Description

A kind of crossover sub device for detecting sealability
Technical field
The utility model is related to the air tightness test technical field of pipe fitting, more particularly, to a kind of inspection of crossover sub sealing Survey device.
Background technology
Crossover sub includes steel modeling, porcelain carving, copper modeling etc., and by taking steel-plastic joint as an example, steel plastic pipe is moulded also known as PE steel and changed Joint, is widely used among current production, life, for example, will largely be used in combustion gas, natural gas transportation pipeline (outer combustion gas pipeline is generally PE pipelines to steel modeling crossover sub, and it is generally steel pipe to get in, and needs to be moulded using steel in switching process Crossover sub).
Traditional steel modeling crossover sub, itself includes lengths of steel pipes (one section of steel pipe) and modeling pipeline section (usually one section of PE pipe), One end of lengths of steel pipes docks to form linkage section with one end of modeling pipeline section, and linkage section is more by lengths of steel pipes one end and modeling pipeline section one end clamping Formed, and sealed using sealing ring (linkage section would generally set some concaveconvex structures coordinate clamping, in lengths of steel pipes Flange with modeling pipeline section on draw-in groove mutually fasten, anchor ear can also be set outside linkage section and further held tightly), lengths of steel pipes it is non- Connection end is referred to as steel pipe end, and the front of motor for moulding pipeline section is referred to as moulding pipe end, and modeling pipe end can mould pipe (PE pipes) welding with waiting to dock, Steel pipe end can be connected with steel tube screw thread to be docked, welds or be docked by other structures.Because steel modeling crossover sub is Gas, liquid transportation art are applied to, so its sealing needs to be guaranteed, before dispatching from the factory, sealing inspection are carried out to it Survey.
When prior art carries out sealing-in to steel modeling crossover sub, steel modeling conversion is generally placed on using sealing gasket or sealing ring and is connect The outside at head two ends (steel pipe end and modeling pipe end), while being clamped in steel with force application apparatus such as jack or hydraulic cylinders moulds crossover sub Two ends, so that two ends of sealing gasket or sealing ring and steel modeling crossover sub form sealing.
At least there is following defect in above structure:1) sealing survey is carried out by the way of crossover sub or pipeline is placed on Examination, sealing ring needs to be dismantled after test, on the one hand extends test man-hour, on the other hand, there is sealing ring and does not dismantle It is mixed into the risk of later process;2) crossover sub is sealed using jacking platen and sealing ring is placed on steel modeling conversion Joint two ends periphery, and when being sealed with hydraulic cylinder (or cylinder) clamping crossover sub two ends, the more difficult control of dynamics, clamping The too small sealing that may make crossover sub end of active force is not firm, so as to influence the accuracy of experiment, brings in quality Erroneous judgement, the active force of clamping can make greatly very much crossover sub deform, cause crossover sub end face (pipe end) out-of-flatness, so that Obtaining crossover sub cannot form sealing, bring the erroneous judgement in quality;3) cannot be adjusted flexibly according to the requirement of the material of part to be detected (such as porcelain carving crossover sub cannot bear larger axial stress, should now take side close for sealing means and sealing position Envelope mode is effectively sealed, and steel modeling crossover sub can bear appropriate axial stress, can now take end face seal mode Effectively sealed.);4) detection machine is only capable of detecting the crossover sub of same specification, it is impossible to be adjusted flexibly, the scope of application is narrow It is narrow.
Utility model content
A kind of crossover sub device for detecting sealability that the utility model is provided, it is high that it possesses simple structure, detection efficiency Advantage, using the utility model detection means can only with one detection machine testing different size crossover sub, use When only need adapt to change connector and limit base, in addition, can also flexibly be turned according to the stress characteristics of crossover sub to be detected Become sealing means, it is applied widely.
For the detection efficiency for solving crossover sub device for detecting sealability in the prior art is low, complex structure, to forget dismounting close Seal causes to be mixed into the risk of later process and the narrow technical problem of the scope of application, a kind of conversion that the utility model is provided Joint tighness detection means, including installation pedestal, crossover sub and be oppositely disposed in the compression in the installation pedestal Frock and limit base;Wherein, compression tooling includes compression cylinder and the connector for being connected to compression cylinder output end, in connector Front end open up draw-in groove, draw-in groove bottom opens up the passage of connection connection rostral wall, for transmission medium detecting sealing property;This Outward, the also sealing ring including being embedded in draw-in groove;Wherein limit base is arranged in installation pedestal using removably, and spacing Seat is provided with the stopper slot of crossover sub and limitation crossover sub axial float.
Further, a kind of crossover sub device for detecting sealability that the utility model is provided, wherein, draw-in groove inner side opens up Embeded slot, the function for realizing installation and fixed seal ring.
Further, a kind of crossover sub device for detecting sealability that the utility model is provided, wherein, draw-in groove bottom opens up Embeded slot, the function for realizing installation and fixed seal ring.
Further, a kind of crossover sub device for detecting sealability that the utility model is provided, wherein, connector is using just In the output end connection of the movable connection method and compression cylinder of dismounting.
Compared to the prior art a kind of crossover sub device for detecting sealability of the utility model has advantages below:1) seal Circle is embedded in the draw-in groove of connector, is different from traditional mode being placed on sealing ring on crossover sub or on pipe fitting, a side Face, it is to avoid cumbersome sealing ring dismounting operation, improve detection efficiency, on the other hand, it is to avoid forget to tear open sealing ring cause it is close The occurrence of seal follows crossover sub to enter later process;2) limit base is connected to installation base using dismountable mode Seat, and connector, equally using the output end for being detachably coupled to compression cylinder, this allows for the application can basis Actual crossover sub specification to be detected flexibly changes corresponding connector and limit base, expands the scope of application;3) sealing ring can Characteristic according to actual crossover sub to be detected is adjusted flexibly installation site, such as porcelain carving crossover sub cannot bear larger axle To stress, side sealing means should be now taken effectively to be sealed, steel modeling crossover sub can bear appropriate axial stress, Can now take end face seal mode effectively to be sealed, equally further expand the scope of application of the application.
