Embodiment
With reference to Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, switch spool on a kind of constant-temperature tap, it comprises the upper and lower valve body 1,2 of mutual sealing combination, have hot water inlet 11 on the described upper valve body 1, sealing is plugged with valve rod 3 in the upper valve body 1, for valve rod 3 is fixed in the upper valve body 1 better, described upper valve body 1 is provided with the pressure cap 12 that compresses valve rod 3; Valve rod 3 lower ends are passed quiet valve block 4 and are connected on the moving valve plate 5 by shift fork, moving valve plate 5 and quiet valve block 4 applyings sealed to each other, can be complementary with the through hole 41 on the quiet valve block 4 being provided with opening 51 on the moving valve plate 5, described moving valve plate 5 interconnects with linked block 10, linked block 10 is arranged on down the interior commentaries on classics core 6 of valve body 2 with sealing and combines, following valve body 2 sides have the hot water outlet 21 that communicates with upper valve body 1 cavity, be disposed with sealing gasket 7 from the bottom up in the valve body 2 under described, stable ceramic piece 8, dynamic porcelain piece 9, described dynamic porcelain piece 9 is connected to be changeed on the core 6, the sealing that slides over each other of dynamic porcelain piece 9 and stable ceramic piece 8, described stable ceramic piece 8 is provided with water port 81, dynamic porcelain piece 9 is provided with breach 91 and osculum 92, described osculum 92 communicates with the center hole 93 of dynamic porcelain piece 9, the center hole 93 of dynamic porcelain piece 9 links to each other with groove 61 on changeing core 6, have side channel 62 on the described commentaries on classics core 6 and communicate with groove 61, following valve body 2 sides have with side opening 62 and communicate with the inner chamber of following valve body 2 on, lower outlet 22,23.
The working principle of this product is: with reference to Fig. 2, when valve rod 3 is turned left, valve rod 3 drives moving valve plates 5 and rotates and make the opening 51 on the moving valve plate 5 be complementary with through hole 41 on the quiet valve block 4, thereby make hot water enter upper valve body 1 inner chamber from the hot water inlet 11 on the upper valve body 1, respectively by through hole 41 and opening 51 and hot water outlet 21 outflows from descending valve body 2, hot water enters the temperature regulation spool through faucet subject, through with cold water mix after enter down valve body 2 from switch spool bottom, because when valve rod 3 turns left, moving valve plate 5 drives by linked block 10 changes core 6 to left movement, thereby the breach 91 on the drive dynamic porcelain piece 9 communicates with the water port 81 on the stable ceramic piece 8, and last mixing water is through water port 81, breach 91 is from lower outlet 23 outflows of valve body 2 down.
With reference to Fig. 3, when valve rod 3 is turned right, valve rod 3 drives moving valve plates 5 and rotates and make the opening 51 on the moving valve plate 5 be complementary with through hole 41 on the quiet valve block 4, thereby make hot water enter upper valve body 1 inner chamber from the hot water inlet 11 on the upper valve body 1, respectively by through hole 41 and opening 51 and hot water outlet 21 outflows from descending valve body 2, hot water enters the temperature regulation spool through faucet subject, through with cold water mix after enter down valve body 2 from switch spool bottom, because when valve rod 3 turns right, moving valve plate 5 drives commentaries on classics core 6 by linked block 10 and moves right, thereby the osculum 92 on the drive dynamic porcelain piece 9 communicates with the water port 81 on the stable ceramic piece 8, and last mixing water is through water port 81, osculum 92, center hole 93, the groove 61 that changes on the core 6 flows out from the upper water-out mouth 22 of following valve body 2 at last.
This product recognizes in order to make the client whether the switch spool is in closed condition, be provided with spring 13 between described valve body 2 down and the linked block 10, spring 13 is provided with hoodle 14, described valve body 2 down is provided with the groove 24 of ccontaining hoodle 14, when the switch spool is in closed condition, hoodle 14 just is positioned at groove 24, and hears that hoodle 14 drops to the sound in the groove 24 under the pressure of spring 13.
This product use the single switch spool to realize flow switch and control leading water outlet and the shower nozzle water outlet between switching, in addition, this product need not be installed safety check on water intake, can both realize preventing that the situation that cold water flows backwards from occurring in hot-water line, thereby reach easy for installation, effectively lower the purpose of product cost; And this switch spool is arranged on the water inlet of the hot-water line of tap, it is the control hot water flow effectively, when carrying out the tap maintenance, need only just can prevent effectively that hot water from entering faucet subject by the off switch spool, guaranteed the maintenance safety of product, this product also has governing speed and soon, had both made things convenient for justice to reduce the waste of water resources in the temperature adjustment process, the characteristics that water-saving result is good, thus can be widely used in constant-temperature tap on the solar water heater.
