Description

Milk-vacuum cocks used in milking installations are known, consisting of a base and a butterfly valve. However, the sealing elements in them are quickly worn out.

The proposed milk-vacuum valve differs from the known ones in that in order to reduce the wear of the compacted elements, the mating surfaces of the housing and the butterfly valve have a wave-like surface.

FIG. 1 shows a milk vacuum valve, side view; in fig. 2 - the same, top view; in fig. 3 is the same front view; in fig. 4- connecting handle.

The milk-vacuum valve includes a housing 1 having openings — with a sealing element 2 for connection with the milk line and with a sealing element 3 for connecting with a vacuum line — that are closed by the rotary valve 4.

The shutter is provided with a shaped hole 5 and a hole 6 for the nozzles of the connecting handle 7 and is constantly pressed against the case by a shock absorber 8 through the axis 9 around which it turns. The edges of the housing and the butterfly valve are respectively protrusions 10 and 11, which form a wavy surface.

To turn on the tap, the branch pipes of the connecting handle are inserted into the figured openings of the shutter and, by rotating around an axis, combine the holes of the housing with the branch pipes of the handle. When turning, the lugs of the bolt are located on the lugs of the housing, and the bolt moves away from the sealing elements and will not act on them.

Subject and s.-gain

Milk-vacuum crane for milking machines, consisting of a housing and a butterfly valve, characterized in that, in order to reduce the wear of the sealing elements, the mating surfaces of the housing and the butterfly valve have a wavy surface.
