Air / Water Channel Assembly
A manufactured device, prefabricated assembly or on-the-job assembly of component parts that is an adjunct to the basic piping system and plumbing fixtures.
The appurtenance requires no additional water supply and does not add any discharge load to a fixture or to the drainage system.
The valve assembly 100 may be disposed at an end of a pipe line in a wet piping system for the purposes of flushing or purging residual air (or other gas) from the pipe system. The strainer 102 may be positioned directly adjacent (e.g., in the direction of fluid flow) to the integrated ball valve 101. Attached to the strainer 102 is an angled port 105.
Air / Water Valve
The Air / Water Valve is used in the irrigation systems to get rid of trapped air, which helps to prevent pipe bursts and head losses. Besides, it also reduces energy consumption and corrosion rates. The air release valve can be fitted on the surface or on a separate vault to vent the gases and ensure the proper functioning of the pipelines.
A combination air valve is designed to have both an air release function and an air & vacuum function. The air release component releases small pockets of air that accumulate along a piping system when it is full and operating under pressure, and the air & vacuum component discharges or admits large volumes of air during the filling or draining process.
The D-060 NS series Combination Air Valve may include an air vent assembly 200 that includes a tubular member with an inlet and an outlet. The tubular member is connected to an angled port 204 via an Air / Water Channel Assembly elbow 207 or by a pipe nipple 208, whichever is more appropriate.
Attached to the angled port is a strainer 102 that is designed to prevent particulate matter from flowing into an attached air release valve and from impacting the integrity of the air release valve. The angled port also enables the valve to be properly oriented without having to use additional fittings or connectors, thus reducing cost and minimizing installation time.
Another feature of the angled port is that it may be formed at an angle, such as a right-angle, to facilitate proper orientation of an attached air release valve without compromising its performance or lifespan. In addition, the angled port may be positioned to allow for the separation of air from the incoming air before it reaches the valve.
This is beneficial for the insertion of the air valve because it minimizes the potential to generate water hammer under column separation conditions or excessive high fill rates. It also eliminates the need for a manual float or pump operation to release the air that is accumulated in the high spots of the pipe, which can be a major drawback.
Luer Lock
A Luer Lock is a small bore friction based fitting with interlocking threads forming the nucleus of a family of very functional and very useful connectors. They can be configured to work with a wide array of materials and are commonly used in the medical industry for gas chromatography, cell research, intravenous catheters, feeding tubes, ventilators and the ubiquitous hypodermic syringe.
The luer lock is most commonly found on the front end of the syringe where it allows for a more fluid and comfortable connection between the needle and syringe. It also prevents the dreaded needle slippage which in turn reduces the chance of broken needle tips or worse a bleed.
There is more to a luer lock than meets the eye but you need to be a bit of a medical professional to appreciate the details. In short, the luer lock is the most effective way to connect tubing and ancillary devices in a safe and controlled manner. The luer lock may not be the best solution for every application, but it does work well on the most common.
PTFE Tubing
PTFE (polytetrafluoroethylene) tubing, or Teflon(r) tubing, is the most flexible of fluoropolymers and has one of the widest operating temperature ranges. It can resist a number of harsh chemicals and acids without degrading, and is non-permeable, meaning water cannot penetrate it.
Typical applications for PTFE tubing include chemical process, high Air / Water Channel Assembly and low temperature, brushing and bearing, electrical, automotive and laboratory equipment. This material is a great choice for these industries, as it offers a smooth surface finish and a low coefficient of friction and lubricity.
It’s also used for filtration, as its surface is very smooth and makes it easy to transfer fluids. PTFE tubing is especially useful for antibacterial applications where bacterial buildup can be a major problem, so a smooth ID and OD are important.
Another benefit of PTFE tubing is that it has excellent dielectric properties. This means that it will effectively insulate electricity from the incoming and outgoing lines, as well as from other components. It also has a low coefficient of friction, making it ideal for delicate processes and equipment.
Aside from its low coefficient of friction, PTFE tubing is also resistant to corrosion. This makes it the perfect choice for transporting chemicals, even in corrosive environments.
There are many different types of PTFE tubing, including multi-lumen tubes. These have multiple layers of tubes inside a single tube, each of which contains a different type of fluid or wire.
These are often used in medical applications where radioactive materials can be added to a tube. They can also be filled with a substance to give the tube X-ray or radioactive properties, or they can be made heat shrinkable.
Typically, PTFE tubing is manufactured with tight tolerances to ensure that it is leak free. This is essential for many industrial applications, as leaks can cause expensive damage and loss of production.
PTFE tubing is available in a variety of lengths and sizes, from 3mm to 30mm. It is made from a high-quality PTFE resin, and it can handle a variety of liquids and gases. It can also be flanged or flared, as needed.
