产品介绍

一、进口衬氟止回阀概述

进口衬氟止回阀Fluorine lining check valve，是指阀体内腔表面覆有聚四氟乙烯，具有强度高、耐腐蚀性能好的特点，专用于控制强腐蚀性和强酸碱性介质，防止介质倒流的阀门；

美国威盾VTON衬氟止回阀阀瓣都是围绕阀座外的（销）轴、镶嵌在阀体与阀盖之间形成的特殊凹槽内、启闭灵活，密封可靠。除了阀体，阀瓣外，复位弹簧也全部包衬了耐强腐蚀的四氟，设计合理的弹簧，使阀瓣在低压区内也能产生足够的密封比压，保证阀门在低压力区密封的可靠性。主要产品有：衬氟止回阀，衬里止回阀，全衬止回阀，衬氟逆止阀，衬氟单向阀，衬氟法兰止回阀，衬氟升降式止回阀，衬氟旋启式止回阀。

Fluorine lining check valve refers to a valve whose inner surface of the valve body is covered with polytetrafluoroethylene, which has the characteristics of high strength and good corrosion resistance. It is specifically used to control strong corrosive and strong acid-base media and prevent media backflow;

The VTON fluorine lined check valve disc is surrounded by a (pin) axis outside the valve seat, embedded in a special groove formed between the valve body and the valve cover, with flexible opening and closing, and reliable sealing. In addition to the valve body and disc, all the reset springs are also lined with strong corrosion-resistant PTFE. A well-designed spring ensures that the disc can generate sufficient sealing pressure in the low-pressure area, ensuring the reliability of the valve's sealing in the low-pressure area. The main products include: fluorine lined check valves, lining check valves, full lining check valves, fluorine lined check valves, fluorine lined one-way valves, fluorine lined flange check valves, fluorine lined lift check valves, and fluorine lined swing check valves.
