Hydraulic remote control exhaust valve

Abstract

The invention provides a hydraulic remote control exhaust valve, and particularly relates to a control valve used on a solar water heater. The hydraulic remote control exhaust valve consists of a left control mechanism and a right control mechanism, and any power supply or electronic product is not used; and the open and closure of the hydraulic remote control exhaust valve is controlled by use of a multifunctional water mixing valve, water inlet and outlet pipes and a remote control pipe. Through the cooperation with the multifunctional water mixing valve, the hydraulic remote control exhaust valve achieves the functions of water mixing for adjusting the temperature, automatic closing, automatic exhaust, and hot water outputting as soon as the valve is opened. The hydraulic remote control exhaust valve can be used for overcoming the defects that the existing control products cannot work without electric sources, pipelines has high possibility of being subjected to frost cracking in winter, and hot water existing in a water tank cannot be used; and the water run out, heat waiting and hibernation problems of the solar water heater are well solved.

Description

technical field [0001] The invention relates to an emptying valve used on a solar water heater, in particular to a hydraulic remote control emptying valve. Background technique [0002] At present, the use of solar water heaters has become very common, which can make full use of the energy of solar energy, and thus save a lot of energy. Combination of antifreeze, float switch and other products with mixing valve, most of these combinations use power supply. Wires need to be laid indoors and outdoors. Due to working in a humid environment, the performance is very unreliable, the cost is high, and there are serious safety hazards. There are some problems in the use of solar water heaters: 1. Since the solar water outlet pipe is from the top floor of the building to the user's home, the water in this section of the pipe cannot be drained, and the exposed pipes in winter are easy to freeze and crack; 2. Due to the solar energy The water heater uses the same water pipe for wate...

Problems solved by technology

Wires need to be laid indoors and outdoors. Due to working in a humid environment, the performance is very unreliable, the cost is high, and there are serious safety hazards

There are some problems in the use of solar water heaters: 1. Since the solar water outlet pipe is from the top floor of the building to the user's home, the water in this section of the pipe cannot be drained, and the exposed pipes in winter are easy to freeze and crack; 2. Due to the solar energy The water heater uses the same water pipe for water injection and discharge. There is cold water accumulated in the pipe. Before using hot water, the cold water in the pipe must be released before normal use, resulting in unnecessary waste of water resources; Forgot to close the valve and went out, causing a lot of tap water loss

These problems have not been well resolved so far, in a sense, limiting the popularization and use of solar water heaters
