Description

A pipe quick-connect device

【Technical field】

The invention relates to a quick connector for a pipeline, in particular to a quick connector for a pipeline.

【Background technique】

As is well known, a pipeline is a device connected by pipes, pipe couplings and valves to transport gas, liquid or fluid with solid particles. Usually, the solution used for the butt joint of larger pipes is: one end of the pipe is made as a sleeve with an enlarged diameter, and the end of the other pipe is inserted into the sleeve, but for new metal-plastic composite pipes, this The solution is not suitable, especially for pipes of the same diameter. Since the plastic composite pipe is relatively soft, when connecting, use a sleeve to "short the diameter larger than the composite pipe and make it softer", which is prone to cracking and leakage at the joint.

【Content of invention】

In order to overcome the deficiencies in the background technology, the present invention discloses a quick-connecting device for pipes. The present invention uses weather-resistant sealant and bolts to lock the pipes A and B at both ends of the quick-connecting casing, effectively avoiding the existing butt joints. The method is prone to the disadvantages of cracking and leakage at the butt joint.

In order to realize the above-mentioned purpose of the invention, the present invention adopts following technical scheme:

A pipeline quick-connect device, comprising a pipeline A, bolts, a quick-connect sleeve and a pipeline B, the middle of the quick-connect sleeve is provided with a through hole, and the two ends of the quick-connect sleeve are respectively provided with an outer ring and an inner ring , in which a plurality of screw holes are arranged at intervals on the outer ring; weather-resistant sealant is applied to the annular depression between the outer ring and the inner sleeve at both ends of the quick-connect sleeve and the annular depression at the other end, respectively, and the pipe A and the pipe B is respectively inserted into the annular depression and the other end annular depression, and a plurality of bolts pass through the screw holes to lock the pipeline A and the pipeline B respectively in the annular depression and the other end annular depression.

In the quick-connecting device for pipelines, the outer ends of the inner collars at both ends of the quick-connecting sleeve are respectively provided with slightly thinner and middle inclined-plane plug joints.

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect:

The pipeline quick-connect device of the present invention utilizes the annular depressions at both ends of the quick-connect sleeve and the annular depression at the other end, so that the inserted pipeline A and pipeline B are subjected to the action of weather-resistant sealant and bolts to form a firm connection, effectively avoiding The drawback of the existing docking method that is prone to cracking and leakage at the docking place is eliminated.

In the figure: 1. Screw hole; 2. Annular depression; 3. Inclined surface; 4. Via hole; 5. Annular depression at the other end; 6. Outer ring; Pipe B; 10, bolts; 11, inner collar.

【Detailed ways】

The present invention can be explained in more detail by the following examples, the present invention is not limited to the following examples, the purpose of disclosing the present invention is intended to protect all changes and improvements within the scope of the present invention;

In conjunction with the pipeline quick-connect device described in accompanying drawing 1 or 2, comprise pipeline A8, bolt 10, quick-connect sleeve 7 and pipeline B9, described quick-connect sleeve 7 middle part is provided with via hole 4, in quick-connect sleeve The two ends of 7 are respectively provided with an outer collar 6 and an inner collar 11, and the outer ends of the inner collar 11 at both ends of the quick-connect sleeve 7 are respectively provided with a slightly thinner and middle inclined plane 3 plug joints, wherein the outer collar 6 is spaced A plurality of screw holes 1 are provided; the annular depression 2 between the outer collar 6 and the inner collar 11 at both ends of the quick-connect sleeve 7 and the annular depression 5 at the other end are respectively coated with weather-resistant sealant, the pipe A8 and the pipe B9 is respectively inserted into the annular depression 2 and the other end annular depression 5, and a plurality of bolts 10 pass through the screw hole 1 to lock the pipe A8 and the pipe B9 respectively in the annular depression 2 and the other end annular depression 5 .

To implement the pipeline quick-connect device of the present invention, the pipeline A8 and the pipeline B9 are respectively inserted into the annular depression 2 with weather-resistant sealant and the annular depression 5 at the other end, and the annular depressions 2 and 5 at both ends of the quick-connect sleeve 7 are used The annular depression 5 at the other end forms the positioning of the pipes A8 and B9, and the bolts 10 are used to fix the pipes A8 and B9 to form a firm connection, which effectively avoids the disadvantages of cracking and leakage at the joints that are prone to occur in the existing docking methods.

The unspecified parts of the present invention are prior art.
