Abstract
The utility model relates to a temperature saving device of an inner combustion machine, which adopts the cooperation of a valve plate and the main port and the side port on a valve shell to realize temperature saving regulation. The valve plate is controlled by a control component to realize the switching of the main passing water path and the side passing water path. The control component comprises an intelligent spring and a reset spring. The intelligent spring is made from the material of shape memory alloy. Thus, the valve plate is driven to rotate to close and open the main passing water path and the side passing water path. The device has simple structure, simplified manufacture process, sensitive action, accurate opening and closing temperature, high reliability and strong adaptability. Compared with the prior temperature saving device, the cost is reduced by 30%.
Description
The utility model relates to a kind of internal-combustion engine special accessories, the warm device of specifically a kind of joint.
The thermostat that uses on the existing internal-combustion engine is to realize the adjusting of joint temperature by valve block and main port and cooperating of by-pass port on the valve casing, valve block is controlled by control unit, realize that the master is led to and the switching of bypass water channel, control unit is generally made as temperature-sensitive material by paraffin or ether, along with temperature variation, by the volumetric expansion of inductive material or shrink and control valve block and move up and down, switch main port and by-pass port, thereby open or turn-off main, bypass water channel, realize the joint temperature control.The complex structure of this control unit, the manufacturing process complexity, and very strict to the purity and the sealing requirements of inductive material.Be easy to generate in the use and shorten the phenomenon that rate of fault and cost improve the working life that the leakage because of inductive material causes.
The purpose of this utility model just provides a kind of cost thermostat new structure low, simple in structure, to improve working life.
The utility model is achieved in that on the basis of existing thermostat structure, control unit is made for the mechanism that is made of intelligent spring and return spring.So-called intelligent spring, i.e. the spring of being made by shape memory alloy material relies on the characteristic of its shape physical alterations (being length change) under different temperatures, the rotation angle of control valve block, thus reach switching main, the bypass water channel.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1.
As shown in Figure 1, 2, this device keeps the profile of existing thermostat valve casing constant, to adapt to the structure of existing internal-combustion engine.Valve block 2 is made for cruciate flower shape, and the center has axle 3 to be fixed on the support 4 of valve casing 1 top center and valve casing bottom, and support 4 can adopt welding fixing with valve casing 1.The control unit of being made up of intelligent spring 5 and return spring 6 all is enclosed within on the valve block central shaft 3, the two ends of two springs are separately fixed on the support 4 of locating stud 7 on the central shaft 3 and valve casing bottom, valve casing 1 top master's port 8 is four fan shaped boreholes of symmetry, its central angle is in 40 °, and the by-pass port 9 of valve casing side is four rectangular openings.So original bypass two holes, main logical single hole are changed into bypass and mainly logically be four hole structures, water-flowing amount is increased, the joint temp effect improves.The open-angle of each page of cruciate flower shape valve block sheet is about 45 °, can cover the fan-shaped main port on the valve casing fully.The front curvature of each page of valve block sheet constitutes the crooked identical shape with valve casing end face and sidewall, thereby makes the front curvature portion of every page of valve block can shelter from rectangle by-pass port on the valve casing.The rotation of valve block realizes by the intelligent spring and the return spring that are fixed on support and the valve block central shaft, promptly provides starting torque by intelligent spring, and making before the valve block changes, and provides the initial torque of recovery by return spring, makes the valve block revolution.Open or turn-off main, bypass water channel by the mode of rotation like this.
The utility model makes it simple in structure owing to adopt the intelligent spring of being made by shape memory alloy material as control element, and manufacture craft is simplified, and the existing thermostat of cost reduces by 30%. And be active in one's movements, it is accurate to open and close temperature. This device all can use reliability height, long service life on existing internal combustion engine.
Claims (3)
1, the intelligent thermostat of a kind of internal-combustion engine, by valve block and main port and cooperating of by-pass port on the valve casing realizing the adjusting of joint temperature, valve block is controlled by control unit, realizes that the master is led to and the switching of bypass water channel, it is characterized in that control unit is made of intelligent spring and return spring.
