Detailed description of the invention
Clearer for the purpose making the present invention implement, technical scheme and advantage, below in conjunction with in the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, the most identical or class
As label represent same or similar element or there is the element of same or like function.Described embodiment is the present invention
A part of embodiment rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to use
In explaining the present invention, and it is not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into the scope of protection of the invention.Under
Face combines accompanying drawing and is described in detail embodiments of the invention.
In describing the invention, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear",
The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relationship are for based on accompanying drawing institute
The orientation shown or position relationship, be for only for ease of and describe the present invention and simplify description rather than instruction or the dress of hint indication
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protect the present invention
The restriction of scope.
Below in conjunction with the accompanying drawings embodiments of the invention are described in detail, refer to Fig. 1 to Fig. 5；
A kind of governor valve, including: base plate 1 and valve 2, base plate 1 is provided with open slot 3, the shape of open slot 3 is permissible
Being that triangle, rectangle, trapezoidal, circular, oval and swallow-tail form, and quantity are 1 to 10, aperture position can select as required
Select.
Base plate 1 one end is provided with connection ear mount 5, and base plate 1 fixedly mounts with miscellaneous part by connecting ear mount 5.
Open slot 3 is provided with two symmetrical fixed ear bases 4 near the one end connecting ear mount 5, and valve 2 is by installing ear mount 6
Form with valve base plate 7, ear mount 6 is installed and is arranged on one end of valve base plate 7, ear mount 6 cooperation is installed and is arranged on two fixing ears
Between seat 4, it is achieved ear mount 6 is installed and fixed ear base 4 is flexibly connected；Ear mount 6 is installed and fixed ear base 4 selects by bolt even
Connect, it is possible to connected by ball pin；Valve 2 can be made to rotate around the installing hole axis of fixed mounting 4, opening of governor valve 7
Degree size.
The other end of valve base plate 7 is unsettled, and the contour shape of valve base plate 7 is identical with the opening shape of described open slot 3
And valve base plate 7 contour dimension is more than the opening size of open slot 3, both cooperate, and make valve base plate 7 fit completely base plate
When 1, open slot 3 can be sealed.
Valve base plate 7 edge retainer ring geometric pattern reinforcement 8, arranges criss-crossing reinforcing ribs 9 in circulating type reinforcement 8, and
