The present invention relates to a urine washing valve equipped with a freeze protection structure, and more particularly, in a urine washing valve which can control the supply of washing water by a drain valve body which is elevated by hydraulic pressure, a small amount of washing water in the valve chamber. By installing a bypass control valve to drain the water to the drain pipe, it is possible to prevent freezing caused by freezing of the washing water in winter, and to prevent the occurrence of odor by draining the washing water in a certain amount in the summer. The present invention relates to a urine washing valve having a freeze protection structure that includes a thermal expansion and contraction portion in a pass control valve so that the bypass flow rate is variable according to temperature change, thereby preventing freezing caused by freezing even when the temperature drops rapidly.

In general, the urinal is installed with a urine washing valve to discharge the wash water after use to wash the urinal, such a urine washing valve is installed in the drain valve body 220 as shown in Figure 1 by a certain amount of washing water for a certain time To ensure that the urinal is kept clean.

The urine washing valve includes a valve chamber 210 and a valve chamber configured to have a water supply port 212 connected to a water supply pipe 310 at an upper portion thereof, and to discharge the washing water introduced through the water supply hole 212 at a lower portion thereof. The drain valve body 220 is stored in the water supply pipe 310 to control the flow of the wash water from the water supply pipe 310 to the drain pipe 320, and the drain valve body to maintain the drain blocking force by the drain valve body 220 by the water pressure of the wash water The valve block 210 of the valve chamber 210 so that the hydraulic pressure of the washing water flowing through the drain blocking water pressure supply passage 221 communicating with the upper side at the side of the 220 and the hydraulic pressure of the washing water introduced through the drain blocking water pressure feeding passage 221 can act on the upper side of the valve body. The blocking pressurizing chamber 211 formed at the upper side and the washing water of the blocking pressurizing chamber 211 are drained so that the drainage valve body 220 is drained to flow the washing water from the blocking pressurizing chamber 211 to the water supply pipe 310. It was composed of a drain induction valve 230 for controlling.

In the conventional urine washing valve, when the user presses the pushbutton 330, the induction bar 231 of the drainage induction valve 230 is pushed, and the pressing force is discharged while the washing water in the blocking pressure chamber 211 is discharged to the drain pipe 320. As the drain valve body 220 is raised by the water pressure of the washing water introduced through the water supply pipe 310, the water passage is connected to the drain pipe 320 from the water supply pipe 310 to drain the washing water.

By the way, when the conventional urine washing valve is not used, the washing water does not flow and remains, and each component is made of a material having high thermal conductivity, so the washing water inside is rapidly cooled by the outside temperature and freezes. There was a problem.

And when the washing water is frozen, there is a problem that the odor is generated in the urinal because the washing water supply is not made to the urinal. In addition, since the flow rate remaining in the valve chamber 210 is large, the valve chamber 210 is cracked and damaged by volume expansion due to freezing of the wash water, and the PVC pipe piped in the wall is freeze, resulting in much time and cost. There was also a problem. On the other hand, in winter, there is a high concern about freezing of the urine washing valve, so there is a problem of unnecessary waste of energy by heating the bathroom.

The present invention is to improve the above problems, the purpose is to install a bypass control valve that can drain a small amount of wash water to the drain pipe in the valve chamber to prevent freezing caused by freezing of the wash water in winter In order to prevent the occurrence of odor by continuously draining the wash water in a certain amount during the summer, the bypass control valve is equipped with a thermal expansion and contraction part so that the bypass flow rate is variable according to the temperature change, so that even if the temperature suddenly drops due to freezing It is to provide a urine washing valve having a freeze protection structure to prevent freezing.
