Technical Field
The utility model belongs to the technical field of drainage measuring device, concretely relates to simple and easy practical gravity drainage flow measurement device.
Background
In order to calculate the cost of sewage treatment or save water, the amount of water to be discharged needs to be measured frequently. Drainage is often done in two ways: one is gravity drainage, namely a drainage pipe channel is provided with a slope in the horizontal direction, and sewage flows along the slope of the pipe channel by virtue of gravity to be drained; the other is pressure drainage, namely, a pump is used for supplying energy to liquid, and sewage is discharged through pipeline transportation. The gravity drainage has the biggest characteristic that the drainage flow rate is large in change from zero to a normal value to a maximum value and is continuously and repeatedly changed, so that a drainage pipe duct cannot be filled with the cross section frequently, and the measurement principle of a common flowmeter requires that fluid passing through the flowmeter must be filled with the cross section of the flowmeter, so that the accurate measurement is possible.
SUMMERY OF THE UTILITY MODEL
To the above problem, an object of the utility model is to provide a simple and easy practical gravity drainage flow measurement device.
In order to achieve the purpose, the following technical scheme is provided:
the utility model provides a simple and easy practical gravity drainage flow measurement device, includes flow measurement pipeline and flowmeter, and flow measurement pipeline's one end is used for connecting into water drainage pipe or the drainage canal of intaking, and the other end is used for connecting out water drainage pipe or the drainage canal of intaking, and flow measurement pipeline's pipeline top is less than the bottom of business turn over water drainage pipe or business turn over water drainage canal, and the flowmeter is installed on flow measurement pipeline.
Furthermore, a filter well is arranged at the joint of the water inlet drainage pipeline or the water inlet drainage channel and the flow measuring pipeline, an inspection well is arranged at the joint of the water outlet drainage pipeline or the water outlet drainage channel and the flow measuring pipeline, and a flow meter well is arranged above the flow measuring pipeline provided with the flow meter.
Furthermore, the flow measuring pipeline comprises a first straight pipe section and a second straight pipe section, the first straight pipe section is located between the flowmeter and the filter well, the second straight pipe section is located between the flowmeter and the inspection well, and the inner diameters of the first straight pipe section and the second straight pipe section are the same.
Furthermore, the length of the first straight pipe section is 5-10 times of the inner diameter of the first straight pipe section, the length of the second straight pipe section is 3-5 times of the inner diameter of the second straight pipe section, and certain buffering time is given to water flow in the pipeline.
Further, the bottom in the filter well is provided with a filter basket.
Furthermore, the ratio of the inner diameter of the flow measuring pipeline to the inner diameter of the water inlet drainage pipeline or the water inlet drainage channel is 0.9-1, and the ratio of the inner diameter of the flow measuring pipeline to the inner diameter of the water outlet drainage pipeline or the water outlet drainage channel is 0.9-1.
Further, the flow measuring pipeline is arranged in parallel with the horizontal plane.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model adopts the method of measuring flow rate by a common flowmeter of a water supply pipeline, aiming at the problem that a gravity drainage pipe canal can not be filled with cross sections, a section of pipeline which can ensure to be filled all the time is arranged on the conventional gravity drainage pipe canal, and a water filter is arranged to ensure the normal use of the flowmeter under the condition that sewage can have impurities and the like; the device can be used for measuring the flow on all drain pipe networks by adopting a conventional feed water flow measuring method, and has the characteristics of simple principle, convenience and practicability.
