Social development is inseparable from the economic construction of basic industries. Over the past 40 years of reform and opening up, China's industrial production level has been significantly improved, and the market has formed a virtuous cycle mechanism. Especially for industrial products such as valves, the market is optimistic. The sales of products such as regulating valves have increased sharply, and the product technology has been improved more and more. The tightness of the regulating valve directly affects the performance and service life of the product, especially for some key industrial and mining enterprises. In addition to the debate, the international community is more important to support China's development. Especially since the epidemic, considering the actual di

How to adjust the pressure relief valve group of the concrete pump truck correctly? In the construction process, if the operators move disorderly due to their unclear understanding of the performance of each part of the concrete pump truck, it will easily lead to various faults in the operation of the concrete pump truck, which will bring a lot of inconvenience to the on-site construction. Generally, the regulation of pressure relief valve group, as an essential step in the operation process, also plays an important role in the whole construction process. 1、Overflow valve regulation When adjusting the pressure relief valve group, first adjust the condition of the overflow valve through the following steps: first loosen the adjusting rod of the superimposed overflow valve u

As my country's industrial development continues to deepen, the requirements for automation of electrical equipment in industrial production are getting higher and higher. The stable and long-term development of enterprises is inseparable from the support of advanced electrical automation instruments and automation control technology. The scale of industrial production continues to expand. The development of industrial electrical automation instrumentation is stable. The working principle of industrial automation instruments is to use intelligent methods to collect and monitor the information in the production process, which can help the production work to be completed more accurately. Inspection in the production process is a very important link for industrial production, and ind

In recent years, the sales volume of liquid ammonia emergency shut-off valve shows the trend of high-speed explosion, and its application scope covers many different fields such as mining, petroleum, chemical industry and so on. The following briefly introduces how to achieve good explosion-proof performance of liquid ammonia emergency shut-off valve: 1、The shell material has the explosion-proof effect of gas explosion pressure Compared with other types of solenoid valves, liquid ammonia emergency shut-off valve has better explosion-proof performance because its shell material has the explosion-proof effect of gas explosion pressure. Most shell materials are made of metal frame and flame retardant and high temperature resistant resin. These two materials play a very impor

   With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i

Even if the water pump manufacturer uses high-quality raw materials and processes to manufacture the water pump, there will still be some abnormalities in the long-term use of the stainless steel diaphragm pump. Among them, the vibration of water pump is common, and there are many reasons for the vibration of unit and pump house building. Specifically, the following reasons will lead to the vibration of stainless steel diaphragm pump: 1

As an important part of my country's manufacturing industry, the instrument and meter manufacturing industry has played an important role in promoting the country's economic growth and social development. With the continuous development of social economy and technology, my country's instrumentation industry has been advancing all the way in recent years. How much do you know about instrumentation! Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In detail, instruments and meters have functions such as automatic control, alarm, sig

The automatic adjustment system of the industrial production process is generally composed of a detector, a regulating valve, an actuator and an adjustment object, and the actuator is an indispensable and important part of it. As the terminal product in the industrial process control system, it plays an irreplaceable role for other products in the automatic control system. From the perspective of the industry, the development speed of the implementation of electric control valves in my country lags behind other control instruments. However, this phenomenon is being changed. Not long ago, China Machinery Industry Federation and China General Machinery Industry Association held a product appraisal of "Hydraulic Actuator for Tank Root Valve and Electro-hydraulic Actu

In the face of so many valve classification and so complex conditions, to choose the most suitable valve for pipeline system installation, we should first understand the characteristics of the valve; Secondly, we should master the steps and basis of valve selection; Furthermore, we should follow the principle of selecting valves for petroleum and chemical industry. The principle of selecting valves in petroleum and chemical industry: the flow passage is straight through valve, which has small flow resistance, and usually is used as cut-off and open medium valve; The valve which is easy to adjust the flow is used to control the flow; Plug valve and ball valve are suitable for reversing and diverting; The valve with wiping function is suitable for medium with suspended particles.

The green development of industry needs innovation. Without innovation, the industry will not progress, and the goal of enterprise development will be difficult to achieve. Green development is not only the need of ecological civilization construction, but also the need of China's development in the new era. The high-quality development of social economy and the improvement of the quality of people's living environment must depend on the industrial progress. If the industrial production mode is relatively backward, such as the problem of dripping and running in the production process, it will produce relatively serious pollution problems, and the development goals of clean production and green industry can not be achieved. In the pharmaceutical industry, if the performance of the
