Integration of electric valve or will become mainstream

Valves in industrial processes, mostly used to control all kinds of fluid and marching flow, such as water, oil, chemical liquid, etc. , is based on the parameters such as temperature, pressure and flow rate. National advocacy of saving energy and reducing consumption, gas market integration can become the mainstream of electric valve? Valve is everywhere in our life, it brings our lives a simple, safe. As valve technology has been developing continuously, perfecting the reform of the kinds of valve, the valve broadening the application field, and the matching valve standard is becoming more and more important and indispensable. Electric valve for liquid, gas and wind system pipeline medium flow of analog quantity adjustment, is AI control. In large valve and wind system control can do two switch control with electric valve. Electric valve is divided into two kinds, a kind of for quarter-turn valves electric actuator: from the Angle of the trip of electric actuator using with Angle of valve, valve within 90 - degree spin control pipe flow on and off; Another kind of valve electric device for direct travel: by straight travel electric actuator using with straight trip valve, valve plate up and down movement control pipe flow on and off. Usually on the high degree of automation equipment. Electric valve device has its own special requirements that must be able to limit torque and axial force. Electric valve device adopts usually limiting torque shafts. When the electric actuator specifications was determined, the control torque is determined. Generally run in a predetermined time, the motor will not overload. But as the following conditions may lead to overload: one is the low voltage power supply and can not get the required torque, the motor stop running; 2 it is wrong to set torque limit, make its torque is greater than the stop, cause continuously produce too large torque, the motor stop running; 3 it is intermittent use, the heat generated by the savings, more than the allowed temperature of the motor to appreciate; Four is a torque limit institutions circuit for some reason fails, the torque is too large; Five is the use of the environment temperature is too high, the relatively decreased motor heat capacity. Plant commonly used control valve with pressure reducing valve, pneumatic ball valves, electric ball valves, several type temperature control valve, etc. When choosing all kinds of automatic valve, should consider the types of heat engine, the requirements of precision, the quality of the control valve, pressure drop and flow rate and its structure, failure rate, manufacturer factors such as credit and after service, to achieve the goal of economical and practical. Integration of pneumatic, electric valve product itself has great advantages and development potential of space, to carry out some reform and innovation in after get the new development opportunity, progress very fast. In terms of operational efficiency and saves the energy, the use of automatic control valve is an indispensable part, traditional industry commonly used manual valve on the installation cost and efficiency than electric valve pneumatic valve. Media said electric valve as valve class market mainstream products. The current international economic situation is quite complex, steel, metal products export form severe in our country, if the valve casting industry want to get long-term development, boost domestic demand is inevitable. Domestic valve electric actuator product market with the continuous development of science and technology, also in the high technology, high parameters, high corrosion resistance, life direction.
