It is fixed；The flexible pipe body includes bellows, and the outside of the bellows is coated with PE protective layers；The pressure measurement interface component packet
It includes and takes over, the middle part taken over is connected with valve seat, and the valve seat is connected respectively with spool and blanking cover, described one end taken over
It is socketed with nut.
Further, aforementioned gas meter, flow meter pressure measurement connection flexible pipe, the both ends of bellows connect respectively with nipple and pressure measurement
Mouth components welding forms；The PE protective layers are adsorbed in bellows surface by way of pyrocondensation.It can be by this kind of structure
The leakproofness of hose is improved to one step, ensures safety.Korrosionsmedium can be effectively prevent to invade flexible pipe body internal layer simultaneously,
Bellows is caused to corrode, to ensure the long-time service of hose.
Further, aforementioned gas meter, flow meter pressure measurement connection flexible pipe, takes over one end and is connected with bellows, the other end is socketed with
Nut, nut can circumferentially be freely rotated along bellows.And the seam allowance that axial limiting is formed to nut is additionally provided on this port.Institute
Valve seat is stated to be welded to connect with taking over；The spool is connected with valve seat screw thread, and spool is formed after sealing with valve seat with valve seat end face
On the basis of.
Further, aforementioned gas meter, flow meter pressure measurement connection flexible pipe, blanking cover inside are close with valve seat end face plane equipped with gasket
Envelope.Connection flexible pipe is at least there are two sealed structures, and spool forms first of sealing with valve seat, and valve seat forms second with blanking cover
Sealing, use is multiple-sealed, can reduce with gas risk.
Further, aforementioned gas meter, flow meter pressure measurement connection flexible pipe, pressure measurement interface component are connected directly with pressure instrumentation.It is convenient
It uses, simple operation.
The utility model is rational in infrastructure, easy to use.Pressure measurement interface component can be passed through in the case where pipeline is fully connected
It is connected with pressure instrumentation.Can conveniently signal piping whether leak, and it is convenient to detect the pressure value in gas pipeline
Pressure is adjusted.Be not only convenient for construction team in project installation, stop renaturation gas supply and multiple stages such as zero consumption inspection are detected,
And usually using self-test at any time convenient for user.
Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the flexible pipe body structure diagram of the utility model.
