Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figures 1 to 4, specifically including according to the engine discharging valve of the utility model embodiment：Valve
Body 1, valve element, water inlet adapter 3 and valve element adapter 2.Wherein, valve element is arranged in valve body 1, and valve element is ball valve, and its sealing surface becomes
For sphere, the corresponding sealing surface of valve body 1 is the conical surface, when valve element is assembled with valve body, after valve body and valve element compression, actual contact site
Position only has a line, that is, forms linear sealing, the relatively original engine of linear sealing discharge water valve core cone valve face sealing for, to machine
The required precision of processing is not high, while pressing tighter, contact surface is small, not easy to wear, seals more reliable.In addition, valve element adapter 2
