Abstract
The utility model relates to a compound straight joint of stainless steel, include: connect the body, shown joint body both ends are equipped with holds the mouth of a river, connect this internal two passageways that hold the mouth of a river of intercommunication that are equipped with, connect this internal holding ring that is equipped with, the holding ring is stainless steel. The utility model discloses a can not appear when the holding ring that connects this internal design stainless steel makes tubular product connect in the hot melt plastics clamp -on tubular product, the difficult production is precipitated, is difficult for multiplying the bacterium, and the water delivery is unobstructed, low in production cost.
Description
Technical field
The present invention relates to running water pipe link technical field, especially relate to a kind of stainless steel composite straight joint.
Background technique
In prior art, pipe joint is the main connector element in pipework, current pipe joint has the pipe joint two kinds of metal material and plastic material, wherein joint for plastic tube realizes the location of two stainless steel composite water pipes by forming protruding plastics positioning ring in pipe joint, and then carry out sweat soldering, during sweat soldering, the tube wall that the yielding generation of plastics positioning ring is coarse, tube wall easily produces precipitation, breed bacteria, affect water delivery, and arrange screw member at pipe joint and stainless steel composite water pipe two ends, its cost of production is high.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stainless steel composite straight joint.
The utility model solves the technological scheme that its technical problem adopts: a kind of stainless steel composite straight joint, comprise: joint body, shown joint body two ends are provided with holds the mouth of a river, the passage that the mouth of a river is held in connection two is provided with in described joint body, be provided with positioning ring in joint body, described positioning ring is stainless steel.
Positioning ring by designing stainless steel in joint body in above-mentioned design makes tubing there will not be hot melting plastic to clamp-on in tubing when connecting, and not easily produce precipitation, not easily breed bacteria, water delivery is unobstructed, and cost of production is low.
As the further improvement of the design, described positioning ring height is identical with external tubing total thickness, and described positioning ring is ring-type, and stainless steel materials are few, cost-saving.
As the further improvement of the design, the Stainless Steel Tube be connected with described positioning ring internal diameter is provided with in described passage, external diameter and the described vias inner walls of described Stainless Steel Tube are provided with the holding cavity holding external tubing wall, and when namely described joint body is connected with tubing, described Stainless Steel Tube inserts and connects in tubing.By Stainless Steel Tube is inserted tubing inside, improve the join strength of tubing and joint body.
As the further improvement of the design, described Stainless Steel Tube two ends inwall is provided with chamfering.Described chamfering makes tubing inner smooth-going with Stainless Steel Tube transition, reduces bacteria breed.
As the further improvement of the design, be provided with the Stainless Steel Tube be connected with described positioning ring external diameter in described passage, described positioning ring internal diameter and described Stainless Steel Tube internal diameter distance are the stainless steel lining thickness of external tubing.Reduce stainless steel consumption and can join strength be increased, preventing plastics from clamp-oning in tubing.
As the further improvement of the design, be provided with plastic hoop in the passage of described joint body, described positioning ring is connected with the internal diameter of described plastic hoop.
As the further improvement of the design, described plastic hoop thickness and Stainless Steel Tube thickness sum equal the plastic layer of external tubing.
The beneficial effects of the utility model are: the utility model makes tubing there will not be hot melting plastic to clamp-on in tubing when connecting by the positioning ring designing stainless steel in joint body, not easily produce precipitation, not easily breed bacteria, water delivery is unobstructed, and cost of production is low.
