Pneumatic baffle valve for aseptic steam freeze dryer

Abstract

The invention relates to a pneumatic baffle valve for an aseptic steam freeze dryer, which comprises an executing mechanism, a valve cap, a valve rod, a valve body, a valve plate and a coupling arranged in the inner cavity of the valve body, wherein the coupling is fixedly connected with one side end face of the valve plate; the valve body is provided with a first outlet and a second outlet; the first outlet is vertical to the second outlet; the valve cap is connected with a flange at the front end of the valve body; the central position of the end face of the valve cap is provided with a through hole; and the executing mechanism is an air cylinder and is fixedly connected with the valve cap. The pneumatic baffle valve for the aseptic steam freeze dyer has the advantages of small switch torque, small configured executing mechanism, stable work, compact structure, reliable seal, long service life, high promotion, great admittance, economic use and the like.

Description

technical field [0001] The invention relates to pharmaceutical machinery, in particular to a pneumatic baffle valve for a steam aseptic freeze dryer. Background technique [0002] At present, manual ball valves or pneumatic ball valves are usually used in the vacuum system of steam aseptic freeze-dryers to connect the condenser and the vacuum power unit; however, the existing manual ball valves or pneumatic ball valves have the following problems, which affect the performance of the freeze-dryer Normal use: [0003] 1. The inlet and outlet of the existing manual ball valve or pneumatic ball valve cannot be vertical, which will cause inconvenience to the construction of the operator during the assembly process of the freeze dryer (mainly reflected in the piping project), thus consuming a lot of man-hours but unable to achieve a perfect appearance design Require; [0004] 2.

Problems solved by technology

[0002] At present, manual ball valves or pneumatic ball valves are usually used in the vacuum system of steam aseptic freeze-dryers to connect the condenser and the vacuum power unit; however, the existing manual ball valves or pneumatic ball valves have the following problems, which affect the performance of the freeze-dryer Normal use:

[0003] 1. The inlet and outlet of the existing manual ball valve or pneumatic ball valve cannot be vertical, which will cause inconvenience to the construction of the operator during the assembly process of the freeze dryer (mainly reflected in the piping project), thus consuming a lot of man-hours but unable to achieve a perfect appearance design Require;

[0004] 2. The existing manual ball valves or pneumatic ball valves lack corresponding supporting actuators, which makes their opening and closing control greatly affected by other human or environmental factors. For steam aseptic freeze dryers, the vacuum performance requirements for each component are close to The harsh medical machinery and large-scale equipment obviously do not match, thus virtually increasing the risk factor in the operation and production process of the steam sterile freeze dryer;

[0005] 3. The service life of the existing manual ball valve or pneumatic ball valve is not long, and the possibility of maintenance and parts damage is very common, which requires maintenance personnel to enter the equipment room of the steam sterile freeze dryer after such a situation occurs For disassembly and replacement, however, for the steam aseptic freeze dryer with very stable and strict production environment requirements, such situations should be avoided as much as possible
