Description
Technical field
The utility model relates to a kind of flame-proof type electromagnetic flowmeter, belongs to the colliery and uses the flow measurement technical field.
Background technology
At present, the coal mine down-off is metered into special management control.Because the general industry flow measurement instrument can not adapt to the explosive gas atmosphere under the coal mine, makes the colliery downhole flow measurement can not normally carry out always.
Summary of the invention
The utility model purpose provides a kind of flame-proof type electromagnetic flowmeter; Because the flame proof ability that meter case possessed; Make instrument can carry out flow measurement in the explosive gas atmosphere and control and management under the coal mine safely, solve the problems referred to above that background technology exists.
The utility model solves the technical scheme that its technical matters adopted: a kind of flame-proof type electromagnetic flowmeter; Comprise sensor main body, switch main body chassis lid and switch main body cabinet under casing; Said switch main body chassis lid is connected closed with switch main body cabinet under casing; Sensor main body is connected with the sensor signal cable through the excitatory cable of sensor with switch main body cabinet under casing; Switch main body cabinet under casing is connected with the converter power cable, and switch main body chassis lid and switch main body cabinet under casing are provided with the converter explosion suppresion surface.
Said sensor main body is provided with sensor excited signal thread guide devices and sensor output signal thread guide devices.
Said switch main body cabinet under casing is provided with the excitatory output lead device of converter, transducer signal input lead device and converter power thread guide devices.
Said switch main body chassis lid is provided with converter monitoring display window and converter induction keyboard.
Said converter explosion suppresion surface comprises converter case lid explosion suppresion surface and converter under casing explosion suppresion surface, and the size of converter case lid explosion suppresion surface and converter under casing explosion suppresion surface is length >=12.5mm, width >=8.0mm, Hou Du ≦ 0.15mm.
The beneficial effect of the utility model is: according to the particular surroundings requirement under the coal mine, make the converter shell of flowmeter have flame proof and extinguishing arc ability.When the underground survey environment explosion time that meets accident, make this converter can effectively protect the security of instrument itself, take place with the danger that prevents the related blast of secondary.Because the instrument of the utility model has realized coal mine downhole safety and has measured metering reliably; Solved the difficult problem that pipeline flow is measured under the coal mine for many years; Realize the special management control of coal mine down-off metering; The centralized control that also can the secondary output through instrument realizes mine is for the safety under the coal mine and management provide assurance.
