Embodiment Construction

[0012] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0013] The double-sealed groove tee shell support assembly shown in the attached figure includes support flange 4.1 and support 4.2; one end of support 4.2 is flanged to form support flange 4.1, namely support 4.2 and support flange 4.1 for an integrated structure.

[0014] The outer end surface of the flange 4.1 of the support tube is provided with an outer sealing groove II 4.4 and an inner sealing groove II 4.3 which are coaxially fitted and have the same groove width; the depth of the outer sealing groove II 4.4 is smaller than that of the inner sealing groove II 4.3 depth.

Abstract

The invention discloses a support cylinder assembly with two sealing grooves for a three-way shell. The support cylinder assembly comprises a support cylinder flange and a support cylinder, wherein one end of the support cylinder is turned up to form a support cylinder flange, namely the support cylinder and the support cylinder flange are of an integrated structure; further improvement is that anouter sealing groove II and an inner sealing groove II which are coaxially sheathed and have the same groove width are arranged on the end face, facing outwards, of the support cylinder flange; and the depth of the outer sealing groove II is smaller than the depth of the inner sealing groove II. According to the support cylinder assembly, no welding stress exists, so that welding deformation is avoided, and furthermore, the structural strength is high, and the sealing effect is good.

Description

technical field [0001] The invention relates to the field of high-voltage substations, in particular to a cable tee shell support sleeve assembly. Background technique [0002] A support tube assembly is provided on the side of the cable tee housing, and the support tube assembly includes a support tube flange and a support tube. The main defect of this support tube assembly is that the support tube and the support tube flange are welded and assembled, the welding stress is large, and the welding deformation is large. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the utility model proposes a double-sealed-groove tee shell support assembly that can significantly reduce deformation. [0004] The present invention achieves technical goals through the following technical solutions. [0005] Double seal groove tee housing support assembly, including support flange and support; the improvement is that: one end of the support is flanged to form...
