The tee joint stainless steel pipe is applied to pipeline connection of the industry, the construction industry and household water and gas feeding. The tee joint stainless steel pipe comprises a tee joint body, wherein each port of the tee joint body is fixedly connected with a connection pipe, the pipe opening of each connection pipe is provided with an expansion joint protruding outwards, the outer wall of each connection pipe is provided with an anti-skidding abrasion-resistant layer, the tee joint body and the connection pipes are distributed in an integrated mode, and the connection pipes and the expansion joint are distributed in an integrated mode. The tee joint stainless steel pipe high in assembly accuracy is high in structural compactness and convenient to operate, the fastening intensity is improved, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of threeway stainless steel pipe, relates in particular to a kind of threeway stainless steel pipe of high assembly precision, and the pipeline that is applied to industry, building industry, household feedwater, gas connects.
Background technique
The fastening piece connecting at pipeline in prior art, fastening dynamics is relatively not strong, in use, the connection part that often all appears at fastening piece of leakage occurs, and causes unnecessary loss, affects service condition.
In Chinese patent 201020301460.5, disclose a kind of fastening piece with internal and external threads, relate to clamp structure technical field, solved the technical problem that operation is loaded down with trivial details that is connected and fixed of current multi-layer structure object.The utility model comprises bolt shape body, it is characterized in that described body outer wall has outside thread, and centre is provided with the groove of opening at top, and described groove walls has internal thread.This structure relative complex, and fastening strength is relatively low.
Model utility content
The utility model is mainly to solve the deficiencies in the prior art, and a kind of compact structure is provided, and employing stainless steel is raw material, utilizes expansion joint to form screens, and anti-skid wearable layer makes the threeway stainless steel pipe of fastening more firmly high assembly precision simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of threeway stainless steel pipe of high assembly precision, comprise threeway joint body, each interface and the connecting tube of described threeway joint body are fixedly connected, the mouth of pipe place of described connecting tube is provided with outwards outstanding expansion joint, the outer wall of described connecting tube is provided with anti-skid wearable layer, described threeway joint body and connecting tube are integrated distribution, and described connecting tube and expansion joint are integrated distribution.
As preferably, between described threeway joint body and connecting tube, be connected by changeover portion, the cross section of described changeover portion is trapezoid shaped.
As preferably, the two side ends of described expansion joint is connected by the transition of arcuate segment phase respectively with connecting tube, and the diameter of described expansion joint is greater than the diameter of connecting tube.
As preferably, described threeway joint body, connecting tube and expansion joint are respectively stainless steel pipe.
Utilize the pipeline of this structure to connect, there is good stability, be connected and fixed intensity high.Anti-skid wearable layer refers to that surface is not smooth plane.
The threeway stainless steel pipe of the high assembly precision that the utility model provides, compact structure degree is high, easy to operate, improves fastening strength, improves working life.
