Description
Technical field
The present invention relates to pipeline connection areas, and in particular to a kind of protective cover of pipe joint screw thread.
Technical background
Petrochemical Pipe Joints are the fastening means between pipeline and pipeline, are the connections that can be dismounted between element and pipeline
Point, Petrochemical Pipe Joints act as indispensable key player in the tube.However there can be section of tubing connector because of demand
And the case where not needing connection temporarily, at this moment dust enters the connector of port upward in order to prevent, generally will use simple
Internal screw thread protective cover carry out jacket because the connector of port upward compared to port laterally and it is lower to connector be easier to enter
Dust, if however, steam, time can be gathered in the thread pitch inside internal screw thread protective cover under moist environmental condition
One length singly can not be mouldy smelly, or even corrosion screw thread, and the protective cover for causing the problem of can not unloading, therefore being covered need to have logical as far as possible
The characteristic of gas.
Summary of the invention
The present invention provides a kind of protective cover of pipe joint screw thread, can ventilate when screwing protective case to screw thread mouth, with
Inner and outer air pressure is balanced, is preferably screwed, and play the effect of waterproof.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of guarantor of pipe joint screw thread
Shield, including thread bush ontology, wherein the thread bush ontology includes front wall surface, set end face and set internal screw thread, the front
Wall surface is interconnected to form polygon outer profile, there is oblique arc ventilating part on the front wall surface, and the oblique arc ventilating part includes
Tiltedly above and arc sliding surface, it is described tiltedly above for from the straight sidewall it is inward-facing tilt upward extend into the set internal screw thread put down
Face, the arc sliding surface are located at the oblique lower section above, and the arc sliding surface is to connect the front wall surface and the set internal screw thread
It is described oblique above to form port between the arc sliding surface and to the tiltedly arcwall face of direction protrusion above.
Preferably, further including for lead the way on the inside of exit guide to the arc sliding surface.
Preferably, the inside lead the way for from the arc sliding surface close to set internal screw thread side surface along described
The axially extending direction of thread bush is gradually distance from the hollow channel of the set end face.
Preferably, further including the flaring diversion face conducive to Quick water-inducing, the flaring diversion face is to draw from the inside
The outside inner wall upper end in road is gradually distance from the arcwall face of the inner wall of opposite side along the extending direction that the inside is led the way.
Preferably, further including the return water drainage trough for enhancing the front wall roughness.
Preferably, the return water drainage trough is to be recessed inwardly from the outer ledge of the arc sliding surface and towards far from the set
End face side extend and the gradually smaller vertical bar slot of cup depth, the return water drainage trough along the arc sliding surface outer ledge
Horizontal interval arrangement.
Preferably, the slot side stress item that stress is skidded occurs when further including for preventing rotation.
Preferably, the slot side stress item is from the outside oppositely extending protrusion in the ipsilateral side of the return water drainage trough
Item.
In conclusion the invention has the following beneficial effects: that can ventilate when screwing protective case to screw thread mouth, with balance
Inner and outer air pressure between extraneous and flank, prevents local flatulence and preferably screws, and play the effect of waterproof, while again
The steam dropped into flank can be carried out to ventilation to air-dry.
Detailed description of the invention
Fig. 1 is this overall schematic of thread bush.
Fig. 2 is this entirety of thread bush sectional structure chart.
In figure: 11, front wall surface, 21, tiltedly above, 22, arc sliding surface, 3, inside lead the way, 4, flaring diversion face, 5, return water draws
Chute, 6, slot side stress item.
Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
Embodiment 1, as shown in Figure 1 to Figure 2.Protective cover in the technical program is best suited for the pipe joint of port upward
End is connected with each other between front wall surface 11, so that the vertical view outer profile of thread bush ontology is polygon, when by thread bush ontology pair
When quasi- pipe joint external screw thread screws, due to there is oblique arc ventilating part on the surface of front wall surface 11, the interior of thread bush ontology is connected
Outside, so, the external screw thread of pipe joint is engaged process with set internal screw thread contact can be more smooth, avoids gas in pipe joint
It is extruded generation resistance and leads to screw more difficulty, after screwing, tiltedly the emptying aperture above between 21 and arc sliding surface 22 is spiral shell
At line face and extraneous ventilation, when rain or other unexpected liquid splash down when thread bush ontology, due to oblique 21 side above
To tilting upward from the outside to the core, therefore tiltedly splashing water droplet on 21 above can then slide again, and arc sliding surface 22 is convex due to itself
The surface risen, it more difficult to allow fluid to slide into thread bush body interior direction, moreover, if there is liquid runs down thread bush ontology
Opening is gradually spread by the tension of water, so that filled with liquid between occlusion flank, it may once for a long time, common protection
Cover can be corroded flank, and if have oblique arc ventilating part, certain air flowing can be formed by oblique arc ventilating part, gradually
The case where air-drying liquid, preventing burn into from getting rusty appearance.
Preferably, it is also used to be discharged to accidentally enter at the inside of arc sliding surface 22 to draw on the inside of 22 internal liquid of arc sliding surface
Road 3, when unexpected generation, liquid enters flank side with oblique above 21 or arc sliding surface 22, then can enter inside and lead the way 3 mouthfuls,
It leads the way and 3 runs underneath on the outside of the screw thread mouth of protective cover along inside, wherein 3 equivalent width if inside is led the way may result in liquid
Body is stuck in inside and leads the way in 3, therefore can also prevent a little liquid holdup from leading the way in 3 in inside by flaring diversion face 4.
From tiltedly above 21 and arc sliding surface 22 on the liquid that flows back to, the return water drainage trough 5 on the downside of oblique arc ventilating part can be passed through
Flow down, be unlikely to liquid and arbitrarily flowed on front wall surface 11, moreover, due to return water drainage trough 5 be it is spaced, can
To act on return water drainage trough 5 in stress, when rotation, can be more stable, prevents from turning to and skid.At this moment, finger can contact
On slot side stress item 6, slot side stress item 6 can prevent finger from skidding in a vertical direction, and due to being reversed extension item,
So the resistance gathered can be generated to finger, keep the finger point of application more stable.
