Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention will be further described.
As shown in Figure 1, valve body 1 is placed on level ground, and the valve chamber bilateral symmetry of valve body 1, and cavity bottom is in a left side
The trumpet type that the right side extends out, and axis is located at horizontal direction, and installs symmetrical left 2 He of valve seat in the root of loudspeaker profile
Right valve seat 7.
Left valve seat 2 is identical with right 7 structure of valve seat, and main body is cylinder, and outer surface is machined with installation step.Pass through step structure
It is stuck in the cavity of valve body 1.
Left flashboard 3 and right flashboard 6 are installed between left valve 2 and right valve seat 7, and symmetrically fixed.
It is shown in Fig. 1, left flashboard 3 and right flashboard 6 are installed by flashboard frame 4 and lower wedge block 5.
The flashboard frame 4 is fixedly mounted by being fixed on the lower wedge block 5 of 1 cavity bottom of valve body, flashboard frame 4, lower wedge block
5, left flashboard 3 and right flashboard 6 form flashboard assembly.
It is machined with guiding rib 8 on flashboard frame 4, guide groove 9 is machined on 1 cavity of valve body, guiding rib 8 is oriented to corresponding
Slot 9 cooperates, and when valve is during opening and closing, by media impingement is run in valve chamber, guiding rib 8 is contacted with guide groove 9,
Flashboard assembly is by guiding rib 8 along linear motion above and below doing in guide groove.
The structure is utilized the guiding rib of institute's band on flashboard frame and is in contact with the slot on valve body cooperation, so that flashboard assembly exists
It is always ensured that during valve opening and closing and does linear motion up and down in guide groove, flashboard assembly opening-closing process stability is good, mentions
The high reliability of valve opening and closing.
Guiding rib 8 is vertical direction, and quantity can be 2,4,6 and 8.
Corresponding guide groove 9 is vertical direction, and quantity can be 2,4,6 and 8.
The flashboard frame 4 is fixedly mounted at the central axis of 1 vertical direction of valve body, i.e., flashboard frame 4 and valve body 1 are vertical
Direction is co-axially mounted.
Guiding rib 8 is distributed along the vertical axial even circumferential of flashboard frame 4.
In addition the guiding rib 8 in the present apparatus can be plate profile structure, i.e. thickness identical half structure up and down, and corresponding lead
The rectangular duct of consistency of thickness is also processed into slot 9.
Above-mentioned plate profile structure can be processed into the structure that side is vertical direction, can also be processed into inclined-plane, such phase
Inclined-plane is processed into the bottom for the guide groove 9 answered, and the inclined-plane of the side of 9 bottom bevel of guide groove and guiding rib 8 matches, and forms wedge
The close guide frame of shape.To drive flashboard is reliable and stable to move up and down.
