It is clear, it is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of oil field screw-type tubing nipple of the outer silk of double end, such as Fig. 1 and Fig. 4, including tubing nipple part ontology 1, peace
Fill head 2, the screw thread 3 that is screwed on, spliced eye 4, mounting rod 5, functor 6, PVC gum cover 7, block head 11 and indicating label 12, the oil
The equal integral type in upper and lower ends portion of pipe pipe nipple part ontology 1 is connected with mounting head 2, and the outer surface of mounting head 2 offers the spiral shell that is screwed on
Line 3, using the structure of silk outside double end, the outer surface two sides of tubing nipple part ontology 1 offer perforative spliced eye 4, oil pipe
Mounting rod 5 is laterally installed in the middle part of the inner cavity of pipe nipple part ontology 1, mounting rod 5 is telescopic rod, and the both ends of mounting rod 5 are inserted in
In spliced eye 4, the outside of mounting rod 5 is fixed with functor 6, and movable sleeve is gone back equipped with PVC gum cover in the outside of tubing nipple part ontology 1
The socket position of 7, PVC gum covers 7 is the outside of spliced eye 4, and the front and rear surfaces of PVC gum cover 7, which are also sticked to have, distinguishes pipe fitting function class
The indicating label 12 of type, for being mounted with that the tubing nipple of different function part 6 distinguishes；
Mounting rod 5 includes the outer tube 51 at middle part and the inner sleeve 52 at both ends, such as Fig. 2, the interior end pipe of two inner sleeves 52
Body is inserted in the interior intracavitary of outer tube 51, and spring part 9 is also installed in the gap of plugging position, i.e. the both ends of mounting rod 5
It can be inwardly compressed, the entire length of mounting rod 5 is shortened, the two sides of outer tube 51 are vertically fixed to be installed with auxiliary stopper peace
Shelve 10, be used for fixed function part 6 so that mounting rod 5 connect with functor 6 it is more firm, be not susceptible to misplace move；
The cross sectional shape of spliced eye 4 is adapted with the both ends shape of mounting rod 5, is flat rectangle, such as Fig. 3, can be prevented
Only mounting rod 5 rotates in spliced eye 4；
The inner surface of PVC gum cover 7 and the contact site of spliced eye 4 are installed with the block head 11 of protrusion, such as Fig. 4, block head
11 size is adapted with spliced eye 4, for spliced eye 4 to be sealed.
When work, required functor 6 is socketed in the outside of mounting rod 5 first, then compresses the both ends of mounting rod 5,
So that the entire length of mounting rod 5 shortens, facilitates and the mounting rod 5 of one and functor 6 are put into tubing nipple part ontology 1
It is intracavitary, the position at 5 both ends of mounting rod is regulated, so that the both ends of mounting rod 5 are inserted into respectively in corresponding spliced eye 4, due to flat
Flat-shaped inserted terminal design, so that mounting rod 5, functor 6 are not susceptible to rotate, fixation is more firm, finally by PVC gum cover
7 are sheathed on the outside of spliced eye 4, and corresponding block head 11 carries out limit closure to mounting rod 5 out of outside insertion spliced eye 4,
The airtightness of device is improved, while mounting rod 5 also being avoided to stretch out.
Embodiment one
When functor 6 is 61 state of homogeneous seat, such as Fig. 5, the global shape of homogeneous seat 61 is truncated cone-shaped, and homogeneous seat 61
Upper surface and side are arcwall face, and the periphery of homogeneous seat 61 offers longitudinal diversion trench 8 along surface, due to diversion trench 8
It is opened up along the outer surface of the homogeneous seat 61 of truncated cone-shaped, so the shape that circumferential diversion trench 8 forms is up-small and down-big
Bell mouth shape.
The top surface of homogeneous seat 61 is arc-shaped concave, and crash-protective characteristics are strong, can effectively depressurize to liquid stream, so that liquid stream
Slow down, be convenient for homogeneous operation, the side of homogeneous seat 61 is convex face, the diversion trench that can be opened up with periphery bell mouth shape
8 match, and the liquid stream that top is flowed down carries out effective stream, homogeneous, improve the efficiency of internal liquid transport.
Embodiment two
When functor 6 is 62 state of filtering base, such as Fig. 6, the generally hemispheric filter screen structure part of filtering base 62, and
The distance between the bottom edge of filtering base 62 and the interior walls of tubing nipple part ontology 1 d are not more than 10mm, filtering base 62
Distance is smaller between 1 inner wall of bottom edge and tubing nipple part ontology, i.e. the bottom peripheral dimension and tubing nipple of filtering base 62
The inner wall size of part ontology 1 is close, can avoid bulky grain filter residue by causing filter effect undesirable.
Filtering base 62 uses hemispheric filter screen structure part, i.e. upper surface is spherical, has certain anti-impact pressure, leads
Flow effect, and if impurities in liquid filtered out by filtering base 62, i.e., drop down onto 62 bottom of filtering base along spherical surface, do not influence top
The whole filtering of filtering base 62, it is ingenious in design, so that the filter residue of accumulation will not influence the work of filtering, it is clear without often carrying out
Reason, operation are more easy.
The functor 6 that the utility model adds can be tied for the homogeneous seat 61 of upper and lower superposing type installation, the combination of filtering base 62
Structure can also be single homogeneous seat 61 or single 62 structure of filtering base, is optionally combined according to job requirement, and spliced eye
4, it can be multiple groups that mounting rod 5 and PVC gum cover 7, which install combined quantity, can be longitudinally mounted multiple in pipe nipple according to job requirement
Functor 6, it is vdiverse in function.
