The rotation,detergence,and valve switching of the water-filter system are full-automatically controlled and, besides,the filter can well deal with the damage of generator set caused by sewage.

本文采用PLC实现新型滤水器，在旋转、排污、开关阀方面实现了全自动控制，并很好地解决了因水质污染对电厂发电机组带来的危害，克服了国内其它形式的滤水器无法解决的有机物过滤排污问题。

However, maintenance-free batteries, the maintenance of the existing system is without water, this way, will inevitably WATER POWER CONTROL VALVE cause the battery to water loss, the battery dry.

但在免维护电池中，旋塞阀在现有的维护制度下是不加水的，这样一来，将不可避免造成电池的失水、电池干枯。

Particularly in Slurry pumps the use of different process water system balancing valves, hydraulic conditions can be easy to achieve balance, designed to meet the requirements of environmental temperature and air-conditioning systems running at the end of the end device can not start and stop other interference.

特别是在异程水系统中使用平衡阀，可以容易实现水力工况平衡、满足设计环境温度的要求，并且在空调系统的运行中末端设备可以不受其他末端的启停干扰。

A water baffle is vertically arranged in the vessel, which divides the vessel into an intake region and an exhalant region; because the lower part of the water baffle and the lower part of the vessel are provided with a gap, the intake region is communicated with the exhalant region; an inlet and an outlet are respectively arranged on the upper part of the intake region and the upper part of the exhalant region; a drain is arranged at the lower part of the vessel, on which a drain valve is arranged.

一种茶浴炉炉外储垢排垢器为一密闭容器，容器内竖向装有阻水板，将容器分隔成进水区和出水区，阻水板与容器底部有一定间隙使进水区和出水区相通，进水区和出水区上部设有进水口和出水口，容器最低部设有排污口，其上装有排污阀。

Finally, another injector near the overflow valve injects air to expunge the water back into the recovery system.

最后，靠近溢出阀处的另一个喷嘴注入气体把水送回水再生循环系统。

The third problem is that the drainage system pump house, pressure relief valve discharge water should be discharged into the fire pool, or sewer and should not be ranked in a narrow ditch Ming.
