Embodiment
, below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technological scheme of the present invention.
Fully opened type thermostat of the present invention is simple and reasonable, be arranged on diesel engine temperature saving device seat, by this fully opened type thermostat, the motor short circle is blocked, thereby make engine cooling water all walk major cycle and then cooling water by the hydrodynamic retarder heat exchanger, the retarder exchanger is carried out cooling, thereby guarantee the functional reliability of hydrodynamic retarder.External thermostat is installed additional in car load factory on the whole piece water route in addition, by external thermostat, whole water route is controlled.This standard-sized sheet thermostat boundary dimension is consistent with common thermostat profile, and the structure that need not change original thermostat base, can directly exchange, and is very convenient and practical.
Below detailed description by way of example but unrestriced mode has illustrated the disclosure, should be understood that various aspect of the present disclosure can be by independent realization or the realization of with other aspects, being combined.This specification clearly enables those skilled in the art to make and uses us to believe for new and non-obvious improvement, describe some embodiments, alternative, modification, alternative and system applies, comprised the current best mode that is considered to carry out the inventive principle of describing in this specification.When describing element or feature and/or embodiment, titled with " one " " one " " being somebody's turn to do " and " described ", be intended to represent to have one or more in element or feature.Term " comprises " that " comprising " and " having " is intended to is comprising property, and also has extra element or feature beyond being illustrated in those specifically described elements or feature.
As depicted in figs. 1 and 2, the concrete structure of this fully opened type thermostat comprises: valve seat 1, center-pole 2, adjusting nut 3, connecting body 4, main valve 5 and bypass valve 6, center-pole 2 vertically is laid in valve seat 1, its upper end is located in valve seat 1 top, and by adjusting nut 3 locking that is spirally connected, adjusting nut 3 and center-pole 2.Center-pole 2 lower ends are fixed to connecting body 4 tops, the bottom bracket 41 of valve seat 1 is stretched out in the bottom of connecting body 4, connecting body 4 is with respect to the temperature sensor of existing thermostat, but they are different from existing thermostat temperature sensor structure, its inside does not arrange temperature sensing medium (paraffin), just serves as the rigid connector of center-pole 2 and bypass valve 6.
Traditional thermostat working procedure is: when water temperature lower than 349K(76 ℃) time, exquisite paraffin in the thermostat temperature sensor is solid-state, main valve is closed fully under the effect of spring, make the pathway closure between motor and radiator, and bypass valve is opened fully, directly enter water pump by cylinder head water out through bypass tube, therefore be called short circle.Because water just flows between water pump and water jacket, without radiator, and flow is little, so a little less than intensity of cooling.
When engine water temperature reaches 349K(76 ℃) when above, the paraffin in the thermostat temperature sensor is liquefy gradually, and volume increases thereupon, forces rubber pipe to shrink, thereby the center-pole bottom conical surface is produced thrust upwards.Because the upper end of bar is fixed,, therefore center-pole produces downward reaction thrust to rubber pipe and inductor, overcome spring tension main valve is opened gradually, the bypass valve aperture reduces gradually, and a part of water carries out the major cycle cooling heat dissipation through radiator.
When engine water temperature is elevated to 359K(86 ℃), main valve is opened fully, and bypass valve cuts out fully, and the cooling water radiator of all flowing through, be called major cycle.Due to this moment the flow of cooling water circuit long, flow is large, intensity of cooling is strong.
As shown in Figure 3, fully opened type thermostat of the present invention is installed very simple, installation method and conventional thermostat are as broad as long, the first step first is placed on fully opened type thermostat 7 (fully opened type thermostat 7 is two that are arranged side by side) on water pump 8, bypass valve 6 can first be encountered the short circle backwater hole 81 on water pump, need to buckle Thermolator cover 71 this moment, by Thermolator cover 71, is arranged on fastening fully opened type thermostat 7 on water pump 8.(arrow represents water (flow) direction) as shown in Figure 4, after Thermolator cover 71 fastenings, fully opened type thermostat 7, due to the main valve spring 51 of itself and the active force of case of by-pass valve 61, makes on the bypass valve 6 short circle backwater hole 81 that is pressed in water pump tightly, makes short circle be blocked fully.All current can only all pass through thermostat, then flow out by Thermolator cover 71, thereby make engine cooling water all walk major cycle, and then make cooling water pass through the hydrodynamic retarder heat exchanger, the retarder exchanger is carried out cooling, thereby guarantee the functional reliability of hydrodynamic retarder.External thermostat is installed additional in car load factory on the whole piece water route in addition, by external thermostat, whole water route is controlled.
To sum up, this fully opened type thermostat is simple and reasonable, be arranged on diesel engine temperature saving device seat, by this fully opened type thermostat, the motor short circle is blocked, thereby make engine cooling water all walk major cycle and then cooling water by the hydrodynamic retarder heat exchanger, the retarder exchanger is carried out cooling, thereby guarantee the functional reliability of hydrodynamic retarder.External thermostat is installed additional in car load factory on the whole piece water route in addition, by external thermostat, whole water route is controlled.This standard-sized sheet thermostat boundary dimension is consistent with common thermostat profile, and the structure that need not change original thermostat base, can directly exchange, and is very convenient and practical.
Above disclosed be only several specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
