Balance water mixing valve with emptying device embedding in valve body and hot water system with same

Abstract

The invention discloses a balance water mixing valve with an emptying device embedding in a valve body and a hot water system with the balance water mixing valve. The balance water mixing valve comprises a movable valve sheet and a fixed valve sheet, wherein a first cold water inlet, a second cold water inlet, a cold water outlet, a hot water inlet and a mixed water outlet are formed in the fixed valve sheet, a control device drives the movable valve sheet to motion, the first cold water inlet and the cold water outlet are communicated or disconnected, and the hot water inlet, the second cold water inlet and the mixed water outlet are synchronously communicated or disconnected. When a valve is closed, emptying can be automatically or semi-automatically conducted through the emptying device. According to the hot water system with the balance water mixing valve, cold water flows into the bottom of a thermal storage water tank, and an equal amount of hot water flows out of the upper portion of the thermal storage water tank, so that the actual amount of stored water of the thermal storage water tank is in dynamic equilibrium, low-pressure water ejecting and water discharging can be achieved in the hot water system, the pressure of the thermal storage water tank and a pipeline can be relieved, the phenomenon of 'water hammer' can be further eliminated, the hot water system is prevented from being impacted by the 'water hammer'. Due to the fact that swelling, splitting, water leakage or deformation can not occur, the service life of the thermal storage water tank and the service life of a pipe fitting can be effectively prolonged.

Description

technical field [0001] The present invention relates to the technical field of plumbing pipe fittings, more specifically, to a balanced water mixing valve embedded with an emptying device on the valve body, and also relates to a balanced water mixing valve embedded with the emptying device on the valve body hot water system. Background technique [0002] Traditional hot water systems used to provide hot water to users such as figure 1 As shown, the first cold water inlet pipeline 39 that adds cold water to the hot water storage tank 41 and the second cold water inlet pipeline 44 that provides cold water mixed with the hot water in the hot water outlet pipeline 40 of the hot water storage tank 41 are Separately installed, a water inlet valve 43 is provided on the first cold water inlet pipeline 39, cold water flows into the hot water storage tank 41 through the first cold water inlet pipeline 39, and when the hot water storage tank 41 is filled with water, it is closed The ...

AI Technical Summary

Problems solved by technology

As the user continues to use the water in the hot water storage tank 41, after the water in the hot water storage tank 41 is used up, the water inlet valve 43 on the first cold water inlet pipeline 39 in the hot water storage tank 41 needs to be opened again , at this time, cold water enters the hot water storage tank 41 through the first cold water inlet pipeline 39. During this process, since the water inlet valve 43 is often opened and closed, the phenomenon of "water hammer" is prone to occur, that is, the cold water enters the heat storage tank. The water tank 41 will produce impact force on the hot water storage tank 41 and the pipe fittings, causing the hot water storage tank 41 and the pipe fittings to deform or burst, and the pipeline is prone to the phenomenon of "running, dripping and leaking". The hot water storage tank 41 and the pipe fittings The service life is short, it needs to be manufactured with thicker steel plates, and the maintenance cost is high

Secondly, the cold water inlet 42 connected to the first cold water inlet pipeline 39 is arranged at one end of the bottom of the hot water storage tank 41, and the hot water outlet 38 of the hot water storage tank 41 is arranged at the bottom of the other end of the hot water storage tank 41, so that After closing the hot water and cold water mixing valve 45, the hot water outlet pipeline 40 cannot be emptied, and the next time you need to wait for a period of time to drain the cold water in the hot water outlet pipeline 40 of the hot water storage tank before using it. Hot water and the first cold water inlet pipeline 39 cannot be emptied, which is inconvenient to use, especially in cold weather seasons or regions. The water in the water inlet pipe 39 will freeze, which will lead to serious consequences that the hot water outlet pipe 40 of the hot water storage tank 41 cannot discharge water or the first cold water inlet pipe 39 cannot enter water, which seriously affects the use efficiency of the equipment
