Description
Technical field
The utility model relates to the engine-cooling system technical field, especially relates to a kind of engine thermostat base assembly.
Background technique
Thermostat base is the vitals in the engine-cooling system.Thermostat base and thermostat housing form thermostat, and thermostat connects the pump circulation water cooling system of automobile radiators, water pump, cylinder cover water jacket formation motor car engine.
Existing thermostat base is to be assemblied in Cooling of Cylinder Head liquid outlet pipe place, cylinder cap water outlet and thermostat base is realized being connected with clip by rubber hose; Pump water inlet will be assemblied on the thermostat base, also is by rubber hose and clip connected between short circle hole and the pump water inlet.
There is following problem in existing thermostat base:
1, traditional thermostat base makes pipeline complexity in the cooling system, and connecting hose is many, clip is many, and it is large to take arrangement space, is unfavorable for the automobile front chamber layout;
2, hose clamp connects, and the cooling liquid leakage phenomenon easily occurs, and needs to install antifriction net for preventing that flexible pipe from interfering, and increases cost;
3, flexible pipe connects, and for preventing interfering and satisfied temperature field arrangement requirement, the flexible pipe bending part is many, and cooling system cooling liquid internal resistance is large;
4, assembly process is various, and maintainalbility is poor.
The model utility content
Technical problem to be solved in the utility model provides a kind of engine thermostat base assembly, and to reach the part of cooling system compact structure, it is little to take up room, the purpose that connection sealing is good.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of engine thermostat base assembly, comprise the thermostat pedestal, described thermostat pedestal is provided with thermostat adpting flange and radiator water outlet mouthpiece, also is provided with pump intake adpting flange and cylinder cap osculum adpting flange on the described thermostat pedestal.
Be through with the water feeding of water pump pipeline between the inherent radiator water outlet mouthpiece of described thermostat pedestal and the pump intake adpting flange.
Be communicated with by the short circle hole between described thermostat adpting flange and the water feeding of water pump pipeline, be communicated with thermostat cavity attachment hole by the cylinder cap water outlet between thermostat adpting flange and the cylinder cap osculum adpting flange.
Described pump intake adpting flange, cylinder cap osculum adpting flange, thermostat adpting flange seal by flange gasket when connecting.
The utility model compared with prior art, have the following advantages: this thermostat pedestal is integrated cylinder cap osculum adpting flange, pump intake adpting flange, and section is integrated within it water feeding of water pump pipeline and short circle pipeline, reduced the use of flexible pipe and clip connected structure, make the part of cooling system compact structure, it is little to take up room, and the coolant flow resistance is little in the cooling system; Flange connects, and good sealing effect is not prone to the cooling liquid leakage phenomenon, and is easy to maintenance.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model thermostat base assembly organigram.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the sectional view along A-A among Fig. 2.
Fig. 4 is the sectional view along B-B among Fig. 2.
Among the figure: 1. thermostat pedestal, 2. radiator water outlet mouthpiece, 3. pump intake adpting flange, 4. cylinder cap osculum adpting flange, 5. thermostat adpting flange, 6. short circle hole, 7. cylinder cap water outlet and thermostat cavity attachment hole, 8. water feeding of water pump pipeline; Dotted arrow represents that the short circle cooling liquid flows to, solid arrow represents that the major cycle cooling liquid flows to.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of engine thermostat base assembly comprises thermostat pedestal 1, is provided with thermostat adpting flange 5, radiator water outlet mouthpiece 2, pump intake adpting flange 3 and cylinder cap osculum adpting flange 4 at thermostat pedestal 1, it is integrated, connect by flange, reduce the use of flexible pipe and clip connected structure, make the part of cooling system compact structure, it is little to take up room, good sealing effect is not prone to the cooling liquid leakage phenomenon, and is easy to maintenance.
Further, be through with water feeding of water pump pipeline 8 between thermostat pedestal 1 inherent radiator water outlet mouthpiece 2 and the pump intake adpting flange 3, reduce the use of flexible pipe and clip connected structure.
As shown in Figure 3 and Figure 4, be communicated with by short circle hole 6 between thermostat adpting flange 5 and the water feeding of water pump pipeline 8, be communicated with thermostat cavity attachment hole 7 by the cylinder cap water outlet between thermostat adpting flange 5 and the cylinder cap osculum adpting flange 4, realize that the cooling liquid short circle is got back to water pump or radiator is arrived in the cooling liquid major cycle, the parts such as traditional short circle connecting hose and clip have been saved, be convenient to maintenance, the layout of complete machine is also more rationally attractive in appearance.
Wherein, when pump intake adpting flange 3 and pump intake, cylinder cap osculum adpting flange 4 and cylinder cap osculum, thermostat adpting flange 5 are connected with thermostat housing, all seal by flange gasket, avoid poorly sealed, the cooling liquid leakage phenomenon occurring occurs, and flange connects also and connects long service life than flexible pipe, and good operating stability is saved maintenance cost simultaneously.
Dotted arrow among Fig. 3 represents that the short circle cooling liquid flows to.In engine start or low load operation stage, coolant temperature is lower, the circulation cooling liquid by the cylinder cap osculum out after, enter in the cavity of thermostat pedestal through cylinder cap water outlet and thermostat cavity attachment hole, because this moment, thermostat was in closed condition, so cooling liquid can't enter radiator inleting pipe by thermostat, can only enter the water feeding of water pump pipeline via the short circle hole, and process pump intake adpting flange enters water pump, the short circle of realization cooling system.
Solid arrow among Fig. 4 represents that the major cycle cooling liquid flows to.When engine load increases, during COOLANT TEMPERATURE, thermostat will be opened, and the short circle hole blocked, this moment cooling liquid by the cylinder cap osculum out after, to enter in the cavity of thermostat pedestal via cylinder cap water outlet and thermostat cavity attachment hole, the thermostat of this moment is in opening state, so cooling liquid enters thermostat by the thermostat adpting flange, and finally enter radiator by radiator inleting pipe, reach the effect to the cooling liquid cooling, guarantee the normal operation of motor, realize the major cycle of cooling system.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
