一、进口内螺纹隔膜阀产品介绍

进口内螺纹隔膜阀，Internal thread diaphragm valve，也叫丝扣隔膜阀，内丝隔膜阀，内螺纹不锈钢隔膜阀，是指采用内螺纹的连接方式，一般是小口径隔膜阀，启闭件是一块用软质材料制成的隔膜，把内腔与阀盖内腔及驱动部件隔开的隔膜阀，专用于控制一般腐蚀性介质，可供各类管路或设备上作启闭及节流用。
内螺纹隔膜阀采用橡胶或塑料等软质密封制作的隔膜，密封性较好。由于隔膜为易损件，应视介质特性而定期更换。内螺纹隔膜阀用于含硬质悬浮物的介质；由于内螺纹隔膜阀介质只与阀体和隔膜接触，所以无需填料函，不存在填料函泄漏问题，对阀杆部分无腐蚀可能。

Internal thread diaphragm valve, Internal thread diaphragm valve， Also known as threaded diaphragm valve, internal thread diaphragm valve, or internal thread stainless steel diaphragm valve, it refers to a small diameter diaphragm valve that uses internal thread connection. The opening and closing parts are a diaphragm made of soft materials, which separates the inner chamber from the valve cover inner chamber and driving components. It is specifically used to control general corrosive media and can be used for opening, closing, and throttling on various pipelines or equipment.

The internal threaded diaphragm valve uses a diaphragm made of soft sealing materials such as rubber or plastic, which has good sealing performance. Due to the fact that the diaphragm is a vulnerable component, it should be replaced regularly depending on the characteristics of the medium. Internal threaded diaphragm valves are used for media containing hard suspended solids; Due to the fact that the medium of the internally threaded diaphragm valve only comes into contact with the valve body and diaphragm, there is no need for a packing box, and there is no leakage problem with the packing box, which may cause corrosion to the valve stem.
