Abstract
An instrument connecting device is mainly used for connecting an instrument and a pipeline system, and comprises a straight pipe (1), a measuring pipe (2), a valve I (3) and a valve II (4). The instrument connecting device is characterized in that an instrument interface (5) is arranged at the upper end of the straight pipe (1), a pipeline interface (6) is arranged at the lower end, a valve I (3) is arranged on the pipe wall above the pipeline interface (6), a measuring pipe (2) with a valve II (4) at the top thereof is connected to the straight pipe (1) above the valve I (3), and a blow-off pipe interface (7) is arranged at the other end of the measuring pipe (2). The utility model has the advantages of simple structure and convenient use, and neither gas nor liquid is discharged from the pipeline while the instrument is replaced, so that no harm is caused to the human body, and the instrument can be checked without being dismounted.
Description
Technical field
The utility model relates to the instrument connection transition apparatus that a kind of instrument is connected with pipe-line system.
Background technique
Current, when people install instrument on various pipelines, be as transition piece instrument to be installed on the pipeline with throughway valve, owing to there is not pressure release passage above the throughway valve, gas when changing instrument in the passage or liquid are discharged the back commute human body are worked the mischief; Must unload from pipeline when checking the accuracy of instrument, influence is produced and is normally carried out.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and providing a kind of does not have gas or liquid to discharge when changing instrument in the pipeline, and need not dismantle the instrument connection transition apparatus that instrument can be carried out verification to it.
The purpose of this utility model is achieved in that this instrument connects transition apparatus and is made up of straight tube, survey pipe, valve I, valve II, the straight tube upper end is provided with instrumentation tap, the lower end is provided with pipe joint, the tube wall of pipe joint top is provided with valve I, be provided with the survey pipe of valve II above being connected with on the straight tube above valve I, survey the pipe the other end and be provided with the drain pipe interface.
During use, this device is connected on the pipe-line system by the pipe joint above the straight tube, throttle down II opens valve I and can detect gas in the pipeline or liquid; Throttle down I opens valve II after connecting drain pipe on the drain pipe interface, gas or liquid in the straight pipeline can be discharged from drain pipe, and then changes instrument; On the drain pipe interface, connect and open valve I after the corresponding standard instrument and valve II can proofread and correct the instrument above the instrumentation tap.
Advantage of the present utility model: simple in structure, easy to use, when changing instrument, there are not gas or liquid to discharge in the pipeline, can not work the mischief by human body, and need not dismantle instrument and can carry out verification it.
Description of drawings
Accompanying drawing is a structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: this instrument connects transition apparatus and is made up of straight tube 1, survey pipe 2, valve I 3, valve II 4, straight tube 1 upper end is provided with instrumentation tap 5, the lower end is provided with pipe joint 6, the tube wall of pipe joint 6 tops is provided with valve I 3, be provided with the survey pipe 2 of valve II 4 above being connected with on the straight tube 1 above valve I 3, survey pipe 2 the other ends and be provided with drain pipe interface 7.
Claims (1)
