Abstract
The invention relates to a residual oil recovery device for a port loading arm. The recovery device comprises a double-piston hydraulic cylinder, a two-position three-way hydraulic operated directional valve, two ejector rod type one-way valves and a group of suction and discharge one-way valves, wherein the two-position three-way hydraulic operated directional valve is mounted on the double-piston hydraulic cylinder. Automatic reciprocating movement of piston rods of the double-piston hydraulic cylinder is controlled by the two-position three-way hydraulic operated directional valve and the two ejector rod type one-way valves, and oil is sucked and discharged by the aid of the suction and discharge one-way valves. The device can realize residual oil recovery required by the port loading arm.
Description
Technical field
The present invention relates to harbour oil transfer arm and remain oil product regenerative apparatus, be specially reclaim residual oil product in harbour oil transfer arm outer arm device.
Background technology
Harbour oil transfer arm a kind of connects oil carrier and oil pipe on the bank, completes the specialized equipment of oil product conveying.For ensureing security requirement, must to empty in oil transfer arm pipeline residual a large amount of oil products after oil transportation operation completes, the oil product in inner arm is recovered in pipeline on the bank or low level oil tank by gravity flow mode; Oil product in outer arm has to gratuitously be drained in charge of oil boats and ships because never having corresponding regenerative apparatus, causes a large amount of economic losses of port oil company.
Summary of the invention
The object of the present invention is to provide a kind of residual oil product regenerative apparatus on the oil transfer arm of harbour, the piston rod of the piston hydraulic cylinder that this device is arranged moves downward, and automatic reciprocating motion, realize the automatic recovery of residual oil product.
Technical scheme of the present invention:
A kind of residual oil product regenerative apparatus on the oil transfer arm of harbour, described device comprises liquid sucting valve, tapping valve, imbibition hydraulic fluid port check valve, post rod type check valve, piston hydraulic cylinder and two-position three way pilot operated directional control valve composition, liquid sucting valve, tapping valve, imbibition hydraulic fluid port check valve, post rod type check valve and two-position three way pilot operated directional control valve are arranged in the lumen pore that piston hydraulic cylinder is offered, and are undertaken fastening by screw thread.
Described a kind of residual oil product regenerative apparatus on the oil transfer arm of harbour, described residual oil product regenerative apparatus is installed on oil transfer arm equipment.
Beneficial effect of the present invention:
1, the present invention is without the need to electric control reversing, self realizes automatic reciprocating motion by residual oil product regenerative apparatus, reaches the object that oil residues product suck and get rid of, efficiently solves oil transfer arm and remain the irretrievable problem of oil product.
2, the present invention effectively reduces the economic loss of port oil company.
3, the present invention effectively improves the automatization level of harbour oil transfer arm oil transportation operation.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1 and Figure 2, the present invention includes liquid sucting valve 1, tapping valve 2, imbibition hydraulic fluid port check valve 3, post rod type check valve 5, piston hydraulic cylinder 4 and two-position three way pilot operated directional control valve 6 to form, liquid sucting valve 1, tapping valve 2, imbibition hydraulic fluid port check valve 3, post rod type check valve 5 and two-position three way pilot operated directional control valve 6 are arranged in the lumen pore that piston hydraulic cylinder 4 is offered, and are undertaken fastening by screw thread.
As shown in Figure 3, hydraulic principle of the present invention and working process as follows:
In figure, P line represents the feed liquor hydraulic fluid port of this device; What O line represented this device returns liquid hydraulic fluid port, the discharge opeing hydraulic fluid port that X1 line represents the imbibition hydraulic fluid port of residual oil product, X2 line represents residual oil product.Pressure oil directly enters the oil suction chamber of two-position three way pilot operated directional control valve from P mouth, a road pressure oil enters the back cavity of post rod type check valve simultaneously, another road enters the rod chamber of piston hydraulic cylinder power end 5-2, the piston rod 5-3 of piston hydraulic cylinder is driven to move downward, the oil return of piston hydraulic cylinder power end 5-2 rodless cavity is through two-position three way pilot operated directional control valve and O line, direct oil sump tank, residual oil product now in oil transfer arm is drawn in piston hydraulic cylinder liquid sucking-discharging end 5-1 rodless cavity through imbibition hydraulic fluid port check valve 3 from X1 line, the residual oil product be stored in piston hydraulic cylinder liquid sucking-discharging end 5-1 rod chamber is discharged through X2 line.When piston rod 5-3 moves downward and backs down the spool of push rod check valve, the pressure oil entering post rod type check valve back cavity enters into the back cavity of post rod type check valve by push rod check valve, and enter into the control oil pocket of two-position three way pilot operated directional control valve, overcome the spring force of two-position three way pilot operated directional control valve, two-position three way pilot operated directional control valve is commutated, the pressure oil entering two-position three way pilot operated directional control valve oil suction chamber enters piston hydraulic cylinder power end 5-2 rodless cavity through two-position three way pilot operated directional control valve, drive the piston rod 5-3 upward movement of piston hydraulic cylinder, the oil return of piston hydraulic cylinder power end 5-2 rod chamber enters piston hydraulic cylinder power end 5-2 rodless cavity through two-position three way pilot operated directional control valve, realize differential oil line, the residual oil product be now drawn in piston hydraulic cylinder liquid sucking-discharging end 5-1 rodless cavity is discharged in rod chamber from rodless cavity through tapping valve.When piston rod 5-3 upward movement and when backing down the spool of push rod check valve, the pressure oil entering two-position three way pilot operated directional control valve control oil pocket is connected back to fuel tank through post rod type check valve mutually with O line, two-position three way pilot operated directional control valve resets, the pressure oil of piston hydraulic cylinder power end 5-2 rodless cavity is connected with O line again, and residual oil product regenerative apparatus completes a liquid sucking-discharging process.Pressure oil enters piston hydraulic cylinder power end 5-2 rod chamber again simultaneously, drives the piston rod 5-3 of piston hydraulic cylinder to move downward, automatic reciprocating motion like this, realizes the automatic recovery of residual oil product.
Fig. 4 is erecting equipment and the position that harbour oil transfer arm remains oil product regenerative apparatus: 1, residual oil product regenerative apparatus 2, harbour oil transfer arm.
