Description

Thermostatic spool

technical field

The invention relates to a valve core, in particular to a special thermostatic valve core for a thermostatic faucet which can keep the water temperature constant and stable.

Background technique

At present, the thermostatic valve cores of existing solar water heaters, electric water heaters, and boilers have a certain effect of maintaining water temperature, but they also have many shortcomings:

1. The main disadvantage is that the control of water temperature is not stable enough. For example, when the water pressure is unstable, the temperature changes, so that the outlet water temperature cannot reach the set temperature; or when the hot water temperature is unstable, the water temperature cannot reach the set temperature, resulting in intermittent cold and hot phenomena. When the user uses the water heater to bathe or the boiler to bathe, the water temperature cannot be kept stable, which brings inconvenience to the user. Moreover, when the user uses the solar water heater to take a bath, one of the two water supply pipelines is a solar hot water channel, and the other is a tap water channel. When the tap water is cut off, the solar hot water channel cannot be stopped in time. Only releasing hot water can easily cause serious consequences of scalding people.

2. Ordinary faucets have not been used for a long time or due to water quality reasons. When using ordinary thermostatic faucets, it is easy to emit peculiar smell while draining water.

3. The size of the filter in the ordinary thermostatic faucet is small, and the filtering effect is poor. If the water quality is poor or the water contains sediment, scale and other factors, it is easy to cause the faucet to be blocked, and it is easy to reduce the service life of the thermostatic faucet. In severe cases, it will lead to constant temperature failure and other conditions.

4. Ordinary constant temperature faucets are prone to breed bacteria due to long-term use or poor water quality. When used in bathing or other situations, it is easy to cause discomfort to the human body, and it is easy to cause skin diseases such as skin itching and rashes.

5. When the ordinary thermostatic valve core and the faucet are joined together, the faucet shell needs to be formed through a sand-foundry process. Because the sand-foundry process is likely to bring certain pollution to the environment, it is not conducive to environmental protection.

Therefore, there is an urgent need for a thermostatic spool with anti-scald, deodorant, anti-clogging, sterilizing, and environmental protection functions in the market, so as to satisfy the demand in the thermostatic faucet market.

Detailed ways

As shown in Figures 1 to 5, the thermostatic valve core of the present invention includes a valve core body, a first waterway guide 18, a second waterway guide 21 and a regulating switch 24 connected in sequence. A plurality of heat insulating sleeves 28, 30, 32, 34 are respectively provided on the outside of the core body, the first waterway director 18 and the second waterway director 21, and the first waterway director 18 and the second waterway director The two waterway guides 21 cooperate, and the first waterway director 18 and the second waterway guider 21 protrude and meet to form a joint 100 with a connected hollow cavity. A hot water channel 101 is formed between 100 and the heat insulating sleeve 30, and the hot water channel 101 communicates with the hot water inlet; the hollow cavity of the joint part 100 forms a hollow water mixing channel 102, so The water mixing channel 102 is in communication with the water outlet, a first filter 38 is provided in the hot water channel, and a second filter 40 is provided in the water mixing channel. Wherein, the valve core body includes a regulator 1, a wear-resistant washer 2, an adjusting nut 3, a hexagonal regulator 6, a valve core upper body 36, a first spring 5, a heat-sensitive element 14, and a piston disc 10 connected in sequence. , the second spring 16 and the main body 15 of the spool. O-rings 22, 42 are provided between the first waterway director 18, the second waterway director 21 and the heat insulation sleeves 28, 30, so that the second waterway director 21 and the A vacuum layer is formed between the heat insulation sleeves; O-rings 8, 13, 20, 23, 27 and faucet housings are arranged between the valve core body and the heat insulation sleeves 32, 34, so that A vacuum layer is formed between the valve core body and the heat insulating sleeve. In this way, a double vacuum is formed, which has a good heat insulation and anti-scald function. When the temperature of the hot water is around 80°, the surface temperature of the faucet will also be close to 75°. Caution Risk of burns when touching the surface of the thermostat. The thermostatic valve core of the present invention has a unique double-vacuum design, and when hot water passes through the thermostatic valve core, it is vacuum separated from the heat-insulating sleeve to achieve a good anti-scald effect.

As shown in Figure 2, one side of the first waterway director 18 is a disc body 103, and a hollow columnar first connecting portion 104 protrudes from the disc body 103 to one side.

This device can play the role of filtration, sterilization and disinfection, and remove the peculiar smell in the water to achieve the effect of deodorization. The constant temperature valve core of the present invention is equipped with multi-layer large-area filter nets, which can achieve a long-term large-area filter effect, can prolong the service life well, and help users relieve the worries caused by blockage. The inner diameter of the section of the cylindrical filter body is 17mm-19mm, the outer diameter is 33mm-35mm, and the length is 68mm-70mm. The priority is that the inner diameter of the section is 18mm, the outer diameter is 34mm, and the length is 68mm, which can have a good filtering effect and greatly prolong the service life of the faucet. The thermostatic valve core of the present invention passes through most of the area of the entire valve core with high-temperature water and the nano-activated carbon technology device, and this double setting can well achieve the effects of sterilization and disinfection. When the button is turned to the high-temperature disinfection area, the cold water is turned off, and the high-temperature hot water runs through the entire faucet from the hot water inlet, and finally flows out from the water outlet, so that the high-temperature sterilization effect is remarkable. In addition, the valve core is equipped with double-layer nano The activated carbon device plays a better role in sterilization.

The material used for the spool body is environmentally friendly copper material. The thermostatic valve core only needs one copper pipe, one water outlet and two water inlets to form the main body of the thermostatic faucet, while the ordinary faucet shell basically needs to be formed through the sanding process. The faucet shell matched with the thermostatic valve core of the present invention The body is directly formed by the copper tube as a whole, which greatly reduces the environmental pollution caused by the foundry process and can better protect the environment.

The invention relates to a constant temperature valve core regulator. The regulator 1 and the hexagonal regulator 6 form a regulating hexagonal device, the regulating hexagonal device is connected with the upper body 36 of the spool, and the lower part of the regulating hexagonal device pushes against the piston rod on the thermosensitive element 14, and the thermosensitive element 14 is connected with the piston disc 10, and then It is connected with the large spring 16, and when the regulator is turned, it can regulate the temperature. The valve core upper body 36 is connected with the valve core main body 15 to form a valve core, and the valve core main body 15 is connected with the lower port of the heat insulator and the water channel leading filter 18, so as to separate the water channel. The nano activated carbon 39 is packed into the filter screen 38, the nano activated carbon 41 is loaded into the filter screen 40, and then the water channel guide 18 and the water channel guide 21 are connected to play the role of filtration, sterilization and disinfection. The waterway director and the heat insulator are connected through the O-ring 22 and the O-ring 42 to form a vacuum effect. The switch 24 is connected to the switch base 25 and connected to the waterway director 21 to switch and mix the water. The whole set The valve core forms another vacuum effect through the O-ring 8 , O-ring 13 , O-ring 20 , O-ring 23 and O-ring 27 and the heat insulator and the faucet housing.
