Furthermore, the flow area of the water outlet of the valve body is 23% larger than that of the water inlet.
Furthermore, the outlet of the valve body is a square outlet, and an arc is processed on one side of the square outlet, which is far away from the hand wheel.
Furthermore, an energy dissipation ridge is arranged on one side, facing the valve body, of the valve cover.
Compared with the prior art, the utility model following beneficial effect has:
one, work as the utility model discloses when being in half the open mode, water gets into through the water outlet discharge through the water inlet, and the effect through the valve plate has increased the resistance that rivers flow and has reduced the kinetic energy of water. The utility model discloses a water inlet and pipe connection, the direct drainage of delivery port will further reduce the kinetic energy of water through the mode of this kind of reverse play water, can avoid to a great extent like this because the kinetic energy of water is too big to cause the harm brought to the washing away of irrigating the field.
Secondly, the utility model discloses a problem that the paddy field was washed has been solved to simple structure, and the cost is with low costs.
