Abstract
The utility model relates to the improvement of a screw sealing joint, particularly an anti-turning screw sealing joint. A rectangle boss is additionally arranged between the sealing end and the screw threads of the screw sealing joint to position the screw sealing joint and prevent the screw sealing joint from turning. The anti-turning screw sealing joint does not turn when the anti-turning screw sealing joint is assembled and disassembled. The anti-turning screw sealing joint can be assembled and disassembled only by one spanner, which is simple.
Description
The utility model relates to the improvement to a kind of seal of vessel joint.
Usually the canister SEALING FITTING all uses welding or screw thread even to press, and container deformation can occur with welding; Destroy the container resin layer; Often turning SEALING FITTING rotates easily.
The purpose of this utility model is to provide a kind of anti-rotation thread seal joint, in use can avoid SEALING FITTING to rotate, and is convenient to tighten; Unscrew.
In conjunction with the accompanying drawings 1, Fig. 2 the utility model is to realize like this, make the nut of hex head bolt into flat garden shape seal boss 2, on container body 7, beat square hole with anti-rotation boss 1 same size of anti-rotation thread seal track bolt 5, it is coincide mutually, seal washer 6 is enclosed within on the anti-rotation SEALING FITTING bolt 5, and is inserted in the square hole of container body 7.The standard nut size is strengthened, and add greater than square anti-rotation boss 1 Diagonal Dimension,, form trough of belt flat nut 8 less than the garden circular groove 4 of garden shape seal boss 2 diameter dimensions in the inboard.Tighten with trough of belt flat nut 8 and anti-rotation thread seal track bolt 5, the garden circular groove 4 of trough of belt flat nut 8 wherein, in rundown process, can avoid interference with anti-rotation boss 1, and the square hole of anti-rotation boss 1 and container body 7 is engaged in when tightening and does not rotate, make fastening reliable that anti-rotation thread seal track bolt 5, seal washer 6, container body 7, trough of belt flat nut 8 twist, sealability is better, and plug screw 9 or other link are connected with attachment hole 3, can finish various uses.
The anti-rotation thread seal joint of making according to said structure.Rotate when having avoided tightening, inconvenient shortcoming is installed, as long as can install with a spanner, and it is reliable to be tightly connected.
Description of drawings:
Fig. 1 anti-rotation thread seal joint connecting structure schematic representation
Fig. 2 anti-rotation thread seal track bolt plan view
Fig. 3 anti-rotation thread seal track bolt plan view
Fig. 4 trough of belt flat nut plan view
Fig. 5 trough of belt flat nut plan view
Embodiment as: according to structure shown in the accompanying drawing, according to the requirement of different purposes, can design each spot size of anti-rotation thread seal joint arbitrarily, material therefor can select No. 20 or No. 35 steel etc. according to different purposes.
When using, as long as the container body desired area is got through the square hole that matches with anti-rotation thread seal track bolt, the structure installation of pressing Fig. 1 gets final product.
Claims (1)
