Embodiment Construction

[0018] Below in conjunction with accompanying drawing, structural principle and implementation mode of the present invention are set forth in detail:

[0019] Such as figure 1 In the oil and gas recovery self-styled refueling gun shown, an independent oil and gas recovery cavity 13 is integrated in the lower part of the oil channel cavity 15 of the gun body, which forms a complete return air channel by communicating with the oil and gas separation assembly 2 and the barrel assembly 12, and connects with the oil channel phase separation. The inside of the gun barrel 23 integrates an oil gas recovery passage 25, an air supply passage 28 and an oil output passage 27, such as figure 2 and image 3 As shown, these three passages are formed by one-time extrusion. The oil and gas recovery passage plug A21 and the oil and gas recovery passage plug B26 respectively seal the two ends of the oil and gas recovery passage. The small hole 24 enters the oil and gas recovery passage 25, a...

Abstract

The invention discloses a self-sealing oil gun in the oil gas recovery field. An oil gas recovery channel is integrated in the self-sealing oil gun. The self-sealing oil gun comprises an oil gun body, a gun barrel assembly, a non-pressure self-sealing assembly, a vacuum self-sealing assembly, a push rod assembly, an oil gas separating assembly and a wrench assembly. An oil gas recovery cavity is integrated in the lower portion of a gun body oil way channel cavity. As the gun barrel structure integrally formed by the oil gas recovery channel, a gas supply channel and an oil liquid output channel, and a special oil gas separating assembly structure are adopted, the low flow resistance and the high flow rate are achieved, the efficiency of recovering oil gas when the oil gun works is improved, and the probability of oil-gas leakage is reduced. By the application of a novel non-pressure self-sealing and gun-jumping mechanism, the safety reliability and the stability of oil gun work are improved, atmosphere pollution is further reduced, and the self-sealing oil gun plays an important role in saving resources.

Description

technical field [0001] The invention relates to a self-styled refueling gun which is used in the field of oil and gas recovery and has an internal oil and gas recovery passage. Background technique [0002] At present, the oil and gas recovery technology has become more and more mature, but the oil and gas recovery self-sealing refueling gun, which is the terminal product of oil and gas recovery, generally has the disadvantages of complex assembly and processing technology, large weight, high flow resistance, and low reliability. Ordinary oil and gas recovery refueling guns generally realize the oil and gas recovery function by setting an oil and gas recovery cavity in the main channel of the gun body to cooperate with the plastic gas return pipe in the barrel or directly external oil and gas recovery channels. The main valve and the jumper mechanism are arranged in a V shape. Due to the limitations of the design structure, it becomes very difficult and expensive to try to r...
