Description

TECHNICAL FIELD

[0001] The patent belongs to the technical field of engineering installation, and particularly relates to a cooling water pipeline and sealing of the cooling water pipeline in special equipment engineering construction. BACKGROUND

[0002] In engineering construction, the cooling water pipeline provides cooling effect for special equipment, and the quantity of the cooling water pipeline required by the engineering is large, and the work load is large. The installation speed of the cooling water pipeline directly affects the construction progress. Before the cooling water pipeline is connected to the special equipment, pipeline pressure test, sealing test and flushing need to be carried out. In order to realize the pipeline pressure test, sealing test and flushing, temporary plugging needs to be carried out on the pipe joint seat interface with a quantity of more than 100,000.

[0003] Φ8mm cooling water pipeline manufacturing is one of the important work in engineering construction, which provides guarantee for stable operation of the subsequent special equipment. There are strict technical index requirements for it: the pipeline cannot have a pit collapse phenomenon and needs to use a Φ4mm ball for each pipeline for ball passage test detection; pipeline pressure test, sealing test and flushing need to be carried out before installation, and the pipeline sealing place needs to bear 4MP water pressure. Any one of the above unqualified will cause the special equipment to "explode", causing serious economic loss.

[0004] The original cooling water pipeline and plugging device have many deficiencies, such as:

[0005] (1) Each pipeline is manually baked, and the shape, angle and size are not uniform, which increases the pipeline scrap rate by 2 times.

[0006] (2) Manual baking leads to unqualified angle and inaccurate baking size, which cannot be installed on the special equipment, causing rework phenomenon.

[0007] (3) After pipeline pressure test, sealing test and flushing, the gasket of the pipe joint seat needs to be pried out, and then the ф8mm cooling water pipeline is installed, which is complicated and time-consuming.

[0008] (4) After pipeline pressure test, sealing test and flushing, the gasket left in the pipe joint seat needs to be taken out, and there are more than 100,000 places in the whole project that need to be temporarily plugged. The gasket clamping rate is as high as 80%, at this time, ф2mm iron wire needs to be baked into a small hook to take out the gasket, which wastes a lot of labor.

[0009] (5) When the small hook is used to take out the gasket, the gasket may also be damaged, and the damage rate is 5%, which causes waste of cost; the damaged gasket is more difficult to clean, and more man-hours are needed to clean it, which needs a lot of labor.

[0010] (6) In addition, a small amount of damaged gaskets are poked into the pipeline system, which has an adverse effect on the heat exchange of the cooling water system.

[0011] (7) The work of making the pipeline and taking out the gasket wastes a lot of time, and affects the progress of the whole project. SUMMARY

[0012] The application aims to provide a cooling water pipeline and plugging device to meet the large number of cooling water pipeline manufacturing in engineering and realize pipeline installation.

[0013] The technical scheme of the application comprises a cooling water pipeline and plugging device, which comprises a cooling water pipeline and a temporary plugging device.

[0014] The temporary plugging device comprises a pipe socket, a gasket and a plugging nut, the gasket is installed on the plugging nut and connected with the pipe socket through threads.

[0015] A steel washer, a nut and a rubber gasket are sleeved on the other end of the pipeline, and the pipeline is connected with a section water pipe through the steel washer, the nut and the rubber gasket.

[0016] During work, the cooling water in the section water pipeline flows into the cooling water pipeline and then flows to the main equipment to cool the main equipment.

[0017] The pipeline is flared, flanged and bent according to the design angle and size.

[0018] The pipeline is connected with the main equipment through the flange, the second steel washer and the second rubber gasket.

[0019] The gasket is made of polytetrafluoroethylene, the outer diameter of the gasket is 1mm smaller than the outer diameter of the pipe socket, the inner diameter of the gasket is 2mm larger than the outer diameter of the plugging nut, and the thickness of the gasket is 2mm.

[0020] The sealing mode of the gasket is exposed sealing.

[0021] The pipeline is a Φ8mm pipeline.

[0022] A self-made cooling water pipeline and temporary plugging device are provided, and the pipeline is made of the following materials: a Φ8 pipeline, two steel washers, two rubber washers, one flange and one nut. The temporary plugging device is made by first increasing the outer diameter of the pipe socket, increasing the area of the upper surface of the pipe socket and improving the smoothness to make it a sealing surface. Then, the gasket is replaced with a material made of polytetrafluoroethylene, the outer diameter of which is 1mm smaller than the outer diameter of the pipe socket, the inner diameter of which is 2mm larger than the outer diameter of the plugging nut, and the thickness of which is increased to 2mm. At the same time, the thread length of the plugging nut is designed to be 7mm to save labor during installation. Finally, the sealing mode is changed from the original embedded sealing of the gasket to the exposed sealing of the gasket.

[0023] The improved system meets the needs of a large number of Φ8mm cooling water pipes required for production and installation. A temporary sealing device is designed to fit the gasket over the plugging nut, screw it into the pipe socket by hand, and then tighten it with an M18 wrench. This operation can be completed by one person. This system meets the needs of a large number of Φ8mm cooling water pipes required for temporary sealing, ensuring easy installation and quick removal.

[0024] The beneficial effects of the present invention are as follows:

[0025] (1) Only one person is required to operate the motor water inlet pipe of the entire cooling water pipeline.

[0026] (2) It can meet the needs of all cooling water pipelines and the overall structure is simple.

[0027] (3) The installation and removal of the plugging device can be completed in just 30 seconds, reducing working time.

[0028] (5) The liner of the sealing device will not enter the water system, and the system exchange operation is more secure.

[0029] (6) This method does not require any other tooling, which reduces installation and removal time and saves labor and tooling costs. BRIEF DESCRIPTION OF THE DRAWINGS
