Disclosed is a water piping system. More particularly, the present invention relates to a water piping system having a function to dampen the effects of water hammer and check valve slam at a sudden stoppage of a pump and relates to a tank connector therefor, in which the water piping system ejects a high pressure jet stream from a high pressure tank in the direction of a primary flow in a main pipeline, thereby deterring the backflow of pipeline water in the main pipeline and reducing the pressure of pipeline water against a check valve, which enables the check valve to be slowly closed.

A water hammer prevention system using an operation state analysis algorithm to prevents water hammer. Data is measured in real time by a pressure sensor and a water level sensor are transmitted to a control unit and stored in a database. The control unit includes an air chamber which controls the operations of an air compressor and an air exhauster to prevent water hammer. The control unit performs calculations according to a water hammer algorithm, and determines the operation states of the air compressor and the air exhauster, and whether the water hammer prevention equipment is operating normally. Active operational control of the water hammer prevention equipment can be performed by applying a data analysis technique thereto, and a failure or operation error can be identified.

The present invention relates to a water piping system prevents degradation of water quality due to fluid remaining in a fuel tank for a long period of time and removes air and other impurities in a pressure tank and a pipe, and a method of controlling the same. The water piping system includes: a pump pressurizing fluid; a main pipe for delivering the fluid pressurized by the pump; a main valve disposed at an outlet port of the pump in the main pipe; a pressure tank connected to the main pipe; and a sub-pipe having a first end connected to a front side of the main valve of the main pipe and a second end connected to the pressure tank so that some of fluid pressurized and discharged from the pump is delivered to the pressure tank through the sub-pipe, thereby discharging substances in the pressure tank to the outside.

Disclosed is an in-flow pulsation dampening system for high-pressure (e.g., 10K psi and higher) fluid lines. At high fluid flow pressures, the dampening system is a dual stage dampening system, responsive to low (e.g., when first charging the fluid line) and to very high-pressure pulsations. An external containment shell handles the full fluid flow pressures. One or more internal shells contain and handle the internal gas dampening system. The in-flow relationship of the gas dampening component assures that pressure differences between the internal gas handling system and the high-pressure fluid flow is always relatively small. This enables the gas handling components to be constructed of less robust material than the external shell (even though the gas system's internal pressure can equal that of the fluid flow), and be less susceptible to pressure failure.

Disclosed is a control system for a pulsation dampener device. The system comprises a fluid reservoir, a pipeline assembly extending between the reservoir and the bladder of the pulsation dampener device, and a bladder sensor for gauging the fluid pressure within the bladder. The system is configured such that, when the pulsation dampener device is not operative and when the pressure of the fluid within the bladder is above or below a predetermined preoperative bladder threshold, the excess or deficient equivalent volume of fluid respectively is transferred from the bladder to the reservoir or from the reservoir to the bladder respectively. Further, when the pulsation dampener device is operative and when at least one pressure reading of the fluid within the bladder is above or below a predetermined operative bladder threshold, the excess or deficient equivalent volume of fluid respectively is transferred from the bladder to the reservoir or from the reservoir to the bladder respectively.

An elastically deformable article of manufacture can comprise a closed polymer shell having an outer surface, an inner surface, and an inner volume; a reinforcement in mechanical communication with an area of either the outer surface, the inner surface, or both the outer surface and the inner surface; wherein the closed polymer shell comprises a first polymer material having a thermal decomposition temperature of greater than or equal to 180 C.; wherein the article is configured such that the inner volume reduces from an initial inner volume as a pressure applied to the outer surface is increased to a threshold pressure and rebounds to greater than 75% of the initial inner volume as the pressure decreases from the threshold pressure over at least two pressure cycles.
