Abstract
The utility model provides an easy dismounting device of pipeline instrument, which belongs to a device for oil field production. The easy dismounting device of pipeline instrument is provided with a connecting pipe. One end of the connecting pipe is connected with a pipeline connector, and the other end is provided with a screw cap through screw. A hollow groove is provided outside the screw cap and an annular projection is provided at the inside of the screw cap. One end of a housing which is equipped outside the connecting pipe through screw thread is equipped together with the screw cap, and the other end is fixed with the pipe body. A sealing gasket is provided between the housing and the annular projection on the screw cap. The easy dismounting device can conveniently realize dismounting of instrument or valve through rotating the connecting pipe for causing the connecting pipe to retreat into the housing or extend out from the housing. The easy dismounting device furthermore has the following advantages: short operation time, low cost and ensured normal production.
Description
Technical field
The utility model provides a kind of field produces device, the device on especially a kind of pipeline.
Background technology
In oilfield process, can be connected with some measuring instruments or by-pass valve control usually on the pipeline.Generally require these instrument or the valve can dismounting, so that maintenance, change.But because the rigidity of pipeline is big, poor flexibility, dismounting is difficulty very.As the water meter in the distributing room for water injection, must be welded on again during installation on the pipeline with the gas welding table pipelines on two sides of cutting off the water supply during dismounting, very inconvenience, the operating time is long, and the cost height influences ordinary production.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device easy to assemble of pipeline instrument, the convenience of raising dismounting.
The utility model is to realize like this, the device easy to assemble of pipeline instrument, it has tube connector, one end and the conduit coupling of tube connector links together, the other end is equipped with nut by screw thread, the outside of nut has dead slot, inboard that annular protrusion is arranged, be installed in housing one end of tube connector outside and nut is installed together, the other end is fixed with body by screw thread, between the annular protrusion on housing and the nut sealing gasket arranged.
Adopt the device easy to assemble of the pipeline instrument of said structure, by the pipe that is rotationally connected, make in its indentation housing or stretch out outside the housing, can realize the dismounting of instrument or valve easily, the operating time lacks, and cost is low, has guaranteed ordinary production.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.
As shown in drawings, the device easy to assemble of the pipeline instrument of the utility model, it has tube connector 4, one end and the conduit coupling 3 of tube connector links together, the other end is equipped with nut 5 by screw thread, the outside of nut has dead slot 10, inboard that annular protrusion 6 is arranged, be installed in housing 8 one ends of tube connector outside and nut is installed together, the other end is fixed with body 9 by screw thread, sealing gasket 7 is arranged between the annular protrusion on housing and the nut.
During use, the mounting means of instrument 1 on pipeline 2 promptly connects by conduit coupling 3 with existing identical.When needing the dismounting instrument, unload loose conduit coupling earlier, rotating screw cap 5 then, make itself and housing leave certain distance, by instruments such as the pipe wrench pipe that is rotationally connected, make in the one section indentation housing again, conduit coupling just can separate fully, and instrument will be taken off easily.When instrument was installed, reverse operating got final product.
Described conduit coupling can be snap joint.
