Problems solved by technology

[0003] In particular, the gas collection pipes (gas phase pipes) of all loading and unloading arms are connected to the oil and gas recovery system. When some loading and unloading arms are in operation, the oil and gas flow back from the gas collecting pipes of idle loading and unloading arms and are directly discharged to the atmosphere, resulting in waste and pollution, endangering On-site safety and worker health and safety

Embodiment 1

[0020] Plenum pipes for oil and gas cutoff means removably interlocking way, see figure 1 , Including oil and gas pipelines 1, and the storage tank 14 collecting means 16, the set of oil and gas pipelines and hydrocarbon gas conduit end loading arm 1 is connected to the other end of the storage tank 16 penetrates into the interior, for delivering oil into the storage tank 16 collecting apparatus 14 communicates with the top of the storage tank 16, an upper portion 16 for collecting volatile oil storage tank, means for loading and unloading of oil and gas plenum duct linkage means further comprises a one-way cutoff ⅰ2 pipelines, gas pipelines Ⅱ 3, Passing cylinder 4, the connecting flange 5, I6 link mechanism, the link mechanism ⅱ7, the link mechanism ⅲ8, lower seal member 10, the sealing plug 11, the sealing member 12, gas interface 13, the feed cylinders 4 through the interface with the gas phase the position of the upper end 13 is fixed to the connecting flange 5, the lower end ...

Embodiment 2

[0025] In Example 1, except that, for the loading and unloading of oil and gas plenum duct linkage means further comprises a one-way cutoff 9 compensator, the compensator 9 is provided between the link mechanism Ⅰ6 Ⅱ7 link mechanism. 9 of the compensator spring compensator, the compensator spring having one end connected to the right end of the link mechanism Ⅱ7 the other end connected to the upper end of the link mechanism Ⅰ6, the cylinder stroke can be effectively prevented not uniform size storage tank port resulting not fixed damage to the link, to ensure that shut-off means (sealing member 12, the sealing plug 11, the lower seal member 10) with a locking mechanism (link mechanism) linkage opened. Set gas conduit for oil and gas handling the linkage means further comprises a one-way cutoff rubber seal 15, the sealing rubber 15 is provided with a connecting flange 5 at a storage tank 16 is connected. Can further improve the sealing interrupting mechanism. Upper seal 12, lower s...

Abstract

The invention discloses a gas collection pipeline linkage one-way cut-off device and method for oil gas loading and unloading. The device comprises an oil gas conveying pipeline, a first gas conveying pipe, a second gas conveying pipe, a material passing type air cylinder, a connecting flange, a first connecting rod mechanism, a second connecting rod mechanism, a third connecting rod mechanism, a lower sealing piece, a piston, an upper sealing piece, a gas phase connector, a collecting device, a sealing rubber and a storage tank. The oil gas conveying pipeline and the gas phase connector are fixed to the upper end of the connecting flange, linear sealing is adopted between the upper sealing piece and the lower sealing piece, the upper sealing piece and the gas phase connector are welded and fixed, the lower sealing piece and the third connecting rod mechanism are welded and fixed, the first connecting rod mechanism, the second connecting rod mechanism and the third connecting rod mechanism are connected through hinges, in addition, the third connecting rod mechanism is hinged to the oil conveying pipeline, and the collecting device is flexibly connected with the gas phase connector. The device is closed under the combined action of a linkage mechanism and oil gas pressure of the gas phase pipeline, oil gas is prevented from flowing back and leaking through a loading and unloading arm gas collecting pipeline, meanwhile, operation procedures are reduced, and labor intensity is lowered.

Description

Technical field [0001] The present invention relates to fluid handling equipment, particularly relates to a gas collector conduit for hydrocarbon linkage unidirectional truncation handling apparatus and method. Background technique [0002] Volatile oil and gas leakage during loading and unloading is difficult to overcome technical bottlenecks at home and abroad, on the one hand leakage losses caused by power shortage in some industries sector, to develop a negative impact on the national economy. Meanwhile, oil and gas leaks caused by environmental pollution, seriously endangering the health of workers, the shipment of oil and gas field full of media, explosion, poisoning and other accidents can easily occur, significant losses to the national economy. Thus research on efficient and high sealability current gas fluid loading arm is extremely urgent. [0003] In particular, the gas collecting duct that all handling arm (gas pipe) is connected to a vapor recovery system, when a ...
