Connection pipe fitting connection at present is insecure, shortcomings such as poor sealing performance.
The model utility content
The utility model purpose aims to provide a kind of interior direct connection pipe fitting of tooth of stainless steel of stamped, and this stainless steel connection pipe fitting is connected firmly good airproof performance.
For achieving the above object, the technical solution adopted in the utility model is: the direct connection pipe fitting of tooth in a kind of stainless steel of stamped, comprise body, flanged plate and seal ring, described flanged plate is inserted in body, described ring set on body, seal ring supported flange plate, described connection pipe fitting is set to the interior direct connection pipe fitting of tooth, the two ends connection pipe fitting directly is connected to each other, and described two ends connection pipe fitting interconnects, the direct part of tooth in being provided with between the connection pipe fitting of described two ends.
The direct connection pipe fitting of tooth in the stainless steel of described a kind of stamped, its flanged plate one end are provided with joint socket in the lower flange.
The direct connection pipe fitting of tooth in the stainless steel of described a kind of stamped, its connection pipe fitting one end is provided with the pipe bell end.
The direct connection pipe fitting of tooth in the stainless steel of described a kind of stamped, its flanged plate fixing device is a nut.
The method of making this stainless steel connection pipe fitting is:
Step 1: get a stainless-steel pipe, size is cut out pipe according to the rules.
Step 2: will cut out good stainless-steel pipe and be put on the peculiar fixed mould, stainless-steel pipe is fixed.
Step 3: the stainless-steel pipe that fixes on peculiar fixed mould is at specific special device extrusion moulding.
Step 4: again to the stainless-steel pipe deep processing finished product of extrusion moulding.Specifically, be exactly to utilize existing tubular body, force material deformation through peculiar (different specifications) mould and special device, the process of distortion reaches specific shape.
The method advantage of making this stainless steel connection pipe fitting is: shorten manufacturing a finished product the cycle, enhance productivity, reduce toxic emission, environmental protection standard improves; Improve product percent of pass, reduce reject rate; Reduce cost of production, meet the need of market.
The direct connection pipe fitting of tooth can guarantee sealability in this stainless steel, seal ring supported flange plate, make this stainless steel connection pipe fitting sealing effect highly significant, the inwall engaging surface that connection pipe fitting is close in the seal ring expansion forms flexible sealing, because of sealing material has plasticity, under the external force effect of distortion back, also can keep good sealing effect.
The direct connection pipe fitting of tooth in this stainless steel is because be the direct connection pipe fitting of interior tooth, connects very firmly, and sealing is extraordinary.
