Abstract

The utility model relates to a pipeline emptying valve for a solar water heater, which has a valve body, the valve body is in the shape of a tube, and a baffle plate is arranged in the valve body perpendicular to the valve body. One side of the valve body A gap is left between the baffle plate and a plunger is provided on the valve body corresponding to the baffle plate, and an outer cavity is provided outside the plunger, between the plunger and the A spring is arranged between the outer cavities, and the spring controls the lifting of the plunger; a vent hole is provided on the valve body, and a plunger is also provided at the vent hole on the valve body. The outside of the plunger is provided with an outer chamber, and a spring is arranged between the plunger and the outer chamber, and the spring controls the lifting of the plunger; the two plungers are controlled by the controller through the A spring controls the lift of the plunger. Because the utility model adopts the above-mentioned technical scheme, compared with the prior art, the utility model has the advantages of saving water and resisting freezing, and the pipeline is not easy to be blocked by freezing.

Description

Solar water heater pipe emptying valve

Technical field

The utility model relates to a valve, in particular to a solar water heater pipeline emptying valve.

Background technique

Currently used solar water heaters, in the process of use, combined with the temperature change conditions in our country, found that there are two major defects in the existing solar water heaters: 1. Waste of water resources, such as the user lives on the first floor or the second floor. Solar energy is installed on the roof of the sixth floor. , the user needs to use hot water, turn on the faucet, and the accumulated water in the sewer pipe of the solar water heater must be discharged before the hot water can flow out. Roughly estimated, 30 liters of cold water needs to be discharged, which is a waste of water, electricity and time; For example, last winter, most parts of our country encountered severe cold and severe freezing, which was rare in 50 years. Since solar water heaters were installed outdoors, all brands of solar water heaters could not be used until winter, and the pipes were frozen and blocked.

Contents of the invention

Aiming at the above existing problems, the utility model designs a solar water heater pipeline emptying valve which is water-saving and frost-resistant, and the pipeline is not easy to be blocked by freezing.

The utility model has a valve body, the valve body is in the shape of a tube, and a baffle is arranged in the valve body in a direction perpendicular to the valve body, and there is a gap between one side of the valve body and the baffle , a plunger is provided on the valve body corresponding to the baffle, an outer chamber is arranged outside the plunger, a spring is arranged between the plunger and the outer chamber, the The spring controls the lifting of the plunger; a vent hole is provided on the valve body, a plunger is also provided at the vent hole on the valve body, and an outer cavity is provided outside the plunger, A spring is arranged between the plunger and the outer cavity, and the spring controls the lift of the plunger; the controller controls the lift of the two plungers through the spring.

The utility model is installed on the water outlet of the solar water tank. When the water heater tank needs water intake, the plunger at the vent hole blocks the vent hole, the plunger at the baffle rises, and the water enters the water tank of the water heater. After the water in the water tank is full, the plunger at the baffle will drop and will be in close contact with the baffle to stop the water in the tank from flowing out; the plunger at the vent hole will fall to open the vent, so that there will be no water in the water supply pipe. If there is no water in the pipeline, the pipeline will not freeze in winter; when in use, the plunger at the baffle rises, and the plunger opens the switch of the utility model in advance if the user finishes taking a bath to empty the hot water in the pipeline. When the utility model will close the water tank upper end nozzle, the user will open the utility model with hot water to be hot water like this, and drop the utility model waterway to empty and promptly save water, reached the antifreeze purpose in winter again. Compared with the prior art, the utility model has the advantages of water saving and frost resistance, and the pipes are not easy to be blocked by freezing.
