Abstract

The utility model discloses a single pipe anti-frozen device for a water supply and drainage single pipe of a solar water heater, which comprises a water pipe, and a water supply and drainage control valve of a water source and a use device, wherein the water pipe is used for communicating the water tank of the solar water heater with the a water supply source and the use device. A master control valve and a ventilator are is additionally arranged at the proper position of a pipeline section arranged above a tee point of the water pipe. The utility model has the advantages of simple preparing process, low cost, long service life, no resistance to the water flow in the pipe and reliable operation.

Description

Solar water heater single tube water does not up and down freeze device

Water did not freeze device about the utility model related to a kind of solar water heater single tube.

But solar water heater is operate as normal still to 0 ℃ of condition in the winter time-20, to guarantee the hot water supply of entire-year, its water tank is incubated, and pass through water pipe UNICOM between water source and use device, supply and discharging by valve control water, but water easily was frozen in winter in the pipe of upper and lower conduit outdoor section, so that cause the solar water heater hot water can not regular supply.For this problem, taking of having adds the ribbon heater heating on pipeline, and what have installs automatically controlled water valve control additional, and what have adds thick insulation layer, and both consumed power was dangerous again, and service life is short, easy-maintaining not.

The purpose of this utility model provide a kind of use, solar water heater single tube easy to maintenance up and down water do not freeze device, it is electricity consumption neither, also need not safeguard long service life, and the upper and lower conduit that can guarantee the water heater outdoor section is not subjected to freezingly, is that user, producer exempt trouble and worry.

For achieving the above object, the utility model is taked following design: this solar water heater single tube water does not up and down freeze device, comprise UNICOM's solar water heater water tank and supply water source and use water pipe between device and the plumbing by-pass valve control of water source and use device, the line segments appropriate location installs a master control valve, a breather additional above water pipe threeway point.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model (under the user mode)

Fig. 2 is the utility model working state schematic representation

As shown in Figure 1, the utility model comprises water pipe 4, valve 3, breather 5.

Fig. 1 is a structural representation under the utility model user mode, divider wall 6 tops are expressed as outdoor section, indoor section is represented in the below, running water by-pass valve control 1, use device (as bathtub) discharge water by-pass valve control 2 all with the prior art installation roughly the same, the utility model innovative design point is, line segments appropriate location above water pipe threeway point 401 (staff can touch) installs a master control valve 3 additional, its below is provided with a breather 5, water pipe 4 folds into from water-heater water tank 7 tops and extends to the water tank bottom opening always, is beneficial to the whole sucking-offs of the water in the water tank to be used.

The utility model has used atmospheric pressure, vacuum problem and siphon principle, and the concrete course of work can be with reference to shown in Figure 2: at first open water source supply valve door 1, the water tank filling up water; Close master control valve 3 then, open and use the device by-pass valve control 2 that discharges water, turn on breather 5, the water of this section pipeline is discharged entirely; Last valve-off 2 is closed breather 5, opens valve 3, under the airtight state of pipeline, because the gas light-water is heavy, the gas in the pipeline rises to peak and motionless, the upper end flow to low spot under water, how long the lower end pipeline discharges the water of distance, the upper end pipeline just is full of the gas of equal length.Design parameter is an amount of, and making at this moment, state is issued to the anhydrous purpose of not freezing that promptly reaches of pipeline emptying outside the room.During as the water in the need usefulness water tank, open valve 2, by the effect of siphon principle, the water of water tank the inside gets off in the same old way, for using.

Except that winter, in other three season, valve 3 is often opened, and breather cuts out, and other parts are used as usual.

The utility model has the advantage of: processing is simple, cost is low, and long service life, in-pipe flow are without hindrance, And reliable operation.

Claims

1, water does not freeze device about a kind of solar water heater single tube, comprise UNICOM's solar water heater water tank and supply water source and use water pipe between device and the plumbing by-pass valve control of water source and use device, it is characterized in that: the line segments appropriate location installs a master control valve, a breather additional above water pipe threeway point.

2, water does not freeze device about the solar water heater single tube according to claim 1, it is characterized in that: described connection solar water heater water tank water pipe folds into and extends downwardly into always the water tank bottom opening from tank top.
