Abstract
The utility model relates to a hydraulic adjustable right-angle connector which belongs to the technical field of hydraulic pieces. The right-angle connector is connected with the inlet and the outlet of hydraulic equipment and a pipeline, and comprises a right-angle body with threads on both ends; one end of the right-angle body is provided with a nut and a short circuit which is adapted with the pipeline, and the other end of the right-angle body is provided with an adjusting nut, goes out of the adjusting nut, and is screwed with the inlet and the outlet of the hydraulic equipment; an axial seal piece is arranged between the other end of the right-angle body and the adjusting nut; and the end surface of the adjusting nut is provided with a plane seal piece. Compared with traditional adjustable right-angle connectors, the right-angle connector omits the threaded inner connector which has a complicated structure and higher cost; in addition, because the other end of the right-angle body is directly arranged on the inlet and the outlet of the hydraulic equipment and completes axial and plane sealing through the adjusting nut, the hydraulic adjustable right-angle connector can adapt to the connection between the hydraulic equipment and the pipeline in a plurality of small spaces.
Description
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of hydraulic fitting, belongs to the hydraulic parts technical field.
Background technique
In hydraulic pressure and lubrication system, adopted the adjustable angle coupling of all size at present.But find in the practice that these angle couplings have generally used cutting ferrule or metallic gasket, its use initial stage is good, but in case the maintenance back leakage of oil of disintegrating is just unavoidable.Hydraulic pressure and lubrication system adjustable union elbow commonly used is shaped on screw thread at the two ends of right angle body 1 as shown in Figure 1, and an end of right angle body 1 is equipped with nut 2, is used to connect pipeline by nut 2 and being spirally connected of short circuit 3; The other end at right angle body 1 is set with screw thread spigot (or being the outside thread pipe nipple) 4, wherein screw thread spigot 4 is used to connect the import and export at hydraulic equipment (as oil pump, oil cylinder etc.), by adjusting nut 5 the screw thread spigot 4 and the other end of right angle body 1 are fixed (perforate 6 is arranged on the adjusting nut 5, penetrate perforate 6 with steel wire adjusting nut 5 is clamped in the draw-in groove of right angle body 1 the other end).As can be seen, the other end structure that existing adjustable union elbow connects on hydraulic equipment is imported and exported is complicated, use the cost of screw thread spigot 4 higher, and because screw thread spigot 4 takes up room bigger, therefore incompatible be installed on the narrower hydraulic equipment of space range (during the hydraulic equipment pipe arrangement since pipe arrangement in casing, so the space is smaller).
The model utility content
The technical problems to be solved in the utility model is, proposes a kind of adaptation and is installed on the narrower hydraulic pressure installation of space range and designs simplification, adjustable angle coupling that cost is low.
The technical solution of the utility model is: a kind of hydraulically adjustable angle coupling, be used to connect the import and export and the pipeline of hydraulic equipment, comprise that two ends are shaped on the right angle body of screw thread, one end of described right angle body is equipped with nut and is used to connect the short circuit of described pipeline, it is characterized in that: the other end of described right angle body is equipped with adjusting nut and passes the direct import and export with described hydraulic equipment of adjusting nut and is spirally connected, be provided with axial seal between the other end of described right angle body and the adjusting nut, the end of described adjusting nut is provided with flat seal.
The beneficial effect of hydraulically adjustable angle coupling of the present utility model is: compare existing adjustable angle coupling, not only saved complex structure, the higher screw thread spigot of expense; And because the other end of right angle body is directly installed on the import and export of hydraulic equipment, and finish axially and plane sealing by adjusting nut, therefore can adapt to being connected of the narrower hydraulic equipment of many space ranges and pipeline.
Technique scheme be: have an O type groove on the other end side face of described right angle body, described axial seal is an O type circle that is filled in the O type groove; The end of described adjusting nut is provided with the 2nd O type groove, and described flat seal is the 2nd O type circle that is filled in the 2nd O type groove.
Description of drawings
Below in conjunction with accompanying drawing hydraulically adjustable angle coupling of the present utility model is described further.
Fig. 1 be existing adjustable angle coupling partly cut open structural representation.
Fig. 2 be the utility model embodiment hydraulically adjustable angle coupling partly cut open structural representation.
Fig. 3 be the right angle body that decomposes among Fig. 2 partly cut open structural representation.
Fig. 4 be the adjusting nut that decomposes among Fig. 2 partly cut open structural representation.
Embodiment
Embodiment
The hydraulically adjustable angle coupling of present embodiment is used to connect the import and export and the pipeline of hydraulic equipment 100 as shown in Figure 2, comprises that two ends are shaped on the right angle body 1 of screw thread, and an end of right angle body 1 is equipped with nut 2 and is used to connect the short circuit 3 of pipeline.The other end of right angle body 1 is equipped with adjusting nut 5 and passes adjusting nut 5 import and export direct and hydraulic equipment 100 and is spirally connected.Between the other end of right angle body 1 and adjusting nut 5, be provided with axial seal 7, be provided with flat seal 8 in the end of adjusting nut 5.
As figure Fig. 2, shown in Figure 3, have an O type groove 9 on the other end side face of right angle body 1, axial sealing ring 7 is O type circles that are filled in the O type groove 9.As Fig. 2, shown in Figure 4, be provided with the 2nd O type groove 10 in the end of adjusting nut 5, planar seal ring 8 is the 2nd O type circles that are filled in the 2nd O type groove 10.
The advantage of the hydraulically adjustable angle coupling of present embodiment has:
1, cancelled screw thread spigot on the existing adjustable angle coupling, directly on right angle body machining screw has reduced the height of pipe joint, thereby adapts to being connected of the narrower hydraulic equipment of space range and pipeline.
2, changed the mounting structure and the function of adjusting nut, be placed in the axial seal and the flat seal that is placed on the adjusting nut of right angle body 1 the other end respectively, avoided leakage of oil or oil impregnate phenomenon well, used really good.
3, adjustable angle coupling is simple in structure and practical, from angle easy to process, fluting and adjusting nut internal recessing on the right angle body have been adopted, reduced difficulty of processing with the right-angle type debugged joint ratio in the past, done a screw thread spigot less, processing cost will significantly decrease when having saved material.
Hydraulically adjustable angle coupling of the present utility model is not limited to the various embodiments described above, such as, 1) can save an O type groove 9 and the 2nd O type groove 10; 2) axial seal 7 and flat seal 8 also can be parcel or other forms of Sealing; Or the like.All employings are equal to replaces the technological scheme that forms, and all drops on the protection domain of the utility model requirement.
