Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] The invention provides an intelligent valve positioner, which includes a piezoelectric module. refer to figure 1 , figure 1 Illustrated is a schematic cross-sectional view of the intake chamber of the piezoelectric module of the intelligent valve positioner of the present invention. The upper part of the intake chamber 1 is provided with an air inlet 11, and the lower part is provided with an air outlet 12. The piezoelectric module also includes Sealing ball 2 for sealing or opening the air inlet of the air inlet chamber 1. In this embodiment, the air inlet 11 is a tapered hole whose section diameter gradually increases along the ...

Abstract

The invention provides an intelligent valve locator comprising a piezoelectric module. The piezoelectric module comprises an air inlet cavity provided with an air inlet and an air outlet, and a sealing ball used for sealing or opening the air inlet of the air inlet cavity. The air inlet is a tapered hole, and the section diameter of the air inlet is gradually increased along the air inlet direction. The sealing ball is supported by a reset spring and can be movably arranged in the air inlet along the axis direction of the air inlet. The diameter of the sealing ball is larger than or equal to the minimum section diameter of the air inlet, and smaller than the maximum section diameter of the air inlet. The sealing ball is made of aluminum alloy materials. The sealing ball made of the aluminum alloy materials is good in oil resistance, water resistance and expansion resistance and long in service life, so damage of the piezoelectric module caused by oil intrusion and water intrusion problems can not occur, maintenance cost is reduced, work efficiency is improved, and application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of automatic control, and more particularly relates to an intelligent valve positioner. Background technique [0002] The intelligent valve positioner, also known as the pneumatic valve positioner, is the main accessory of the control valve. It is usually used in conjunction with the pneumatic control valve. It receives the output signal of the regulator, and then controls the pneumatic control valve with its output signal area. When the control valve After the action, the displacement of the valve stem is fed back to the valve positioner through the mechanical device, and the valve position status is transmitted to the upper system through the electrical signal. [0003] The intelligent valve positioner is based on microprocessor technology and uses digital technology for data processing, decision making and two-way communication; Converted to a pneumatic signal to control the actuator. The pneumatic part...
