Detailed Description
Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
In the pipeline test, the tested detector enters from one end of the analog circulation pipeline, passes through the analog circulation pipeline under the pushing of liquid, and is recovered from the other end of the analog circulation pipeline, and the process is called a receiving and dispatching ball. The detector enters the analog circulation pipeline to be called as a ball serving, and the detector is recovered from the analog circulation pipeline to be called as a ball receiving.
Example 1
Referring to fig. 1, a preferred embodiment of the present invention includes a simulation circulation pipeline 100, a power switching valve set 200, a pump set 300, a liquid storage tank 400, a filter tank 500, and a hydraulic hose 600. They are combined together to form a liquid circulation system.
The simulation circulation line 100, also called a ball receiving and dispatching cylinder, is a test line with two ports for simulating an actual pipeline. The power switching valve set 200 has four ports, wherein a first port 201 is connected with one end of the pump set 300, and then is connected to the liquid storage tank 400 by the other end of the pump set 300; the second port 202 is connected with the filter tank 500 and then connected to the liquid storage tank 400 through the filter tank 500; the third port 203 and the fourth port 204 are connected to both ends of the analog circulation line 100 through hydraulic hoses 600, respectively.
Inside the power switching valve group 200, a pressure gauge 205 for measuring the pressure of the liquid in the simulated circulation pipeline 100 and an overflow ball valve 206 for adjusting the flow rate of the liquid in the simulated circulation pipeline 100 are provided at the first port 201. The overflow ball valve 206 serves as a bypass branch, one end of which is connected to the output line of the pump stack 300 and the other end of which is connected to the reservoir 400. Inside the power switching valve block 200, at the second port 202, a flow meter 207 is provided for measuring the flow rate of the liquid in the simulated circulation line 100.
The power switching valve set 200 can switch the flow direction of the liquid in the simulated circulation pipeline 100 without detaching the pipeline connection, and has two working modes: in the first mode of operation, fluid flows from the third port 203 and into the fourth port 204; in the second mode of operation, fluid flows from the fourth port 204 and into the third port 203. The switching of the working mode is controlled by a first valve group 208 and a second valve group 209 in the power switching valve group 200: when the power switching valve set 200 works in the first working mode, the first valve set 208 is opened, and the second valve set 209 is closed; when the power switching valve set 200 operates in the second operating mode, the second valve set 209 is open and the first valve set 208 is closed. The first valve set 208 and the second valve set 209 each contain 2 DN100 ball valves.
In the test procedure of simulating the ball receiving and sending, the pressure gauge 205 is used to monitor the pressure of the liquid in the simulated circulation line 100, and ensure the consistency with the actual operation. When the detected detector enters from the third port 203 and exits from the fourth port 204, the power switching valve set 200 is configured to be in the first operating mode, i.e., the first valve set 208 is opened and the second valve set 209 is closed. The flow direction is from the third port 203 to the fourth port 204, and the detected sensor flows from the right pipeline to the left along the analog circulation pipeline 100. During which, if the speed of the detector under test needs to be adjusted, overflow ball valve 206 can be adjusted: the speed of the detected detector is reduced when the opening is large, and the speed of the detected detector is fastest when the opening is closed. The speed at which the sensor under test is operating in the pipeline can be converted from the reading of the flow meter 207.
When the detected detector enters from the fourth port 204 and exits from the third port 203, the power switching valve set 200 is configured to be in the first operating mode, i.e., the second valve set 209 is opened and the first valve set 208 is closed. The flow direction is now along the fourth port 204 to the third port 203, and the detector under test follows the simulated circulation line 100 from the left line to the right. The same applies to the speed regulation.
In this embodiment, liquid is used cyclically, so set up rose box 500 and filter the liquid that flows out, avoid the filth secondary entering pipeline in the pipeline.
The power device of the embodiment is particularly suitable for the detectors which can run in the forward and reverse directions, so that when the detected detector reaches the end point, the pipeline does not need to be disassembled for replacement of the inlet and the outlet, the power device can run in the reverse direction, and the next test can be started immediately. Because of the long dummy line, once removed, the fluid is lost particularly much, and it takes a long time for the next reverse run to occur.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All equivalent changes and modifications made according to the content of the claims of the present invention shall fall within the technical scope of the present invention.
