Description
Technical field
The utility model relates to a kind of metering device of oil well head, particularly measures the oil nozzle cover.
Background technology
Metering oil nozzle cover is well head a kind of oil transportation metering device commonly used, the metering oil nozzle cover that uses at present mainly is made up of plug, threeway body and oil nozzle etc., oil nozzle is connected with taper thread in the body endoporus, oil nozzle is provided with the nozzle that has aperture of higher hardness, and the time of the aperture by aperture, the pressure reduction of nozzle ends crude oil and crude oil circulation just can measure the crude oil volume and weight that oil nozzle is exported.
In the metering oil nozzle cover that uses at present, there is following problem:
1, is connected for taper thread between the straight tube port of threeway body and the plug; because the error of machining accuracy; occur sometimes after tightening making plug be difficult to the phenomenon of dismantling from body because screw thread bites; in addition when running into high pressure oil wells; the former wet goods regular meeting of ejecting from oil nozzle causes damage to the not high plug end face of hardness, and these have caused bad consequence all for product quality and on-the-spot the use.
2, the straight-tube portion of body is to be pegged graft by two sections round steel boring processing backs of same diameter to be welded, and weld seam is arranged on the cylindrical, exists material and technology cost higher, the inaesthetic problem of weld seam.
3, be interference fit between nozzle cylindrical and the oil nozzle body endoporus, machining accuracy and assembly technology are had relatively high expectations.
The utility model content
The purpose of this utility model is to oil well head provides a kind of security reliability height, the metering oil nozzle cover that manufacturing cost and use cost is lower.
The technical solution adopted in the utility model is: metering oil nozzle cover is mainly by threeway body, oil nozzle, tapering seal head, and " zero " RunddichtringO, plug constitute; Female joint two ends and middle cylindrical place are provided with straight internal thread in the threeway body, and male joint is connected the back girth welding with the internal thread of female joint one end, and by-pass connection is connected the back girth welding with the internal thread at the middle cylindrical of female joint place; Plug is connected with the internal thread of the female joint other end, the root of this internal thread is provided with internal conical surface, head is provided with one section straight hole, one end has the tapering seal head device of male cone (strobilus masculinus) between plug end face and female joint inner conical surface, the male cone (strobilus masculinus) of tapering seal head and the inner conical surface of female joint coincide, and compressed by plug and to realize the tapering sealing, the plug screw thread tail end be provided with the bipassage ring connected in star, be provided with " zero " RunddichtringO in the groove, cooperated auxiliary seal and dustproof effect with the female joint endoporus; Oil nozzle is connected with the internal thread of male joint in the threeway body endoporus, oil nozzle body endoporus is the concentric circle holes in two kinds of apertures, big nose end is provided with internal thread, the junction in two holes is inner conical surface, one end of nozzle is male cone (strobilus masculinus), and install in the macropore of oil nozzle body, the inner conical surface of its male cone (strobilus masculinus) and oil nozzle body coincide, and compresses the realization conical surface seal by hold-down bolt.
Above-mentioned tapering seal head adopts the high-carbon steel Quenching Treatment.
Compared with prior art, the utility model has the advantages that manufacturing process is simple, cost is low, good sealing effect, anti-impact erosion, the oil nozzle replacement cost is low, the screw thread phenomenon of biting can not take place, and is safe and reliable.

The specific embodiment
As shown in Figure 1, a kind of metering oil nozzle cover, it is by male joint 1, and housing screw 2, oil nozzle 3, oil nozzle body 4, female joint 5, by-pass connection 6, tapering seal head 7, " zero " RunddichtringO 8, plug 9 constitute.Male joint 1 two ends are external screw thread, and wherein the screw thread of an end is taper thread, and the screw thread of the other end is straight thread, and straight thread end endoporus is provided with the tapering internal thread that is connected with oil nozzle body 4, and by-pass connection 6 one ends are the tapering internal thread, and the other end is straight external screw thread; The internal thread that the straight thread end of male joint 1 is corresponding with female joint 5 one ends connects the back girth welding to be fixed, weld seam is positioned at female joint 5 end faces, the internal thread perpendicular to axis that the centre position arranges on the external screw thread of by-pass connection 6 and female joint 5 cylindricals is connected, mode by welding is fixed the two girth welding, and this structure is the threeway body of metering oil nozzle cover; The end that oil nozzle body 4 has outer cone thread is provided with internal thread, the other end is that diameter is less than the circular hole of internal thread bottom diameter, its internal thread bottom outlet root is provided with internal conical surface, the male cone (strobilus masculinus) that nozzle 3 one ends arrange and this internal conical surface coincide, the contact sealing of the two conical surface compresses the back by housing screw 2 and realizes; The connecting thread of female joint 5 other ends and plug 9 is straight thread; the tapering seal head 7 that is provided with male cone (strobilus masculinus) places between the inner conical surface of plug 9 end faces and female joint 5 internal thread roots; plug tap face cone degree is identical; compress sealing by plug 9; this structure cooperates with twice " zero " RunddichtringO 8 that plug screw-thread ending place arranges; not only sealing is reliable, and to its proofing dust and protecting effect of connecting thread, makes the easier dismounting of plug.
In the utility model, because plug 9 is connected with the straight thread that is connected to of female joint 5, and adopted effective dust prevention, its taper fit structure only to need to apply on the plug 9 less screwing force and just can realize sealing reliably, so the thread biting locking phenomenon can not take place between the two.The oil nozzle structure that nozzle 3, oil nozzle body 4 and housing screw 2 constitute has not only reduced difficulty of processing, has improved working (machining) efficiency, and has been easy to change nozzle 3, thereby reduced the manufacturing cost and use cost of oil nozzle 3 greatly.In the threeway body because male joint 1 adopted the less steel of diameter, with female joint 5 be welded as the end face welding, saved material, improved effect again.
