Temperature control valve and temperature control device

Abstract

The invention belongs to the technical field of automobile gearbox engine oil temperature control, and relates to a temperature control valve and a temperature control device. The temperature controlvalve comprises a valve body, a temperature control unit and a valve body, wherein the valve body is provided with a first valve port, a second valve port, a third valve port, a fourth valve port anda fifth valve port; the temperature control unit is connected to the inner wall of the valve body in a sealing manner and is used for dividing a valve cavity into a water cavity and an oil cavity which are isolated from each other; the first valve port, the second valve port and the third valve port are communicated with the water cavity; the fourth valve port and the fifth valve port are communicated with the oil cavity; when the temperature control unit senses that the temperature of the liquid in the oil cavity is lower than a preset temperature, the valve is controlled to be kept at or move to a first position; and when the temperature control unit senses that the temperature of the liquid in the oil cavity is higher than or equal to the preset temperature, the valve is controlled to be kept at or move to a second position. The temperature control valve can accurately control the temperature of the liquid in the oil cavity and can keep stable switching pressure of a cooling systemloop.

Description

technical field [0001] The invention belongs to the technical field of oil temperature control of automobile gearbox, and in particular relates to a temperature control valve and a temperature control device. Background technique [0002] In order to better adjust the temperature of the gearbox oil, it is necessary to arrange temperature control valves on the oil circuit and water circuit of the gearbox. The settings for the temperature control valve in the prior art usually include the following: [0003] (1) Wax-type temperature control valve integrated in the cooling water circuit: when the temperature control valve is running, the engine oil temperature is high and the water temperature is low. At this time, the temperature control valve cannot be opened in time to cool the engine oil, so the temperature control valve Programs are generally not used. [0004] (2) The cooling system integrates an electric three-way valve: When the temperature control valve is switched, ...
