Problems solved by technology

There is a valve and valve flow measurement method for real-time monitoring of gas flow. By measuring the pressure before and after the valve and the temperature in front of the valve, the valve flow value is calculated according to the functional relationship between pressure difference, temperature and valve flow. The flow measurement accuracy is high, but the valve inside The temperature and pressure information of the working medium is obtained by temperature and pressure sensors respectively, and the integration of the measurement system is low. At the same time, the temperature and pressure measurement points in front of the valve are not at the same location, and the temperature parameters behind the valve are not introduced in the flow calculation, which will affect the flow rate. The calculation accuracy has a certain influence

Abstract

The invention discloses a flow measurement method and system for a four-spool valve port independent control valve. The system comprises temperature and pressure sensors, wherein the temperature and pressure sensors are respectively disposed at the front ends and the rear ends of four valve ports of a four-spool valve port independent control valve and are used for transmitting oil pressure and oil temperature data of each valve port to a flow calculation module; and the flow calculation module calculates a flow value of each valve port of the four-spool valve port independent control valve by using the oil pressure and oil temperature data of each valve port. The measurement method is high in accuracy, convenient and efficient.

Description

technical field [0001] The invention belongs to the technical field of hydraulic reversing valves, and in particular relates to a flow measurement method and system for a four-spool valve port independent control valve. Background technique [0002] The hydraulic reversing valve is the core control element of the hydraulic system. Accurate flow measurement of the hydraulic reversing valve is the prerequisite for realizing high-precision control of the hydraulic system. There is a valve and valve flow measurement method for real-time monitoring of gas flow. By measuring the pressure before and after the valve and the temperature in front of the valve, the valve flow value is calculated according to the functional relationship between pressure difference, temperature and valve flow. The flow measurement accuracy is high, but the valve inside The temperature and pressure information of the working medium is obtained by temperature and pressure sensors respectively, and the inte...
