Description
【Technical field】
The present invention relates to a kind of duct closing type device, and in particular to a kind of pipe end sealing device.
【Background technology】
It is known, at present, it is necessary to carry out closed-water test to no pressure pipeline in rainwater or blow-off line construction operation,
Then original no pressure pipeline closed-water test smears cement mortar, in water using the wall of brick 24 centimeters of thickness
After cement mortar solidifies and reaches sufficient intensity, Quality supervision and acceptance check department, which pass through to pour water, obtains the qualified data of closed-water test；
Composite demand is just calculated in construction after examining the tightness of pipeline to meet design requirement；This form of construction work is typically into pipeline
Add before water, it is necessary to which six to seven days in advance first in pipe ends brick and cement mortar respectively one plug of block, and will be at twice
Paint, it is water-tight to ensure；After test for added water meets the requirements, the experimental water in pipeline is drained, and plug is pounded simultaneously
Clean out, this general process at least needs seven days, and the larger pipe of caliber then needs the time of ten days or so, this side
Formula not only wastes time and energy, and very wasting manpower and material resources；Occur many pipe end sealing devices in the market, due to
Structure design it is unreasonable, easily there is seepy question during use, it is impossible to adapt to used in closed-water test.
【The content of the invention】
In order to overcome deficiency of the prior art, the invention discloses a kind of pipe end sealing device, utilizes cylinder, envelope
Pipe plugging is made cylinder be fixed on pipe end, facilitates the closed-water test to pipeline by closure plate and rubber sleeve by bolt.
In order to realize the goal of the invention, the present invention uses following technology：
A kind of pipe end sealing device, including cylinder, closure plate, annular protrusion, rubber sleeve, bolt and pipeline, in cylinder
One end is provided with closure plate, and the other end outer rim of the cylinder is provided with annular protrusion, annular groove is provided with the middle part of the outer edge surface of cylinder,
Rubber is set in the annular groove, and a plurality of protruding ring is interval with the outer edge surface of the rubber sleeve, penetrates pipe end
The a plurality of protruding ring of rubber sleeve and inner-walls of duct are interference fitted on portion's cylinder, cylinder annular groove between annular protrusion
At least three screws are distributed with cylinder in a ring, at least three bolts are through at least three screw respectively, it is described extremely
Few three bolts are withstood on the inwall of pipeline.
Described pipe end sealing device, extension diameter section is arranged in annular groove to the cylinder between annular protrusion.
Described pipe end sealing device, the extension diameter section of the cylinder and the inwall of pipeline coordinate for gap.
By adopting the above-described technical solution, the present invention has the advantages that：
Pipe end sealing device of the present invention, in use, cylinder is inserted in pipe end, annular protrusion is withstood on
Pipe end, make pipe plugging using the collective effect of cylinder, plugging plate and rubber sleeve, be then fixed on cylinder using bolt
Pipe end, can be to the closed-water test of pipeline；The present invention is simple in construction, and use cost is relatively low, can install at that time, real at that time
Test.

【Embodiment】
With reference to the following examples, the present invention can be explained in greater detail；It should however be noted that not office of the invention
It is limited to following embodiments；The open purpose of the present invention is intended to protect all changes and improvements in the scope of the invention.
With reference to the pipe end sealing device described in accompanying drawing 1,2 or 3, including cylinder 7, closure plate 6, annular protrusion 3, rubber sleeve
2nd, bolt 5 and pipeline 9, closure plate 6 is provided with the one end of cylinder 7, the other end outer rim of the cylinder 7 is provided with annular protrusion 3, in cylinder
Annular groove 10 is provided with the middle part of 7 outer edge surface, rubber sleeve 2 is arranged in the annular groove 10, the outer edge surface of the rubber sleeve 2
On be interval with a plurality of protruding ring 1, penetrate a plurality of protruding ring 1 of rubber sleeve 2 and the inwall interference of pipeline 9 in the end cylinder 7 of pipeline 9
Coordinate, be arranged to extension diameter section 8 in annular groove 10 to the cylinder 7 between annular protrusion 3, be on the extension diameter section 8 of cylinder 7
Annular spread has at least three screws 4, that is, at least three screws 4 are equidistant and are evenly distributed on extension diameter section 8, at least three
Bolt 5 is through at least three screw 4 respectively, and at least three bolt 5 is withstood on the inwall of pipeline 9, the cylinder 7
The inwall of extension diameter section 8 and pipeline 9 be gap cooperation.
Implement pipe end sealing device of the present invention, the plugging structure provided with reference to accompanying drawing 2, in use, first will
The part of bolt 5 is penetrated in screw 4, is inserted cylinder 7 in the end of pipeline 9 using annular protrusion 3, when annular protrusion 3 withstands on pipe
During 9 end of road, using spanner fastening bolt 5, force the outer end of bolt 5 to withstand on the inner wall of end of pipeline 9, then start to pipeline
Closed-water test；After the completion of experiment, bolt 5 is loosened using spanner, being respectively fitted over screwing for bolt 5 using rope holds outside
Draw, can easily remove the present invention.
Part not in the detailed description of the invention is prior art.
