7 side of valve and the pressure tappings 2 of screwing are described to screw 7 other side of valve and the pressure by flanged joint
Pipeline 9 by flanged joint, when surveying pressure described in screw valve 7 and be shown in a fully open operation.
The end cap 8 is in 9 right side of pressure pipeline, and the end cap 8 is connected through a screw thread to be connected with the pressure pipeline 9
It connects.
9 top of pressure pipeline is equipped with the pressure-measuring pipe 11 connected with thread forms, and installs the dedusting additional in junction
Strainer 3, the gasket 10 are placed in 3 top of dedusting strainer, and the pressure-measuring pipe 11, which is connected through a screw thread, compresses the gasket 10
To guarantee sealing, pressure measuring unit 6 is installed above the pressure-measuring pipe 11.
The air pipeline 4 is connect by welding with the pressure-measuring pipe 11, installs the control on 4 top of air pipeline
Valve 5 processed controls compressed air require and pressure.
It is compared with existing pressure obtaning device, the utility model has the following advantages that.
1, a kind of high pressure dust gas pressure obtaning device of the utility model screws valve 7 by closing, and opens simultaneously and air hose
The control valve 5 that road 4 connects, and it is passed through compressed air, dedusting strainer 3 and pressure pipeline 9 are effectively purged, dedusting is removed
The dust adhered on strainer 3, and accumulation of the dust in pressure pipeline 9 will not be made there are dead angle and then form blocking.
2, a kind of high pressure dust gas pressure obtaning device of the utility model is filtered by the way that dedusting is arranged in 6 lower space of pressure measuring unit
Net 3 prevents dust from entering pressure measuring unit 6, avoids pressure gauge that from cannot normally surveying pressure.
