Description

The tap water supply system of frost-cracking-preventing

Technical field

The tap water supply system of specifically a kind of frost-cracking-preventing of the utility model, belongs to supply equipment technical field.

Background technology

Existing tap water supply system usually by being formed for water tower and feed pipe, passes through feed pipe for the water in water tower To be transported to each user's family, tap water supply system was uninterruptedly supplied water using 24 hours at present, was had always in feed pipe certainly Water, user can use at any time.When not having user's water, the water in feed pipe is static, immobilising, and only user exists During with water, the water in feed pipe just flows, this results in winter temperature in subzero, the water freezing in running water pipe, from And leading to water supply tracheal rupture, tap water can not be normally transported in user family by feed pipe, seriously affect user's water, to people Daily life bring inconvenience.On the other hand, after running water pipe bursting by freezing, maintenance load is big, and maintenance cost is high, repair It is difficult.

Invention content

The utility model provides a kind of tap water supply system of frost-cracking-preventing, can be effectively prevented feed pipe in winter by Bursting by freezing does not influence the just common water of user.

To achieve these goals, a kind of tap water supply system of frost-cracking-preventing of the utility model, including for water tower, water supply Pipe and water inlet pipe, the water inlet pipe accessing user family, the feed pipe one terminate water supply tower, and the other end taps into water pipe, also wraps Return pipe is included, the return pipe one terminates water supply tower, and the other end is connected with feed pipe, and the feed pipe is set with return pipe connectivity part There is shut-off valve, several water receiving pipes are equipped on the return pipe and feed pipe.

Further, drainpipe is equipped with positioned at the return pipe for water tower side, drainpipe is equipped with drain valve, the draining Pipe and the return pipe supplied between water tower are equipped with back-water valve (BWV).

Further, hot-water line is equipped with positioned at the feed pipe for water tower side, hot-water line is equipped with hot water valve, the hot water Pipe and the feed pipe supplied between water tower are equipped with feed water valve.

Compared with prior art, the utility model is equipped with the return pipe connected with feed pipe and for water tower, and tap water is from confession Water tower exits into feed pipe, then is flowed back into via return pipe for water tower, so as to ensure that the water in feed pipe always in stream Dynamic state, the water in feed pipe would not freeze less than subzero temperature in winter, and showing for bursting by freezing would not also occur for feed pipe As.The utility model is additionally provided with shut-off valve, in temperature higher than in the case of zero degrees celsius, icing phenomenon will not occur, can close Shut-off valve is closed, tap water is blocked to be flowed back to through return pipe for water tower.The utility model is simple in structure, easily fabricated, and manufactures cost It is low.

Description of the drawings

Fig. 2 is the utility model feed pipe structure diagram.

Specific embodiment

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

As shown in Figure 1, a kind of tap water supply system of frost-cracking-preventing of the utility model, including for water tower 1,2 and of feed pipe Water inlet pipe 7,7 accessing user's family of water inlet pipe, the feed pipe 6 one terminate water supply tower 1, and the other end taps into water pipe 7, also wraps Return pipe 2 is included, the return pipe 2 one terminates water supply tower 1, and the other end is connected with feed pipe 6, and the feed pipe 6 connects with return pipe 2 Logical place is equipped with shut-off valve 8, is equipped with several water receiving pipes 62 on the return pipe 2 and feed pipe 6,2 He of return pipe positioned at ground Feed pipe 6 is connect by water receiving pipe 62 with the return pipe 2 and feed pipe 6 of underground.

Above-mentioned technical proposal is further improved as the utility model, is set on the return pipe 2 for 1 side of water tower There is drainpipe 3, drainpipe 3 is equipped with drain valve 31, and the drainpipe 3 and the return pipe 2 supplied between water tower 1 are equipped with back-water valve (BWV) 21, the tap water of reflux can be discharged to by drainpipe 3 for outside water tower 1, can also flow back to for water tower 1.

As improvement of the utility model to above-mentioned technical proposal, hot water is equipped with positioned at the feed pipe 6 for 1 side of water tower Pipe 5, hot-water line 5 are equipped with hot water valve 51, and the hot-water line 5 and the feed pipe 6 supplied between water tower 1 are equipped with feed water valve 61, by After feed pipe and return pipe are used for a long time, bacterium can be generated, water quality is polluted, so staff can pass through hot water Pipe conveys hot water into feed pipe, and hot water is allowed to be flowed in feed pipe and return pipe, plays the role of washing away to pipeline, another Aspect, hot water can also kill the bacterium in pipeline, ensure that tap water is not contaminated.

When outdoor temperature is higher than zero degrees celsius, does not need to tap water and be always ensured that flow regime, can will close shut-off valve 8, tap water reflux is blocked, with energy saving, the service life of extension return pipe 2.

When outdoor temperature is less than zero degrees celsius, shut-off valve 8, hot water valve 51 and drain valve 3 are opened, closes 61 He of feed water valve Back-water valve (BWV) 21 adds in hot water into feed pipe 6 by hot-water line 5, and hot water flows into return pipe 2 along feed pipe 6, then passes through draining Pipe 3 discharges return pipe 2, to wash away feed pipe 6 and return pipe 2, after washing away, closes hot water valve 51 and drain valve 31, opens Feed water valve 611, shut-off valve 8 and back-water valve (BWV) 21, for 1 normal water supply of water tower.For the tap water in water tower 1 through feed pipe 6 and water inlet Pipe 7 is flowed into user family, then is flowed back to through return pipe 2 for water tower 1, so as to ensure that feed pipe 6 begins with the tap water in return pipe 2 State eventually in flowing, the phenomenon that would not freezing, would not also make frost crack pipe.
