Abstract

The invention provides a steam sterilization device with control valves. The invention is characterized in that a first control valve is connected at the feed inlet of a sterilization cabin of the sterilization device, a second control valve is arranged at the connection portion between the feed inlet of a cooling cabin of the sterilization device and the discharge port of the sterilization cabin, the three side walls of the first control valve and the second control valve are respectively provided with a first purging air inlet, a second purging air inlet, a third purging air inlet, and a fourth purging air inlet, the purging air inlets are communicated with a flashboard cavity, the first, second, and third purging air inlets are arranged opposite to the side walls, the fourth purging air inlet is arranged on the first side wall and opposite to the third purging air inlet and in a valve cavity, and the fourth purging air inlet is arranged towards the second side wall. According to the invention, the arrangement of purging air inlets can thoroughly remove material particles attached to the flashboard cavity, thus material accumulation in the flashboard cavity is effectively prevented, and the stability of the operation of the control valve is guaranteed.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to a steam sterilizing device for rare medicinal materials such as caterpillar fungus. technical background [0002] Sterilization technology belongs to the basic technology of microbiology, which uses physical and chemical means to kill or remove the vegetative cells and their spores (or spores) of all microorganisms in the culture medium, fermentation equipment or other targets, so as to achieve the purpose of sterility. The thoroughness of the sterilization technique depends on the two parameters of sterilization time and sterilant strength. According to different sterilizing agents, sterilization techniques are mainly divided into chemical reagent sterilization, radiation sterilization, dry heat sterilization, moist heat sterilization and filter sterilization. In practical application, the appropriate sterilization method will be selected according to the different types of objects to be...
