Water circulation system for vacuum setting machine

Abstract

The invention provides a water circulation system for a vacuum setting machine and belongs to the technical field of pipe setting equipment. The technical problems of existing setting machines are low in water circulation efficiency, large in energy consumption and poor in pipe cooling effect are solved. The water circulation system for the vacuum setting machine comprises a box, a spraying assembly, a water supply assembly, a water feeding assembly and a water draining assembly, wherein the water feeding assembly communicates with the water supply assembly and feeds water to the water supply assembly for centralization; the water feeding assembly feeds water to the water supply assembly, and the water circulates among the water supply assembly, the spraying assembly and the box; when the water temperature of the water supply assembly reaches a preset value, part of water can be discharged through the water draining assembly; when the water temperature of the water supply assembly reaches the preset temperature value, part of high-temperature water is discharged through the water draining assembly, and cooling water feeding and high-temperature water draining are carried out simultaneously, so that the pipe cooling effect is good, water resources are effectively saved, energy consumption is small, and the use cost is controlled.

Description

technical field [0001] The invention belongs to the technical field of pipe shaping equipment, and relates to a water circulation system, in particular to a water circulation system for a vacuum shaping machine. Background technique [0002] The vacuum setting machine is a special equipment for cooling and shaping the pipe. Its purpose is to provide a vacuum environment for the formed high-temperature pipe, and cool down and shape the pipe in the vacuum environment to make the pipe into a fixed shape. [0003] In the existing sizing machine, a nozzle is generally installed in the body of the sizing machine, and a water source is installed outside the box. The water source and the nozzle are connected through a water inlet pipe, and the bottom of the box communicates with the outside. Cool down the high-temperature pipes in the box, and the cooling water will heat up into high-temperature water and flow out from the bottom of the box. Due to the large temperature difference b...

Problems solved by technology

[0003] In the existing sizing machine, a nozzle is generally installed in the body of the sizing machine, and a water source is installed outside the box. The water source and the nozzle are connected through a water inlet pipe, and the bottom of the box communicates with the outside. Cool down the high-temperature pipes in the box, and the cooling water will heat up into high-temperature water and flow out from the bottom of the box. Due to the large temperature difference between the water flowing into and out of the shaping machine, it is impossible to quickly form a circulating water circuit. The traditional solution is Continuously drain high-temperature water and continuously supply a large amount of cooling water, and then cool the received high-temperature water into cooling water through the cooling device and put it into use again, thus forming an indirect circulating waterway, but this method has the following technical problems: 1. Serious Waste of water resources, high energy consumption, and high cost of use; 2. This indirect circulating waterway takes a long time for a single water cycle, and the water cooling efficiency is low, resulting in the inability of the pipe to be fully and timely cooled
