Document Type and Number:
WIPO Patent Application WO/2019/184003
Kind Code:
A1
Abstract:
A device for detecting the working state of a check valve. The device comprises a mechanical part and a data acquisition part. The mechanical part is provided with a liquid inlet (17), a liquid outlet (22), a valve element (20), a valve seat (19), a valve body (21), a valve cavity (23), a rubber damping pad (18), a spring (24), an indicating rod (16), a valve element travel cavity (27), a cover plate (15), a base (25), and a protective cover (28); the data acquisition part is provided with a temperature detection unit (1), a vibration detection unit (2), a pressure detection unit (3), an anti-disassembly detection unit (4), a valve element position detection unit (5), a wireless transmission unit (9), a data storage unit (8), and a data display unit (6) which are connected to a signal processing unit (7) separately and provided with independent power supply modules (10). The advantages are that: safety and reliability are achieved, acquired data can be displayed in real time on site and can be wirelessly transmitted; workers can check the data in real time, on-site problem responding speed is increased, energy waste is avoided, and equipment abrasion is reduced. An anti-theft function is also achieved, a correction method is given to a formula for calculating the liquid production capacity according to the check valve, and the calculation precision of the liquid production capacity is greatly improved.
