water heater drainage system

Abstract

The invention discloses a drainage system for a water heater, which comprises a hot water pipe A, a cold water pipe, and a water mixing valve. The ends of the hot water pipe A and the cold water pipe respectively correspond to the hot water port and the cold water port of the water mixing valve in airtight and fixed communication; Including: joint pipe A, joint pipe B, hot water pipe B, air intake pipe, reversing ball block, rotating column cable, torsion spring, bearing, water distribution pipe; the inner cable connecting the cable to the mixing valve adjustment handle retracts, The inner line end connected by the cable and the rotating column is rotated and reset together with the rotating column under the action of the torsion spring. At this time, the reversing ball rotates from the position blocking the intake pipe to the position blocking the hot water pipe A. At this time, the electric water tank Hot water can no longer enter the hot water pipe A, and the outside air enters the air intake pipe to continue to press down the hot water inside the hot water pipe A, and the hot water inside the hot water pipe A is discharged from the water distribution pipe, which solves the current problem of hot water in winter. The hot water in the water pipe cannot be discharged after the water mixing valve is closed.

Description

technical field

[0001] The invention belongs to the technical field of hot water pipes, and relates to a water heater drainage system. Background technique

[0002] In the current water heater pipeline laying, since the water mixing valve is far away from the water outlet of the water heater, the hot water in the hot water pipe cannot be discharged after the water mixing valve is closed in winter. The water in the hot water pipe is released earlier, which is extremely inconvenient to use, and will cause the cold water in the cold water pipe and the hot water pipe to be wasted simultaneously. Contents of the invention

[0003] In order to solve the above technical problems, the present invention provides a water heater drainage system.

[0004] The present invention is achieved through the following technical solutions.

[0005] A drainage system for a water heater provided by the present invention comprises a hot water pipe A, a cold water pipe, and a water mixing valve,...
