Description

Electricity liquid speed is opened, speed is closed lock

Technical field

The utility model relates to a kind of gate, especially a kind ofly can speed opens, gate that speed is closed.

Background technique

At present, sewage treatment works, waterworks channel, expressway hold requirement unlatchings rapidly such as malicious deposition tank, and water is flowed into rapidly, floating debris and the gravel more to the pond bottom sediments, and sand grains, foreign material such as harmful matter are got express developed totally.Or current such as sewage treatment works, river course, shipyard, waterworks require quick closedown, in order to avoid do not had by water logging when too fast.The unlatching of common gate, close usually by the driven by motor screw mandrel, screw pair carries out transmission, or ball drives leading screw, mechanical transmission such as ball auxiliary driving, these transmissions are to be converted into straight line motion by rotatablely moving, and have just obviously increased the transmission distance on the drive path, therefore, the transmission distance, transmission speed is slow, and rotational noise is big, part material is required high, for the occasion that requires quick unlatching, quick closedown, this type of mechanical transmission can't reach at all that speed is opened, speed is closed requirement.

The model utility content

The purpose of this utility model is exactly to solve existing gate can not speed open the problem that speed is closed, and provides a kind of and reaches speed with hydraulic transmission and open the gate that speed is closed.

The technical solution adopted in the utility model is: electric liquid speed is opened, speed is closed lock, it comprises the gate of being made up of flashboard and slideway and drives gate slides up and down the realization fast opening and closing along slideway drive unit, it is characterized in that described drive unit comprises oil cylinder, stacking type hydraulic control check valve, stacked double directional throttle valve, Pilot operated check valve, oil hydraulic pump and the fuel tank that hydraulic oil is housed, oil cylinder, stacking type hydraulic control check valve, stacked double directional throttle valve, lower interface is managed connection successively on the Pilot operated check valve, interface in Pilot operated check valve lower end and oil hydraulic pump, first one-way valve and fuel tank are connected in series successively, and another interface directly is connected in series with fuel tank.

Adopt technique scheme, when needs are opened fast, the primer fluid press pump, hydraulic oil enters the oil cylinder bottom by Pilot operated check valve, stacked double directional throttle valve, stacking type hydraulic control check valve successively, promote to move on the piston, piston will spur on the gate and move, thereby reach the purpose of quick starting gate; When the needs quick closedown, start Pilot operated check valve, hydraulic oil is pressed into from the top of oil cylinder, promotes piston and moves down, and realizes quick closedown.

For to the oil hydraulic pump cooling, be serially connected with pressure switch on the pipeline between Pilot operated check valve and the oil hydraulic pump, the oil cooling service pipe serial connection heat exchanger of oil hydraulic pump, second one-way valve are connected with the oil hydraulic pump inlet duct again; The side ports of pressure switch is connected with the oil cooling service pipe pipe of oil hydraulic pump.

For guaranteeing safety, it is characterized in that pipe is connected with accumulator between described pressure switch and the Pilot operated check valve, be serially connected with three position four-way electromagnetic valve on the pipeline, the side interface serial connection solenoid directional control valve of three position four-way electromagnetic valve is connected with the delivery outlet pipe of three position four-way electromagnetic valve again; The inlet of three position four-way electromagnetic valve is connected with tank tube, is serially connected with relief valve on the pipeline.

In sum, the beneficial effects of the utility model are: because the utility model adopts moving up and down of hydraulic oil cylinder driving gate, therefore can realize opening fast and quick closedown.
