causes parallel flange degree insufficient, causes axle catching phenomenon, increases assembly difficulty.
(4) flange easily has stomata with gas tank weld, causes gas leakage.
Utility model content
Based on the deficiencies in the prior art, the purpose of this utility model is the Medium voltage switch or circuit breaker gas for providing a kind of turnup structure
Case, gas tank leak rate is reduced, enhancing gas tank part is integrated, strengthens overall structure stability, makes gas tank more sturdy and durable.
To achieve the above object, the technical solution of the utility model is：
A kind of Medium voltage switch or circuit breaker gas tank of turnup structure, medium pressure, which switchs, sets once punching press flange shaping on gas tank
Flange hole, the flange hole side are welded with the bolt for installing sealing flange.
Further, the aperture of the flange hole is 38mm, and flange height is not less than 15mm.
Further, the height of the vertical component of the flange is not less than 9mm.
Further, the radius of corner R of the flange hole outward flanging is not more than 3mm.
Further, the thickness of the flange material of the flange hole is not less than 2mm.
The beneficial effects of the utility model are：Due to Flange gas tank structure of the present utility model, punch forming need not
Welding, it is integrally formed and solves sealing structure stability, reduce gas tank weld seam, reduce the leak rate of gas tank, lifting product is reliable
Property；Solves axle clamping stagnation caused by welded flange deformation.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the cross-sectional view one of the utility model specific embodiment flange hole；
Fig. 3 is the cross-sectional view two of the utility model specific embodiment flange hole.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, it is impossible to it is considered as being used to limit reality of the present utility model
Apply scope, all equivalent changes made according to the scope of the utility model and improvement etc., based on embodiment of the present utility model, this area
The other embodiment that is obtained on the premise of not paying creative work of technical staff, belong to the utility model protection
Scope.
As shown in Figure 1, Figure 2 and Figure 3, the Medium voltage switch or circuit breaker gas tank of a kind of turnup structure, medium pressure switchs to be set on gas tank 1
The once flange hole 2 of punching press flange shaping, the side of flange hole 2 is welded with the bolt 3 for installing sealing flange.It is described
The aperture D of flange hole 2 is 38mm, and flange height H is not less than 15mm.Manufacturing process can open a small diameter bore in advance, be then punched into
Type back aperture D is 38mm.
The radius of corner R of the outward flanging of flange hole 2 is not more than 3mm, does not interfere with follow-up gas tank surface screw welding
And flange size.Hole flanging height H vertical component length H1, H1 is no less than 9mm, does not influence the stabilization of follow-up axle sleeve installation
Property；The material thickness t1 of flange is no less than 2mm after hole flanging, and bearing minor impact should not deform.
It should be noted that simply preferred embodiment of the present utility model described above, the utility model not office
It is limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, it is new should all belongs to this practicality
The protection domain of type.
