Detailed ways

Embodiment one,

As shown in Figure 1, the waterway antifreeze protection device described in the utility model can be used in conjunction with one or more, connected to the water pipe and/or water pipe connection and/or in the water valve, as long as the position that needs antifreeze can be configured . In the following, the structure of each part will be explained according to the figure. Figure 1 shows the position of the waterway antifreeze protection device in the waterway system of the sanitary ware. The waterway antifreeze protection device can be installed on the inlet waterway of the valve body, and the distance from the valve body should not exceed 1m. Alternatively, the waterway antifreeze protection device can be integrated into the valve body as a whole.

Figure 2 shows the first structure of the waterway antifreeze protection device. It includes: a chamber, forming a certain space inside the chamber; a pressure-bearing structure, the pressure-bearing structure is located inside the chamber, the pressure-bearing structure is in contact with the water, and bears the pressure of the water; an elastic structure, the elastic structure is in contact with the bearing The pressure structure is connected to the chamber. There is a sealing structure between the pressure-bearing structure and the chamber; one end of the elastic structure is connected to the pressure-bearing structure, and the other end is connected to the chamber; the chamber has an exhaust hole. The elastic structure is a spring or an elastic material; the sealing structure is a sealing ring. The cryogenic freezing of water shows that the volume of water expands as it freezes. Before the pipeline is completely frozen, the liquid part is continuously squeezed by the ice so that the pressure in the pipeline space increases. The direction of the water pressure in the figure indicates the direction of the pressure increase. The chamber communicates with the atmosphere, and there is air in the chamber under normal conditions. When the pressure of the waterway increases due to freezing, the pressure-bearing structure moves under force, the elastic element (such as a spring) is squeezed, and the chamber space is compressed. Finally, the extra space due to the compression of the elastic element compensates for the expansion volume of the ice. When the ice dissolves, the elastic element drives the pressure-bearing structure back, and the chamber expands to its original shape.

Embodiment two,

Figure 3 shows the second structure of the waterway antifreeze protection device. The structure is simplified based on the structure in FIG. 2 , the elastic structure is an elastic material, and the pressure-bearing structure is the outer surface of the elastic structure. The elastic element is used as a pressure-bearing structure (such as a rubber cushion), and the elastic element has a certain degree of elasticity and is difficult to be compressed under normal working water pressure. When the waterway pressure increases due to low-temperature freezing, the elastic element is compressed to reduce its volume, which increases the original space of the pipeline; when the ice melts, the elastic element returns to its original volume.

Embodiment three,

Figure 4 shows the third structure of the waterway antifreeze protection device. The pressure-bearing structure is connected with a piston; the chamber is provided with a pressure relief port, when the water pressure rises to the set pressure, the piston is pushed, and the water is released from the pressure relief port; when the pressure drops to the set pressure, The piston returns to its original position and seals the waterway. The pressure relief port is arranged on the side wall of the chamber; and/or the pressure relief port is arranged at a position opposite to the piston, and a water guide groove is arranged on the piston, through which water can flow into the chamber and be discharged from the pressure relief port. As shown in Figure 4, a pressure relief port is added on the basis of the structure in Figure 2. When the water pressure rises, the piston is pushed, and the liquid is released from the pressure relief port. When the pressure drops to the set pressure (this pressure can be the pressure of the spring itself, or can be set by the additional pressure regulating mechanism), the piston returns to seal the waterway. Wherein, the pressure relief port can be arranged on the side wall of the chamber, and can also be arranged at a position opposite to the piston, and water can flow through a water guiding groove (shown by a dotted line) arranged on the piston. The advantage of multiple pressure relief ports is to increase the reliability of the discharge flow, that is, when one pressure relief port is blocked, the other pressure relief ports can be used for pressure relief. The main difference between this embodiment and Embodiment 1 is that a piston, a pressure relief port and a water guide groove are added. Other parts that are the same as those in Embodiment 1 will not be repeated here.

Only need to add the elastic buffer structure in the upstream pipeline of accessories (such as valves), it can play anti-freezing effect, and can be used repeatedly, the structure is compact, and it is economical and applicable. The utility model provides a waterway antifreeze protection device suitable for internal pipelines of sanitary ware. The device can effectively prevent the risk of expansion and cracking of pipelines and fittings caused by low-temperature freezing. The device has a small and compact structure, can be connected separately in the pipeline or integrated with the valve, can be well compatible with the design of sanitary ware products, and has low cost.
