Description
Technical field
This utility model relates to a kind of thermoregulator, especially relates to the multistage open-type thermoregulator of a kind of employing.
Background technology
Current common thermoregulator structure includes valve, support, spool, valve seat, spring and sealing member.When engine temperature is increased to and just opens more than temperature, induction apparatus pushrod movement also drives valve opening, makes part coolant enter systemic circulation heat radiation.Along with engine temperature continues to raise, valve continues on, and coolant rate strengthens, and heat radiation is strengthened, and when valve reaches full-gear, the flow of systemic circulation reaches maximum, and cooling system heat-sinking capability reaches capacity, and engine temperature begins to decline.Decline along with engine temperature; induction apparatus push rod starts to fall after rise under the action of the spring, and valve progressively closes off, by the coolant rate of systemic circulation also with reduction; engine cooling slows; when engine temperature continues to reduce, push rod continues to fall after rise, until valve completely closes; by the dynamic adjustment of a period of time; engine temperature fluctuates up and down in certain suitable temperature ranges, will not be too high without too low, thus protecting the purpose of electromotor.
Along with the raising people of material life are more and more higher to the requirement of thermoregulator, particularly in commercial car, open temperature at the beginning of conventional thermoregulator and be generally nominal temperature ± 2 DEG C, standard-sized sheet temperature is generally high 12～15 DEG C than nominal temperature, the requirement (it is little that default flows opened by thermoregulator, the requirement that standard-sized sheet flow is big) of commercial car cannot be met.
Utility model content
In order to solve above-mentioned technical problem, it is little that this utility model provides one just to open flow, it is possible to the multistage open-type thermoregulator of employing of precision controlling cooling liquid flow.
The technical solution adopted in the utility model is: the multistage open-type thermoregulator of a kind of employing, including the cavity surrounded by support, the top of described cavity is provided with coolant systemic circulation path, the bottom of described cavity is provided with coolant partial circulating path, it is characterized in that: go up parallel connection in described cavity in the axial direction and be provided with two and above induction apparatus, described cavity upper end and coolant systemic circulation path correspondence position are equipped with valve seat, described each induction apparatus upper end and coolant systemic circulation path correspondence position are connected to valve each through push rod, described valve and valve seat cooperate and can control the break-make of coolant systemic circulation path；Described each induction apparatus lower end is arranged on support each through spring, described each induction apparatus is experienced temperature end and is all extend in coolant partial circulating path, being equipped with the expanding material that can experience oil temperature change in described each induction apparatus, the intumescent material swells performance of described each induction apparatus is all different.
As preferably, the number of described induction apparatus is three.
As preferably, opening temperature at the beginning of described valve and all differ.
This utility model obtains and provides the benefit that: this utility model is by adopting multistage open-type thermoregulator, multiple induction apparatus it is arranged in parallel in a thermoregulator, and arrange different first open temperature by adjusting induction apparatus expansion character so that thermoregulator is capable of the unlatching step by step of respective valves in the process experience ECT.Opening flow at the beginning of this thermoregulator less, faster, homoiothermic is more accurate for engine warms.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but content of the present utility model is not limited solely to the following examples.
As Figure 1-3, the multistage open-type thermoregulator of a kind of employing of the present utility model, including the cavity surrounded by support 2, the top of cavity is provided with coolant systemic circulation path, the bottom of cavity is provided with coolant partial circulating path, engine coolant is divided into two-way in thermoregulator, a road and coolant systemic circulation communication, another road and coolant partial circulating communication；Upper in the axial direction in cavity is that equal subangle in-parallel is provided with two and above induction apparatus 3, cavity upper end and coolant systemic circulation path corresponding position are equipped with valve seat 4, each induction apparatus 3 upper end is connected to valve 1 with coolant systemic circulation path corresponding position by push rod, and valve 1 and valve seat 4 cooperate and control the break-make of coolant systemic circulation path；Each induction apparatus 3 is arranged on support 2 by spring 5, the impression temperature end of each induction apparatus 3 all extend in coolant partial circulating path, for experiencing the change of the coolant temperature in coolant partial circulating path, the expanding material that can experience coolant temperature change it is equipped with in each induction apparatus 3, expanding material performance in each induction apparatus 3 all differs, just open the expanding material that the low valve correspondence coefficient of expansion of temperature is higher, when coolant temperature changes, multistage unlatching can be realized.
When the coolant temperature in engine coolant circuit raises, induction apparatus 3 experiences the high temperature coolant in partial circulating path, in induction apparatus 3, expanding material expands immediately, just open the relatively low valve of temperature 1 to separate with valve seat 4 gradually under the drive of induction apparatus 3 push rod, corresponding valve 1 is opened gradually, coolant systemic circulation path is opened step by step, corresponding spring 5 is compressed, when coolant temperature raises further, just open the higher valve of temperature 1 to open step by step, until all valves 1 are all opened, coolant systemic circulation path fully opens；Otherwise, when oil temperature reduces, valve 1 is closed step by step, and coolant systemic circulation path completely closes.
As in Figure 2-4, for an embodiment of the present utility model.The program adopts three induction apparatus (A, B, C) relative angles to be that 60 DEG C of in-parallels are arranged, and three induction apparatuss are fixed together by support 2, set the first of three induction apparatuss and open temperature respectively 70 DEG C, 80 DEG C, 90 DEG C.
When ECT is increased to 70 DEG C, induction apparatus 3 experiences the coolant temperature in coolant partial circulating path, intumescent material swells, induction apparatus A drives corresponding valve 1 to separate with valve seat 4 by push rod, its corresponding spring 5 is compressed, valve 1 corresponding for induction apparatus A is opened gradually, and coolant systemic circulation path is gradually opened；When oil temperature further rises to 80 DEG C, valve 1 corresponding for induction apparatus B is opened gradually；When coolant temperature further rises to 90 DEG C, valve 1 corresponding for induction apparatus C is opened gradually, and when the valve 1 that induction apparatus A, B, C are corresponding is all opened, coolant systemic circulation path is fully opened, and then realizes the unlatching step by step of thermoregulator.Otherwise, when coolant temperature is reduced to 90 DEG C, 80 DEG C, 70 DEG C, the valve 1 that induction apparatus A, B, C are corresponding is closed step by step, and namely coolant systemic circulation path is closed step by step.
This thermoregulator is compared with existing thermoregulator, replaced to by one group of induction apparatus and at the beginning of three groups, open the induction apparatus that temperature differs, make at the beginning of thermoregulator, to open flow less, and control more accurate by the flow of thermoregulator with the flow in process of coolant temperature change in coolant partial circulating.
