Embodiment 1
[0016] like figure 1 As shown, a coaxial two-way vertical base meter with a valve is suitable for small-diameter smart water meters, including a water meter housing 1, a filter screen 3, a diversion inclined hole 4, a diversion chamber 5, a rotor impeller 6, a guide Flow chamber water outlet 9 and control valve 10. The control valve 10 can be selected from a ball valve, a pilot valve or a stop valve.
[0017] A water meter water inlet 2 is provided at the bottom of the water meter housing 1, and a water meter water outlet 11 is provided at the top. Water meter water inlet 2, filter screen 3, diversion inclined hole 4, diversion chamber 5, rotor impeller 6, diversion chamber water outlet 9, control valve 10 and water meter outlet 11 are arranged in sequence from bottom to top, and the central axis same.
[0018] The upper part of the rotor-type impeller 6 is inlaid with a stainless steel sheet 7, and the side of the water meter housing 1 is fixed with a metal detection senso...
Embodiment 2
[0021] like figure 2 As shown, a coaxial two-way vertical base meter with a valve is suitable for large-diameter smart water meters, including a water meter casing 1 , a screw-wing impeller 12 , an impeller bracket 13 and a control valve 10 . The control valve 10 can be selected from a ball valve, a pilot valve or a stop valve.
[0022] A water meter water inlet 2 is provided at the bottom of the water meter housing 1, and a water meter water outlet 11 is provided at the top. The water meter water inlet 2, the impeller bracket 13, the screw-wing impeller 12, the control valve 10 and the water meter water outlet 11 are arranged sequentially from bottom to top, and the central axes are the same. The base meter has large flow rate and small pressure loss, and is suitable for large-diameter water meters.
[0023] The upper part of the screw-wing impeller 12 is inlaid with a stainless steel sheet 7, and the side of the water meter housing 1 is fixed with a metal detection sensor...
