Abstract

The invention relates to a temperature controlling valve. A thermodynamic element sensitive to the temperature is arranged at a hot water outlet end for sensing the temperature of hot water; a control valve is arranged in a water inlet pipeline of a heating device; and the state of the thermodynamic element controls the state of the valve to realize the control on the temperature of the hot water. During heating the water by a heater, when the thermodynamic element senses that the temperature of the hot water reaches the designed outlet temperature, the thermodynamic element actuates to open a water inlet valve of the heater to make the hot water reach the designed temperature flow out of the heater; and when the heater stops heating, or the temperature of the hot water is lower than the designed temperature, the thermodynamic element actuates to close the water inlet valve of the heater to stop the hot water from flowing out. The state of the water inlet valve is controlled by the temperature of the hot water to realize the control on the temperature of the hot water. The temperature controlling valve has simple structure, low cost, high reliability and high control precision, and is suitable for various heating modes and the control of various temperatures of the hot water.

Description

Technical field:

[0001] The invention is a temperature control valve, which belongs to the field of valves. Background technique:

[0002] In the existing temperature control valve, there are many technical solutions, one is the electronic control method: the temperature of the hot water is detected by the electronic temperature sensor, and the liquid flow and heating electric power are controlled by the control circuit board to achieve the purpose of controlling the temperature of the hot water outlet , It is characterized by high control precision, complex control circuit and control program, high control cost and high failure rate. The second is to use various temperature sensitive devices to form a mechanical temperature control valve: use thermal elements composed of temperature sensitive materials such as bimetallic materials, shape memory alloy materials, thermal wax materials, temperature sensitive gases, and temperature sensitive liquids to control the state of the ...

Embodiment Construction

[0012] combined with figure 1 And attached figure 2 Be specific.

[0013] In the figure, 1 is the thermal element temperature sensing body, 2 is the hot water outlet, 3 is the sealing ring, 4 is the power rod of the thermal element, 5 is the valve seat, 6 is the cold water inlet, 7 is the compression spring, and 8 is the valve. Core, 9, valve core gasket, 10, valve seat gasket, 11, cold water outlet, 12, hot water inlet, 13, valve body, 14, heating device, 15, connecting water pipe.

[0014] When the heating device 14 is heated, the temperature of the water in the heating device is heated, and the thermal element temperature sensing body 1 feels that when the temperature of the hot water rises to the temperature of the opening valve set by the temperature control valve, the thermal element power rod 4 The action pushes the valve core 8 and the valve core gasket 9 away from the valve seat 5, and the valve is opened. At this time, cold water enters the valve body 13 from the ...
