Hose reel device with volatile gas recovery function

Abstract

The invention relates to a rubber hose reel device. The rubber hose reel device comprises a rubber hose, a reel, a coil spring, a ratchet wheel limiting mechanism and a valve body; the rubber hose is wound on the reel, and the liquid outlet end of the rubber hose is connected with an oil gun; the valve body comprises a valve seat and a valve core, and the valve core is provided with a liquid inlet; and the rubber hose is a coaxial double-layer rubber hose comprising a core cavity and an interlayer cavity, the core cavity is a gas path, and the interlayer cavity is a liquid path. The rubber hose reel device further comprises a liquid-gas separator; the valve seat, the valve core and the liquid-gas separator are each internally provided with a gas path and a liquid path; the inner ends of the gas path and the liquid path which are arranged in the valve seat and the inner ends of the gas path and the liquid path which are arranged in the valve core communicate correspondingly; the outer end of the gas path arranged in the valve seat communicates with a gas path arranged in an oil-gas separator through a pneumatic hose; the outer end of the liquid path arranged in the valve seat communicates with the liquid path arranged in the liquid-gas separator through a hard bent pipe; the core cavity and the interlayer cavity of the rubber hose communicate with the gas path and the liquid path which are arranged in the liquid-gas separator correspondingly; and the outer port of the gas path arranged in the valve core communicates with an external negative pressure source. The rubber hose reel device has an oil-gas separation function, so that the energy saving and environment friendly effects are achieved, and national development requirements are met.

Description

technical field [0001] The invention belongs to the technical field of fluid conveying equipment, in particular to a rubber hose reel device with the function of recovering volatile gas. Background technique [0002] The hose reel device is generally used for fluid transportation including fuel oil, and is usually equipped with a coil spring and a ratchet limit device; under the action of the coil spring, the reel has a pre-tightening force opposite to the direction of the hose; the hose pulls When it is pulled out to a certain position, the ratchet will snap into the tooth groove of the ratchet, the limit device will act, the reel will be stuck, the rubber hose will no longer be affected by the reel recovery pre-tightening force, and the rubber hose can be refilled within the radius of the pulled out length. The fluid material to be transported; after filling, continue to pull the rubber hose outward, the pawl moves to the vacant position of the ratchet wheel, releases the ...

Problems solved by technology

[0003] As the country pays more and more attention to environmental protection issues, it is required that gas stations must be equipped with oil and gas recovery systems. Although the existing rubber hose reel device can meet the business needs of gas stations, it cannot play the role of oil and gas separation, and cannot meet relevant regulations and technical specifications. requirements
