Description

Mechanical temperature control monostable water return device

Technical Field

A water return device for closing a connecting passage between cold and hot water pipes by overcoming the force applied by a spring when a mechanical temperature control element is thermally expanded.

Background

All can have the demand of using hot water in domestic and public environment, nevertheless because the hot water source often can have a certain distance with the water end to cause to be detained the water after a large amount of coolings in the pipeline, simultaneously because ordinary water injection well choke does not have the backward flow function, thereby lead to producing a large amount of water of abandoning before using hot water. The washbasin is used for washing hands frequently, and is also an application link which causes the highest frequency of water abandonment, so that the problem of water abandonment of the washbasin is solved, and fresh water resources can be saved more effectively. The existing circulating device is provided with a special water return pipeline to form a circulating loop so as to circulate hot water, so that a user who does not have the special water return pipeline is difficult to realize a circulating function; meanwhile, due to the temperature control automatic circulation system, a user cannot start the system as required, so that a large amount of circulation idle consumption and pipeline heat dissipation idle consumption are generated when the system is idle, and the cost of water saving is changed into a large amount of electric energy consumption. The invention has the advantage that the controllable water return channel can be constructed without laying a special water return pipeline.

as shown in the attached figure 1, when pressure exists in the hot water pipeline, a water body in the hot water pipeline can flow into the hot water cavity 6 from the hot water pipe inlet 7, then flow into the check valve 23 in the cold water cavity 8 from the water passing hole of the middle partition 5, flow into the cold water cavity 8 through the anti-siphon valve core 27, and flow into the cold water pipeline from the cold water pipe inlet 11, when a water body with a specified temperature flows into the hot water cavity 6, due to the pushing of the thermal bulb 15, the sealing plug 19 moves towards one end of the water passing hole and blocks the water passing hole, and at this time, the water body flowing into the hot water cavity 6 from the hot water pipe inlet 7 can flow out to the water end equipment from the; the water in the cold water pipeline can flow into the cold water cavity 8 from the inlet 11 of the cold water pipe and then flow out to the water end equipment from the outlet 13 of the cold water pipe;

further, if one uses only cold water, as shown in fig. 2, the water flowing from the inlet 11 of the cold water pipe will impact the water-driven sliding piece 29 to make it slide to the other end along the axial direction, and the position of the water-driven sliding piece can block the axial core of the check valve 23 to prevent the water from opening, thereby preventing the hot water from entering the cold water chamber 8.
