Abstract
The utility model is a pipe joint without radial O-shaped sealing ring. The joint comprises an inner core tube, a joint body, a sealing part and a fixing device. The differences are that the outer wall of the joint body is opened with thread near the ends, but the interior appears circular cone inclined plane; the sealing part is a circular cone flowering set, the taper of lateral surface is corresponding to the circular cone in the pipe body, a gap is left to accommodate camp-on body between the inner wall of hole and the core tube; the fixing device is a threaded sleeve, a thread which is opposite to the thread on the ektexine of body is opened on the inside wall of the threaded sleeve to support the camp-on body and the inner core tube which is installed independent.
Description
The utility model relates to pipe connection, particularly a kind of pipe joint.
Existing pipe joint utilizes the rib-loop connection to be connected two kinds with non-rib-loop, for pipe that can not the Cairo line as aluminium-plastic composite pipe etc., adopt has the radially pipe joint of O RunddichtringO more, this kind pipe joint must apply external force the O RunddichtringO is pressed on realization sealing on the body when connecting, but in order to compress the O RunddichtringO, body is deformed, the plastics of extrusion are aging easily, and aging stratification will take place the aluminium-plastic composite pipe of heat processing and forming, cause the body seepage.
The purpose of this utility model provides a kind of radially pipe joint of O RunddichtringO that need not.
The purpose of this utility model is achieved in that this new tube joint comprises inner core tube, adapter body, Sealing and fixing device, and different is: near the end, have screw thread, and the inside end is the truncated cone inclined-plane on the outer wall of described adapter body; Described Sealing is the truncated cone cover of blooming, and the tapering of its outer side surface and body truncated cone inside is corresponding, stays between its inner hole wall and the core pipe and can hold the slit of waiting to take over body; Described fixing device is a threaded sleeve, offer on the madial wall of this threaded sleeve with tube wall on offer the corresponding screw thread of screw thread, to wait to take over body and also have independent inner core tube of installing in order to support.
Because this new tube joint is when connecting body, body to be taken over is in the core pipe and blooms between the cover, when threaded sleeve and body screw, threaded sleeve pushes the cover of blooming, make it will to wait to take over press to the core pipe and fixing and compression axis to the seal ring sealing, need not bear external force owing to wait to take over, more need not distortion, then can not make and wait to take over aging seepage.And the cover bottom is provided with the effect that O-ring seal can be played in the leakproof foundation ring because bloom, and again because outside the interior ring of leakproof foundation ring, the mouth of hook 8 that has a circle to protrude inwards can hook and treat the junctor inwall, has more strengthened treating the leakproof of taking over body.Fig. 1, Fig. 2 are two kinds of prevailing mode of executions of the present utility model, and concrete when implementing the utility model, the material of adapter body, threaded sleeve can be with plastics or metal, and inner core tube is a metal, and the cover of blooming is plastics.
Below in conjunction with accompanying drawing technical elements of the present utility model is further described.
Fig. 1 is the utility model straight coupling structural representation;
Fig. 2 is the structural representation of the utility model tee union;
Fig. 3 is the structural representation of blooming and overlapping.
Claims (1)
1, a kind of pipe joint comprises inner core tube, adapter body, Sealing and fixing device, it is characterized in that: described inner core tube (1) is what separate with adapter body (2); Near the end, have screw thread, and the inside end is the truncated cone inclined-plane on the outer wall of described adapter body (2); Described Sealing (4) is the truncated cone cover of blooming, and the tapering of its outer side surface and body truncated cone inside is corresponding, stays between its inner hole wall and the core pipe and can hold the slit of waiting to take over body; Described fixing device is threaded sleeve (3), offer on the madial wall of this threaded sleeve (3) with tube wall on offer the corresponding screw thread of screw thread.
