Novel gate opening/ closing device of hydraulic model test
The invention relates to a flat inlet valve model for hydraulic test. A novel gate opening/ closing device of hydraulic model test mainly comprises a gate opening/ closing cross beam, a gate board, a lead screw and a T-shaped flange, wherein the T-shaped flange passes through a screw hole I and is fixedly connected with the gate opening/ closing cross beam; the lead screw passes through the T-shaped flange and is in threaded connection with the T-shaped flange; a concave hole is formed in the position of the gate board, corresponding to the lead screw; the lead screw is inserted into the concave hole and is in threaded connection with the concave hole; a gasket is arranged in the concave hole; a nut head is connected with the gasket; a fine lead screw is vertically fixedly connected to the gasket. The device is easily processed, convenient to mount and overhaul during use, flexible and accurate to open/ close and lift, and small in error range. Compared with the prior art, the device has the advantages of being simple in structure, reasonable in design, nice in appearance, and long in service life.
