Description
Technical field
The utility model relates to a kind of pipe flanges.
Background technique
The units such as metallurgy, chemical industry have a large amount of pipelines, mostly aerial to be laid with, by flanged joint between pipeline, between flange
It is sealed by gasket, since pipeline medium is varied, especially conveys the pipeline of corrosive media, be easy to be corroded rotten
It wears, when replacing gasket operation and repairing pipeline operations, flange need to be opened to replacement gasket or block up, take out blind plate.
Flange is generally pried open using crowbar at present, but very dangerous, crowbar is easy to slip, and causes clamp hand, falls down, collides
Injury, but also more people operation simultaneously is needed, long there is the time, Ren Yuanduo, intensity is big, low efficiency, the disadvantages such as more than security risk
End.Therefore, a kind of new scheme of urgent need solves the technical problem.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure is simple, design rationally,
The pipe flange of easy-to-operate.
To solve the above problems, technical solution used by the utility model is as follows:
A kind of pipe flange, including first pipe, second pipe, first flange and second flange, the first flange are set
It is placed in first pipe, second flange is set on second pipe, and the diameter of first flange is less than second flange, first method
Rubber seal is equipped between blue and second flange；Annulate lamella is also arranged in the first pipe, ring flat-plate is located at first flange
Side；It is connected between the ring flat-plate and second flange by screw rod, one end of screw rod is equipped with the stop nut positioned at ring flat-plate side,
The other end is equipped with the fastening nut positioned at second flange side, the pressure being also arranged between ring flat-plate and second flange on screw rod
Spring.
Further, the ring flat-plate is equipped with the threaded hole connecting with screw flight, and second flange is equipped with and wears for screw rod
The through-hole crossed, the inner wall of the through-hole are shiny surface.
Further, the diameter of the ring flat-plate and the diameter of second flange are identical.
Further, the first flange and second flange are bolted to connection.
Further, the natural length of the pressure spring is greater than the distance between ring flat-plate and second flange.
Compared with prior art, the utility model has the beneficial effects that: first pipe and second pipe pass through first flange
It is fixedly connected with second flange, rubber seal can reinforce the leakproofness between first flange and second flange, when the first method
After orchid is fixedly connected with second flange, spring is at confined state between ring flat-plate and second flange, will by fastening nut
Screw rod is fixed, at this point, ring flat-plate and second flange will not all be acted on by the elastic force of pressure spring, keeps two flanged joints secured；Work as needs
When separating two flanges progress operations, first fastening nut is unloaded, then the bolt in first flange and second flange is unloaded, this
The elastic force of sample pressure spring can be acted on in second flange and ring flat-plate, and second flange and ring flat-plate are just moved away from, so that the
One flange and second flange separate, and structure is simple, and flange separation is quick, and effectively, easy-to-operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In attached drawing, 1 is first pipe, and 2 be second pipe, and 3 be first flange, and 4 be second flange, and 5 be rubber seal,
6 be ring flat-plate, and 7 be screw rod, and 8 be stop nut, and 9 be fastening nut, and 10 be pressure spring, and 11 be bolt.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of pipe flange, including first pipe 1, second pipe 2, first flange 3 and second flange 4, first method
Orchid 3 is set in first pipe 1, and second flange 4 is set on second pipe 2, and first flange 3 and second flange 4 pass through bolt
11 are fixedly connected.The diameter of first flange 3 is less than second flange 4, and rubber is equipped between the first flange 3 and second flange 4
Sealing ring 5；Annulate lamella 6 is also arranged in the first pipe 1, the diameter of ring flat-plate 6 is identical as the diameter of second flange 4, and ring flat-plate 6
In the side of first flange 3；It is connected between the ring flat-plate 6 and second flange 4 by screw rod 7, one end of screw rod 7, which is equipped with, is located at ring
The stop nut 8 of 6 side of plate, the other end are equipped with the fastening nut 9 positioned at 4 side of second flange, are also arranged with and are located on screw rod 7
The natural length of pressure spring 10 between ring flat-plate 6 and second flange 4, pressure spring is greater than the distance between ring flat-plate and second flange, in this way
Pressure spring can just be compressed during installation, so as to separate two flanges under the effect of its elastic force.
Ring flat-plate 6 is equipped with the threaded hole being threadedly coupled with screw rod 7, and second flange 4 is equipped with the through-hole passed through for screw rod 7,
The inner wall of the through-hole is shiny surface, and one end of such screw rod can be fixed, and the other end can pass through through-hole and stretch out, thus
Compression press spring makes pressure spring store power.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the utility model claims
Within the scope of.
