A drain valve that is easy to clean and its application method

Abstract

The invention discloses an easy-to-clean drain valve and a method for using the same, belonging to the field of drain valves. On-line cleaning of the filter is realized by adding a color-changing cleaner on the basis of the existing drain valve, which is not only convenient and quick to operate, but also It can effectively reduce the failure rate in the production process. The interior of the color-changing cleaner is provided with a settling tank next to the filter, so that the trapped impurities fall into the settling tank, which is convenient for centralized discharge. A centrifugal cleaning bowl is set in the center to catch the impurities, and the centrifugal cleaning bowl is lowered by the weight of the impurities, so that the reflective color film shrinks, so as to give the inspection personnel a signal that needs to be cleaned in time, and only need to move up and down when cleaning And rotating the centrifugal cleaning bowl can remove the impurities accumulated on it, and can realize the cleaning of the filter at the same time. It needs to be shut down, disassembled and cleaned. Compared with the prior art, it can effectively protect the structure in the valve and reduce the failure rate.

Description

technical field [0001] The invention relates to the field of steam traps, more specifically, to a steam trap that is easy to clean and a method for using the same. Background technique [0002] Steam traps are called steam traps, also called automatic drains or condensate drains, which are divided into steam system use and gas system use. The steam trap is installed at the end of the steam-heated pipeline, and its function is to continuously discharge the condensed water in the steam-heated pipeline to the outside of the pipeline. Steam traps can be divided into three types: mechanical type, thermostatic type, and thermodynamic type according to different working principles. Mechanical traps include free float type, free semi-float type, lever float type, inverted bucket type, etc. , the most ideal free floating ball heating equipment in the production process. [0003] The structure of the free-floating ball trap is simple. There is only one movable part inside, a finely ...

AI Technical Summary

Problems solved by technology

The most common failure of the free float ball trap is that the filter is blocked by impurities and dirt, and the water cannot flow into the trap. Most of the current treatment methods are to clean the pipeline, filter and dirt in the valve. In this case, not only the shutdown is required, but also the cleaning time consuming
