Problems solved by technology

If things go on like this, it has not only caused a lot of waste of water resources, but also increased the additional expenses of users
[0003] At present, there are some technologies that can solve the above problems. For example, the temperature-adjusting cold and hot water diverter valve disclosed in Chinese Patent No. 201420249760.1 can solve the problem of cold water backflow, but it has the following problems: When water leaks or is thought to cause water leakage, the piston is prone to misjudgment and starts to work, which will waste hot water resources; cold water is easy to flow back into the piston during backflow, which makes the diversion efficiency poor and leads to slow hot water supply

Embodiment 1

[0029] Such as Figure 1 to Figure 6 As shown, the hot and cold water diverter valve includes an outer sleeve 1 with both ends closed and hollow, and the outer sleeve 1 is provided with a diversion cavity 11 and a return cavity 12 and a hot water cavity 13 respectively located on both sides of the diversion cavity 11 , the return chamber 12 communicates with the diversion chamber 11 through the first port 14, the hot water chamber 13 communicates with the diversion chamber 11 through the second port 15, and the return chamber 12 is provided with a one-way valve 4 communicated with the first port 14 A hollow piston cylinder 2 is provided in the shunt cavity 11, a certain gap exists between the outer wall of the piston cylinder 2 and the inner wall of the outer sleeve 1, and an annular groove 25 is arranged on the outer wall of the piston cylinder 2, the outer sleeve 1 A water inlet 16, a hot water outlet 17 communicating with the hot water chamber 13, and a return water outlet ...

Embodiment 2

[0033] This embodiment makes the following further limitations on the basis of Embodiment 1: the one-way valve 4 includes a valve body 41 with both left and right ends open, the left end opening of the valve body 41 communicates with the first port 14, and its The right end opening communicates with the return water outlet 18, and the valve body 41 is provided with a sealing head 42 and a third elastic member 44 whose left end closes the right end opening. A plurality of fourth through holes 43 communicating with the opening end of the sealing head 42 are provided on the side wall of the sealing head 42 , and the third elastic member 44 acts on the opening end of the sealing head 42 so that the sealing head 42 closes the left end opening of the valve body 41 . When this embodiment is applied, if Figure 5 As shown, the water flows into the valve body 41 through the left end opening of the valve body 41. Due to the pressure of the water flow, the sealing head 42 will overcome t...

Embodiment 3

[0035] This embodiment makes the following further limitations on the basis of any one of embodiments 1 to 2: the left end cover 6 is provided with mounting holes 61 that pass through the left and right end faces of the left end cover 6, and the elastic component 5 includes and installs The temperature regulating rod 51, the second elastic member 52 and the pressure sleeve 53 are threadedly matched with the hole 61. The temperature regulating rod 51 is placed in the end of the mounting hole 61 to be provided with an inner hole 54, and the inner hole 54 and the pressure sleeve 53 are respectively sleeved on the two ends of the second elastic member 52 . In this embodiment, in order to improve the stability of the interaction between the elastic component 5 and the temperature-sensitive actuator 3, the left end cover 6 should be provided with a sufficient thickness to ensure that the inner hole 54, the second elastic member 52 and the pressure sleeve 53 are all located in the ins...

Abstract

The invention discloses a shunt valve for cold water and hot water. The shunt valve comprises an outer sleeve, wherein a shunt cavity, a reflow cavity and a hot water cavity are formed in the outer sleeve; the reflow cavity is communicated with the shunt cavity by a first communicating opening; the hot water cavity is communicated with the shunt cavity by a second communicating opening; a one-way valve is arranged in the reflow cavity; a piston cylinder is arranged in the shunt cavity; a certain clearance is reserved between the outer wall of the piston cylinder and the inner wall of the outer sleeve; a first through hole, a second through hole and a third through hole are formed in the cylinder wall of the piston cylinder; a temperature sensitive actuator and a first elastic element are arranged in the piston cylinder; a seal disc is arranged on the temperature sensitive actuator; an elastic component is arranged on the inner wall of the outer sleeve. According to the shunt valve disclosed by the invention, accurate shunting of the cold water and the hot water can be realized by sliding fit between the piston cylinder and the outer sleeve; meanwhile, the water outlet temperature of hot water can be regulated according to the demand; the shunt valve has the advantages of accurate judgment, high reflow efficiency, stable operation and long service life.

Description

technical field [0001] The invention relates to the technical field of heating valves, in particular to a cold and hot water diverter valve. Background technique [0002] In modern life, since the water supply pipe of the hot water supply system usually has a certain length, when hot water is used, a certain amount of retained cold water must be discharged every time to supply hot water, especially when the water point is far from the hot water supply point. This problem is particularly prominent at a distance. If things go on like this, it has both caused a large amount of waste of water resources and increased the additional expenses of users. [0003] At present, there are some technologies that can solve the above problems. For example, the temperature-adjusting cold and hot water diverter valve disclosed in Chinese Patent No. 201420249760.1 can solve the problem of cold water backflow, but it has the following problems: When water leaks or is thought to cause water l...
