Valve upper cover 14 sets out water hole 18, and valve upper cover 14 and through hole 22 upper shed place are threaded, and the outer wall of valve upper cover 14 is provided with the connecting thread for being connected with pipeline.Be embedded with valve upper cover seal ring 13 between valve upper cover 14 and valve housing 4 closely to fix.
Valve lower cover 1 offers water inlet 24, and valve lower cover 1 and through hole 22 lower opening are threaded, and the outer wall of valve lower cover 1 is provided with the connecting thread for being connected with pipeline.Be embedded with valve lower cover seal ring 2 between valve housing 4 and valve lower cover 1 closely to fix.
The shaft core position place of valve seat 7 offers through hole I21, and spool 8 is arranged in through hole I21 with valve seat 7 in being slidably matched; Valve seat 7 is arranged between valve upper cover 14 and valve lower cover 1 and makes valve seat 7 and valve housing 4 be in relative static conditions.
The sidewall of valve seat 7 offered mouth of a river IV7a and crossed water breach 7b, the slip along with spool 8 made mouth of a river IV7a and crossed mouth of a river III8c and is communicated with/misplace, served as mouth of a river IV7a with mouth of a river III8c be communicated with time, groove runner 8d and water breach 7b misplace; Served as mouth of a river IV7a with when mouth of a river III8c misplaces excessively, groove runner 8d is communicated with mistake water breach 7b.
Return spring 12 is placed on valve gap 11, and one end and valve upper cover 14 offset, and the other end and valve gap 11 offset.
Valve gap 11 comprises the boss 20 that shape is cylinder, and the shaft core position place of boss 20 offers through hole I19, and boss 20 outer wall is embedded with seal ring 10, is formed seal after making boss 20 stretch into stroke hole 8e with stroke hole 8e inwall.
Spool 8 offers stroke hole 8e, crosses mouth of a river I8a, crosses mouth of a river III8c, groove runner 8d.Stroke hole 8e offers along the axial direction of spool 8, crosses the bottom that mouth of a river II8b is opened in stroke hole 8e; Cross mouth of a river I8a, excessively mouth of a river III8c and groove runner 8d to offer along the radial direction of spool 8.The lower end surface place that groove runner 8d is positioned at spool 8 is provided with opening for being communicated with water inlet 24.Cross mouth of a river I8a to be communicated with groove runner 8d by stroke hole 8e, mouth of a river III8c is communicated with mistake mouth of a river II8b excessively;
Steel ball 9 is movably placed in the 8e of stroke hole as Sealing, and the sphere diameter of steel ball 9 was greater than the bore of mouth of a river II8b and was also greater than the aperture of through hole I19 simultaneously; Making to seal when steel ball 9 can be formed with mistake mouth of a river II8b when being positioned at II8b position, the mouth of a river, can be formed with this opening when steel ball 9 is positioned at the through hole I19 aperture position place of boss 20 and sealing.
As Fig. 3, valve housing 4 inwall offers and the ring runner 4a being connected the mouth of pipe 23 and being communicated with, and valve housing 4 inwall offers and the ring runner 4b crossing water breach 7b and is communicated with, and osculum 18 is communicated with ring runner 4b by mistake water breach 7b.
The lower end of temperature sensing spring 3 one end and spool 8 offsets, and the other end and valve lower cover 1 offset.
As seen from Figure 3, when steel ball 9 and when excessively sealing between the II8b of the mouth of a river, a kind of water route A is formed, successively by water inlet 24 → temperature sensing spring, 3 → groove runner 8d → mistake mouth of a river I8a → stroke hole 8e → through hole I19 → return spring 12 → osculum 18.
There is Fig. 2 and 4 visible, when sealing between steel ball 9 and through hole I19, form a kind of water route B, successively by water inlet 24 → temperature sensing spring, 3 → groove runner 8d → mistake mouth of a river I8a → mistake mouth of a river II8b → mistake mouth of a river III8c → mistake mouth of a river IV7a → ring runner 4a → one-way valve 16 → connection mouth of pipe 23 → cold water three-way pipe 17.
There is Fig. 5 visible, when spool 8 upward sliding, form a kind of water route C, successively by water inlet 24 → temperature sensing spring, 3 → groove runner 8d → mistake water breach 7b → ring runner 4b → osculum 18.
The working principle of above-mentioned cold and hot diverter valve is as follows: be connected with hot water pipeline water inlet 24, and osculum 18 is connected with hot water tap or shower, and three mouths of pipe of cold water three-way pipe are respectively with cold water water tap, cold water pipes and be connected the mouth of pipe 23 and be connected.
When hot water tap and shower are not opened, the water of valve housing 4 inside remains static, therefore steel ball 9 was positioned at II8b position, the mouth of a river and crossed mouth of a river II8b and formed and seal, and spool 8 is in initial position made mouth of a river IV7a and crossed mouth of a river III8c and is communicated with, simultaneously groove runner 8d misplaces with mistake water breach 7b.As shown in Figure 2,3, 4 when hot water tap and shower are opened (namely osculum 18 water outlet pressure release), steel ball 9 promotes by bernoulli principle to move the through hole I19 position seals of boss 20, water can only successively through mouth of a river II8b, cross mouth of a river III8c, cross mouth of a river IV7a, connect the mouth of pipe 23 and flow in cold water three-way pipe.
As shown in Figure 6, when hot water in hot-water line flows into, temperature sensing spring 3 deformation promotes spool 8 and moves, made mouth of a river IV7a and crossed mouth of a river III8c to misplace, groove runner 8d is communicated with mistake water breach 7b simultaneously, therefore hot water cannot flow into and connect in the mouth of pipe 23, and hot water flows out from osculum 18 through groove runner 8d, excessively water breach 7b successively.When not needing to use hot water, close hot water tap and shower (namely osculum 18 is closed), the water of valve housing 4 inside remains static, steel ball 9 resets and sealed mouth of a river II8b, along with the water of valve housing 4 inside turns cold, return spring 12 drives spool 8 to reset.
Adopt said structure, be connected with hot water end water tap by osculum 18, water inlet 24 is connected with hot water pipeline, and cold water three-way pipe one end is connected with cold water end water tap, and the other end is connected with cold water pipes, hot water pipeline is arranged the recycle pump of water switch.When closed tap, the water in pipeline remains static, and seals under steel ball 9 gravitate and between spool 8 mistake mouth of a river II8b; When opening hot water end water tap, form water route A as Fig. 3; Under steel ball 9 drives by current, seal between upward sliding and through hole I19, now hot water end water tap does not go out hot water, forms water route B such as Fig. 4 and changes; When water temperature in hot water pipeline raises arrival predefined value, temperature sensing spring 3 deformation promotes spool and moves, and forms water route C such as Fig. 5 and changes; Water tap goes out hot water.
Cold and hot shunt valve can be accessed at each water spot of the circulation loop of family expenses, user is when using the hot water of a certain water spot, because other liquid with the cold and hot shunt valve inside of water spot remains static, seal under steel ball 9 gravitate and between spool 8 mistake mouth of a river 8b, therefore other water with water spot cannot circulate; So the water in hot-water line only can carry out local circulation between use point and heater, greatly reduce the consumption of heater electric energy.And the setting of one-way valve 16 is in order to anti-sealing is back to cold and hot shunt valve from cold water pipe.
