Pressure Vessel System and Method

摘要

Diaphragm joint and convolutions, bottom screen diffuser, air stern, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel.

主权项

1. A joint system for a pressure vessel, comprising:
a first tank liner having a first circumferential side wall and a first end portion offset from the first circumferential side wall to form a first outer annular recess; a second tank liner having a second circumferential side wall and a second end portion offset from the second circumferential side wall to form a second outer annular recess; an H-ring having a first circumferential groove and a second circumferential groove, the first circumferential groove configured to receive the first end portion of the first tank liner and the second circumferential groove configured to receive the second end portion of the second tank liner; and fiberglass windings surrounding the first tank liner and the second tank liner in tension and configured to lock the first tank liner and the second tank liner together.
