Therefore, it is necessary to set up water sampling equipment on ships to collect water samples, and then analyze and monitor the water pollution through laboratories. Existing water sampling devices, such as the sewage treatment pond sampling device disclosed in patent publication number CN223192630U, include a device frame, air pump, sampling tray, sampling bottle and air intake branch pipe. A solenoid valve is installed at the connection between the air intake branch pipe and the adapter, and a one-way valve is installed at the bottom of the sampling bottle.

The multi-channel valve group has ten water inlet interfaces and can make the ten water sampling pipelines independent of each other, preventing liquid cross-contamination between the sampling water channels, realizing individual sampling of multiple water samples, with a high degree of integration, small space occupation, and stable water sampling, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel valve assembly for water sample collection, comprising a base, a plurality of water inlet ports on one side wall of the base, a water outlet port on the other side wall of the base, a solenoid valve at each position corresponding to a water inlet port on the base, a water inlet channel at each position of a water inlet port on the base, and each water inlet port being connected to its corresponding solenoid valve through the water inlet channel, and each solenoid valve having a one-way valve connected to its outlet; a valve seat on the base, a manifold channel being formed inside the valve seat, and a connecting hole at the bottom of the valve seat being connected to the manifold channel, and each one-way valve having its outlet connected to the manifold channel of the valve seat; a water outlet channel at each position of a water outlet port on the base, and the water outlet channel being connected to the manifold channel through the connecting hole.

[0005] Furthermore, the water inlet and water outlet are arranged opposite to each other, and the base is provided with ten water inlet ports.

[0006] Furthermore, the valve seat has a square tube structure, and both ends of the valve seat are equipped with sealing plugs.

[0007] Furthermore, the base is also equipped with a sealing cover, and the solenoid valve, check valve and valve seat are all located inside the sealing cover; the base is also provided with connection holes for installation and fixing.

[0008] Furthermore, the valve seat is also provided with wiring terminals for wiring the solenoid valve, and the sealing cover is provided with a waterproof connector.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This multi-channel valve group for water sampling has ten inlet ports for water sampling and one outlet port for water extraction. The solenoid valve and check valve make each water sampling pipeline independent of each other, and can prevent liquid cross-contamination between the sampling water channels. It can realize the individual sampling of multiple water samples, has a high degree of integration, occupies little space, and provides stable water sampling. Attached Figure Description
