"Milk valve"

The innovation concerns a milk valve to maintain the Vacuum in the milk lines of milking devices when a milking cluster attached for milking falls off

If one or more teat cups failed while a cow was being milked so much air is sucked into the milking system through this milking cluster that the vacuum drops sharply. Are if further milking clusters are connected, they too are no longer held on the udder by the low vacuum and they are also fall off.

All milking clusters must then first be disconnected from the milking system so that no more air can flow into the milking device and the vacuum required for milking from the vacuum pump can be restored · Only then do the milking clusters know be started again and thus the interrupted milking process can be continued again. In addition to the loss of time, the night * part of the fact that the interrupted flow of milk is very unhealthy for the cow's udder

In order to remedy these disadvantages, it is known to arrange a Mileh valve in a collecting stack. When air enters the cluster, the mileh valve closes and the valve spindle emerges from the claw. If the cluster falls, the cluster can fall onto the valve spindle and the valve is opened again.

The task of the innovation is to avoid these known disadvantages · », and a milk valve to reveal which one falls of the milking cluster attached to it is not opened again. For this purpose, the innovation is characterized in that the Milehventil one with the milk connector or with the collecting piece

has connected inlet, and that the outlet of the milk valve is connected to the milk line or to the milking bucket. Am Another feature of the innovation is that the milk valve consists of a chamber provided with an inlet and an outlet, in which has a double valve between the inlet and the outlet.

An embodiment of the innovation is shown schematically in the drawings.

Show it:

Fig. 1 the Milehventil in a bucket milking device, 2 the milk valve in the milk hose, 3 shows the Mileh valve in section.

There is a vacuum of approx. 50% in valve 1. Due to the atmospheric Pressure is the outer valve disk 2 against the valve: printed. The double valve 3 remains open and the milk can unhindered from the inlet 4 through the MilcLventil 1 in the Outlet S.

If one or more teat cups fail, it is reduced see the difference between the internal pressure in valve 1 and the atmospheric pressure that presses on the outer valve disk. The outer valve disk 2 is therefore no longer so solid printed against the valve housing 7. In addition, the air that has penetrated the Milehsehlaueh hits the inner one with the milk Valve disk 8 and thus closes the valve 1 · It can therefore no more air is sucked through the milking cluster

Only the outer valve disk 2 is required for further milking are pressed against the valve housing 7. After attaching the teat cups β, milking can continue immediately To wind the milking device, the outer valve plate 2 is rotated by approx * 90 ° and thus the double valve 3 with the bayonet lock 14 locked · This means that valve 1 remains open despite the turbulent flow, and the cleaning fluid can

flow unhindered through the handlebar device. This guarantees perfect cleaning.

The milk valve 1 is between the Milchsammeistück 9 and dm Milking bucket 10 or between the piece of milk saramel 9 and the milk line 11. The milk hose 12 therefore becomes safe "!" Blocked if one or more teat cups 6 knocked off during milking will.
