Carbonoxide and micro rare gas, such as helium and argon.Natural gas is before being sent to end user, to help leak detection, also
With mercaptan, thiophane etc. smell is added to natural gas.
With the continuous development of energy technology, many cells all use natural gas as fuel, this is just needed in the cell
The steam line for setting up natural gas avoids the presence of leakage in order to which safety often will repair monitoring to the steam line in cell
Gas phenomenon, causes security risk.
Current detection instrument can only be detected gas leak phenomenon, cannot leak electricity to pipeline and carry out temporary cover.
Utility model content
The utility model aim be intended to provide it is a kind of it is simple and reasonable, can leak electricity and face to natural gas line
When cover and to the detection of natural gas device that is detected of leakage air pressure.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of detection of natural gas device, including two symmetrically arranged semicircle anchor ears, described two anchor ears insides are along axis
To groove is provided with, the groove opened up on described two anchor ears is closed composition annular；
Difference has instruction to manage on the outside of the anchor ear, and the instruction pipe is inserted into anchor ear end and is connected to groove；
The instruction pipe includes the upper tube body of lower tube body, transparent material, and the lower tube body both ends are run through, on the upper tube body
End seal is closed, and the upper tube body lower end is placed on lower tube body upper end and is connected by screw-thread fit, and floating diaphragm plate is equipped in the upper tube body,
The floating diaphragm plate outer rim and upper tube body inner wall airtight connection.
It further limits, described two anchor ear both ends are both provided with connecting lugs, and mounting hole is provided in the connecting lugs.
It further limits, both sides are respectively provided with sealing strip on the inside of described two anchor ears.
It further limits, the inside side of connecting lugs is pasted with gasket.
It further limits, the sealing strip is integrally formed with gasket.
Using the utility model of above-mentioned technical proposal, is fastened by two semicircle anchor ears, pipeline leakage point is wrapped up
It covers, can pipeline leakage point be subjected to temporary sealing；Instruction pipe is made of lower tube body and upper tube body, and lower tube body is by being inserted within outer
In anchor ear；After two anchor ears fasten, two compositions form circular passage and are connected to lower tube body, as pipeline leakage point air leakage increases
Greatly, the air pressure in groove will incrementally increase, thus by push floating diaphragm plate to upper tube body upper end move, due to floating diaphragm plate with it is upper
Inboard wall of tube body airtight connection, upper tube body, which is located at last point of floating diaphragm plate, will form confined space, and floating diaphragm plate moves after the meeting
The air in the space will be compressed, can speculate that the gas of pipeline leakage point leaks pressure according to the amount of movement of floating diaphragm plate
Power；Setting connecting lugs facilitate two anchor ears to be assembled；Sealing strip can be arranged in both sides on the inside of anchor ear, improve anchor ear and detection
Air-tightness between pipeline；Connecting lugs think that interior side war body has gasket, further increase after two anchor ears fasten with detection
Air-tightness between pipeline；Sealing strip is integrally formed with gasket, further reduces seam, improves air-tightness.
The utility model compared with prior art, it is simple and reasonable, can to natural gas line leak electricity carry out temporary cover
And leakage air pressure is detected.
