Abstract

The utility model discloses the online inspection intelligent pneumatic actuator of pneumatic adjustable valve. The utility model is provided with an intelligent localizer in the bracket under the pneumatic actuator membranes head and is provided with a position transducer which is used to detect the signals of the position of the inspection valve on the pushing rod inside the bracket. The utility model is characterized in integrating the pneumatic actuator and the intelligent localizer together and avoiding the measuring deviation that is caused by the conversion of direct and the angular travels.

Description

Online detection intelligent pneumatic power actuator
Technical field
The utility model belongs to the pneumatic control valve technical field.Be particularly related to the online detection intelligent pneumatic power actuator of a kind of pneumatic actuator and positioning work piece one.
Background technique
The intellectuality of present domestic control valve mainly shows as: control valve itself does not become, be equipped with intellective electropneumatic valve positioner after, realize the intellectuality of control valve.Its intelligent positioner is all as the annex of modulating valve, individualism.The shortcoming of this kind structure is mainly: position feedback is to be converted to the angle stroke by the feedback rod straight journey, send the control that central processing unit (CPU) (CPU) is realized valve position to by position transducer again, because straight, angle conversion has increased measurement error, thereby high-precision intelligent positioner is very high to the requirement of position transducer.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned technology, the online detection intelligent pneumatic power of the modulating valve that provides a kind of intelligent positioner and pneumatic actuator to combine together actuator.
The utility model is realized with following technological scheme: a kind of online detection intelligent pneumatic power actuator, and it is made up of pneumatic actuator and intelligent positioner two parts; Pneumatic actuator comprises the support of film head, film subfacies, is contained in the push rod in die head and the support; Intelligent positioner partly comprises microprocessor CPU with communication function, position transducer etc., it is characterized in that, the support of film subfacies is totally-enclosed support, the intelligent positioner device is integral with pneumatic actuator in totally-enclosed support, and the position transducer that detects valve position signal is installed on the interior push rod of support.
By having adopted technique scheme, the beneficial effects of the utility model are: positioning work piece and pneumatic actuator are combined together, and positioning work piece is not re-used as the independent annex of modulating valve, more convenient use.The position transducer that detects valve position signal is directly installed on the push rod in the support, has eliminated the measurement error that former external positioning work piece straight journey, the conversion of angle stroke cause, improved measuring accuracy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model profile schematic representation;
Fig. 2 is the utility model structural representation.
Among the figure: 1, film head, 2, support, 3, push rod, 4, position transducer.
Embodiment
As shown in Figure 1, comprise film head 1 and be positioned at support 2 below the film head 1 that at the utility model support 2 is a totally enclosed type, can establish display screen or display window thereon.
As shown in Figure 2, pneumatic actuator adopts no many springs of external pipeline film pneumatic actuator, for prior art, do not describe in detail.The intelligent positioner device is in totally-enclosed support 2.Position transducer 4 directly is assemblied on the push rod 3, directly detects valve location, thereby has overcome the measurement error that conversion causes between original technology straight journey, angle stroke.
