Detailed Description
The invention provides a motor temperature regulator with an error prevention function and an engine system.
In order to make the technical solution provided by the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-3, the motor thermostat with error protection provided by the present embodiment includes a housing 2 and an actuator Z, wherein the housing 2 includes a small circulation channel 21, a heat dissipation channel 22, a small circulation valve 101 connected in series with the small circulation channel 21, a heat dissipation valve 102 connected in series with the heat dissipation channel 22, an error protection parallel pipeline 23 connected in parallel with the heat dissipation channel 22, and a pipeline valve 103 connected in series with the error protection parallel pipeline 23.
The pipeline valve 103 is opened when the actuator Z is damaged and the protection temperature of the engine F reaches a preset value, is closed when the actuator Z is normal in use and the protection temperature of the engine F is lower than the preset value, and is connected with an error-proof parallel pipeline in parallel and is provided with the pipeline valve 103, so that large circulation can still be opened under the condition that the actuator of the motor thermostat is damaged, the problem that the temperature of the engine is overhigh due to the damage of the thermostat is solved, the error-proof function is realized, and the reliability of the operation of the engine is ensured.
The preset value is a temperature value of forward opening of the pipeline valve, and is not a fixed value, but can be specifically set according to specific requirements of the highest protection temperature of the engines of different types and models.
Preferably, the pipeline valve 103 comprises a valve 35 and a memory metal 34 which is arranged on the valve 35 and has a deformation temperature of a preset value. The memory metal 34 is in a bent state when the temperature is lower than a preset value, and the valve 35 is in a closed state; when the temperature of the memory metal 34 is greater than or equal to a preset value, the memory metal is changed from a bent state to a straightened state, so that the valve 35 can be pushed open, and the valve 35 is in an open state. The memory metal 34 is an alloy having a "memory" shape function, which is a very special metal strip that is very flexible, is formed into a long strip shape in a high temperature environment, and is formed into a curved shape when it is at a lower temperature, but is gradually straightened into a long strip shape if it is reheated. Specifically, nickel-titanium alloy material can be used as memory metal. The memory metal material is selected to have an engine protection temperature value, and is deformed when the maximum engine protection temperature is 110 ℃.
Specifically, one end of the memory metal 34 is disposed on the valve 35, and the other end is disposed on the inner wall of the error-proof parallel pipeline 23. When the heat dissipation valve 102 cannot be opened due to the failure of the actuator Z, the memory metal senses the ambient temperature to deform when the engine F is continuously heated to a preset value, and the memory metal 34 changes from a bent state to a straightened state when the temperature is greater than or equal to the preset value, so that the valve 35 is pushed open, and the valve 35 is in an open state.
Preferably, the pipeline valve 103 further comprises a valve cover 31, a valve rod 32 and a return spring 33 sleeved on the valve rod 32, wherein the valve cover 31 is provided with a chute for accommodating the valve rod 32, one end of the valve rod 32 is arranged in the chute, and the other end of the valve rod 32 is arranged on the valve 35.
When the temperature of the memory metal is lower than the preset temperature, the memory metal is in a bending state, the valve rod is pushed by the reset spring, and the valve port is in a closing state; when the temperature of the memory metal is greater than or equal to the preset value, the memory metal is changed from a bending state to a straightening state, the valve rod is pushed by the memory metal and overcomes the spring force of the reset spring, and the valve rod can relatively slide and shrink to be arranged in the chute of the valve cover, and the valve port is in an open state, so that the engine high-temperature water flows into the radiator to be cooled as soon as possible, and the engine temperature is rapidly reduced to a reasonable working temperature.
In the connection relation in the system, as shown in fig. 1, one end of the heat dissipation channel 22, one end of the error-proof parallel pipeline 23 and one end of the small circulation channel 21 are all communicated with the engine inlet channel; the other end of the small circulation passage 21 is respectively communicated with an engine outlet passage and a radiator outlet passage; the other end of the heat dissipation channel 22 and the other end of the error-proof parallel pipeline 23 are both communicated with the radiator inlet channel.
The casing 2 further includes a transmission shaft 201 and a valve ball 202, one end of the transmission shaft 201 is connected to the actuator Z, the other end is connected to the valve ball 202, and the valve ball 202 is used for communicating the small circulation passage 21 and the engine inlet passage when rotating to the first position, and communicating the heat dissipation passage 22 and the engine inlet passage when rotating to the second position.
The motor attemperator 1 is a mechanical attemperator or an electronic attemperator.
The scheme provides an engine system, including engine F and cooling system, cooling system includes above-mentioned motor attemperator 1 and radiator S.
Since the above-mentioned motor attemperator has the above technical effects, an engine system to which the motor attemperator is applied should also have the same technical effects, and will not be described in detail herein.
The scheme also comprises an actuator fault alarm device for monitoring whether the actuator Z fails. The fault of the actuator reports a fault code to a driver, and the driver is reminded to find a maintenance station as soon as possible to maintain the actuator. The motor temperature regulator with the structure can take temporary protection measures when vulnerable parts are in failure, and ensure the reliability and the driving safety of the engine.
The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
