Axially aligned rotationally adjustable flow control valve
A rotationally adjustable valve is disclosed whereby the user is able to control the flow of fluids from complete shutoff to maximum flow by rotating the adjustment means of the valve, said rotation being axial to the flow of the fluid. Additionally, the user is able to attach high and low pressure test probes directly to the valve, as it is rotatably adjusted, so that additional equipment is not required next to the valve. An embodiment of this invention includes the use of an adjustable Cv disk to set the maximum flow of the valve, rather than just create a simple 180° on/off, very similar to a current 90° ball valve that this device will replace.
1. A valve comprising:
a valve body, an inlet end, and an outlet end, and a bore extending through the inlet end, the valve body, and the outlet end, said valve body defining a longitudinal axis of the valve;
a first disk disposed within the valve body, disposed perpendicularly to the axis, said first disk have a first aperture through which fluid can flow, said first disk being rotationally fixed to the valve body;
a second disk disposed within the bore of the valve body, disposed perpendicularly to the axis, said second disk have a second aperture through which fluid can flow, said second disk being rotatably disposed within the valve body;
a post extending through a slot in the valve body, secured to the second disk, whereby second disk may be rotated within the valve body by movement of the post through the slot; and
a Venturi disposed within the bore of the valve body, a low pressure sensing port communicating from a low pressure region of the Venturi to a first PT port disposed on the valve body, and a high pressure sensing port communicating from a high pressure region of the Venturi to a second PT port disposed on the valve body.
2. The valve of claim 1 , further comprising:
compression means for compressing the first disk and second disk into compressive contact.
3. The valve of claim 1 , further comprising:
a carrier rotatably disposed within the bore of the valve body and rotationally fixed to the second disk.
4. The valve of claim 3 , wherein:
a carrier is rotationally fixed to the post, and disposed between the post and the second disk.
5. The valve of claim 1 , further comprising:
an interior bore wall rotationally fixed to the valve, said interior bore wall having at least one longitudinally oriented slot, wherein the first disk comprises at least one longitudinally extending locking tab sized and dimensioned to fit into the longitudinally oriented slot, whereby rotation of the first disk within the valve is prevented.
6. A valve comprising:
a valve body, an inlet end, and an outlet end, and a bore extending through the inlet end, the valve body, and the outlet end, said valve body defining a longitudinal axis of the valve;
a first disk disposed within the valve body, disposed perpendicularly to the axis, said first disk have a first aperture through which fluid can flow, said first disk being rotationally fixed to the valve body;
a second disk disposed within the bore of the valve body, disposed perpendicularly to the axis, said second disk have a second aperture through which fluid can flow, said second disk being rotatably disposed within the valve body;
a post extending through a slot in the valve body, secured to the second disk, whereby second disk may be rotated within the valve body by movement of the post through the slot; and
a piezometer ring disposed in the bore of the valve body.
7. The valve of claim 6 , further comprising:
compression means for compressing the first disk and second disk into compressive contact.
8. The valve of claim 6 , further comprising:
a carrier rotatably disposed within the bore of the valve body and rotationally fixed to the second disk.
9. The valve of claim 8 , wherein:
a carrier is rotationally fixed to the post, and disposed between the post and the second disk.
10. The valve of claim 6 , further comprising:
an interior bore wall rotationally fixed to the valve, said interior bore wall having at least one longitudinally oriented slot, wherein the first disk comprises at least one longitudinally extending locking tab sized and dimensioned to fit into the longitudinally oriented slot, whereby rotation of the first disk within the valve is prevented.
