    • 進(jìn)口電動單座調(diào)節(jié)閥 一、電動單座調(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。 電動平衡籠式調(diào)節(jié)閥控制各種高溫、低溫的高壓流體，是一種壓力平衡式的調(diào)節(jié)閥。閥結(jié)構(gòu)緊湊，有呈S流 線型的通道.DHCB電動平衡籠式調(diào)節(jié)閥，控制各種高溫、低溫的高壓流體，是一種壓力平衡式的氣動調(diào)節(jié)閥。閥結(jié)構(gòu)緊湊，有呈S流線型的通道，還設(shè)有一個改善套筒周圍流體平衡流動的導(dǎo) 流翼，使其壓降損失小，流量大，可調(diào)范圍廣，流量特性精度高，符合IEC534-1-1976 標(biāo)準(zhǔn)。調(diào)節(jié)閥的動態(tài)穩(wěn)定性好，噪音低，空化腐蝕小。調(diào)節(jié)閥的泄漏量符合ANSIB16.1 04標(biāo)準(zhǔn)。 Electric single-seat regulating valve is a kind of pressure balance type regulator. Accept adjusting instruments to dc current signal, change the modulated medium flow, keep accused of process parameters in the given value. Widely used in electric power, metallurgy, chemical industry, petroleum, textile, pharmaceutical, paper and other industrial sectors of production automation control. Electric balance cage valve control all kinds of high temperature and low temperature high pressure fluid, is a kind of pressure balance type regulator. Valve structure is compact, in an s-shaped channel flow lines. DHCB electric balance cage valve, high pressure fluid control all kinds of high temperature, low temperature, is a kind of pressure balance type pneumatic control valve. Valve structure is compact, has S streamlined channel, also has an improved balance flow guide sleeve around fluid flow wing, make its loss of the pressure drop is small, large flow, adjustable range and flow characteristic of high precision, IEC534-1-1976 standard. Regulator of dynamic stability, low noise, small cavitation corrosion. Regulating valve leakage ANSIB16.1 04 standards. 二、主要參數(shù)分類 產(chǎn)品口徑：DN15-1000 公稱壓力：1.6MPA-70MPA 適用溫度：-40°C-600°C 三、電動單座調(diào)節(jié)閥優(yōu)點 電動單座調(diào)節(jié)閥是一個新的自力式調(diào)節(jié)閥種類。相對于手動調(diào)節(jié)閥，它的優(yōu)點是能夠自動調(diào)節(jié);相對于電動調(diào)節(jié)閥，它的優(yōu)點是不需要外部動力。應(yīng)用實踐證明，在閉式水循環(huán)系統(tǒng)(如熱水供暖系統(tǒng)、空調(diào)冷凍水系統(tǒng))中，正確使用這種閥門，可以很方便地實現(xiàn)系統(tǒng)的流量分配;可以實現(xiàn)系統(tǒng)的動態(tài)平衡;可以大大簡化系統(tǒng)的調(diào)試工作;可以穩(wěn)定泵的工作狀態(tài)等。 Electric single-seat regulating valve is a new type control valve types themselves. Compared with the manual control valve, its advantage is able to automatically adjust; Relative to the electric control valve, its advantage is not need external motivation. Application practice proved that in a closed water circulation system, such as hot water heating system, air conditioning chilled water system), the proper use of the valve, the flow distribution can be easily implemented system; Can realize the dynamic equilibrium of system; Can greatly simplify the system debugging work; Fix the pump working condition, etc. 四、電動單座調(diào)節(jié)閥特點 1、可調(diào)節(jié)范圍大，固有可調(diào)比為50，流量特性有直線和等百分比。 2、閥體按流體力學(xué)原理設(shè)計的等截面低流阻流道，額定流量系數(shù)增大30%。 3、調(diào)節(jié)切斷型采用軟密封結(jié)構(gòu)閥芯，達(dá)VI級泄漏標(biāo)準(zhǔn)(零泄漏)。 4、伺服放大器采用深度動態(tài)負(fù)反饋，可提高自動調(diào)節(jié)精度。 5、電動操作器有多種形式，可適用于4~20mA。DC或0~10mA.DC。 6、波紋管密封型調(diào)節(jié)閥對移動的閥桿形成完全的密封，堵絕流體外漏。 7、電子型電動調(diào)節(jié)閥可直接由電流信號控制閥門開度，無需伺服放大器。 1, wide adjustable range, inherent adjustable ratio of 50, flow characteristic such as straight lines and percentage. 2, the valve body according to the fluid mechanics principle design of cross section, such as low flow resistance of fluid, rated flow coefficient increases by 30%. 3, adjust the cutting type USES the soft sealing structure of valve core, grade VI leakage standard (zero leakage). 4, the depth of the servo amplifier adopts dynamic negative feedback, can automatically adjust the accuracy. 5, electric operator has a variety of forms, can be applied to 4 ~ 20 ma. The DC or 0 ~ 10 ma. DC. 6, bellows seal type regulator for mobile stem form completely sealed, plugging fluid leakage. 7, electrical power regulator can be directly controlled by the current signal valve opening, without the servo amplifier.
