Description

A kind of end face seal structure
Technical field
This utility model belongs to technical field of pipeline connection, specifically, is about a kind of end face seal structure.
Background technology
The internal and external threads connection sealing structure of existing pipeline mostly is and twines band on external screw thread or be coated with fluid sealant.External screw thread twines the mode of band, its inefficiency, thereby increases and it is possible to blocking water route or water appliance etc.;External screw thread is coated with the mode of fluid sealant, there is shortcomings such as working under hard conditions, easy polluted water, maintenance are inconvenient.
For solving the problems referred to above, the internal and external threads of existing pipeline connects sealing structure also the mode using end face seal.And use end face seal mode, often because seal washer by excessive compression, rupture, deform the disengaging problem such as sealing surface and cause seal failure, thus bring certain obstacle to its large-area applications.
Therefore, it is necessary to design a end face seal structure reliable, easy for installation.
Utility model content
The purpose of this utility model is to provide a kind of good sealing effect, end face seal structure easy for installation.
For achieving the above object, this utility model is by the following technical solutions:
A kind of end face seal structure, including the support member arranged the most from inside to outside, male element and internal thread tube piece, described male element and internal thread tube piece match, described internal thread tube piece is made up of the end of thread and connection end, described support member is provided with a through hole in its axial direction, so that current pass through, it is sheathed with a seal washer on one section of cylindrical of described support member, the external diameter of described seal washer is more than the internal diameter of the end of thread of internal thread tube piece, to guarantee that seal washer can effectively realize end face seal.
According to this utility model, described support member includes the first supporting section and the second supporting section, and the maximum outside diameter of described first supporting section is less than the maximum outside diameter of the second supporting section.
According to this utility model, the front end of described first supporting section is provided with the first introduction part of band taper, it is simple to support member inserts in male element.
Further, being provided with the second introduction part of band taper between described first supporting section and the second supporting section, be provided with the 3rd introduction part of band taper in described male element, described second introduction part matches with the 3rd introduction part, thus realizes the axial location of support member.
Further, described first supporting section, the second introduction part and the second supporting section are formed in one structure.
End face seal structure of the present utility model, it provides the benefit that design is ingenious, simple in construction, reliable, easy to use, is embodied in:
1, seal washer is sleeved on one section of cylindrical of support member, and the external diameter of seal washer is respectively greater than the external diameter of support member and the internal diameter connecting end of internal thread tube piece, to guarantee that seal washer can effectively realize end face seal;
2, the setting of support member, can effectively prevent seal washer to be distorted, radial deformation etc., so that it is guaranteed that its sealing effectiveness is good;
3, the maximum outside diameter of described first supporting section is less than the design of maximum outside diameter of the second supporting section, can effectively prevent support member because of flow action axially displaced in pipeline, realize the axial location of support member further;
4, described first introduction part, the second introduction part and the setting of the 3rd introduction part, it is simple to the installation of support member.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of support member of the present utility model and seal washer.
Fig. 2 is the assembling schematic diagram of support member, seal washer and male element.
Fig. 3 is the structural representation of end face seal structure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, end face seal structure of the present utility model is described in further detail.Should be understood that following example are merely to illustrate this utility model not for limiting scope of the present utility model.
Such as Fig. 1, shown in Fig. 2 and Fig. 3, for a kind of end face seal structure of the present utility model, including the support member 1 arranged the most from inside to outside, male element 2 and internal thread tube piece 3, described male element 2 and internal thread tube piece 3 match, described internal thread tube piece 3 is made up of the end of thread 31 and connection end 32, the internal diameter of the end of thread 31 of described internal thread tube piece 3 is more than the internal diameter connecting end 32, the axial direction of described support member 1 is provided with a through hole 11, so that current pass through, described support member 1 be radially provided with a seal groove 12, a seal washer 4 it is provided with in described seal groove 12, the external diameter of described seal washer 4 is respectively greater than the external diameter of described support member 1 and the internal diameter connecting end 32 of described internal thread tube piece 3, to guarantee that seal washer 4 can effectively realize end face seal.
The front end of described support member 1 is provided with the first introduction part 13 of band taper, it is simple to support member 1 inserts in male element 2.
Described support member 1 includes the first supporting section 10 and the second supporting section 20, the maximum outside diameter of described first supporting section 10 is less than the maximum outside diameter of the second supporting section 20, described first introduction part 13 is located on described first supporting section 10, and described seal groove 12 is located on described second supporting section 20.
Being provided with the second introduction part 30 of band taper between described first supporting section 10 and the second supporting section 20, be provided with the 3rd introduction part 21 of band taper in described male element 2, described second introduction part matches with the 3rd introduction part, thus realizes the axial location of support member.
Described first supporting section the 10, second introduction part 30 and the second supporting section 20 are formed in one structure.
During use, first seal washer 4 is sheathed in the seal groove 12 of support member 1;Then, support member 1 is inserted in male element 2, finally, internal thread tube piece 3 is threadeded with male element 2, after being screwed, seal washer 4 is produced sealing effectiveness by the end face extruding of the end face and the male element 2 that connect end 32 of internal thread tube piece 3, screwing/extrusion process in, support member 1 can effectively prevent seal washer 4 from disadvantageous deformation (such as radial deformation, distortion etc.) occurring.
End face seal structure of the present utility model, its good sealing effect, and seal washer are not susceptible to radial deformation etc., and its degree of reliability is high, and install and use the most very convenient.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
