Description

Technical Field

[0001] The present application relates to the technical field of thermostats, and in particular to a thermostat. Background Art

[0002] The cover thermostat has two closed chambers, one of which is open, so that the coolant flows back to the inlet of the water pump through the bypass valve of the thermostat, forming a small cycle; the other closed chamber is connected to the radiator through a guide rail, so when the water temperature inside the engine rises, the water outlet valve of the radiator is opened, so that the coolant flows through the engine radiator for a large cycle, but because two closed chambers are used, when the large cycle is in progress, the coolant cannot be stopped immediately for a small cycle, and some coolant is still in progress for a short time; therefore, the amount of coolant passing through the water outlet valve of the radiator is relatively small, which reduces the efficiency of lowering the water temperature inside the engine body, resulting in a prolonged cooling time.

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a thermostat, including:

[0005] Cover body;

[0006] A liquid inlet is provided on one end of the cover body;

[0007] The first circulation chamber is provided on one end of the cover body and is communicated with the liquid inlet;

The coolant realizes a small circulation in the engine, so that the coolant temperature in the engine can rise rapidly, which can quickly and effectively improve the operating temperature of the engine; when the coolant temperature reaches the specified value, the valve body assembly of the thermostat opens, and the coolant flows back to the engine through the water pump under the action of the radiator and thermostat, forming a large circulation to reduce the temperature in the engine.

[0013] Furthermore, the valve body assembly also includes a temperature sensor electrically connected to the pneumatic actuator, and a controller for driving the pneumatic actuator and the temperature sensor.

[0014] Furthermore, one end of the first liquid outlet is configured as a first flared portion.

[0031] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0032] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0033] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] Reference Figure 1-2 The thermostat comprises a housing 1, a liquid inlet 2, a first circulation cavity 3, a second circulation cavity 4, and a valve body assembly; the housing 1 is provided with a liquid inlet 2, a first circulation cavity 3, and a second circulation cavity 4; the first circulation cavity 3 is connected to the liquid inlet 2, and the second circulation cavity 4 is connected to the first circulation cavity 3 to form a through cavity 5; the valve body assembly is arranged in the through cavity 5. The housing 1 is provided with a plurality of connection holes 6 for connecting with the engine.

[0036] The cover body 1 is further provided with a first liquid outlet 7 and a second liquid outlet 8 ; the first liquid outlet 7 includes a first cavity 9 communicating with the first circulation cavity 3 ; the second liquid outlet 8 includes a second cavity 10 communicating with the second circulation cavity 4 .

[0037] The first liquid outlet channel and the second liquid outlet channel are arranged in parallel.

[0038] The liquid inlet 2 and the first liquid outlet channel are arranged vertically.

[0039] One end of the first liquid outlet 7 is configured as a first flared portion 11 ; one end of the second liquid outlet 8 is configured as a second flared portion 12 ; and one end of the liquid inlet 2 is configured as a third flared portion 13 .

[0040] The valve body assembly includes a blocking member 14, a pneumatic actuator 15, a temperature sensor 16, and a controller; the pneumatic actuator 15 is arranged on the inner wall of the through cavity 5, one end of the blocking member 14 is connected to the pneumatic actuator 15, the temperature sensor 16 is arranged on the through cavity 5, the controller is arranged on the cover body, and the controller is thermoelectrically connected to the temperature sensor 16 and the pneumatic actuator 15; wherein, the temperature sensor 16, the pneumatic actuator 15, and the controller are all existing technologies on the market, and the structure is not repeated; when the temperature sensor 16 senses that the temperature in the thermostat becomes high, the signal is fed back to the pneumatic actuator 15, and the pneumatic actuator 15 can push the blocking member 14 to move, block one end of the first cavity 9, and disconnect the connection between the first cavity 9 and the first circulation cavity 3. When the temperature of the coolant in the engine is low, the thermostat will feed back a signal to the pneumatic actuator 15 through the temperature sensor 16, and the pneumatic actuator 15 can push the blocking member 14 to move, close the first circulation chamber 3, and allow the coolant to flow directly into the engine body or cylinder head water jacket through the inlet of the second circulation chamber 4. The coolant realizes a small circulation in the engine, so that the coolant temperature in the engine can rise rapidly, and the operating temperature of the engine can be quickly and effectively improved; when the temperature of the coolant reaches the specified value, the valve body assembly of the thermostat opens, and the coolant flows back to the engine through the water pump under the action of the radiator and the thermostat, forming a large circulation to reduce the temperature in the engine.

[0041] When the thermostat is produced, some of the self-tapping screw holes or bolt holes on the thermostat are no longer fine-machined and are directly used for assembly. The circumferential surface is not allowed to have appearance defects such as bruises, flash burrs, etc. Therefore, the burrs must be removed manually or by punching with a partial trimming die. Manual removal often causes many quality problems such as damage and omissions of the product, which requires rework or scrapping. Punching sometimes causes the burrs of the skin to flanging, or the punch needle sticks to aluminum, causing damage to the inner hole. Therefore, the present application also discloses a production and processing method for the thermostat;

[0042] This application eliminates the trimming and burring process and replaces it with a machining process, so there are no quality problems such as missed processing and cutting damage. The burrs of the relevant holes are removed with a ball cutter, which greatly improves the original operation of manually removing the burrs on the parts with a file after machining. Thermostat diameter hole diameter The process tool composed of a rough milling cutter + an integrated fine milling cutter for the original center hole has been changed to a rough milling cutter + a replaceable blade boring cutter, which greatly reduces the cost of using the tool and reduces the scrapping of products due to rigidity issues. As a result, this application has been cleverly designed through summarizing the actual operation problems, process quality complaints, and production efficiency in the early stage. Through the design of tooling to avoid air during machining, the selection of tools, and the increase of work step instructions, the product can be stably fixed on the tooling. Through the force of the hydraulic press, all the casting holes on the product can be simultaneously removed from the burrs at one time. The machined hole and the blank feature are intersected by a machined tool to remove the flanging. The inner hole diameter is stable while achieving high efficiency and stable quality, thereby avoiding the occurrence of artificial traces of missing skins and burrs. This can effectively improve production efficiency and reduce production costs.
