If you live in high wind rated areas in South Florida like Miami you have to be prepared for hurricanes with impact windows Miami approved. There are many ways of protecting your home from high wind loads, however when it comes to Dade County, in order to get permitted to build any type of building, the windows and doors have to be wind rated. Dade County is one of the most challenging areas in America to build due to these hurricanes. Never the less impact windows has and will continue to save lives.
Hurricane force winds are no joke, once a door or a window breaks open the wind will blow the roof off the building, this is very common in hurricanes when the doors or windows are not up to date (wind rated). This will result in you and your family’s life being put in danger. Taking the time now to protect your home is a safe investment and more importantly a great way to protect your family and belongings from these life threatening weather conditions.
With the latest technology, wind rated windows and wind rated doors are exceeding Dade county requirements, Miami Dade has the highest County wind load requirements in the USA, getting your city’s permission to build is very important and in order to get permitted to build you will have to follow the wind regulations. Impact windows and impact doors are just part of the plan, in Dade County everything has to be wind rated.
Throughout the history of humankind, different types of buildings have been constructed depending on various factors such as the building materials available, the specific uses of the buildings, and the level of expertise of the builders. And, buildings have evolved from one decade to the other to reflect the needs of the society. Notably, steel buildings have earned the marvel of many during these modern times.
Generally, steel buildings refer to metal structures in which the members are made of steel in order to offer internal support as well as exterior cladding. The steel components of these buildings are generally joined by welding, riveting or bolting, and this reinforces their strength. The construction of steel buildings is usually accomplished through industrial processes. In modern construction, steel buildings are best known for the diversity of their shapes as well as their architectural expressiveness that make them more reliable than other types of structures. During this century, steel buildings have evolved into various specific types according to their use, which can be storage, places of work, living accommodation, and others.
Steel buildings offer several advantages. To begin with, due to the high strength of steel, the strength of these buildings is unmatched compared to structures constructed using other building materials. This is particularly essential when one desires to have a building with a strong foundation for use with heavy machinery. Next, steel buildings save time and money as compared to using conventional building systems. The inherent strength of steel implies that less structural members are required, and this translates to savings in construction, maintenance, and replacement costs. Other benefits of steel structures include increased sanitary conditions, environment conservation, and flexibility in case of alteration for different uses. On the hand, the main disadvantage of steel buildings is their susceptibility to corrosion. However, this can be surmounted easily through applying some protective measures, for example, applying special coatings and paints.
A butterfly valve otherwise known as quarter-turn valves, isolate and control the flow of a liquid. Most often used in water or waste treatment, especially in the field of agriculture, a ball valve , much like butterfly valves, also have the distinction of being one of the most common valve types on the market. Butterfly valves serve reliably even when a heavy-duty valve is required. These valves need very little maintenance and are extremely durable.
Butterfly valves are devices used for flow control, usually the flow of a fluid through a section of pipe. The butterfly valve operates similarly to an electric ball valve. A flat disc located at the pipe’s center has a rod running through it that connects to the actuator on the exterior of the valve. Turning the actuator rotates the plate to a position either perpendicular or parallel to the flow. The flow may be regulated more specifically through different disc rotations.
The “butterfly” is the metal disc mounted on the rod. When the valve is in the closed position, the disc is rotated to a position in which it totally blocks the passage of liquid. When the valve is open fully, the disc has been rotated one-quarter turn—90 degrees—allowing for nearly unrestricted passage. Flow may be incrementally regulated by various positions of the valve. This advantageous feature of butterfly valves makes them ideal for many industrial uses. The size of butterfly valves is one more of their advantages. Since they are lighter and smaller than other valve forms, they do not necessitate the large degree of supporting structure required for other valves, such as the electric ball valve.
The butterfly valve has a resilient seat, a body, a butterfly disk, packing, a stem, an actuator, and a notched positioning plate. When the resilient seat is mounted in the valve body, it is under compression and makes a seal around the edges of the disk and the lower and upper points where the stem runs through the seat. Packing provides a positive seal all around the stem for extra protection, should the seal made by the seat suffer damage.
Butterfly valves are available in different styles, such as high-performance and eccentric valves. Butterfly valves can be found on fire apparatus and large lines, such as tank to pump lines and rear and front suctions.
The design of the butterfly valve does give it a disadvantage, because unlike an electric ball valve, a portion of the disc will always be in contact with the liquid, regardless of whether it is in the open or closed position, and this causes a constant pressure switch regardless of the setting. Viscous or thick liquids also may slow the disc’s functional movement.
Though butterfly valves may be configured for electronic or manual operation, the most rapid is pneumatic control. The gearbox must receive a signal to both open and close an electric ball valve. However, an advantage to pneumatic operation lies in its flexibility, for it permits either double or single actuation. Single actuation requires a fail-safe, so that in the event of power loss, on a spring-loaded system, the valve will change to the closed position if open. So, a signal must be sent to open the valve initially. Double actuation valves need signals to both open and close the mechanism, because they are not spring-loaded.
