Abstract
The invention provides a rigid connection sealing method, which comprises steps: firstly, inserting a connecting end of a first pipeline into a connecting end of a second pipeline; secondly, using a first sealing ring to surround the first pipeline and be hermetically connected with the first pipeline, wherein the first sealing ring is adjacent to the connecting end of the second pipeline, and the sum of the thickness of the first sealing ring and the outer edge radius of the first pipeline is equal to the outer edge radius of the second pipeline; thirdly, using a second sealing ring to surround the first sealing ring and the connecting end of the second pipeline and be hermetically connected with the first sealing ring and the connecting end of the second pipeline; and fourthly, arranging a shell on the second sealing ring in a surrounding manner. The rigid connection sealing method is simple in structure, high in strength, convenient in mounting, effective in sealing and convenient in sealing of pipelines of different outer diameters.
Description
Technical field
The present invention relates to being connected and encapsulating method between a kind of pipeline and the pipeline, relate in particular to a kind of encapsulating method that is rigidly connected that is applicable to the various outer diameter pipeline.
Background technique
Pipeline is connected with normal flange-type or the clamp band type of adopting of being rigidly connected of pipeline, but when the external profile diameter of two pipelines is inequality, generally can only select flange-type to connect.
It is exactly two pipelines, pipe fitting or equipment that flange connects, and is fixed on separately on the flange plate earlier, between two flange plate, adds flange gasket, with bolton together, has accomplished connection.Pipe fitting that has and equipment have carried flange plate, also are to belong to flange to connect.
This connection is mainly used in being connected of cast iron tube, line with rubber pipe, non-ferrous metal pipe and flange valve etc., and manufacturing equipment connects with also all adopting flange being connected of flange.
The main feature that flange connects is high, the good seal performance of convenient disassembly, intensity.Require the sealing surface of two flange keeping parallelisms, flange not damage during mounting flange, and will clean out.The pad that flange is used will be selected for use according to design code.Therefore, the flange connection is complicated, and working condition requirement is higher.And device cost is bigger.
Patent CN200920306596 has proposed a kind of novel seal form, mainly is through step-like carbon-steel parts of welding on outlet pipe, realizes and being connected and sealing of baffler through this step.But mainly there is following deficiency in this patent: complex structure, need be on outlet pipe the extra soldered part; If snap the welding position, can cause two pipelines to break away from.
Therefore, those skilled in the art is devoted to develop a kind of simple in structure, simple installation, has the encapsulating method that is rigidly connected of higher-strength.
Summary of the invention
In view of above-mentioned the problems of the prior art, technical problem to be solved by this invention is that the existing encapsulating method complicacy that is rigidly connected, inconvenience are installed.
A kind of encapsulating method that is rigidly connected provided by the invention may further comprise the steps:
Step 1 is inserted the connecting end of first pipeline in the connecting end of second pipeline;
Step 4 adopts housing around being located on said second seal ring.
In a preferred embodiments of the present invention, said housing, first pipeline and second pipeline are provided with screw, adopt bolt to be connected between said housing and said first pipeline and second pipeline.
In another preferred embodiments of the present invention, housing in the said step 4 and said second seal ring are tightly connected.
In another preferred embodiments of the present invention, said first seal ring and/or second seal ring are made up of elastic component.
In another preferred embodiments of the present invention, said first seal ring and/or second seal ring are provided with interface, and said interface is the concavo-convex structure that matches.
In another preferred embodiments of the present invention, said interface is the concavo-convex zigzag that matches.
In another preferred embodiments of the present invention, an end of first seal ring described in the said step 2 and an end of said second pipeline are tightly connected.
In another preferred embodiments of the present invention, the outer rim radius of said first pipeline equals the inner edge radius of second pipeline.
In another preferred embodiments of the present invention, said housing is processed by stainless steel.
The encapsulating method that is rigidly connected of the present invention is simple in structure, intensity is high, easy for installation, and good sealing effect can be easily seals the pipeline of various outer diameter.
Description of drawings
Fig. 1 is be rigidly connected embodiment's the structural representation of encapsulating method of the present invention;
Fig. 2 is the be rigidly connected structural representation of interface of seal ring of encapsulating method of the present invention;
Fig. 3 is the be rigidly connected structural representation of z font interface of seal ring of encapsulating method of the present invention.
Embodiment
Below will combine accompanying drawing that the present invention is done concrete explaination.
A kind of encapsulating method that is rigidly connected of embodiments of the invention may further comprise the steps:
As shown in fig. 1, step 1 is inserted the connecting end of first pipeline 1 in the connecting end 21 of second pipeline 2, accomplishes sealing preparatory work;
Step 4 adopts housing 5 around being located on said second seal ring 4.Housing is used for fixing and protects inner seal rings.
The present invention adopts the pipeline of staggered floor construction sealing various outer diameter, simple in structure, intensity is high, easy for installation, and good sealing effect can be easily seals the pipeline of various outer diameter.
In the encapsulating method that is rigidly connected of embodiments of the invention, can be provided with screw on housing, first pipeline and second pipeline, state and adopt bolt to be connected between housing and first pipeline and second pipeline.The mode of utilizing bolt to tighten further fix first pipeline and second pipeline and between seal ring.
As shown in fig. 1, in the encapsulating method that is rigidly connected of embodiments of the invention, the housing 5 and second seal ring 4 are tightly connected.Further enhanced leaktightness effect.
In addition, in the encapsulating method that is rigidly connected of embodiments of the invention, first seal ring 3 and/or second seal ring 4 are made up of elastic component.Elastic component has elasticity, has better sealing function.
As shown in Figure 2, in the encapsulating method that is rigidly connected of embodiments of the invention, first seal ring 3 and/or second seal ring 4 are provided with interface, and interface is the concavo-convex structure that matches.Both convenient installation of the concavo-convex chimeric mutually structure that matches has better sealing effect again.Wherein, as shown in Figure 3, preferable interface is the concavo-convex zigzag that matches.
