Arrange that the pressure measuring unit 10, the pressure-measuring pipe line 9 are vertical arrangement on the pressure-measuring pipe line 9, the survey press fitting
For the installation direction and the pressure-measuring pipe line 9 for setting 10 at 60 degree, the pressure measuring valve 1 is mounted on 9 end of pressure-measuring pipe line.
The equalizer valve 6 is installed on the pressurising pipeline 5, and is opened at the middle part of the pressurising pipeline 5 and the equalizer valve 6
Hole installs the blow line 11 additional, is disposed with the blow down valve 7 and the restriction orifice 8 on the blow line 11.
It is compared with existing gasification ashes lock pressure measuring system, the utility model has the following advantages that.
1, a kind of gasification ashes lock pressure measuring system of the utility model is connect with ash lock 2 obliquely by pressure pipeline 4, is reduced
Accumulation of the dust inside pressure pipeline 4.
2, a kind of gasification ashes lock pressure measuring system of the utility model is connected with pressure-measuring pipe line 9 obliquely by pressure measuring unit 10
It connects, avoids dust and be directly entered pressure measuring unit 10 under gravity, to damage measuring instrumentss, cause people or machine
Erroneous judgement.
3, a kind of gasification ashes lock pressure measuring system of the utility model on blow line 11 by installing restriction orifice 8, drop
Low circulation area increases gas flow rate, enhances the purging effect to pipeline.
Detailed description of the invention
Fig. 1 is the structure chart that a kind of gasification ashes of the utility model lock pressure measuring system.
