Description

Valve testing device
Technical Field
The utility model relates to a relevant technical field of pipeline accessory especially relates to a valve testing arrangement.
Background
When the existing valve is used for pressure testing, the pressure testing is generally completed manually, a mechanical pressure gauge is arranged on a pipeline, then a water pump is started, a frequency converter is manually adjusted, whether a flow counting value is a required value or not is observed, the process needs to be repeatedly adjusted until the ideal state is reached, and the operation is complex. The pressure difference is manually calculated by manually observing the upstream and downstream pressure and flow velocity, and the precision is lower.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, provide a valve testing arrangement, through setting up pressure sensor real-time to pipeline pressure monitoring, the water supply electricity of adjustment intake pump reaches the effective test to the valve parameter.
The utility model adopts the technical proposal that:
the utility model provides a valve testing arrangement, characterized by, includes test valve and the control unit, and the inlet tube of test valve front end and the outlet pipe of rear end set up first pressure sensor on the inlet tube that is close to test valve, set up second pressure sensor on the outlet pipe that is close to test valve, first pressure sensor and second pressure sensor are connected to the control unit, the intake pump on the inlet tube is connected to the control unit, the flow of intake pump is adjusted according to first pressure sensor and second pressure sensor's pressure feedback to the control unit.
Further, still set up the third pressure sensor on the valve, the third pressure sensor also is connected to the control unit, the control unit still controls the intake pump according to the feedback of third pressure sensor.
Furthermore, a butterfly valve is arranged between the water inlet pump of the water inlet pipe and the test valve.
Further, a backflow preventer and a filter are arranged at one end of the butterfly valve.
Further, a flowmeter is arranged on the water outlet pipe.
The utility model has the advantages that:
(1) the automatic monitoring function, the remote control function and the intelligent analysis system can be realized, the measurement precision is high, and the reading is convenient;
(2) the flow rate and the pressure can be automatically monitored, the differential pressure and the water loss can be automatically calculated, the pressure fluctuation can be captured in real time, and the remote alarm prompt can be realized.

Detailed Description
The following describes in detail a specific embodiment of the valve testing device of the present invention with reference to the accompanying drawings.
Referring to fig. 1, the valve testing device is installed on a testing apparatus, and the testing apparatus includes a water tank 1, a water inlet pipe 2, a water outlet pipe 3, and various necessary pipe fittings, a water inlet pump, and the like. A butterfly valve 6 is arranged between the water inlet pump 4 of the water inlet pipe 2 and the test valve 5. One end of the butterfly valve 6 is provided with a backflow preventer 7 and a filter 8, and the water outlet pipe is provided with a flowmeter 9.
The above-mentioned test component is the conventional part among the test valve test process the utility model discloses in expand, see figure 2, set up the control unit among the testing arrangement, set up first pressure sensor 10 on the inlet tube that is close to the test valve front end, set up second pressure sensor 11 on the outlet pipe that is close to the test valve, still set up third pressure sensor 12 on the valve, first pressure sensor 10, second pressure sensor 11 and third pressure sensor 12 all are connected to the control unit, the intake pump on the inlet tube is connected to the control unit, the control unit is according to first pressure sensor 10, the flow of intake pump is adjusted to the pressure feedback of second pressure sensor 11 and third pressure sensor 12. The data of the flowmeter can also enter the control unit, and the control unit automatically calculates the performance parameters of the valve to be measured according to the information.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
