In recent years, with the development of mechatronics, electric valve, the premier mechanical commodity, has ushered in an unprecedented mall. Electric valves are more economical and reliable than traditional valves (manual valves, pneumatic valves). Electric valves are indispensable today in the increasingly high voice of environmental protection and safety. Infinite shopping mall demand for electric valves is also increasing. Electric valves are used in a wide range of applications, including petroleum, chemical, electric power, nuclear power, metallurgy, ships, light industry, food, and municipal. As far as the product itself is concerned, the electric valve has the advantages of simple installation, low failure rate, and the advantages of the automation needs of the industry, which is a more cost-effective choice for the industry. Because of the use of conventional pneumatic valves, it is inevitable that piping, solenoid valves and compressors will succeed. The electric valve is driven by a motor, the device is simple and labor-saving, and the electric valve device can be placed in the factory's original self-control line, which can save other costs.
In addition, the motor drive method is smoother to open and close, and there is no defect that the instantaneous impulse is too large, and the failure rate can be greatly reduced. The petrochemical profession mainly chooses the gate valve, globe valve and check valve of API specification; the power part mainly selects the high temperature pressure gate valve, the stop valve, the check valve and the safety valve for the power station and the low pressure butterfly valve and gate valve of a part of the water supply and drainage valve; Stainless steel gate valve, globe valve, check valve. Metallurgical occupations mainly use low-pressure large-diameter butterfly valves, oxygen shut-off valves and oxygen ball valves; urban construction parts mainly use low-pressure valves, such as the large-diameter gate valves that are the primary choice for urban tap water pipelines, and the main selection of mid-line butterfly valves for building construction. Metal sealing butterfly valves, etc.; oil pipelines mainly use slab gate valves and ball valves; pharmaceutical occupations mainly use stainless steel ball valves; food occupations mainly use stainless steel ball valves.
Electric valves are a new type of valve occupation, so the prospect of electric valve shopping malls is very broad. Forging companies should learn more about this profession, supply forged parts for this profession, and use the emerging profession of electric valves to develop their forging career. Get a new driving force. Following the changes in the mall, the electric valve products also changed accordingly. For example, following the development of oil development to inland oil fields and offshore oil fields, and the power industry from thermal power of less than 300,000 kilowatts to thermal power and hydropower and nuclear power of more than 300,000 kilowatts, the performance and parameters of electric valve products should also be modified according to changes in equipment application fields. The urban construction system will use a number of low-voltage electric valves, and will be carried out in an environmentally-friendly and energy-saving manner, that is, the low-pressure iron gate valve used in the past will gradually shift to the environmentally friendly rubber plate valve, balance valve, metal sealing butterfly valve and midline sealing butterfly valve. The oil and gas transmission projects are carried out in the direction of pipelines, which in turn requires many slab gate valves and ball valves. The construction of the power station is going to be large-scale, so it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves. It is also necessary to use the rapid opening and closing of electric valves. For the needs of complete sets of projects, the supply of electric valves is from a single type to a variety of types and multi-standard development. The electric valve required for an engineering project is becoming more and more popular by an electric valve manufacturer.
In the future, electric valves will continue to develop in the direction of high technology content, high parameters, strong corrosion resistance and high life.
