The invention discloses a multi-way valve structure of a PTA (pure terephthalic acid) device, and relates to the field of large valve equipment, the multi-way valve structure comprises a valve body, the upper part of the valve body is provided with a main way, the interior of the valve body is downwards and obliquely provided with a plurality of groups of branch ways towards the periphery, and the inlets of the plurality of groups of branch ways are provided with branch way front frustums; a coaxial valve rod screw is arranged on the outer wall of the valve body in the axial direction of the branch, the valve rod seat is fixed to the outer wall of the valve body through a mounting frame, the valve rod screw is coaxially connected with a valve rod in the direction facing an inlet of the branch, the valve rod extends towards the inlet of the branch to enter the branch, and the front end of the valve rod is connected with a valve rod conical head. A branch rear frustum is arranged on the side, facing the valve rod base, of the valve rod conical head in the branch. The side, on the branch, of the valve body communicates with a branch outlet. The valve body and the pipelines are more convenient to install, meanwhile, the maintenance cost of the valve is greatly reduced, it is guaranteed that the valve body can normally adjust the flow of fluid in all the pipelines, and the sealing performance of the valve body is guaranteed.
Description
technical field [0001] The invention relates to the field of large valve equipment, in particular to a multi-way valve structure of a PTA device. Background technique [0002] The high-pressure feed pump of the dissolution reactor in the refining workshop of the PTA unit uses a multi-way valve system, which is a large-scale valve equipment. [0003] Existing PTA devices often encounter the connection of multiple pipelines combined or multiple pipelines of one pipeline. Most of them are connected by multiple independent valves and multiple three-way fittings. However, this connection method has a large number of valves and three-way connections. , The connection workload is large and the cost is high. At the same time, due to the existence of a large number of valves, the valve maintenance workload and valve maintenance cost are also high. SUMMARY OF THE INVENTION [0004] Based on this, the purpose of the present invention is to provide a multi-way valve structure of a PT...
