Abstract
A pneumatic control valve of a column type actuating mechanism belongs to the technical field of regulating valves and comprises a valve body, a valve cover, an actuating mechanism, a valve core and a valve rod, wherein the valve core and the valve rod are arranged in the valve body and valve cover. The bottom of the valve core and a valve seat in the valve body are arranged in matching mode, the upper end of the valve rod is connected and matched with the actuating mechanism, and the actuating mechanism comprises an upper membrane cover and a lower membrane cover. A membrane is fixedly arranged between the upper membrane cover and the lower membrane cover, a tray is arranged on the upper surface of the membrane and elastically connected with the upper membrane cover, the lower end of the tray is connected with a pulling rod connected with the upper end of the valve rod, and a group of columns are arranged between the lower membrane cover and the upper end of the valve cover. The pneumatic control valve of the column type actuating mechanism is simple in structure and reasonable in design, and the columns are arranged between the actuating mechanism and the valve covet, thereby reducing weight of the actuating mechanism, increasing installing space of accessories, enabling journey instructions to be convenient and clear, the overall structure of the pneumatic control valve to be light, handy and simple and the appearance to be attractive and elegant.
Description
Technical field
The utility model belongs to the modulating valve technical field, is specifically related to the pneumatic control valve of a kind of upright post type actuator.
Background technique
In recent years, the develop rapidly of domestic valve industry, the product structure type of each valve producer emerges in an endless stream.At present, domestic existing pneumatic control valve actuator adopts support frame type to be connected with valve gap, and the shortcoming of this frame connecting structure is: valve heaviness, volume are big, and difficulty of processing is big; Dismounting inconvenience must be rotated the ability dismounting of whole actuator; Annex installing space Shan is little, installs inconvenient; The stroke indication is prone to blocked by annex, observes thereby influence on-the-spot stroke indication.
The model utility content
To the problem that existing technology exists, the purpose of the utility model is to design the technological scheme of the pneumatic control valve that a kind of upright post type actuator is provided.
The pneumatic control valve of described a kind of upright post type actuator, comprise valve body, valve gap, actuator and be arranged on valve body and valve gap in spool and valve rod, described spool bottom is equipped with the valve seat that is arranged in the valve body; Described valve rod upper end connects and cooperates actuator; Actuator comprises membrane cover and following membrane cover, fixedly installs diaphragm between last membrane cover and the following membrane cover, and diaphragm upper surface is equipped with pallet; Pallet elasticity connects upward membrane cover; The pallet lower end connects push rod, and push rod is connected with the valve rod upper end, it is characterized in that fixedly installing one group of column between described membrane cover down and the valve gap upper end.
The pneumatic control valve of described a kind of upright post type actuator is characterized in that described membrane cover down bottom fixedly installs connecting plate, and described valve gap upper end fixedly installs pressing plate, and described column is connected with pressing plate with connecting plate respectively at two ends up and down.
The pneumatic control valve of described a kind of upright post type actuator is characterized in that the diameter of the diameter at described column two ends less than the column intermediate section.
The pneumatic control valve of described a kind of upright post type actuator is characterized in that described column upper end is threaded with connecting plate, after column lower end passes pressing plate, is connected with set screw nut.
The pneumatic control valve of above-mentioned a kind of upright post type actuator; Simple in structure, reasonable in design, between actuator and the valve gap column is set; Reduce actuator's weight; Increase the annex installing space, make the stroke indication convenient, clear, make that the pneumatic control valve overall structure is light and handy, short and sweet, beautiful appearance is generous.
