Property part can choose spring collar 81(combination Figure 11), spring collar 81 is hole spring collar, and spring collar 81 was fastened on
In the first annular groove 72 for filtering baffle 7, then adopts and filtering baffle 7 is pressed into valve core through hole 421 in a like fashion, until filtering
Baffle 7 is fastened in the second annular groove 73.
On the one hand baffle 7 is filtered in order to facilitate the installation of, on the other hand accidentally falls into glass in order to work as chemical water test device
Facilitate taking-up when in glass cylinder 2, the position of filtering baffle 7 is preferably located at the top of valve core through hole 421, i.e., closer to glass infuser 2.More
Further, filtering baffle 7 can be set at the aperture of valve core through hole 421, and the upper surface for filtering baffle 7 is almost neat with aperture
It is flat.
With reference to Fig. 9 and Figure 10, the sum of the circulation area of several recirculation holes 71 is almost total circulating face of valve core through hole 421
Long-pending 23%-25%, so as to guarantee that aviation fuel can normally circulate.Further, recirculation hole 71 includes the first recirculation hole 711
With the second recirculation hole 712, the first recirculation hole 711 and the second recirculation hole 712 are each provided with three, the first recirculation hole 711 and second
The size of any one recirculation hole 71 in recirculation hole 712 does not allow chemical water test device to pass through；Three the first recirculation holes 711 are
It is formed with the center circumferential array of valve core through hole 421, three the second recirculation holes 712 are equally with the center circumferential of valve core through hole 421
Array forms, and three the second recirculation holes 712 are located at the outside of three the first recirculation holes 711 and interlaced setting.Preferably,
Diameter of the diameter of two recirculation holes 712 less than the first recirculation hole 711.
In an example, the diameter for filtering two end faces up and down of baffle 7 is 24.7mm, three the first recirculation holes 711
Diameter be 7mm, the diameters of three the second recirculation holes 712 is 3mm, filtering baffle 7 with a thickness of 5mm, the slot of the first annular groove 72
Width is 2.4mm, and the groove width of the second annular groove 73 is less than 2.4mm, and each size allows the error there are 0.03mm.
Several recirculation holes 71 are opened up by being configured removable filter baffle 7, and on filtering baffle 7, are not only guaranteed
The normal circulation detection of aviation fuel, additionally it is possible to stop to being fallen accidentally into the chemical water test device in glass infuser, it is detachable
Structure the later period also may be implemented to the maintenance of ball valve core, maintenance；In production, filtering baffle 7 can be produced individually, only
Need to offer one of annular groove inside traditional ball valve core 42, independent filtering baffle 7 of arranging in pairs or groups can solve the problems, such as, be transformed
Cost is relatively low.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
