Problems solved by technology

[0004] The latest products of dynamic balance electric valves generally adopt the principle of spring mechanical self-reliance, so there are small flow capacity, limited dynamic working pressure difference control range, inflexible application, high starting point of working pressure difference, high overall pressure loss at both ends of the valve, etc. Disadvantages (since DP=DP 1 +DP 2 , in actual use, the pressure of the differential pressure controller must be sacrificed to maintain the differential pressure of the electric control valve, such as DP 1 constant, obviously sacrificing the pressure of the differential pressure controller is also a waste of energy)

Abstract

The present invention relates to an intelligent control implement method of valve and its valve. Said invention is aimed at providing an implement method of intelligent fluid control valve based on high-level calculation and its valve. Said method includes the following steps: setting flow value in intelligent controller, data sampling external signal and comparing it with set value, utilizing APID algorithm to regulate opening of electric valve component so as to implement intelligent control. Said control valve includes valve body and electric valve component placed in said valve body interior, and said electric valve component includes flow sensor, intelligent controller and electric executor, etc.

Description

technical field [0001] The invention relates to a valve intelligent control realization method and a valve. More specifically, the present invention relates to a realization method and valve of an intelligent fluid control valve based on advanced calculation. Background technique [0002] Hydraulic imbalance is common in the water system pipe network. The hydraulic imbalance of the pipe network will easily lead to the waste of system energy and the increase of equipment operation noise. The fluid control valve with advanced intelligent dynamic flow balance function is the solution to the hydraulic balance of complex pipe networks. best means. [0003] The dynamic flow balance electric control valve commonly used at present is essentially a pressure-independent electric valve with mechanical self-operated pressure difference automatic control function. The principle of dynamic balance is relatively simple, that is, integrated or combined dynamic balance electric valve. The ...
