Abstract
The utility model relates to a squeezing type pipeline connecting sealing mechanism for a cement septic tank. The mechanism comprises a tapered pipeline joint and an eccentric circle sealing ring. The tapered pipeline joint is in a hollow cylindrical shape; the end surface arranged in the cement septic tank is an inner end surface; and the end surface that is arranged outside the cement septic tank and is connected with an external pipeline serves as an outer end surface, wherein the inner end surface is larger than the outer end surface. The outer wall of the tapered pipeline joint is provided with a loop of retainer ring that is used for fixing the axial direction of the tapered pipeline joint during installing. In addition, the eccentric circle sealing ring is a hollow cone rubber ring with a certain thickness, wherein the diameter of the eccentric circle sealing ring is between the dimension of the inner end surface and the dimension of the outer end surface of the tapered pipeline joint; and an inner hole of the eccentric circle sealing ring employs an eccentric design. The provided mechanism has the simple structure. The tapered pipeline joint is designed into the circular truncated cone type; and sealing is realized by squeezing of the eccentric circle sealing ring from inside to outside without the need of flange connection or threaded connection. Meanwhile, the circle center of the eccentric circle sealing ring can be adjusted, so that the internal stress between the external pipeline and the tapered pipeline joint can be eliminated conveniently.
Description
technical field:

background technique:
Laying or pipe laying have two kinds of modes at present, and a kind of is to utilize pipeline flanges, adopts traditional flange connection, by a plurality of set screws are installed at interface circumference, the mouth of pipe of docking is compressed and 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 at two mouths of pipe that dock, same footpath outside thread is set, and the internal thread attaching nut of coupling is installed on this outside thread.But above two kinds of modes are all 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 due 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 first having 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.
Septic tank connects a sealing mechanism with extrusion type pipeline, comprises tapered pipeline joint and eccentric circle seal ring.
Wherein, tapered pipeline joint is the cylindric of hollow, and its end face that is positioned at cement septic tank is interior edge face, and being positioned at cement septic tank end face outer and that external pipe joins is exterior edge face, interior edge face diameter is greater than exterior edge face, and the caliber of tapered pipeline joint is transitioned into exterior edge face gently by interior edge face; The outer wall of tapered pipeline joint be provided with one week back-up ring when installing fixedly tapered pipeline joint shaft to 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 matches.
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 eccentric circle ring inner hole adopts eccentric design, is provided with the projection of a few axially-aligned on eccentric circle seal ring circumference.
During assembling, tapered pipeline joint is embedded on cement septic tank wall, exterior edge face is outside, and surface of contact and cement septic tank inwall offset, and build moulding.While being connected with external pipe, external pipe interface is deep in septic tank by exterior edge face, eccentric circle seal ring is enclosed within to external pipe interface outer wall and the less one end of eccentric circle seal diameter towards tapered pipeline joint exterior edge face, afterwards 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 external pipe shaft core position to eliminate internal stress by rotating eccentric circle seal ring.
Preferably, interior edge face is the shape of cutting sth. askew, and its kerf is consistent with surface of contact shape.
Preferably, when the cement septic tank of tapered pipeline joint resettlement place is cambered surface, the cambered surface that surface of contact is outside head face hump.
Preferably, when the cement septic tank inclined-plane of tapered pipeline joint resettlement place, surface of contact is inclined-plane.
Preferably, the projection on eccentric circle seal ring circumference is pointed dentation.
The utility model is simple in structure, and tapered pipeline joint design is become to truncated cone shape, pushes from inside to outside to seal, without flange or be threaded by eccentric circle seal ring; The adjustable center of circle of eccentric circle seal ring, can eliminate the internal stress between external pipe and tapered pipeline joint easily simultaneously.
