德國洛克供應優(yōu)質進口法蘭止回閥

一、進口法蘭止回閥描述：

德國LOCKE洛克進口法蘭止回閥止回閥是靠管路中介質本身的流動產(chǎn)生的力而自動開啟和關閉的，屬于一種自動閥門。止回閥用于管路系統(tǒng)，其主要作用是防止介質倒流、防止泵及其驅動電動機反轉，以及容器內介質的泄放。止回閥產(chǎn)品還可用于給其中的壓力可能升至超過主系統(tǒng)壓力的輔助系統(tǒng)提供補給的管路上。

The check valve of the imported flange check valve of Locke lock in Germany is opened and closed automatically by the force generated by the flow of the medium in the pipeline itself, which belongs to an automatic valve. The check valve is used in the pipeline system. Its main function is to prevent the backflow of medium, to prevent the pump and its driving motor from reversing, and to discharge the medium in the container. The check valve product can also be used in the pipeline to supply the auxiliary system whose pressure may rise above the main system pressure.

二、進口法蘭止回閥特點：

1.采用內裝搖臂旋啟式結構,所有啟閉件都裝于閥體內部,不穿透閥體

2.  搖臂和閥瓣連接處采用球面連接的結構,使得閥瓣在360°范圍內有一定的自由度,有適當?shù)奈⒘课恢醚a償

3. 閥門密封副的密封面堆焊合金鋼或硬質合金,即使用在有細粒的介質中亦不會因沖蝕而很快磨損

4. 用于較高壓力閥門的閥體與閥蓋的連接采用壓力自緊式密封結構,楔形密封環(huán)與四開環(huán)組合,壓力越高密封越可靠

1. The internal swing arm structure is adopted, and all the opening and closing parts are installed inside the valve body without penetrating the valve body

2. The connection between the rocker arm and the valve disc adopts the spherical connection structure, so that the valve disc has a certain degree of freedom within the 360 ° range, with appropriate micro position compensation

3. The sealing surface of the valve sealing pair is stacked with welding alloy steel or hard alloy, which will not wear out quickly due to erosion even if it is used in the medium with fine particles

4. The connection between the valve body and the valve cover for the valve with higher pressure adopts the pressure self tightening sealing structure. The wedge-shaped sealing ring is combined with the four open rings, and the higher the pressure, the more reliable the sealing is

三、進口法蘭止回閥應用范圍：  

法蘭式進口法蘭止回閥適用于壓力PN16~420工作溫度-45℃～570℃的石油、化工、制藥、化肥、電力行業(yè)等各種工況的管路上，旋啟止回閥適用介質為水、油品、蒸汽、酸性介質等。

The flange type imported flange check valve is suitable for the pipeline with pressure PN16 ~ 420, working temperature - 45 ℃ ~ 570 ℃ in petroleum, chemical industry, pharmaceutical industry, chemical fertilizer, electric power industry and other working conditions. The applicable medium of swing check valve is water, oil, steam, acid medium, etc.
