Abstract

The present invention proposes a device for controlling discharge by a conduit. The device comprises a body, a mouth or a first portion attached to the body and a needle or a second portion attached to the body. The mouth and the needle are coaxial. The mouth receives an end portion of the conduit, such that when A received, an internal surface of the mouth is in contact with an external portion of the end portion of the conduit. The needle is arranged to be inserted into the received end portion of the conduit, such that an external surface of the needle is in contact with an internal surface of the end portion of the conduit.

Claims

1. A device for controlling discharge by a conduit, comprising:

a first portion attached to a body of the device, the first portion arranged to be coupled to an end portion of the conduit by receiving the end portion of the conduit, wherein when coupled, an internal surface of the first portion is in contact with an external surface of the end portion of the conduit;

a second portion attached to the body of the device, the second portion and the first portion being coaxial, the second portion positioned downstream along the direction of movement of the end portion of the conduit for coupling the first portion to the end portion of the conduit, and wherein the second portion is arranged to be inserted into the end portion of the conduit when the first portion and the end portion of the conduit are coupled, such that when inserted, an external surface of the second portion is in contact with an internal surface of the end portion of the conduit;

wherein when the first portion is coupled to the end portion of the conduit, the end portion of the conduit is disposed between the internal surface of the first portion and the external surface of the second portion, controlling discharge by the conduit.

2. The device as claimed in claim 1, wherein the first portion is a cylinder with a first axis.

3. The device as claimed in claim 2, wherein the second portion is a conical needle with a second axis.

4. The device as claimed in claim 2, wherein the internal surface of the first portion comprises a fastening arrangement.

5. The device as claimed in claim 4, wherein the fastening arrangement comprises threads.

6. The device as claimed in claim 1, wherein the first portion, second portion and the body of the device is composed of polymer.

7. The device as claimed in claim 6, wherein the polymer is polypropylene plastic.

8. The device as claimed in claim 6, wherein the first portion, second portion and the body of the device is embedded with a metal-based material.

9. The device as claimed in claim 8, wherein the metal-based material is one of a metal and an alloy.

10. The device as claimed in claim 9, wherein the alloy is mild steel.

11. A method of manufacturing a device for controlling discharge by a conduit, the device comprising a body, a first portion attached to the body and a second portion attached to the body, wherein the first portion and the second portion being coaxial;

the method comprising the steps of;

conducting a first moulding operation using polymer to produce a first block of the device, the first moulding operation producing a set of hollow portions in the first block;

inserting a set of metal-based material components into the set of hollow portions; and

conducting a second moulding operation using polymer to produce a second block of the device, the second block moulded over the first block wherein the set of metal-based material components inserted into the set of hollow portions in the first block are covered by the second block.
