definition:
The guardrail lamp is a road lamp installed in a road guardrail. Usually, a fluorescent tube or an LED is used as a light source, and a continuous guardrail is used as a carrier to form a linear or approximately linear guardrail strip.
use:
The traditional guardrail lamp mainly uses plastic pipe as the guardrail material, which is simply used as the night landscape light belt, and the illumination of the road surface is carried by the pole lighting (street light pole). The new generation of guardrail lights use steel pipes as guardrail materials, which are waterproof, dustproof and anti-collision. Lamps can be used as an alternative to streetlights for lighting on the road surface, as well as a simple landscape light strip, or both, to achieve a combination of road lighting, collision avoidance and landscape.
Features:
It can be placed on the PCB board in a straight line in the order of red, green and blue. It is controlled by a dedicated driver chip to form endless colors and graphics. The shell is made of flame-retardant PC plastic, high strength, impact resistance, anti-aging, anti-UV, dustproof, moisture-proof, protection grade IP65.
Application range:
The guardrail light is especially suitable for use in billboards, overpasses, rivers, lake guardrails, building contours and other large moving photoreceptors, which can produce rainbow-like effects. Decorate the outline of the building with a guardrail tube to highlight the effect of beautifully colored buildings. It turns out that it has become a wonderful thing in lighting products, blooming in a dynamic city.
There are five general body styles of ball Valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is the same in each case.
In addition, there are different styles related to the bore of the ball mechanism itself.
Ball valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
