Abstract
The utility model discloses a seal ring for the movable joint of a duct which has the advantages of simple structure, convenient manufacture and good tightness. The utility model can be used to match with ducts of various standards.
Description
The utility model relates to a kind of improved Pipe moveable joint head seal ring, particularly a kind of Pipe moveable joint head seal ring simple in structure, easy to make.
Existing Pipe moveable joint head seal ring is flat pattern asbestos or the rubber seal ring of cutting out at the scene by different size, perhaps twine lopping and use seal ring as with oakum, raw meal belt, the expense of taking a lot of work during use material, by adorning the situation that the run, drip, leak of Oil, Water, Gas often appear in the back pipe coupling, sealing is relatively poor.
The purpose of this utility model is that a kind of simple in structure, manufacturing, easy to use will be provided, the Pipe moveable joint head seal ring of good seal performance.
Task of the present utility model is finished as follows, upper surface medial and lateral and lower surface medial and lateral at traditional flat pattern rubber seal ring respectively add a convex circle that highly equates, the total thickness of seal ring is 4～6 times of convex circle height, adopt rubber material with special mould once-through, can produce the Pipe moveable joint head seal ring of different size in enormous quantities.
Advantage of the present utility model is simple in structure, and is easy to make, and good seal performance selects by pipeline specifications that supporting seal ring saves time, material-saving for use.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the plan view of seal ring.
Fig. 2 is a～a sectional view of seal ring.
With reference to Fig. 2, (1) is the convex circle of upper surface medial and lateral and lower surface medial and lateral, and seal ring total thickness H is 4～6 times of convex circle height h.Select rubber material for use, the mold pressing once-through.Select supporting Pipe moveable joint head seal ring for use by pipeline specifications during use.
Claims (2)
1, a kind of Pipe moveable joint head seal ring made from rubber is characterized in that respectively there is a convex circle (1) that highly equates seal ring upper surface medial and lateral and lower surface medial and lateral.
2, seal ring according to claim 1, the total thickness H that it is characterized in that seal ring are 4～6 times of convex circle height h.
