Abstract

The utility model discloses an anti-freezing device for the pipelines of s solar energy water heater, which comprises a water tank; the water tank is connected with a water charging pipe, a water outlet pipe, and a water charging valve. The utility model is characterized in that the water charging pipe connected with the water tank is vertically lifted upwards and is installed above the water discharging pipe; the axis joint of the water charging pipe is provided with a one-way air inlet valve at the segment that the water charging pipe is in parallel with a water outlet pipe, and the water outlet pipe is provided with a water discharging valve. With the adoption of the utility model, the pipelines exposed outside a room can not be frozen in winter; the service is extended thereby; moreover, the operation is convenient, and the antifreezing effect can be achieved.

Description

Defroster on the solar energy water heater pipe

The utility model relates to a kind of solar water heater, is specially adapted to the defroster on the winter solar energy water heater pipeline.

Present solar water heater in order to prevent that pipeline from freezing, generally adopts heat-insulation layer to nurse on pipeline, but fundamentally can't resolve frozen problem in the winter time, moreover the cost height, operational difficulty, and heat insulating coefficient is poor.

The utility model proposes defroster on a kind of cost is low, heat insulating coefficient is high, the simple to operate solar energy water heater pipe at the problems referred to above.

Task of the present utility model is finished as follows, it comprises water tank, be connected with upper hose and outlet pipe, water supply valve on the water tank, it is characterized in that: the vertical raising of the upper hose that connects on the water tank is installed in the outlet pipe top, in the parallel section of upper hose with outlet pipe, on the axis joint of upper hose breather cheek valve is installed, replenishes on the pipe at cold water draining valve is installed.

The utlity model has following effect, adopt this defroster, expose the piping outside the house in the winter time and can not freeze, increase the service life, and have easy and simple to handlely, and can reach antifreezing effect, is present solar water heater desirable defroster in the winter time.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of embodiment 2 of the present utility model.

Describe embodiment in detail in conjunction with above accompanying drawing.On the water tank 1 of existing solar water heater, be connected with upper hose 5 and outlet pipe 4, constitute water-flow circuit, upper hose 5 vertically is higher than outlet pipe 4, in upper hose 5 and outlet pipe 4 parallel sections, on the axis joint of upper hose 5 breather cheek valve 2 is installed, replenishes at cold water a draining valve 8 is installed on the pipe 7.Open water supply valve 9 during use, water enters water tank through upper hose 5, at this moment opens draining valve 8, water sprays through spray head 6 under the effect of exhaust outlet 3 decompressions through outlet pipe 4, during as hydro-thermal at this moment, draining valve 8 leaves greatly, and cold water replenishes and enters spray heads 6 ejections through replenishing pipe 7.As in the winter time, daytime and night the temperature difference big, long-pending in the pipe have water to freeze according to the temperature in the external world, for antifreeze, at first to discharge the ponding in the pipe, at this moment open draining valve 8, at this moment the function of the breather cheek valve 2 on the upper hose 5 is that gas makes the water in the pipe discharge through spray head 6 through this valve input channel, ponding in the emptying pipe, but upper hose A-B section ponding is difficult to emptying, improves heat insulating coefficient so outer section is added with heat-insulation layer.

Embodiment 2, and is antifreeze in order better to solve the A-B segment pipe, this segment pipe stretched into through water tank 1 left end flood in the water, and the A-B segment pipe can not expose the external world, thereby reaches antifreeze purpose.Outlet pipe 4 constitutes water-flow circuit at the right-hand member of water tank 1.Thereby reach antifreeze purpose.

Claims

1, the defroster on the solar energy water heater pipe, it comprises water tank, be connected with upper hose and outlet pipe, water supply valve on the water tank, it is characterized in that: the vertical raising of the upper hose that connects on the water tank is installed in the outlet pipe top, in the parallel section of upper hose with outlet pipe, on the axis joint of upper hose breather cheek valve is installed, replenishes on the pipe at cold water draining valve is installed.
