In this way, being generated since the initial elasticity deformation power of second spring 4 is greater than the first spring 5 when the second valve port 141 is closed
Elastic deformation power, second spring 4 and the first spring 5 are all in compressive state, since h2 is less than or equal to h1, at this time due to setting
There is solid state wax 7, keep at a distance h2 between one end and first step portion 64 of valve rod 33, and thermostatic element 3 is whole to the second valve port 141
Side is mobile, and second spring 4 is further compressed, and the first core portion 31 leaves the first valve seat 21 at this time, and the first valve port 211 is in and beats
Open state, the second core portion 32 keep small distance or the second core portion 32 to connect with the second valve seat 14 with the second valve seat 14
Touching, 141 small guide vane of the second valve port is opened or the second valve port 141 is in close state, and the aperture of the second valve port 141 is less than
The aperture of first valve port 211.So by solid state wax 7 first valve port 211 is opened under this setup, while the
Two valve ports, 141 small guide vane is opened or the second valve port 141 is in close state, under the lubricating oil non high temperature for flowing into heat control valve
When, it is also possible that be connected between first interface channel 111 and second interface channel 121, in this way, when filling lubricating oil, by
It is in the open state in the first valve port 211, rather than the first valve port could be opened by needing to fill high temperature grease, in systems
In use, filling lubricating oil is relatively simple.
It is pointed out here that small guide vane open the aperture that refers to the aperture of the second valve port 141 compared to the first valve port 211 compared with
It is small, such as in the present embodiment, the distance between the second core portion 32 and the second valve seat 14 and the first core portion 31 and the first valve
The ratio range of the distance between seat 21 are as follows: 1/7-1/4.If 141 aperture of the second valve port is excessive, more lubricating oil will lead to
Gearbox is directly flowed back to by the second valve port 141 and third interface channel 133, only a small amount of or non lubricant oil passes through the first valve
Mouth 211 and second interface channel 121 flow into heat-exchange device, and the effect for filling lubricating oil is relatively poor.
In the present embodiment, since the outer diameter of large-diameter portion 331 is greater than the internal diameter of lug boss 311, this setup can be with
It prevents under certain system requirements, such as the elastic force of the first spring 5 is excessive, and the first valve port 211 is not turned on, but valve
Bar 3 is squeezed into body part 30.By this setup, under filling state, large-diameter portion 331 is abutted against with lug boss 311,
Valve rod 33 cannot further protrude into body part 30, to make the first valve port 211 open by the way that solid state wax 7 is arranged.
Heat control valve state in use is described below, comprising: filling state, the first working condition and the second work shape
State.
As shown in figure 3, under filling state, the solid state wax 7 under solid state is set to the second chamber 62, large-diameter portion 331 with
Lug boss 311 abuts against, and the first valve port 211 is in the open state, and the second valve port 141 is in small guide vane opening.In heat control valve
In use, since the first valve port 211 is in the open state, when heat management system carries out filling lubricating oil, a part of lubricating oil
It can be by being flowed into heat-exchange device behind first interface channel 111 and second interface channel 121.This setup, a side
Lubricating oil filling in face is relatively simple, and also has when filling lubricating oil and hunt leak to heat-exchange device and its connecting line
Function, it is convenient to omit the process additionally hunted leak to heat-exchange device.And hunt leak if it is logical high temperature grease,
Since the temperature of lubricating oil is higher, leak detection risk also can be relatively large.
As shown in fig. 7, in the first operative state, high temperature grease is flowed into from first interface channel 111, at this point, due to
The temperature of high temperature grease is higher, and thermostatic element expanded by heating, body part 30 is moved to 141 side of the second valve port, the second valve port 141
It closes, valve rod 33 is to 2 side motion compresses second spring 4 of end cap after the closing of the second valve port 141.It is pointed out here that if
In closing when two valve ports 141 are under filling state, then when the first working condition of first experience after filling, ontology
Portion 30 is motionless, and valve rod 33 is to 2 side motion compresses second spring 4 of end cap.
If it is the first working condition of first experience after filling, at this point, the heat of lubricating oil is transmitted by inner housing 6
To solid state wax 7, solid state wax 7 is heated to be started to melt, and hardness when solid state wax 7 is under semi-molten state or under molten state becomes
Small, under spring force, the solid state wax 7 of most of semi-molten state or molten state is squeezed into the first chamber 61, small portion
Divide the solid state wax 7 of semi-molten state or molten state to can reside in the second chamber 62.It is small in size after being melted due to solid state wax 7
In the volume of the first chamber 61, the outer diameter that valve rod 33 protrudes into the end of 62 part of the second chamber is greater than the interior of inner wall corresponding to the first chamber 61
Diameter, so most of solid state wax 7 can persistently be placed in the first chamber 61.Due to being provided with sealing ring 91 in inner housing 6, can prevent
Solid state wax 7 is oozed out outside inner housing 6.
As shown in figure 8, in a second operative state, non high temperature lubricating oil is flowed into from first interface channel 111, at this point, hot
Dynamic component shrinkage, body part 30 are moved in the effect of second spring 4 and the restoring force of the first spring 5 to 211 side of the first valve port, the
Two valve ports 141 are opened.
If having undergone the first working condition, most of solid state wax 7 has been placed in the first chamber 61, and valve rod 33 protrudes into inner housing
The distance between end and first step portion 64 of 6 insides reduce, and valve rod 33 protrudes into end and the first step of 6 inside of inner housing
The amount of residual solid state wax 7 between portion 64 seldom can be ignored, and the first core portion 31 is under the elastic force effect of the first spring 5
It is abutted against with the first valve seat 21, the first valve port 211 is closed.In heat control valve, first interface channel 111 and third interface channel
133 connections, first interface channel 111 is not connected to second interface channel 121.
Fig. 9 shows an a kind of embodiment of heat management system, and heat management system includes above-mentioned heat control valve, gearbox 101
With heat-exchange device 102, the wherein outlet in the first interface channel 111 of heat control valve and gearbox 101, third interface channel
133 with the inlet communication of gearbox 101, the inlet communication in second interface channel 121 and heat-exchange device 102, heat-exchange device
102 outlet passes through the inlet communication of the 4th interface channel 134 and third interface channel 133 and gearbox 101.Here should refer to
Out, the outlet of heat-exchange device 102 can also be directly by the inlet communication of pipeline and gearbox 101, and no setting is required at this time the
Four interface channels 134.
When heat control valve is in filling state, the outlet of gearbox passes through the first interface channel 111 and second of heat control valve
The outlet of the inlet communication of interface channel 121 and heat-exchange device 102, heat-exchange device 102 passes through 134 He of the 4th interface channel
The inlet communication of third interface channel 133 and gearbox 101.
