Description

Technical Field

[0001] The utility model relates to the technical field related to sewage treatment, in particular to a three-way valve for sewage treatment. Background Art

[0002] In sewage treatment, valves need to be installed in the pipeline. Traditional valves are mostly two-way valves, three-way valves and multi-way valves.

[0003] After massive searching, it was found that the reference document 1 with the prior art publication number CN212455608U discloses a three-position three-way valve sewage quality separation suction device, including a three-position three-way valve, a first water inlet pipe, a second water inlet pipe, a vacuum suction pipe and a driving device; the three-position three-way valve includes a valve body and a valve core, the valve body is hollow inside, the valve core is arranged inside the valve body, the valve body includes a first water inlet, a second water inlet and a water outlet connected to the interior thereof, the valve core includes a first water outlet, a second water outlet and a third water outlet connected to the interior of the valve body, the first water outlet, the second water outlet and the third water outlet are connected to each other inside the valve core; the first water inlet pipe, the second water inlet pipe and the vacuum suction pipe are respectively connected to the first water inlet, the second water inlet and the water outlet, and the driving device is connected to the valve core. The advantages are: by setting a three-position three-way valve, the three functions of sucking black water, sucking gray water and closing the vacuum suction pipe can be realized, meeting the needs of collecting sewage according to quality, avoiding the problems of large size and complex control of double valves, and greatly reducing the cost of the suction device.

[0004] Or as Figure 1 In the reference document 2 shown, valve plates are installed on the water inlet, the first water outlet and the second water outlet to perform on-off processing on the three respectively.

[0005] In summary, the existing valve body structure realizes on-off switching through multiple valve plates, which is relatively cumbersome to use; in addition, the sealing performance of the valve plate during on-off switching is relatively general.

[0006] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a three-way valve for sewage treatment to make it more valuable for industrial use. Utility Model Content
