Effect.Meanwhile inner space is collectively formed in outer housing 501b-1 and the first cover closing member 501b-2, the second cover closing member 501b-3.The
One cover closing member 501b-2 and the second cover closing member 501b-3 overall structures are identical, are cover board shape, and the two is symmetrical arranged, and solid respectively
Due to the both ends of valve body 501b.First cover closing member 501b-2 and the second cover closing member 501b-3 includes cover board F-1 and branch F-
2, cover board F-1 are main body portion, and branch F-2 is vertically installed in the medial surface of cover board F-1.
Further, the first separator 501b-4 and the second separator 501b-5 structures are identical, are plate, the two
The inside of outer housing 501b-1 is symmetrical arranged and is supported in, edge and the madial wall of outer housing 501b-1 mutually fit, and are formed
Sealing.Meanwhile there is convex block on the madial wall of outer housing 501b-1, it is set to the middle area on outer housing 501b-1 madial walls
Section, and around one circle of its medial surface setting.First separator 501b-4 and the second separator 501b-5 are capped part 501b- respectively
2 branch F-2 is pressed on the both ends of convex block.Finally, the first cover closing member 501b-2 and the second cover closing member 501b-3 by bolt with
The edges at two ends of outer housing 501b-1 is fixedly connected.
It can be seen from the above, outer housing 501b-1 and the connection of the first cover closing member 501b-2, the second cover closing member 501b-3 are formed
Internal whole confined space, and this space is divided by the setting of the first separator 501b-4 and the second separator 501b-5 again
Three subregions, respectively the firstth area, the secondth area and third area.Wherein, the first cover closing member 501b-2 and the first separator 501b-4
Between be the firstth area；It is the secondth area between first separator 501b-4 and the second separator 501b-5；Second separator 501b-5
It is third area between the second cover closing member 501b-3.In addition, it is opened on the first separator 501b-4 and the second separator 501b-5
Equipped with through-hole K.
Further, force piece 501a includes cylinder 501a-1 and connecting rod 501a-2, the wherein end face of cylinder 501a-1
