AI Technical Summary

Problems solved by technology

However, after the existing thermostatic faucet is disassembled, the circumferential position of the thermostatic valve core will change due to the deviation of the tightening torque when the thermostatic valve core is reinstalled.
At the same time, when the thermostat handwheel is reinstalled, the relative position of the thermostat handwheel and the thermostat valve stem will also change, which will cause the outlet water temperature of the thermostatic faucet to not correspond to the outlet water temperature indicated by the indicator arrow, which will affect the use

Embodiment 1

[0061] Embodiment 1, a thermostatic faucet that is easy to disassemble the thermostatic valve core,

[0062] Such as figure 1 As shown, a thermostatic faucet that is easy to disassemble the thermostatic valve core includes a housing 1. A long valve body 2 is installed in the housing 1. The left end of the valve body 2 is provided with a switch valve core chamber 29, and the right end of the valve body 2 is provided with a There is a thermostatic spool chamber 3, a switch spool 30 is installed in the switch spool chamber 29, and a thermostatic spool 4 is installed in the thermostatic spool chamber 3. A switch valve rod is stretched out from the end of the switch valve core 30, and a switch handwheel is fixedly installed on the switch valve rod. A thermostatic valve stem 5 protrudes from the outer end of the thermostatic valve core 4 . A thermostatic handwheel 6 is fixed on the thermostatic valve stem 5, and a pressure sleeve 7 is arranged between the thermostatic handwheel 6 ...

Embodiment 2

[0069] Embodiment 2, a thermostatic faucet that is easy to disassemble and wash the thermostatic valve core

[0070] The difference between embodiment two and embodiment one is that the thermostatic valve core 4 in embodiment two is as Figure 8 As shown, the temperature sensing element is a memory alloy spring 21, the memory alloy spring 21 is installed on the left side of the piston 22, and the return spring 18 is installed on the right side of the piston 22. The water inlet close to the temperature regulating valve stem 5 on the valve housing 14 is a hot water inlet 46, which communicates with hot water, and the water inlet far away from the temperature regulating valve stem 5 on the valve housing 14 is a cold water inlet 45, which communicates with cold water.

[0071] During use, the water inlet two 33 on the right half 28 is communicated with the hot water supply pipeline, and the water inlet one 31 on the left half 27 is communicated with the cold water supply pipeline....

Embodiment 3

[0072] Embodiment 3, a thermostatic faucet that is easy to disassemble and wash the thermostatic valve core

[0073] Such as Figure 9 As shown, the difference between the third embodiment and the second embodiment is that the current limiting assembly 19 of the third embodiment adopts a double sliding sleeve assembly 25 . The inside of the hot water inlet 46 and the cold water inlet 45 of the valve casing 14 is equipped with a double sliding sleeve assembly 25. The double sliding sleeve assembly 25 includes an outer sleeve 48 and an inner sleeve 49. The jacket 48 is provided with a water control port one 51 and a water control port two 52, and the water control port one 51 and the water control port two 52 communicate with the hot water inlet 46 and the cold water inlet 45 respectively. Corresponding to the first water control port 51 and the second water control port 52, the inner sleeve 49 is provided with a water control port three 53 and a water control port four 54. Th...

Abstract

The invention discloses a constant temperature faucet capable of conveniently detaching and cleaning a constant temperature valve element. The constant temperature faucet comprises a shell, wherein avalve body is mounted in the shell; a constant temperature valve element cavity is formed in one end of the valve body; the constant temperature valve element is mounted in the constant temperature valve element cavity; a temperature adjusting valve rod stretches out of the external end of the constant temperature valve element; a temperature adjusting hand wheel is fixed on the temperature adjusting valve rod; a pressing sleeve is arranged between the constant temperature valve element and the temperature adjusting hand wheel in a sleeving manner; the inner end face of the pressing sleeve ispositioned on the outer side of the radial surface of the constant temperature valve element and is propped against and compresses the radial surface; a thread connected with the inner wall of the constant temperature valve element cavity is formed in the peripheral surface of the inner end of the pressing sleeve; a clamping part is arranged on the side face at the external end of the pressing sleeve; and the clamping part is positioned between the shell and the temperature adjusting hand wheel. The constant temperature faucet is more convenient to maintain and can detach the constant temperature valve element from the valve body to be cleaned without detaching the temperature adjusting hand wheel.

Description

technical field [0001] The invention relates to sanitary equipment, in particular to a thermostatic faucet which is easy to disassemble and wash a thermostatic valve core. Background technique [0002] A thermostatic faucet is a device that regulates the outlet temperature of the mixed water. The thermostatic faucet generally includes a shell, a valve body, a thermostatic valve core and a thermostatic handwheel. The hand wheel is installed on the thermostat valve stem hand. When in use, the thermostatic valve core can automatically adjust the mixing ratio of cold and hot water to ensure that the outlet water temperature is maintained at the set temperature. [0003] The thermostatic valve core has high requirements on the cleanliness of the water flow. In order to avoid the fine particles in the water from causing the piston inside the thermostatic valve core to be stuck, a filter is installed on the water inlet 2 and the water inlet 1 of the thermostatic valve core. Fine...
