Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
As shown in fig. 1, a water valve according to a preferred embodiment of the present invention includes a valve body 10, a valve core 30, an upper cover 60, and a handle 90.
As shown in fig. 2 to 5, the valve body 10 is provided with a valve core mounting hole 11, a hot water inlet 12, a cold water inlet 13 and a water outlet 14 which are mutually communicated, wherein the valve core mounting hole 11 is cylindrical and is used for mounting the valve core 30, the hot water inlet 12 is communicated with a hot water pipeline and is used for providing hot water, the cold water inlet 13 is communicated with a cold water pipeline and is used for providing cold water, and the water outlet 14 is used for discharging water.
the valve core 30 is integrally cylindrical and comprises a first channel 31, a second channel 32, a third channel 33, a fourth channel 34 and a fifth channel 35 which are communicated with each other, in order to reduce the manufacturing difficulty and save the production cost, the valve core 30 comprises an upper valve core 36 and a lower valve core 37 which are connected with each other, the upper valve core and the lower valve core are connected with each other through a plurality of bolts 38, and the bolts 38 are sunk into the upper valve core 36 and do not protrude out of the upper surface of the upper valve core.
The first channel 31, the second channel 32, the third channel 33, the fourth channel 34 and the fifth channel 35 are all radially arranged along the valve core 30, and are radial, and the channels are arranged to achieve the following four conditions after being rotated: the hot water level is communicated with the hot water inlet 12 and the water outlet 14 only through two channels; the cold water level is communicated with the cold water inlet 13 and the water outlet 14 only through two channels; the three channels are communicated with a hot water inlet 12, a cold water inlet 13 and a water outlet 14; at the stop position, all the channels are not communicated with the hot water inlet 12, the cold water inlet 13 and the water outlet 14. In this embodiment, the hot water inlet 12, the cold water inlet 13 and the water outlet 14 are spaced at 120 degrees in pairs, and 60 degrees are respectively spaced between the first channel 31 and the second channel 32, between the second channel 32 and the third channel 33, between the third channel 33 and the fourth channel 34, and between the fourth channel 34 and the fifth channel 35.
As shown in fig. 2, when the third channel 33 communicates with the water outlet 14, the first channel 31 communicates with the hot water inlet 12, and the fifth channel 35 communicates with the cold water inlet 13, at this time, the warm water mixed with the cold water and the hot water flows out from the water outlet 14, and the warm water level is at this time.
As shown in fig. 3, after the valve core 30 rotates clockwise 60 degrees from the warm water level, the second channel 32 is communicated with the hot water inlet 12, the fourth channel 34 is communicated with the water outlet 14, and at this time, hot water flows out from the water outlet 14, which is the hot water level.
As shown in fig. 4, after the valve core 30 rotates 60 degrees counterclockwise from the warm water level, the fourth channel 34 is communicated with the cold water inlet 13, the second channel 32 is communicated with the water outlet 14, and at this time, cold water flows out from the water outlet 14, which is the cold water level.
As shown in fig. 5, after the valve core 30 rotates 30 degrees counterclockwise from the warm water level, the outer wall of the valve core 30 blocks the hot water inlet 12, the cold water inlet 13 and the water outlet 14, which is the stop position, and it is obvious that the same effect can be achieved by rotating 30 degrees clockwise. All can pass through the interception position when switching between each warm water level, hot water level, cold water level, such advantage lies in, the in-process normal water of switch position can not continuously flow out, can the water economy resource.
The valve core 30 is rotatably connected with the valve core mounting hole 11, and has high matching precision, so that when the outer wall of the valve core 30 blocks the hot water inlet 12 and the cold water inlet 13, a good sealing effect is achieved. And a first sealing ring 15 and a second sealing ring 16 can be arranged on the matching surface between the valve core 30 and the valve body 10, and the first sealing ring 15 and the second sealing ring 16 are respectively positioned at the upper side and the lower side of each channel, so that the matching precision of the valve core 30 and the valve core mounting hole 11 can be reduced, and the sealing effect can be further improved.
referring to fig. 1, an upper cover 60 is attached to an upper surface of the valve body 10 for preventing the valve cartridge 30 from being removed from the valve body 10. The valve core 30 is further provided with a matching part 39 penetrating through the upper cover 60, the handle 90 comprises a seat body 92 and a handle 93, the matching part 39 is matched and connected with a matching hole 91 formed in the lower surface of the seat body 92, and the valve core 30 can be driven to rotate by rotating the handle 90.
For further convenience of use and to avoid the situation shown in fig. 6 where the hot and cold water inlets 13, 12 are connected and water cannot flow out of the water outlet 14, a boss 61 is provided on the upper cover 60, and referring to fig. 1 and 7, the boss 61 is preferably in the form of an open ring having a first end surface 62 and a second end surface 63. A baffle plate 94 is arranged on the side surface of the base body 92, and when the baffle plate 94 rotates to be in contact with the first end surface 62, the baffle plate is in a hot water level, and when the baffle plate 94 rotates to be in contact with the second end surface 63, the baffle plate 94 is in a cold water level, and the rotation range of the baffle plate 94 is limited by the boss 61. In actual use, marks corresponding to the warm water level, the hot water level, the cold water level and the stop position can be arranged on the upper cover 60, so that the use by people is further facilitated.
The cold and hot water valve of the invention at least has the following advantages:
1. The structure is simple, and the use is convenient;
2. Water can not continuously flow out in the process of switching cold water, warm water and hot water, and water resources can be saved.
