Description
Technical Field
The invention relates to a thermostatic valve, in particular to a thermostatic valve with a rapid water feeding function.
Background
A constant temperature valve, commonly called as a constant temperature faucet, is a common water heater shower faucet in the market, and has the following basic structure and working principle: the constant temperature valve element and the switch valve element are arranged on a valve body, a cold water inlet hole, a hot water inlet hole, a cold water outlet hole, a hot water outlet hole and a constant temperature water outlet are arranged, cold water in a water tower or a public water supply system and hot water in a water heater respectively flow into the switch valve element from the cold water inlet hole and the hot water inlet hole, flow out from the cold water outlet hole and the hot water outlet hole after being controlled by the switch valve element, and flow into the constant temperature valve element through a cold water channel and a hot water channel respectively, and cold water and hot water are mixed in the constant temperature valve element and flow out from the constant temperature water outlet hole after being subjected to constant temperature regulation; when external cold and hot water flows through the switch valve core, the switch valve core can realize the following functions: 1. the closing function of the thermostatic valve is realized by closing the communication of the cold water inlet hole and the cold water outlet hole and closing the communication of the hot water inlet hole and the hot water outlet hole simultaneously; 2. the opening or flow regulation function of the thermostatic valve is realized by simultaneously opening the communication between the cold water inlet hole and the cold water outlet hole and opening the communication between the hot water inlet hole and the hot water outlet hole; 3. the water supply function of the water heater is realized by opening the communication between the cold water inlet hole and the hot water inlet hole.
A multi-function mixing faucet, such as that disclosed in chinese patent application No. 200920316190.2, is a thermostatic valve of this type of construction. However, this type of construction of thermostatic valve is subject to the following two conditions during practical use: 1. the thermostatic valve core regulates the constant temperature of the outlet water, certain requirements are provided for the entering cold water and hot water, when the temperature change of the cold water and the hot water is not large, the flow of the entering cold water is too much or the flow of the hot water is too much, the capacity range of the thermostatic valve core for thermostatic regulation is exceeded, the thermostatic action of the thermostatic valve core is invalid, namely, the temperature of the flowing mixed water can not be effectively regulated to be at the set comfortable temperature; 2. the excessive cold water or the excessive hot water, i.e., the excessive flow rate of the cold water or the hot water, is related to the product of the pressure of the water and the water passing area (flow passage size). In actual use, the pressure ratio of cold water pressure to hot water pressure of different families often has a bigger difference, and after the same thermostatic valve is made into a product, the sizes of the cold water flow passage and the hot water flow passage are determined, so that the thermostatic valve is easy to cause the thermostatic action failure of the thermostatic valve core when the thermostatic valve is used in different families.
For the above problems, the common solution adopted by the thermostatic valve of this type sold in the market at present is to arrange a flow regulating device at the cold and hot water inlet holes of the external cold and hot water pipelines or the valve body, and regulate and control the flow of the cold and hot water by regulating and controlling the water passing area of the flow passage, so that the flow of the cold and hot water mixed in the thermostatic valve core is suitable for the application range of the thermostatic valve core.
The above-mentioned way of solving the cold and hot water flow yields the following problems: 1. in actual life, in order to save hot water, the flow of hot water and cold water mixed with the hot water is often very small, and the flow of the regulated cold water and the flow of the regulated hot water are naturally also very small; the flow channel area of the water inlet channel of the cold water and the hot water is regulated and controlled before the cold water and the hot water flow through the switch valve core, the water inlet channel is a water channel when the thermostatic valve is used for discharging thermostatic water and is also a water feeding channel of the water heater, so that the flow of the thermostatic valve for feeding water to the water heater is correspondingly reduced, namely the water feeding efficiency is reduced; 2. the structure setting scheme of the above solution mode supplements and increases functional components on the basis of the original structure, complicates the structure of the thermostatic valve, increases the manufacturing cost, and can cause inconvenient installation of the thermostatic valve and lack of attractiveness in the overall design.

The flow regulating rod 9 is arranged in the thermostatic valve core cold water inlet passage 10 and the thermostatic valve core hot water inlet passage 11 through the thermostatic valve core cold water inlet passage opening 28 and the thermostatic valve core hot water inlet passage opening 29.
As shown in fig. 3, 4 and 5, the bottom of the switch valve core cavity 4 is provided with a switch valve core cold water inlet hole 12, a switch valve core hot water inlet hole 13, a switch valve core cold water outlet hole 14 and a switch valve core hot water outlet hole 15. In this embodiment, the switch valve core cold water inlet hole 12 and the switch valve core hot water inlet hole 13 are located at adjacent positions and off-diagonal positions, and the switch valve core hot water inlet hole 13 and the switch valve core hot water outlet hole 15 are also located at adjacent positions and off-diagonal positions; according to the difference of the switch valve core 2 in actual use, the switch valve core cold water inlet hole 12 and the switch valve core hot water inlet hole 13 can be set to be in a diagonal position relation, and meanwhile, the switch valve core cold water outlet hole 14 and the switch valve core hot water outlet hole 15 are also in a diagonal position relation. The side wall of the thermostatic valve core cavity 4 is provided with a thermostatic valve core cold water inlet 16, a thermostatic valve core hot water inlet 17 and a thermostatic water outlet 18. The switch valve core cold water inlet hole 12 and the switch valve core hot water inlet hole 13 are respectively connected with a cold water source and a water heater outside the thermostatic valve through a valve body cold water inlet hole 19 and a valve body hot water inlet hole 20, and the switch valve core cold water outlet hole 14 and the switch valve core hot water outlet hole 15 are communicated with a thermostatic valve core cold water inlet 16 and a thermostatic valve core hot water inlet 17 on the side wall of the thermostatic valve core cavity 5 through a thermostatic valve core cold water inlet channel 10 and a thermostatic valve core hot water inlet channel 11.
As shown in fig. 6, the bottom of the switch valve core 2 has four valve core stator guide holes 21, which can be respectively communicated with the switch valve core cold water inlet hole 12, the switch valve core hot water inlet hole 13, the switch valve core cold water outlet hole 14 and the switch valve core hot water outlet hole 15 at the bottom of the switch valve core cavity 4.
The basic working principle is as follows:
1. during the user state, rotary switch case 2 can communicate switch case cold water inlet opening 12, switch case cold water apopore 14 and switch case hot water inlet opening 13, switch case hot water apopore 15 respectively. Cold water sequentially passes through the valve body cold water inlet hole 19 and the switch valve core cold water inlet hole 12 from an external cold water source, enters the switch valve core 2 through the valve core stator guide hole 21 corresponding to the switch valve core cold water inlet hole 12, flows out of the adjacent valve core stator guide hole 21 corresponding to the switch valve core cold water outlet hole 14 after the conduction control of the switch valve core 2, enters the switch valve core cold water outlet hole 14, enters the thermostatic valve core cold water inlet 16 on the side wall of the large thermostatic valve core cavity 5 through the thermostatic valve core cold water inlet channel 10, and enters the thermostatic valve core 3 to participate in the mixing temperature regulation with hot water, and the cold water channel is a cold water passage channel when the thermostatic valve is used. Hot water in the water heater enters the thermostatic valve core 3 through a similar hot water passage channel similarly. The constant temperature water after constant temperature mixing flows out from the constant temperature water outlet hole 18.
2. When the valve is closed, the valve core 2 is rotated to respectively close the communication of the cold water inlet hole 12 and the cold water outlet hole 14 of the valve core and the communication of the hot water inlet hole 13 and the hot water outlet hole 15 of the valve core. The external cold water and hot water can not enter the thermostatic valve element 3 through the switch valve element cold water outlet hole 14, the switch valve element hot water outlet hole 15, the thermostatic valve element cold water inlet channel 10 and the thermostatic valve element hot water inlet channel 11, and the closing function of the thermostatic valve is realized.
3. When the water is in the water feeding state, the switch valve core 2 is rotated to disconnect the communication of the switch valve core cold water inlet hole 12 and the switch valve core cold water outlet hole 14 and the communication of the switch valve core hot water inlet hole 13 and the switch valve core hot water outlet hole 15, and the communication of the switch valve core cold water inlet hole 12 and the switch valve core hot water inlet hole 13 is opened. At the moment, under the action of pressure, cold water flows into the water heater through the valve body cold water inlet hole 19, the switch valve core cold water inlet hole 12 and the switch valve core hot water inlet hole 13 after being conducted and controlled by the switch valve core 2, and the water feeding function of the water heater is realized.
The difference between the embodiment of the invention and the prior art is as follows:
the prior art adjusts the cold and hot water flow in the following way: before cold water and hot water flow through the switch valve core 2, the flow passage area of the water inlet channel of the cold water and the hot water is regulated and controlled. The water inlet channel is a water channel for the thermostatic valve to output thermostatic water for use and is also a water feeding channel for the water heater, so that the flow of the thermostatic valve for feeding water to the water heater is reduced, and the water feeding efficiency is reduced.
The invention adjusts the cold and hot water flow by arranging the flow adjusting device of the thermostatic valve at the cold water inlet channel 10 and the hot water inlet channel 11 of the thermostatic valve core before the cold and hot water flow through the switch valve core 2 and flow into the thermostatic valve core 3. The design can effectively avoid the influence of the flow regulating device on the water feeding channel of the water heater, so that the water feeding channel is in a full-open state, the water feeding function of the thermostatic valve can be exerted to the maximum efficiency, and the water feeding device has the function of quickly feeding water.

Switch valve core cold water apopore 14, switch valve core hot water apopore 15 perpendicular to the bottom surface of switch valve core chamber 4, its bottom opening in the lateral wall of the cold, hot water inlet channel of thermostatic valve core, form switch valve core cold water apopore opening 22, switch valve core hot water apopore opening 23. The sizes of the switch valve core cold water outlet hole 14 and the switch valve core hot water outlet hole 15 are smaller than or equal to the sizes of the thermostatic valve core cold water inlet channel 10 and the thermostatic valve core hot water inlet channel 11, so that the switch valve core cold water outlet hole opening 22 and the switch valve core hot water outlet hole opening 23 can be conveniently sealed through the flow adjusting rod 9.
According to actual needs, the flow regulating rod 9 can be only arranged in one of the thermostatic valve core cold water inlet channel 10 and the thermostatic valve core hot water inlet channel 11, and at this time, when the other thermostatic valve core hot water inlet channel opening 29 and the thermostatic valve core cold water inlet channel opening 28 are blocked by other parts or the valve core 1 is manufactured, the thermostatic valve core hot water inlet channel opening 29 and the thermostatic valve core cold water inlet channel opening 28 are not left; and a flow adjusting rod 9 can be simultaneously arranged in the cold water inlet channel 10 of the thermostatic valve core and the hot water inlet channel 11 of the thermostatic valve core, so that the adjustment and the use of consumers are facilitated.
As shown in fig. 8, 9, and 10, the flow regulating rod 9 for flow regulation is installed in the thermostatic cartridge cold water inlet passage 10 and the thermostatic cartridge hot water inlet passage 11 through the thermostatic cartridge cold water inlet passage opening 28 and the thermostatic cartridge hot water inlet passage opening 29, the front portion 24 of the flow regulating rod 9 is semicircular, and the rear portion 25 thereof is cylindrical, and can circumferentially rotate in the thermostatic cartridge cold water inlet passage 10 and the thermostatic cartridge hot water inlet passage 11. The outer surfaces of the semicircular ring of the front part 24 and the tail part 25 of the flow adjusting rod 9 are respectively in close contact with the contained thermostatic valve core cold water inlet channel 10 and the thermostatic valve core hot water inlet channel 11, so that the switch valve core cold water outlet opening 22 and the switch valve core hot water outlet opening 23 can be effectively sealed, and cold water and hot water can be prevented from leaking outwards.
As shown in fig. 2, 9 and 10, the tail 25 of the flow regulating rod 9 further has an end 26 exposing the cold water inlet passage 10 of the thermostatic valve core and the hot water inlet passage 11 of the thermostatic valve core, the end 26 has a fan-shaped limiting protrusion 27 protruding laterally outwards, and correspondingly, the openings of the cold water inlet passage 10 of the thermostatic valve core and the hot water inlet passage 11 of the thermostatic valve core are provided with limiting blocks 30 protruding outwards and matched with the protrusions.
