Abstract
A system and method for coupling valve components, especially for attaching an actuator to a valve body. A first component defines a circumferential groove in its exterior surface with an aperture or recess in the bottom wall of the groove. A second component has a corresponding circumferential groove defined in its inner surface. An aperture extends through from the exterior surface of the second component into the circumferential groove. During assembly, the second component is received over the first component with the circumferential grooves aligned. The hooked end of a flexible plastic rod is inserted through the aperture of the second component and engaged in the aperture or recess in the first component. The second component is then rotated relative to the first component to draw the plastic rod into the grooves.
Claims
1. A valve comprising: a body portion including a cylindrical wall structure having an outer surface defining a first circumferential groove therein, the first circumferential groove presenting a back wall with a recess defined therein; a cap portion having a cylindrical outer wall and an inner wall spaced apart and concentric with the outer wall, the outer wall and inner wall defining a recess therebetween for receiving the cylindrical wall structure of the body portion, the outer wall defining a second circumferential groove facing into the recess and at least one aperture extending from an outer surface of the outer wall into the second circumferential groove; and an elongate plastic rod presenting a pair of opposing ends, wherein the cap portion is selectively operably couplable to the body portion by first engaging the cylindrical wall structure of the body portion in the recess of the cap portion with the first and second circumferential grooves in registry and the recess of the body portion registered with the at least one aperture in the cap portion, inserting one of the opposing ends of the plastic rod through the at least one aperture into the recess of the body portion, and rotating the cap portion to draw the plastic rod into the first and second circumferential grooves to a fully assembled state wherein the plastic rod extends substantially circumferentially around the body portion in the first circumferential groove and also in the second circumferential groove of the cap portion, said second circumferential groove concentric with the first circumferential groove whereby the elongate plastic rod has a substantially circular shape and secures the cap portion on the body portion.
2. The valve of claim 1 , wherein the aperture in the cap portion is oblong.
3. The valve of claim 1, wherein the cap portion further includes a second aperture extending from the outer surface of the outer wall into the second circumferential groove.
4. The valve of claim 1, wherein one of the opposing ends of the plastic rod is hook shaped.
5. The valve of claim 1 , wherein the plastic rod is cylindrical.
9
6. A valve comprising: a first portion including a cylindrical wall structure having an outer surface defining a first circumferential groove therein, the first circumferential groove presenting a back wall with a recess defined therein; a second portion having a cylindrical outer wall and an inner wall spaced apart and concentric with the outer wall, the outer wall and inner wall defining a recess therebetween for receiving the cylindrical wall structure of the first portion, the outer wall defining a second circumferential groove facing into the recess and at least one aperture extending from an outer surface of the outer wall into the second circumferential groove; and an elongate plastic rod presenting a pair of opposing ends, wherein the first portion of the valve is selectively operably couplable to the second portion of the valve by first engaging the cylindrical wall structure of the second portion in the recess of the first portion with the first and second circumferential grooves in registry and the recess of the first portion registered with the at least one aperture in the second portion, inserting one of the opposing ends of the plastic rod through the at least one aperture into the recess of the first portion, and rotating the second portion to draw the plastic rod into the first and second circumferential grooves whereby the plastic rod extends circumferentially around the first portion and circumferentially within the inner wall of second portion engaged in the respective circumferential grooves securing the first and second portions together.
7. The valve of claim 6, wherein the aperture in the second portion is oblong.
8. The valve of claim 6, wherein the second portion further includes a second aperture extending from the outer surface of the outer wall into the second circumferential groove.
9. The valve of claim 6, wherein one of the opposing ends of the plastic rod is hook shaped.
10. The valve of claim 6, wherein the plastic rod is cylindrical.
11. A method of coupling valve components comprising:
10 forming a first component including a cylindrical wall structure having an outer surface defining a first circumferential groove therein, the first circumferential groove presenting a back wall with a recess defined therein; forming a second component having a cylindrical outer wall and an inner wall spaced apart and concentric with the outer wall, the outer wall and inner wall defining a recess therebetween for receiving the cylindrical wall structure of the first component, the outer wall defining a second circumferential groove facing into the recess and a first aperture extending from an outer surface of the outer wall into the second circumferential groove; providing an elongate plastic rod presenting a pair of opposing ends; and coupling the first component to the second component by first engaging the cylindrical wall structure of the second component in the recess of the first component with the first and second circumferential grooves in registry and the recess of the first component registered with the first aperture in the second component, inserting one of the opposing ends of the plastic rod through the first aperture into the recess of the first component, and rotating the second component to draw the plastic rod into the first and second circumferential grooves whereby the plastic rod extends circumferentially substantially around the first component and circumferentially within the second component thereby securing the first and second component together.
12. The method of claim 11, wherein the component has a second aperture extending from an outer surface of the outer wall into the second circumferential groove, and wherein the method includes rotating the second component until the other of the opposing ends of the plastic rod is engaged in the second aperture.
