Embodiment 1
[0038] see figure 1 and figure 2, the flow measurement and control integrated device includes a valve body, a valve core 2 and a valve stem 8; the valve body includes a water inlet pipe 1a, a valve chamber body 1b, an outlet pipe 1c, and a valve chamber cover 1d, and the valve chamber body 1b is located between the water inlet pipe 1a and Between the water outlet pipes 1c, the valve chamber body 1b and the valve chamber cover 1d form a valve chamber with an open top, and the valve core 2 is installed in the valve chamber; the valve core 2 is provided with a through hole connecting the water inlet pipe 1a and the water outlet pipe 1c. Core 2 includes coil, first electrode 7a, second electrode 7b, lead wire 9; The ends are respectively connected to the first electrode 7a and the second electrode 7b, and the fork rod of the lead wire 9 protrudes from the valve stem 8; the valve stem 8 is located at the top of the valve core 2, and forms a top-opening valve from the valve cavity...
Embodiment 2
[0041] See figure 1 and image 3 , the coil includes an upper coil 3 and a lower coil 4, but compared with Embodiment 1, it lacks an upper magnetic core 5 and a lower magnetic core 6.
Embodiment 3
[0043] See figure 1 and Figure 4 , the valve core 2 includes a magnetic core, the coil includes an upper coil 3 and a lower coil 4, the magnetic core is a lower magnetic core 6, and the lower coil 4 surrounds the lower magnetic core 6, but compared with the embodiment 1, the upper magnetic core 5 is lacking .
