Description
Technical field
The utility model relates to Oil/gas Well well logging field, particularly relates to a kind of floating-tube type outlet valve.
Background technique
When High Temperature High Pressure Oil/gas Well well logging construction, when holding up preventer, when opening test strobe, frequent appearance is due to fault gate or open gate excessive velocities and cause the high-pressure oil gas in well to scurry into suddenly the situation of lubricator, the gas of lubricator inner space is compressed suddenly, can only be extruded instantaneously from choke tube by the gas sharply compressed, thus cause the cable at choke tube place to be produced instantaneous high-temperature by gas current friction, the cable wire of superhigh temperature is sharply quenched by the water arrived simultaneously, the portion outer layer steel wire of cable is caused to quench disconnected, the logger very easily occurring to be caused by cable breakage falls well accident.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of reasonable in design, good exhaust effect, the floating-tube type outlet valve of energy available protecting cable, guarantee use safety.
For this reason, the technical solution of the utility model is as follows:
A kind of floating-tube type outlet valve, comprise valve casing, hollow valve core and air outlet adapter, described valve casing is tubulose, its lower end closed, upper end forms opening, and described air outlet adapter is arranged on this opening, is provided with the air outlet hole that the inner chamber of described valve casing is connected with free surrounding space at air outlet adapter center; Bottom air outlet adapter side valve casing 1 on be provided with a radial air inlet mouth; Described hollow valve core is movably arranged on the intracavity bottom of described valve casing, is provided with projection in hollow valve core upper end, when the inner chamber of valve casing be full of liquid make hollow valve core float up to valve shell cavity top time, air outlet hole can be closed by described projection.
Preferably, be provided with a taper recess in the middle part of the inner chamber bottom surface of described valve casing, the lower ending opening place of described air outlet hole is tapered and adapt with the shape of described projection.
Described hollow valve core is made up of a tubular shell and a lid, the upper end closed of described tubular shell, and lower end is provided with the opening suitable with described lid, and described lid is arranged on this opening.
Described valve casing and described air outlet adapter are threaded, and are also provided with seal ring at the connection part place of described air outlet adapter and valve casing.
The utility model smart structural design, rationally, when the gas of lubricator inner space is compressed suddenly, described gas can enter in valve casing through radial air inlet mouth fast, and by not discharged rapidly by the air outlet hole that hollow valve core is closed, realize the object of gas discharging will sharply compressed instantaneously, effectively avoid occurring that cable is quenched disconnected phenomenon, ensure use safety, reliability is high, thus extends the working life of cable; When pressurized gas are discharged complete, liquid enters and is full of valve casing, and hollow valve core can slowly float, and along with the increase of pressure, makes hollow valve core contact more and more tighter with the air outlet hole on air outlet adapter, finally reaches the effect of seal fluid after drained gas.The utility model overall structure is simple, compact, is easy to realize, and its cost is low, is beneficial to wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the structural representation of floating-tube type outlet valve of the present utility model;
Fig. 2 is the structural representation of hollow valve core in Fig. 1.
Embodiment
Be described in detail below in conjunction with the structure of accompanying drawing to floating-tube type outlet valve of the present utility model.
See the embodiment of Fig. 1 and Fig. 2.This floating-tube type outlet valve comprises: valve casing 1, hollow valve core 2 and air outlet adapter 3.
Described valve casing 1 is tubulose, its lower end closed, and upper end forms opening, and described air outlet adapter 3 is arranged on this opening, is provided with the air outlet hole 31 that the inner chamber of described valve casing 1 is connected with free surrounding space at air outlet adapter 3 center.Bottom air outlet adapter 3 side valve casing 1 on be provided with a radial air inlet mouth 4.Described hollow valve core 2 is movably arranged on the intracavity bottom of valve casing 1, is provided with protruding 21 in hollow valve core 2 upper end, when the inner chamber of valve casing 1 be full of liquid make hollow valve core 2 float up to valve casing 1 inner cavity top time, air outlet hole 31 can be closed by described protruding 21.
Concrete, the inwall of described valve casing 1 upper end open is provided with internal thread, and air outlet adapter 3 is provided with the outside thread suitable with this internal thread.Preferably, seal ring 32 is also provided with, to improve sealing effect at air outlet adapter 3 and the connection part place of valve casing 1.
See Fig. 2, described hollow valve core 2 is made up of a tubular shell 22 and a lid 23.The upper end closed of described tubular shell 22, lower end is provided with the opening suitable with described lid 23, and described lid 23 covers on this opening.
Preferably, in the middle part of the inner chamber bottom surface of described valve casing 1, be provided with a taper recess 11, it can improve the balance of hollow valve core 2 when floating, and can match with the air outlet hole 31 on air outlet adapter 3 preferably, improves tightness, good sealing effect.The lower ending opening place of air outlet hole 31 is tapered and adapt with the described shape of protruding 21, is convenient to hollow valve core 2 and matches with it, promotes the sealing effect of hollow valve core 2 further.
During installation, radial air inlet mouth 4 is connected on lubricator by a union.During work, when the gas of lubricator inner space is compressed suddenly, this gas can enter in valve casing 1 through radial air inlet mouth 4 fast, and discharged rapidly by the air outlet hole 31 do not closed by hollow valve core 2, realize the object of gas discharging will sharply compressed instantaneously, effectively avoid occurring that cable is quenched disconnected phenomenon, ensure use safety, extend the working life of cable.When pressurized gas are discharged complete, liquid slowly overflows after outlet valve from lubricator, because the buoyancy of hollow valve core 2 in liquid (oil, aqueous mixtures) is greater than the gravity of himself, so be full of whole valve casing 1 along with liquid, hollow valve core 2 can slowly float.Along with the increase of pressure, hollow valve core 2 contacts more and more tighter with the air outlet hole 31 on air outlet adapter 3, finally reaches sealing effect.This floating-tube type exhaust structure is simple, compact, use safety, reliable.
