Abstract

The invention discloses an inflatable isolating valve. A double-layer grid (7) is fixedly connected on a charging chute (8); an inflatable rubber pocket (4) is filled inside the chute and fixed; and an inflating valve (1) is arranged on the inflatable rubber pocket (4). Compared with the prior art, the inflatable isolating valve avoids the phenomenon that an inserting board cannot be inserted tightly because of scaling in the charging chute, namely untightly closed valve. Furthermore, as the 'inserting board' of the isolating valve adopts the inflatable rubber pocket, and the inserting board is deflated when the inserting board is placed in and taken out so as to reduce friction, the inserting board can be placed in and taken out easily and is convenient for cleaning, so that the service life of the valve can be greatly prolonged. The inflatable isolating valve not only reduces labor intensity of operators, but also greatly reduces the manufacturing cost.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical engineering valves, and in particular relates to a plug-in isolation valve. Background technique: [0002] In the process of continuous production (such as alumina production), it is often necessary to change the process during the transportation of materials containing suspension slurry, that is, to close the valve in the direction where the material is flowing, and to open the valve in the other direction, so that Material changes direction of flow. At present, in production, gate valves are generally installed on the feed chute, and the flow direction of the material is changed by manually switching the gate valves. However, due to the large size of the gate valve and the infrequent switching, the screw of the valve body will rust after a long time. In addition, due to the high viscosity of the material containing the suspension slurry, it is easy to scale and scar on the valve, resulting ...
