Abstract
The invention discloses a seal joint. The seal joint comprises a joint body with the inner diameter fitting the outer diameter of a shaft part, the joint body comprises a limiting step and a threaded section, the limiting step can be abutted against the inner side of a wall plate, the threaded section is capable of extending out of a mounting hole of the wall plate, and the threaded section of the joint body is screwed by a nut after extending out of the mounting hole on the wall plate. By means of the structure, the wall plate can be directly perforated, and one end of the joint body is limited by the limiting step while the other end of the joint body is tightly pressed on the wall plate after extending out of the mounting hole, so that no auxiliary part welding is needed for the wall plate. The seal joint is simple in structure, steps of perforating and thread tapping are avoided, welding is not needed, processing, mounting and demounting are pretty simple and convenient, and manufacturing cost is low. Further, since a seal structure which is static seal is adopted, the seal joint is high in seal reliability. In addition, the shaft part and the wall plate are not in fixed connection and capable of axially moving to a certain extent to bear axial displacement resulted from vibration and impact.
Description
Technical field
The present invention relates to a kind of for being tightly connected of wallboard and axial workpiece, specifically a kind of SEALING FITTING.
Background technique
Will be through the panel joining structure of casing for some axial workpieces in machine-building process, generally adopt traditionally welded flange on wallboard, the tapping of punching on flange again, and then axial workpiece is passed from wallboard, the last Placement sealing by seal ring again, traditional this Hermetical connecting structure, on the one hand, in manufacturing process, because the parts of needs processing are more, make its processing difficulties complexity, also very high to the required precision in hole in course of working, be difficult for processing; On the one hand, what in connection procedure, form is rigidly connected, and makes to install rear axial workpiece relative with joint part fixing in addition, can not bear vibration and impact.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, and SEALING FITTING simple and convenient and that can bear vibration and impact is installed in processing.
In order to solve the problems of the technologies described above, SEALING FITTING of the present invention, comprise the joint body that an internal diameter and axial workpiece external diameter adapt, described joint body comprises that one section of limited step that can be pressed over wallboard inner side and one section can stretch out the thread section of the mounting hole on wallboard, and the thread section of joint body is screwed by a nut after stretching out the mounting hole on wallboard.
Between described limited step and wallboard inner surface, the first O-ring seals is installed.
On the internal diameter at described joint body upper limit step place, have circular groove, circular groove is interior by the second O-ring seals is installed.
Adopt after above-mentioned structure, due to the joint body with limited step and thread section arranging, thus can be on wallboard directly perforate, joint body one end is spacing by limited step, the other end is screwed and is pressed on wallboard by a nut after stretching out mounting hole, making no longer to need to do any auxiliary component on wallboard welds, it is simple in structure, the tapping step of not punching, also without welding, processing is installed and is dismantled all very simple and convenient, low cost of manufacture, the sealing configuration simultaneously adopting is static seal, sealing reliability is high, make in addition not to be fixedly connected with between axial workpiece and wallboard, can there is certain axial float, bear some vibrations and impact the axial displacement producing.
Accompanying drawing explanation
Fig. 1 is the structural representation of SEALING FITTING of the present invention;
Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, SEALING FITTING of the present invention is described in further detail.
As shown in the figure, SEALING FITTING of the present invention, comprise the hollow joint body 1 that an internal diameter and axial workpiece adapt, when installation, can make joint body 1 be enclosed within on axial workpiece, the axial workpiece external diameter of the internal diameter of joint body 1 and demand coordinates, joint body 1 is divided into two sections, wherein one section is spacing section of can be pressed over the limited step 2 of wallboard inner side and form, other one section is the thread section 3 that can stretch out the mounting hole on wallboard, when installation, spacing section is carried out spacing with the inner side of wallboard, thread section is reached outside the mounting hole on wallboard, the thread section of joint body 1 is screwed by a nut 4 after stretching out the mounting hole on wallboard, make thus it clamp wallboard from the other side of wallboard, the first O-ring seals 5 is installed between limited step 2 and wallboard inner surface, on the internal diameter at joint body 1 upper limit step place, have circular groove, in circular groove, by the second O-ring seals 6 is installed, as can be seen here, the two circle seal rings that the first O-ring seals 5 and the second O-ring seals 6 form can play good sealing effect.
