The existing flow control valves (FCV) generally have problems with low flow control
accuracy, high-pressure loss, and difficult flow fine-tuning. Therefore, this paper proposes a …

A pressure-compensated valve (PC valve) is a type of flow control device that is a
combination of a control orifice and a compensator (often called a hydrostat). The …

Heavy load equipment, such as tractors, shovels, cranes, airplanes, etc, often employ fluid
power (ie hydraulic) systems to control their loads by way of valve adjustment in a pump …

压力补偿控制流量方法, 应用广泛, 控制可靠, 但受机械结构限定, 存在控制精度低, 功能单一,
流量范围受限等不足, 难以适应主机智能化发展. 为此, 提出基于主动压差调控的变增益流量控制 …

The constant pressure difference regulating mechanism is widely used in aeroengine fuel
servo metering systems, and it almost decides the metering precision. However, the design …

提出一种等压差活门的正向频域设计方法, 内容包括: 基于线性系统理论, 推导了等压差活门的
状态空间模型; 基于频域分析方法, 建立了等压差活门结构参数与系统性能的显式关系 …

The traditional pressure-compensated multi-way valve generally have the problems of low
flow control accuracy, limited flow range, and difficult flow fine-tuning. Therefore, this paper …

The closed-loop constant pressure drop control valve is widely used in aero-engine fuel
servo metering systems. However, the available constant pressure drop control valve cannot …

The flow-control method of pressure compensation is widely used and reliable. But limited
by the mechanical structure, there are some shortcomings, such as low control accuracy …

The use of remote sensing technology has made it possible for the non-contact
measurement of soil moisture content (SMC). Many remote sensing techniques can be used …
