1. Daylight: After direct sunlight, ultraviolet rays will cause cracks on the surface of the floor. Use curtains or blinds to block and avoid direct sunlight.
2. Rain: The wooden floor is inherently water-repellent. If it rains, the surface of the floor will be discolored, cracked and so on. Be careful to prevent rain.
3, oil pollution: after the floor oil stains, if not treated in time, will produce oil stains and discoloration. Wipe clean with a detergent, water, etc., and then wax.
4, chair: in order to minimize depressions and scratches, to maintain the beauty of the floor for a long time, it is recommended to put a cushion on the chair foot or put a foot pad under the chair.
5. Heavy objects: Under the heavy objects such as piano and refrigerator, it is necessary to lay the mat to protect the floor and prevent the partial load from being too large, resulting in floor depression and scratching.
6, air conditioning, humidifier: long-term use of air conditioning, indoor air will become abnormally dry, the floor is prone to expansion and contraction, which in turn causes the floor to create gaps and sound.
7. Fan-type heater: If the floor is blown to hot air for a long time, the surface coating will crack and the floor will shrink to create a gap. Pads should be placed on the floor for protection.
8. Water accumulation: If the surface area of ​​the floor is water, if it is not treated in time, it will cause discoloration of the floor, water stains and cracks. Wipe in time to keep dry.
9. White turbidity: After the water drops to the floor, the surface of the floor will turn white. This is because the durability of the floor wax is not good, the floor wax is peeled off from the floor surface, and a diffuse reflection phenomenon occurs.
10. Detergent: Never use alkaline cleaner. The ingredients in the wood react chemically with alkaline materials, causing the floor to become smeared or stained. Wipe with a wrung rag after using the cleaner.
11. Pets: Pet excrement can cause alkaline corrosion of wood, causing discoloration and stains on the floor.
12. Pharmacy: If the floor is stained with chemicals, it should be wiped with detergent/water. After wiping, the surface gloss of the floor will be reduced, and the wax should be repaired in time.
13. Ventilation: The newly renovated house will emit formaldehyde from the decoration materials and furniture, irritate the eyes or produce odor, and pay attention to ventilation and ventilation. It should be noted that the water droplets after condensation should not drip onto the floor.
14, floor wax: to choose the appropriate floor wax. Before waxing, first in the corner of the room or other unobtrusive places, a small area trial on the floor, confirm that there is no problem, then start full waxing.
Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.
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.
