It is understood that the reason why this patented product can help the Olympics is that it has the characteristics of no rust, corrosion resistance and non-fouling, which can effectively prevent the fire valve from opening due to the blockage of a small amount of impurities in the water pipe, thus ensuring the valve Closed reliability. Due to its structural design and material application, the traditional fire-fighting solenoid valve must be inspected and cleaned every six months after installation. The "floating spool fire-fighting solenoid valve" can be normally immersed in water for a long time due to the unique principle of opening and closing and structural design. It is used, and it does not require regular maintenance after installation. It is a critical component of the large space intelligent active sprinkler system equipment.
Cai Songcheng, general manager of Hainan Fucheng Energy Saving Valve Manufacturing Co., Ltd. is the holder of the patent. He now has 10 utility models or invention patents. Last year, he was named one of the top ten patent inventors in the province. According to its introduction, the utility model patent product “floating spool fire-fighting solenoid valve†has been applied in 135 venues, exhibition centers, hotels, shopping malls and office places in 22 provinces and cities such as Beijing, Tianjin, Shanghai and Guangdong.
Cai Songcheng was born in Shantou in his 40s. In 1976, he graduated from high school and went to work in Tongan, Hainan. Since then, he has had an indissoluble bond with Hainan. He has the spirit of hard work and dedication of the Shantou people, and he is doing a jewellery business in Hainan. More than 10 years ago, his jewelry store was almost all over the big shopping malls in Haikou.
In October 1997, Cai Songcheng closed all the jewelry stores under his name, took out all the funds, and began to play the banner of Hainan Fucheng Energy Saving Valve Manufacturing Co., Ltd. He decided to put the rest of his life on the research and development of valves.
In 1999, he successfully patented a faucet. Cai Songcheng continued to carry out technological transformation, and immediately applied for three patents, all of which were authorized. He decided to extend the "floating spool" technology extension to the valve field. After more than a year of hard work, he applied for four patents and all were authorized. In 2000, it was included in the “National Spark Program Project†and “National Key New Product Plan Project†by the Ministry of Science and Technology; it was included in the “2000 Construction Science and Technology Achievements Promotion and Transformation Guide Project†by the Ministry of Construction. Last year, he was named the top ten patent inventor of Hainan Province.
The color mixer can mix a variety of materials into a uniform mixture, such as cement, sand, crushed stone and water into wet concrete; It can also increase the contact surface area of materials to promote chemical reaction; It can also accelerate physical changes, such as adding solvent to granular solute, and accelerating dissolution and mixing through the action of mixing machinery.
Commonly used color mixers are divided into four categories: gas and low-viscosity liquid mixers, medium-high viscosity liquid and paste mixing machines, thermoplastic material mixers, and powder and granular solid material mixing machines. The gas and low viscosity liquid color mixing machine is characterized by simple structure, no rotating parts, small maintenance and low energy consumption. This type of mixing machinery is divided into four types: air flow mixing, pipe mixing, jet mixing and forced circulation mixing.
The color mixing machine of medium and high viscosity liquid and paste generally has strong shearing effect; Thermoplastic material mixer is mainly used for mixing thermoplastic materials (such as rubber and plastic) with additives; The mixing machines for powdery and granular solid materials are mostly intermittently operated, and also include machines with mixing and grinding functions, such as wheel rolling machines. During mixing, all materials involved in mixing shall be evenly distributed. The degree of mixing can be divided into three states: ideal mixing, random mixing and complete non-mixing. The mixing degree of various materials in the mixing machine depends on the proportion, physical state and characteristics of the materials to be mixed, as well as the type of mixing machine used and the duration of mixing operation.
The mixing of liquid mainly depends on the mechanical stirrer, air flow and the jet of the liquid to be mixed, so that the materials to be mixed are stirred to achieve uniform mixing. Stirring causes part of the liquid to flow, and the flowing liquid pushes the liquid around it, resulting in the formation of a circulating liquid flow in the solvent. The resulting diffusion between liquids is called the main body convection diffusion. When the liquid flow velocity caused by agitation is very high, there will be shear action at the interface between the high-speed liquid flow and the surrounding low-speed liquid flow, thus generating a large number of local vortices. These vortices spread rapidly around and bring more liquid into the vortex. The turbulent convection diffusion formed in a small range is called eddy diffusion.
The mixing mechanism of a small amount of insoluble powdery solid and liquid is different from the density component, and the mixing mechanism of immiscible liquid is the same, but stirring cannot change the particle size of powdery solid. If the settling velocity of solid particles cannot be less than the flow velocity of liquid before mixing, no matter what mixing method is used, it will not form a uniform suspension.
The mixing of different pastes is mainly to divide the materials to be mixed repeatedly and make them subject to the strong shearing effect caused by the actions of pressing, rolling, squeezing, etc., and then merge and knead repeatedly to reach the required mixing degree. This kind of mixing is difficult to achieve ideal mixing and can only achieve random mixing. The powdery solid is mixed with a small amount of liquid to form a paste, and its mixing mechanism is the same as that of paste material.
Recently, the reporter learned from the Provincial Intellectual Property Office that the utility model patent product “Floating Spool Fire-fighting Solenoid Valve†produced by Hainan Province enterprises was favored by the construction unit of the 2008 Beijing Olympic venues and was installed in the Digital Beijing Building. Olympic venues such as the Olympic Swimming Center and the Olympic Beichen Conference Center have also selected this product in engineering design.
