Abstract

A test platform for an automatic flushing valve is described. It includes a fluid source, weighing parts, a bracket, a diverter and several driplines. The driplines are parallel to each other and are evenly arranged in an array in a circumferential direction of the diverter. Emitters are installed on each of the driplines; one end of each driplines is fixed to the diverter, which is connected to the fluid source to feed fluid into the driplines. The diverter is pivotally connected to the bracket, so that the diverter and the driplines can pivot relative to the bracket; the other end of each driplines is used to install automatic flushing valves. Weighing parts are installed below the automatic flushing valves to measure the solution flowing out of the automatic flushing valves, and other weighing parts are installed below the driplines to measure solution flowing out of the emitters.

First claim

What is claimed is:

1. A test platform for testing at least one automatic flushing valve, comprising: a fluid source, a plurality of first weighing parts, a plurality of second weighing parts, a bracket, a diverter, and a plurality of driplines, wherein
the driplines are parallel to each other and the driplines are evenly arranged in an array in a circumferential direction of the diverter;
a plurality of emitters are provided on each of the driplines;
one end of each of the driplines is fixed to the diverter;
the diverter is connected to the fluid source to feed a solution into the driplines through the diverter, the emitters allow the solution to flow out of corresponding driplines;
the diverter is pivotally supported by to the bracket, so that the diverter and the driplines can pivot relative to the bracket;
the other end of each of the driplines is configured to install the automatic flushing valve; and
each of the plurality of first weighing parts is provided below each of the other ends of the driplines to which the at least one automatic flushing valve is to be installed to monitor a mass of the solution flowing out of the corresponding automatic flushing valve that is installed; and
the plurality of second weighing parts are installed below the driplines to monitor a mass of the solution flowing out of the emitters.

2. The test platform according to claim 1 , further comprising: a horizontal centrifugal pump and a return tank, the return tank is configured to receive the solution flowing out of the emitters, the fluid source comprises a water storage tank, the water storage tank and the return tank are connected through the horizontal centrifugal pump to feed the solution in the return tank into the water storage tank through the horizontal centrifugal pump.

3. The test platform according to claim 2 , further comprising: a water replenishment solution tank, a sand replenishment solution tank and a mixer, the mixer is installed in the water storage tank to stir the solution in the water storage tank, and both the sand replenishment solution tank and the water replenishment solution tank are communicated with the water storage tank.

4. The test platform according to claim 3 , wherein the sand replenishment solution tank and the water storage tank are connected through a sand replenishment pipeline, the water replenishment solution tank and the water storage tank are connected through a water replenishment pipeline, the water replenishment pipeline and the sand replenishment pipeline are respectively equipped with a water replenishment solenoid valve and a sand replenishment solenoid valve, and both the water replenishment solenoid valve and the sand replenishment solenoid valve are electrically connected to a computer.

5. The test platform according to claim 3 , further comprising a turbidity meter connected in communication with a computer, and the turbidity meter is fixedly installed on an inner wall of the water storage tank to monitor a sediment concentration of each layer in the water storage tank in real time.

6. The test platform according to claim 1 , further comprising a timer connected in communication with a computer, and the first weighing parts are weighting sensors connected in communication with the computer.

7. The test platform according to claim 1 , further comprising a connecting rod and a first support ring, the connecting rod is arranged parallel to the driplines, the driplines are evenly distributed around the connecting rod, the first support ring is sleeved and fixed on the connecting rod, the driplines are fixed to the connecting rod through the first support ring, and one end of the connecting rod is fixedly connected to a center point of the diverter.

8. The test platform valve according to claim 7 , wherein the bracket further comprises a second support ring, at least one valve loader and a support rod, wherein the second support ring is sleeved on the connecting rod, the at least one valve loader is installed on the second support ring, each valve loader is arranged to sleeve on the corresponding automatic flushing valve to be installed, and a pipeline for feeding the solution to a corresponding one of the plurality of first weighing parts is installed on each valve loader.

9. The test platform according to claim 7 , wherein the bracket further comprises a second support ring, a support rod, at least one valve loader, and at least one liquid collection bottle, wherein the second support ring is sleeved on the connecting rod, the at least one valve loader is installed on the second support ring, and each valve loader is arranged to sleeve on the corresponding automatic flushing valve to be installed, and each liquid collection bottle is installed on each corresponding valve loader.

10. The test platform according to claim 9 , wherein each of the plurality of first weighing parts is installed in the corresponding liquid collection bottle to monitor a flush water volume and a flush duration; and/or, a sound sensor is installed on the second support ring, and the sound sensor is connected in communication with a computer to monitor and record a start time point and an end time point of a water spray sound when the automatic flushing valve flushes, then calculate a flush duration.
