The pneumatic regulating valve uses compressing gas as the source of power, the cylinder as the actuator, and with the help of the valve positioner, converter, solenoid valve, preservation valve, gas storage tank, gas filter, etc.Or proportional adjustment, receive control signals of the industrial automation control system to complete the regulating pipeline medium: flow, pressure, temperature, liquid level and other process parameters.
Pneumatic regulating valve structure
The structure and operation of the pneumatic regulatory valve introduce the types of products in the market in the current market, which are subdivided according to the movement of the pneumatic regulating valve.One is the air -based pneumatic regulatory valve, and the other is the air -controlled pneumatic regulating valve.These two different types of+pneumatic regulatory valves are different from the structure and application fields of their working principles.The working principle of the air -on -type pneumatic regulating valve is that when the air pressure above the membrane head is increasing, the valve will move in the direction of the increase.When, the valve will show all the state of opening.When the air pressure becomes smaller, the valve will move towards this direction, and if there is no air input, the valve will be closed.The gas -controlled pneumatic regulatory valve it is the opposite of the structure of the gas -opening pneumatic regulatory valve. The greater the air pressure, the more the valve will move towards this direction.It will show a completely open state.
Well -known manufacturers of pneumatic regulatory valves
1. Siemens Siemens is a well -known brand of electronic and electronic engineering equipment in the world. Among them, the pneumatic regulating valve is also one of the products, and it is the leader in this field in Germany.It laid a solid foundation in China.Second, Shanwu Shanwu Group is a large enterprise in Japan. Its products include a variety of products, including the sales point of controlling equipment.In recent years, Shanwu Group takes the instrument and control as its main core, and places the fundamental concept of saving energy, resources, effort and money. The design and production of the pneumatic regulating valve is very popular.Use.Third, Zhengliang introduced the two foreign aerodynamic regulatory valve manufacturers. Is it not good in China? Actually, there are many good air -regulating valve manufacturers in China, including Shanghai Zhengliang Valve Co., Ltd., this companyThe products are also preferred in China. Lets take a look at the companys information.
Performance valve work principle
The working principle of the pneumatic regulating valve: The regulating valve is used to regulate the flow, pressure, and liquid level of the medium.According to the regulating site signal, the opening of the valve is automatically controlled to achieve regulation of the medium flow, pressure and liquid level.The regulating valve is divided into electric regulating valve, pneumatic regulatory valve and liquid dynamic regulating valve.The regulating valve consists of two parts: electric execution agency or pneumatic execution agency and regulating valve.The regulating valve is usually divided into two types: direct single -seat regulatory valve and the direct two -seater regulating valve. The latter has the characteristics of large circulation capacity, small unbalanced handling, and stable operation.There are few occasions.
