Description
Technical field
This utility model relates to a kind of petroleum vapor recovery mechanical proportional valve, belongs to fluid technical field of automatic control.
Background technology
The petroleum vapor recovery core component of mechanical proportional Fa Shu gas station secondary oil gas reclaiming system, is a kind of adjustment valve that can accurately be exported 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 fuel charger, oil outlet end valve body is connected with the oil delivery hose of fuel charger.
Current domestic gas station, at the mechanical proportional valve used, substantially all dependence on import, is mainly the famous foreign brands such as OPW, VEEDER-ROOT, there is the defects such as import price is expensive, procurement cycle length, after-sale service response time are slow.
Utility model content
The purpose of this utility model is in that to provide a kind of reasonable in design, compact conformation, can accurately export the petroleum vapor recovery mechanical proportional valve of fluid, is mainly used in substituting the famous foreign brands such as OPW, VEEDER-ROOT.
This utility model is a kind of petroleum vapor recovery mechanical proportional valve, including oil inlet end valve body, it is placed in the O A of oil inlet end valve end, O B and O C, oil inlet end valve body is connected with oil outlet end valve body, the junction of oil inlet end valve body and oil outlet end valve body is provided with O F, slide assemblies, spring and gas circuit valve rod assembly it is provided with in oil outlet end valve body, oil inlet end valve body is provided with big flow adjustment screw and low discharge regulates screw, being provided with O D between big flow adjustment screw and oil inlet end valve body, low discharge regulates and is provided with O E between screw and oil inlet end valve body.
It is connected fixing between described gas circuit valve rod assembly and oil outlet end valve body by hole back-up ring.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure sectional view of the present utility model.
In figure: 1-O shape circle A, 2-O shape circle B, 3-oil inlet end valve body, the 4-O shape big flow adjustment screw of circle C, 5-, 6-O shape circle D, 7-low discharge regulates screw, 8-O shape circle E, 9-O shape circle F, 10-slide assemblies, 11-oil outlet end valve body, 12-hole back-up ring, 13-gas circuit valve rod assembly, 14-spring.
Detailed description of the invention
This utility model is mainly by oil inlet end valve body 3, it is placed in the O A1 of oil inlet end valve body 3 end, O B2 and O C4, oil inlet end valve body 3 is connected with oil outlet end valve body 11, the junction of oil inlet end valve body 3 and oil outlet end valve body 11 is provided with O F9, slide assemblies 10 it 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 big flow adjustment screw 5 and low discharge regulates screw 7, it is provided with O D6 between big flow adjustment screw 5 and oil inlet end valve body 3, low discharge regulates and is provided with O E8 between screw 7 and oil inlet end valve body 3, it is connected fixing between gas circuit valve rod assembly 13 with oil outlet end valve body 11 by hole back-up ring 12.
During work, namely when fuel charger operator starts to put the gun refueling, gasoline pump and oil-gas recovery vacuum pump synchronize to open, under the effect of gasoline pump, gasoline is by the direction of arrow shown in the drawings flowing, promote slide assemblies 10, make slide assemblies 10 compress spring 14 and produce relative displacement, so that the gas circuit valve port of oil inlet end valve body 3 is in opening; Simultaneously under the effect of oil-gas recovery vacuum pump, the oil gas produced when being refueled to motor vehicles by oil gun sucks back to oil storage tank along the direction of arrow shown in the drawings. When volume read-out one timing, can first pass through and big flow adjustment screw 5 is tentatively regulated, finely tune again through low discharge is regulated screw 7, carry out the flow of Precise Control of Oil gas, thus the oil gas produced when being refueled to motor vehicles by oil gun is by the oil gas of environmental requirement: volume read-out=(1��1.2): 1 reclaims.
It is provided with O D6 between big flow adjustment screw 5 and oil inlet end valve body 3, when rotating big flow adjustment screw 5, can prevent oil gas from leaking from the fit clearance of big flow adjustment screw 5 with oil inlet end valve body 3; Low discharge regulates and is provided with O E8 between screw 7 and oil inlet end valve body 3, when rotating low discharge and regulating screw 7, can prevent oil gas from leaking from the fit clearance of low discharge adjustment screw 7 with oil inlet end valve body 3.
It is connected by hole back-up ring 12 fixing between gas circuit valve rod assembly 13 with oil outlet end valve body 11, compares with the damascene structures of import like product, not only reduce assembly cost, and improve the efficiency of assembling of product.
When fuel charger is in and does not work, namely when gasoline pump and oil-gas recovery vacuum pump do not work simultaneously, under action from the spring 14, slide assemblies 10 returns to initial position, so that the gas circuit valve port of oil inlet end valve body 3 is closed, now the petroleum vapor recovery inside of mechanical proportional valve produces without flow.
This utility model simple in construction, manufacturing cost is relatively low, and flow control accuracy is high, and stable performance, implementation result is obvious.
