产品介绍
一、进口外螺纹焊接止回阀
进口外螺纹焊接止回阀是指采用锻造不锈钢结构,外螺纹的连接方式,带焊接管,可拆卸,安装维修方便。主要用于高压加压的天然气加气系统,防止加压天然气倒流的阀门。焊接式高压单向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。焊接式高压单向阀只允许介质向一个方向流动,而且阻止方向流动。
Detachable welding high-pressure check valve is mainly used for pressurized gas filling system, pressurized gas to prevent backflow valve. Welding type high pressure check valve is generated by the pipeline flow of the medium itself force automatically turned on and off, is an automatic valve. Welding type high pressure check valve is only allowing media to flow in one direction, and stop the flow direction.
