First , structure characteristic and range of application
The intelligence electronic ball valve of the Model ZAJQ is made up by Taiwan UM and LKR serial intellectual executive bodies and three direct links ball valve L type and T type, it is a kind of rotation that cuts off and regulates the valve, close tightly , the structure is compact, light, it is convenient when the advantage to maintain. In the pipeline automation that is used such corrosivity medium as the gas , liquid , steam , oil ,etc. extensively is controlled.
Two valves of seat sealed three direct links ball valves have structure compactness , aesthetic in appearance and sealing of good performancly. It can realize intermediary that quality flow into to switch over to pipeline. Can enable feeding through or closing in two vertical passways each other too.
There are four valves of seat sealed three direct links ball valves handsome in appearance, the structure compactness is rational , it can realize whom medium flow into switch over, can make three passways feed through each other , can close any passway now , make other two passways feed through , control meeting or distributary of the medium in the pipeline flexibly .
Second, control the main technical indicator of the module
Control the precision: 0.1% 0.1% 3.1% is adjustable.
Accept the control signal: 00mA.DC , 40mA.DC or 1V.DC
The button is chosen: 1, When the input signal is cut off: " cut off " 2 modes (makes , stops , closes ) , choosing 3 against movements , controlling the precision to choose.
The electronic devices are all turned on , close the position and make a reservation automatically standardly completely, it is convenient to be accurate.
Carry on the intellectual step distance and adjust and make a reservation automatically according to the input signal and electronic device position, it is high to suppress the precision of shaking.
Output the position signal of the electronic device : 40mA.DC corresponding electronic device is closed completely , all turn on.
Third, executive body
Type: PSQ , 3810R , YMR angle journey executive body available. The explosion-proof type is selected 3810 series.
Technical parameter and performance : Please consult the corresponding executive body of the company and manual of the valve positioner.
Fourth , the L type main size of ball valve of stainless steel of electronic three direct links , unit mm:
