Problems solved by technology

The handwheel of this patent is only suitable for civil plumbing, and the temperature range of adjustment is small, so it cannot be applied in industry; secondly, the handwheel of this patent can still move after the temperature is set, and it will move under the action of the ring spring. Return to the original position, cannot maintain the given state well, and cannot meet the safety requirements for industrial use

Embodiment 2

[0030] The content of embodiment 2 is basically the same as that of embodiment 1, the difference is that the clutch structure includes a clutch member and an outer gear ring 5 arranged on the outer ring of the indicator ring 2, and the clutch member includes a connecting rod passing through the above-mentioned scale ring 3 The connecting rod and the ring-shaped inner gear ring connected with the connecting rod, the inner gear ring is located on the outside of the outer gear ring 5, and the inner ring of the inner gear ring is provided with a tooth shape matching the above-mentioned outer gear ring 5, when When the main body 1 slides to the indicator ring 2, the inner toothed ring meshes with the outer toothed ring 5. When the body 1 slides to the indicator ring 2, the inner gear ring of the clutch slides to the outside of the outer gear ring 5 and contacts the outer gear ring 5, and the inner gear ring meshes with the outer gear ring 5, because the outer gear ring 5 is fixed ,...

Abstract

The invention provides a handwheel of a constant temperature mixing valve, belonging to the technical field of valve. The handwheel resolves the technical problems of the existing constant temperature handwheel that the temperature adjusting range is small and the existing constant temperature handwheel can not be applied in industry, etc. The constant temperature mixing valve comprises a body, an indicating ring and a scale ring positioned between the body and the indicating ring; the body, the indicating ring and the scale ring are arranged on a coaxial line; the body and the scale ring are circumferentially fixed; the body is equipped with a clutch part which is arranged in and connected with the scale ring by sliding; and a clutch structure and a positioning structure are arranged between the body and the indicating ring. The handwheel of the constant temperature mixing valve has precise and firm positioning; the operation of clutch and temperature adjusting can be realized by pulling up the body, rotating the body to a preset temperature and pressing the body down; the use is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a thermostatic mixing valve, in particular to a handwheel of the thermostatic mixing valve. Background technique [0002] The handwheel device of the thermostatic mixing valve drives the internal temperature-limiting rod to rotate along the track planned by the temperature-limiting partition by controlling the button on the handwheel, so as to adjust and limit the outlet water temperature after mixing cold and hot water. [0003] Existing thermostatic mixing valve handwheels such as the "a kind of constant temperature handwheel" disclosed by the Chinese patent authorization announcement number CN2908953Y mainly include a handwheel part, a temperature adjustment disk and a temperature gear display disk, and the handwheel is nested in the temperature On the adjustment plate, screw the countersunk head screw on the screw hole of the fastening temperature adjustment plate and the handwh...
