Description

Technical Field

[0001] The utility model belongs to the technical field of experimental high-temperature and high-pressure polymerization, and particularly relates to a discharge valve structure. Background Art

[0002] High-temperature and high-pressure polymerization experimental devices are usually equipment used to conduct polymerization experiments under pressurized conditions. Such devices are often used in research fields such as high-pressure polymerization reactions and high-pressure polymer synthesis, which include reactors, temperature control systems, stirring systems, vacuum systems, and safety systems, and the containers containing the reactants are usually made of high-strength, high-pressure resistant materials, such as stainless steel, duplex steel, Hastelloy, etc. The container usually has good sealing properties to prevent leakage of the reactants, and high-pressure polymerization reactions usually need to be carried out under specific temperature conditions. Therefore, high-pressure polymerization experimental devices are usually equipped with a temperature control system to ensure the stability of the reaction temperature. In order to maintain uniform mixing of the reactants, a stirring system is usually required in the high-pressure container, and an observation sampling system is used to monitor and record the reaction process. This may include sensors, cameras, or other monitoring equipment. In addition, sometimes it is also necessary to sample the reactants for subsequent analysis. Since high-pressure conditions may bring some safety risks, high-pressure polymerization experimental devices are usually equipped with safety systems to ensure the safety of experimental operators.

[0003] The problem with the prior art is that when a discharge valve is used to transport the melt, when a large number of impurities appear inside the melt, the overall quality of the melt will be affected, so corresponding filtering measures are required, and it is necessary to ensure that during the filtering process, leakage is prevented from occurring at the connection position between the discharge valve and the external connection equipment.
