Description
Technical field
The utility model relates to the explosive motor accessory, is a kind of explosive motor water cooling control motor thermoregulator body more specifically.
Background technique
At present, the used thermoregulator of explosive motor also is thermostat.Known common thermoregulator is to be formed by inductor component (comprising body cap, body, push rod, sebific duct, expanding material), valve seat, valve, spring and holder combination.It is installed in the water outlet or the water inlet of cooling system, can regulate the flow direction and the flow of cooling water automatically according to the water temperature of mounting point.When engine cold-start, water temperature is low, and the thermoregulator valve is in closed condition, and cooling water all passes through short circle, and motor is rapidly heated.At the beginning of reaching, the water temperature of thermoregulator mounting point opens more than the temperature, the thermoregulator valve opening, make a part of cooling water carry out major cycle through radiator, after size circulated in the water inlet mixing, water temperature reduced, enter engine water jacket, engine water temperature is reduced, and the thermoregulator valve lift reduces thereupon, by this dynamic adjustments, the water temperature of motor is controlled within the scope of setting, prevents that motor from crossing cold or overheated.
Body, it is a kind of cup-shaped receptacle of brass material, it is connecting its inner body cap, push rod, sebific duct, expanding material and outside valve, valve seat, spring, support, and it is the fundamental parts of inductor, is basic, the most most crucial part of forming thermoregulator.Body plays the important function that under accurate control volume, flash heat transfer, the high-voltage pulse inductor is sealed, so its performance will directly have influence on reliability, sensitivity, the stability of thermoregulator.
Common thermoregulator main body structure shape as shown in Figure 1.Its adopts H90 copper coin material, through the stamping die stamping-out and draw and form, and its product wall thickness 〉=1.5mm, and seal area is the plane.There is following deficiency in this body product: (1) because this product adopts machine-tooled method and process for stamping manufacturing usually, and its waste of material is bigger, and manufacturing efficiency is low, and the manufacturing cycle is long, manufacture cost is bigger; (2) fatigue resistance is low can only reach 30,000 times, causes the thermoregulator life-span shorter; (3) seal area of body is the plane, and sealability is relatively poor, causes the leakage of thermoregulator easily; (4) cylindrical of body is straight wall, and the release force deficiency of thermoregulator assembling back body and valve causes valve to come off easily.For example, the thermoregulator valve body in patent " manufacture method of water cooling temp. regulator valve for internal combustion engine " publication number CN 101000008A uses copper coin to draw through punching press and forms, and its product seal area is the plane, and cylindrical is straight wall.
The model utility content
The purpose of this utility model is to solve the deficiency that the body product exists in the above-mentioned background technology, proposes a kind of good seal performance, easy to assembly, motor thermoregulator body with higher intensity and working life.
For achieving the above object, the utility model adopts following technological scheme: a kind of motor thermoregulator body, two cup shells that stepped circular cylinder body constitutes that this body is made by brass material, it is characterized in that: the transitional surface between described big or small two circular cylinder bodies is the conical surface that matches with the sebific duct sealing surface, described small circular barrel outer surface is a step surface, its valve mating face near transitional surface is higher than other surface of small circular cylindrical shell, this body is to utilize drawing and through the brass wire of annealing in process, use the cold-extrusion technology manufacturing to form.
In such scheme, described body wall thickness is not more than 1.5mm, preferred 1.1 ± 0.15mm.
In such scheme, the height of described step surface is not more than 0.5mm, preferred 0.2mm.
In such scheme, the bus of described conical surface and axis angle are preferably in 40 °-50 °.
The beneficial effects of the utility model are:
1, this thermoregulator body adopts the manufacturing of multi-position cold-extrusion technology, has improved working efficiency greatly, has reduced waste of material, has reduced the input of the human and material resources and the energy, and the manufacture cost of body has been reduced by 50%.
2, adopt the multi-position cold-extrusion technology to make this thermoregulator body, after making fine and close copper wires through the moulding of multi-position cold-extrusion technology, the base metal grain refinement, organize more fine and close, and a large amount of metal volume has taken place when cold extrusion shaped to be shifted, material has continuous fibrous structure, have higher intensity, can pass through 80,000 subpulse pressure tests, make thermoregulator durable reliable.
3, this thermoregulator body adopts the conical surface sealing, under identical product external diameter, seal area area than plane sealing has increased by 220%, and this body cone can provide the reaction force of substantially horizontal and Vertical direction simultaneously when sebific duct is extruded, can play more firm seal action, effectively prevent the leakage of expanding material when high pressure, thereby avoid the instability and the early failue of thermoregulator.
When 4, thermoregulator assembles, it is rough and uneven in surface that this external surface appears in inductor capacity correction operation, after this valve is press-fitted in the operation, body and valve itself are exactly interference fit, cause when top is pressed into, be stretched in advance from the bottom of body distortion or crack of valve easily, make assembling place on valve and body top be press-fitted not tight.And thermoregulator body described in the utility model designs a step surface that exceeds at the valve mating face, and it is closely firm with cooperating of valve to guarantee, avoids the early failue of thermoregulator.
