An overview:
Fluorine lined diaphragm valve is a special form of a truncated function valve, used in chemical, acid, alkali, smelting, rare earth, pesticide industry production system is widely.
Design features of two:
1 different fluorine lining diaphragm valve and other valves in: the structure without stuffing; fluorine lined diaphragm valves can make the corrosive medium flow channel and all drive components in total isolation, so as to prevent the valve is usually "run, run, drip, leak" of abuse.
2 the smooth channel of diaphragm valve, the flow resistance is small, so it can obtain larger flow.
3 fluorine lined diaphragm valve body cavity full fluorine lining F46. It has the characteristics of superior corrosion resistance.
4 the seal for the PTFE diaphragm elastic. It can seal and minimum closing force better.
5 the valve from the valve body, valve cover, valve, valve, diaphragm and other driving parts.
6 the opening and closing of the valve is to rely on the rotating wheel at. The valve in the valve cover is marked with a glimpse of the valve open or closed position of the display color stop, to open and close the valve stroke indicator. When the hand wheel clockwise position, the handwheel is down, the valve diaphragm down the pathway of spurring truncation; otherwise the valve is open, color don't came.
7 the valve uses a standard: according to GB12239 regulations, and in accordance with BS5156
By the way three:
Fluorine lined diaphragm valve is widely used in chemical, acid, alkali, smelting, rare earth, pesticide, dye, medicine, papermaking, electroplating, electrolysis, pickling, radio, foil, scientific research institutions, national defense industry and other industries in different condition of strong corrosive medium, and can replace the expensive rare metal valve. 衬氟隔膜阀概述及特点。

一.概述:
衬氟隔膜阀是一种特殊形式的具有截断功能的阀门,在化工、制酸、制碱、冶炼、稀土、农药等行业生产系统中应用较为广泛。
二.设计特点:
1.衬氟隔膜阀与其它阀门最大的区别在於:采用无填料函的构造;衬氟隔膜阀隔膜可使流道内的腐蚀性介质与所有驱动部件处於完全隔离的状态,从而杜绝了通常阀门的“跑、冒、滴、漏”等弊端。
2.由於隔膜阀的流道平滑,流阻小,故而可获得较大的流量。
3.衬氟隔膜阀的阀体内腔为全氟F46内衬。因此具有优越的耐腐蚀的特点。
4.由於密封件为富有弹性的四氟隔膜。因此还具有较好的密封性和最小的关闭力。
5.本阀由阀体、阀盖、阀瓣、阀杆、隔膜和其它驱动零件等组成。
6.阀门的启闭是依靠旋转手轮而达到的。本阀在阀盖上端标有可窥见阀门处启或闭位置的显示色别,以指示阀门的启闭行程。当顺时针放置手轮时,手轮即下移,阀瓣随之带动隔膜下降使通路截断;反之则阀门即开启,色别随之显露。
7.本阀采用标准:按照GB12239的规定,并符合BS5156的
三.用 途:
衬氟隔膜阀广泛适用于化工、制酸、制碱、冶炼、稀土、农药、染料、医药、造纸、电镀、电解、酸洗、无线电、化成箔、科研机构、国防工业等行业不同工况下的强腐蚀性介质,而且可以代替价格昂贵的稀有金属阀门。隔膜阀的维护保养和安装使用。
