As one of the core technologies in the pharmaceutical industry, pharmaceutical production processes are of great significance for ensuring drug quality, improving production efficiency, and reducing production costs. Reactor water filtration and slag discharge butterfly valves play a key role in optimizing pharmaceutical production processes. Their introduction perfectly solves user problems and also contributes to national energy conservation and emission reduction.

[0003] The traditional method of slag discharge is to first install a shut-off valve at the outlet of the reactor, then install a set of filters, and then install multiple shut-off valves to complete the filtration and separation of coarse materials. Since the traditional process equipment occupies a large space, the subsequent slag discharge needs to be manually removed. Not only is the process complicated and inefficient, it requires a lot of manpower and also causes pollution. For this reason, we provide a reactor water filtration and slag discharge butterfly valve. Utility Model Content

[0016] 3. This utility model adopts a hollow conical disc design. The disc is thick on the outside (high) and thin on the inside. The hollow valve shaft hole in the conical disc facilitates the diversion of collected liquid into the central drainage hole. A one-way check device is installed at the bottom of the drainage hole in the middle of the disc to prevent the medium from flowing back into the main pipe through the central drainage hole when cleaning the drainage pipe.

[0017] 4. This utility model utilizes a two-section, sleeve-type valve stem for ease of installation and maintenance. The upper section of the valve stem serves as the water inlet shaft, one end of which connects to the valve disc and utilizes an O-ring-sealed pin key for transmission. The other end passes through a worm gear head / electric actuator pin key for transmission. A rotating universal joint is installed at the end for connecting to an air or water source, connecting to an external inlet pipeline for a cleaning medium source. The upper section of the valve stem serves as the drain shaft, with an O-ring sealing the connection between the valve disc and the other end of the valve body. A limit plate is located at the bottom to prevent the valve disc from moving downward. A bottom cover secures and seals the lower outlet for connection to an external drainage pipeline.
