進(jìn)口立式止回閥使用壽命-德國洛克 

進(jìn)口立式止回閥結(jié)構(gòu)特點：

1、閥瓣行程短，靈敏性高，大大減少了閥瓣關(guān)閉所需時間，有效降低了止回閥的水錘壓力。

2、密封面采用合金鋼或硬質(zhì)合金，密封副材料配對合理，使用壽命長。

進(jìn)口立式止回閥工作原理：

止回閥開啟是指依靠介質(zhì)正向流動打開閥瓣，同樣的道理介質(zhì)倒流推動閥瓣而關(guān)閉，止回閥還稱之為逆止閥、單向閥、逆流閥、和背壓閥等。多屬于自動閥門，主要功能是用來防止介質(zhì)倒流，防止泵及驅(qū)動電動機(jī)反轉(zhuǎn)和容器介質(zhì)的泄放使用。同時還用于壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)中作為安全保護(hù)。

進(jìn)口立式止回閥描述：

德國《DE LOCKE》洛克進(jìn)口立式止回閥，采用立式結(jié)構(gòu)，加彈簧止回，通常用于豎立安裝的止回閥。正常處于關(guān)閉狀態(tài)，由于管線中進(jìn)口端介質(zhì)的壓力作用，而克服彈簧阻力使閥門開啟。當(dāng)進(jìn)口端介質(zhì)壓力低于出口端時，彈簧將閥芯推向閥座而使閥門關(guān)閉，阻止介質(zhì)逆流，故起止回作用。 本閥門由于采用彈簧支撐閥芯，故采用立式安裝或臥式裝均可。廣泛使用于化工、液化石油氣、流體等行業(yè)。

Description of imported vertical check valve:
German "de Locke" imported vertical check valve, vertical structure, plus spring check, usually used for vertical installation of check valve. The valve is normally closed. Due to the pressure of the medium at the inlet end of the pipeline, it overcomes the spring resistance and makes the valve open. When the medium pressure at the inlet end is lower than that at the outlet end, the spring pushes the valve core to the valve seat to close the valve and prevent the medium from countercurrent, so it plays a check role. The valve adopts spring to support the valve core, so it can be installed vertically or horizontally. Widely used in chemical, liquefied petroleum gas, fluid and other industries.
