Description

Technical Field

[0001] The utility model relates to the technical field of seawater desalination, in particular to a two-way valve for seawater desalination with an anti-blocking structure. Background Technique

[0002] Seawater desalination is to produce fresh water by desalinating seawater. It is an open-source incremental technology for water resource utilization, which can increase the total amount of fresh water, and is not affected by time, space and climate. It can ensure stable water supply for coastal residents' drinking water and industrial boiler make-up water. During the process of seawater desalination, a two-way valve is often required to control the fluid device.

[0003] The "valve for seawater desalination with anti-blocking function" disclosed in its application number "202221935152.7" "comprises a valve body, a fixed shell and a telescopic rod. An anti-blocking structure is installed on one side inside the valve body. The anti-blocking structure includes a motor, a rotating shaft and a stirring frame. The motor is installed at the top of the valve body. The bottom end of the motor is fixed with a rotating shaft, and stirring frames are fixed on both sides of the rotating shaft. A fixed shell is fixed at the top of the valve body. A guiding structure is arranged inside the fixed shell. A reinforcing structure is arranged inside the support frame fixed at the top of the fixed shell. The telescopic rod is threadedly connected inside the fixed shell. The top end of the telescopic rod is fixed with a turntable, and the bottom end of the telescopic rod is movably connected with a valve core". In the utility model, the inside of the valve body can be prevented from being blocked by setting an anti-blocking structure. When in use, the inside of the valve body will be flowed through by seawater. Seawater contains a large amount of salt. After long-term accumulation, the inside of the valve body may be blocked. At this time, start the motor to rotate and drive the rotating shaft to rotate. When the rotating shaft rotates, it drives the stirring frame to swing. The stirring frame stirs the inside of the valve body through swinging, so that the inside of the valve body will not accumulate salt, realizing the anti-blocking of the inside of the valve body.

[0004] However, the above method still has the following defects: The inside of the valve body can be cleaned by driving the clamping plate frame by a motor, but the impurities in the seawater will directly reach the seawater pipeline, and it is difficult to remove impurities from the seawater and filter them to keep the inside of the pipeline clean, which easily leads to pipeline blockage.
