Abstract
The utility model relates to a telescopic and corrugated composite pipeline compensator, for using the technical field of that the thermal state operation pipe network thermal expansion. The telescopic compensator is provided with a corrugated compensator, one end at the takeover (5) of the corrugated compensator is conneceted with a core pipe (1) of the telescopic compensator sleeve, and the other end of the corrugated compensator is connected with an outer sleeve (4) of the telescopic compensator. When the heating medium passes through the pipeline, the pipeline is elongated by the heating medium. The corrosion condition of the environment is interrupted to the corrugated pipe by the telescopic compensator; the break of the corrugated pipe is prevented. The telescopic and corrugated composite pipeline compensator can elongate and compress during the working time, and does not leak and break, which is a safety and reliability compensator.
Description
Technical field
The utility model relates to a kind of sleeve ripple combined type pipeline compensator, is used for the thermal expansion technical field when hot operation pipe network is cold and hot to be changed.
Background technique
Pipeline compensator commonly used both at home and abroad at present has two kinds, sleeve expansion joint and FlexbleJoint.These two kinds of products respectively have pluses and minuses and its developing history, and sleeve expansion joint history is more of a specified duration, and its main damage mode is a corrosion leakage, does not break but can not cause, and maintenance workload is big in the using process.(application number: 99207040.6) " the compound core tube type pipeline compensator of high finishingness stainless steel " patent, it is to be provided with the compound layer of stainless steel on the outer surface of former sleeve compensator core pipe though the applicant successfully invented in 99 years.Prolong greatly working life like this, the leakage example is not arranged so far as yet, but because early stage sleeve expansion joint influences in the user deeply, a lot of users still do not accept sleeve expansion joint.FlexbleJoint uses in short-term and can not leak, thereby the user is popular, yet after long the use, corrugated conduit compensator break accident all takes place in a lot of areas, in case accident takes place, can't maintenance and repair, blowing out can only discharge water, the compensator that more renews, in recent years, in Taiyuan, ground such as Beijing, Shenyang, grand celebration, Mudanjiang causes major diameter FlexbleJoint break accident, causes city heat supply to be in halted state, cause inconvenience in life to heat supply user, heating enterprise causes serious economy loss.Thereby the area that has dare not be used FlexbleJoint and be changed sleeve expansion joint in a large number.For example: 9 years Taiyuan City, 2001 the Daqing, the FlexbleJoint that all underground pipe network has been installed in usefulness changes sleeve expansion joint into, has caused very big economic loss.
Technology contents
A kind of both wear-resistant, difficult leakage that the purpose of this utility model is to provide is difficult for a kind of sleeve ripple combined type pipeline compensator that bellows bursts is caused a serious accident again.
The purpose of this utility model is achieved in that
The utility model is made up of sleeve expansion joint and FlexbleJoint, and FlexbleJoint is housed in the sleeve expansion joint, and FlexbleJoint one end is connected with the core pipe of sleeve expansion joint, and the other end of FlexbleJoint is connected with the outer sleeve of sleeve expansion joint.
The utility model is owing to combine sleeve expansion joint and FlexbleJoint; two kinds of compensators are had complementary advantages; by the etching condition of sleeve expansion joint blocking-up environment to bellows; prevent bellows bursts; therefore this sleeve ripple combined compensator plays the effect of double shielding, extends simultaneously during work or compresses, and neither can leak; more can not break, be a kind of safe and reliable compensator.
Description of drawings
Accompanying drawing 1 is a main sectional view of the present utility model:
Embodiment
The utility model is that FlexbleJoint is housed in the sleeve expansion joint, and FlexbleJoint is taken over 5 one ends and is connected with the core pipe 1 of sleeve expansion joint, and the other end is connected with the outer sleeve 4 of sleeve expansion joint.Sleeve expansion joint adopts the compound compensator of high finishingness stainless steel; it includes core pipe 1, packing retaining ring 2, stuffing box packing 3, outer sleeve 4; compensator direct-burried safety cover; FlexbleJoint is made up of adapter 5, bellows 6, honeycomb duct 7,8; the FlexbleJoint two ends are for taking over 5; by bellows 6 two pipe nipples are welded as a whole in the middle of taking over 5, an end of honeycomb duct 7,8 welds with taking over 5 internal surfaces respectively, and the other end of honeycomb duct 7,8 is a pivot bush unit.Compensator direct-burried safety cover one end links to each other with the overcoat 4 of pipeline compensator; the other end links to each other with pipeline compensator core pipe 1; when pipeline has thermal medium to pass through; pipeline is subjected to thermal stretching; be installed on the pipeline compensator by compression; compensator core pipe 1 and bellows 6 plays the effect that temperature variation causes the thermal expansion of pipeline compensation by compression and length shortens simultaneously.
Claims (1)
1, a kind of sleeve ripple combined type pipeline compensator, form by sleeve expansion joint and FlexbleJoint, it is characterized in that: FlexbleJoint is housed in the sleeve expansion joint, FlexbleJoint is taken over (5) one ends and is connected with the core pipe (1) of sleeve expansion joint, and the other end that FlexbleJoint is taken over (5) is connected with the outer sleeve (4) of sleeve expansion joint.
