Summary of the invention
For above-mentioned prior art Problems existing with not enough, the utility model adopts the jointing at pipe fitting, from outside to inside, arranges O shape circle and circle gear respectively, during application, pipe termination being provided with outer ramp down angle along interface direct patch into, wherein, the O shape circle of silicone rubber matter is used for the sealing between pipe fitting and pipe, the degree of depth of circle gear for limiting pipe inserting pipe elements body, the anti-aging property utilizing the O shape of silicone rubber matter to enclose and the annexation of retractable between pipe fitting and pipe, eliminate the technological scheme because of weathering or body of wall sedimentation generation pipeline fracture leakage, a kind of straight cutting self sealing Plastic down pipe part is provided, be intended to make Plastic down pipe road, reach easy to connect, efficiency is high, environmental protection, cost is low, the object of hidden danger of stopping a leak.
The purpose of this utility model is achieved in that a kind of straight cutting self sealing Plastic down pipe part, comprises pipe fitting, interface, O shape circle, circle gear, wherein: described pipe fitting is that hollow and thin-walled pipeline moulds material matter component; The passage that the inner chamber of pipe fitting is connected with the external world is called interface; Described interface is cylinder tube shape, and interface is respectively equipped with O shape circle and circle gear from outside to inside; Wherein, described O shape encloses the component of the silicone rubber matter for ring, circular in cross-section, and O shape circle is as inserts, when molding and forming pipe fitting, along the inwall circumference of described interface, compound is fixedly embedded in the inwall place of interface, and the inner ring diameter of O shape circle is less than the inner diameter of described interface; Described circle keeps off the flange for the ring arranged along the inwall circumference of interface; A certain distance is provided with between O shape circle and circle keep off.
Working principle and beneficial effect
During application, pipe termination being provided with outer ramp down angle along interface direct patch into, wherein, the O shape circle of silicone rubber matter is used for the sealing between the inwall of the described interface of pipe fitting and the outer wall of pipe, the degree of depth of circle gear for limiting pipe inserting pipe elements body.
This apparatus structure is simple, connects reliable, the anti-aging property utilizing the O shape of silicone rubber matter to enclose, the hidden danger that the Plastic down pipe road eliminating external mounted is leaked because of weathering generation; Utilize the annexation of retractable between pipe fitting and pipe, the hidden danger that the Plastic down pipe road eliminating built-in type is leaked because of body of wall sedimentation generation fracture.
Above-mentioned, the utility model adopts the jointing at pipe fitting, arranges O shape circle and circle gear from outside to inside respectively, during application, pipe termination being provided with outer ramp down angle along interface direct patch into, wherein, the O shape circle of silicone rubber matter is used for the sealing between pipe fitting and pipe, the degree of depth of circle gear for limiting pipe inserting pipe elements body, the anti-aging property utilizing the O shape of silicone rubber matter to enclose and the annexation of retractable between pipe fitting and pipe, eliminate the technological scheme because of weathering or body of wall sedimentation generation pipeline fracture leakage, overcome prior art and there is connection trouble, efficiency is low, not environmentally, cost is high, the problems and shortcomings of easy leakage, a kind of straight cutting self sealing Plastic down pipe part provided, Plastic down pipe road is reached easy to connect, efficiency is high, environmental protection, cost is low, the object of hidden danger of stopping a leak.
