Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture sewage and drainage, in particular to a valve system for an aquaculture sewage and drainage well and a split butterfly valve used therein. Background Art

[0002] Aquaculture is a vital industry in coastal areas. Due to the high density of aquaculture, residual feed and fish and shrimp feces in the ponds can affect the water quality. Therefore, regular water changes—draining and refilling the ponds—are necessary.

[0003] See also Figure 6 In the field of large-scale aquaculture, in the existing technology, in order to facilitate water changes, a sewage and drainage well is set up near the aquaculture pond. The bottom of the sewage and drainage well is connected to the nearby water area, and the bottom of the aquaculture pond is connected to the sewage and drainage well through a drainage pipe. The drainage pipe is provided with a three-way joint, and the upper end of the three-way joint is connected to a detachable pipe (which can be unplugged). The outlet of the three-way joint is provided with a butterfly valve. When the butterfly valve is opened, drainage can be carried out (when the butterfly valve fails, drainage can also be carried out by unplugging the detachable pipe. The detachable pipe is equivalent to a manual drain valve). The butterfly valve is usually controlled by a motor or a rotary cylinder. When the tide is high, seawater flows back into the sewage and drainage well, and the control components are easily damaged by being immersed in seawater. For the motor, there is also a risk of leakage. Utility Model Content

[0004] To address the shortcomings of the existing technology, the present application provides a valve system for aquaculture sewage and drainage wells. This valve system prevents the drive device connected to the butterfly valve from being immersed in water, thereby increasing the service life of the drive device. Furthermore, this valve system is versatile and adaptable to sewage and drainage wells of various shapes. Correspondingly, this application also provides a split butterfly valve for use in this valve system.

Pneumatic actuators use an air source as power, which is lower in cost than electric and hydraulic actuators, and has a simpler structure, making them easier to operate and maintain.
