Specific embodiment
Essence of the invention is more fully understood for convenience of those skilled in the art, with reference to the accompanying drawing to of the invention specific
Embodiment is described in detail.
As shown in Figure 1, a kind of thermodynamic cycle valve characterized by comprising form hot-water cavity 1, cold water cavity 2 together
With check valve 3, pipe joint of hot water 4 and hot water water spot connector 5 are equipped on hot-water cavity 1,2 connect equipped with cold water pipe on cold water cavity
First 6 and cold water water spot connector 7, the check valve 3 be connected between hot-water cavity 1 and cold water cavity 2, the conducting direction of check valve 3
Cold water cavity 2 is flowed to for hot-water cavity 1.
Wherein, the hot-water cavity 1 and cold water cavity 2 are all straight tube cavity, and the pipe joint of hot water 4, cold water pipe fitting 6 are distinguished
Positioned at 2 lower end of hot-water cavity 1 and cold water cavity, the hot water water spot connector 5 and cold water water spot 7 are located at 1 He of hot-water cavity
2 upper end of cold water cavity, in order to install and use.
The check valve 3 includes: valve chamber 3-1, spool 3-2 and reset spring 3-3, and the spool 3-2 is in reset spring 3-3
Valve chamber 3-1 is separated into two cavitys in left and right under effect, when the hydraulic pressure in hot-water cavity 1 is greater than the hydraulic pressure in cold water cavity 2, is resetted
Spring 3-3 is shunk under the action of differential water pressures, and the cavity conducting of left and right two, water flow flows to cold water cavity 2 from hot-water cavity 1.
Further, several plastic shells 10 are also connected on check valve 3, each plastic shell 10 is combined list
It is wrapped to the outer surface of valve 3, compact-sized, good appearance.
When practical application, thermodynamic cycle valve is set at the hot water water spot farthest away from gas heater, works as gas and hot water
When device opens warm-up cycle mode, recirculated water can only unidirectionally flow into cold water pipe from hot-water line, to make gas heater-hot water
Pipe-cold water pipe forms a circulation line, and loop structure is simple.
Particularly, it to avoid the accidental activation using gas heater when cold water, is additionally provided at cold water water spot connector 7
Constant-current stabilizer 8.8 flow control condition of constant-current stabilizer are as follows: when pressure of supply water is in 0.1~1MPa, 5L/min≤water flow≤7L/
min。
As shown in Figure 2 and Figure 3, the constant-current stabilizer 8 includes: core 8-1 and elastic ring 8-2, at cold water water spot connector 7
Equipped with inwardly projecting supporting part 9, the elastic ring 8-2 and supporting part 9 are against the core 8-1 is compressed under flow action
On elastic ring 8-2.
The working principle of constant-current stabilizer 8: when hydraulic pressure is zero, elastic ring 8-2 is indeformable；When there is hydraulic pressure, elastic ring 8-2
It is influenced by hydraulic pressure, is inwardly squeezed, reduce water stream channel, thus the stationary flow amount in the case where hydraulic pressure increases；Pressure is got over
Greatly, what elastic ring 8-2 was extruded is more severe, to reduce the gap passed through, more to have the function that stationary flow amount；When
Pressure reduces, and elastic ring 8-2 is shunk, and water flow is become larger by gap.
A kind of thermodynamic cycle valve provided in this embodiment is constructing together with the molding of hot-water cavity, cold water cavity and check valve
When hot water cyclesystem, without installing check valve additional, structure is simple, convenient for sealing, easy to install and use, is particularly suitable for building without returning
The water heater hot-water circulatory system of water pipe.Meanwhile by the way that constant-current stabilizer is being arranged in cold water water spot joint, effectively solve to make
The problem of being started with water heater when cold water.
The above specific embodiment is described in detail for the essence of the present invention, but can not be come with this to of the invention
Protection scope is limited.It should be evident that under the inspiration of the essence of the present invention, those of ordinary skill in the art can also be into
The many improvement and modification of row, it should be noted that these improvement and modification all fall in claims of the invention it
It is interior.
