Description
Technical Field
The invention relates to the technical field of bathroom faucets, in particular to a ceramic valve plate assembly of a switch valve core and the switch valve core provided with the same.
Background
The constant temperature faucet is a water flow control device commonly used in a bathroom, so that the shower preference of a user is met, and the bathroom is often provided with a top-mounted spray head and a shower head capable of spraying by hand, so that the constant temperature faucet is required to have a double-way water outlet function.
The constant temperature faucet (application number CN 201520658604.5) with double-way water outlet is a constant temperature valve of the structure type. The water inlet of hot water, the water outlet of hot water, the water inlet of mixed water, the water outlet of first gear and the water outlet of second gear of the connecting pipeline are arranged on the static piece of the ceramic valve core, three diversion channels are arranged on the moving piece, and the hand wheel quick-opening assembly rotates the adjusting handle of the ceramic valve core to drive the diversion channels of the moving piece to be matched with the static piece so as to form a water outlet closing state or a first-gear water outlet state or a second-gear water outlet state. The patent improves the problems of complex structure and easy channeling of cold and hot water of the faucet in the prior art, and realizes the double-way water outlet of the faucet.
The cold water inlet channel of the constant temperature tap is directly connected with the constant temperature valve core, hot water and mixed water enter and exit through the ceramic valve core, and the flow is controlled by the ceramic valve core. In the actual use process, when the tap is turned down, the inlet and outlet flow of hot water is reduced, the hot water pressure is also reduced, and the inlet pressure of cold water is kept unchanged because the cold water is directly communicated with the constant temperature valve core, so that the proportion of the cold water pressure and the hot water pressure entering the constant temperature valve core is unbalanced. The constant temperature valve core is used for regulating the constant temperature of the outlet water temperature, has certain requirements on the inlet cold water and hot water, and when the inlet cold water flow is excessive or the inlet hot water flow is excessive, namely the cold water pressure and the hot water pressure are greatly different, the constant temperature of the constant temperature valve core can exceed the constant temperature regulation capacity range of the constant temperature valve core, the constant temperature effect of the constant temperature valve core can be invalid, and the temperature of the outlet mixed water can not be effectively regulated to be at the set comfortable temperature.
The ceramic valve core in the constant-temperature faucet can not regulate and control cold water, the water inlet pressure of the cold water is relatively constant, mixed water is in an outflow state, and the outlet pressure is smaller than the water inlet pressure of the cold water and the hot water. In the use, under the condition that the original water pressure is kept in cold water, the hot water pressure is unstable because of manual adjustment, and the proportion of cold water pressure and hot water pressure is unbalanced, and when unbalance reaches a certain degree, the regulation bearing range of mixing valve core will be exceeded, causes the inefficacy waste of thermostatic valve core. Excessive cold water flows out from the mixing water gap (a small amount of cold water can flow along the hot water channel), so that mixed water becomes cold, and mixed water outlet is unstable, and the use comfort of the faucet is affected.
