Description

Outdoor anti-freezing water faucet

Technical Field

The invention relates to the technical field of faucets, in particular to an outdoor anti-freezing faucet.

Background

The water tap is a popular name of a water valve, is used for controlling the size of water flow to be switched on and off, and has the effect of saving water. Tap often is used for daily delivery pipe on the line, and for it is convenient at outdoor water, tap can use the water pipe to install in addition and locate unsettled installation apart from one section distance of wall body usually, but winter in the north, when outdoor ambient temperature is lower, the running water that does not flow, remains in the water pipe can take place the icing phenomenon, influences normal water, and present solution is at the water pipe outside parcel heat preservation, but the effect is not good, still can't avoid appearing the icing phenomenon. It should be noted that, as the quality of life of people increases, a water heater is generally installed at home to use hot water in winter to prevent cold water from sticking bones.

In order to solve the problems, an outdoor anti-freezing water faucet is provided.

Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1-4, an outdoor anti-freezing faucet comprises a water inlet valve 1, a pipe fitting 2 and a faucet 3 which are sequentially arranged from left to right, a water supply pipeline 4 is arranged in the pipe fitting 2, a plurality of water storage pipelines 5 are uniformly arranged in the pipe fitting 2 and below the water supply pipeline 4 in the circumferential direction by taking the water supply pipeline 4 as a center, two ends of the water supply pipeline 4 are respectively connected with the water inlet valve 1 and the faucet 3, one end of the water storage pipeline 5 close to the water inlet valve 1 is a closed end, one end of the water storage pipeline 5 far away from the water inlet valve 1 is connected with the faucet 3, a one-way valve 10 is arranged on the inner wall of the water storage pipeline 5 close to the faucet 3 to avoid backflow, a rectangular water leakage port 6 is arranged in the middle of the inner bottom wall of the water supply pipeline 4 and at the corresponding position of the water storage pipeline 5, two grooves 7 are symmetrically arranged on the upper and, the other end of the return spring 8 is fixedly connected with a plugging plate 9, and the plugging plate 9 is connected with the groove 7 in a sealing and sliding manner.

The both ends of diapire in water supply pipe 4 set up towards leaking the mouth 6 downward slopes, and the blind end of water storage pipe 5 sets up towards check valve 10 downward slopes, the mobility of make full use of running water.

The volume of the water storage pipes 5 is larger than that of the water supply pipe 4, and no residual water exists in the water supply pipe 4 at low temperature.

The small semicircular part of the pipe 2, which is contacted with the water storage pipeline 5 and the water leakage port 6, is made of heat conduction materials, and the part of the pipe 2 outside the small semicircular part is made of heat insulation materials, referring to fig. 2, heat insulation is achieved, and heat exchange can be generated in the pipe.

In the normal use process of the invention, tap water flows out through the water inlet valve 1, the water supply pipeline 4 and the water tap 3 in sequence and is used, when the invention is suspended in a low-temperature environment, the water inlet valve 1 and the water tap 3 need to be closed, and tap water is reserved in the water supply pipeline 4.

Taking the production temperature of the pipe fitting 2 as an example of 25 ℃, the return spring 8 is in a normal state at the moment, referring to fig. 1, the water temperature of the two plugging plates 9 to be opened is set to be 5 ℃, and assuming that air is ideal gas, an ideal gas equation is used: PV ═ nRT (P pressure, V gas volume, T temperature, amount of n gas species, R gas constant, approximately equal to 8.31441 ± 0.00026J/(mol · K)), i.e.: v ═ nRT/P, the volume change of the sealed space formed between the blocking plate 9 and the groove 7 at two states of 25 ℃ and 5 ℃, it is further explained here that the volume reduction of the sealed space at 5 ℃ is equal to the volume of the blocking plate 9 in the water leakage port 6, referring to fig. 3, as long as the water temperature is lower than 5 ℃, a gap is formed between the two blocking plates 9, the tap water in the water supply pipeline 4 flows into the water storage pipeline 5 through the gap and the water leakage port 6 under the action of gravity, so that no tap water remains in the water supply pipeline 4, the tap water is only frozen in the water storage pipeline 5, (explained in the background art), when the warm water is normally used, the water inlet valve 1 and the water tap 3 are opened, and during the flow of the tap water in the water supply pipeline 4, the heat thereof can be transferred to the frozen body of the water storage pipeline 5 through the heat conducting part of the pipe 2, make it melt gradually, the water after melting is used to tap 3 through check valve 10 unidirectional flow under the action of gravity, can not cause the waste of water resource, melts the in-process, and the air in the confined space is the rewarming gradually, and two shutoff boards 9 then can be to leaking mouth 6 shutoff again.

The invention automatically opens the plugging plate 9 at low temperature, so that the tap water in the water supply pipeline 4 flows into the water storage pipeline 5 through the water leakage opening 6, and is gradually melted and used during subsequent water use, thereby avoiding the freezing prevention of the tap water in the water supply pipeline 4 and avoiding the waste of water resources, and being particularly suitable for the long-distance water supply pipeline 4.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
