進(jìn)口電動(dòng)隔膜調(diào)節(jié)閥,(德國(guó)OLES奧萊斯)
【進(jìn)口電動(dòng)隔膜調(diào)節(jié)閥】詳細(xì)說明：
電動(dòng)隔膜調(diào)節(jié)閥由直行程電動(dòng)執(zhí)行機(jī)構(gòu)和隔膜閥組成。電動(dòng)執(zhí)行機(jī)構(gòu)為電子式一體化結(jié)構(gòu)，內(nèi)有伺服放大器,輸入控制信號(hào)（4-20mADC或1-5VDC）及電源即可控制閥門開度,達(dá)到對(duì)壓力、流量、液位、溫度等工參數(shù)的調(diào)節(jié)。具有動(dòng)作靈敏、連線簡(jiǎn)單、流量大、體積小、調(diào)節(jié)精度高等特點(diǎn)。控制精度和性能比有明顯提高。隔膜閥體流通平滑、節(jié)流元件為彈性隔膜閥，閥蓋上無填料函。因而閥流通能力比一般調(diào)節(jié)閥大且無泄漏，在許用壓差范圍內(nèi)可作切斷閥用。該閥適用于高粘性流體、懸浮狀顆粒、纖維介質(zhì)和有毒介質(zhì)、腐蝕性介質(zhì)的調(diào)節(jié)場(chǎng)合。
The electric diaphragm regulating valve is composed of a direct stroke electric actuator and a diaphragm valve. The electric actuator is an electronic integrated structure with servo amplifier. The valve opening can be controlled by input of control signal (4-20mADC or 1-5VDC) and power supply, so as to adjust the working parameters such as pressure, flow, liquid level and temperature. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment precision. The control accuracy and performance are obviously improved. The flow of diaphragm valve body is smooth, the throttling element is elastic diaphragm valve, and there is no filling box on the valve cover. Therefore, the flow capacity of the valve is larger than that of the general control valve and there is no leakage. It can be used as a shutoff valve in the allowable pressure difference range. The valve is suitable for regulating high viscous fluids, suspended particles, fiber media, toxic media and corrosive media.
【進(jìn)口電動(dòng)隔膜調(diào)節(jié)閥】特點(diǎn)：
采用輕型執(zhí)行機(jī)構(gòu)，高度及重量均可減小30%。閥體內(nèi)表面有多種材料涂復(fù)層，避免介質(zhì)直接接觸，承受強(qiáng)閥腐蝕性介質(zhì)的腐蝕。閥門關(guān)閉時(shí)，內(nèi)、外泄漏量為零，特別適合于劇毒介質(zhì)或不允許污染介質(zhì)的閥節(jié)。流路簡(jiǎn)單，阻力小，額定流量系數(shù)比同口徑單座，套筒調(diào)節(jié)閥大。零配件材料：閥體：HT200、ZG230～450或下述材質(zhì)襯里隔膜：丁荃膠、天然膠、聚四氟乙烯波紋。薄膜：ding腈橡膠夾增強(qiáng)滌綸織物
