Abstract
The improved flange comprises flange, bolt outside the flange as well as sealing gasket with outside refraining ring, spacer, and wedge between the spacer and the flange inside the flange. It features its limiting pillar inside the sealing gasket. The present invention has the features of good connecting property, simple structure and utility.
Description
The present invention relates to flange, does not particularly have screw thread, the not improvement of welded flange structure.
Present no screw thread, the welded flange main structure is not to be provided with sealing gasket in the flange plate, be on the joint of pipe fitting, to place sealing gasket during use, by flange plate sealing gasket is closely wrapped on the pipe joint, not only sealed the joint of pipe fitting, and pipe fitting is had certain join strength.But the shortcoming of this structure is only can pass through the sealing gasket application of force with the pipe fitting join strength, and sealing gasket is flexible materials such as rubber, and the connection power that is therefore applied by sealing gasket is very limited, often do not satisfy join strength needs, influenced the quality of engineering.
Purpose of the present invention is exactly at the problems referred to above, and a kind of the have no screw thread of fine join strength, welded flange not are provided.
The object of the present invention is achieved like this: the present invention includes flange plate, flange plate is outward a bolt, is sealing gasket in the flange plate, and sealing gasket has ring washer, dottle pin outward respectively, is drift between dottle pin and the flange plate, and its structure outline is to be provided with limited post in the sealing gasket.
Major advantage of the present invention:
1. join strength is good:
Owing to be provided with limited post in the sealing gasket, reach the size of setting at sealing gasket after, limited post just can contact, limit sealing gasket and no longer be compressed with dottle pin, pass through flange plate, drift this moment to the pipe fitting application of force, has promptly fully guaranteed join strength;
2. simple in structure being suitable for:
The present invention is keeping existing no screw thread, not on the welded flange architecture basics, is only increasing the limited post part, and it is simple in structure, and preparation process is also extremely simple, is easy to popularize.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of sealing gasket of the present invention and relative section;
Fig. 3 is the plan view of Fig. 2;
Fig. 4 is user mode figure of the present invention.
Below in conjunction with accompanying drawing concrete structure of the present invention is described further:
The present invention includes flange plate 2, is bolt 1 outside the flange plate 2, is sealing gasket 6 in the flange plate 2, has ring washer 8, dottle pin 5 respectively outside the sealing gasket 6, is drift 4 between dottle pin 5 and the flange plate 2, is provided with limited post 7 in the sealing gasket 6.
During use, the present invention is placed pipe fitting joint 3 places, then with 1 pair of sealing gasket 6 application of force of bolt, when sealing gasket 6 reach set reduced size after, again to bolt 1 application of force, just can increase the join strength of pipe fitting joint 3, can stop bolt 1 application of force after reaching requirement.
Claims (3)
1. do not have screw thread, welded flange does not comprise flange plate 2, flange plate 2 is outer be bolt 1, is sealing gasket 6 in the flange plate 2, sealing gasket 6 has ring washer 8, dottle pin 5 respectively outward, is drift 4 between dottle pin 5 and the flange plate 2, it is characterized in that being provided with in the sealing gasket 6 limited post 7.
2. no screw thread according to claim 1, welded flange not is characterized in that limited post 7 is for being symmetrically distributed.
3. no screw thread according to claim 1, welded flange not is characterized in that limited post 7 is cylindrical body.
