Abstract
The utility model relates to a novel leakproof pipe joint structure which comprises a device body, a pipe joint and a sealing ring, wherein the device body is connected with the pipe joint by screw thread; the sealing ring is sheathed on the outer wall of the pipe joint; and the pipe joint and the device body are sealed by the sealing ring. The novel leakproof pipe joint structure is simple and good in sealing performance, and can be widely applied to the field of mechanical equipment connection.
Description
Technical field
The utility model relates to a kind of equipment connection set, particularly relates to a kind of novel anti-leak pipe joint structure.
Background technique
The pipe joint that uses in the hydraulic system all is a plane sealing, leans on two sealing surfaces that seal ring is compressed and reaches sealing function, in use, and the phenomenon that fastening piece can become flexible, thus make the decrement of seal ring reduce, and sealability descends and leakage of oil.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, the novel anti-leak pipe joint structure of good sealing effect.
In order to address the above problem, the utility model adopts following technological scheme:
A kind of novel anti-leak pipe joint structure comprises apparatus body, pipe joint and seal ring, and apparatus body and pipe joint are with seal ring through being threaded on the pipe joint outer wall, between pipe joint and the apparatus body through the seal ring sealing.
A kind of novel anti-leak pipe joint structure; Comprise welded joint body, coupling nut, welding adapter and seal ring; The welded joint body is taken over welding and is linked together through coupling nut, and the welding adapter outside is with seal ring, and welded joint body and welding seal through seal ring between taking over.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is simple in structure, and is easy for installation, and when fastening piece was loosening, seal ring still can not reduce the performance of sealing, thereby prevented the phenomenon that medium is revealed.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the another kind of mounting type schematic representation of the utility model;
Fig. 3 improves preceding mounting structure schematic representation for pipe joint;
Fig. 4 for pipe joint improve before another kind of form schematic representation.

Embodiment
Embodiment one
A kind of novel anti-leak pipe joint structure; As shown in Figure 1, comprise apparatus body 1, pipe joint 3 and seal ring 2, apparatus body 1 and pipe joint 3 are through being threaded; Be with seal ring 2 on the pipe joint outer wall, seal through seal ring 2 between pipe joint 3 and the apparatus body 1.Pipe joint 3 is screwed into apparatus body through connecting screw thread, and axial sealing ring is born sealing function, moves back under the situation of button at the connection screw thread, and axial sealing ring still works, and can not cause leakage.
Embodiment two
A kind of novel anti-leak pipe joint structure; As shown in Figure 2; Comprise welded joint body 4, coupling nut 5, welding adapter 6 and seal ring 2; Welded joint body 4 and welding are taken over 6 and are linked together through coupling nut 5, and welding is taken over 6 outsides and is with seal ring 2, between welded joint body 4 and welding take over 6 through seal ring 2 sealings.Coupling nut 5 through screw thread with welded joint body 4 and welding take over 6 be linked together, axial sealing ring is born sealing function, moves back at coupling nut under the situation of button, axial sealing ring still works, and can not cause leakage.
Before the improvement, the pipe joint of plane sealing such as Fig. 3, shown in Figure 4, in the using process, if because of reasons such as vibration cause coupling nut or connect screw thread moving back button, the decrement of plane sealing will reduce, thereby causes leakage of oil.
Claims (2)
