Abstract
The invention discloses a gate valve with rubber bushings. The gate valve with the rubber bushings comprises a valve body and a gate plate. A medium conveying channel and a gate plate movable channel are formed in the valve body, wherein the gate plate movable channel is perpendicular to the medium conveying channel. The gate plate is arranged in the gate plate movable channel. The upper portion of the valve body is connected with an operation mechanism. The two annular rubber bushings are embedded in the portions, located on the two sides of the gate plate, of the medium conveying channel of the valve body. An outer chamfer is arranged on the outer side face of the end, close to the gate plate, of each rubber bushing. A shoulder is arranged at the other end, far away from the gate plate, of each rubber bushing and abuts against the end face of the valve body. A metal ring is glued to the middle of each rubber bushing. When the gate valve is closed, the gate plate is moved downwards, the gate plate squeezes the two rubber bushings to enable the rubber bushings to be opened, so that the end faces, close to the gate plate, of the two rubber bushings are tightly attached to the two side faces of the gate plate. When the gate valve is opened, the gate plate is moved upwards, the gate plate disengages from the two rubber bushings, the opposite end faces of the two rubber bushings abut against each other. By the adoption of the gate valve with the rubber bushings, the abrasion and the corrosion of the valve body can be avoided, the airtightness, existing when the gate valve, of the gate valve is closed is improved, and the service life of the gate valve is prolonged.
