进口球型止回阀(德国OLES奥莱斯阀门)
【进口球型止回阀】详细说明：
多球形止回阀，采用橡胶bao皮滚球为阀瓣，在介质的作用下，可在阀体内的整体式滑道上作上下左右滚动，从而打开或关闭阀门。消声式关闭，不产生水锤，密封性能好。阀体采用全水流通道，流量大，阻力小，水头损失比旋启式小50%。水平或垂直安装均可，可用于冷水、热水、工业及生活用水管网系统中，更适应用潜水排水污泵，介质温度为0～80℃
Multi-spherical check valve, using rubber wrapped ball as valve disc, under the action of medium, can roll up and down on the integral slideway of the valve body, thus opening or closing the valve. The silencing type closes, does not produce water hammer, and has good sealing performance. The valve body adopts full flow passage with large flow rate, small resistance and 50% less head loss than the swing type. It can be installed horizontally or vertically. It can be used in cold water, hot water, industrial and domestic water pipeline system. It is more suitable for submersible sewage pump. The medium temperature is 0-80 C
【进口球型止回阀】结构特点：
1、结构长度短，其结构长度只有传统法兰止回阀的1/4~1/8
2、体积小、重量轻、其重量只有传统微阻缓闭止回阀的1/4~1/20
3、阀瓣关闭快速，水锤压力小
4、水平或垂直管道均可使用，安装方便
5、流道通畅、流体阻力小
6、动作灵敏、密封性能好
7、阀瓣行程短、关阀冲击力小
8、整体结构、简单紧凑、造型美观
9、使用寿命长、可靠性高。
1. Structural length is short, and its structural length is only 1/4~1/8 of the traditional flange check valve.
2. Small size, light weight, its weight is only 1/4~1/20 of the traditional micro-blocking check valve.
3. The valve disc closes quickly and the water hammer pressure is low.
4. Horizontal or vertical pipes are available and easy to install.
5. Flow passage is unobstructed and fluid resistance is small.
6. Sensitive movement and good sealing performance
7. Short disc stroke and low impact of valve closure
8. Integral structure, simple and compact, beautiful appearance
9. Long service life and high reliability.
【进口球型止回阀】特性：
滑道滚球式止回阀，采用橡胶bao皮滚动球为阀瓣，在介质的作用下，可在阀体的整体式滑道上作上下滚动，从而打开或关闭阀门，密封性能好，消声市关闭，不产生水锤。
阀体采用全水流通道，流量大，阻力小，水损失比旋启式小50%，在水平或垂直安装均可，可用于冷水、热水、工业及生活污水管网，更适合潜水排污泵，介质温度0-80℃。可安装于水泵出水口处，以防止倒流及水锤对泵损害。
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，并且介质自下而上流动，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*，否则就会截断介质的正常流动。
