Description

Infusion device for water delivery and distribution pipe

Technical Field

The utility model relates to the technical field of water pipe detection, in particular to a water conveying and distributing pipe soaking device.

Background

According to GB/T17219 sanitary safety evaluation standards of domestic drinking water equipment and protective materials and sanitary safety product inspection regulations (2001 edition) related to drinking water, the protective materials and the water treatment materials should meet corresponding sanitary safety standards, and the protective materials, the water treatment materials and accessories thereof should not pollute the water quality when the water equipment is arranged in contact with the domestic drinking water. The water delivery pipes belong to the category of water delivery and distribution equipment, and the sanitary safety of the water delivery and distribution pipes must be checked and evaluated by a checking mechanism before the water delivery and distribution pipes are marketed. The detection and evaluation of the water delivery and distribution pipe are based on the determination of the dissolved matter of the material soaking liquid, soaking water is introduced into the water pipe, the harmful substances dissolved out of the inner pipe wall are soaked to be dissolved into the soaking liquid, and then the safety of the water delivery and distribution pipe is evaluated by determining the content of the harmful substances in the soaking liquid.

The water delivery and distribution pipe is mainly made of stainless steel pipes, galvanized pipes, cast iron pipes, PVC pipes, PU pipes and the like. Most of the water delivery and distribution pipes have an inner diameter of 1cm-15cm and a delivery length of 1m-1.5m. The existing pretreatment method is mostly manual treatment, and comprises the steps of firstly, fully flushing the inner wall of a water pipe to be tested by using pure water by an experimenter, then plugging a waterproof plug on one end of the water pipe to be tested, filling soaking water into the pipe to be tested, and pouring out the soaking water after soaking for 24 hours. In practice, this process has mainly the following problems: (1) When an experimenter manually washes a water pipe to be tested, the experimenter needs to operate and observe the water pipe at the side, the washing time and the washing degree are difficult to control, the washing effect is uncontrollable, the subsequent dissolution of harmful substances in soaking is unstable, and the result is unstable; (2) Slow water leakage can occur when an experimenter plugs the bottom of a water pipe to be tested with a waterproof plug, and after 24 hours, the water leakage is caused by soaking in the water pipe to be tested, so that the experiment fails; (3) The whole pretreatment process needs to consume a large amount of manpower, and the sample to be tested needs to be completed by 2-3 people when the sample to be tested is complex or more, so that the efficiency is low. In addition, in the actual work of wading product inspection detection mechanism, the water delivery pipe sample accounts for the water delivery equipment sample of delivery one third and more, accounts for higher. Therefore, the soaking device for treating the water delivery and distribution pipe can effectively solve the three problems, improves the accuracy and the efficiency of pretreatment and has practical significance
