Zhongzhao Lighting Engineering Design Award (outdoor/park, square) Project Name: Jingzhou City Center Night Scene Lighting Project (Ancient City Wall Section) Reporting unit: Shenzhen Jinguang Lighting Industry Co., Ltd. Jingzhou City, also known as Gangneung City, is one of the first historical and cultural cities in China. During the Spring and Autumn Period and the Warring States Period, Chu State built the capital for 411 years, which is the birthplace of Chu culture. Jingzhou is also the place where the three countries cultured and prospered. The story of "Guan Yu’s loss of Jingzhou" happened here. Jingzhou downtown night lighting project (the ancient city wall section) has been highly valued by the Jingzhou government and the enthusiasm of the Jingzhou people. Li Jianming, deputy secretary of the Jingzhou Municipal Party Committee and mayor, visited the construction site several times to inspect and guide the work. The Jingzhou Evening News, Jianghan Business Daily, Jingzhou TV Station and Jingzhou News Network continued to follow up on the construction progress and lighting effects. The construction situation was reported on several occasions and the construction workers were interviewed. The theme of the project is “Moon Run, Dream Jingzhouâ€, which uses light to show the thick feeling of the ancient city wall and extend the historical context. The color of the ancient city wall lighting is based on the light color of white, warm white and so on. The color of the ancient city wall is dyed with jade, and the condensate and vicissitudes of the brick and tile are vividly displayed. At the same time, the blue wash wall along the moat river portrays a hydrophilic interface, which reflects the tranquility of the ancient city and makes the city dew through the difference between the inner and outer highlights. In addition, the high-brightness and rich lighting of key nodes such as Binyang Tower and Dongmen Gate make it an iconic landscape on the ancient city wall. Mr. Yu said that now, at night, the east gate of Jingzhou City is full of lights, standing in Jinfeng Square, and seeing the ancient city wall opposite to the light belt and the moat with blue light, they are just like each other. It is a combination of heaven and earth. After the completion of the project, Jingzhou City Housing and Urban-Rural Construction Committee and Jingzhou TV Station, Jingzhou News Network and other local media to organize the "Golden Lighting Cup's most beautiful Jingzhou Night Photo Photography Contest", collected more than 2,000 works showing Jingzhou Ancient City, Jingzhou City Governor The deputy secretary of the municipal party committee and other leaders of Jingzhou attended the award ceremony and presented awards to the award-winning photographers. Phoenix Portal, 21CN, and Hanwang reported on the entire event.

Innovations in lighting design concepts and methods: First, the design method principle: 1. Strictly control the brightness, light color and illumination of individual lighting to form an orderly nighttime landscape, with light colors such as white and warm white as the keynote to avoid blindly comparing brightness and color. 2. Highlight important monomers and key nodes, form regional logos, and give high-brightness or rich illumination to key nodes and important monomers, highlighting the characteristics of Jingzhou, such as Binyang Tower. 3. Highlight simple and atmospheric lighting style, promote the application of new technologies and green energy-saving facilities, improve the quality of overall lighting, apply new technologies, new technologies and lighting concepts. 4. It is strictly forbidden to use large-area colored floodlighting, color grooved lighting, color light-transmitting lighting and color decoration or pattern change during weekdays. 5. Strictly control the lighting of the facade of the building that affects the inner wall of the city wall. Through the difference of brightness inside and outside, the city dew is made. Second, the basic concept: 1. The three-dimensional spatial pattern of “forest, water, bridge and floorâ€. 2, "clear, show, elegant" architectural lighting methods. 3, "point, line, surface, layer" lighting expression. 4, "Emotion, interest, God" lighting mood. Butterfly valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal, radioactive media and other types of fluids.
The butterfly valve is a kind of regulating valve with simple structure, which can be used for the switching control of medium in low pressure pipeline. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing piece is a disc shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
Common parameters of butterfly valve:
Valve body material: stainless steel, carbon steel, cast iron, alloy
