PORTABLE GAS SPRAYER FOR CHECKING OF GAS LEAK DETECTOR

摘要

The present invention relates to a portable gas injector that is simple to carry and use so that a small amount of gas can be artificially injected to check the operation state of a gas detector or a gas detector that is operating by detecting a gas leak. A coupling member having a fastening means mechanically connected to the container connecting portion formed on the upper surface of the gas container, and having a hole formed at a position corresponding to the gas injection hole formed at the center of the container connecting portion, and fixed to the coupling member by fixing means. On the other hand, the valve body portion is formed in the close contact with the gas inlet through the hole and the handle is formed to control the gas flow on one side, and the pipe-shaped extension portion and the extension portion formed with the through-hole mounted on the gas outlet portion of the valve body portion It characterized in that it comprises a nozzle that is coupled to one side Has the advantage of being able to add an extension of the injector which is variable to provide a portable gas injector for injecting a test gas leak alarm readily gas from any location in the gas leak detectors are installed.
