The thermostatic valve core is controlled by the thermosensitive element to automatically adjust the mixing proportion of cold water and hot water, so that the outlet water temperature of the mixed water can be automatically kept at a set temperature.
However, the constant temperature faucet is affected by water pressure, the switch valve core is insufficient to control the change of water flow caused by unstable pressure of the cold water and the hot water, when one of the cold water and the hot water stops or the water pressure is too large, the water quantity flowing out of the switch valve core is too small or too large, the flow ratio of the cold water and the hot water entering the constant temperature valve core exceeds the constant temperature regulation capacity range of the constant temperature valve core, the constant temperature effect of the constant temperature valve core is invalid, namely the temperature of the flowing mixed water cannot be effectively regulated to be at a set comfortable temperature, sudden change fluctuation of the water temperature of the supplied mixed water is extremely easy to occur when the change of the water pressure of the cold water and the hot water is large, especially when the water temperature of the supplied mixed water is bathed, a user feels cold or scalded immediately, the body is not suitable, and potential safety hazards exist.
Disclosure of Invention
The invention provides a scheme for solving the problems of temperature regulation failure and unstable water outlet of a constant-temperature valve core caused by unstable water pressure aiming at the problems in the prior art, and particularly provides a main body structure of a constant-temperature faucet with a pressure balance valve.
In order to achieve the above purpose, the present invention adopts the following technical scheme.

Therefore, the main body structure of the constant-temperature faucet has the effects of opening and closing the valve core, preventing scalding and cold of the pressure balance valve and automatically balancing cold and hot water pressure, automatically adjusting the temperature of the constant-temperature valve core and leading to constant-temperature water outlet, and the use feeling of a user is better and safer. Meanwhile, the existence of the pressure balance valve ensures that the constant temperature valve core is always in a normal working environment and cannot exceed the practical range of pressure/water quantity, so that the service life of the constant temperature valve core is prolonged.
The pressure balance valve is a common technology and generally comprises a fixed outer sleeve and a sliding inner sleeve, and the inner sleeve can slide in the outer sleeve by utilizing the water pressure difference of cold water and hot water, so that the water yield of a high water pressure end is reduced, and the effect of stabilizing the water temperature can be achieved. However, the materials of the existing pressure balance valves are generally plastics, copper or ceramics, and the pressure balance valves made of the above structures or materials have the following problems: 1. the copper material is easy to oxidize in water, so that the inner sleeve is blocked and resistant to movement, and the pressure balance valve is aged too early, so that the service life is not long; 2. after the plastic material is immersed for a long time, the plastic material is easy to expand and age, so that the friction resistance is increased, the pressure balance valve is easy to fail, and the service life is not long; 3. the ceramic material has high brittleness, low impact resistance, easy processing in later period, low processing yield and high product cost. The sliding resistance of the existing pressure balance valve is gradually increased under the influence of materials, so that the pressure regulating speed is slow, and if the existing pressure balance valve is not used for a long time, the idle outer sleeve and the idle inner sleeve are easy to be blocked due to rust/aging, so that the pressure balance valve is insufficient in durability. The ceramic pressure balance valve is obviously high in manufacturing cost and fragile, and the living cost of a user is increased.

The stainless steel is not easy to generate corrosion, pitting corrosion, rust or abrasion, the defects of easy scale generation and easy aging of copper and plastic are avoided, and the service life of the pressure balance valve is greatly prolonged; the stainless steel is not fragile, has good ductility and is easy to process, the production cost is reduced by at least 1/2 compared with that of ceramic, but the material property is not weaker than that of ceramic, and the practical value is higher; in addition, the stainless steel has lower heat conductivity, is less prone to heat transfer compared with copper and ceramic, is placed in a valve body of the faucet, is not prone to scalding hands of the faucet due to hot water circulation, and has higher safety performance. The surface finish of the outer sleeve and the inner sleeve which are made of stainless steel are very high after polishing treatment, so that the sliding resistance of the inner sleeve in the outer sleeve is reduced, and the accuracy of balance pressure regulation is improved; the gap between the outer sleeve and the inner sleeve is not more than 2 wires, so that the water flow is in a tight contact state, water can not flow between the outer sleeve and the inner sleeve basically, fine sand and stones falling into the gap can be ground along with the sliding of the inner sleeve due to the high hardness of the water flow, and the smoothness of the sliding process of the inner sleeve is ensured. The pressure balance valve using stainless steel as the material has the advantages of long service life, high safety performance, low production cost, smooth sliding of the inner sleeve, difficult blocking and the like, can reduce the number of times of replacement of users, and saves the living cost.
