    专利说明:

    This invention relates to sterilizers and can be used in the medical industry. A sterilizer is known which contains a working chamber, a heating element located in its lower part, and an air vent valve 1. However, this sterilizer does not have sufficient reliability of the air removal device. The aim of the invention is to ensure more complete removal of air and sterilization quality. The goal is achieved by the fact that the air exhaust valve is connected to the lower part of the working chamber and consists of a body, a temperature-sensitive element installed inside it into a cylinder, the cross section of which is smaller than the internal cross section of the body and the valve that is movable to control the air outlet. The drawing shows the sterilizer. The sterilizer consists of a casing 1 enclosed in a shell 2 of the working chamber 3 closed with an end side by a door 4. Objects 5 are placed on the plates 6 in the sterilizer. The guiding plates 7 are located in the sterilizer for appropriate direction of water. is evaporated by means of tubular heating element 8. Temperature regulator 9 is installed in chamber 3. A manometer 10 is connected to the chamber 3 of the sterilizer. A vent valve 11 is located adjacent to the bottom of the working chamber 3 of the sterilizer and below the bottommost plate 6 to accommodate the objects to be sterilized. adjustable with respect to the body valve 14 seat 11. The valve body 12 is provided with a valve needle cooperating with the seat 14. The cross section of the thermosensitive element 13 is smaller than the internal cross section of the body 12 of the valve 11, so that the thermo sensitive element 13 is completely washed by air or steam. A safety valve 15 and an iO pressure gauge are connected to the working chamber 3 by means of a pipeline. The safety valve 15 is connected via an intermediate steam discharge valve 16 to the discharge pipe II of the air vent valve 11.
    Sterilizer works steaduishm abraeom.
    When the heating element 8 creates steam in the working chamber 3, the steam attempts to penetrate the air through the valve. The sensing element 13 is heated more and more by air, and later by an air-steam mixture, and expands. The needle 18 of the valve 11 approaches the seat 14 and reduces the cross section of the outgoing flow. The valve seat 14 is adjusted so that when the thermosensitive element 13 of the valve starts to be washed only with steam, the valve 11 closes.
    After sterilization is completed, the heating element 8 is turned off and the temperature in the working chamber 3, as well. the same in the vent valve 11 is reduced. The sensing element 13 is compressed, the valve 11 is opened and the SEARCH pressure equalization between the working chamber and the atmosphere.
    This sterilizer allows you to improve the quality of sterilization and provide a more complete removal of air,
