进口法兰止回阀详细说明,特点/原理,报价
【进口法兰止回阀】详细说明：
法兰式止回阀是指依靠介质本身流动而自动开、闭阀瓣，用来防止介质倒流的阀门，又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门，其主要作用是防止介质倒流、防止泵及驱动电动机反转，以及容器介质的泄放。止回阀还可用于给其中的压力可能升至超过系统压的辅助系统提供补给的管路上。止回阀主要可分为旋启式止回阀(依***旋转)与升降式止回阀(沿轴线移动)。
这种类型的阀门的作用是只允许介质向一个方向流动，而且阻止方向流动。通常这种阀门是自动工作的，在一个方向流动的流体压力作用下，阀瓣打开;流体反方向流动时，由流体压力和阀瓣的自重合阀瓣作用于阀座，从而切断流动。
其中法兰式止回阀就属于这种类型的阀门，它包括旋启式止回阀和升降式止回阀。旋启式止回阀有一介铰链机构，还有一个像门一样的阀瓣自由地靠在倾斜的阀座表面上。为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、***的与阀座接触。阀瓣可以全部用金属制成，也可以在金属上镶嵌皮革、橡胶、或者采用合成覆盖面，这取决于使用性能的要求。旋启式止回阀在完全打开的状况下，流体压力几乎不受阻碍，因此通过阀门的压力降相对较小。
Flanged check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, also known as check valve, one-way valve, counterflow valve, and back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. Check valves can also be used in pipelines to supply auxiliary systems where pressure may rise above system pressure. Check valves can be divided into swing check valves (rotating according to the center of gr***ity) and lift check valves (moving along the axis).
The function of this type of valve is to allow the medium to flow in only one direction and to prevent the flow in the direction. Usually, the valve operates automatically, and the disc opens under the action of a fluid pressure flowing in one direction. When the fluid flows in the opposite direction, the disc acts on the seat by the fluid pressure and the self-coincidence disc of the disc, thus cutting off the flow.
Flanged check valve belongs to this type of valve, which includes swing check valve and lift check valve. Swing check valves h***e a hinged mechani*** and a door-like disc that freely rests on the inclined seat surface. In order to ensure that the disc can reach the proper position of the seat surface every time, the disc is designed in a hinge mechani*** so that the disc has sufficient swing space and makes the disc truly and comprehensively contact with the seat. Valve discs can be made entirely of metal, or can be metal inlaid with leather, rubber, or synthetic coverage, depending on the performance requirements. When swing check valve is fully opened, the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively ***all.
产品特点：
1.全通径流线形设计，水头损失小,不易堆积杂物。阀体整体环氧树脂涂装，使阀门的壳体完全与介质隔离，有效防止阀门被介质腐蚀。
2.橡胶瓣由钢板、钢棒及强化尼龙布衬底，外层披覆橡胶制成,弹性好,使用寿命长。3结构简单。 握作可靠。 维护简便。
原理作用说明：
止回阀的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。止回阀一般分为升降式、旋启式、蝶式及卧式等四种类型，通式升降式止回阀应安装于水平管路上，立式升降式止回阀和底阀一般安装在垂直管路上，并且介质自下而***动，旋启式止回阀安装位置不受限制，通常安装于水平管路，但也可以安装于垂直管路或倾料管路上。注意：止回阀只允许介质向一个方向流动，应特别注意介质流动方向，应使介质正常流动方向与阀体上指示的箭头方向相一致，否则就会截断介质的正常流动。
法兰止回阀是指依靠介质本身流动而自动开、闭阀瓣，用来防止介质倒流的阀门，又称逆止阀、单向阀、逆流阀、和背压阀。止回阀属于一种自动阀门，其主要作用是防止介质倒流、防止泵及驱动电动机反转，以及容器介质的泄放。
