Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 5 as can be known; the utility model is equipped with copper water joint 1 and baffler 10 outside box body 2; inside is equipped with to become and is sent plate 6, connecting plate 7, manifold valve 8 and inserted block 9; sprue 13 is equipped with in the below of connecting plate 7, and mainboard 3 is equipped with in the top of connecting plate 7, and safety cover 4 is equipped with in mainboard 3 tops; manifold valve 8 one sides are equipped with valve plate 11; valve plate 11 has valve port 12, and linear displacement transducer 5 is installed on the pneumatic actuator outside the box body, and is connected with copper water joint 1 by lead.
Described linear displacement transducer 5 is installed on the pneumatic actuator outside the box body, be fixed in the actuator by 2 fixing clamps, linear displacement transducer 5 and actuator be by the connecting rod mechanical connection, and it is electrically connected cable and is connected on the terminal row on the mainboard 3 by copper water joint 1.
Described intelligent control part and linear displacement transducer 5 partial installations, the electrical cable of linear displacement transducer 5 are connected in by copper water joint 1 on the terminal row on the mainboard 3 of intelligent control part.
The utility model intelligent valve positioner comprises two-part, is respectively intelligent control part and linear displacement transducer 5.Intelligent control part is away from actuator body, can make things convenient for execute-in-place and away from abominable applied environment, can realize telecontrol and local operation respectively, parameter, function setting and local operation are realized by four buttons on the positioning work piece mainboard 3 and liquid crystal screen.Intelligent control part comprises intelligent controller and electrically-controlled valve, and electrically-controlled valve is made up of manifold valve 8, valve plate 11 and baffler 10, realizes the pneumatic function of three-position five-way, middle envelope, connects the double-action pneumatic actuator.Intelligent controller send plate 6 to form by mainboard 3, connecting plate 7 and change, is connected by winding displacement each other, can realize automatically and manually control, can realize outage and protection when losing signal function.
Be its working principle below:
Shown in Fig. 5 intelligent valve positioner fundamental diagram, intelligent valve positioner is made of intelligent controller, electrically-controlled valve and valve position sensor three parts, wherein valve position sensor is a linear displacement transducer 5, the electrically-controlled valve part is made up of manifold valve 8, valve plate 11 and baffler 10, and mainboard 3, change send plate 6 and connecting plate 7 to form intelligent controllers.Intelligent controller is accepted the duty setting signal of 4-20mA, compare with the actual valve place value of linear displacement transducer 5 feedbacks, if detect deviation, give electrically-controlled valve according to automatically controlled instruction of size and Orientation output of deviation immediately, electrically-controlled valve and then the air mass flow of regulating turnover actuator air chamber, like this, electrically-controlled valve is converted to pneumatic displacement increment with control command.When actual valve position and setting value deviation are very big, continuous signal of intelligent controller output; Little as deviation, intelligent controller is with output pulse signal; When deviation is very little, then there is not framing signal output, the valve physical location arrives setting value, and pneumatic actuator reaches state of equilibrium.
In the process of intelligent valve positioner work, air door, valve is connected on the pneumatic actuator, pneumatic actuator is driven by the source of the gas of electrically-controlled valve control, be electrically connected the terminal row of cable by copper water joint 1 access positioning work piece mainboard 3, partial installation on pneumatic actuator the signal of linear displacement transducer 5 be input to become and send plate 6, it gives mainboard 3 with the valve opening position feedback in the actual loop, program in the mainboard 3 is by calculating, control manifold valve 8 is regulated the air mass flow of turnover actuator air chamber, makes pneumatic actuator driving air door or valve opening to preposition accordingly.When actual valve position and setting value deviation are very big, mainboard 3 will be exported a continuous signal, and transmit it to manifold valve 8; Little as deviation, mainboard 3 is with output pulse signal; When deviation was very little, 3 of mainboards did not have framing signal output, and the valve physical location arrives setting value, and pneumatic actuator reaches state of equilibrium.Connecting plate 7 connects mainboard 3, becomes and send plate 6 and manifold valve 8; interference and destruction that safety cover 4 protection mainboards 3 are exempted from ambient conditions; inserted block 9 is used for the location of valve plate 11 and manifold valve 8; valve port 12 is connected with the air chamber of actuator by pipeline; baffler 10 is eliminated the noise that produces in manifold valve 8 adjustment processes, and box body 2 is used to protect and be connected and fixed each constituent element of intelligent valve positioner inside.
