In sum, in order to solve the technical problem that above-mentioned pipe joint exists, need to design a kind of not easily corrosion and working life longer pipe joint.
Model utility content
The purpose of this utility model is the problems referred to above existed for prior art, propose a kind of not easily corrosion and working life longer pipe joint.
The purpose of this utility model realizes by following technical proposal: a kind of pipe joint, comprise joint body, described joint body axially offers the through hole of penetrator body, described joint body outer surface radial direction is provided with boss, described boss makes joint body be divided into integrated first joint and the second joint, first joint offers the first annular connecting groove around its end face axial, described first annular connecting groove makes the first pontes be the first interior tube body and the first outer tube body, first outer tube body madial wall is provided with the internal thread being positioned at the first annular connecting groove, second joint offers the second annular connecting groove around its end face axial, described second annular connecting groove is the second attachment portion is the second interior tube body and the second outer tube body, second interior tube body outer side wall is provided with the outside thread being positioned at the second annular connecting groove.
In above-mentioned a kind of pipe joint, described first outer tube body offers the first oil inlet hole running through the first outer tube body, described first oil inlet hole communicates with internal thread, and the second joint offers the second oil inlet hole, and described second oil inlet hole communicates with outside thread.
In above-mentioned a kind of pipe joint, described first joint is outer-hexagonal body.
Compared with prior art, the utility model has following beneficial effect:
By offering the first annular connecting groove on the first joint, second joint is offered the second annular connecting groove, and the internal thread being used for being connected and fixed or outside thread are arranged in the first annular connecting groove and the second annular connecting groove, after connection, externally connected pipe is fixed in the first annular connecting groove or the second annular connecting groove, and liquid passes through the madial wall of the first interior tube body and the second interior tube body, under the effect of the first interior tube body and the second interior tube body, outside thread or internal thread not easily with liquid comes into contact, therefore, fundamentally avoid corrosion after internal thread or outside thread and liquid comes into contact.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model one preferred embodiment.
In figure, 100, joint body; 110, through hole; 130, boss; 140, the first joint; 141, the first annular connecting groove; 142, the first interior tube body; 143, the first outer tube body; 144, the first oil inlet hole; 150, the second joint; 151, the second annular connecting groove; 152, the second interior tube body; 153, the second outer tube body; 154, the second oil inlet hole.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of pipe joint, comprise joint body 100, described joint body 100 axially offers the through hole 110 of penetrator body 100, described joint body 100 outer surface radial direction is provided with boss 130, described boss 130 makes joint body 100 be divided into integrated first joint 140 and the second joint 150, first joint 140 offers the first annular connecting groove 141 around its end face axial, described first annular connecting groove 141 makes the first joint 140 be divided into the first interior tube body 142 and the first outer tube body 143, first outer tube body 143 madial wall is provided with the internal thread being positioned at the first annular connecting groove 141, when the first joint 140 is connected with externally connected pipe, externally connected pipe is correspondingly provided with outside thread, externally connected pipe and the first outer tube body 143 are threaded connection, thus externally connected pipe enters in the first annular connecting groove 141, second joint 150 offers the second annular connecting groove 151 around its end face axial, described second annular connecting groove 151 is that the second joint 150 is divided into the second interior tube body 152 and the second outer tube body 153, second interior tube body 152 outer side wall is provided with the outside thread being positioned at the second annular connecting groove 151, when the second joint 150 is connected with externally connected pipe, externally connected pipe is correspondingly provided with internal thread, externally connected pipe and the second joint 150 are threaded connection, thus make externally connected pipe enter in the second annular connecting groove 151, after connection, externally connected pipe is fixed in the annular connecting groove 151 of the first annular connecting groove 141 or the second, and liquid passes through the madial wall of the first interior tube body 142 and the second interior tube body 152, under the effect of the first interior tube body 142 and the second interior tube body 152, outside thread or internal thread not easily with liquid comes into contact, therefore, fundamentally avoid corrosion after internal thread or outside thread and liquid comes into contact
As improvement, described first outer tube body 143 offers the first oil inlet hole 144 running through the first outer tube body 143, described first oil inlet hole 144 communicates with internal thread, and the second joint 150 offers the second oil inlet hole 154, and described second oil inlet hole 154 communicates with outside thread.
Existing pipe joint and socket substantially adopt and are threaded, and be threaded in the connect hours and cross for a long time or pipe joint and externally connected pipe all can be caused to dismantle in the situation such as joint corrosion or be difficult to dismantle, and when there is this situation, pipe joint often amputates by people, in externally connected pipe at the new pipe joint of upper access, so, then cause waste, and on the first outer tube body 143, offer the first oil inlet hole 144, after second joint 150 is offered the second oil inlet hole 154, when the joint of pipe joint and externally connected pipe cannot be opened, then inject lubricant oil in the first oil inlet hole 144 and the second oil inlet hole 154, and joint is by after oil lubrication, its dismounting difficulty is greatly lower, therefore, be more prone to dismounting.
As improvement, described first joint 140 is outer-hexagonal body, adopts outer-hexagonal body, facilitates when this pipe joint and other externally connected pipe dismounting and exerts a force.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
