Water distributor and production process thereof

Abstract

The invention belongs to the technical field of pipeline connection pieces, and particularly provides a water distributor and a production process thereof. The water distributor comprises a main pipe and a plurality of branch pipes correspondingly communicated with the main pipe; one end of the main pipe is a water inlet end, and an end socket is arranged at the other end of the main pipe; and the water inlet end is subjected to necking down treatment, and the inner diameter of the water inlet end is made to be shrunk by 30-40%. By means of the water distributor, the water hammer effect in the water distributor can be effectively reduced, and water flow is uniformly and stably distributed in the water distributor. The production process of the water distributor has the beneficial effects of being high in automation degree and high in production efficiency; and arc holes and arc concaves which are precisely matched can also be obtained through an arc punching machine and a punching device by means of a numerical control technology, seamless butt joint of the arc holes and the arc concaves is achieved, and the sealing performance and the attractiveness of an obtained product are improved. In the welding step, the relative positions of the main pipe and the branch pipes are fixed by means of point welding of three points, then, the main pipe and the branch pipes are completely welded and sealed through hoop welding, positioning can be facilitated by performing point welding firstly, and it is prevented that the branch pipes deflect in the hoop welding process.

Description

technical field [0001] The invention relates to the technical field of pipe connectors, in particular to a water separator and a production process thereof. Background technique [0002] The water separator is a water system, which is used to connect various heating pipes for distribution and return of water, and a water collection device. The first generation of water distributors used silk joints to connect and assemble the main pipes and branch pipes. The seal was not tight, and water leakage occurred frequently. The second-generation water separator has many welding points, and the end needs to be manually added with fixed caps and small heads during the practical process, which is inconvenient to use. [0003] Most of the main pipes of existing water distributors are straight through pipes with uniform diameters. The water inlet end of this straight pipe is consistent with the inner diameter of the main body of the main pipe, so that the water flow speed will not decre...

AI Technical Summary

Problems solved by technology

The first-generation water separators are connected and assembled by connecting the main pipes and branch pipes with wire joints. The seal is not tight, and water leakage and seepage occur frequently.

The second-generation water separator has more welding points, and the end needs to be manually added with fixed caps and size heads during the practical process, which is inconvenient to use

[0004] In addition, when the existing water separator is installed and used, it is necessary to additionally set up the plugging and re-open the vent hole for exhaust and pressure relief, which brings great inconvenience to the use

[0005] In addition, the existing production process of the water separator has the disadvantages of low degree of automation, low production efficiency, tight fit between the main pipe and the branch pipe, many welding points, poor product aesthetics, poor anti-corrosion and anti-corrosion performance of the product, etc.
