Title:
CONSTANT-PRESSURE EXPERIMENT BASED DEVICE AND METHOD FOR MEASURING VALVE LEAKAGE OF PRESSURE BALANCE VALVE
Document Type and Number:
WIPO Patent Application WO/2023/115841
Kind Code:
A1
Abstract:
A constant-pressure experiment based device and method for measuring a valve leakage of a pressure balance valve. The device comprises a valve to be subjected to measurement (1), a gas storage tank (2), a mass block working pipeline (9), a mass block (10), a stop valve (15) and a gas compressor (16), wherein a gas flow inlet of the valve to be subjected to measurement (1) is connected to the gas storage tank (2) by means of a gas conveying pipeline (19); the gas compressor (16) is connected to the gas storage tank (2) by means of the gas conveying pipeline (19); the other gas flow outlet of the gas storage tank (2) is connected to a gas flow inlet of the gas conveying pipeline (19) and is fixed by means of bolts; a gas flow outlet of the gas conveying pipeline (19) is connected to the mass block working pipeline (9); the mass block (10) is in gastight connection with the mass block working pipeline (9); and the mass block (10) can freely move in the mass block working pipeline (9) according to the magnitude of gas pressure in the mass block working pipeline (9). Leakages of a valve under different standard measurement pressures can be measured; the weight of the mass block (10) can be further reduced; a measurement problem occurring when there is a micro leakage in the valve is solved, thereby solving the problem of low precision of leakage measurement; and the application range is wide.
