Teach you how to choose kitchen fixtures
The lighting of the kitchen needs to be divided into two levels: one is the lighting of the entire kitchen, and the other is the lighting of washing, preparation, and operation. In general, the open kitchen cabinets, whether shaped, L-shaped or U-shaped cabinets, the use of light sources in the form of ceiling-embedded spotlights, the number of 6 to 10 ranging. Try not to use a ceiling light because it does not collect light and only has astigmatism, so it should not be installed in the kitchen. The light source chooses warm light as much as possible, so the light is very beautiful. The lightness of the kitchen should be moderate, and it is better to use fluorescent lamps that can maintain the original color of vegetables and fruits. This not only enables the dishes to exert their appetite for color, but also helps the housewife to have a higher discrimination when washing. Lamps are functionally based, generous, and easy to clean. Luminaire materials should not be rusted or have a good surface protective layer. The direction of the light should be projected from the front as far as possible so as not to cause shadows to hinder the work, especially when selecting the spotlight as a lighting fixture. It's best to put a light above the kitchen sink or the chopping case, otherwise things will be backlit at night, and poor vision is even worse at night. In some glass storage cabinets can be installed projection lamps, especially when the interior storage of some colored tableware, can achieve a good decorative effect. In terms of environment, don't use dark colors in kitchen ceilings. Don't use dim lights. Dark background with matte lights, kitchen lighting will be similar to the virtual. All in all, the kitchen is a place to cook, try not to dress it up too fancy, it is better to choose the own cabinet with light. Considering energy conservation, do not install too many lights and install smart switches.

People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
