进口衬氟隔膜阀工作稳定可靠-德国洛克品牌

进口衬氟隔膜阀结构特点:

1.复合隔膜阀将阀体下部内腔与阀盖内腔隔开，并与之形成直流通道，使隔膜上部的阀杆、阀瓣等内件与介质完全隔离，省去填料密封结构，介质的内漏和外漏可同时避免；

2.利用FEP(Teflon)氟塑料与全成橡胶复合而成的隔膜的带有Teflon氟塑料衬里层的阀门，可适于除“熔融碱金属、元素氟”外的各种强腐蚀性介质。

3.做为执行元件的膜片,由于频繁的启闭,易产生疲劳断裂,应视工况、介质的特性，进行定期更换。

4.氟塑料的防腐性能及推荐使用温度风“阀门及管路附件用氟塑料衬里性能表”。

5.衬氟隔膜阀与其它阀门的区别在于：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、 孺”等弊端。

6.由於隔膜阀的流道平滑、流阻小、故而可获得较大的流量。

7.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。

8.由於密封件为高有弹性的四氟隔膜，因此还具有较好的密封性和最小的关闭力。

9.本阀由阀体、阀盖、阀瓣、阀杆、隔膜和其它驱动零件等组成。

10.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，阀僻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。

Structure features of imported fluorine lined diaphragm valve:
1. The composite diaphragm valve separates the inner cavity of the lower part of the valve body from the inner cavity of the valve cover, and forms a DC channel with it, so that the inner parts of the upper part of the diaphragm, such as the valve stem and disc, are completely isolated from the medium, and the packing sealing structure is omitted, so that the internal and external leakage of the medium can be avoided at the same time;
2. The valve with Teflon fluoroplastic lining layer made of FEP (Teflon) fluoroplastic and all rubber composite diaphragm can be suitable for all kinds of strong corrosive media except "molten alkali metal, element fluorine".
3. As the actuator, the diaphragm is prone to fatigue fracture due to frequent opening and closing, so it should be replaced regularly according to the working condition and medium characteristics.
4. Anticorrosion performance and recommended temperature of fluoroplastics "performance table of fluoroplastics lining for valves and pipeline accessories".
5. The difference between the fluorine lined diaphragm valve and other valves is that the structure without stuffing box is adopted; the diaphragm of fluorine lined diaphragm valve can completely isolate the corrosive medium in the flow channel from all driving parts, thus eliminating the disadvantages of "running, emitting, dripping and shrinking" of common valves.
6. Due to the smooth flow passage and small flow resistance of diaphragm valve, a larger flow rate can be obtained.
7. The inner cavity of fluorine lined diaphragm valve body is lined with perfluorinated F46. Therefore, it has superior corrosion resistance.
8. As the seal is a highly elastic tetrafluoro diaphragm, it also has better sealing performance and minimum closing force.
9. The valve consists of valve body, valve cover, valve disc, valve stem, diaphragm and other driving parts.
10. The opening and closing of the valve is achieved by rotating the hand wheel. The upper end of the valve cover is marked with the display color that can see the opening or closing position of the valve to indicate the opening and closing stroke of the valve. When the hand wheel is placed clockwise, the hand wheel will move down and the valve will drive the diaphragm down to cut off the passage; otherwise, the valve will open and the color will be revealed.

进口衬氟隔膜阀产品简介：

德国洛克 《DE LOCKE 》进口衬氟隔膜阀是一种特殊形式的具有截断功能的阀，其启闭件由钢质阀瓣与软质材料（橡胶和氟塑料复合）制成的隔膜组成，并将阀体内腔与阀盖内腔隔开以达到截断管内介质目的。

Introduction of imported fluorine lined diaphragm valve products:
The fluorine lined diaphragm valve imported from German Locke "de Locke" is a special type of valve with cut-off function. Its opening and closing parts are composed of steel disc and diaphragm made of soft material (rubber and fluoroplastic), and separate the inner cavity of the valve body from the inner cavity of the valve cover, so as to cut off the medium in the pipe.
