Pneumatic ball valve is a ball valve with pneumatic actuator. It is a kind of automatic equipment that drives the ball valve to open and close by the compressed air, complete the switching and conditioning of the medium, and then reach the switching or conditioning intention of the pipeline medium. Pneumatic ball valves are generally equipped with various accessories, such as solenoid valves, air source treatment triples, limit switches, positioners, control boxes, etc., to complete local control and remote centralized control. The valve can be switched on and off in the control room. There is no need to go to the scene or high altitude and bring manual control at risk, which greatly saves manpower and safety. There are different types of pneumatic ball valves, including stainless steel pneumatic ball valve, plastic pneumatic ball valve, sanitary pneumatic ball valve, carbon steel pneumatic ball valve, 2 way pneumatic ball valve, 3 way pneumatic ball valve, etc.

Cover the grill's lid if necessary: Hot dogs, hamburgers and other food intended for fast cooking can be grilled without a lid. If you have any food for slow cooking, such as boned chicken or loin chops, just cover the lid on the grill. In doing so, indirect heat is increased to help cook food thoroughly. If you need to cook food for a long time, you should add new charcoal every 30 or 60 minutes. Don't lift the cover frequently to check your food because it will lead to heat loss.

The steel tape measure is measured in centimeters. The red “10” means 10 centimeters, and the cells in centimeters mean millimeters. Steel tapes can be divided into self-rolling tapes, braking tapes, and rolling tapes. The numbers on the metal tape measure are divided into two rows, the unit of one row is cm, and the unit of the other row is inches. 1cm≈0.3937 inches, 1 inch≈2.54cm. Therefore, when the difference between the two numbers is small, the unit uses centimeters, and when the difference is large, the unit uses inches. The font of numbers in centimeters is also smaller than that of inches.

What’s the rotary laser level working principle? The working principle of laser level is to use the monochromaticity and coherence of laser. A glass or metal sheet with a certain shading pattern can be assembled in front of the telescope objective lens, that is, the zone plate, so that the diffraction interference generated by it can be made. After focusing by the telescope, within the focusing range of the zone plate, a bright and fine cross-shaped or circular laser spot can be obtained, so that the target can be aimed more accurately. If the front and rear leveling rulers are equipped with photoelectric receiving targets that can be tracked automatically, leveling can be performed. In the construction survey and the assembly of large components, a laser level is often used to establish a level surface or a level line.

The operating principle of plant growth lights is as follows: The light provides a light spectrum similar to that of sunshine or is suitable for cultivating plants. The light sends different colors and changes its lumen output (intensity) to simulate the varied temperatures and spectrum output of the outdoor condition. As the category of cultivated plants, cultivation stage (such as germination/vegetative stage or florescence stage/fruiting period) and the light cycles needed by plants vary, the spectrum stage, lighting efficiency, and color temperatures should be adjusted flexibly.

To clean the grill with greater ease, you should mix vinegar, lemon juice, and a sauce containing soy sauce for marination and sprinkling. Next, place all cleaning tools near the barbeque tool so that they can be used more conveniently and faster. Meanwhile, it also helps to develop the habit of cleaning the grill after using it. You'd better smear the barbeque sauce with ketchup a few minutes before food is taken out of the oven to reduce the workload of scrubbing. Prepare a piece of tin foil if you have no brush suitable for cleaning the grill. Firstly, fold the tin foil paper into a ball with a 3cm diameter, clamp the grill with a food clip, and scrub it bit by bit. Next, scrub another metal strip after cleaning one. The grill should be cleaned thoroughly at least once a year.

Screwdrivers are common hardware tools, among which pneumatic screwdrivers are one of them. It is used to tighten and loosen screws and nuts. The shells of Pneumatic screwdriver are mostly made of metal, which feels slightly worse than electric ones. But the metal shell has better anti-static performance and is very labor-saving and convenient to use.

The electronic lawnmower is a mechanical tool for trimming the lawn and vegetation, and its advent has brought great convenience. It is composed of a cutter, an engine, a road wheel, blades, two handrails, and a control part. The cutter is installed on the road wheel and driven by the engine. Some blades are installed on the output axis of the engine, which is driven by the engine and rotates at a high velocity. It not only saves operating time for lawn workers but also reduces plenty of human resources.

Ultrasonic thickness gauge working principle Ultrasonic thickness gauge mainly adopts the principle of ultrasonic pulse reflection method to measure the thickness of materials and objects conveniently and quickly, so as to realize the most basic thickness measurement function. Ultrasonic thickness gauge applications Ultrasonic thickness gauge is mainly used to detect hard materials (steel plates, glass, etc.). However, soft materials (such as sofas, sponges, etc.) cannot be measured with an ut thickness gauge. In addition, when testing the thickness of the material, attention should be paid to the sound velocity of the material being measured. The sound velocity of different materials is different.

Electric pruning shears are among the electric tools commonly used to trim and cut branches and leaves in orchids, gardens, mulberry trees, and vine grapes. Compared with traditional manual scissors, electric pruning shears are characterized by high efficiency, resistance, trimming quality, and security protection performances. However, professionals should receive training before operating electric pruning shears and attach importance to specific methods. After being used, electric pruning shears should be cleaned in time, stored in a safe place, and maintained regularly.

Laser distance meters measure distances by taking lasers as the light source and can be roughly divided into CW laser distance meters and pulsed laser distance meters. Laser distance meters applying gases, including helium-neon, argon ions, and krypton cadmium, work with continuous output and are used for phase-shift laser ranging. Semi-conducting laser distance meters made of DH gallium arsenide are used for infrared distance ranging, while solid laser distance meters made of rubies and neodymium glass are used for pulsed laser ranging.

Compared with ordinary electric drills, firstly the electric screwdriver adds the "setting torque" function, that is, it will jump out if the torque exceeds a certain torque, so it will not blindly twist the screw hole. Secondly it adds the forward and reverse gears to loosen and tighten the screw. Besides, it has added with the low speed gear to be more suitable for screwing. If the torque is too small, the screw can't be twisted, and if the torque is too large, it is easy to damage the product and cause serious slippage. Therefore, it is best to buy an electric screwdriver with precise torque settings with appropriate maximum torque, and multiple gear adjustments.

The laser distance meter is a measuring tool that accurately determines the distance of the target using a certain parameter of the modulated laser. The pulsed laser distance finder will emit a beam or a sequence of short pulsed laser beams to the target when it is working and receive the laser beam reflected by the target. Then the time from the launch to the reception of the laser beam will be measured by the timer, and the distance between the laser distance measure and the target will be calculated. When the power of the emitted laser beam is sufficient, the range of the laser distance meter can reach about 40 kilometers or more. It can operate day and night, but the distance and accuracy of the ranging will decrease when there are substances with high laser absorption rate in the space.
