Oil gas recovery break-away valve

Abstract

The invention discloses an oil gas recovery break-away valve which comprises a first valve body and a second valve body. A first magnet and a second magnet are arranged on the first valve body and the second valve body correspondingly, when the first valve body and the second valve body are in butt joint, a gas path and an oil path in the first valve body and the second valve body communicate with each other, and the first magnet and the second magnet are tightly attracted. When the first valve body and the second valve body are separated, the first magnet and the second magnet are not subjected to external force such as extrusion and friction and are not damaged, so that the oil gas recovery break-away valve is long in service life, the first magnet and the second magnet are attracted again when the oil gas recovery break-away valve is used again, and maintenance is very convenient. Due to the fact that a gas path valve element in linkage with a first valve element is arranged in a first valve seat, when the first valve body and the second valve body are separated, the first valve element can seal the oil path in the first valve body, and the gas path valve element can seal the gas path, so that the oil path and the gas path in the first valve body are sealed at the same time, and oil leakage can be prevented; and meanwhile, pollution or danger caused by leakage of collected volatile gas is prevented.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an oil gas recovery breakaway valve. Background technique [0002] In the gas station, the break-off valve is an emergency release device, which is one of the most important parts of the fuel tanker. The valve involves many safety issues at the same time. First of all, during use, the breakaway valve must be able to disconnect under a certain range of tension, so as to avoid the danger of breaking the fuel pipe of the fuel dispenser due to high tension. For example, When the fuel gun is not removed from the vehicle, the driver makes a misjudgment and drives the vehicle. At this time, the break valve is disconnected, which can prevent fuel leakage caused by the fuel pipe being broken; secondly, when the pulling force is less than the pulling force range , can work stably and safely, and will not affect use or leak due to frequent disconnection. [0003] The control of the breakin...
