Temperature regulating valve

A thermostatic valve, comprising:

• a valve body with a cavity;
• an end cover assembly;
• and
• a thermal actuator, a first spring and a second spring installed in the cavity;
• wherein
• the valve body is provided with at least three ports, the three ports comprise a first port, a second port and a third port;
• the thermal actuator comprises a valve rod and a main body;
• wherein the thermostatic valve comprises a first valve port and a second valve port;
• the thermostatic valve operates in at least two operation states:
• in a first state, the second valve port is open and the first port is in communication with the second port through the second valve port;
• and in a second state, the first valve port is open and the third port is in communication with the first port through the first valve port;
• the thermal actuator comprises a first valve core and a second valve core;
• the main body is away from the end cover assembly relative to the valve rod, and the first valve core is away from the end cover assembly relative to the second valve core;
• the first valve core matches with the first valve port, and the second valve core matches with the second valve port;
• the second valve core is fixedly arranged on the main body or is a part of the main body, the first valve core is arranged in sliding fit with the main body;
• the first spring and the second spring are respectively located on two sides of the first valve core, the first spring is located on one side of the first valve core that is relatively away from the end cover assembly, the second spring is located on one side of the first valve core that is relatively close to the end cover assembly, one end of the second spring directly or indirectly abuts against the first valve core and the other end of the second spring directly or indirectly abuts against the main body of the thermal actuator;
• and
• the thermostatic valve comprises a guiding part fixedly arranged with respect to the thermostatic valve, and the thermal actuator comprises a guide fitting part fitting with the guiding part.

A thermostatic valve, comprising:

• a valve body with a cavity;
• an end cover assembly;
• a thermal actuator installed in the cavity;
• a spring;
• a fixedly arranged guiding part;
• and
• a matching cavity, wherein
• the valve body is provided with at least three ports, the three ports comprise a first port, a second port and a third port;
• the thermal actuator comprises a valve rod and a main body, the cavity comprises a first cavity and a second cavity, and the second cavity is away from the end cover assembly relative to the first cavity;
• the first port is in communication with the first cavity, and the third port is in communication with the second cavity;
• the spring is partially or completely located in the second cavity;
• and the thermal actuator is at least partially located in the first cavity, and the first cavity is larger than the thermal actuator;
• one end of the thermal actuator directly or indirectly abuts against or is supported on one end of the spring close to the thermal actuator, and the other end of the thermal actuator is position-limited to the end cover assembly;
• the thermal actuator comprises a guide fitting part that is in sliding fit with the guiding part;
• and
• the main body of the thermal actuator comprises a fitting section, in a case that the fitting section is partially located in the matching cavity, the fitting section and the matching cavity are in sliding fit, and the fitting section is relatively away from the end cover assembly, and the fitting section is smaller than the matching cavity.
