Eccentric hemispherical valve in the appearance characteristics

Eccentric hemispherical valve is divided into two kinds in appearance structure 1. Top-mounted type: mainly for the medium with very serious corrosion and wear, the replacement and maintenance of the top-mounted structure in the damaged opening and closing parts is very convenient, without removing the whole valve from the pipeline, which greatly saves maintenance time and cost. 2. Side-mounted type: side-mounted type has compact structure and light valve quality, which is suitable for occasions requiring valve installation space. Features of eccentric half ball valve

Process Improvement of Wear-resistant Ball Valve

The wear-resistant cast stone ball valve bonnet produced by Sanjing valve is made of ZG230-450 materials. During the strength test during production processing and after assembly, it is found that there are different degrees of shrinkage porosity and shrinkage cavity around the bonnet located in Figure 1A (taking DN300 ball valve bonnet as an example). The casting blank cannot be seen by naked eyes, while water seepage occurs after mechanical processing or strength test. Repair welding is not a good way, at the same time, the strength cannot be guaranteed, and the economic loss is great.

Fixed electric ash unloading ball valve

1. fixed electric ash unloading ball valve product introduction: Electric fixed unloading ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Special considerations have been made in the design of its safety and resistance to harsh environments, and it is suitable for various corrosive media. Compared with the rolling ball valve, the acting force generated by the fluid pressure in front of the valve in the pipeline on the ball is all transmitted to the bearing during operation. The ball will not move. The valve seal is realized by pushing the valve seat by the spring and the medium pressure, so the valve seat will not bear excessive pressure. Therefore, the electric flange fixed ball valve seat has small deformation, short and light operating force, reliable sealing performance and long service life. It is especially suitable for occasions with main pressure and large caliber.

10 Reasons for Excessive Pump Vibration

Abnormal vibration of the pump is an important indicator to evaluate whether the quality of the pump is reliable. There are many reasons for the vibration of multi-stage pumps, such as the influence of water flow conditions, the complexity of fluid motion, dynamic and static balance, high-speed rotating parts, etc., which may affect the stability of the pump. Let's give you a comprehensive analysis of the reasons for the vibration of the pump. 10 Causes of Vibration:
