进口法兰止回阀德国洛克厂家强烈推荐

 

进口法兰止回阀特点：

1.采用内装摇臂旋启式结构,所有启闭件都装于阀体内部,不穿透阀体

2.  摇臂和阀瓣连接处采用球面连接的结构,使得阀瓣在360°范围内有一定的自由度,有适当的微量位置补偿

3. 阀门密封副的密封面堆焊合金钢或硬质合金,即使用在有细粒的介质中亦不会因冲蚀而很快磨损

4. 用于较高压力阀门的阀体与阀盖的连接采用压力自紧式密封结构,楔形密封环与四开环组合,压力越高密封越可靠

 

进口法兰止回阀应用范围：  

法兰式进口法兰止回阀适用于压力PN16~420工作温度-45℃～570℃的石油、化工、制药、化肥、电力行业等各种工况的管路上，旋启止回阀适用介质为水、油品、蒸汽、酸性介质等。

 

进口法兰止回阀描述：

德国《DE LOCKE》洛克进口法兰止回阀止回阀是靠管路中介质本身的流动产生的力而自动开启和关闭的，属于一种自动阀门。止回阀用于管路系统，其主要作用是防止介质倒流、防止泵及其驱动电动机反转，以及容器内介质的泄放。止回阀产品还可用于给其中的压力可能升至超过主系统压力的辅助系统提供补给的管路上。

Description of inlet flange check valve:
German "de Locke" imported flange check valve check valve is a kind of automatic valve, which is opened and closed automatically by the force generated by the flow of pipeline medium itself. Check valve is used in pipeline system, its main function is to prevent medium backflow, pump and its drive motor reverse, as well as the discharge of medium in the container. Check valve products can also be used to supply the auxiliary system whose pressure may rise above the main system pressure.
