Abstract
The invention discloses an extruding pipeline connection seal mechanism for a cement septic tank, which comprises a variable-diameter pipeline joint and an eccentric circle seal ring, wherein the variable-diameter pipeline joint is hollowly cylindrical; an end face, located in the cement septic tank, of the variable-diameter pipeline joint is an internal end face; an end face which is located outside the cement septic tank and connected with an external pipeline is an external end face; the diameter of the internal end face is greater than that of the external end face; a check ring is arranged on an external wall of the variable-diameter pipeline joint, and used for fixing an axial position of the variable-diameter pipeline joint in a mounting process; the eccentric circle seal ring is a hollow circular table rubber ring with certain thickness; the diameter of the eccentric circle seal ring is between those of the internal end face and the external end face of the variable-diameter pipeline joint; and an internal hole of the eccentric circle seal ring is in an eccentric design. The pipeline connection seal mechanism is simple in structure; the variable-diameter pipeline joint is designed to be circular-table-shaped, is sealed by extruding the eccentric circle seal ring from inside to outside, and does not require flange or threaded connection; and the eccentric circle seal ring can adjust a circle center, so that internal stress between the external pipeline and the variable-diameter pipeline joint can be eliminated conveniently.
Description
Technical field:
The present invention relates to the sealing for tubing joints technical field, particularly a kind of cement septic tank connects sealing mechanism with extrusion type pipeline.
Background technique:
Laying or pipe laying have dual mode at present, and a kind of is to utilize pipeline flanges, adopts traditional flange connection, by a plurality of set screws are installed at the interface circumference mouth of pipe compression of docking is linked together, this installation method is loaded down with trivial details, time-consuming taking a lot of work, and also cost is higher; Another kind is to adopt the street corner of living to install to connect, and arranges with the footpath outside thread at two mouths of pipe that dock, and the internal thread attaching nut of coupling is installed at this outside thread.But above dual mode all is not suitable for the pipeline of cement septic tank or wet pit to be connected, especially inside and outside wall be arc surface or inclined-plane cement septic tank or wet pit, during in addition owing to installation, the mounting interface of cement septic tank or wet pit and the axis of pipeline are often from handing over large error, the pipeline bindiny mechanism that has first is difficult to eliminate the internal stress of the jointing that this error brings, and has hidden danger of quality.
Summary of the invention:
Given this, be necessary to design a kind of cement septic tank and connect sealing mechanism with extrusion type pipeline.
A kind of cement septic tank connects sealing mechanism with extrusion type pipeline, comprises tapered pipeline joint and eccentric circle seal ring.
Wherein, the tapered pipeline joint is the cylindric of hollow, and its end face that is positioned at the cement septic tank is interior edge face, and being positioned at cement septic tank end face outer and that external pipe joins is the exterior edge face, the interior edge face diameter is greater than the exterior edge face, and the caliber of tapered pipeline joint is transitioned into the exterior edge face gently by interior edge face; The outer wall of tapered pipeline joint is provided with all back-up rings when be used for installing fixedly the tapered pipeline joint shaft to the position, the face of back-up ring subtend exterior edge face is the surface of contact of itself and cement septic tank, and the cement septic tank inner wall surface of the shape of surface of contact and its installation place is complementary.
The eccentric circle seal ring is for there being certain thickness hollow round table body rubber circle, and its diameter is between tapered pipeline joint interior edge face and exterior edge face, and the eccentric circle ring inner hole adopts eccentric design, is provided with the projection of a few axially-aligned at eccentric circle seal ring circumference.
During assembling, the tapered pipeline joint is embedded on the cement septic tank wall, the exterior edge face is outside, and surface of contact and cement septic tank inwall offset, and build moulding.When being connected with external pipe, the external pipe interface is deep in the septic tank by the exterior edge face, the eccentric circle seal ring is enclosed within the less end of external pipe interface outer wall and eccentric circle seal diameter towards tapered pipeline joint exterior edge face, afterwards the eccentric circle seal ring is pushed by the outside end face of interior edge face together with external pipe, eccentric circle seal ring and tapered pipeline joint are closely cooperated, in this process, can adjust the external pipe shaft core position to eliminate internal stress by rotating the eccentric circle seal ring.
Preferably, interior edge face is the shape of cutting sth. askew, and its kerf is consistent with the surface of contact shape.
Preferably, when the cement septic tank of tapered pipeline joint resettlement place was cambered surface, surface of contact was the cambered surface of outside head face hump.
Preferably, when the cement septic tank inclined-plane of tapered pipeline joint resettlement place, surface of contact is the inclined-plane.
Preferably, the projection on the eccentric circle seal ring circumference is pointed dentation.
The present invention is simple in structure, and the tapered pipeline joint design is become truncated cone shape, pushes from inside to outside to seal by the eccentric circle seal ring, need not flange or is threaded; The adjustable pitch circle heart of eccentric circle seal ring can be eliminated the internal stress between external pipe and the tapered pipeline joint easily simultaneously.
