Description

Technical Field

[0001] The invention belongs to the technical field of sampling valves and relates to a sampling valve, in particular to an integrated full-automatic cleaning and sterilizing sampling valve. Background Art

[0002] In the production process of food or medicine, the production is coordinated by tank structure and transported through pipelines. The demand for product quality control determines that sampling valves must be installed on equipment and pipelines to facilitate sampling and ensure timely testing and analysis. Among them, microbial sampling and inspection of raw materials, semi-finished products, and finished products is an important means to monitor the microorganisms of products and improve the level of food hygiene management.

[0003] Sampling valves are roughly divided into three categories according to their structure and working principle: flange clamp valves, double opening valves, and sampling valves with insulation jackets. In the food industry, sampling valves are simply divided into ordinary sampling valves and sanitary sampling valves according to their sanitary performance.

[0004] The sterilization of the valve body requires a complete set of supporting valves, pipelines and public energy connections, which affects the spatial layout and project operation and production costs. In addition, multiple sampling schemes are mostly to provide separate steam pipelines to connect sampling valves for separate sterilization. The high steam temperature has a greater impact on the material and poses a potential risk to product quality.

[0005] Therefore, we propose an integrated fully automatic cleaning and sterilization sampling valve, which is easy to disassemble and assemble, can quickly switch between sampling and material guiding, has stable conveying, and can automatically perform sampling and high-temperature steam cleaning and sterilization.

[0075] Similarly, high-temperature steam may be injected to clean and sterilize the feed end piece 2 and the electric control valve 1 with high-temperature steam.

[0076] In summary, the material is diverted by the cooperation of the electric control valve 1 and the feed end piece 2, and the switch and flow of the diversion can be controlled, so that the transportation is stable;

[0077] The feed end piece 2, the connecting cylinder piece 4 and the discharge end piece 7 cooperate to form a detachable flow guide channel for easy assembly;
