Further, the aperture of through hole is 2-2.5 times of shaft diameter.
Further, the end of watermeter shell connects with the bottom face of seal closure cylinder, between watermeter shell and seal closure cylinder
Joint pass through sealing clamp be tightly connected.
The beneficial effects of the utility model：
The water meter of the utility model between counter and rotary blade by being arranged flared water fender, so that water blocking
Space between plate and counter forms sealing structure, and when hydraulic pressure rises, water flow enters counting along the through hole of water fender
In device space, when the air pressure between hydraulic pressure and counter is identical, the water surface not will rise, due to water fender and seal closure cylinder cylinder top
Between there are air so that having certain distance between the cylinder top of the counter top and seal closure cylinder of the water surface and water meter, in turn
So that will not become larger due to volume when winter water freezing counter and seal closure cylinder bursting.
