With the continuous advancement of modern science, people’s material life is gradually becoming more abundant, and the demand for quality of life has become higher. As food safety accidents continue to occur, people's demand for green, pollution-free foods continues to increase, and green, pollution-free foods become hot products in the market. The best natural environment can produce green pollution-free crops, and to achieve this, we must first reduce the impact of pesticides on crops.
Many regions blindly use pesticides to kill insects in the season of pests, which not only makes the agricultural ecological environment highly toxic, but also brings about pesticide residues in vegetables, fruits, and soil water sources, thus endangering people's health and safety. The insect observation lamp utilizes the spectral frequency conversion technology to break through the limitations of the use of a single optical band for the traditional insecticidal lamp, which enables a wider range of effective light waves and more types and numbers of insect pests to be killed and killed. Night pests are attracted by the special lights and wavelengths of the insect observation lights, and they will pounce on themselves. At the periphery of the light, there is a high-voltage network of 3,000 to 5,000 volts. The pests will fly to the lights. During the process, electrocution was killed and a good insecticidal effect was achieved. The application of this product can reduce the use of pesticides and ensure the quality of fruits and vegetables.
The pest observation lamp is the primary tool for grassroots plant protection agencies to observe the dynamics of crop pests. For a long time, black light lamps have been used in the monitoring of pest lamp attraction in China. Such lamps need to be turned on and off by the staff every day. They are extremely inconvenient to use. In order to reduce the work intensity of pest detection and reporting personnel and promote the scientific and technological progress of monitoring work, the Zhejiang Insect Situation Observation Light achieves the automation of pest light monitoring on the basis of realizing convergence with historical data for forecasting, and is a high-tech high-tech domestic product.
The pest observation lamp products are widely used in various types of orchards, vegetable bases, tea plants, organic rice, sugar cane, tobacco, peanuts, cotton, flowers, such as agriculture, vineyards, citrus gardens, Yangmeiyuan, litchi gardens, apple orchards, and mango gardens. Forests, forest farms, green towns, parks and other places that need to be disinfested are pest killers. The pest observation lamp provides a reliable scientific and technological guarantee for the production of pollution-free and high-quality agricultural products for a large number of crop planting bases as well as obtaining organic certification and the development of tourism ecological agriculture. It is a high-tech and pollution-free physical pest control equipment.
Studies have shown that the insect observation lamp has the advantages of high automation, no environmental pollution, many types of insecticides, and good insecticidal effect. The pest observation lamp realizes the application of modern automatic technology, can switch light and insect body far-infrared treatment, and automatically switch the insect bag, specially set eight-bit automatic conversion system, the insect body is stored according to the day, and the whole lamp automatically runs.
After the live insect hits the screen, it is processed twice in the far infrared of the insect observation lamp. Compared with the routine use of poison bottles (potassium cyanide, etc.), the treatment process is completely harmless and avoids the traditional measurement and reporting tools. Use of highly toxic pesticides to the health hazards of the meteorologists. Because the pest observation lamp utilizes the characteristics of strong light-induced and wave-like characteristics of pests, the wavelength and frequency of the light are set within a specific range, and light and long-distance waves are used at short distances to attract insects to the insect pests. Observing the lights thus electrocuted, has achieved the purpose of killing insects.

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.
