Gate

Abstract

The invention discloses a gate which comprises a gate body (9) and a gate frame (10). The gate body (9) is mounted in the gate frame (10); the gate body (9) is connected with an on-off device for controlling on-off of the gate body (9); an overflow pipe (8) communicated with both sides of the gate is arranged in the gate body (9); a valve (11) for opening and closing the overflow pipe (8) is arranged on an opening at one side of the overflow pipe (8). Watertight rubber strips are mounted on both surfaces of the steel overhaul gate disclosed by the invention, so that bidirectional compression on the gate can be achieved; by adopting a novel discharge device, the problem of an excessively large friction force when the gate is opened and closed is solved; the gate is safe and reliable to open and close; discharging capacity can be regulated; after overhaul on downstream equipment is completed, impact of water flow to the downstream equipment is effectively reduced.

Description

technical field [0001] The invention belongs to a water treatment device, and mainly relates to a water level control and a steel overhaul gate for blocking upstream incoming water and providing an overhaul environment when water treatment equipment is maintained. Background technique [0002] The gate acts as a water level control device. Commonly used gates can be divided into cast iron gates and steel gates according to their materials. Due to the high strength and light weight of steel gates. The structure is simple and does not require molds, and the size is flexible. Therefore, steel gates are the most commonly used gates in the water treatment industry. The steel gate is pressed against the gate frame by the rubber strips around the gate body under the action of positive water pressure, so as to achieve the sealing effect. If the water pressure direction is reversed, the rubber strip cannot be pressed tightly with the door frame, and the gate will leak, which canno...

AI Technical Summary

Problems solved by technology

If the water pressure direction is reversed, the rubber strip cannot be pressed against the door frame, and the gate will leak, which cannot achieve the water-stop effect

If rubber strips are installed on both sides of the gate, the friction between the rubber strip and the gate frame will be too large when the gate is opened and closed under the action of water pressure, and the equipment will be easily damaged and difficult to use normally.

In addition, after the maintenance of the downstream equipment is completed, when the traditional maintenance gate is opened, the upstream water flows down instantly, which may impact the downstream water treatment equipment, cause certain damage to the equipment, and pose a safety hazard to the operators.
