進(jìn)口氣動隔膜調(diào)節(jié)閥(德國OLES奧萊斯)

【進(jìn)口氣動隔膜調(diào)節(jié)閥】詳細(xì)說明：

氣動隔膜調(diào)節(jié)閥具有結(jié)構(gòu)簡單、流路阻小、流通力較同口徑的其它閥大，無泄漏，能用于高粘度及懸浮顆粒流體的調(diào)節(jié)，根據(jù)隔膜材料的不同（橡膠或聚四氟乙烯）適用于調(diào)節(jié)強(qiáng)堿、強(qiáng)腐蝕性介質(zhì)。由隔膜閥配用氣動薄膜執(zhí)行機(jī)構(gòu)組成。隔膜與閥體間“山”形凸出面進(jìn)行密封,與外界隔開(無填料函),適合于要求耐腐蝕、劇毒場合。氣動隔膜調(diào)節(jié)閥采用模塊化設(shè)計，可采用不同組合、配用多種附件。其主要特點(diǎn)如下：

(1) 采用輕型執(zhí)行機(jī)構(gòu)，高度及重量均可減小30%。

(2) 閥內(nèi)表面有多種材料涂復(fù)層，避開介質(zhì)直接接觸，承受強(qiáng)閥腐蝕性介質(zhì)的腐蝕。

(3) 閥門關(guān)閉時，內(nèi)、外泄漏量為零，適合于劇毒介質(zhì)或不允許污染介質(zhì)的閥節(jié)。

(4) 流路簡單，阻力小，額定流量系數(shù)比同口徑單座，套筒調(diào)節(jié)閥大。

Pneumatic diaphragm control valve has simple structure, small flow resistance, larger flow force than other valves of the same caliber, no leakage, and can be used for adjusting high viscosity and suspended particle fluid. According to the different diaphragm materials (rubber or PTFE), it is suitable for adjusting strong alkali and corrosive media. The utility model is composed of a diaphragm valve and a pneumatic film actuator. The hill-shaped protrusion between the diaphragm and the valve body is sealed and separated from the outside (without packing box), which is suitable for the occasions requiring corrosion resistance and severe toxicity. The pneumatic diaphragm control valve adopts modular design, which can adopt different combinations and various accessories. Its main characteristics are as follows:

(1) With light actuator, the height and weight can be reduced by 30%.

(2) The inner surface of the valve is coated with a variety of materials to avoid direct contact with the medium and to withstand the corrosion of the corrosive medium of the strong valve.

(3) When the valve closes, the internal and external leakage is zero, which is suitable for valve sections with highly toxic or non-polluting media.

(4) The flow path is simple, the resistance is small, the rated flow coefficient is bigger than that of single seat with the same caliber, and the sleeve regulating valve is bigger.

【進(jìn)口氣動隔膜調(diào)節(jié)閥】應(yīng)用原理：

調(diào)節(jié)閥由執(zhí)行機(jī)構(gòu)和閥體組成。內(nèi)含飼服功能，接受統(tǒng)一的4-20mA或1-5V．DC的標(biāo)準(zhǔn)信號，將電流信號轉(zhuǎn)變成相對應(yīng)的直線位移，自動地控制調(diào)節(jié)閥開度，達(dá)到對管道內(nèi)流體的壓力、流量、溫度、液位等工藝參數(shù)的連續(xù)調(diào)節(jié)。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。 

·調(diào)節(jié)閥又名流量控制閥，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，調(diào)節(jié)閥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。適用于空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品等介質(zhì)。

【進(jìn)口氣動隔膜調(diào)節(jié)閥】結(jié)構(gòu)特點(diǎn)：

1、結(jié)構(gòu)緊湊、啟閉迅速、流道暢通、流體阻力小。

2、密封性能好：利用四面閥座材料聚四氟乙烯彈性變形實(shí)現(xiàn)無泄漏密封。

3、一閥多用：任一通口可用作入口而無泄漏，三通既可制成L型通口，也可制成T型通口。

4、維修方便：在系統(tǒng)卸壓后，無需拆下整個閥體就可進(jìn)行檢查和維修。

5、泛適用于供水、石化、冶金、礦山、輕紡、能源、造紙、食品、鋼鐵等管路系統(tǒng)中對介質(zhì)流向進(jìn)行切換以及對介質(zhì)的分流或混合流體。 

通球閥介質(zhì)流向原理：

?三通球閥分L型和T型，介質(zhì)流通方向見下圖。

?L型三通球閥適用于介質(zhì)流向的切換，能使相互垂直的兩個通道連通：

?T型三通球閥適用于介質(zhì)的分流、合流或流向切換，T型孔道可以使三個通道互相連通或使其中兩個通道連通，三通球閥一般采用兩個閥座結(jié)構(gòu)，亦可根據(jù)用戶要求采用四閥座結(jié)構(gòu)。
