  • Patent number: 12000317
    Abstract: A temperature regulating valve and a thermal management system provided with the temperature regulating valve are provided. The temperature regulating valve includes a filling state and a first working state, and a thermodynamic element is impelled to not abut against a first valve seat by means of providing a hot melt in an end cover of the temperature regulating valve. When a first valve port is in an open state, at said time the temperature regulating valve is installed in the thermal management system, and since the first valve port is in the open state, lubricating oil may then flow into a heat exchange device by means of a first interface channel, the first valve port, and a second interface channel during a process of filling the lubricating oil.

  • Patent number: 11280423
    Abstract: Provided is a thermostatic valve including a first valve body, a second valve body, a third valve body, a first thermal actuator, a second thermal actuator, a valve core, a first valve port, a second valve port and a third valve port. The first valve body includes a second cavity and a third cavity. The second thermal actuator is sealedly fixed in the first valve body to isolate the second cavity from the third cavity. At least a part of the valve core is located in the second cavity. The valve core is connected to, or is integrated with, or abuts against a second valve stem of the second thermal actuator. The second thermal actuator is configured to act in response to a change in temperature of a fluid in the third cavity. The valve core is configured to open the second valve port or the third valve port in response to an action of the second valve stem.

  • Patent number: 11131379
    Abstract: A thermostatic valve, including: a pressure relief ring capable of moving up and down and disposed in a valve body cavity. In normal conditions, the pressure relief ring is abutted against the outer edge of a first valve seat via a spring. An internal channel capable of being opened or closed via up and down movement of the pressure relief ring is further provided in the valve body cavity; when the pressure of a fluid in the thermostatic valve is excessive, the fluid can drive the pressure relief ring to compress the spring, such that the internal channel is in communication with a third interface to realize simultaneous communication with a first flow channel and a third flow channel.

  • Publication number: 20200300354
    Abstract: Disclosed is a thermostatic valve, including: a pressure relief ring capable of moving up and down and disposed in a valve body cavity. In normal conditions, the pressure relief ring is abutted against the outer edge of a first valve seat by means of a spring. An internal channel capable of being opened or closed by means of up and down movement of the pressure relief ring is further provided in the valve body cavity; when the pressure of a fluid in the thermostatic valve is excessive, the fluid can drive the pressure relief ring to compress the spring, such that the internal channel is in communication with a third interface to realize simultaneous communication with a first flow channel and a third flow channel, and thus damages caused by excessive pressure of the fluid in the temperature regulating valve can be prevented.
