Abstract

A dielectric regulator comprises a regulator and an inlet group. The inlet group comprises: an inlet nozzle assembly and an inlet fitting. The inlet nozzle assembly comprises: a nozzle, a bushing, a first sealing ring, a second sealing ring, a nut, a first dielectric interface, and a second dielectric interface. The nozzle defines a sealing block void, a funnel void, a first cylindrical void, and a polygonal void. The bushing surrounds the nozzle and compresses the first sealing ring between the nozzle and the bushing. The second sealing ring surrounds the nozzle and compressed via the nozzle and the bushing. The first dielectric interface is ring-shaped and is compressed via the nut and the nozzle. The second dielectric interface is ring shaped and is compressed via the nozzle and the inlet fitting. The inlet fitting defines a central void and is threadably engaged with the nozzle assembly via the nut.

First claim

The invention claimed is:

1. A dielectric regulator comprising:
a regulator comprising:
a body having an inlet; and
a sealing tip disposed in the inlet; and

an inlet group comprising:
an inlet nozzle assembly disposed in the inlet to selectively engage with the sealing tip, the inlet nozzle assembly comprising:
a nozzle defining a sealing block void, a funnel void, a first cylindrical void, and a polygonal void;
a bushing surrounding a first outer perimeter of the nozzle;
a first sealing ring compressed between the first outer perimeter of the nozzle and the bushing;
a second sealing ring surrounding a second outer perimeter of the nozzle and compressively contacting the second outer perimeter and the bushing;
a nut rotatably disposed about the nozzle;
a first ring-shaped dielectric interface configured to be compressed between the nut and the nozzle; and
a second ring-shaped dielectric interface in contact with the first ring-shaped dielectric interface; and

an inlet fitting defining a central void and threadably attached to the nozzle via the nut, the inlet fitting to compress the second ring-shaped dielectric interface against the nozzle and the first ring-shaped dielectric interface.

2. The dielectric regulator of claim 1 , wherein the inlet group is configured to deliver fluid at a variable pressure and flow rate to the regulator and the regulator is configured to deliver fluid at a constant pressure.

3. The dielectric regulator of claim 1 , wherein the regulator abuts the bushing to compress the first sealing ring.

4. The dielectric regulator of claim 1 , wherein the second sealing ring is in compressive contact with the regulator.

5. The dielectric regulator of claim 1 , wherein the first dielectric interface and the second dielectric interface electrically insulate the nut and the nozzle.

6. The dielectric regulator of claim 1 , wherein the first dielectric interface includes a first portion, a second portion, and a third portion, the first portion being narrower than the third portion, the second portion forming a transitional flange between the first portion and the third portion and being compressed between the nut and a shoulder of the nozzle.

7. The dielectric regulator of claim 1 , wherein the polygonal void is configured to receive a tool to threadably engage the nozzle with the body.

8. A dielectric regulator comprising:
a regulator comprising:
a body having an inlet; and
a sealing tip disposed in the inlet; and

an inlet group comprising:
a nozzle assembly disposed in the inlet, selectively engaged with the sealing tip, and comprising:
a nozzle having a shoulder;
a first dielectric interface about the nozzle and engaged with the shoulder;
a nut about the first dielectric interface, the nut compressing the first dielectric interface against the shoulder; and
a second dielectric interface disposed in the nut and in contact with the first dielectric interface; and

an inlet fitting threadably engaged with the nut and compressing the second dielectric interface against the nozzle and the first dielectric interface.

9. The dielectric regulator of claim 8 , wherein the nozzle assembly comprises a first sealing ring about the nozzle and a bushing about the nozzle and compressively engaged with the first sealing ring.

10. The dielectric regulator of claim 9 , wherein the nozzle has a second shoulder, the bushing being engaged with the second shoulder.

11. The dielectric regulator of claim 9 , wherein the regulator abuts the bushing to compress the first sealing ring.

12. The dielectric regulator of claim 9 , wherein the nozzle assembly comprises a second sealing ring about the nozzle and compressively engaged with the regulator and the bushing.

13. The dielectric regulator of claim 8 , wherein the first dielectric interface and the second dielectric interface electrically insulate the nut and the nozzle.

14. The dielectric regulator of claim 8 , wherein the nozzle has a polygonal void in fluid communication with the inlet fitting and a funnel void in fluid communication with the polygonal void and with the sealing tip.

15. A dielectric regulator comprising:
a regulator to regulate fluid flow comprising:
a body having an inlet; and
a sealing tip disposed in the body; and

a nozzle assembly partially disposed in the inlet to selectively engage with the sealing tip, the nozzle assembly comprising:
a nozzle having a funnel void;
first and second dielectric interfaces engaged with one another and the nozzle;
a nut rotatably engaged with the first dielectric interface, the second dielectric interface being disposed in the nut; and

an inlet fitting threadably engaged with the nut to compress the first and second dielectric interfaces against the nozzle and in fluid communication with the inlet via the funnel void.

16. The dielectric regulator of claim 15 , wherein the funnel void has a tip void portion and a cone void portion, the tip void portion being disposed deeper in the inlet than the cone void portion.

17. The dielectric regulator of claim 15 , wherein the nozzle is configured to receive a tool to threadably engage the nozzle with the body.

18. The dielectric regulator of claim 15 , wherein the nozzle assembly comprises first and second sealing rings about the nozzle and a bushing about the first sealing ring.

19. The dielectric regulator of claim 18 , wherein the bushing abuts the regulator to compress the first sealing ring and the second sealing ring is compressed between the regulator, the nozzle, and the bushing.

20. The dielectric regulator of claim 15 , wherein the first and second dielectric interfaces electrically insulate the nozzle from the inlet fitting and from the nut.
