Background
The liquid level measurement of the vinyl chloride spherical tank generally adopts a radar liquid level meter method, but the larger vinyl chloride spherical tank belongs to a secondary serious hazard source, and various measurement modes are required to ensure the accuracy of the measured liquid level. The double-flange liquid level transmitter is commonly used for measuring the liquid level of a vinyl chloride spherical tank, but the phenomenon of inaccurate liquid level measurement is easily caused when the double-flange liquid level transmitter is directly used for measurement, because the distance from a pressure guiding pipe connected with the top of the spherical tank to an upper flange (low-pressure side) of the double-flange pressure transmitter from the top of the spherical tank is too long, the boiling point of vinyl chloride is-13 ℃, the distance is too long, vinyl chloride forms a liquid phase in the pressure guiding pipe, and the liquid-phase vinyl chloride is easily accumulated in a drainage pipe and the upper flange, so that the pressure measured by the upper flange (low-pressure side) of the double-flange pressure transmitter is not the pressure in the spherical tank, the data measured by the upper flange is inaccurate, and the overall data measured by the double-flange pressure transmitter is inaccurate.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can improve measurement accuracy's vinyl chloride spherical tank liquid level measurement device.
In order to achieve the above object, the utility model adopts the following technical scheme: vinyl chloride spherical tank liquid level measurement device includes: spherical tank, two flange pressure transmitter are connected with first pressure pipe in the upper end of spherical tank, and first pressure pipe links to each other with chloroethylene collection device, is connected with the second pressure pipe at the lower extreme of spherical tank, is provided with the drainage tube in the slant on first pressure pipe, and the drainage tube upwards is 30 ~ 60 contained angles with first pressure pipe, and the second pressure pipe links to each other with the lower flange among the two flange pressure transmitter, and the last flange among drainage tube and the two flange pressure transmitter links to each other.
Further, the liquid level measuring device for the vinyl chloride spherical tank comprises: the chloroethylene drainage tank is communicated with the chloroethylene gas tank through a pipeline.
Further, in the aforementioned liquid level measuring device for a vinyl chloride spherical tank, an air pump and a first electromagnetic valve are disposed on the pipeline.
