Pneumatic cuab

Pneumatic cuab

Pneumatic ntxiab yog ib tiam tshiab ntawm chav ntxiab tsim thiab tsim raws li hydrophobicity ntawm thermal fais fab nroj tsuag khoom. Cov khoom lag luam nyob ze rau cov qauv tsim tawm, txo cov dej ntws tawm, cov txheej txheem thib ob throttling, txo kev yaig thiab txhim kho lub neej.

Khoom piav qhia

Lub valve tub ntxhais thiab lub rooj zaum valve yog ua los ntawm cov khoom carbide, kaw sab hauv to<=VI grade, detachable middle cavity seal design, to prevent leakage, easy maintenance, etc. It can also be used in flammable and explosive places, according to the control system or Adjust the signal of the instrument, cut off or open the valve to achieve the requirements for the use of the controlled parameters. Therefore, it is widely used in remote control of industries such as thermal power plants.

Yam ntxwv

Pneumatic chav ntxiab tau muab faib ua qhov zoo thiab qhov tsis zoo, nws lub npe kab kab DN (MM) yog 20~100; nominal siab PN yog 150lb (2.00MPa) thiab lwm qib; gas qhov siab (MPa) 0 14-0. 4; teeb liab ntau yam Pr (KPa) 20-100; 40-200; leakage yuav luag zoo ib yam li 0 to. Cov khoom muaj nyob rau hauv ntau qhov ntau thiab tsawg.

Lub pneumatic ntxiab muaj ib tug tshiab series ntawm pneumatic diaphragm actuators thiab Y-hom ntxiab (Daim duab 1). Y-hom cuab yog ib qho tshwj xeeb-tsim tswj lub cev valve. Ob qhov kawg yog welded thiab haum rau cov kav dej tshwj xeeb.

Lub actuator ntawm pneumatic ntxiab muaj ob hom kev ua: zoo thiab tsis zoo; thaum lub teeb liab siab nce, lub laub pas nrig txuas tawm ntawm lub diaphragm chamber thiab ua raws li hom roj-kaw. Thaum lub teeb liab siab nce, lub laub pas nrig retreats mus rau hauv lub membrane chamber, uas yog hu ua cov tshuaj tiv thaiv, thiab koom tes nrog lub valve los tsim ib hom qhib.

Plus

Thaum lub teeb liab siab ntawm lub pneumatic ntxiab yog nkag mus rau hauv lub membrane chamber, ib tug thrust yog generated nyob rau hauv lub diaphragm, lub caij nplooj ntoos hlav yog compressed, lub laub pas nrig yog tsiv, lub valve qia yog tsav, thiab lub ntws cheeb tsam ntawm lub valve core thiab lub valve. lub rooj zaum valve raug hloov mus txog rau thaum cov tshuaj tiv thaiv quab yuam thiab teeb liab siab ntawm lub caij nplooj ntoos hlav Lub thrust ua ntawm lub diaphragm yog sib npaug kom ua tiav lub hom phiaj ntawm kev hloov kho cov txheej txheem tsis.
