Abstract
The utility model discloses a kind of for the three way cock between expansion tank and electromotor, including three way cock's body, described three way cock's body is T-shaped, it traversing section including there are two interfaces and upper end and the longitudinal section being connected in the middle part of traversing section, the top of described longitudinal section is small-bore section, bottom is heavy caliber section, is the oblique excessive section that upper bore bore little, lower is big between described small-bore section and heavy caliber section；When this utility model uses, the interface of the traversing section of three way cock is connected through sebific duct with engine coolant filler, the interface of longitudinal section is connected through sebific duct with the mouth of a river under expansion tank, during coolant injection, coolant is flowed at water inflow of the engine three way cock through sebific duct at the mouth of a river under expansion tank, during to small-bore section, flow velocity strengthens, pressure diminishes, i.e. pressure reduction becomes big, and coolant injection is easier to, it is easy to improve coolant injection efficiency, it is simple to get rid of the gas in cooling system.
Description
Technical field
This utility model relates to a kind of three way cock, particularly relates to a kind of for the threeway between expansion tank and electromotor
Joint.
Background technology
The low problem that always bus industry exists of coolant filling rate for the first time, after car load rolls off the production line, coolant is typically filling
Fail to fill it up with, after vehicle on road has tried after several times, in addition it is also necessary to add coolant.Reason be exactly coolant filling rate for the first time too
Low.
Summary of the invention
This utility model purpose is: provide a kind of for the three way cock between expansion tank and electromotor, its longitudinal section
Internal diameter is the variable diameter design that external port is big, inner side is little, can accelerate to get rid of the gas in cooling system during filling, improves coolant and adds
Note efficiency.
The technical solution of the utility model is: a kind of for the three way cock between expansion tank and electromotor, including three
Pass joint body, described three way cock's body is T-shaped, it traversing section including there are two interfaces and upper end with in traversing section
Longitudinal section that portion connects, the top of described longitudinal section is small-bore section, bottom is heavy caliber section, described small-bore section and heavy caliber
It it is the oblique excessive section that upper bore bore little, lower is big between Duan.
Preferably, described traversing section is the straight tube that bore is identical, and the bore of this traversing section is more than the maximum caliber of longitudinal section.
Preferably, described traversing section two end interface periphery and longitudinal pars infrasegmentalis interface periphery are respectively formed with a circle flange collar.
Preferably, described three way cock's body is integrated, and its wall thickness is 1.5mm.
Operation principle of the present utility model is: during use, and the interface of the traversing section of three way cock adds with engine coolant
Geat is connected through sebific duct, the interface of longitudinal section is connected through sebific duct with the mouth of a river under expansion tank, and during coolant injection, coolant is from swollen
Being flowed at water inflow of the engine three way cock through sebific duct at the mouth of a river under swollen water tank, during to small-bore section, sectional area reduces, and flow velocity adds
Greatly, according to bernoulli principle p1+1/2 ρ v12+ ρ gh1=p2+1/2 ρ v22+ ρ gh2, highly h1 h2 the same, i.e. flow velocity is the biggest, pressure
Power is the least, i.e. pressure reduction is the biggest, and coolant injection is the easiest, it is simple to improve coolant injection efficiency, it is simple to get rid of in cooling system
Gas.
The utility model has the advantages that: this utility model longitudinal direction section internal diameter is the variable diameter design that external port is big, inner side is little, adds
Can accelerate during note to get rid of the gas in cooling system, improve coolant injection efficiency.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
Fig. 1 is external structure schematic diagram of the present utility model；
Fig. 2 is cross-sectional view of the present utility model.
Wherein: 1 three way cock's body；2 traversing sections；3 longitudinal sections；Small-bore section of 3-1；3-2 heavy caliber section；The oblique mistake of 3-3
Degree section；4 interfaces；5 flange collars.
Detailed description of the invention
Embodiment: as depicted in figs. 1 and 2, a kind of for the three way cock between expansion tank and electromotor, including threeway
Joint body 1, described three way cock's body 1 is T-shaped, it traversing section 2 including having two interfaces 4 and upper end and traversing section 2
Longitudinal section 3 that middle part connects, the top of described longitudinal section 3 is small-bore section of 3-1, bottom is heavy caliber section 3-2, described small-bore
It is oblique excessive section 3-3 that upper bore bore little, lower is big between section 3-1 and heavy caliber section 3-2.Described traversing section 2 is bore phase
Same straight tube, the bore of this traversing section 2 is more than the maximum caliber of longitudinal section 3.
In the present embodiment, 2 liang of end interface 4 peripheries of described traversing section and longitudinal section 3 lower interface 4 periphery are respectively formed with one
Circle flange collar 5.The setting of flange collar 5 so that the assembling of sebific duct and interface 4, and can improve sealing property.
In the present embodiment, described three way cock's body 1 is integrated, and its wall thickness is 1.5mm.
Operation principle of the present utility model is: during use, and the interface of the traversing section of three way cock adds with engine coolant
Geat is connected through sebific duct, the interface of longitudinal section is connected through sebific duct with the mouth of a river under expansion tank, and during coolant injection, coolant is from swollen
Being flowed at water inflow of the engine three way cock through sebific duct at the mouth of a river under swollen water tank, during to small-bore section, sectional area reduces, and flow velocity adds
Greatly, according to bernoulli principle p1+1/2 ρ v12+ ρ gh1=p2+1/2 ρ v22+ ρ gh2, highly h1 h2 the same, i.e. flow velocity is the biggest, pressure
Power is the least, i.e. pressure reduction is the biggest, and coolant injection is the easiest, it is simple to improve coolant injection efficiency, it is simple to get rid of in cooling system
Gas.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limit
System.In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent transformation are formed
Technical scheme, all fall within this utility model claimed within the scope of.
