What is the structural principle of electric ball valve?

The electric ball valve is a type of pipeline pressure property element that is controlled by the industry's fully automated process, and is usually applied to a remote switching operation of a pipeline medium. What is the structural principle of the electric ball valve? The following will explain it in detail.
The structure of the electric ball valve is simple, it is composed of only a few parts and components, and the data is cost-saving; the occupied area is small, the weight is light, the installation standard is small, the torque of the driving force is small, and the pressure regulating control valve is convenient and quick to operate. Rotation of ninety degrees can quickly switch; and at the same time also has a very good flow regulation effect and seal sealing special performance, in the role of large, medium diameter, medium and low pressure range, electric ball valve as the dominant valve status. When the electric ball valve is in the fully open position, the thickness of the butterfly plate becomes the unique resistance when the medium flows through the valve body, so the pressure generated by this valve drops very little, so it has a good flow maintaining characteristic.
Electric ball valve has two types of seals: elastic seal type and metal seal type. Elastic sealing type valve, the sealing ring can be mounted on the valve body or attached to the butterfly plate. Valves with metal seals generally have longer service life than resilient seals, but they are not easy to achieve a complete seal. Metal seals are able to adapt to very high field temperatures. Elastic seals have the disadvantage of being temperature limited.
If it is required that the electric ball valve be used for maintaining the flow rate, the size and type of the valve should be precisely selected. The structural principle of the electric ball valve is particularly suitable for the manufacture of large-diameter valves. The electric ball valve has not only been widely used in ordinary industries such as the petroleum industry and chemical industry, but also applied to the cooling water operation system of major thermal power stations.
The commonly used electric ball valve has two types of electric ball valve of the clip type and electric ball valve of the flange type. The clip-type electric ball valve uses a double-headed bolt to connect the valve to the middle of two pipe flanges. The flange-type electric ball valve uses a flange on the valve, and the two upper flanges of the valve are bolted together by bolts. The flange of the pipe. The strength property of the valve refers to the ability of the valve to withstand media extrusion. The valve is a mechanized category subject to internal pressure, so it must have sufficient strength and hardness to ensure long-term application without breaking or deforming.
