Ask.Traditional automobile cooling system design typically just meets full engine load or the radiating requirements of conventional typical condition, when
Front automobile cooling system not only needs to meet above-mentioned requirements, the most also should improve the comfortableness of car load heating and improve fuel-economy
Property etc..
The car heating of current most tradition is all that the heat utilizing electromotor high temperature coolant out comes occupant
Cabin is heated, and improves client's cold snap comfort.But automobile travels under environment of extremely trembling with fear, due in cooling system
Electromotor, radiator gas removing pipe circulation branch road (water inlet thermostat arrange) has coolant to circulate, thus causes systemic circulation not opened
Qi Qian, coolant participates in peripheral circulation, causes coolant to heat up slack-off, is introduced in the high temperature coolant in crew module's heater
Flow reduces, and the heating effect that may cause crew module is bad, causes the complaint of client.In order to improve the comfortable of car load heating
Property, need to improve electromotor, the design of radiator purge cycle pipeline, reduce the loss of early stage heat of engine, improve combustion simultaneously
Oil economy, thus promote the market competitiveness of automobile.
China Patent No. isCN200910185949.2Patented technology document disclose one " ventilation liquid-preventing stop valve "
Patented technology, its goal of the invention is to provide a kind of ventilation liquid-preventing stop valve, installs a ventilation resistance in electromotor gas removing pipe
Liquid stop valve, it is possible to achieve during electromotor static state, gas is got rid of smoothly, it is ensured that anti-icing fluid fills and prevent anti-icing fluid from sending out smoothly
Motivation gas removing pipe flows to expansion tank, it is to avoid the coolant being available for circulation reduces, and shortens low temperature warm-up period.
Although above-mentioned patent shortens low temperature warm-up period, but can only realize the degasification function of static state, in car load travels,
The coolant of electromotor purge cycle pipeline cannot be recycled to expansion tank, the pressure before engine water pump may be caused little, cause
The operation irregularity of engine water pump, causes the complaint of client.In order to preferably improve the competitiveness of automobile, meet the need in market
Ask, be badly in need of introducing a kind of new valve body structure, to improve the problems referred to above.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, this utility model devises a kind of automobile cooling system flow-limiting valve,
To limit the circulating load of coolant in electromotor, radiator degasification pipeline, thus improve car load heating comfortableness and improve the energy
Utilization ratio.
In order to solve the technical problem of above-mentioned existence, this utility model have employed below scheme:
A kind of automobile cooling system flow-limiting valve, it is characterised in that: include valve body (1), spool and limited post (3), spool
Putting into valve body (1), limited post (3) loads in the fixing hole that valve body (1) is reserved to limit the moving range of spool；Valve body (1)
Be provided with on the fillet surface of endoporus multiple ventilation boss (11) with spool cooperating.
Further, spool is chondritic.
Further, valve body (1), spool and limited post (3) material all use PA66+GF30, injection mo(u)lding.
Further, ventilation boss (11) has four.
Further, this flow-limiting valve is directly installed on inside electromotor gas removing pipe and radiator gas removing pipe.
When resting state or electromotor do not run, spool falls naturally, and the contact internal walls of valve body 1, in whole valve body 1
Circulation area the biggest, it is ensured that the degasification function of electromotor and coolant static state filling.
When electromotor runs, along with the foundation of cooling system pressure, spool can move to fit with valve body 1 endoporus, is formed
One tiny passage, plays metering function, limits the circulation of coolant.But owing to engine-cooling system needs certain
Degasification function, now owing to being designed with ventilation boss 11 on valve body 1, forms the tiny passage of a circle and ensures degasification function, simultaneously
Can meet electromotor, radiator degasification demand, it is ensured that the foundation of cooling system pressure, the work meeting engine water pump is wanted
Ask；In the case of meeting electromotor work requirements, improve the comfortableness of car load heating, improve efficiency of energy utilization.
This automobile cooling system flow-limiting valve has the advantages that
(1) this utility model flow-limiting valve, can play metering function, can meet again electromotor, radiator degasification need simultaneously
Ask, it is ensured that the foundation of cooling system pressure；In the case of meeting electromotor work requirements, improve the comfortableness of car load heating,
Improve efficiency of energy utilization.
(2) this utility model flow-limiting valve simple in construction, compact, dependable performance, can be directly mounted at electromotor, heat radiation
The rubber tubes such as device gas removing pipe are internal to be used, and, ventilation device varies somewhat, and just can mate various vehicle.
(3) this utility model flow-limiting valve is in the case of meeting electromotor work requirements, limits coolant to greatest extent
In electromotor, the circulation of radiator purge cycle branch road, to promote the comfortableness of car load heating, improve the utilization ratio of the energy,
Meet the filling requirement of car load static state simultaneously.
