[0003] Generally, the hot coolant of the engine is used to heat the transmission lubricating oil, but in a low-temperature environment, when the car is just started, the temperature of the engine coolant is relatively low. At this time, the coolant enters the heat exchanger and will take away A large amount of heat in the transmission lubricating oil, causing the temperature of the transmission lubricating oil to rise too slowly

The invention provides a fluid control valve. The fluid control valve comprises valve bodies, a thermodynamic element and a spring. A chamber is formed in one valve body. At least part of the thermodynamic element is located in the chamber. The fluid control valve further comprises a first channel, a second channel and a valve port part. The valve port part is provided with a valve port. The firstchannel communicates with the chamber. The first channel can communicate with the second channel through the valve port. The thermodynamic element comprises a body and a valve rod. The body abuts against the spring. The valve rod abuts against the valve body. The fluid control valve is further provided with a channel parallel to the valve port. One end of the channel communicates with the chamber. The other end of the channel communicates with the second channel. The throughput flow of the channel is less than that of the valve port. When the body abuts against the valve port, the body intercepts the valve port, and the second channel communicates with the first channel through the channel and the chamber. The fluid control valve provided by the invention is arranged in an automobile gearbox lubricating oil cooling system and can enable the temperature of lubricating oil in a gearbox to rise quickly.
Description
technical field [0001] The invention relates to the technical field of fluid control, in particular to a fluid control valve. Background technique [0002] The lubricating oil of automobile gearbox mainly realizes the temperature regulation function through the temperature control flow path composed of the temperature regulating valve and the heat exchange device for external cooling. When the car is just started, especially when starting in a low temperature environment, it is necessary to heat the gearbox lubricating oil to keep the gearbox lubricating oil at a suitable working temperature. [0003] Generally, the hot coolant of the engine is used to heat the transmission lubricating oil, but in a low-temperature environment, when the car is just started, the temperature of the engine coolant is relatively low, and the coolant enters the heat exchanger at this time and will take it away A large amount of heat in the gearbox lubricating oil causes the temperature of the ge...
