Abstract
The utility model relates to an oil draining device, belonging to the petroleum extraction mechanical parts. A hollow oil draining shear pin is connected on the side surface of the oil draining body in a screw threaded way; a central hole is arranged in the middle part of the oil draining body, and four auxiliary oil draining holes are arranged at the surrounding of the central hole on the oil draining body. The oil draining device has the advantages of novel structure and oil draining assistance by utilizing the auxiliary oil draining holes, thus solving the problem that the old oil draining device has unsmooth oil drainage; after practical usage, the using effect is good and the production efficiency of the oil field is improved.
Description
Technical field
The utility model belongs to the oil exploitation mechanical part.
Background technology
The present impacting type bleeder that uses of oil field, because trip rod is after severing the draining shear pin, this draining shear pin has been stayed in the bleeder centre bore, because this centre bore physical dimension is limit and caused the bleeder draining not smooth, result of use is not good.
Summary of the invention
The utility model relates to a kind of bleeder, is trapped in and causes the not smooth problem of draining in the draining hole to solve present shear pin.The technical scheme that the utility model is taked is: the be threaded draining shear pin of hollow of the side of draining main body, there is centre bore at this draining main body middle part, and four auxiliary draining holes are arranged on the draining main body and around this centre bore.
During use, when the bump pin severed the draining shear pin, this draining shear pin was stayed the bleeder central hole, four auxiliary drainings in auxiliary draining hole.
The utility model advantage is a novel structure, utilizes the auxiliary draining in auxiliary draining hole, thereby has solved the not smooth problem of old-fashioned bleeder draining; Use through reality, result of use is good, has improved the production efficiency in oil field.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The be threaded draining shear pin 2 of hollow of the side of draining main body 1, there is centre bore 4 at this draining main body middle part, and four auxiliary draining holes 3 are arranged on the draining main body and around this centre bore.
Claims (1)
1, the be threaded draining shear pin of hollow of a kind of bleeder, the side of draining main body, there is centre bore at this draining main body middle part, it is characterized in that: four auxiliary draining holes are arranged on the draining main body and around this centre bore.
