Description
Technical field
The present invention relates to engine component field, specifically a kind of vented engine water outlet.
Background technology
Outlet pipe is the important composition part of engine-cooling system, and the outlet pipe in existing electromotor is generally included greatly
Circulation pipe, small circulating pipe and warm braw return pipe, the cooling water that engine cylinder-body flows out flow to systemic circulation under the control of thermostat
Pipe or small circulating pipe, warm braw return pipe are for the cooling water that warm braw heat exchanger flows out is delivered in cylinder block passage, traditional
Engine cool closed circuit in systemic circulation pipe, small circulating pipe and warm braw return pipe be separate cooling pipe, it is and cold
But pipeline needs to be attached with sebific duct, and cooling circuit is complicated and leak probability is big, in addition, during automobile use, Jing is normal
Situation full of air in cooling system when can run into cooling water pipe leak or change coolant.If these air not arranged
Go out, engine water temperature can be caused higher, or even " boiling " so that engine interior engine oil viscosity is reduced, engine interior part
Damage is produced due to effectively lubricating, it is therefore necessary to by the air emptying in cooling system.
The exhaust main of cooling system will have two ways at present：A kind of is directly with vaccum-pumping equipment by the sky of cooling system
Gas is drained, and this mode is reliable and quick, but equipment price is expensive, is difficult popularization, is suitable only for enterprise's production and is used.Another kind is to adopt
The mode of artificial filling coolant, coolant is when stream enters cooling system while can manually empty internal air discharge
Gas, this kind of mode are simple and practical, and popularity rate is high, but this exhaust structure only one of which exhaust pathway so that and evacuation time is long,
And coolant can be flowed out from radiator filler with exhaust hose in exhaust process, waste and the environment of coolant are caused
Pollution；And during air-discharging, electromotor is constantly in idling mode, wastes fuel.
Accordingly, it would be desirable to a kind of systemic circulation pipe by engine cooling and circulating system, small circulating pipe become one can
Noncondensing engine outlet pipe, to reduce the quantity of electromotor special purpose parts, makes cooling circuit more simple, and cost is lower, drop
Low cooling system leak probability, at the same be provided with systemic circulation pipe can closed grate hole, effectively can discharge in cooling line
Gas.
The content of the invention
In view of this, the purpose of the present invention is to overcome defect of the prior art, there is provided engine cool is circulated by one kind
The vented engine water outlet that systemic circulation pipe in system, small circulating pipe become one, it is special to reduce electromotor
The quantity of part, makes cooling circuit more simple, and cost is lower, reduces cooling system leak probability, while arranging on systemic circulation pipe
Have can closed grate hole, can effectively discharge the gas in cooling line.
The vented engine water outlet of the present invention, including the systemic circulation pipe and small circulating pipe that interfix；It is described big
The tube wall of circulation pipe is provided with steam vent, and the steam vent is closed by exhaust bolt；
Further, can be by row after exhaust passage and exhaust bolt back-out preseting length are provided with the exhaust bolt
Gas passage makes systemic circulation pipe be in communication with the outside to be exhausted；
Further, the exhaust passage includes the blind hole being axially disposed on exhaust bolt screw rod and is radially communicated in
Through hole outside the blind hole and screw rod；
Further, the systemic circulation pipe entrance point and small circulating pipe entrance point are all connected to a common flange and by the public affairs
Flange is connected with engine cylinder-body altogether；
Further, the end face of the common flange is conformal with cylinder body water-supplying chamber；
Further, the systemic circulation pipe entrance point is connected to the common flange by a pipe joint；The pipe joint shape
Into for containing the cavity of thermostat；
The vented engine water outlet of the present invention also includes being securable on engine cylinder-body and while contains described
The hook of systemic circulation pipe and small circulating pipe.
The invention has the beneficial effects as follows：The vented engine water outlet of the present invention, systemic circulation pipe and small circulating pipe phase
Mutually it is fixed to integration, reduces the exploitation of cooling system special purpose parts, make cooling circuit more simple, cost is lower, reduces cooling
System leak probability, in addition, systemic circulation pipe is provided with steam vent and is closed by exhaust bolt, as cooling system is worked
Easy pneumatosis in journey, and parts of outlet pipe is in engine-cooling system lofty perch, gas is easily accumulated near exhaust bolt,
When electromotor needs aerofluxuss, exhaust bolt of can back-outing is exhausted.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Top views of the Fig. 2 for Fig. 1；
Fig. 3 is the sectional view at A in Fig. 1；
Fig. 4 is the sectional view at B in Fig. 3.
Specific embodiment
Fig. 1 is the structural representation of the present invention.As illustrated, the vented engine water outlet of the present embodiment, including
The systemic circulation pipe for interfixing and 4 small circulating pipes 1；The tube wall of the systemic circulation pipe 4 is provided with steam vent, and the steam vent passes through
Exhaust bolt 7 is closed, and systemic circulation pipe 4 and small circulating pipe 1 interfix integration, reduce the exploitation of cooling system special purpose parts,
Make cooling circuit more simple, cost is lower, reduce cooling system leak probability, in addition, systemic circulation pipe 4 is provided with steam vent simultaneously
Closed by exhaust bolt 7, due to cooling system easy pneumatosis in the course of the work, and parts of outlet pipe is in engine cool
System lofty perch, gas are easily accumulated near exhaust bolt, and when electromotor needs aerofluxuss, exhaust bolt 7 of can back-outing is arranged
Gas.
In the present embodiment, can after exhaust passage and the back-out preseting length of the exhaust bolt 7 are provided with the exhaust bolt 7
Systemic circulation pipe 4 is made to be in communication with the outside by exhaust passage, conventional exhaust screw 7 is entity in the middle of screw, as cooling system exists
Easy pneumatosis in the course of work, and parts of outlet pipe is in engine-cooling system lofty perch, gas is easily accumulated in exhaust bolt 7
Near, when electromotor needs aerofluxuss, the exhaust bolt 7 that needs to back-out completely can just be exhausted, and be carried out after the completion of aerofluxuss again
Tighten, the exhaust bolt 7 of the present embodiment arranges exhaust passage in the screw rod of screw, therefore, only exhaust bolt 7 need to be screwed out one
