Abstract
The utility model discloses a seal joint. The seal joint comprises a seal gasket, a movable joint and a pipe joint, the movable joint is in threaded connection with the pipe joint through a nut, the seal gasket is arranged between the movable joint and the pipe joint, and a seal gasket locating structure is arranged on the pipe joint. The seal joint can accurately locate and fix the seal gasket and improve the seal performance of the whole pipeline.
Description
Technical field
The utility model relates to SEALING FITTING.
Background technique
Joint in the pipeline can be provided with gasket seal usually; if the gasket seal position is not accurate enough in the installation process; tend to cause herein seepage; influence the sealability of whole pipeline; at present; the order of accuarcy of the mounting point of gasket seal often depends on artificial experience, and its levels of precision has much room for improvement.
Summary of the invention
Technical problem to be solved in the utility model just provides simple in structure, easy to operate practicality, can accurately locate the SEALING FITTING of gasket seal.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, SEALING FITTING, comprise that gasket seal, union, pipe joint, described union and described pipe joint are spirally connected by nut, described gasket seal is located between described union and the described pipe joint, and institute's pipe joint is provided with the gasket seal position structure.
As a kind of preferred scheme, described position structure is groove.
As the preferred scheme of another kind, described position structure is projection.
Preferably, described projection is annular.
The utility model SEALING FITTING is by being provided with position structure at described pipe joint, and effectively the line seal problem that causes owing to the diaphragm seal mounting point is inaccurate has effectively been avoided in location and fixing described gasket seal.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model seal joint structure schematic representation;
Fig. 2 is the pipe joint schematic representation among Fig. 1.
Embodiment
Extremely shown in Figure 2 as Fig. 1, be the utility model SEALING FITTING, comprise that gasket seal 1, union 2, pipe joint 3, described union 2 are spirally connected by nut 4 with described pipe joint 3, described gasket seal 1 is located between described union 2 and the described pipe joint 3, and institute's pipe joint 3 is provided with the gasket seal position structure.
In the present embodiment, described position structure is projection 31, and described protruding 31 is ring-type.Described protruding 31 offset and play the effect of location with described gasket seal 1, described annular projection also can change a plurality of point-like projectioies into, also can establish groove as position structure at described pipe joint 2, described gasket seal is fastened on to position in the described groove gets final product.
During installation, earlier pipe fitting to be connected is connected to respectively on described union 2 and the described pipe joint 3, be enclosed within described gasket seal 1 on the described pipe joint and be against on described protruding 31, tightening described nut 4 at last makes described union 2 fixedly connected with described pipe joint 3, described gasket seal 1 be pressed on described protruding 31 and the end of described union 2 between, thereby play the effect of sealing.
