Detailed Description

In order to more clearly and completely explain the technical scheme of the present invention, the present invention is further explained with reference to the attached drawings.

Referring to fig. 1-4, the utility model provides a tap water anti-freezing pressure relief device, which comprises a heat preservation pot body 10, a breather valve 16, an inner container 17, a conduit 18 and a water pipe 19, the heat preservation pot body 10 comprises a heat preservation pipe 11, an upper shell 13 and a lower shell 12, the bottom of the lower shell 12 is fixedly connected with the heat preservation pipe 11, the heat preservation pipe 11 is communicated with the lower shell 12, the water pipe 19 is accommodated in the heat preservation pipe 11, the inner container 17 is accommodated in the lower shell 12, one end of the conduit 18 is fixedly connected with the water pipe 19, the other end of the conduit 18 is fixedly connected with the inner container 17, the conduit 18 communicates the water pipe 19 with the inner container 17, a gap is reserved between the inner container 17 and the inner wall of the lower shell 12, the upper shell 13 is fixedly connected with the lower shell 12, and the breather valve 16 is mounted at the top of the upper shell 13. The joint of the lower shell 12 and the insulating pipe 11 is provided with a through hole 14, and the inner container 17 is communicated with the water pipe 19 at the through hole 14 by the guide pipe 18. The top of the upper shell 13 is provided with a mounting hole 15, and the breather valve 16 passes through the mounting hole 15 so that the breather valve 16 can be mounted on the upper shell 13. The anti-freezing tap water pressure relief device further comprises a first heating wire 20 and a second heating wire 21, wherein the first heating wire 20 is wound and fixed on the periphery of the water pipe 19, and the second heating wire 21 is wound and fixed on the periphery of the inner container 17. The upper shell 13 and the lower shell 12 are made of transparent materials. The periphery of the inner container 17 is coated with a light absorption material layer, and the light absorption material layer can be selected in various ways.

In the present embodiment, the breather valve 16 is a one-way breather valve 16. One end of the water pipe 19 is connected with the water pipe 19, and the other end is connected with a water tap. The inner bag 17 with there is certain space between the casing 12 down, the inner bag 17 with the inner wall of casing 12 is contactless down, like this the inner bag 17 with just can form the one deck air bed between the casing 12 down, can play fine heat preservation effect. The upper shell 13 and the lower shell 12 are transparent, so that the inner container 17 can absorb light better, and the inner container 17 can be heated. The first heating wire 20 and the second heating wire 21 can assist in heating and insulating the water pipe 19 and the inner container 17. The first heating wire 20 and the second heating wire 21 are connected to a solar power supply device. At present all less in the solar energy constant temperature freeze-proof device in extremely cold region uses, and it is more rare to install solar device on tap's freeze-proof device, so the utility model discloses an among the frostproofing pressure relief device of running water, be connected to solar power system to the heater strip, then the inner bag also can pass through the heat of light-absorbing layer absorption solar energy, heat the heat preservation to the water in the inner bag, transparent housing makes the sunlight can transmit on the inner bag, two heater strips of solar power system heating, the inner bag absorbs solar heating, dual solar heating heat preservation function can play fine frostproofing effect.

In this embodiment, the working process of the anti-freezing and pressure-releasing device for tap water is as follows: before water is discharged, the water tap is closed, water flows into the water pipe 19 from the pipeline, when the water flows into the water pipe 19, air in the pipeline enters the upper part of the inner container 17 from the guide pipe 18, then the breather valve 16 on the top of the upper shell 13 is jacked up, the mounting hole 15 is pressed and sealed by the rubber pad on the breather valve 16, and the whole thermos body 10 is in a state of not being communicated with the outside. The water level in the inner container 17 drops and air cannot escape due to the water pressure and the action of the breather valve 16. When water is not discharged, the water level in the inner container 17 rises or falls, and pulsation is formed, so that the water in the conduit 19 cannot stand still, and the effect of difficult icing is achieved. When water is cut off, the air in the thermos body 10 presses the water in the inner container 17 back to the water pipe 19, at the moment, the air pressure in the thermos body 10 returns to normal, the breather valve 16 is opened, and then the water in the inner container 17 completely returns to the water pipe 19. Under the conditions of water existence and water cut-off, after the water tap is closed, due to the existence of the tap water anti-freezing pressure relief device, the section of the pipeline connected with the water pipe 19 and the water tap is in an emptying water-free state, so the water tap provided with the device can have an anti-freezing effect outdoors.

Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
