进口夹套止回阀【进口止回阀***】德国奥莱斯
【进口夹套止回阀】详细说明:
夹套止回阀， 主要用于石油、化工、冶金、制药等各类系统中，以输送常温下会凝固的高粘度介质。保温系列阀门的夹套焊装于阀门的两法兰之间，阀门的侧面、底部设置有夹套的连接口。由于增加了夹套，保温阀门的连接法兰尺寸要比同一规格普通球阀的连接法兰大一到两个规格，但结构长度与同规格的阀门相同，夹套中可自由地流过蒸汽或其它热的保温介质，确保粘稠介质可顺畅地流过阀门。
Jacket check valves are mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems to transport high viscosity media that will solidify at room temperature. The jacket of the heat preservation series valves is welded between the two flanges of the valves. The side and bottom of the valves are provided with a jacket connection. Because of the addition of jacket, the size of connecting flange of thermal insulation valve is one to two specificati*** larger than that of common ball valve of the same specification, but the length of structure is the same as that of valve of the same specification. The jacket can flow freely through steam or other thermal insulation medium to ensure that the viscous medium can flow ***oothly through the valve.
【进口夹套止回阀】结构说明：
止回阀又称单向阀或逆止阀，其作用是防止管路中的介质倒流。水泵吸水关的底阀也属于止回阀类。
启闭件靠介质流动和力量自行开启或关闭，以防止介质倒流的阀门叫止回阀。止回阀属于自动阀类，主要用于介质单向流动的管道上，只允许介质向一个方向流动，以防止发生事故。
止回阀：按结构划分，可分为升降式止回阀、旋启式止回阀和蝶式止回阀三种。升降式止回阀可分为立式止回阀和卧式止回阀两种。旋启式止回阀分为单瓣式止回阀、双瓣式止回阀和多瓣式止回阀三种。蝶式止回阀为直通式止回阀、以上几种止回阀在连接形式上可分为螺纹连接止回阀、法兰连接止回阀和焊接止回阀三种。
Check valve is also called one-way valve or check valve. Its function is to prevent medium backflow in pipeline. The bottom valve of pump suction closure also belongs to check valve type.
The opening and closing parts open or close by themselves depending on the medium flow and force to prevent the medium backflow valve is called a check valve. Check valves belong to automatic valves. They are mainly used in pipelines where media flow in one direction. Only one direction is allowed to flow in order to prevent accidents.
Check valve: According to the structure, it can be divided into three types: lifting check valve, swing check valve and butterfly check valve. Lifting check valves can be divided into vertical check valves and horizontal check valves. Swing check valves are divided into three types: single-lobe check valves, double-lobe check valves and multi-lobe check valves. Butterfly check valves are straight-through check valves. The connection forms of the above check valves can be divided into threaded connection check valves, flanged connection check valves and welded check valves.
【进口夹套止回阀】原理说明：
1止回阀是一种自动阀门，靠介质本身流动产生的力而自动开、闭阀瓣，来防止介质倒流。
2、适用场所
需防止介质逆向流动的管段。
3、分类
止回阀：根据其结构可分为升降式止回阀、旋启式、蝶式、管道式、缓闭式和隔膜式止回阀等
