Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.
The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.

From furniture to decent furniture, from furniture to buying and selling furniture, from Sichuan to Sichuan, from self-production to global... 60 years, Sichuan furniture industry has grown from scratch, 60 years, a finger The historical moment, the ever-developing furniture industry, has had a high-speed leap and upgrade in such a 60-year period. Among the many manufacturing industries in Sichuan, the furniture industry, which has been listed as a key support development industry by the Sichuan Provincial Government in recent years, has more than 5,000 furniture manufacturing enterprises, and is known as the “China's three major furniture production basesâ€. The scale and quantity of furniture stores are the highest in the country. The number of furniture industry industrial parks is also among the best. There are many furniture brand predators: Wang Xuemao and his eightyi furniture factory; Wang Jianbin and his palm jewel; Zhang Youquan and his all-friends Private; Yin Xianjian brothers and his double tiger furniture; and good scenery, nine days, Shuangfeng, Ai Fan, Langdu, Xiongfeng, Haodi, Xiangnan Lin, Tianzi and other furniture brands, are also famous. According to statistics, in 2008 alone, the output value exceeded 30 billion. Some people in the industry expect that after the end of 2009, the annual output value of “Sichuan Made†furniture will exceed 36 billion yuan, and the output value of furniture in Sichuan will reach 40 billion yuan in 2010. Behind this miracle, there are nearly 500,000 large-scale employees. As the mainstay of the furniture industry, they not only support the magnificent improvement of the Sichuan furniture industry, but also witness the tremendous changes brought about by the acceleration of the reform and opening up process and the rapid development of the social economy. In the early days of the founding of New China, the furniture was an old thank-you, and it was such an old furniture man who had worked for nearly 50 years. In his memory, the home at that time was a cottage, and there was no reasonable planning for the auditoriums of modern houses. Even the furniture was pitiful. Ordinary people are a table, two long benches and a bed. The so-called bed is a large wooden table with four feet. Some even use a fire brick to lay the wooden board and then spread the grass on the wooden board. After that, cover it with a layer of mat. If the mat is not covered, it will reveal some irregular grassy edges. "In that era, there was a cabinet in the house, and many of the tables were nailed with wooden strips. There was no place to buy furniture, let alone a furniture factory!" In Sichuan, because of the unique bamboo resources, there are The skillful master will cut down the bamboo and weave it into various rattan baskets, rattan chairs, etc. Compared with wooden furniture, rattan furniture is more popular at this time. In the 1960s and 1970s, wood was supplied with indicators. In the early 1960s, Chengdu had eight furniture production cooperatives, which were composed of carpenters from various societies. Since the plates, steel and infrastructure materials were purchased and sold by the state at that time, the cooperatives purchased a certain amount of wood by ticket and made the furniture and then sold it. However, due to the limited number of furniture, it could not satisfy the living needs of all ordinary people. Especially in the early 1970s, the production of the furniture industry was greatly affected by the environment and the output was plummeted. The "36" foot furniture set consisting of a dressing table, a bench and a large wardrobe became the unforgettable memory of the married women. Lao Xie said: "At that time, the tools for furniture were an axe, a saw, two planes, a curved ruler and an ink box. The wood saws are long, thick and thick, and are stretched with ink lines. Under the line saw. At that time, the furniture did not look like it, regardless of the design, as long as it was made, someone would buy it.†In the 1980s and 1990s, the reform and opening up of the red furniture industry in 1984 and 1985, allowing individuals to apply for business licenses, let the old Xie excited Up, according to the policy, the furniture factory can only be named according to the name of the place, and Lao Xie’s “Muziqiao Furniture Factory†took a formal first step. At that time, there was a rule that a private boss should not employ more than seven workers. So, Xie Xie will only have 300 yuan in his body to do all his venture capital, rent a 200 square meter street-facing pavement in a ring road, 150 yuan a month's rent is not cheap, to know that time, A worker’s salary is only three or forty yuan. Lao Xie picked up some wood from the acquaintances of the lumber mill, and eight people began to start the stove. Recalling the situation at the time, Lao Xie said: "Three-door wardrobe 360 ​​yuan, bed 320 yuan, dressing table 80 yuan ... the most foreign is veneer furniture, and the industry is backward, we can only use the most earthly way to work The lacquer used for the lacquer water, and the veneer is glued with the latex, then the edge of the fire brick is pressed, the sand is laid in the middle, and it can be dried for more than one day. Near the 90s, the Polaroid board also appeared. The better furniture is to put the Polaroid board on both the front and the back of the furniture. The two sides are smooth and look very advanced. People who move to a new home can buy a full set of veneer furniture and put a radio. It feels better than driving a Mercedes-Benz BMW. Also in the mid-1990s, with the help of the exhibition economy, the furniture industry has brought about two development opportunities. The nationwide exhibitions such as Beijing Furniture Fair, Shanghai Furniture Fair and Guangdong Furniture Fair have greatly promoted industry exchanges and products. Strongly drove the development of the industry. Once, a middle-aged man from Deyang walked to the exhibition hall of Lao Xie and asked for the best furniture. So now, Lao Xie still clearly remembers the first set of high-end furniture he sold, and the customer counted at the time. After a few days of thinking, Lao Xie added a Phnom Penh design to the veneer furniture, and after the delivery, the customer liked it very much. He was very happy with the payment of more than 1,000 yuan. Since 2000, the scale development of brand clusters has been “Sichuan furniture was not designed in the 1980s, Guangdong in the 1990s, and exhibitions abroad in 2000. Now, most well-known furniture has its own professional design and development team, and some even with foreign countries. Designers cooperate and develop! Not to mention the carpenter's self-employment, to the scale of the product sales network in the country, as well as the government's support and planning of the furniture industry park," Xie sighed: "Change is too big. The upgrade, transformation, and brand awareness gradually made the small furniture factories gradually form a large enterprise with brand influence, and the major home stores not only have European, American, simple, classical, Chinese and other styles. The combination of various materials such as plate, solid wood, rattan, wrought iron, glass, stone, and soft body makes consumers more eye-catching; TV, newspapers, networks, street signs, buses, etc. are constantly publishing various furniture brands. Propaganda; buyers from outside the province, and even abroad, continue to extend the olive branch to Sichuan furniture companies. All this means that the development of the Sichuan furniture industry has entered another new stage. From the manual production of carpenters, to small workshop production, to large-scale factory production, the Sichuan furniture industry that has completed the “triple jump†is constantly innovating, and it indicates that the future development of the Sichuan furniture market will be even more in full swing.
