Automatic test method and system of Venturi air valve

Abstract

The invention provides an automatic test method and system of a Venturi air valve. The automatic test system is composed of a blast device and a test execution machine. The blast device is in a butt joint relationship with a to-be-tested Venturi air valve. The test execution machine consists of a main control module, a data / control interface, a display screen, a storage body, and an input operation accessory, wherein the data / control interface, the display screen, the storage body, and the input operation accessory are connected with the main control module. The data / control interface is connected with the blast device and the Venturi air valve. Besides, the automatic test method includes: a plurality of travel record points in the full course of a to-be-tested Venturi air valve are set, the Venturi air valve is operated and real-time blast capacity data are obtained at arrival at the travel record points, and a current travel record point is associated with the real-time blast capacity data; and the Venturi air valve is operated based on a plurality of set blast capacity values, a real-time travel position is obtained at a current blast capacity value, and the real-time travel position is compared with the travel record point to calculate an error value.

Description

technical field [0001] The invention relates to an automatic testing method and system for a Venturi damper. Background technique [0002] The Venturi valve is a device based on the Venturi effect. It combines a mechanical pressure-independent regulator and a high-speed airflow controller to achieve high-precision control and adjustment of the fluid flow in the channel. It is often used in certain requirements. Negative pressure biological products production plant, toxic and harmful, chemical laboratory and biosafety laboratory and other places. The existing Venturi valve action accuracy test is done manually, which not only has low efficiency and high false detection rate, but also cannot achieve high test accuracy, and has high professional requirements for technicians; It is very difficult to test a large number of products, and it is difficult to generate a full test data record, which makes it difficult for manufacturers to analyze product quality problems.
