Abstract
The utility model discloses a kind of hydraulic oil drain device, comprise housing, described case inside is provided with top connection; On the downside of described top connection, piston is installed; Also hydraulic liftout apparatus is installed below described piston; The housing wall ejecting end top of described hydraulic liftout apparatus is embedded with hollow pin; Described case inside tail end is provided with lower contact; Described hydraulic liftout apparatus is U-tube; Hydraulic oil is marked with in described U-tube; Described U-tube one end is provided with seben, and the other end is provided with pad; Described seben and hollow pin are fitted, and described pad and piston are fitted.Hydraulic oil drain device of the present utility model, structure is simple, and stability is strong; Due to U-tube near hollow pin one end than more than the long twice in close piston one end, so hydraulic pressure dynamics is larger, can disposablely directly hollow pin be cut off; Shear more convenient, and be not easy to damage.
Description
Technical field
The utility model relates to a kind of hydraulic oil drain device, belongs to oil exploration equipment accessory technical field.
Background technology
Bleeder is connected at the bottom of rear lower going-into-well with oil well pump, oil pipe, screen casing, oil pipe, dead blocking up, and releases the sump oil sewage on pump and in oil pipe, prevented from taking sump oil sewage to ground during oil pipe by bleeder in well, reduce environment pollution, easy to operate, safety, long service life, lets out dirty effective; In bar oil pumping system, bleeder is that in whole system, cost is minimum, is also the weakest link, has the oil pumping system of 20% to lose efficacy all according to statistics because bleeder damage causes; What current use was maximum is eccentric type striking oil draining apparatus; And the reliability of eccentric type striking oil draining apparatus is determined by the structure of itself and sealing means; Main failure mode has: cut groove corrosion failure, sealing mat or sealing ring ageing failure, thread looseness cause seal failure.
Utility model content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of hydraulic oil drain device, its shearing is more convenient, and is not easy to damage.
(2) technical scheme
Hydraulic oil drain device of the present utility model, comprises housing, and described case inside is provided with top connection; On the downside of described top connection, piston is installed; Also hydraulic liftout apparatus is installed below described piston; The housing wall ejecting end top of described hydraulic liftout apparatus is embedded with hollow pin; Described case inside tail end is provided with lower contact; Described hydraulic liftout apparatus is U-tube; Hydraulic oil is marked with in described U-tube; Described U-tube one end is provided with seben, and the other end is provided with pad; Described seben and hollow pin are fitted, and described pad and piston are fitted.
Further, described hollow pin and housing installation place are provided with O type circle.
Further, on the upside of described hollow pin, inner face is provided with two sealing limited blocks.
Further, described U-tube near hollow pin one end than more than the long twice in close piston one end.
(3) beneficial effect
Hydraulic oil drain device of the present utility model, structure is simple, and stability is strong; Due to U-tube near hollow pin one end than more than the long twice in close piston one end, so hydraulic pressure dynamics is larger, can disposablely directly hollow pin be cut off; Shear more convenient, and be not easy to damage.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Hydraulic oil drain device of the present utility model, involved equipment, answered land used relatively more extensive in the prior art, do not repeat them here, the utility model emphasis is the unitary construction being made up of a hydraulic oil drain device separation equipment.
A kind of hydraulic oil drain device as shown in Figure 1, comprises housing 1, is provided with top connection 2 inside described housing 1; On the downside of described top connection 2, piston 3 is installed; Also hydraulic liftout apparatus is installed below described piston 3; The housing wall ejecting end top of described hydraulic liftout apparatus is embedded with hollow pin 4; Inside described housing 1, tail end is provided with lower contact 9; Described hydraulic liftout apparatus 3 is U-tube 5; Hydraulic oil is marked with in described U-tube 5; Described U-tube 5 one end is provided with seben 6, and the other end is provided with pad 7; Described seben 6 is fitted with hollow pin 4, and described pad 7 is fitted with piston 3.
Described hollow pin 4 is provided with O type circle with housing installation place.
On the upside of described hollow pin 4, inner face is provided with two sealing limited blocks 8.
Described U-tube 5 near hollow pin 4 one end than more than the long twice in close piston 3 one end.
During utility model works, top connection and lower contact directly connect oil pipe, when well workover, hydraulic pump is utilized to exert pressure in well, liquid enters in bleeder annular chamber, is directly pressed down by piston, due to U-tube near hollow pin one end than more than the long twice in close piston one end, so hydraulic pressure dynamics is larger, can disposablely directly hollow pin be cut off.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
