SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide a building engineering steel pipe connector, can realize "take water" operation, work efficiency increases substantially.
The utility model is realized by the following technical proposal, and provides a constructional engineering steel pipe connector which comprises a diversion transition pipe and a water inlet sleeve which is connected with one end of the diversion transition pipe and has an inner diameter larger than that of the diversion transition pipe; a sealing washer is arranged at the joint of the diversion transition pipe and the water inlet sleeve; the other end of water conservancy diversion transition pipe is connected out the water connecting piece, the sleeve pipe of intaking can overlap in former pipeline outside and can weld with former pipeline, it is the connecting pipe of taking the screwed connecting pipe or installing the flange to go out the water connecting piece.
Preferably, the inner diameter of the water inlet sleeve is larger than the outer diameter of the original pipeline.
Preferably, the inner diameter of the diversion transition pipe is equal to the inner diameter of the original pipeline.
Preferably, the sealing gasket is a fire-resistant sealing gasket.
Preferably, the outer diameter of the sealing washer is the same as the inner diameter of the water inlet sleeve.
Preferably, the inner diameter of the sealing washer is the same as the inner diameter of the flow guiding transition pipe.
The utility model has the advantages that:
1. the utility model has simple structure, simple assembly and installation, and convenient batch processing and production;
2. the construction is convenient, the operation can be carried out with water only by welding the pipe joint with the outer surface of the original pipeline and then butting the pipe joint with other finished pipe fittings on site, and the working efficiency is greatly improved;
3. the welding operation part is 'waterless' connection operation, the operation is convenient, and the construction difficulty is reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic sectional view taken along line A-A of FIG. 1;
shown in the figure:
1. the water-saving pipeline comprises a diversion transition pipe 2, a water inlet sleeve 3, a sealing washer 4, a water outlet connecting piece 5 and an original pipeline.
Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1 and 2, the utility model comprises a diversion transition pipe 1 and a water inlet sleeve 2 connected with one end of the diversion transition pipe 1 and having an inner diameter larger than the diversion transition pipe 1. And a sealing washer 3 is arranged at the joint of the diversion transition pipe 1 and the water inlet sleeve 2. The other end of water conservancy diversion transition pipe 1 is connected out water connecting piece 4, water connecting piece 4 is the connecting pipe of taking the screw thread or installing the connecting pipe of flange, realizes through water connecting piece 4 that dock with follow-up pipeline convenient and reliable. The connecting pipe with the threads is provided with general conventional threads so as to be connected with subsequent pipe fittings such as straight sections and valves, and the connecting pipe provided with the flange is provided with a general conventional flange so as to be connected with subsequent pipe fittings such as flanges and valves.
The inner diameter of the water inlet sleeve 2 is larger than the outer diameter of the original pipeline 5, the inner diameter of the diversion transition pipe 1 is equal to the inner diameter of the original pipeline 5, and the water inlet sleeve 2 can be sleeved outside the original pipeline 5 and can be welded with the original pipeline 5. During construction, the water inlet sleeve 2 is sleeved outside the original pipeline 5, the water inlet sleeve 2 is welded with the original pipeline 5, and the sealing gasket 3 is extruded together at the connecting part of the end part of the original pipeline 5 sleeved in the water inlet sleeve 2, the diversion transition pipe 1 and the water inlet sleeve 2, so that the sealing effect is enhanced, water backflow to the water inlet sleeve 2 is avoided, and the welding seam quality defect caused by the construction difficulty during welding of the water inlet sleeve 2 and the original steel pipeline is avoided.
The sealing washer 3 is a fire-resistant sealing washer, in particular a ceramic fiber sealing washer. In the embodiment, for better sealing effect, the outer diameter of the sealing washer 3 is the same as the inner diameter of the water inlet sleeve 2, and the inner diameter of the sealing washer 3 is the same as the inner diameter of the diversion transition pipe 1.
The water flow of the original steel pipeline enters the diversion transition pipe 1 through the water inlet sleeve 2 and flows out through the water outlet connecting piece 4. The existence of the sealing washer 3 can not lead the sealing washer to flow back to the water inlet steel sleeve, thus realizing the waterless welding operation.
The utility model has simple structure, simple assembly and installation, and convenient batch processing and production; the construction is convenient, the operation can be carried out with water only by welding the pipeline on the site with the outer surface of the original pipeline 5 and then butting the pipeline with other finished pipe fittings, and the working efficiency is greatly improved; the welding operation part is 'waterless' connection operation, and the operation is convenient.
