Liq. gas delivery appts. for tanker - prevents entrainment of gas through meter, with throttle in return and control duct

摘要

Appts. delivers liq. gas from a tanker, and consists of a liq. gas pump, gas measurement preventer, counter and press-maintaining valve. The pump is in a delivery duct leading from the supply container to the gas measurement preventer and further via the counter and press.-maintaining valve to the tapping point. A return and control duct with a throttle is connected to a gas pendulum duct, and is connected behind a branch point with a gas measurement preventer duct branch via a float-controlled valve to the preventer, and is connected with a press. maintenance valve duct branch to the press. maintenance valve. The throttle is fitted in the section between the branch point and the gas pendulum duct in the return and control duct, and is set so that the press. maintenance valve closes when the float-controlled valve closes. Entrainment of gas with the liq. being measured is prevented.
