進(jìn)口調(diào)節(jié)閥—美國威盾VTON品牌,又名控制閥,英文名:control valve,調(diào)節(jié)閥常用分類:氣動調(diào)節(jié)閥,電動調(diào)節(jié)閥,液動調(diào)節(jié)閥,自力式調(diào)節(jié)閥。在工業(yè)自動化過程控制領(lǐng)域中,通過接受調(diào)節(jié)控制單元輸出的控制信號,借助動力操作去改變介質(zhì)流量、壓力、溫度、液位等工藝參數(shù)的zui終控制元件。一般由執(zhí)行機(jī)構(gòu)和閥門組成。如果按行程特點(diǎn),調(diào)節(jié)閥可分為直行程和角行程;按其所配執(zhí)行機(jī)構(gòu)使用的動力,按其功能和特性分為線性特性,等百分比特性及拋物線特性三種。調(diào)節(jié)閥適用于空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品等介質(zhì)。Regulating valve, control valve, control valve commonly used classification: pneumatic control valve, electric control valve, hydraulic control valve, self operated regulating valve. Process control in industrial automation field, by adjusting the control unit outputs the control signal, the final control element with the power to change the media flow, pressure, temperature, level and other parameters. Generally by the actuator and valve components. If press trip characteristics, control valve can be divided into linear and angular travel itinerary; by its executive agencies use the power, according to their functions and features into linear characteristics, such as the percentage of properties and characteristics of the three parabolic. Control valve for air, water, steam, all kinds of corrosive media, mud, oil and other media.
