Abstract

A method and device for temporarily coupling of a hose to a pipe system, where a first coupling part is connected to the hose, and a second coupling part is connected to the pipe system, where both the first and second coupling part comprises valves that automatically closes when said first and second coupling parts are not connected to each other, wherein said first and second coupling part are brought into interaction with each other to establish a tight connection before the valves in the coupling parts are opened and where the coupling parts are locked to each other.

Claims

1. A hose connector comprising:

a first coupling part, the first coupling part comprising;

a first tubular body having a first end and a second end;

a bolt within the first tubular body;

a first valve cone slidably attached to the bolt;

a first valve seat within the first tubular body, the first valve cone biased against the first valve seat; and

a groove formed on an inner surface of the first tubular body between the first end and the first valve cone;

a second coupling part, the second coupling part comprising;

a second tubular body;

a second valve cone;

a second valve seat axially movable and biased against the second valve cone; and

a support ring retaining locking balls on an outer surface of the second tubular body.

2. The hose connector of claim 1, wherein the second tubular body comprises a tubular support member and a base.

3. The hose connector of claim 1, further comprising a first spring biasing the first valve cone against the first valve seat and a second spring biasing the second valve seat against the second valve cone.

4. The hose connector of claim 1, further comprising a locking ring spring biased against the support ring.

5. The hose connector of claim 4, further comprising an actuator axially sliding the locking ring.

6. The hose connector of claim 1, further comprising

a shoulder on the inner surface of the first tubular body, the shoulder engaging the second valve seat, the second valve cone engaging the first valve cone and the locking balls engaging the groove when the first coupling part is connected to the second coupling part.

7. The hose connector of claim 1, further comprising a guiding part connected to the second tubular body and spaced radially outwardly from the second valve seat.

8. The hose connector of claim 1, wherein the first valve cone is within the first tubular body and spaced from the first end of the first tubular body.
