ボンベ内酸素の定量取出し器。[Scope of claim for utility model registration] Quantitative extractor 5 for oxygen in oxygen inhalation cylinder 1
In the body 29 of the main body 29, the outlet hole 37 of the outlet cylinder 36 is communicated with the inlet hole 31 via the pressure reducing valve chamber 32, the working chamber 33, the throttle passage 34, and the spring chamber 35. The body 44 is configured to be able to be pressed downstream by a valve-closing return spring 45 and come into close contact with the pressure reducing valve seat 46, and the pressure receiving actuating body 4 is placed between the actuating chamber 33 and the spring chamber 35.
The pressure receiving actuating body 48 returns the pressure reducing valve body 44 to the closing position via the transmission device 50 by being pressed upstream by a valve opening balancing spring 49 mounted in the spring chamber 35. The pressure reducing valve body 44 is pressed toward the valve opening side against the spring 45, whereas the pressure in the working chamber 33 is pressed downstream against the valve opening balancing spring 49, so that the pressure reducing valve body 44 is pressed toward the valve closing side. The outlet tube 36 is configured to be pressed toward the valve closing side by a return spring 45, and the outlet tube 36 is fitted into the spring chamber 35 in an airtight sliding and rotatable manner to support the base end 49a of the valve opening balancing spring 49. The meter for taking out oxygen in a cylinder for oxygen inhalation is characterized in that the device is configured to be adjusted and moved in the direction of adjusting the tension of the balancing spring 49 for opening the valve by means of an adjusting screw 52.
