Description

Technical Field

[0001] The utility model belongs to the technical field of thermostat structures, in particular to a structure for regulating the lift of a thermostat. Background Art

[0002] Vehicle manufacturers need to conduct engine bench durability tests or vehicle thermal balance tests and understand the flow rate under different thermostat lifts. They need to conduct a fully open thermostat test, but the existing thermostat wax can only change the lift at different engine temperature points. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing thermostat temperature-sensitive wax can only change the lift at different temperature points of the engine. If the thermostat needs to confirm the flow at a certain lift (such as 3.5mm lift), the temperature-sensitive wax must sense the temperature to obtain the lift.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model provides a thermostat structure with adjustable lift, including a valve seat, a screw arranged on the valve seat, and an induction body arranged at the end of the screw away from the valve seat, the end of the screw close to the induction body is provided with a thread and is connected to a lower nut, and the lower nut can be rotated to push the induction body to move downward.

[0005] Preferably, the screw is a full-thread screw.

[0006] Preferably, when the lower nut is rotated to push the inductor, the inductor moves along the direction of the screw rod.

[0007] Preferably, the valve seat is fixedly connected with an upper nut, and the screw rod is connected to the valve seat via the upper nut.

[0008] Preferably, the length of the thread on the screw between the valve seat and the induction body is 0 to 8 mm.

[0009] Preferably, the induction body is passed through the end of the screw rod away from the valve seat, and the lower nut abuts against the induction body.

[0010] In summary, the utility model includes the following beneficial technical effects:

[0011] The utility model has a simple appearance and structure. The thermostat is opened by a screw and a nut, and the height of the lower nut is adjusted to achieve different lifts of the thermostat, thereby testing the flow rates of different lifts. When the whole vehicle is subjected to a thermal balance test, a fully open thermostat test is required, which can also be achieved by using a screw and a nut to open the thermostat. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1The utility model is a structural schematic diagram of adjusting the thermostat lift through a screw rod and a nut.

[0013] Figure numerals: 1. full-thread screw; 2. valve seat; 3. induction body; 4. upper nut; 5. lower nut. DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The utility model discloses a thermostat structure with adjustable lift, which comprises a valve seat 2, a sensor 3, an upper nut 4, a lower nut 5 and a full-thread screw 1 connecting the above.

[0016] The bottom of the valve seat 2 is connected to one end of the full-thread screw 1, and the valve seat 2 and the full-thread screw 1 are firmly fixed by the upper nut 4. The induction body 3 is connected to the other end of the full-thread screw 1, and the lower nut 5 is in contact with the induction body 3. The lower nut 5 rotates on the full-thread screw 1 to push the induction body 3 downward, thereby pushing the valve to open.

[0017] The screw between the valve seat 2 and the induction body 3 has sufficient thread length to ensure that the thermostat lift is 0-8mm; the valve seat 2 and the induction body 3 can use the structure of the normal thermostat, and the screw and nut can use the standard full-thread screw 1 and nut; the valve seat 2 and the induction body 3 are connected by the full-thread screw 1. The full-open lift of the thermostat can be adjusted by adjusting the length of the screw engagement between the lower nut 5 and the full-thread screw 1.

[0018] The utility model has a simple appearance and structure, and can realize stepless adjustment of the thermostat lift. The utility model replaces the push rod of the valve seat 2 and the induction body 3 in the normal thermostat structure with a screw rod to realize different lifts of the thermostat, and then test the flow corresponding to different lifts. Compared with the traditional fully open thermostat, the utility model does not need the temperature-sensitive wax in the induction body 3 to be subjected to high temperature to ensure the thermostat is opened, and the factory does not need to customize the fully open push rod, which greatly reduces the production cost.

[0019] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
