Automatic flowing pipe ore pulp switch valve

Abstract

The invention belongs to the technical field of valves, particularly relates to an automatic flowing pipe ore pulp switch valve. The automatic flowing pipe ore pulp switch valve is characterized by comprising a valve body arranged between an inlet flange pipe and two outlet flange pipes, two execution mechanisms connected with the two ends of the valve body and a control mechanism connected with the two execution mechanisms; the inlet flange pipe is located at the center position of the valve body, the valve body comprises a cylindrical shell, two round flashboards, two round sealing plugs, two valve rods and two valve covers, wherein the two round flashboards and the two round sealing plugs are arranged in the cylindrical shell and arranged to be symmetrical to the central line of the inlet flange pipe, the two valve rods penetrate through the circle centers of the round flashboard and the round sealing plug on the any one side of the central line of the inlet flange pipe, the two valve covers are arranged at the two ends of the two valve rods respectively, and the two valve rods are connected with the two corresponding execution mechanisms respectively. The automatic flowing pipeore pulp switch valve is simple in structure and convenient to operate, it can be always ensured that no ore pump is accumulated in the valve body on one side of an out-service pipe through cooperative movement of the flashboards and the sealing plug on the left side and the right side, and ore pulp is convenient to switch.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to an artesian slurry switching valve. Background technique [0002] In the mineral processing production, in order to reduce the production cost, the ore slurry is transported by gravity as much as possible. When designing the mineral processing plant, the artesian pipe adopts a certain slope design based on experience. If the slope is too large, the investment cost will increase and the wear of the pipeline will increase. Therefore, the pipeline slope design is based on the slurry in the pipeline. It is advisable that the flow rate is greater than the settling flow rate of the slurry. At the same time, in order to avoid pipeline blockage, the cross section of the artesian pipe must be larger than the flow area of ​​the slurry, which is in a non-filled state and the pressure in the pipeline is small. In the process configuration, it is often encountered that one artesian pipe is all...

AI Technical Summary

Problems solved by technology

In the process configuration, it is often encountered that one artesian pipe is allocated to two equipments, and one of the two equipments is working and the other is standby. For example, the traditional gate valve is used for pulp switching, because the flow rate of the pulp in the pipe is low and the pressure Small size, easy to deposit ore slurry near the valve, block the pipeline, and make it difficult to switch the valve freely
