Description
Technical field
The present invention relates to the vehicular oil air separation, specifically a kind of exhaust hydrant cart thorough, that improve oil-gas separation efficiency and reduction use cost vacuumizes gas and oil separating plant.
Background technology
The typical, filtered separator of prior art mainly is comprised of housing, separation filter core, Coalescence filter core, crosspointer differential manometer, automatic blow off valve valve air relief, Manual air-release valves, automatic drain valve and Manual water drain valve etc.
Separating filter core and be the second level water-oil separating element in the separator, is to spray the strong polytetrafluoroethylene (PTFE) of repellency on the stainless steel steel wire of 100 orders/in to make with mesh.It is fixed on the cruciform joint of outlet lower end by center bolt.
Coalescence filter core is first order water-oil separating element, also is the main element of water-oil separating.It is comprised of the diameter hydrophilic fibers layer different with density.Its inner frame is the cylinder that aluminium expanded sheets is made; The outer outer casing play of filter course is that the rustproof aluminium sheet with punching rolls and forms.It is fixed on the dividing plate in the entrance point shell cover with screw rod and support thereof.
Gs-oil separator is set directly at the case top of above-mentioned filter separator, specifically with the automatic blow off valve valve air relief upside-down mounting under the top cover of top gas receiver, when in the housing gas being arranged, gas is assembled at the gas receiver top, its pasta is descended, force stainless steel ball to descend, and the decline of the valve disc on the drivening rod, vent valve automatically opened.After gas was emitted, pasta rose in the gas receiver, forced stainless steel ball to rise, and the rising of the valve disc on the drivening rod, leaned on the buoyancy of ball float to make valve disc and seal washer sealing, vent valve autoshutdown.Manual air-release valves also is housed on the gas receiver top cover.Manual air-release valves must be at first opened during work, just the automatic blow off valve valve air relief automatic deflation can be made.When gas in the pipeline separates when complete, automatically block pipeline.
In the pump oil pipe line, the filter separator with gs-oil separator of prior art is mounted on the vacuum-pumping pipeline between auxiliary oil pump and the main oil pump, realizes the gas in the main oil pump is pumped by gs-oil separator.Auxiliary oil pump is less with the vacuum-pumping pipeline bore that the main oil pump outlet links to each other, length is shorter, in the vacuum, fluid flow velocity in this pipeline is very fast, as blocking too early vacuum-pumping pipeline, then also there is too much gas in the main oil pump, can't drop into normal operation, otherwise as can not in time block vacuum-pumping pipeline, fluid will enter gas extraction system through auxiliary oil pump, thus, and the work that will inevitably bring a large amount of corresponding oil-collectings and reclaim oil plant.During above-mentioned gs-oil separator work, when the interface of oil and gas rises when ball float being floated close main valve, may exist because of a large amount of gas mixtures and enter gs-oil separator, make the very fuzzy situation of the interface of oil and gas in the gs-oil separator, so, the induction of the Direct Action Type of ball float may exist mistake to block the path of bleeding, or frequently fluctuates and cause the wild effect of bleeding; The support staff directly opens and closes Manual air-release valves according to practical experience, can't finish effectively accurately and timely and vacuumize operation, causes the problems referred to above, so that the work workman input cost of a large amount of corresponding oil-collecting and recovery oil plant is higher, use cost is just higher.
In sum, the gs-oil separator exhaust of prior art is not thoroughly, oil-gas separation efficiency is low and use cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of exhaust hydrant cart thorough, that improve oil-gas separation efficiency and reduction use cost and vacuumize gas and oil separating plant.
For realizing that the technical scheme that above-mentioned purpose of the present invention adopts is: a kind of hydrant cart vacuumizes gas and oil separating plant, comprise housing, be arranged on housing bottom be used for vacuum-pumping pipeline on the oil gas admission passage connected of main oil pump, be arranged on case top be used for vacuum-pumping pipeline on the exhaust passage connected of auxiliary oil pump, described oil gas admission passage and exhaust passage all are communicated with the inner chamber of housing, are provided with ball float in the inner chamber of housing; It is characterized in that: the top of described ball float is fixed with air bleeding valve, and this air bleeding valve comprises again main valve and pilot valve;
The valve body bottom of described main valve is fixed on the top of ball float, the spool at this valve body top and the valve port of case top coupling, described exhaust passage is fixed on the housing at valve port place, ball float is fluctuated be with movable valve plug to open and close valve port, and the realization exhaust passage is communicated with the inner chamber of housing or closes;
The balance valve core of described pilot valve is fixed in the inner chamber of valve body, pilot valve piston be fixed on the spool top, piston jacket is provided with dividing plate, dividing plate is fixed on the valve port place, make and form the anti-chamber that pushes away between piston and the dividing plate, this anti-chamber that pushes away is communicated with the exhaust passage by inlet channel, and this inlet channel opens and closes by the piston control that moves up and down with the main valve one, and described balance valve core is communicated with the anti-chamber that pushes away.
When said structure uses, main oil pump is installed on the oil gas admission passage on the vacuum-pumping pipeline, auxiliary oil pump is installed on the exhaust passage on the vacuum-pumping pipeline; When auxiliary oil pump is started working, oil-gas mixture in the vacuum-pumping pipeline enters in the inner chamber of housing through the oil gas admission passage, the spool of the main valve of air bleeding valve and balance valve core are opened Exhaust Gas under the ball float action of gravitation, when main oil pump sucks gas in the vacuum-pumping pipeline seldom the time, carry liquid also to enter in the inner chamber of housing thereupon, gas-liquid is separated in the inner chamber of housing, and gas is discharged; When large quantity of fluid after the emptying of main oil pump suction line was drawn in the inner chamber of housing, ball float was risen by buoyancy and closes air bleeding valve, at this moment just can close auxiliary oil pump, started main oil pump and carried normally operation; In this Oil-gas Separation process, ball float is small fluctuates by the inner pilot valve induction of installing of main valve, when ball float has very little downward action situation, the piston of pilot valve moves down with the ball float one and opens inlet channel, gas enters the anti-chamber that pushes away on pilot valve top, also namely enter piston top, and the pressure-bearing surface of piston is larger than the spool of main valve, then main valve is in this pressure differential situation, again open the continuation exhaust, by the gas that the very little space of topmost in the inner chamber of pilot valve induction housing exists, form the unlatching sensitivity that the further participation of propulsive thrust improves air bleeding valve to the control of main valve.
Because said structure, pilot valve of the present invention has improved the unlatching sensitivity of air bleeding valve, both satisfied the unimpeded exhaust in the atm number situation, the exhaust that has also solved the little tolerance of later stage of bleeding is thorough, improved the efficient of Oil-gas Separation, also just reduce the artificial input that artificially collects fluid, reduced use cost.
