The oil-gas recovery mechanical proportional valve is mainly composed of an oil inlet end valve body (3), an oil outlet end valve body (11), a slide assembly (10), a spring (14), a gas way valve rod assembly (13), a large-flow adjusting screw (5), a small-flow adjusting screw (7) and the like. According to the oil-gas recovery mechanical proportional valve, precise output fluid can be obtained by rotating the large-flow adjusting screw (5) and the small-flow adjusting screw (7); the oil-gas recovery mechanical proportional valve is simple in structure, low in manufacturing cost, high in flow control precision, stable in performance and remarkable in implementation effect.
Description
Technical field
The present invention relates to a kind of petroleum vapor recovery mechanical proportional valve, belong to fluid technical field of automatic control.
Background technique
The petroleum vapor recovery core component of mechanical proportional Fa Shu gas station secondary oil gas reclaiming system is a kind of modulating valve that can obtain accurate output fluid by rotating large and small flow screw.The oil inlet end valve body of petroleum vapor recovery mechanical proportional valve is connected with the gas-oil separation joint of oilling machine, oil outlet end valve body is connected with the oil delivery hose of oilling machine.
The mechanical proportional valve that current domestic gas station is using, basic all dependence on import, are mainly the famous foreign brands such as OPW, VEEDER-ROOT, there is the defects such as import price is expensive, procurement cycle long, the after sales service response time is slow.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in design, compact structure, can the petroleum vapor recovery mechanical proportional valve of accurate output fluid, be mainly used in the famous foreign brands such as alternative OPW, VEEDER-ROOT.
The present invention is a kind of petroleum vapor recovery mechanical proportional valve, comprise oil inlet end valve body, be placed in O shape circle A, O shape circle B and O shape circle C of oil inlet end valve end, oil inlet end valve body is connected with oil outlet end valve body, the joint of oil inlet end valve body and oil outlet end valve body is provided with O shape and encloses F, sliding assembly, spring and gas circuit valve rod assembly is provided with in oil outlet end valve body, oil inlet end valve body is provided with large discharge adjusting screw and small flow adjusting screw, be provided with O shape between large discharge adjusting screw and oil inlet end valve body and enclose D, be provided with O shape between small flow adjusting screw and oil inlet end valve body and enclose E.
Between described gas circuit valve rod assembly and oil outlet end valve body, passing hole back-up ring is connected and fixed.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure sectional view of the present invention.
In figure: 1-O shape circle A, 2-O shape circle B, 3-oil inlet end valve body, 4-O shape circle C, 5-large discharge adjusting screw, 6-O shape circle D, 7-small flow adjusting screw, 8-O shape circle E, 9-O shape circle F, 10-sliding assembly, 11-oil outlet end valve body, 12-hole back-up ring, 13-gas circuit valve rod assembly, 14-spring.
Embodiment
The present invention is primarily of oil inlet end valve body 3, be placed in the O shape circle A1 of oil inlet end valve body 3 end, O shape circle B2 and O shape circle C4, oil inlet end valve body 3 is connected with oil outlet end valve body 11, oil inlet end valve body 3 is provided with O shape with the joint of oil outlet end valve body 11 and encloses F9, sliding assembly 10 is provided with in oil outlet end valve body 11, spring 14 and gas circuit valve rod assembly 13, oil inlet end valve body 3 is provided with large discharge adjusting screw 5 and small flow adjusting screw 7, be provided with O shape between large discharge adjusting screw 5 and oil inlet end valve body 3 and enclose D6, be provided with O shape between small flow adjustment spiral shell 7 and oil inlet end valve body 3 and enclose E8, between gas circuit valve rod assembly 13 and oil outlet end valve body 11, passing hole back-up ring 12 is connected and fixed.
During work, namely when oilling machine operator starts to put the gun refueling, gasoline pump and oil-gas recovery vacuum pump are synchronously opened, under the effect of gasoline pump, gasoline is by direction of arrow flowing shown in the drawings, promote sliding assembly 10, make sliding assembly 10 Compress Spring 14 produce relative displacement, thus make the gas circuit valve port of oil inlet end valve body 3 be in opening state; Simultaneously under the effect of oil-gas recovery vacuum pump, the oil gas produced when being refueled to Motor Vehicle by oil gun sucks back in oil storage tank along the direction of arrow shown in the drawings.When volume read-out one timing, can first by tentatively regulating large discharge adjusting screw 5, again by finely tuning small flow adjusting screw 7, carry out the flow of Precise Control of Oil gas, thus the oil gas produced when being refueled to Motor Vehicle by oil gun is by the oil gas of environmental requirement: volume read-out=(1 ~ 1.2): 1 reclaims.
Being provided with O shape between large discharge adjusting screw 5 and oil inlet end valve body 3 and enclosing D6, when rotating large discharge adjusting screw 5, can prevent oil gas from leaking from the matching gap of large discharge adjusting screw 5 and oil inlet end valve body 3; Being provided with O shape between small flow adjusting screw 7 and oil inlet end valve body 3 and enclosing E8, when rotating small flow adjusting screw 7, can prevent oil gas from leaking from the matching gap of small flow adjusting screw 7 and oil inlet end valve body 3.
Between gas circuit valve rod assembly 13 and oil outlet end valve body 11, passing hole back-up ring 12 is connected and fixed, and compares, not only reduce assembly cost with the damascene structures of import like product, and improves the efficiency of assembling of product.
When oilling machine be in do not work time, namely when gasoline pump and oil-gas recovery vacuum pump do not work simultaneously, under action from the spring 14, sliding assembly 10 gets back to initial position, thus make the gas circuit valve port of oil inlet end valve body 3 be in closed condition, now the inside of petroleum vapor recovery mechanical proportional valve produces without flow.
Structure of the present invention is simple, and manufacture cost is lower, and flow control accuracy is high, stable performance, and implementation result is obvious.
