- 進(jìn)口高壓電動調(diào)節(jié)閥 進(jìn)口高壓電動調(diào)節(jié)閥概述： 高壓電動調(diào)節(jié)閥是一種壓力平衡式的調(diào)節(jié)閥。接受調(diào)節(jié)儀表來的直流電流信號，改變被調(diào)介質(zhì)流量，使被控電動單座調(diào)節(jié)閥(14張)工藝參數(shù)保持在給定值。廣泛應(yīng)用于電力、冶金、化工、石油、輕紡、制藥、造紙等工業(yè)部門的生產(chǎn)自動化控制。 Imported high pressure electric regulator overview: High voltage electric control valve is a kind of pressure balance type regulator. Accept adjusting instruments to dc current signal, change the modulated medium flow, make charged electric single-seat regulating valve (14) process parameters in a given value. Widely used in electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors of production automation control. 一、進(jìn)口高壓電動調(diào)節(jié)閥產(chǎn)品特征分類： 流通能力Cv是選擇調(diào)節(jié)閥的主要參數(shù)之一，調(diào)節(jié)閥的流通能力的定義為：當(dāng)調(diào)節(jié)閥全開時，閥兩端壓差為0.1MPa，流體密度為1g/cm3時，每小時流徑調(diào)節(jié)閥的流量數(shù)，稱為流通能力，也稱流量系數(shù)，以Cv表示，單位為t/h，液體的Cv值按下式計算。根據(jù)流通能力Cv值大小查表，就可以確定調(diào)節(jié)閥的公稱通徑DN。調(diào)節(jié)閥的流量特性，是在閥兩端壓差保持恒定的條件下，介質(zhì)流經(jīng)調(diào)節(jié)閥的相對流量與它的開度之間關(guān)系。調(diào)節(jié)閥的流量特性有線性特性，等百分比特性及拋物線特性三種。等百分比特性的相對行程和相對流量不成直線關(guān)系，在行程的每一點(diǎn)上單位行程變化所引起的流量的變化與此點(diǎn)的流量成正比，流量變化的百分比是相等的。所以它的優(yōu)點(diǎn)是流量小時，流量變化小，流量大時，則流量變化大，也就是在不同開度上，具有相同的調(diào)節(jié)精度。線性特性的相對行程和相對流量成直線關(guān)系。單位行程的變化所引起的流量變化是不變的。流量大時，流量相對值變化小，流量小時，則流量相對值變化大。 Flow capacity Cv is one of the most important parameters to choose the regulating valve, regulating valve of flow capacity is defined as: when the control valve fully open, on both ends of the valve differential pressure is 0.1 MPa, the fluid density is 1 g/cm3, the regulator on the number of traffic flow diameter per hour, called flow capacity, also known as the flow coefficient, expressed as a Cv, unit for t/h, Cv value of the liquid press type calculation. According to the flow capacity Cv value look-up table size, you can determine the nominal size of the regulating valve DN. Regulating valve flow characteristic, it is on both ends of the valve differential pressure under the condition of constant, medium flows through the regulator of the relation between relative flow and its opening. Regulating valve the flow characteristic of linear features, such as percentage and parabolic characteristics of three. Percentage characteristics such as relative trip and no linear relationship between relative flow in the process of every point unit running change caused by the flow of change is proportional to the flow of this point, the percentage of the flow rate change is equal. So it has the advantage of traffic hours, changing flow is small, large flow, the flow rate change is big, is also on the different opening, has the same accuracy. Linear characteristic of relative stroke and the relative flow into a linear relationship. Unit trip caused by the changes in the flow rate change is constant. Large flow, the flow relative changes little, traffic hours, flow relative change is big. 二、進(jìn)口高壓電動調(diào)節(jié)閥參數(shù)分類 連接形式分類：法蘭、焊接 尺寸范圍：DN15～DN400 壓力等級：1.0～32MPa 殼體材料：碳鋼、不銹鋼 適用介質(zhì)：水、氣體、液體、石油、蒸汽? 操作方式：電動 技術(shù)參數(shù) 固有流量特性:直線、等百分比 工作溫度t(℃):-20～200、-40～250、-40～450、-60～450 信號范圍(DC):0～10mA、4～20mA、1～5V、0～10V 電源電壓:220V、50Hz 作用方式:電開式(K)、電關(guān)式(B) Second, imported high pressure electric regulator parameter classification Connection form classification: flange, welding Size range: DN15 ~ DN400 Pressure rating: 1.0 ~ 32 mpa Shell material: carbon steel, stainless steel Applicable medium: water, gas, liquid, oil, steam Mode of operation: electric parameters The intrinsic flow feature: straight line, such as percentage Working temperature t (℃) : - 20 ~, 40 ~ 250 -, 200-40 ~ 450, 60 ~ 450 Signal (DC) : the range is 0 ~ 10 ma, 4 ~ 20 ma, 1 ~ 5 v, 0 ~ 10 v Power supply voltage: 220 v, 50 hz Role: electric open (K), electric type (B) VTON（威盾）閥門國際有限公司 代理公司：深圳名閥進(jìn)出口貿(mào)易有限公司 聯(lián)系人：黃生 電話：0755-29172950 傳真：0755-29172950 使用業(yè)績： 深圳地鐵1號線（羅寶線）Shenzhen metro line 1(luobao line) 深圳地鐵2號線（蛇口線）Shenzhen metro line 2 (shekou line) 深圳地鐵3號線（龍崗線）Shenzhen metro line 3 (longgang line) 深圳地鐵4號線（龍華線）Shenzhen metro line 4(longhua line) 深圳地鐵5號線（環(huán)中線）Shenzhen metro line 5(huanzhong line)
