Abstract

In one example, a fluid system component includes a first element and a second element, where one or both of the first and second elements are configured to be exposed to a fluid. The fluid system also includes a flexible diaphragm positioned between the first and second elements. Finally, the fluid system component includes one or more retaining elements, each retaining element having a first portion received in the first element and a second portion received in the second element. The retaining elements also extend through the flexible diaphragm.

Claims

1. A fluid system component, comprising:

a first element;

a second element, wherein one or both of the first and second elements are configured to be exposed to a fluid;

a flexible diaphragm positioned between the first and second elements; and

a plurality of retaining elements, each retaining element having a first portion received in the first element and a second portion received in the second element, and the retaining elements each extending through the flexible diaphragm.

2. The fluid system component as recited in claim 1, wherein each of the retaining elements comprises a pin.

3. The fluid system component as recited in claim 1, wherein the first and second elements each comprise respective first and second complementary that are engaged with each other, and wherein a portion of the flexible diaphragm is held between the first and second complementary structures.

4. The fluid system component as recited in claim 1, wherein the fluid system component comprises a valve.

5. The fluid system component as recited in claim 1, wherein the fluid system component comprises a pump.

6. The fluid system component as recited in claim 5, wherein the first element comprises a pump head, and the second element comprises a pump body.

7. The fluid system component as recited in claim 1, wherein one or more of the first element, second element, retaining elements, and diaphragm is substantially constructed of plastic.

8. A fluid pump, comprising:

a pump body;

a pump head attached to the pump body;

a flexible diaphragm positioned between the pump head and pump body; and

a plurality of retaining elements, each retaining element having a first portion received in the first element and a second portion received in the second element, and the retaining elements each extending through the flexible diaphragm.

9. The fluid pump as recited in claim 8, wherein the pump body, pump head, and the flexible diaphragm are substantially constructed of plastic.

10. The fluid pump as recited in claim 8, wherein the pump head and pump body each comprise respective first and second complementary structures that are engaged with each other, and wherein a portion of the flexible diaphragm is held between the first and second complementary structures.

11. The fluid pump as recited in claim 8, wherein one or more of the retaining elements is located outside of a pump seal cooperatively formed by the first and second complementary structures and the flexible diaphragm.

12. The fluid pump as recited in claim 8, wherein one or more of the retaining elements is located within a pump seal cooperatively formed by the first and second complementary structures and the flexible diaphragm.

13. The fluid pump as recited in claim 8, wherein one or more of the retaining elements is implemented as a pin, each pin having a first portion received in a recess defined by the pump head, and the pin having a second portion received in a recess defined by the pump body.

14. A fluid pump, comprising:

a pump body that defines a first complementary structure;

a pump head attached to the pump body, the pump body defining a second complementary structure configured to engage the first complementary structure;

a flexible diaphragm positioned between the pump head and pump body, a portion of the flexible diaphragm being positioned between the first and second complementary structures; and

a plurality of retaining elements, each retaining element having a first portion received in the first element and a second portion received in the second element, and the retaining elements each extending through the flexible diaphragm.

15. The fluid pump as recited in claim 14, wherein the first complementary structure comprises a circumferential groove with a substantially V-shaped cross-section, and the second complementary structure comprises a circumferential ridge having a substantially V-shaped cross-section.

16. The fluid pump as recited in claim 14, wherein the pump body a threaded pump head mount, and the fluid pump further comprises a union configured to engage threads of the pump head mount and releasably retain the pump body, flexible diaphragm and pump head together.

17. The fluid pump as recited in claim 14, wherein the retaining element each comprise a pin that is located outside of a pump seal cooperatively formed by the first and second complementary structures and the flexible diaphragm, the pins being disposed about a circumference of the flexible diaphragm.

18. The fluid pump as recited in claim 14, wherein the pump head, pump body, flexible diaphragm and retaining elements are substantially constructed of plastic.

19. The fluid pump as recited in claim 14, wherein the pump body comprises an additional pump head mount, and the fluid pump comprises an additional pump head mounted to the additional pump head mount.

20. The fluid pump as recited in claim 14, wherein the fluid pump is operable to pump a process fluid in response to receipt of a flow of a pressurized operating fluid.

21. The fluid pump as recited in claim 14, wherein the flexible diaphragm comprises one of the following types of diaphragms:

flat;

blousing;

pillow;

trampoline;

convolute;

shallow draw;

dish;

“

pie pan;

”

drop center;

offset convolute;

deep draw;
