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 cold and hot water diversion valve includes an outer sleeve 1 with both ends closed and hollow. 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 reflux chamber 12 communicates with the shunt chamber 11 through the first port 14, the hot water chamber 13 communicates with the shunt chamber 11 through the second port 15, and the reflux chamber 12 is provided with a one-way valve 4 communicating with the first port 14. , A hollow piston cylinder 2 is provided in the distribution chamber 11, and there is a certain gap between the outer wall of the piston cylinder 2 and the inner wall of the outer sleeve 1. The outer wall of the piston cylinder 2 is provided with an annular groove 25, and the outer sleeve 1 The cylinder wall is provided with a water inlet 16, a hot water outlet 17 communicating with the hot ...

Embodiment 2

[0033] This embodiment further defines the following on the basis of embodiment 1: The one-way valve 4 includes a valve body 41 with both left and right ends open, and the left end opening of the valve body 41 communicates with the first port 14, and The right end opening is in communication with the return water outlet 18. The valve body 41 is provided with a head 42 with a left end closing the right end opening and a third elastic member 44. The width of the closed end of the head 42 is greater than the width of the left end of the valve body 41. The head 42 A plurality of fourth through holes 43 communicating with the open end of the head 42 are provided on the side wall of the, and the third elastic member 44 acts on the open end of the head 42 so that the head 42 closes the left end opening of the valve body 41. When this embodiment is applied, such as Figure 5 As shown, water flows into the valve body 41 through the left end opening of the valve body 41. Due to the pressu...

Embodiment 3

[0035] This embodiment further defines the following on the basis of any one of Embodiments 1 to 2: The left end cover 6 is provided with mounting holes 61 penetrating the left and right end faces of the left end cover 6, and the elastic component 5 includes The temperature control rod 51, the second elastic member 52 and the pressure sleeve 53 are threadedly fitted in the hole 61. The temperature control rod 51 is placed in the end of the mounting hole 61 and is provided with an inner hole 54. The inner hole 54 and the pressure sleeve 53 are respectively sleeved 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 sensing actuator 3, the left end cover 6 should be provided with sufficient thickness to ensure that the inner hole 54, the second elastic member 52 and the pressure sleeve 53 are all located in the installation 孔61. In addition, in order to realize the s...

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 diversion valve. Background technique [0002] In modern life, because the water supply pipe of the hot water supply system usually has a certain length, when hot water is used, a certain amount of stored cold water must be discharged each time to supply hot water, especially when the water point is relatively far from the hot water supply point. When it is far away, this problem is particularly prominent. If things go on like this, it will not only cause a lot of waste of water resources, but also increase 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 the hot water faucet is naturally...
