Description

technical field [0001] The invention relates to a temperature self-regulating three-channel ball valve based on a temperature-sensing spring, especially its flow-reducing buffer structure. Background technique [0002] Usually, in the prior art, the temperature-sensing spring is usually used near the side of the hot water pipe or near the side of the cold water pipe, or the temperature-sensing spring is arranged in the mixing chamber of cold water and hot water, so that the temperature felt by the temperature-sensing spring does not vary. It cannot accurately reflect the actual mixing temperature or the temperature of the water in the output pipeline. [0003] Invention Patent Publication No. CN111043355A discloses a three-channel ball valve structure with automatic temperature control. This structure proposes to set a shunt channel on one side of the output channel, and the valve body is provided with a circulation circuit that communicates with the mixing chamber through a...

Problems solved by technology

Moreover, the reliability of driving the sheave through the steel wire rope and then driving the rotation of the two-way valve stem is poor. Since the water flow generated by the hot and cold water pipes will have a greater impact on the two-way valve stem, only the elastic deformation generated by the temperature sensing device, Can not control the rotation of the two-way valve stem very well

[0005] And the water flow of the circulation structure will inevitably affect the rotation control of the two-way valve stem and the deformation of the temperature sensing device.

[0006] In addition, the deformation generated by the temperature sensing device and the driving force provided by the return spring are relatively small, which cannot well adapt to the torque required by the two-way valve stem, and will eventually cause temperature control failure

[0007] And the deformation of the temperature sensing device is equal to the circular rotation arc length of the rotating wheel, and the corresponding rotation angle is small, which cannot effectively and accurately rotate the two-way valve stem, resulting in defects in water temperature regulation
