Barrier-free used concealedly-installed control valve

Abstract

The invention relates to a barrier-free used concealedly-installed control valve. The control valve comprises a concealedly-installed box, a concealedly-installed body and a rotary-control type thermostatic valve. The thermostatic valve is installed in the concealedly-installed body and arranged between a water inlet channel and a water outlet channel of the concealedly-installed body. The concealedly-installed body is installed in the concealedly-installed box. A pressing type switch valve is arranged between the thermostatic valve and the water inlet channel. A rotary hand wheel is arranged at the end of the switch valve. Linkage is achieved between the rotary hand wheel and a thermoregulation assembly of the thermostatic valve. The rotary hand wheel is pressed once, the switch valve is closed, the thermostatic valve and the water inlet channel are blocked, and the rotary hand wheel is not higher than a panel of the concealedly-installed box. The rotary hand wheel is pressed again, the switch valve is opened, the thermostatic valve communicates with the water inlet channel, and the rotary hand wheel extends out of the panel of the concealedly-installed box. According to the barrier-free used concealedly-installed control valve, barrier-free operation can be conducted. The control valve has anti-scalding and anti-cold functions and a secondary starting anti-scalding function, and anti-scalding and anti-cold effects are both achieved through arrangement of exceeding prompting tap positions, namely, the possibility that water temperature is adjusted to be low due to the fact that the hand wheel is accidentally driven by clothes, a bath towel and the like to rotate is avoided completely.
