Detailed Description
The utility model is described in further detail with reference to the figures and specific embodiments.
The utility model provides a reduce arrangement structure of surge tower height, includes surge tower 3, and the lower part of surge tower 3 is linked together through connecting pipe 2 and diversion tunnel 1, and the lower part of surge tower 3 is equipped with the outlet pipe 4 that communicates to tank 7 in the different sides with 1 position in diversion tunnel, is equipped with relief valve 5 on the outlet pipe 4.
In this embodiment: the drain pipe 4 is provided with an inspection valve 6 between the pressure release valve 5 and the pressure regulating tower 3.
In this embodiment: the service valve 6 is a gate valve or an eccentric half ball valve.
In this embodiment: the overflowing diameter of the service valve 6 is not less than that of the pressure relief valve 5.
In this embodiment: the water storage tank 7 is provided with a drain pipe 8.
In this embodiment: and a water level sensor 9 is arranged on the inner side wall of the pressure regulating tower 3, and the water level sensor 9 is connected to an alarm 10 and a display 11 through cables.
When the unit is in a load shedding state, water in the diversion tunnel 1 can flow to the surge tower 3. When the pressure regulating tower water level surpassed 5 opening water levels of relief valve, 5 valves of relief valve opened, will gush into the rivers in the pressure regulating tower and excrete in reservoir 7 through outlet pipe 4 to reach the purpose that reduces the highest surge water level in the pressure regulating tower 3. Meanwhile, the water storage tank 7 is provided with a drain pipe 8, and the drain pipe 8 is connected with an external river channel or ditch for discharging water in the water storage tank 7 at a small flow rate. When the water level of the pressure regulating tower is reduced to the closing water level of the pressure relief valve 5, the valve of the pressure relief valve 5 is closed, and the water leakage in the pressure regulating tower 3 is avoided.
