Claims

[Scope of Claim for Utility Model Registration] (1) The water flow control surface that can be submerged in the lower water tank of the cooling tower has a toilet seat opening on the top wall through which the main water flow passes, and a suction pipe connection port on the side wall. A negative pressure prevention hole is provided in another part of the side wall through which a small branch flow passes through to the lower spine, and a valve plate that opens and closes in contact with and separates from the valve seat is provided in the other part of the side wall. 1. An air suction prevention device in a lower water tank of a cooling tower, characterized in that the device is integrally fixed to a float spaced apart from each other and is moved up and down depending on the water level in the lower water tank. (2) The load pressure prevention hole is of a variable water flow control type, and the negative pressure prevention hole of this variable water flow control type has a large number of vertical holes bored in parallel near the bottom of the side wall of the water flow control box. , a cooling tower according to claim 1, characterized in that a common water flow control plate having a size sufficient to cover a large number of these vertical holes is provided so as to be slidable up and down. Air suction prevention device in the lower water tank.
