[0002] The valve positioner is divided into pneumatic valve positioner, electro-pneumatic valve positioner and intelligent valve positioner according to the structure. It is the main accessory of the regulating valve and is usually used in conjunction with the pneumatic regulating valve. It receives the output signal of the regulator and then uses its output signal to control the pneumatic regulating valve. When the regulating valve is actuated, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal. The installation of the valve positioner requires the use of an installation component, that is, an installation base plate. The installation base plate of the prior art needs to be installed by disassembling the outer shell of the valve positioner and using bolts to pass through the outer shell. It is inconvenient to operate, and after the bolts are installed, the firmness of the bolt installation cannot be better guaranteed. For this reason, we design a valve positioner installation component. Summary of the invention
