Description
Technical field
The present invention relates to hydraulic package, relate in particular to a kind of single-acting plunger type hydraulic manual mechanism that is applicable to the single-acting valve with Self-resetting actuator.
Background technique
Traditional hydraulic manual mechanism adopts piston-type hydraulic cylinder, piston is equipped with hole seal ring, hydraulic cylinder port is equipped with piston rod seal ring, and the pressure oil of hydraulic hand-pump enters piston cavity by oil pipe and oil hydraulic cylinder head tube joint, action of hydraulic force in piston together with piston rod thrust output.The oil circuit of hydraulic hand-pump adds plug sealing after being punched by outside.The correlated parts quantity of piston type man-operated mechanism is more, and the processing request of the endoporus of oil hydraulic cylinder is higher.
Summary of the invention
For the above-mentioned defect of existing piston type man-operated mechanism, the applicant is through Improvement, a kind of single-acting plunger type hydraulic manual mechanism is provided, adopt oil hydraulic cylinder, hydraulic hand-pump and fuel tank integral structure, oil hydraulic cylinder adopts plunger type, the project organization without plug is taked in the processing of hydraulic pressure duct, the present invention is had simple in structure, the feature that volume is little.
Technological scheme of the present invention is as follows:
The invention provides a kind of single-acting plunger type hydraulic manual mechanism, comprise mutually nested hydraulic cylinder and plunger, the upper cover of described plunger has axle seal ring and spacer ring, and upper supporting ring and lower support ring are placed in the both sides of axle seal ring and spacer ring; Hydraulic cylinder is connected with upper supporting ring and forms plunger cavity between hydraulic cylinder and plunger, and the periphery of hydraulic cylinder is provided with fuel tank; Also comprise hand-hydraulic pump piston, described hand-hydraulic pump piston below is connected with oil sucting one-way valve, and oil sucting one-way valve is connected with fuel tank by switch valve bottom chamber and the first oilhole; Described hand-hydraulic pump piston below is connected with force feed one-way valve, and force feed one-way valve, by the second oilhole, is connected with plunger cavity through the logical oil groove of spacer ring and upper supporting ring; When described switch valve is opened, plunger cavity is through logical oil groove and the spacer ring of upper supporting ring,, and is connected with fuel tank through the first oilhole through switch valve bottom chamber by the second oilhole.
Its further technological scheme is:
The valve seat of described force feed one-way valve and hand-hydraulic pump barrel close contact.
Described the first oilhole and the second oilhole inwardly punch from switch valve bottom chamber.
Useful technique effect of the present invention is:
Hydraulic hand-pump of the present invention and oil hydraulic cylinder and fuel tank are integrated, and oil hydraulic cylinder adopts plunger type, are sealed by the axle seal ring that is placed in hydraulic cylinder port position, and supporting ring is placed in the both sides of axle seal ring and spacer ring, have improved the ability of cylinder plunger bearing radial force.The valve seat of the force feed one-way valve of hydraulic hand-pump is compressed by hand-hydraulic pump barrel, and the in-house duct of hydraulic manual is connected by internal punches, has avoided need adding the problems such as plug by outside punching.The present invention has simple in structure, and volume is little, lower-cost advantage.
Brief description of the drawings
Fig. 1 is sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention is installed on the single-acting valve actuator main shaft place with Self-resetting actuator.In the time that the actuator of valve cannot drive valve because of fault, manual drive hand-hydraulic pump piston 1 promotes, and opens oil sucting one-way valve 4, sucks fluid through switch valve bottom chamber 5 and the first inner oilhole 7 from fuel tank 16.When hand-hydraulic pump piston 1 presses down, pressure oil is opened force feed one-way valve 8, by the second oilhole 9 of inside, logical oil groove through spacer ring 13 and upper supporting ring 14 enters plunger cavity 17, promote plunger 10 to hydraulic cylinder port direction (downward in Fig. 1) motion, overcome the spring force that acts on valve actuator main shaft, drive valve open or close.Plunger 10 is sealed by the axle seal ring 12 that is placed in hydraulic cylinder port, and plunger 10 is very large with the gap permission of hydraulic cylinder 15 endoporus, and the endoporus processing request of hydraulic cylinder 15 is very low.Upper supporting ring 14 and lower support ring 11 are placed in the both sides of axle seal ring 12 and spacer ring 13, have improved the ability of cylinder plunger bearing radial force.
When valve need to reset, open switch valve 6, the spring force that acts on the pneumatic actuator main shaft of valve drives plunger 10 to oil hydraulic cylinder bottom direction (in Fig. 1 upwards) motion, oil in plunger cavity 17 is through logical oil groove and the spacer ring 13 of upper supporting ring 14, by the second oilhole 9 through switch valve bottom chamber 5, flow back to fuel tank 16 through the first oilhole 7, valve is returned to origin-location.
The valve seat 3 of force feed one-way valve is compressed by hand-hydraulic pump barrel 2, and compact structure has been avoided punching and need adding the problem of plug from outside.Oil through road the first oilhole 7 and the second oilhole 9 that hydraulic manual is in-house, all punch from the switch valve bottom chamber 5 of switch valve 6 bottoms, avoided need adding from outside punching the problem of plug.Hydraulic hand-pump is communicated with by inner oilhole the first oilhole 7 and the second oilhole 9 with plunger cavity 17 and fuel tank 16, saves the processing of the parts such as oil pipe and relevant interface.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive without departing from the basic idea of the present invention or associate, within all should thinking and being included in protection scope of the present invention.
