進口氣動隔膜調節閥(德國OLES奧萊斯)

【進口氣動隔膜調節閥】詳細說明：

氣動隔膜調節閥具有結構簡單、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節，根據隔膜材料的不同（橡膠或聚四氟乙烯）適用于調節強堿、強腐蝕性介質。由隔膜閥配用氣動薄膜執行機構組成。隔膜與閥體間“山”形凸出面進行密封,與外界隔開(無填料函),適合于要求耐腐蝕、劇毒場合。氣動隔膜調節閥采用模塊化設計，可采用不同組合、配用多種附件。其主要特點如下：

(1) 采用輕型執行機構，高度及重量均可減小30%。

(2) 閥內表面有多種材料涂復層，避開介質直接接觸，承受強閥腐蝕性介質的腐蝕。

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

(4) 流路簡單，阻力小，額定流量系數比同口徑單座，套筒調節閥大。

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.

【進口氣動隔膜調節閥】應用原理：

調節閥由執行機構和閥體組成。內含飼服功能，接受統一的4-20mA或1-5V．DC的標準信號，將電流信號轉變成相對應的直線位移，自動地控制調節閥開度，達到對管道內流體的壓力、流量、溫度、液位等工藝參數的連續調節。廣泛應用于電力、冶金、化工、石油、輕紡、制藥、造紙等工業部門的生產自動化控制。 

·調節閥又名流量控制閥，在工業自動化過程控制領域中，通過接受調節控制單元輸出的控制信號，調節閥借助動力操作去改變介質流量、壓力、溫度、液位等工藝參數的終控制元件。一般由執行機構和閥門組成。如果按行程特點，調節閥可分為直行程和角行程；按其所配執行機構使用的動力，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、泥漿、油品等介質。

【進口氣動隔膜調節閥】結構特點：

1、結構緊湊、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現無泄漏密封。

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：在系統卸壓后，無需拆下整個閥體就可進行檢查和維修。

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

通球閥介質流向原理：

?三通球閥分L型和T型，介質流通方向見下圖。

?L型三通球閥適用于介質流向的切換，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構，亦可根據用戶要求采用四閥座結構。
