Irrigation System Backflow Prevention Devices Backflow prevention system attachments include Y-type strainers and Aqualine hose-end vacuum breakers. Y-type strainers are filters which protect backflow devices by filtering sediment from the system. Hose-end vacuum breakers attach to the end of your garden hose to prevent water which has passed through it from re-entering the system.

Backflow Prevention and Cross-Connection Control Reduced Pressure Principal (RPP) backflow prevention device installed to EVMWD standards. There are other types of devices to protect the water distribution system or on-site potable system. The type of device to be installed to protect the potable water system is determined based on water use and backflow potential. Types of backflow prevention devices are listed below:

DuocelÂ® Foam Energy Absorption While the first half of the foam stress / strain curve is the section generally used in the design of any foam energy absorber, the second half, or safety back-up zone section represents a special energy absorption reserve. When designing energy absorbers, you have to proceed with the best data available.

- The strainer shall have a cast iron housing and a stainless steel basket, removable from the top of the housing. Solids shall be flushed into the discharge line during the discharge cycle. A control valve shall prevent back-up into the house line during discharge cycles and permit cut-off of either pump.

Relief Headers It is often desirable to combine the discharges from safety relief valves into common pipe headers. The common headers are piped to a safe location, with provision for collecting liquid relief and treating vapor discharge. VentManifold is an Excel spreadsheet template that calculates the backpressure that develops when simultaneous vents discharge into a common header. This is important because relief valves are designed to operate within specified back pressure limits. This page discusses the design of relief valve discharge manifolds. A relief valve discharge header takes the form of a tree. Each valve, vent, or rupture disc is piped to a branch; branches may combine into larger branches. Finally, the main trunk is reached, discharging to atmosphere (perhaps by way of a large knock-out drum or scrubber).

What are the Differences Between Mustang H, X & Y Pipes? The poor lowly Y-pipe. The stock factory Y-pipe found on V6 Mustangs serves its purpose very well to exit the engines exhaust to the rear of the car and that’s about it. The Y-pipe’s restrictive design does not flow very well (compared to an X or H) and does not add any real performance benefits to your vehicle.

- Training In the Purpose, Use and Care of In-line Liquid Strainers Purpose of Equipment In-line liquid strainers are used to trap and remove solid items from the liquid stream. Typically a screen or fine mesh catches the solid while letting the liquid through. A strainer is used to trap larger items than a filter, which is used to catch extremely small materials and fibres. Figure 1 In-line Strainer In-line Strainer Y-Strainer Twin Basket Strainer Pictured in Figure 1 are several types of in-line liquid strainers. The twin, or duplex, basket strainer allows one side to be cleaned out while the other is in service. The numbered items on the twin basket strainer are: 1. Quick release bolts to remove the screen. 2. Inlet nozzle for the liquid. 3. Internal valve sealing system between

Washing Machine Drain Hose Backflow Prevention Drain Hose. The washing machine drain hose must be maintained if backflow and other drainage issues are to be avoided. Keep the drain hose free from kinks and knots, and minimize the number of twists and turns in the hose between the washing machine and the standpipe.Be careful not to crush the hose when you slide your washing machine back in against the wall.he drain vent is a piece of metal pipe that prevents vents to the outside, allowing air into the plumbing system to prevent vacuums from forming as water is discharged down the drain. This keeps the drain moving freely, and prevents slow draining issues that can cause overflows.

Entrainment Separators The open flow design keeps pressure loss low. Our other Inline Design is a straight thru that uses a helical baffle to create the centrifugal separation. The body of the separator follows the line requiring less space for installation. These separators are available in horizontal, upflow, or downflow models. All Penn Inline Entrainment Separators are designed and stamped ASME code in threaded, 150# flanged or 300# flanged. Special pressures are also available.

Yamaha Technology 1980: YPVS (Yamaha Power Valve System) The YPVS employs a spiral shaped valve located on the top of the cylinder’s exhaust port. This valve is operated by means of a cable from a computerized mechanical control unit which detects the ignition frequency and determines the required turning angle of the valve. In this way the valve moves upward and downward out of the exhaust port.

What is the difference between yield point and elastic limit? Stress Strain Curve Explanation. Stress strain curve is the plot of stress and strain of a material or metal on the graph. In this the stress is plotted on y axis and its corresponding strain on the x axis. After plotting the stress and its corresponding strain on the graph, we get a curve, and this curve is called stress strain curve or stress strain diagram.
