Abstract
The utility model relates to a pipeline emptying device for a solar water heater, which belongs to the technical field of an auxiliary device of a solar water heater. The utility model comprises a water outlet and outlet pipe, a water tank, a water inlet valve and a water outlet valve, wherein the water inlet valve and the water outlet valve are positioned at the underside of the water inlet and outlet pipe, the upper part of the water inlet and outlet is connected with an electromagnetic valve through a three-way pipe, the other through port of the three-way pipe is connected with a water pipe, and the other end of the water pipe is positioned in the water tank. The upper part of the water tank is provided with an electromagnetic valve which is a normally close electromagnetic valve. In the utility model, the upper part of the water inlet and outlet pipe is provided with the electromagnetic valve, the emptying of water in a pipeline can be controlled by controlling the opening and the closure of the electromagnetic valve, and the freezing problem of the pipeline in winter can be avoided. At the time of using hot water, switching on a power supply is not needed. The utility model has the advantages of reasonable structure, convenient operation, simple installation, etc.
Description
Technical field
The utility model relates to the solar energy water heater pipe emptier, belongs to solar water heater auxiliary equipment technical field.
Background technology
The water-in and water-out pipeline opening of prior solar water heater is mostly in the water-heater water tank bottom or just, so the easy ponding of pipeline.In the winter time, particularly northern area owing to cold weather, often causes the water heater inlet tube and outlet tube to freeze, even with frost crack pipe, water heater can't normally be used.In order to be incubated, adopt usually when mounted to add insulation material around the pipeline or load onto mode such as heat tape, but effect to be not satisfactory, and to cause energy waste.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, easy to use, install simple, can prevent effectively that pipeline from freezing, the solar water heater upper and lower conduit emptier of bursting by freezing.
The utility model is achieved through the following technical measures:
The utility model comprises water inlet pipe and water outlet pipe, water tank, water intaking valve and outlet valve, water intaking valve and outlet valve wherein, are connected with magnetic valve by three-way pipe on the top of water inlet pipe and water outlet pipe below water inlet pipe and water outlet pipe, another port of three-way pipe is connected with water pipe, and water pipe is placed in the water tank.
Water tank upper is provided with the water inlet pipe and water outlet pipe opening.
Described magnetic valve is a normally closed solenoid valve.
The utility model makes the top of inlet and outlet pipe lines can be in opening state by on water inlet pipe and water outlet pipe top magnetic valve being set, thereby reaches the emptying purpose of inlet and outlet pipe lines.The course of work: when toward water tank water intake, water intaking valve is opened, and outlet valve is closed, and water enters water tank by water inlet pipe and water outlet pipe, and this moment, magnetic valve was a normally off; When the needs emptying, water intaking valve to be closed, outlet valve is opened, and connects power supply, makes magnetic valve be in opening, at this moment, can be with the water emptying in the pipeline.
The utility model uses the course of work of hot water: water intaking valve is opened, and outlet valve is closed, and injects a part of water earlier in pipeline.Then water intaking valve is closed, outlet valve is opened, and just the water in the water tank can be drawn.
The utility model is by being provided with magnetic valve on water inlet pipe and water outlet pipe top, and the open and close of control magnetic valve are controlled the interior water emptying of pipeline thereby reach, and have avoided the problem that winter, pipeline froze.In non-ice period, need not the water in the emptying pipe, other operate use the same with common water heater, have advantages such as rational in infrastructure, easy to use, that installation is simple.
