The spherical valve core (4) is driven by the handle (5) to do front and rear, left and right rotation, which alters the relative positions between the two end ports of a channel (3) and water inlet ways (14, 15) and a water outlet way (13), and simultaneously regulates water temperature and water flow. The utility model has the advantages of simple structure and good sealing performance; the cold-hot water mixing valve overcomes the defects of the existing mixing valve of a plurality of means, easy damage, and hot and cold water channelling; the cold-hot water mixing valve is suitable for various bath places.

Description

Cold-hot water mixing valve

The utility model relates to a kind of water mixing valve that is used for bathing place energy while control water temperature and flow.

Water mixing valve claims to mix water nozzle again, regulates water temperature and water flow with a handle, and is easy to use.Be used for the bathing place, particularly the hotel bathing chamber receives an acclaim day by day.Existing water mixing valve, it as the patent No. 89219889.3 mixing valve, form by handle, valve rod, valve gap, valve body, inner plunger, the column sleeve structure of adopting, part number is many in the valve, and matching gap requires high, and needs pairing break-in, fault is many during use, maintenance difficult, and also have a defective that is difficult to overcome: current are scurried mutually between the two-way inlet channel.

Task of the present utility model provides a kind of water mixing valve, and it has simple in structure, makes easily, can channelling between water channel, and characteristics such as operational failure is few, and is easy to maintenance.

For solving above-mentioned task, scheme of the present utility model is: the water mixing valve of being made up of handle, valve rod, valve gap, valve body, it is characterized in that valve gap and valve body surround a spherical cavity, the spool of the built-in sphere in chamber, spool is connected with handle by valve rod, and be provided with a passage, and a port of passage is corresponding with two inlet channels on the valve body, and another port is corresponding with the water outlet on the valve body.Handle is handled spool by valve rod and is all around rotated, the relative position into and out of water channel on two ports that change the spool upper channel and the valve body, adjusting water temperature and water flow.

Such scheme has significantly reduced the member in the valve, makes that making is quite easy, and cost also decreases, and has also reduced rate of breakdown certainly.Between valve gap and spool, between valve gap and the valve body, between spool and two inlet channels, settle four O-ring seals between spool and the water outlet respectively.Tighten the screw thread between valve gap and valve body, can easily each seal ring be compressed, reach sealing purpose.The water of scurrying between two inlet channels also solves thereupon.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is a structure centre sectional view of the present utility model.

Fig. 2 is the plan view of valve gap.

Fig. 3 is the dextrad intake pipe central cross-sectional view of valve body.

Fig. 4 is the worm's eye view at two inlet channel positions.

Embodiment as shown in Figure 1, by the water mixing valve that handle 5, valve rod 6, valve gap 9, valve body 1 are constituted, valve gap 9 surrounds a spherical cavity, the built-in spherical valve core 4 in chamber with valve body 1.One side of valve body 1 has a water outlet 13, is commonly referred to water nozzle, the bottom be one by two adjacent semicircle inlet channels 14 and the 15 conjuncted pipes that form.A square deep hole is arranged at spool 4 tops.A rectangular guiding groove 8 is arranged at valve gap 9 tops.The guiding groove 8 that has outstanding shirt rim 7, valve rod 6 tops to pass valve gap 9 in the middle of the valve rod is connected with handle 5, and the bottom is the cuboid that matches mutually with the square deep hole of spool 4, and this cuboid just is inserted in the square deep hole.Two passages 3 that the circular holes perforation forms that are the man type intersection by central axis are arranged at the bottom of spool 4.The water inlet port of passage 3 is corresponding with two inlet channels 14 and 15 of valve body 1, and the water outlet port is corresponding with the water outlet 13 of valve body 1.O-ring seals 10 of peace between valve gap 9 and the spool 4, O-ring seals 11 of peace is pacified an O-ring seals 12 between valve gap 9 and the valve body 1 between spool 4 and the water outlet 13, pacifies an O-ring seals 2 between spool 4 and two inlet channels 14 and 15.Tighten the connecting thread between valve gap 9 and the valve body 1, just can compress each seal ring.

When handle 5 drives spools 4 and makes left rotation and right rotation by valve rod 6, misplace about two inlet channels 14 of the water inlet port of the passage 3 of spool 4 and valve body 1 and 15 take place, close until an inlet channel, another inlet channel is unimpeded fully.Otherwise it is then opposite.And the water outlet 13 of the water outlet port of passage 3 and valve body 1 keeps unimpeded.Realize that thus regulating the two-way flow of inlet water is the function of temperature adjustment.Pass through of guiding groove 8 slips of the shirt rim 7 of valve rod 6 along valve gap 9 when handle 5, when rotating before and after drive spool 4 is done, dislocation takes place up and down in the water outlet 13 of the water inlet port of passage 3 and the inlet channel 14 and 15 of valve body 1, water outlet port and valve body 1 simultaneously, makes latus rectum become big or diminishes, until closing fully.Realize regulating the function of water flow thus.

Hold conveniently for making, handle 5 adopts the handwheel shape.
