Problems solved by technology

When the user returns home, there is no hot water or the amount of hot water cannot meet the user's needs, and the water needs to be refilled before heat exchange, which takes a long time
In addition, adding water to the water tank manually will cause inconvenience in using hot water because the user forgets to fill in the water

Embodiment Construction

[0029] The specific implementation of the solar water heater emptying valve of the present invention will be described below with reference to the accompanying drawings.

[0030] Such as figure 1 As shown, a solar water heater emptying valve operating device includes a solar water heater water tank 1, an emptying valve 2, a water supply solenoid valve 5, a drain valve 10, an air pipe 9, an air hose 11, and an air distribution pipe 12.

[0031] The solar water heater water tank 1 is provided with an air outlet 8.

[0032] The emptying valve includes a piston, a valve cylinder, a valve body, a connecting rod, a driving rod and a driving mechanism for the telescopic movement of the driving rod. One end of the valve cylinder is sealingly connected to the water tank of the solar water heater, and the other end is sealingly connected to the interface of the valve body, and the valve body is also provided with a water inlet and outlet.

[0033] Ventilation pipe, ventilation hose, a...

Abstract

The invention discloses a solar water heater emptying valve operating device comprising a solar water heater water tank, an emptying valve, a water feeding electromagnetic valve and a water drainage valve. The solar water heater water tank is connected to a water using device through the emptying valve and a water discharging valve to form a hot water supplying pipeline, the bottom of the hot water supplying pipeline is provided with the water drainage valve, and the hot water supplying pipeline is connected to a cold water resource through the water feeding electromagnetic valve. The device is characterized in that the emptying valve, the water feeding electromagnetic valve and the water drainage valve are connected to a controller through control lines, and the controller is provided with a emptying valve switching control module, a water feeding control module and a pipeline water drainage module; from 50 minutes to 24 hours after a user uses hot water and the emptying valve of the solar water heater is opened, the emptying valve switching control module controls the emptying valve to close once or open and close for several times automatically according to the time. The device is ingenuous and unique in design and simple in structure and is capable of removing the scale of the emptying valve automatically, the service life of the emptying valve can be prolonged effectively, automatic solar water heater water feeding can be implemented, and usage is facilitated.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a solar water heater emptying valve. Background technique [0002] The solar water heater is installed on the roof or the roof, and is connected with the user's water supply pipe through the pipeline. Since there is always water in the pipeline, and the water will not heat up, the user must put a period of cold water before using it. The water will become colder again, and users who are higher from the roof will have more cold water. Poor insulation in northern areas will cause water pipes to freeze. [0003] In order to solve the above problems, technicians designed an emptying valve to use up the hot water in the pipeline. However, the service life of the emptying valve commonly used in solar water heaters is very short, and most products are within one year. The reasons are as follows: [0004] Most users do not use the emptying valve in summer, because the water temperature of solar ...
