進口旋啟式止回閥優(yōu)選德國洛克

進口旋啟式止回閥結構優(yōu)點：

1、旋啟式止回閥的采用內(nèi)裝搖臂旋啟式結構，閥門的所有啟閉件都裝于閥體內(nèi)部，不穿透閥體，除了中法蘭部位用密封墊片和密封環(huán)外，整體沒有外漏點，杜絕閥門外泄的可能。

2、旋啟式止回閥搖臂和閥瓣連接處采用球面連接的結構，使得閥瓣在360度范圍內(nèi)有一定的自由度，有適當?shù)奈⒘课恢醚a償。

3、密封副配對先進合理，閥瓣、閥座密封面采用鐵基合金或司太立（Stellite）鈷基硬質(zhì)合金堆焊面成，耐磨、耐高溫、耐腐蝕、抗擦傷性能好，使用壽命長。

4、適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)。

進口旋啟式止回閥描述：

德國《DE LOCKE》洛克進口旋啟式止回閥又稱單向閥或逆止閥，其作用是防止管路中的介質(zhì)倒流。啟閉件靠介質(zhì)流動和力量自行開啟或關閉，以防止介質(zhì)倒流的閥門叫止回閥。止回閥屬于自動閥類，主要用于介質(zhì)單向流動的管道上，只允許介質(zhì)向一個方向流動，以防止發(fā)生事故。本類閥門在管道中一般應當水平安裝。

Description of inlet swing check valve:
German "de Locke" imported swing check valve, also known as one-way valve or check valve, its function is to prevent the medium in the pipeline from backflow. Open and close by the medium flow and force to open or close, in order to prevent the medium backflow of the valve called check valve. Check valve is an automatic valve, which is mainly used in the pipeline with one-way flow of medium. It only allows the medium to flow in one direction to prevent accidents. This kind of valve should be installed horizontally in the pipeline.
