Description

Technical Field

[0001] The invention relates to the technical field of hemispherical valves, and more specifically to a novel intelligent eccentric hemispherical valve. Background Art

[0002] The eccentric semi-ball valve is a relatively new type of ball valve, which is widely used in working conditions requiring strict shut-off such as petroleum, chemical industry, and urban water supply and drainage. The connection between the semi-valve ball and the valve stem in the existing eccentric semi-ball valve adopts a nested connection. Since it needs to be assembled manually, each valve has functions such as flow monitoring and pressure monitoring, and transmits the monitoring data to the control system. Mobile phones and other handheld devices are connected to the control system for viewing. When the eccentric semi-ball valve body is damaged, the eccentric semi-ball valve body needs to be disassembled for replacement and maintenance. However, when replacing and maintaining it, the sealing cover needs to be disassembled, and then the rotating support inside the bottom sealing block needs to be disassembled before the eccentric semi-ball valve body can be disassembled. The operation is relatively cumbersome, and it is inconvenient to replace and maintain the eccentric semi-ball valve body. Utility Model Content
