Problems solved by technology

However, in the existing emptying methods, some emptying valves are installed sideways in the insulation layer on the right side of the water heater tank. Although it can protect the heat preservation and prevent the valve and pipeline from freezing, the processing is too complicated, and the subsequent sequence is also difficult. Inconvenient maintenance; some emptying devices are directly exposed to the external environment. Although they...

Abstract

The invention relates to the technical field of solar water heaters and discloses a pipeline evacuation valve. The pipeline evacuation valve comprises a valve body, wherein water inlet and outlet holes are formed on the upper side of the valve body; and water inlet and outlet nozzles are formed on the lower side of the valve body. The pipeline evacuation valve also comprises an actuator, a driving shaft, a valve block bracket and a rotating valve block, wherein the actuator is connected with the valve body through a screw fastening-free elastic fastener; the driving shaft is inserted into an output gear hole of the actuator; two fixing rods on the valve body are additionally inserted into fixing holes of the actuator; the valve block bracket and the rotating valve block are arranged between the valve body and the actuator; and an evacuation air pipe is arranged on the upper part the valve body.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a pipeline emptying valve which can be used on pipelines of solar water heaters. Background technique [0002] As a kind of green energy, solar energy is attracting people's attention because of its advantages of inexhaustibility, no pollution, and no geographical restrictions. Solar energy technology is being rapidly promoted and applied. [0003] Solar water heaters have many advantages such as environmental protection and energy saving, convenient use, safety, etc. Therefore, they have become the first choice for people to install water heaters. [0004] At present, the operation mode of most solar water heater pipe emptying valves is realized by switching the switch of the upper and lower water and exhaust pipes. When the pipeline is connected to the atmosphere, the water in the pipeline is discharged from the lower part by gravity to achieve the emptying function. Ho...
