Embodiment
With reference to Fig. 1, Fig. 2, the temperature-sensitive moving valve core of the utility model thermostatic valve, comprise the slide block 20 that can in the constant temperature valve core body, slide, slide block circumferentially has osculum 24, and there is counterbore 25 at the slide block center, counterbore one end welding inductive rod 3, the other end valve rod base 7 that has been threaded, between valve rod base 7 bottom surfaces and counterbore 25 bottom surfaces plane glue 22 is housed, total is simple, convenient processing and manufacture; Heat sensitive material 26 is packed in the blind hole of inductive rod 3, can suitably control consumption as required; The valve rod 9 that can slide along the hole is housed in the through hole 27 of valve rod base.
In the present embodiment, inductive rod 3 adopts the red copper material, its receptance to temperature is strong, the outer surface of inductive rod has the many places projection that is spline shape, six blind holes are arranged in it, and corresponding one by one with the distributing position of spline shape projection, such structure can effectively increase contact and heat diffusion area, makes the induction of rod sensitive more; Spline shape projection can also play the effect of strengthening barred body, and barred body can not be out of shape when expanding with heat and contract with cold when its inner heat sensitive material varies with temperature.
Between plane glue 22 in valve rod base through hole 27 and the valve rod 9 cylinder glue 21 is housed also, prevents valve rod bad plane, the top glue in the process that slidably reciprocates, then whole spool is more reliable, durable.The groove of slide block outer wall is used to install seal ring, plays seal action when slide block is installed on the Inductance valve inwall.
With reference to Fig. 3～Fig. 7, the utility model is applied to the structural representation in the constant temperature valve core.Each part name of this constant temperature valve core is respectively: 1, overlap 2 behind the spool, overlap 19 in the spring 3, inductive rod 4, four forks 5, seal ring 6, valve rod pad 7, valve rod base 8, seal ring 9, valve rod 10, hexagon nut 11, hexagonal cover 12, seal ring 13, snap ring 14, screw rod 15, hex head bolt 16, spring 17, copper packing 18, spool, seal ring 20, slide block 21, cylinder glue 22, plane glue 23, seal ring.
During use, regulate temperature as required earlier: by turn screw rod 14, regulate the size of hot water or cold water's water intake, make temperature reach predetermined value.In working order down, the hot water inlet that hot water overlaps in spool flows into, and the osculum 24 on slide block 20 enters mixing chamber, and cold water then enters mixing chamber by the cold water inlet that overlaps in the spool, thereby the water temperature of inductive rod 3 induction mixing chambers is in time reacted.When the water-mixing temperature in entering valve core is higher than predetermined temperature, heat sensitive material expanded by heating in the inductive rod, give plane glue 22, cylinder glue 21, valve rod 9 certain pressures, and at the other end of valve rod, copper packing 17 withstands valve rod under the effect of spring 16, like this, under reaction force, valve rod 9 promotes slide block 20 and overlap slip in 18 in spool, and the hot water mouth reduced when then cold water outlet became Datong District, and mixed coolant-temperature gage descends; When the mixing water temperature in entering valve body is lower than predetermined temperature, heat sensitive material in the inductive rod is met cold contraction, and spring 2 has overcome the active force of 16 pairs of valve rods 9 of spring, promotes slide block 20 and slides to the cold water outlet direction, then cold water outlet diminishes simultaneously that the hot water mouth increases, and the temperature of mixing water improves.
This temperature-sensitive moving valve core expanding with heat and contract with cold by heat sensitive material in the inductive rod, the water temperature that spool is caused extraneous factors such as water pressure fluctuations changes in time reacts, in constant temperature valve core, slide, thereby change the size of constant temperature valve core water inlet and water outlet, reach the purpose of balancing water temperature.Because the contact and the heat diffusion area of inductive rod are big, be quick on the draw, again because the mobile size that can change cold water inlet and hot water inlet simultaneously of induction moving valve core, make that the temperature regulation speed of whole spool is fast, can reach required state of temperature rapidly, make the water temperature of mixing water maintain the temperature value that sets all the time, realize the effect of automatic constant-temperature, improved the travelling comfort and the Security of bathing greatly.
Induction moving valve core of the present utility model can also be used in the constant temperature valve core of other structures.
