Abstract

A fluid control valve having a valve trim formed from a geo-polymer-based material so that it is capable of withstanding rapid and extreme thermal shock which can cause damage due to differential expansion of metal components. This invention uses geo-polymer-based materials which will resist damage and can be produced at lower cost with lower embodied energy than the prior art.

Claims

1. A fluid control valve formed at least in part from a geo-polymer-based material.

2. A fluid control valve according to claim 1 comprising a valve body and a fluid control means wherein the body and/or means are formed from a geo-polymer-based material.

3. A fluid control valve according to claim 2 wherein the fluid control means is a valve trim.

4. The fluid control valve according to claim 3 wherein the valve trim is formed from a geo-polymer-based material.

5. The fluid control valve according to claim 4 wherein the geo-polymer-based material includes a fibrous material so as to increase the resistance of the fluid control means to cavitation damage.

6. The fluid control valve according to claim 4 wherein the valve trim is formed from a plurality of valve trim discs.

7. The fluid control valve according to claim 6 wherein the valve trim disc is a resistive disc.

8. The fluid control valve according to claim 7 wherein the resistive disc includes a fluid flow path.

9. The fluid control valve according to claim 2 wherein the geo-polymer-based material includes a hard filler to resist erosion of the fluid control means.

10. The fluid control valve according to claim 2 wherein the geo-polymer-based material includes a resilient filler to resist erosion of the fluid control means.

11. The fluid control valve according to claim 6 wherein the valve trim discs are bonded with a geo-polymer-based adhesive.

12. The fluid control valve according to claim 11 wherein the valve trim discs are sealed over a substantial part of an engagement surface defined by the fluid control means.

13. A valve body for a fluid control valve wherein the body is formed from a geo-polymer-based material.

14. The valve body according to claim 13 wherein the geo-polymer-based material includes a fibre reinforcement.

15. The valve body according to claim 13 wherein the geo-polymer-based material includes a hard filler to resist erosion of the body.

16. The valve body according to claim 13 wherein the geo-polymer-based material includes a resilient filler to resist erosion of the body.
