Abstract
The utility model belongs to the technical field of fluid conveying and discloses a large-deflection pipeline stress eliminator which comprises an adapter ring-shaped protrusion arranged on an adapter, a shell body and a stopping block connected with the shell body. An O-shaped sealing ring is arranged between the shell body and the adapter ring-shaped protrusion. The adapter slides in the axial direction in the shell body, so that stress elimination due to thermal expansion in a pipeline system is achieved. Due to radial excursion of the adapter in the shell body, stress elimination caused by excursion angles and the like in the pipeline system is achieved. The O-shaped sealing ring cuts off and eliminates vibration generated at one end in the pipeline system. The problems such as axial displacement, angle direction displacement and vibration caused by temperature, pressure, self gravity and the like of pipeline systems such as a pneumatic transmission system, various water conveying systems, an oil product conveying system, a steam conveying system and a chemical engineering liquid material conveying system are solved. Equipment damage caused by stress concentration is completely eliminated, system service life is prolonged, and meanwhile project building cost is lowered.
Description
Technical field
The utility model relates to a kind of large deflection pipe stress canceller, belongs to fluid transfer technology practical field.
Background technique
At present, in fluid delivery process, for eliminating dilatation, the vibrating noise etc. of pipe-line system, be widely used pipeline compensator, slip joint, compensator etc.And these functions of the equipments are single, although solved the obvious deformation displacement that pipe-line system Yin Wendu, pressure variation produce, all do not have the stress of thoroughly eliminating pipeline to concentrate, use for a long time, easily produce the stress damage of pipeline and equipment, the working life of greatly reducing system.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of large deflection pipe stress canceller, integrate compensation of pipeline, flexible, incabloc function, to ensure that system pipeline and equipment are in natural extended configuration, with the concentrated problem of resolution system stress, concentrate to reduce pipeline and equipment stress the fatigue damage producing, extend system working life.
The technical solution of the utility model is: a kind of large deflection pipe stress canceller, it comprises adpting flange, it also comprises a housing and two ABAP Adapter, described adpting flange is arranged on one end of ABAP Adapter, the other end of ABAP Adapter is provided with ABAP Adapter ring-type projection, in ABAP Adapter, be set with a back-up ring, the internal diameter of back-up ring coordinates for movable with the external diameter of ABAP Adapter; Described housing is arranged on the outside of two relative ABAP Adapter ring-type projections, housing is connected with back-up ring by clamping bolt, between housing and ABAP Adapter ring-type projection, be provided with the O RunddichtringO being placed in sealed groove, described sealed groove is arranged in ABAP Adapter ring-type projection, between the end of two ABAP Adapter ring-type projections, leaves flexible gap L.
Described adpting flange and ABAP Adapter adopt fixed connection structure.
Flexible gap L between described two ABAP Adapter ring-type protruding end portions is 20-50mm.
The beneficial effects of the utility model are: this stress remover comprises the ABAP Adapter ring-type projection being arranged in ABAP Adapter, and the block being connected with housing, between housing and ABAP Adapter ring-type projection, are provided with O RunddichtringO.Sliding axially by ABAP Adapter in housing, has realized the stress elimination that pipe-line system produces because expanding with heat and contract with cold.Radial deflection by ABAP Adapter in housing, has realized the stress elimination that pipe-line system produces because of deviation angle etc.O RunddichtringO cuts off and has eliminated the vibrations that wherein one end produces.The problems such as axial displacement, angular displacement and vibrations that the reasons such as pipe-line system Yin Wendu, pressure, self gravitation such as air-transport system, various water conveying system, oil product transporting system, steam transmission system and chemical liquid material-transporting system cause are solved, thoroughly eliminate stress and concentrated the device damage producing, prolongation system working life, reduced engineering cost simultaneously.When the work of large deflection pipe stress canceller, the pipeline that its flange two ends connect, in the time expanding, drives two end adapters to slide to centre along housing, otherwise, to sliding in the other direction.Sealing is that two O RunddichtringOs by being pressed between housing and ABAP Adapter complete, and O RunddichtringO is to carry out material matching according to fed sheet of a media, temperature, pressure etc.When the pipeline connecting when flange two ends produces angular displacement, ABAP Adapter, along with the skew of pipeline, is utilized the gap of housing and ABAP Adapter, produces angle displacement.The position of ABAP Adapter limits, and is that the back-up ring by being fixed on clamping bolt on housing is realized.
Brief description of the drawings
Fig. 1 is a kind of structural drawing of large deflection pipe stress canceller.
Fig. 2 is the A enlarged view in Fig. 1.
In figure: 1, adpting flange, 2, clamping bolt, 3, housing, 4, O RunddichtringO, 4a, sealed groove, 5, back-up ring, 6 ABAP Adapter, 6a, ABAP Adapter ring-type projection.
Embodiment
Referring to accompanying drawing, structure of the present invention is described further.
Fig. 1,2 shows a kind of large deflection pipe stress canceller.In figure, this large deflection pipe stress canceller comprises adpting flange 1, housing 3 and two ABAP Adapter 6, adpting flange 1 is fixedly connected on one end of ABAP Adapter 6, the other end of ABAP Adapter 6 is provided with ABAP Adapter ring-type projection 6a, before ABAP Adapter 6 is fixedly connected with adpting flange 1, first in ABAP Adapter 6, be set with a back-up ring 5, the internal diameter of back-up ring 5 coordinates for movable with the external diameter of ABAP Adapter 6.Housing 3 is arranged on the outside of two relative ABAP Adapter ring-type projection 6a, housing 3 is connected with back-up ring 5 by clamping bolt 2, between housing 3 and ABAP Adapter ring-type projection 6a, be provided with the O RunddichtringO 4 being placed in sealed groove 4a, it is upper that described sealed groove 4a is arranged on ABAP Adapter ring-type projection 6a, between the end of two ABAP Adapter ring-type projection 6a, leaves flexible gap L=20-50mm.
While adopting technique scheme work, fluid feed line is easily produced on the adpting flange 1 that the concentrated part of stress is connected to these stress remover two ends, and install additional and connect pad and connecting bolt and fix, when adpting flange 1 two ends connect pipeline expand time, drive two end adapters 6 to slide to centre along housing 3, otherwise, to sliding in the other direction.Sealing is that two O RunddichtringOs 4 by being pressed between housing 3 and ABAP Adapter 6 complete, and O RunddichtringO 4 is to carry out material matching according to fed sheet of a media, temperature, pressure etc.When the pipeline connecting when adpting flange 1 two ends produces angular displacement, ABAP Adapter 6, along with the skew of pipeline, is utilized the gap of housing 3 and ABAP Adapter 6, produces angle displacement.The position restriction of ABAP Adapter 6 is that the back-up ring 5 by being fixed on housing 3 with clamping bolt 2 is realized.ABAP Adapter 6 connects by flange or is welded direct on the pipeline of pipe-line system, is out of shape, to reach the object of eliminating pipeline stress with the distortion of pipeline.
