Further, there is the first holding tank between the first adjacent convex block；There is the second appearance between the second adjacent convex block Receive slot；The gasket is filled in the first holding tank and the second holding tank.

The utility model sets gasket between adjacent liquid stream converts chamber, by gasket there is elastically-deformable characteristic to fill out completely The gap between first flange disk and second flange disk is filled, the leakproofness between liquid stream conversion chamber is further enhanced.

Preferably, there are four third through-hole area on the first flange disk, the big fans such as four third through-hole areas are in Shape is evenly distributed around first flange disk center；It is recessed that the outermost in four third through-hole areas is surrounded with circular third Slot；The second flange disk is equipped with fourth groove Chong Die with third groove；The gasket includes ring part and is connected to ring Cross-shaped formation on the inside of shape portion, the ring part are filled between third groove and the 4th groove；The cross-shaped formation is filled in Between second groove and the first groove；It is interference fitted between the first flange disk, second flange disk and gasket.

In the utility model, the gasket close to sphere of movements for the elephants shape is especially selected, while separating each liquid stream conversion chamber, ring Shape portion can also change chamber and external leakproofness around the outermost of whole liquid stream conversion chambers, enhancement solution circulation.

Preferably, third convex block is also surrounded with outside the third groove；It is convex that third is also surrounded on the outside of 4th groove 4th convex block of block overlapping.Third convex block and the cooperation of the 4th convex block, form the barrier of second sealing, further ensure that product Sealing performance.

Preferably, the third lug surface has multiple circular grooves；4th lug surface is equipped with and circular groove The annular lug of overlapping.

Circular groove and annular lug cooperation, form multiple gas chambers, the first method on the surface of third convex block and the 4th convex block After blue disk and second flange disk are locked, gas chamber can form air barrier, and liquid is avoided to ooze out.
