Problems solved by technology

like figure 1 as shown, figure 1 The arrow on the left below represents fluid in, and the arrow on the right represents fluid out. Due to the use of a single air chamber, the movement and positioning speed of this structure is slow, and the positioning accuracy of the valve stem is low due to fluid pressure fluctuations and air pressure fluctuations.

Embodiment 1

[0025] Such as figure 2 As shown, a novel pneumatic intelligent positioner includes a valve stem 11, a positioning controller 6, a chamber with a movable partition inside, and the movable partition divides the chamber into two air chambers, the upper and lower chambers. One end of the valve rod 11 is arranged in the lower air chamber 9 and is connected with the movable partition; the positioning controller 6 is connected with the inlet valve 801 and the outlet valve 802 of the upper air chamber 8, and the positioning control The device 6 is also connected with the inlet valve 901 and the outlet valve 902 of the lower air chamber 9 . The valve core is arranged at the other end of the valve rod 11, figure 2 The arrow to the left of the middle spool represents the flow medium.

[0026] The valve stem 11 is a laminated piezoelectric ceramic valve stem, and a contact electrode 12 is provided on the valve stem, and the positioning controller 6 is connected to the contact electro...

Abstract

The invention relates to the field of valve locators, in particular to a novel pneumatic intelligent locator and an application method thereof. The novel pneumatic intelligent locator comprises a valve rod, a positioning controller and a cavity which is internally provided with a movable partition plate. The movable partition plate divides the cavity into an upper air chamber and a lower air chamber. One end of the valve rod is arranged in the lower air chamber and connected with the movable partition plate. The positioning controller is connected with an air inlet valve and an air outlet valve of the upper air chamber. The both-way pushing mode is adopted, the positioning speed is increased, meanwhile, the pneumatic positioning and laminated piezoelectric ceramic two-level positioning mode is adopted, and the positioning precision is improved.

Description

technical field [0001] The invention relates to the field of valve positioners, in particular to a novel pneumatic intelligent positioner and its use method. Background technique [0002] Regulating valve, also known as control valve, is a device that uses power operation to change fluid flow in a process control system. According to the implementation method, it can be divided into mechanical regulating valve, electric regulating valve, hydraulic regulating valve and pneumatic regulating valve. It has the advantages of simple structure, convenient operation, reliable use, easy maintenance, fire and explosion protection, and is widely used in large-scale process control fields such as metallurgy, chemical industry, textile, petrochemical, and pharmaceutical. Pneumatic intelligent valve positioner is a special control component of pneumatic control valve, which can improve the characteristics of the valve, improve the control accuracy and response speed. At present, almost a...
