Description
Technical field
The utility model relates to a kind of petroleum vapor recovery electronics gas liquid ratio modulating valve, belongs to fluid technical field of automatic control.
Background technique
Petroleum vapor recovery electronics gas liquid ratio modulating valve belongs to the core component of gas station's secondary oil gas reclaiming system, is a kind of modulating valve being obtained stepless output fluid by varying in size of input coil electric current.Petroleum vapor recovery electronics gas liquid ratio modulating valve is arranged between the inner gas circuit copper pipe that attracts from gas-oil separation joint of oilling machine and oil-gas recovery vacuum pump, and near oil-gas recovery vacuum pump Way in.
The gas liquid ratio modulating valve that current domestic gas station is using mainly is divided into two kinds of specifications: one relies on Mechanical course, by the aperture of the oil pressure change automatic regulating valve mouth in pipeline; Another kind relies on electrical proportional to control, and regulated the aperture of valve port by the size of current of control inputs coil.Front a kind of mechanically controlled type gas liquid ratio modulating valve, owing to relying on the aperture of the oil pressure change automatic regulating valve mouth in pipeline, cause proportional control precision low, stability is poor; Rear a kind of electrical proportional controls formula gas liquid ratio modulating valve, mainly exists without external adjusting screw at present, and the more difficult flow to output fluid carries out the defect that trace regulates.
Summary of the invention
The purpose of this utility model be to provide a kind of reasonable in design, compact structure, can stepless output fluid can carry out to the flow of output fluid the petroleum vapor recovery electronics gas liquid ratio modulating valve that trace regulates.
The utility model is a kind of petroleum vapor recovery electronics gas liquid ratio modulating valve, comprise valve body, be placed in static iron core assembly and the coil on valve body top, be placed in the dynamic core assembly of static iron core component internal, be placed in the balance spring between static iron core assembly and dynamic core assembly, the center of static iron core assembly is provided with adjusting screw and O shape circle B.
O shape circle A is provided with between described valve body and static iron core assembly.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure sectional view of the present utility model.
In figure: 1-valve body, 2-O shape circle A, 3-balance spring, 4-static iron core assembly, 5-adjusting screw, 6-waveform bullet pad, 7-nut, 8-O shape circle B, 9-coil, 10-moves core assembly, 11-valve port pad.
Embodiment
As shown in Figure 1, the utility model is primarily of valve body 1, be placed in static iron core assembly 4 and the coil 9 on valve body 1 top, be placed in the dynamic core assembly 10 of static iron core assembly 4 inside, the balance spring 3 be placed between static iron core assembly 4 and dynamic core assembly 10 is formed, the center of static iron core assembly 4 is provided with adjusting screw 5 and O shape circle B8, is provided with O shape circle A2, is connected and fixed between coil 9 and static iron core assembly 4 by waveform bullet pad 6 and nut 7 between valve body 1 and static iron core assembly 4.
During work, namely when oilling machine operator starts to put the gun refueling, oil-gas recovery vacuum pump is synchronously opened, the computer control panel of oilling machine reclaims ratio according to the gas-liquid of setting, synchronously certain electric current is inputted to coil 9, coil 9 is made to produce a corresponding magnetic force, this magnetic force compression balance spring 3, dynamic core assembly 10 starts to move upward, namely the valve port of valve body 1 is opened, under the effect of oil-gas recovery vacuum pump, the oil gas attracted from gas-oil separation joint along the direction of arrow shown in accompanying drawing 1 by exporting the valve port of valve body 1.Along with the increase of nozzle gasoline output quantity, the computer control panel of oilling machine reclaims ratio according to the gas-liquid of setting, the input current of coil 9 is also synchronously increased, the corresponding increase of the compression displacement of magnetic force to balance spring 3, the displacement that core assembly 10 is moved upward increases, thus the oil gas flow exported is also larger.Therefore the output oil gas flow of petroleum vapor recovery electronics gas liquid ratio modulating valve increases along with the electric current inputted coil 9 and increases, and namely achieves stepless output fluid.
Be provided with O shape circle A2 between valve body 1 and static iron core assembly 4, can anti-fluid leak from the gap location of valve body 1 and static iron core assembly 4.
The center of static iron core assembly 4 is provided with O shape circle B8, can anti-fluid leak from the gap location of static iron core assembly 4 and adjusting screw 5.
The center of static iron core assembly 4 is provided with adjusting screw 5, when because of the wearing and tearing of long-term work inner body, suction reduces oil-gas recovery vacuum pump, the oil gas output quantity of petroleum vapor recovery electronics gas liquid ratio modulating valve will reduce, now, by rotating up adjusting screw 5, reduce balance spring 3 to the impacting force of dynamic core assembly 10, thus increase the petroleum vapor recovery oil gas output quantity of electronics gas liquid ratio modulating valve, make the oil gas output quantity of petroleum vapor recovery electronics gas liquid ratio modulating valve control within designing requirement scope; Same, when replacing uses new oil-gas recovery vacuum pump, if the suction of oil-gas recovery vacuum pump is bigger than normal, now, by being rotated down adjusting screw 5, increase balance spring 3 to the impacting force of dynamic core assembly 10, thus reduce the petroleum vapor recovery oil gas output quantity of electronics gas liquid ratio modulating valve, the oil gas output quantity of petroleum vapor recovery electronics gas liquid ratio modulating valve is controlled within designing requirement scope.
When oilling machine be in do not work time, namely, under coil 9 no electric circuit state, under the effect of balance spring 3, the valve port pad 11 bottom dynamic core assembly 10 is sealed on the valve port of valve body 1, now petroleum vapor recovery electronics gas liquid ratio modulating valve is in closed condition, exports without flow.
The utility model reasonable in design, manufacture cost is lower, and proportional control precision is high, stable performance, and implementation result is obvious.
