Water scale removing device for water mixing valve

Abstract

The invention discloses a water scale removing device for a water mixing valve. The water scale removing device comprises the water mixing valve and water inlet pipes, and the water scale removing device is arranged on the parts, in front of the water mixing valve, of the water inlet pipes. The water scale removing device comprises a shell and a cylindrical filter screen, the shell is of a three-cavity T-shaped pipe structure, the long pipe is a vertical pipe, the short pipe is a horizontal pipe, a step table is arranged at the lower end of the inner wall of the vertical pipe, an end opening of the lower end of the inner wall of the vertical pipe is sealed, a discharging port is formed in the position, close to the bottom, of the lower end of the vertical pipe, and the discharging port is sealed through a screw and a sealing ring. The two ends of the tubular filter screen are through, the outer diameter of the tubular filter screen is matched with the diameter of the inner wall of the water inlet pipe, the tubular filter screen is arranged in the vertical pipe, the upper end of the tubular filter screen is higher than the top of the inner wall of the horizontal pipe, and the other two end openings of the shell are connected with the water inlet pipes. The water scale removing device is additionally provided with a filter device, a user can remove dirt regularly, the problem that water scale and other impurities enter a valve element of the water mixing valve, the sealing performance of the valve element is damaged, and the sensitivity of the valve element becomes invalid is solved, and the water scale removing device has the advantage that cleaning is convenient and fast.

Description

technical field [0001] The invention relates to a scale cleaning device, in particular to a scale cleaning device used for a water mixing valve in a solar hot water system, and belongs to the technical field of solar water heaters. Background technique [0002] Solar water heaters passively perform light-to-heat conversion, and cannot control the temperature in the water tank. In addition, the water quality varies greatly in various regions. Therefore, the generation of scale is inevitable. During the use of solar water heating systems in the market, solar water heaters The scale continuously flows down the pipe. If there is no filter installed there (such as figure 1 As shown), the scale will enter the spool of the mixing valve (including the thermostatic valve). After the system has been running for a period of time, the accumulation of scale will reduce the sealing performance of the ceramic spool of the mixing valve and reduce the sensitivity of temperature adjustment, ...

[0002] Solar water heaters passively perform light-to-heat conversion, and cannot control the temperature in the water tank. In addition, the water quality varies greatly in various regions. Therefore, the generation of scale is inevitable. During the use of solar water heating systems in the market, solar water heaters The scale continuously flows down the pipe

If there is no filter installed there (such as figure 1 As shown), the scale will enter the spool of the mixing valve (including the thermostatic valve). After the system has been running for a period of time, the accumulation of scale will reduce the sealing performance of the ceramic spool of the mixing valve and reduce the sensitivity of temperature adjustment, resulting in mixed water. After the valve has been used for a period of time, the failure rate is high; if a filter is added to the front end of the mixing valve, it is very inconvenient to clean, and professional personnel are required to use professional tools such as wrenches to clean it. Due to the difficulty of cleaning, many users do not clean or clean it. As a result, the water pipes are blocked, resulting in poor water flow and affecting bathing and other failures.
