Abstract
The invention belongs to the automobile accessory field, and discloses an automobile engine thermostat. The automobile engine thermostat comprises a large circulation water outlet pipe, a small circulation water outlet pipe, a large blanking cap and a small blanking cap, wherein the large blanking cap is a housing in multilayer step structure, the large blanking cap is connected with the small blanking cap through a telescopic cylinder, a buffer spring is arranged at the bottom of the small blanking cap, the diameter of a step at the bottom of the large blanking cap is larger that the diameter of the large circulation water outlet pipe, the large circulation water outlet pipe is matched with the structure of the large blanking cap, the buffer spring is made of memory metal material, and the diameter of the small blanking cap is larger than the diameter of the small circulation water outlet pipe. The automobile engine thermostat has the advantages of being obvious in heat dissipation and strong in corrosion resistance, and facilitating dust prevention.
Description
Technical field
The invention belongs to auto parts machinery field, be specifically related to a kind of motor car engine and save warm device.
Background technique
Along with the needs of the modern life, automobile is more and more, motor car engine is when cold start-up, thermostat is automatically to regulate according to the height of cooling water temperature the water yield that enters radiator, change the range of DO of water, to regulate the heat dissipation potential of cooling system, assurance motor is worked in suitable temperature range.For existing thermostat of automobile engine, when motor has just started and water temperature rises to certain degree, short circle blanking cover is opened and is moved downward, now major cycle blanking cover starts to fall, major cycle is opened, and such advantage is simple in structure, easily discharges the bubble in cooling system; Shortcoming is that thermostat often opens and closes when work, produces oscillatory occurences.In addition, low-temperature cooling water enters major cycle too early, add the reason of large and small cycles lid poor sealing, motor heat energy is scattered and disappeared from radiator in advance, and then slow down the engine water temperature rate of climb, motor is in lower water temperature work, and the poor oil consumption of discharge is high, has a strong impact on the normal work of motor.
Summary of the invention
The present invention is intended to overcome the defect of prior art, provides a kind of motor car engine to save warm device, have joint temperature obviously, the feature of good airproof performance.
Technological scheme of the present invention is as follows: a kind of motor car engine saves warm device, comprise major cycle outlet pipe 1, short circle outlet pipe 2, large blanking cover 3 and little blanking cover 4, described large blanking cover 3 is multilayer steps shape housing, between described large blanking cover 3 and little blanking cover 4, by retracting cylinder 5, be connected, described little blanking cover 4 bottoms are provided with damping spring 6, and large blanking cover 3 bottom stage diameters are greater than major cycle outlet pipe 1.
Described major cycle water outlet pipe end matches with large blocking cover structure.
Described damping spring is memory metal material
Described little blanking cover diameter is greater than short circle diameter of outflow tube.
Compared with prior art, the present invention has following beneficial effect:
The present invention is simple in structure, adopts mostly head and the major cycle outlet pipe port that matches of structure of many stepped shapes housing, makes sealing enhancing, saves warm efficiency high, and cooling liquid warming velocity is fast; Little blanking cover bottom is provided with damping spring and is difficult for producing vibration, long service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that motor car engine of the present invention saves warm device.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of motor car engine saves warm device, comprise major cycle outlet pipe 1, short circle outlet pipe 2, large blanking cover 3 and little blanking cover 4, described large blanking cover 3 is multilayer steps shape housing, between described large blanking cover 3 and little blanking cover 4, by retracting cylinder 5, be connected, described little blanking cover 4 diameters are greater than short circle diameter of outflow tube.Described little blanking cover 4 bottoms are provided with damping spring 6, and described damping spring is memory metal material.Large blanking cover 3 bottom stage diameters are greater than major cycle outlet pipe 1, and described major cycle outlet pipe 1 end matches with large blanking cover 3 structures.
The present invention is simple in structure, adopts mostly head and the major cycle outlet pipe port that matches of structure of many stepped shapes housing, makes sealing enhancing, saves warm efficiency high, and cooling liquid warming velocity is fast; Little blanking cover bottom is provided with damping spring and is difficult for producing vibration, long service life.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any modification of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
Claims (4)
1. a motor car engine saves warm device, comprise major cycle outlet pipe, short circle outlet pipe, large blanking cover and little blanking cover, it is characterized in that: described large blanking cover is multilayer steps shape housing, between described large blanking cover and little blanking cover, by retracting cylinder, be connected, described little blanking cover bottom is provided with damping spring, and described large blanking cover bottom stage diameter is greater than major cycle outlet pipe.
2. motor car engine saves warm device according to claim 1, it is characterized in that, described major cycle water outlet pipe end matches with large blocking cover structure.
