Abstract
A double flange transmission joint mainly comprises a main body (1), a seal ring (2), a gland (3), a flange short tube (4), a long bolt (5) and a nut (6), wherein the seal ring (2) is arranged in a clearance between the main body (1) and the gland (3), the flange short tube (4) is arranged at the lower end of the main body (1) and penetrates through the gland (3), and the long bolt (5) penetrates through the main body (1), the gland (3) and the flange short tube (4). The double flange transmission joint is characterized in that a flange is arranged at one end of the main body (1), the section of the seal ring (2) has a trapezoid structure, the long bolt (5) has full threads, and screw holes equally dividing the circumference are correspondingly arranged on the flange short tube (4). The utility model provides the novel double flange transmission joint, which has the advantages of simple structure, convenience for operation and good sealing performance.
Description
Technical field
The utility model relates to a kind of pipe coupling, refers more particularly to a kind of pair of flange force transmission joint.
Background technique
Existing pipe coupling with Telescopic has multiple structure, its sealability also respectively has quality, wherein a kind of pipe coupling commonly used, form by main body and short tube, adopt circular seal ring between the two, very easily cause seal failure in actual use because of the telescopic displacement of pipeline enclosure changes, in case and the circular seal ring ageing failure, just can't place under repair, so that cause integral body to scrap.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of novel two flange force transmission joints of simple in structure, easy to operate, good seal performance is provided.
The utility model is realized in the following way:
A kind of pair of flange force transmission joint, mainly include main body 1, seal ring 2, gland 3, flange short tube 4, stay bolt 5, nut 6, seal ring 2 is located between the gap of main body 1 and gland 3, flange short tube 4 is located at main body 1 lower end, and pass gland 3, stay bolt 5 passes main body 1, gland 3, flange short tube 4, it is characterized in that: described main body 1 one ends are provided with flange, the cross section of described seal ring 2 is a trapezium structure, described stay bolt 5 is a Full Thread FT, and main body 1, gland 3, flange short tube 4 are respectively equipped with corresponding screw by the circumference five equilibrium.
Between gland 3 and main body 1, be provided with hold-down bolt 7.
Fitting surface between main body 1, gland 3, the flange short tube 4 is ramp structure.
Flange short tube inserts in the main body, and certain displacement amount is arranged, push down seal ring by gland, make its sealing, by the Full Thread FT stay bolt flange of equipment such as flange short tube and pump, valve is fixed again, close it and become an integral body, can adjust according to on-the-spot installation dimension, when work, can be axial force transmission to whole pipe, not only can increase work efficiency, and equipment such as pump, valve are played the certain protection effect; By hold-down bolt and gland seal ring is applied suitable pressure, make trapezoidal seal ring produce distortion, make it to form certain seal pressure, realize the sealing effect of force transmission joint.
In sum, novel two flange force transmission joints of simple in structure, easy to operate, the good seal performance of the utility model.
Description of drawings
Fig. 1 the utility model structural representation;
Embodiment
Now in conjunction with the accompanying drawings, the utility model embodiment is described in detail in detail:
As shown in Figure 1, a kind of pair of flange force transmission joint, mainly include main body 1, seal ring 2, gland 3, flange short tube 4, stay bolt 5, nut 6, seal ring 2 is located between the gap of main body 1 and gland 3, flange short tube 4 is located at main body 1 lower end, and pass gland 3, stay bolt 5 passes main body 1, gland 3, flange short tube 4, it is characterized in that: described main body 1 one ends are provided with flange, the cross section of described seal ring 2 is a trapezium structure, described stay bolt 5 is a Full Thread FT, and main body 1, gland 3, flange short tube 4 are respectively equipped with corresponding screw by the circumference five equilibrium.
Between gland 3 and main body 1, be provided with hold-down bolt 7.
Fitting surface between main body 1, gland 3, the flange short tube 4 is ramp structure.
Flange short tube inserts in the main body, and certain displacement amount is arranged, push down seal ring by gland, make its sealing, by the Full Thread FT stay bolt flange of equipment such as flange short tube and pump, valve is fixed again, close it and become an integral body, can adjust according to on-the-spot installation dimension, when work, can be axial force transmission to whole pipe, not only can increase work efficiency, and equipment such as pump, valve are played the certain protection effect; By hold-down bolt and gland seal ring is applied suitable pressure, make trapezoidal seal ring produce distortion, make it to form certain seal pressure, realize the sealing effect of force transmission joint.
