Energy-saving regulating valve Low energy consumption Development direction
Energy saving to reduce energy consumption, improve energy efficiency is a development direction of the control valve. There are mainly the following development directions.
1. The use of low pressure drop ratio of the control valve. The proportion of the control valve in the entire system pressure drop is reduced, thereby reducing energy consumption. Therefore, the design of low pressure drop ratio of the control valve is one of the development directions, and the other development direction is the use of low impedance control valve. For example, a butterfly valve, an eccentric rotary valve, and the like are used.
2, the use of self-regulating valve: for example, the direct use of the pressure of the medium after the valve to form a self-control system, with the energy of the controlled medium to achieve pressure control after the valve.
3, the use of electric actuator control valve. Pneumatic actuators need to have a certain pressure during the operation of the entire control valve. Although small consumption amplifiers can be used, the gas consumption is still huge over time. The use of electric actuators, when changing the opening of the regulating valve, power supply is required, and power supply can no longer be supplied when the required opening is reached. Therefore, from the perspective of energy saving, electric actuators have obvious energy-saving advantages over pneumatic actuators.
4. Adopt piezoelectric regulating valve. The piezoelectric valve is used in the intelligent electric valve positioner, and the gas source is consumed only when the output signal increases.
5. The valve core with balanced structure is adopted to reduce the thrust or push torque of the actuator, reduce the air chamber of the membrane head and reduce the energy demand.
6, the use of frequency control technology instead of regulating valve. For the application of high voltage drop ratio, if the energy consumption is very large, the frequency conversion speed control technology can be adopted, and the frequency converter can be used to change the speed of the relevant operating equipment to reduce energy consumption.
Environmental pollution has become a public hazard, control valve on the environment pollution mainly control valve noise and control valve leakage. Among them, the control valve noise pollution to the environment is very serious.
1. Reduce the noise of the regulating valve. Various methods to reduce the noise of the control valve are developed, including the design of the control valve flow path to the design of the control valve trim, the analysis of the noise source to the measures to reduce the noise. The main design of noise reduction control valve and noise reduction control valve valve trim; reasonable distribution of pressure drop, the use of external noise reduction measures, such as increasing isolation, the use of silencers.
2. Reduce the air pollution of the regulating valve. Control valve of the air pollution refers to the control valve "run", "take", "drop", "leak", these leaks not only cause waste of materials or products, but also cause pollution to the atmospheric environment, and sometimes, will cause casualties or equipment explosion and other accidents. Therefore, the development of control valve packing structure and packing type, the development of the control valve seal will be an important research topic in the future.
Computer science, control theory and automation instrumentation, such as the development of high-tech science and technology to promote the development of the control valve, for example, the field bus control valve and intelligent valve positioner development, digital communication in the control valve to achieve. The development of the control valve has also promoted the development of other science and technology, such as the study of anti-corrosion materials, the study of methods to weaken and reduce noise, and the study of fluid dynamics. With the development of field bus technology, control valve will also be open, intelligent and more reliable, it will work with other industrial automation instruments and computer control devices together, so that the industrial production process control function is more perfect, the control precision is higher, the control effect is more obvious, and play a more important role in the modernization of our country.

How to install electric gate valve?
When using equipment, scientific installation is required. If the installation method is wrong, then the performance of the equipment is difficult to reflect, but also may cause harm to the equipment, so how to install the electric gate valve. In the installation of electric gate valve, the need to do the following, to be able to reflect its own value. First of all, before installing the gate valve, you need to read the installation instructions. If you do not read the relevant instructions when installing the gate valve, but only rely on the so-called experience and awareness to install, it is likely to make mistakes in installation. Shangzhou valve to remind the majority of users, electric gate valve installation needs to have a certain direction, need to pay attention to some details, if the installation of gate valve, need to use glue, then need to go through a period of maintenance, can be used. Therefore, when installing the electric gate valve, don't think how to install it, just blindly install it. Before safety, it is very important to learn the relevant installation knowledge.
What are the advantages of automatic control ball valve?
The automatic control ball valve is widely used in many fields, and it is naturally inseparable from its unique advantages. This kind of ball valve has the following excellent advantages: Advantage 1: The automatic control ball valve has good weather resistance. The automatic control valve can still maintain good working efficiency in various complex environments. Naturally, it is inseparable from the high temperature resistance, low temperature resistance, acid and alkali resistance of the automatic control valve. Therefore, the application range and field of this ball valve are relatively broad. Support the development of the national economy. Advantage 2: The working stability of the automatic control ball valve is high. After countless experiments, the Shangzhou valve continuously improves the working stability of the automatic control ball valve. Therefore, the ball valve provided by the company can support the stable and sustainable production of the enterprise. Advantage three: high precision, automatic control ball valve in the research and development, with high scientific and technological content, optimize material selection, optimize the internal design and focus on experiments, so that it has a high degree of precision, which is of great value for promoting the development of green economy.
What is the difference between globe valve and gate valve?
The valve is a control component in the fluid delivery system, with the functions of cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems, from the most simple cut-off valve to a very complex automatic control system used in a variety of valves, its varieties and specifications quite a wide range. Globe valves, gate valves, butterfly valves, check valves and ball valves, etc. These valves are now indispensable control components in various piping systems. Each valve is different in appearance, structure and even functional use. However, there are some similarities between the cut-off valve and the gate valve in appearance, and both have the function of cutting off in the pipeline. Therefore, there will be many friends who have little contact with the valve to confuse the two. In fact, if you look closely, the difference between the globe valve and the gate valve is quite large.
