一、进口直通隔膜阀产品概述

进口直通式隔膜阀, Straight through diaphragm valve，也叫直通式隔膜阀，是指结构形式与闸阀相似，直通的阀体通道，利用膜片的上升和下压来实现阀门的开启和关闭，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液体管路的隔膜阀。

Straight through diaphragm valve， Also known as a through diaphragm valve, it refers to a valve body channel with a structure similar to a gate valve, which uses the upward and downward pressure of the diaphragm to achieve the opening and closing of the valve. It is specifically designed to control non corrosive or generally corrosive media. The surface of the valve body cavity is unlined or covered with various rubber options, and is suitable for different working temperatures and liquid pipelines.

二、进口直通隔膜阀产品特点

1. 直通隔膜阀弹性密封的开闭件，确保没有内漏；

2. 直通隔膜阀流线型的流道，使得压力损失小；

3. 直通隔膜阀没有填料函，因此没有外漏；

4. 直通隔膜阀阀体与盖被中间隔膜隔开，使得隔膜上方的阀盖，阀杆等零件不受介质侵蚀;

5. 直通隔膜阀隔膜可更换，维护费用低；

6. 直通隔膜阀衬里材料的多样性，可适用于各种介质，并具有强度高、耐腐蚀性能好的特点。

1. The opening and closing parts of the diaphragm valve with elastic seal ensure no internal leakage;

2. The streamlined flow passage of the diaphragm valve reduces pressure loss;

3. The through diaphragm valve does not have a packing box, so there is no leakage;

4. The valve body and cover of the diaphragm valve are separated by a middle diaphragm, so that the valve cover and valve stem above the diaphragm are not corroded by the medium;

5. The diaphragm of the through diaphragm valve can be replaced, and the maintenance cost is low;

6. The diversity of lining materials for through diaphragm valves can be applied to various media and has the characteristics of high strength and good corrosion resistance.
