Description

M258982 3. Creation Instructions (1) [Technical Field of New Type] This creation is about a gas refueling oil and gas recovery warning, especially a gas reclaiming oil and gas recovery warning [previous technology] ° For a long time, due to the refueling of gas stations vehicles The leaks and leaks from time to time often cause pollution of the air, causing employees and nearby residents to be greatly affected because of long-term exposure to $, inferior: Kang. It is understood that more than 30,000 volatile organic pollutants are released in Taiwan: equipment, which is estimated to reduce about 22,000 ㈣: H, can reduce about 73% of volatile organic pollutants < Second, the composition will be in the sun Under the catalysis, the degree of deterioration of the milk with nitrogen oxides has been increasing year by year, and it has also caused the government to promote the recovery of oil and gas. Government / compulsory gas station operators must improve within a specified period of time. The stern line on the second side of the fuel tank is recycled to the underground oil storage tank to improve the seriousness caused by the volatile organic compounds in the air. There is a "design to solve the disadvantages of the traditional use of fuel refueling. But different designs, but These different structures are set in / in the shortcomings. Similar to the previous patents, refueling and robbing the Republic of China's new patent announcement No. 4 5 4 7 1 9 The structure of the fuel injection pipe fittings at the J plus station is a structure composed of s pieces The improvement is mainly in the environment of people who receive the sound generation device of the induction device of the gas dispenser and produce the volatility of oil and gas into the gas station. Oil tank unloading pollution (in recent years, the NOx response in the oil and gas has become a global threat, policy, or directly formed oil and gas recovery structure of oil and gas, through or to reduce the impact of gas station perimeter. In the structure design, such as Lizhong, it is disclosed that a fuel station

M258982 IV. Creation instructions (2) Pipes, motors, and refueling guns and other components; It is characterized in that two closed spaces are provided from the beginning to the end of the power nozzle, one of which comes out from the center of the front-end coaxial nozzle to form -Oil channel. The other side of the outer edge of the coaxial nozzle from the front end = out = open y into the oil and gas channel ‘the front end of the oil and gas channel is opened with a cover’ to facilitate the collection of oil and gas. Eight w ίI 'Γ: A thin oil and gas recovery tube is set inside the tube, with main ends at both ends, and a -locating ring is provided below it, the positioning: == out claws, each claw A step is formed below. Make the outer end of the inner tube two! At the same time, when the stepped edge can just meet the end of the handle of the oil recovery, the outer end of the outer edge and the cylindrical end of the two can be inserted into the oil and gas channel, and the tubing The inner edge of the outer g is gasoline, and the six is taken from the coaxial nozzle, the main, and the Γ ^. After the oil body channel is grabbed by the refueling, the fuel tank port 4, and the second two: make, while refueling to grab the outer cover It is matched with the channel, and the oil and gas recovery is rolled by the pumping of the motor, so that the oil and gas can be discharged through the oil and gas. After reaching the motor, it flows back to the body for filtration and recovery of the oil body. Effect. , Disclosed-the Republic of China's new patent publication No. 2 0644 patent set, which is a dry pump, oil and gas recovery device for volatile liquid distribution device driven pump, _ + pipes for liquid use, an oil A gun, a motor pressure motor, a liquid-driven pump, a conduit for oil and gas, and an oil end; the outlet / flow meter. The duct is installed in the liquid duct for free gas guidance, and its fruit 'supplies liquid to the liquid duct; the position for oil and gas supply; the ^: the free end is located at the free end where the oil can be collected. Pressure motor, arranged in the motor-driven pump and the oil grab

M258982 IV. Creation instructions (3) On the path of the liquid conduit, and the liquid flow meter, which is connected to the oil grab; The hydraulic motor has a sealed housing, and the housing contains a pair of intermeshing rollers. The liquid flowing through the hydraulic motor rotates the pair of rollers. The air pump is installed on the oil and gas pipeline and contains a sealed shell. The shell contains a pair of rollers that are spit to each other. The roller of the hydraulic motor has the same size and shape as the roller of the pneumatic pump; the hydraulic motor drives the pneumatic pump through multiple gears. There is a connection between the casing of the hydraulic motor and the casing of the air pump. The connection includes a small diameter hole provided upstream of the roller of the air pump so that the liquid supplied through the hydraulic motor can be forced to leak out gradually. Into the air pump. [New content] In the conventional oil and gas recovery device for the technical problem to be solved in this creation, the method of oil and gas recovery adopts the method of recovering oil and gas through the oil and gas channel and the oil and gas recovery pipe, so the conventional oil and gas recovery device can only be pure The oil and gas recovery is performed in the field, but the user of the oil gun cannot easily know immediately that the oil and gas is being recovered correctly, especially those without any sensing components for oil and gas recovery. Therefore, if a refueling oil and gas recovery device can be designed for the lack of the conventional oil and gas recovery device, and in particular, an oil and gas recovery warning sound generating device is provided, so that a user of the oil gun can perform oil and gas recovery every time, As long as the audible and recognizable sound from the oil and gas recovery warning sound generating device is heard, it can be easily determined that the oil and gas is being recovered, and this creation should have great practicality.

Page 7 M258982 Creation Instructions (4) The technical means for solving the problem in this creation The technical means used are the sound-generating components of the oil and gas recovery warning sound production, which can be heard and recognized. The warning sound generating device, the main body, the ring-shaped main member, and then a screw. The sound-generating component gas is being recovered. If at the time of refueling, the oil and gas returned by the refueling is created to solve at least one problem of the conventional technology, the extended threaded section of the ring body is used to form at least one bio-device, and then the refilling effect is generated by the warning sound of oil and gas recovery. A grab user can simply judge by sound, that is, can correctly determine whether oil and gas are being returned. ^ = The extended thread section of the designed oil and gas recovery body is formed by at least one closure cap screwed onto the extension of the annular body. '二 j ^ ^ Through film composition. When the oil is grabbed, the sound-generating component emits an audible sound. The energy-generating component has no effect; W This creation contrasts with the oil and gas of the previous technology; in order to make use of the derogation effect of this creation, when gr7 is installed, users can simply judge θ based on the auditory UB effect. ^ Know this creation 杳Moreover, whether the right-handed oil-breaking mill is correctly recovered, Putian has great practicability. And the achievements: 1 ί techniques and means adopted to achieve the intended purpose more ^ ^ 1 Your detailed description and drawings about this creation, I believe that the purpose, characteristics and features of this creation can be obtained in-depth and Specific M258982
