Problems solved by technology

[0002] In the field of chemical industry, it is often necessary to perform a proportioning reaction on some fluids. When adding materials, it is necessary to put raw materials in a certain proportion. These fluid raw materials must be allowed to flow in at a certain rate to ensure the proportioning of various raw materials. The traditional valve control will cause a large error in the control. With the flow of the fluid, the flow velocity and pressure in the pipeline are changing at any time. In order to improve the accuracy of the ratio, a feedback throttling device is deliberately designed to improve the above. question

Abstract

The invention relates to the field of chemical equipment, in particular to a feedback throttling device. The feedback throttling device comprises a valve body. The left side of the valve body is connected with a left outer flange. A right outer flange is connected to the right side of the valve body. A left inclined hole which gradually decreases from left to right is formed in the left outer flange. The left inclined hole is communicated with an inlet formed in the valve body. An inclined hole which gradually decreases from left to right is formed in the right outer flange. The inclined holeis communicated with an outlet formed in the valve body. According to the feedback throttling device, the flow rate and the flow of fluid in a pipeline can be uniformly controlled through effective self-feedback adjustment, so that the accuracy of raw material proportioning is ensured; and meanwhile, a pipeline fixing device is additionally arranged, so that the pipeline and the valve can be effectively fixed together, the phenomena of pipeline falling, valve leakage and the like can be effectively prevented, and meanwhile, the flow of the valve can be conveniently controlled so as to meet therequirements of different processes.
