進口外螺紋焊接止回閥

一、進口外螺紋焊接止回閥

    品牌：美國威盾VTON

進口外螺紋焊接止回閥是指采用鍛造不銹鋼結(jié)構(gòu)，外螺紋的連接方式，帶焊接管，可拆卸，安裝維修方便。主要用于高壓加壓的天然氣加氣系統(tǒng)，防止加壓天然氣倒流的閥門。焊接式高壓單向閥是靠管路中介質(zhì)本身的流動產(chǎn)生的力而自動開啟和關閉的，屬于一種自動閥門。焊接式高壓單向閥只允許介質(zhì)向一個方向流動，而且阻止方向流動。

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.
