    摘要: A quick-acting valve 1 having metering relief is used in particular for oxygen lances, wherein the actual sealing body 10 inside the valve tube 2 has a two-part design and accommodates the valve spring 8 with the housing parts 16 and 17 of the spring. The gas is conducted around the sealing body 10, so that the gas pressure cannot have an effect on the actuation by way of the hand lever 3. The rear housing part 17, which is located behind the front housing part 16 can be displaced inside the front housing part 16, and has a flow-promoting design, being displaced against the force of the valve spring 8, and specifically with the help of the hand lever 3, so that it now can be actuated independently of the gas pressure with precise metering control.
