In being considered as recognizing or imply in any form that the information structure has been the prior art well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of simple and reasonable engine discharging valve, the engine discharging valve is by valve
The cone valve face seal en-hancement of core is ball valve linear sealing, and not high to mach required precision, while pressing tighter, contact surface is small,
It is not easy to wear, seal more reliable.In addition, increased valve element adapter newly, so as to reach reduction setting height(from bottom) so that install what is needed
Locus is substantially reduced, and is conducive to the whole machine of engine to arrange.
To achieve the above object, the invention provides a kind of engine discharging valve, including：Valve body；Water inlet adapter；Valve element,
It includes：Valve ball and mandrel, the valve ball are arranged in the chamber of valve body, and the sealing surface of valve ball is changed into sphere, the valve body tool
There is the conical surface seal face coordinated with the ball face sealing face of the valve ball, the valve body cooperatively forms linear sealing with the valve ball, institute
The one end for stating mandrel is fixedly connected with valve ball；And valve element adapter, its lower end can rotate installed in the another of the mandrel
One end, the upper end of the valve element adapter has pin hole, for installing handle by pin.
Preferably, in above-mentioned technical proposal, valve ball is arranged in the chamber of the valve body by pad.
Preferably, in above-mentioned technical proposal, the other end of mandrel is covered and self-locking spiral shell by clamp nut, locking gasket respectively
Mother is fixed on the valve body.
Preferably, in above-mentioned technical proposal, locking gasket set is U-shaped, and two ends are respectively arranged with spring catch, and the valve element turns
The lower end both sides of joint respectively with spring catch perforate, the valve element adapter by spring catch can rotate installed in described
Locking gasket puts.
Compared with prior art, the present invention has the advantages that：The engine discharging valve is close by the cone valve face of valve element
Envelope is improved to ball valve linear sealing, and not high to mach required precision, while pressing tighter, contact surface is small, not easy to wear, sealing
It is more reliable.In addition, increased valve element adapter newly, so as to reach reduction setting height(from bottom) so that install the locus for needing notable
Reduce, be conducive to the whole machine of engine to arrange.
Brief description of the drawings

Fig. 2 is the right side structural representation of engine discharging valve of the invention.
Fig. 3 is the left view structural representation of engine discharging valve of the invention.
Fig. 4 is the cross section structure diagram in the A-A directions of Fig. 3.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in detail, it is to be understood that guarantor of the invention
Shield scope is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " 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 units
Part or other parts.
As shown in Figures 1 to 4, engine discharging valve according to the specific embodiment of the invention is specifically included：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 is changed into ball
Face, the corresponding sealing surface of valve body 1 is the conical surface, and when valve element is assembled with valve body, after valve body and valve element are compressed, actual contact site is only
Have a line, that is, form linear sealing, the relatively original engine of linear sealing discharge water valve core cone valve face sealing for, to machining
Required precision it is not high, while pressing tighter, contact surface is small, not easy to wear, seal it is more reliable.In addition, valve element adapter 2 is set
In the mandrel outer end of valve element, horizontal level can will be turned to, so as to reach reduction setting height(from bottom) so that the space bit for needing is installed
Put and be substantially reduced, be conducive to the whole machine of engine to arrange.When needing to discharge water, load pin and handle, by 2 turns of valve element adapter
Move and valve body upright position, clockwise or counterclockwise handle.
Specifically, valve body 1 is used to set valve element, and its outer end is connected with into water adapter 3, when discharging valve is installed,
Need to be screwed into the thread segment of adapter 3 of intaking in the part that need to be discharged water, the valve body that discharges water in this process can be with screw thread
It is screwed into and rotates, this means that the installation for needing the space rotated enough to discharging valve just to can guarantee that discharging valve.
As shown in figure 4, valve element includes：Valve ball 11 and mandrel 7, wherein, valve ball 11 is arranged on the chamber of valve body 1 by pad 6
Interior, the sealing surface of valve ball 11 is changed into sphere, and the corresponding sealing surface of valve body 1 is the conical surface, when valve element is assembled with valve body, when valve body and
After valve element is compressed, actual contact site only has a line, that is, form linear sealing, and the relatively original engine of linear sealing discharges water valve core
For the face sealing of cone valve, not high to mach required precision, while pressing tighter, contact surface is small, not easy to wear, and sealing is more
It is reliable.One end of mandrel 7 is fixedly connected with valve ball 11, and the other end covers 4 and self-locking spiral shell by clamp nut 10, locking gasket respectively
Female 8 are fixed on valve body 1.Locking gasket set 4 is U-shaped, and two ends are respectively arranged with spring catch 5, for fixed spool adapter 2.
The lower end both sides of valve element adapter 2 are perforated with spring catch respectively, and upper end has pin hole.Valve element adapter 2 leads to
Cross that spring catch 5 can rotate on locking gasket set 4.During installation, valve element adapter 2 turns to horizontal level, so that
Reach reduction setting height(from bottom) so that the locus that installing needs is substantially reduced, and is conducive to the whole machine of engine to arrange.Work as needs
When discharging water, load pin and handle, valve element adapter 2 is turned to and valve body upright position, clockwise or counterclockwise hand
Handle.
To sum up, the cone valve face seal en-hancement of valve element is ball valve linear sealing by the engine discharging valve, to mach precision
Less demanding, while pressing tighter, contact surface is small, not easy to wear, seals more reliable.In addition, increased valve element adapter newly, so that
Reach reduction setting height(from bottom) so that the locus that installing needs is substantially reduced, and is conducive to the whole machine of engine to arrange.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
