Description

Throttling device testing device

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of check out test set, especially, relate to a testboard of throttling capillary for refrigerating plant.

[ background of the invention ]

In small refrigeration units, capillary tubes are still commonly used throttling devices. In the actual working process of the refrigerating device, the medium flow in the capillary tube is two-phase flow blockage, a theoretical calculation model is complex, and usually, a sample is firstly manufactured through a test bench according to theoretical pressure difference and flow, and then is installed in a prototype for performance test.

The traditional test bench generally adopts a mechanical pressure gauge to collect the front and back pressure of a capillary to be tested, and adopts a mechanical gas flowmeter to measure the gas flow. The disadvantage of this test bench is that it is usually necessary to manually adjust the flow and to manually record the pressure-flow data, and the degree of intelligence and automation is not high.

Therefore, there is a need to provide a new testing device for a throttle device to solve the above problems.

[ Utility model ] content

A primary object of the present invention is to provide a flow regulator testing device, which can automatically adjust and set flow, and automatically collect inlet and outlet pressure data, and store the data in a computer, so as to improve the efficiency and intelligence of testing operation.

The utility model discloses a following technical scheme realizes above-mentioned purpose: a throttling device testing device comprises an air inlet pipe communicated with one connecting end of a tested piece, an air outlet pipe communicated with the other connecting end of the tested piece and a controller, wherein a first stop valve, a first pressure sensor and a flow regulating valve which are electrically connected with the controller are arranged on the air inlet pipe, and a second stop valve, a second pressure sensor and a flow sensor which are electrically connected with the controller are arranged on the air outlet pipe.

Furthermore, a data storage module and a communication module are arranged in the controller, so that data can be stored and transmitted to an upper computer.

Furthermore, the first stop valve and the second stop valve are close to the inlet and outlet ends of the tested piece, are controlled by a pneumatic or electric actuator, and are switched on and off at the controller end.

Further, the flow regulating valve is controlled by a pneumatic or electric actuator.

Further, the first pressure sensor and the second pressure sensor are digital pressure sensors.

Further, the flow sensor is an electronic flow sensor.

Furthermore, the other end of the air inlet pipe is communicated with the air source inlet, and the other end of the air outlet pipe is communicated with the air source outlet.

Compared with the prior art, the utility model relates to a throttling arrangement testing arrangement's beneficial effect lies in: the automation degree is high, and the labor intensity of workers is reduced; in addition, the intelligent degree is high, and convenient data processing and automatic test report generation are facilitated.
