進口氣動薄膜調節(jié)閥(德國OLES奧萊斯)
【進口氣動薄膜調節(jié)閥】詳細說明:
動薄膜雙座調節(jié)閥采用雙導向結構，配用多彈簧執(zhí)行機構，具有結構緊湊、重量輕、動作靈敏、閥容量大、流量特性精確、拆裝方便等優(yōu)點。氣動薄膜雙座調節(jié)閥廣泛應用于控制氣體、液體、蒸汽等介質，工藝參數(shù)加如壓力、流量、溫度、液位保持在給定值。
氣動薄膜雙座調節(jié)閥特別適用于允許壓差較大，而允許泄漏量也較大的不是很清潔的介質場合。
氣動薄膜雙座調節(jié)閥系列產(chǎn)品有標準型、波紋管密封型、夾套保溫型等多種品種。產(chǎn)品公稱壓力等級有PN10、16、40、64；閥體口徑范圍DN20~200。適用流體溫度由-200℃~+560℃，其范圍內多種檔次。泄漏量標準有II 級或IV級。流量特性為線性或等百分比。多種多樣的品種規(guī)格可供選擇。
The movable film two-seat regulating valve adopts double guiding structure and multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics and convenient disassembly and assembly. Pneumatic film two-seat regulating valve is widely used to control gas, liquid, steam and other media. The process parameters such as pressure, flow rate, temperature and liquid level are kept at a given value.
The pneumatic film two-seat regulating valve is especially suitable for medium with large allowable pressure difference and large allowable leakage.
The series of pneumatic film two-seat regulating valves are standard type, bellows sealing type, jacket insulation type and other varieties. The nominal pressure grades of the products are PN10, 16, 40, 64, and the caliber range of the valve body is DN20-200. The applicable fluid temperature ranges from - 200 C to + 560 C, and there are many grades in the range. Leakage standards are level II or IV. Flow characteristics are linear or equal percentage. Various varieties and specifications are available.
【進口氣動薄膜調節(jié)閥】特點：
·氣動薄膜雙座調節(jié)閥，工作時穩(wěn)定性好。
·有兩個閥芯和閥座，采用“四通”閥體，可以方便地由正裝改裝成反裝，氣關閥變氣開閥。
·閥體按流體動力學原理設計的等截面低流阻流道，額定流量系數(shù)大。
·不平衡力小，允許使用壓差較大。
·執(zhí)行機構采用多彈簧結構，高度減小30%。重量減輕30%。
·可調范圍大，固有可調比為50%。
·波紋管密封型調節(jié)閥對移動的閥桿形成了*密封，堵絕流體外漏。
·調節(jié)閥帶有保溫夾套，用于流體冷卻后易結晶、凝固造成堵塞的場合。
