Description
Technical field
The utility model relates to machine-building measurement technique field, specifically relates to a kind of bellows expansion joint assembly parts that can simultaneously test.
Background technique
Now, the industries such as large-scale thermoelectricity plant, cement and smelting iron and steel generally adopt pipe method conveying solid substance granule, and most operating mode is interrupted conveying.The solid particle temperatures as high 300 DEG C ~ 500 DEG C carried under conventional operating mode, the pipeline that is heated certainly leads to corresponding internal stress.Internal stress has very strong destructiveness, brings potential safety hazard to conduit running, must take corresponding control measures in pipework, just can accomplish safe operation, and under prior art condition, configuring pipes compensation device is one of the most effective technical measures in the duct.Expansion joint is the additional stress for compensating because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Due to it as a kind of can the elastic compensation element of free-extension, the advantages such as reliable operation, functional, compact structure, have been widely used in the departments such as chemical industry, metallurgy, nuclear energy.Expansion joint is also slip joint traditionally, or corrugated expansion joint, being utilize effective dilatation of the elastic element of corrugated expansion joint expansion joint to absorb pipeline, conduit or container by reason and a kind of compensation device of the dimensional changes produced such as expanding with heat and contract with cold, belonging to a kind of compensating element.Bellows expansion joint is a kind of expansion joint made with metal bellows, and it can stretch in the axial direction, also allows a small amount of bending.Bellows expansion joint in use can be regular experience process of expansion and contraction, stressed complexity is easily damaged, and needs reliability trial to verify and qualifiedly could to use.
Before 20 century 70s, mainly analytic method is adopted to the analysis of bellows expansion joint, according to the ess-strain value of the what-if housing of approximate simple beam, approximate cylinder housing; Adopt non linear finite element analysis stress after 20 century 70s, the problems such as intensity, vibration, stability can be solved preferably; Modern age artificial-intelligent be also used to the research of bellows.While carrying out theoretical research, laboratory test is used to the Performance And Reliability studying bellows.
At present, be all test for single expansion joint to the routine test of bellows expansion joint, there is test number (TN) more, test efficiency is lower, the defect that proof strength is larger.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of bellows expansion joint assembly parts that can simultaneously test, can test two bellows expansion joints simultaneously, anatomical connectivity is simple, convenient during use, test efficiency is high, solves the defect that existing equipment single test intensity is large.
The technical solution of the utility model is achieved in that
A kind of bellows expansion joint assembly parts that can simultaneously test, comprise two bellows expansion joints, the first flange, two the second flanges and two sealing plates, between the end face of two described bellows expansion joint one end by described first flange seal welding together, the end face of two described bellows expansion joint the other ends respectively second flange seal described with welds, second flange of this end is detachably fixedly connected with a described sealing plate respectively, and the second flange of this end is provided with seal ring with between corresponding sealing plate; Be communicated with in the middle part of two described bellows expansion joints, the downside of each described bellows expansion joint is provided with intake-outlet, and the upside of each described bellows expansion joint is provided with relief opening.
As further improvement of the utility model, described sealing plate is steel plate.
As further improvement of the utility model, described seal ring is O RunddichtringO.
As further improvement of the utility model, described second flange is bolted to connection with between corresponding sealing plate.
The beneficial effects of the utility model are: the utility model provides a kind of bellows expansion joint assembly parts that can simultaneously test, be specially and can test two bellows expansion joints simultaneously, anatomical connectivity is simple, convenient during use, compared with prior art, reduce test number (TN), substantially increase test efficiency, solve the defect that existing equipment single test intensity is large.
