直流式隔膜阀的概述:
直流式隔膜阀专用于控制非腐蚀性或一般腐蚀性介质,阀体内腔表面无衬里或覆有可供选择的各种橡胶,适用于不同工作温度和 流体管路。适用温度:≤85℃、≤100℃、≤120℃(按照衬里和隔膜材料)。压力等级:PN0.6、1.0、1.6。
直流式隔膜阀的结构特点:
隔膜阀是一种特殊形式的截止阀;
1、弹性密封的开闭件,确保没有内漏;
2、流线型的流道,使得压力损失小;
3、没有填料函,因此没有外漏;
4、阀体与盖被中间隔膜隔开,使得隔膜上方的阀盖,阀杆零件不受介质侵蚀;
5、隔膜可更换,维护费用低;
6、衬里材料的多样性,可适用于各种介质,并具有良好的耐腐蚀性。

Overview of DC diaphragm valve:
DC type diaphragm valve is designed to control non corrosive or corrosive media, the body cavity surface unlined or covered with all kinds of rubber alternative, suitable for different temperature and fluid pipeline. Application: temperature ≤ 85 ℃, ≤ 100 ℃, ≤ 120 ℃ (in accordance with the lining and diaphragm material). Pressure rating: PN0.6, 1, 1.6.
The structure characteristics of the DC diaphragm valve:
The diaphragm valve is a special form of cut-off valve;
Closure of 1, elastic sealing, to ensure no leakage;
Channel 2, streamlined, so that the pressure loss;
3, no stuffing, so no external leakage;
4, the valve body and the cover is separated from the intermediate diaphragm, the diaphragm at the top of the valve cover, valve parts can not be corroded by the medium;
5, the diaphragm can be replaced, the maintenance cost is low;
6, the lining material diversity, suitable for a variety of media, and has good corrosion resistance.直流式隔膜阀概述 和结构特点。
