The butterfly valve with electric actuator D67A1X-10ZB1 is an important driving force for the electrically adjustable resilient seated wafer butterfly valve, and its model selection determines the actual on-site operation of the product. At the same time, there are some specific selection criteria for the selection of the electric actuator. It is mainly considered from aspects such as the operating torque, the structure of the main unit, the full rotation of the output shaft, and the output rotation speed. The more detailed principles will be shared below:
The operating torque is an important parameter for selecting the valve electric device. The output torque of the electric actuator should be 1.2 to 1.5 times the maximum operating torque of the valve.
The main unit structure of the wafer butterfly valve YD37A1X3-10Q electric device is divided into two types: without a thrust disc configuration and with a thrust disc configuration. The main difference between the two is whether the torque is directly output or converted through the valve stem nut in the thrust disc.
The number of rotation turns of the output shaft is related to the nominal diameter of the valve, the pitch of the valve stem, and the number of thread starts. The total number of rotation turns that the electric device should meet = the opening height of the valve / the number of thread starts of the valve stem × the pitch of the valve stem transmission thread.
The selected diameter of the valve stem should be allowed to pass through the electric device. That is to say, the inner diameter of the hollow output shaft of the electric device must be larger than the outer diameter of the valve stem of the rising stem valve. At the same time, to ensure that the electrically adjustable butterfly valve can work normally after assembly, the diameter of the valve stem and the size of the keyway also need to be appropriately selected.
The output rotation speed needs to be appropriate. If the opening and closing speed of the valve is too fast, it is likely to cause the water hammer phenomenon. Therefore, it should be selected according to the actual usage situation.
The above are the issues that need to be noted when selecting the valve electric actuator of the electrically adjustable wafer butterfly valve. In terms of packaging and transportation, there are also some points that need attention regarding the valve electric device equipment. First of all, the packaging of the electric device equipment such as the valve electric actuator should have rainproof, moisture-proof, and dust-proof measures, and the packaging should be firm and reliable. After receiving the goods, it should be installed immediately. If it needs to be placed for a certain period of time, the storage environment should be kept ventilated and dry, and it should not be stored outdoors. At the same time, it is prohibited to carry out debugging and maintenance on rainy days. After the pressure test is completed, all the fasteners should be tightened again to ensure that the electrical part is tightly sealed, prevent rust and wear, and avoid affecting the later use.
The valve electric actuator of the electrically adjustable butterfly valve (Double flanged butterfly valveFlanged concentric butterfly valve Manufacturers & Suppliers – China Flanged concentric butterfly valve Factory (tws-valve.com) is an indispensable device for realizing the program control, automatic control, and remote control of the valve, and its movement process is controlled by the magnitude of the stroke, torque, or axial thrust. Correctly selecting the valve electric device is crucial to preventing the occurrence of overload phenomena.
