Description

A new type of constant temperature faucet

technical field

The utility model relates to a faucet, in particular to a novel constant temperature faucet.

Background technique

Existing ordinary thermostatic faucets use a single-control quick-open valve core installed in the mixing water channel to control the flow, which can only close the mixed water, and cannot separately close the cold water and hot water. Collusion, a check valve must be installed, but the thermostatic faucet with a check valve has the following defects in use:

1) The opening of the check valve requires a certain water pressure, which is particularly restricted in the drop-type solar water heater, so that the hot water cannot be normally input and mixed with cold water;

2) When the internal scale or sundries are deposited in the thermostatic faucet and the pressure difference between the two ends of the check valve is small, its sealing performance will be reduced, which will easily cause mixed flow of cold and hot water, resulting in confusion of the hot and cold water supply pipe network, affecting the normal water consumption of users;

3) For thermostatic faucets that require two water outlets (such as bathtub and shower outlets), it is necessary to add a reversing valve in the faucet, which will cause inconvenience in use, increase cost, and affect the appearance;

4) Existing thermostatic faucets connected to solar water heaters need to use multifunctional curved legs in order to match the structure of solar water heaters, which not only increases the cost of the thermostatic faucet, but also affects its appearance.

In order to overcome the above-mentioned shortcoming, the inventor specially developed a novel thermostatic faucet, and this case arose from it.

The cold water inlet 15 of the valve body 1 is provided with a throttle valve 151. The throttle valve 151 can throttle the cold water circuit. When the hot water pressure is low, the cold water flow rate is reduced to make it close to the hot water pressure (flow rate). In this way, the thermostatic faucet can be avoided from being hot and cold when the pressure difference between the hot and cold water is too large.

The utility model has the following working states:

1. When the waterway needs to be closed, turn the switch handwheel 5 to drive the waterway control valve core 3 to rotate, so that the upper water outlet hole 34 is staggered from the upper water outlet channel 162, the lower water outlet hole 35 is staggered from the lower water outlet channel 163, and the hot water inlet channel 141 is at the same time Staggered with the hot water inlet 31, the hot water outlet hole 32 and the hot water outlet channel 142 are staggered, the waterway is completely closed, and the hot water no longer flows to the temperature control valve core 2, so that the mixed flow of cold water and hot water will not occur.

2. When it is necessary to realize the water outlet from the upper water outlet 171, turn the switch handwheel 5 to drive the water control valve core 3 to rotate, so that the upper water outlet hole 34 is connected with the upper water outlet channel 162, and the hot water inlet channel 141 is connected with the hot water inlet 31 at the same time. The hot water outlet hole 32 communicates with the hot water outlet channel 142, the hot water flows to the temperature control valve core 2 after passing through the water channel control valve core 3, and the cold water enters the temperature control valve core 2 through the cold water inlet 15 of the valve body 1 and the cold water inlet 21 of the temperature control valve core 2. Control spool 2, hot water and cold water are mixed and flow out from the mixing outlet 23 of the temperature control spool, and flow to the waterway control spool 3 again through the mixed water inlet channel 161, and finally pass through the upper water outlet hole 34 and the upper water outlet channel 162 And the water outlet 171 on the valve body flows out.

3. When it is necessary to realize the water outlet from the lower water outlet 172, turn the switch handwheel 5 to drive the waterway control valve core 3 to rotate, so that the lower water outlet hole 35 communicates with the lower water outlet channel 163, and at the same time the hot water inlet channel 141 communicates with the hot water inlet 31. The hot water outlet hole 32 communicates with the hot water outlet channel 142, the hot water flows to the temperature control valve core 2 after passing through the water channel control valve core 3, and the cold water enters the temperature control valve core 2 through the cold water inlet 15 of the valve body 1 and the cold water inlet 21 of the temperature control valve core 2. Control spool 2, hot water and cold water are mixed and flow out from the mixing outlet 23 of the temperature control spool, and flow to the water control spool 3 again through the mixed water inlet channel 161, and finally pass through the lower water outlet hole 35 and the lower water outlet channel 163 And the water outlet 172 under the valve body flows out.

The utility model only realizes the on/off control of mixed water and hot water or mixed water and cold water by setting a waterway control valve core 3 with multiple water inlet and outlet holes, and cooperating with the corresponding water inlet and outlet channels on the valve body 1. The unique check valve can prevent problems such as mixed flow of hot and cold water, and can realize two-way water outlets from the temperature-controlled faucet without using a water separator. Therefore, the utility model is more convenient to use, simpler in structure, and relatively lower in cost.

The utility model does not need to adopt components such as check valves and multifunctional curved feet, so when used in conjunction with solar water heaters, the cold water will not eject the hot water in the water heater due to excessive water pressure; in addition, users can choose according to needs The water comes out from the upper or lower road. When it is used for bathing faucets, the upper road can be sprayed on the top, and the lower road can be connected to the shower.
