Problems solved by technology

[0003] 1. The rubber valve is often in a state of material during the closing process. The granular water slag will inevitably be caught in the closing part during the sudden closing process. It often happens that the rubber pipe is pierced and the closing is not tight, resulting in corrosion. Pollution of the environment due to the outflow of toxic sewage;
[0004] 2. The granular water slag directly rubs against the rubber pipe during the unloading process. Generally, it needs to be replaced every 2 to 3 months, which increases the production cost and the work intensity of the maintenance personnel.

Abstract

The invention provides a water and granulating slag separating gate valve, and relates to the technical field of valves. The water and granulating slag separating gate valve comprises a valve body. A driving device mounting support and two gate swing supports are connected to the valve body, the driving device mounting support is connected with a driving device, the telescopic end of the driving device is connected with a gate in a hinged mode, the gate comprises a circular arc gate plate, a water stop plate, an overfall gap and two sector plates, and the two sector plates are connected with the corresponding gate swing supports respectively in a hinged mode. The circular arc gate plate is arranged between the two sector plates, the two sides of the circular arc gate plate are fixedly connected with the two sector plates respectively, the water stop plate is arranged between two sector plates and is arranged above the end, far away from the driving device, of the circular arc gate plate, the water stop plate is fixedly connected with the two sector plates and the circular arc gate plate, and the overfall gap is fixedly connected to the water stop plate. The water and granulating slag separating gate valve has an automatic granulating slag and water separating function in the closed state, and thus pollution to the environment by waste water is avoided. The service life is prolonged, production cost is saved, and the working intensity of maintenance personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a special valve for opening or cutting off materials in a transfer system of a blast furnace slag treatment plant in an iron and steel enterprise. Background technique [0002] Because the water in blast furnace slag in iron and steel enterprises is highly corrosive, it must be discharged after special treatment. At present, rubber valves are generally used as special valves for opening or cutting off materials in the transfer system of slag treatment plants; The structure is composed of a funnel-shaped valve body, a rubber pipe fixed on the valve body, a cylinder and a swing nip roller, etc. There are the following defects during use: [0003] 1. The rubber valve is often in a state of material during the closing process. The granular water slag will inevitably be caught in the closing part during the sudden closing process. It often happens that the rubber pipe is pierced and th...
