Solenoid valve is used to control the fluid of the basic components of automation, are actuators; is not limited to hydraulic, pneumatic. Solenoid valve used to control the direction of hydraulic flow, the factory's mechanical devices are generally controlled by the hydraulic cylinder, it will use the solenoid valve. Working principle Solenoid valve has a closed cavity, opened in different locations through-hole, each hole leads to different tubing, the middle of the valve is the valve, on both sides of the two electromagnets, which side of the magnet coil body will be energized Is attracted to the side by moving the valve body to stop or leak different drain hole, and the inlet hole is normally open, the hydraulic oil will enter the different oil pipes, and then through the pressure of oil to promote Oil just piston, the piston and piston rod, piston rod driven mechanical device. This controls the mechanical movement by controlling the electromagnet current. Category 1. Solenoid valve from the principle is divided into three categories: 1) Direct Solenoid Valve: Principle: When energized, the electromagnetic coil electromagnetic force to produce the closure from the valve seat lift, the valve opens; power, the electromagnetic force Disappears, the spring pressure to close the valve seat, the valve closed. Features: In vacuum, negative pressure, zero pressure can work normally, but the path generally does not exceed 25mm. 2) Distribution of direct-acting solenoid valve: Principle: It is a direct acting and pilot-based combination of principles, when the inlet and outlet without pressure, the power, the electromagnetic force directly to the pilot valve and the main valve closing member in turn Lift up and the valve opens. When the inlet and outlet to achieve the start of the pressure difference, the electricity, the solenoid pilot small valve, the main valve lower chamber pressure rises, the pressure on the chamber down, so that the use of pressure to push the main valve open; power, the pilot valve spring Force or media pressure to push the closure, move down, the valve closed. Features: At zero pressure or vacuum, high pressure can also be * action, but the power is larger, the requirement must be horizontal installation. 3) Pilot solenoid valve: Principle: When the power is on, the electromagnetic force opens the pilot hole and the pressure in the upper chamber rapidly drops. The low and high pressure difference is formed around the closing member. The fluid pressure pushes the closing member to move upward and the valve opens. Electricity, the spring force to close the pilot hole, the inlet pressure through the bypass hole quickly chamber around the valve to form a low pressure on the next high, fluid pressure to promote closure of the move down to close the valve. Features: High fluid pressure range high, can be installed (to be customized), but must meet the fluid pressure conditions. 2. Solenoid valve from the valve structure and material differences between the principle and the difference is divided into six sub-categories: direct acting diaphragm structure, step-by-step re-structure, the first film structure, direct acting piston structure, step Direct acting piston structure, the pilot piston structure.
LED Plant Grow Light
Products Description
LED Grow Light is the newest trend for indoor growers. Advanced LED Grow Lights use less energy,and create less heat,not only provides intense, effective lighting for indoor gardening but also make the garden cool. Hydroponics,which is a method in high-tech horticulture where plants grow in soil-free nutrient baths,led hydroponic lamp is a perfect example of how science and technology can work together to develop solutions to human problems.
Advantages for led grow light
1. Bring You High Yield
The traditional grow lights, such as HID and HPS can just bring you 0.5 -0.8 gram per watt, no more than 1 gram. But the led grow light can bring you 1-2.5 gram per watt. It's amazing! LEDs in greenhouses deliver same yield as grow lights, using just 25% of the energy. So as for the energy conservation and environmental protection light source, the planters will consider the led grow light as their first choice.
2. Less Heat
While most grow lights are very warm, as HID, so you would need use the fan to solve this problem in summer. LED grow lights are generally moderate in temperature, and they will not harm a person if he touches them. As such, it is much safer and convenient for owners and their crops, they can be placed very close to the plants to deliver high intensity lights to the surface of the leaves.
3. Low Cost On Everything
Less electricity, save about 60% than HID.
Low amounts of heat, means less money spent on the room's costs of cooling.
Long life-span, no need to replace the bulbs.
No ballast.
No reflector.
