Abstract
The utility model provides a water tank liquid level measurement device, and belongs to the technical field of liquid level measurement equipment. The water tank liquid level measurement device is used for measuring a liquid level of a water descaling water tank in a wire plant. The water tank liquid level measurement device is composed of a measurement pipeline and a pressure transmitter, wherein the measurement pipeline is horizontally connected to the bottom of the water tank, the pressure transmitter is installed in the measurement pipeline, a signal output end of the pressure transmitter is connected with a signal input end of a programmable controller, and a drainage valve is installed on the lower portion of the measurement pipeline. According to the water tank liquid level measurement device, the pressure transmitter is installed at the bottom of the water descaling water tank, a measured pressure valve is converted into a water tank liquid level actual value, and the purpose of measurement for the liquid level of the water descaling water tank is achieved. The fact that the effect of liquid level measurement is not influenced when turbid circulating water is used in water descaling is guaranteed, cost is lower than the cost produced when clean water is used, and resource waste and equipment failure are reduced. The water tank liquid level measurement device is good in utilization effect and free of overflowing situations, and guarantees the automatic and precise water complement function of the water tank.
Description
Technical field
The utility model relates to a kind of device of measuring water de-scaling high water tank, belongs to the fluid level measuring device technical field.
Background technology
The water de-scaling water tank of wire rolling plants need to carry out level gauging, in order to carry out suitable moisturizing.Existing fluid level measuring gauge adopts magnetic turnover plate type liquid level gauge, its principle is that the float that is magnetic in the liquid level gauge changes lifting with cistern water level, the analog signals that liquid level gauge output changes is thereupon passed to programmable controller, gets the water tank actual liquid level after converting in programmable controller.Owing to use the interior water quality of turbid circulating water water tank bad in the actual production, there are foreign material to cause magnetic float blocking in the liquid level gauge in the water, the output analog signals does not change, actual liquid level raises always during moisturizing, so that the water tank automatic watering does not stop to cause waste, can't realize that automatic water supplement accurately controls, this is the measurement mechanism defective in actual use that adopts magnetic turnover plate type liquid level gauge, is necessary to be improved.
The utility model content
Technical problem to be solved in the utility model provides a kind of high water tank measurement mechanism, this device can be in the turbid circulating water situation Measurement accuracy water level, realize that automatic water supplement accurately controls, reduce the wasting of resources.
The technical scheme that solves the problems of the technologies described above is:
A kind of high water tank measurement mechanism, it is comprised of measuring channel, pressure unit, the measuring channel level connection joint is in the bottom of water tank, and pressure unit is installed in the measuring channel, and the signal output part of pressure unit is connected with the signal input part of programmable controller.
Above-mentioned high water tank measurement mechanism is equipped with sewage draining valve in the bottom of measuring channel.
The beneficial effects of the utility model are:
The utility model is converted to the high water tank actual value at the bottom of water de-scaling water tank setting pressure transmitter with the pressure value that records, and reaches the purpose of Measurement accuracy water de-scaling cistern water level.The utility model has guaranteed can not affect the effect of measuring water level when turbid circulating water is used in the water de-scaling, with respect to using clean circulating water to reduce cost, reduced the wasting of resources and equipment failure.Practical effect of the present utility model is good, and the spilling water situation does not occur again, has guaranteed the automatic accurate water supplement function of water tank.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark is as follows among the figure: water tank 1, measuring channel 2, pressure unit 3, sewage draining valve 4.
Embodiment
Traditional magnetic turnover plate type liquid level gauge is subjected in the water impurity effect larger, in the situation of using turbid circulating water, avoids the bad impact on liquid level gauge of water quality, and measuring exactly that high water tank changes is the purpose of this utility model.
The utility model is comprised of measuring channel 2, pressure unit 3.
Show among the figure, bottom at water tank 1 increases a measuring channel 2 connected horizontally, pressure unit 3 is installed in the measuring channel 2, and the water pressure in the water tank 1 is measured, and the signal output part of pressure unit 3 is connected with the signal input part of programmable controller.In the bottom of measuring channel 2 sewage draining valve 4 is installed, sewage draining valve 4 regularly opens to get rid of the impurity in the measuring channel 2.
The liquid level maximum height of the water tank 1 of an embodiment of the present utility model is 1.7M, and this embodiment selects EJA530A type pressure unit, its maximum working pressure (MWP) 2MPa.
On-the-spot electric wiring connects rear plugged, adjusts pressure unit 3 ranges and site measuring and control instrument range, so that both are complementary; The analog quantity template that increases programmable controller is carried out first hardware configuration, then revise the programmable controller program, the logic control function that adds new pressure unit 3, converse the actual liquid level height according to the measured pressure value of pressure unit 3 and feed back to programmable controller, carry out logic control by programmable controller, 1 moisturizing of realization water tank is controlled automatically.
