The check valve is used in the sewage lifter, which can solve the problem caused by sewage backflow. The drain pipe with a check valve can prevent the backflow of sewage from damaging the equipment and reduce the water storage capacity in the equipment. The working purpose of the sewage lifter is to pump away the water that cannot be drained by gravity flow through the strong pressure generated by the pump, and it is mostly used in basement buildings. The basement sewage is pumped to the upper floor or the nearby sewage pipe through the sewage pipe and flows away. However, after the sewage lifter stops operating, some of the sewage still in the sewage pipe starts to flow back without pressure. As the sewage pipe is generally vertically upward, the pressure generated by the backflow is huge.

With China's economic development entering the new normal, the development environment of the steel industry has undergone profound changes. In 2015, China's steel consumption and production both entered the peak arc top area and showed a downward trend, the main steel industry from the small profit operation into the overall loss, the industry development into the "severe winter" period. At the same time, the central government's proposal to promote supply-side structural reforms and the State Council's fiscal, taxation and financial policies to resolve excess steel production capacity also provide a historical opportunity for the steel industry to completely get rid of the predicament. 1. 2015 steel industry operation (I) production and consumption double decline. In 2015, the national crude steel output was 0.804 billion tons, the same

Common Problems and Maintenance of High Pressure Water Descaling Valve

The key component of the high-pressure water descaling valve device is the descaling nozzle. The state of the descaling nozzle directly affects the surface quality of the product. Therefore, it is of great significance to do a good job in the maintenance of the high-pressure water descaling nozzle. The abnormal condition of the descaling nozzle is mainly manifested in three aspects: 1. The nozzle core of the descaling valve nozzle is fatigue and worn, and slight cracks appear at both ends of the long axis. When the high-pressure water flow passes through the crack part of the nozzle core, turbulence will be formed, the outflow direction will be confused, the energy of the high-pressure water will be consumed, the impact force will be reduced, and the descaling effect will be affected. The phenomenon is that the high-pressure water flow emitted by the nozzle core diverges and is white in the case of strong light, which is more transparent than other nozzle cores.
