Structural characteristics and working principle diagram of electric angle control valve
The electric angle control valve usually adopts the flow direction of the open type (that is, the bottom enters and the side exits), and the electric actuator contains the feeding function, which accepts a unified 4-20mA or 1-5V·DC standard signal, and converts the current signal into phase. The corresponding linear displacement automatically controls the opening of the regulating valve to achieve… -
Method for preventing corrosion of valve and its parts
As we all know, the corrosion damage of metal has a considerable impact on the service life and reliability of the valve. The influence of mechanical and corrosive factors on metals greatly increases the total wear of the contact surfaces. The total amount of wear on the friction surfaces of the valve during operation. During valve operation, friction surfaces can wear and be damaged due to simult… -
Basic introduction of swing check valve
What are the three types of swing check valves? A valve that opens and closes with the force of the medium flow to prevent the backflow of the medium is called a check valve. Check valves belong to the category of automatic valves. Mainly used in pipelines where the medium flows in one direction, allowing the medium to flow in only one direction to prevent accidents.… -
Globe valve types and features
This type of globe valve is designed in strict accordance with the ASMEB16.34 standard; the connection between the valve body and the bonnet, the installation of the stuffing box, the valve stem nut, and the upper seal are all designed in strict accordance with API600. The valve material selection fully complies with API600 requirements. The structural length conforms to ASMEB16.10; the flange con… -
How to do the maintenance and maintenance of the Silent check valve
The silent check valve belongs to the automatic valve category. Its function is to prevent the backflow of the medium in the pipeline. It is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.… -
Dynamic diagram of application characteristics and working principle of pneumatic double-seat control valve
Pneumatic double-seat control valve, as the name implies, has two valve cores and two valve seats in the valve body. It adopts a double-guide structure and is mainly composed of a multi-spring straight-stroke pneumatic actuator and a straight-through double-seat control valve body. The pneumatic double-seat control valve is generally used. Under the requirement of pressure compensation, the pressu… -
The working principle of the y-type Strainer and the correct installation method
The Y-type filter is mainly composed of a connecting pipe, a main pipe, a filter screen, a flange, a flange cover and a fastener. When the liquid enters the filter basket through the main pipe, the solid impurity particles are blocked in the filter blue, and the clean fluid passes through the filter basket and is discharged from the filter outlet.… -
The principle and function of electric regulating valve
Electric regulating valve is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pneumatic control valve, it has obvious advantages: the electric control valve is energy-saving (only consumes electricity…
