Abstract
The utility model relates to a cutting pipe grafting type branch pipe joint which is formed by a branch pipe joint body, a tightening screw cap, a wedge type locking ring and a sealing ring. In manifold, when a branch pipeline needs to be changed or added, a section of a main pipe is cut through; one end of the branch pipe joint body is obliquely inserted into an end opening of a cut-through fixing pipe, is continued to be placed into the end opening and is placed in the middle in the reverse direction; the screw cap is closely screwed and tightened; a large end plane which is arranged on the wedge type locking ring is wedged into an inner conical surface which is arranged on the branch pipe joint body under the pushing and shoving of a thread bottom end plane which is arranged in the tightening screw cap to enable the opening which is formed on the wedge type locking ring to be closed and the ring diameter is shrunk to clamp the cut-through fixing pipe; a small end plane which is arranged on the wedge type locking ring pushes and shoves the sealing ring at the same time to enable the outer diameter of the sealing ring to be deformed to be closely attached to the inner conical surface which is arranged on the branch pipe joint body and the inner diameter of the sealing ring to be closely against a cylindrical surface of the cut-through fixing pipe; and accordingly the sealing between the branch pipe joint body and the cut-through fixing pipe is achieved. The cutting pipe grafting type branch pipe joint has the advantages of being reasonable in design, good in applicability, strong in flexibility, convenient to graft and low in construction cost, saving labor and time and the like.

Technical field
The utility model relates to a kind of branch pipe connection, and a kind of linkage structure that is used for the branch pipe connection of grafting arm on integrated piping particularly belongs to pipe fitting design and manufacturing technology field.
Background technique
In various water supply, air feed, fire-fighting and other low-pressure manifold, usually because special circumstances need to change or increase water supply, the air feed circuit of arm on fixing main pipe, particularly more there is this to need in the fire fighting supply pipeline.In this case, people adopt the demolition main pipe usually, and the way of loading onto two split supervisors and between two split supervisors, branch pipe connection being installed realizes changing or increasing water supply, the air feed circuit of arm with this.This way difficulty of construction is large, time-consuming, take a lot of work, and even construction can't be carried out under some specific environment, and arm can't increase, and has only can solve this by tubing again and need, and therefore, construction cost is large, long in time limit.
Summary of the invention
The purpose of this utility model is to provide a kind of section pipe grafting formula branch pipe connection, solves in fixedly water supply, air feed and other low-pressure manifold, exists the problem that changes duct route or increase the arm difficulty.
To achieve these goals, the utility model Bian gets following technological scheme and implements: a kind of section pipe grafting formula branch pipe connection, formed by branch pipe connection body, check nut, wedge-type snap ring, seal ring, be provided with T shape three through holes in described branch pipe connection body, the orifice end that wherein connects outside arm is provided with the endosiphuncular tube screw thread, it is characterized in that described branch pipe connection body connects the two ends, straight-through aperture of cutting fixed tube and is provided with inner conical surface, two ends, the outside are provided with outside thread; One end of described check nut is provided with internal thread, the other end is provided with through hole, and check nut passes and cuts fixed tube internal thread rotation is combined on the outside thread that two ends, the branch pipe connection body outside are provided with; Described wedge-type snap ring is provided with an opening, external diameter is provided with male cone (strobilus masculinus), its tapering equates with the inner conical surface tapering that branch pipe connection body two ends are provided with, and the Outside diameter of male cone (strobilus masculinus) is greater than the end diameter of the Outside diameter of branch pipe connection body inner conical surface, the male cone (strobilus masculinus) end diameter greater than branch pipe connection body inner conical surface, the male cone (strobilus masculinus) coupling of wedge-type snap ring is in the inner conical surface of branch pipe connection body, be Spielpassung between endoporus and incision fixed tube external diameter, and on the large Transverse plane of tapering and check nut, the interior threaded hole bottom plane fit; Described seal ring is placed in the inner conical surface that branch pipe connection body two ends are provided with, is placed in the outside of cutting fixed tube, and is close to the little Transverse plane of wedge-type snap ring male cone (strobilus masculinus).
In the low-pressure manifolds such as water supply, air feed, when needs change or increase the arm circuit, cut main pipe and intercept a segment length less than the pipeline section of the branch pipe connection body length in the utility model, then the port of fixed tube is cut in an oblique insertion of end of branch pipe connection body and take advantage of a situation and insert, oppositely put, screw check nut, large Transverse plane on the wedge-type snap ring is under the pushing on plane, check nut internal thread bottom, inner conical surface on wedging branch pipe connection body, make the opening on the wedge-type snap ring and close, encircling the footpath and be subjected to contracting to clamp the incision fixed tube; Meanwhile, the little Transverse plane on the wedge-type snap ring squeezes and pushes away seal ring, and inner conical surface, internal diameter that the distortion of seal ring external diameter is close on the branch pipe connection body are close to the cylndrical surface of cutting fixed tube, thereby realizes the sealing between branch pipe connection body and two ends incision fixed tube.
The utlity model has reasonable in design, the advantages such as applicability good, mobility strong, grafting is convenient, construction cost is low, saving of work and time.
