Delay-start constant-temperature control valve and working method thereof

Abstract

The invention relates to the field of temperature control valves, in particular to a delay-start constant-temperature control valve and a working method thereof. The constant-temperature control valvecomprises a mixed flow valve, a shell, a temperature sensing actuator, a reset mechanism, a locking mechanism, a water flow switch and a temperature control switch; a water inlet and a water outlet are formed in the shell, and the water inlet communicates with the output end of the mixed flow valve; the temperature sensing actuator is arranged in the shell, a non-working part of the temperature sensing actuator is capable of sliding in a certain stroke, and the temperature sensing actuator is used for sensing the water temperature in the shell and driving a valve core to move according to thewater temperature; the reset mechanism enables the temperature sensing actuator to always maintain the tendency of moving towards the starting point of own stroke; the locking mechanism is used for locking a transmission mechanism so that the transmission mechanism is unable to move; the water flow switch is used for sensing water flow in the shell and turning on or off the locking mechanism; andthe temperature control switch is used for sensing the water temperature in the shell and starting or closing the locking mechanism. The delay-start constant-temperature control valve is closed immediately after water is shut off and is started in a delayed way after water comes in, and the output water temperature can be automatically regulated.

Description

technical field [0001] The invention relates to the field of temperature control valves, in particular to a delayed start thermostatic temperature control valve and a working method thereof. Background technique [0002] Temperature control valve, as the name suggests, is a valve that controls the temperature of the fluid, which is divided into manual and automatic. The manual temperature control valve controls the ratio of cold and hot fluids by manually adjusting the valve core, and then controls the temperature of the outlet fluid, which has the disadvantage of inconvenient operation. The automatic temperature control valve uses the thermal expansion and contraction of the thermostat to push the valve stem to change the valve opening, change the flow ratio of cold and hot fluids, and make the temperature reach the set temperature. [0003] In the existing thermostatic valve, the temperature sensing module is generally installed at the water outlet, and the water temperat...

Problems solved by technology

[0006] As a result, when the user opens the water outlet again, hot hot water will be released first after the residual cold water in the water pipe is emptied, and the temperature control valve needs a period of time to balance the ratio of hot water to cold water. During this period of water temperature, it is easy to cause burns to the user
