Cov yam ntxwv zoo
Electric pob valve
1. Lub qhov rooj xauv yog muab rau ntawm qhov chaw qhib thiab kaw tag nrho ntawm lub valve kom tiv thaiv kev ua haujlwm tsis zoo los ntawm cov neeg ua haujlwm tsis yog.
2. Ib kauj ruam yog muab rau hauv qab ntawm lub qia valve los tiv thaiv lub qia ntawm lub valve los ntawm dislodged vim qhov txawv txav ntawm lub siab sab hauv ntawm lub valve.
3. Lub nplhaib hluav taws kub-resistant sealing yog muab nruab nrab ntawm lub pob thiab lub rooj zaum valve, thiab lub rooj zaum valve tseem muaj qhov sib khi zoo tom qab raug hlawv.
4. Kev hloov ceev ceev, hloov tau yooj yim qhib thiab kaw, lub neej ua haujlwm ntev, muaj kev nyab xeeb thiab txhim khu kev qha.
5. Lub pob hluav taws xob hluav taws xob tuaj yeem tswj tau hauv nruab nrab ntawm qhov kev ncua deb thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev tswj hwm lub computer.
Lub pob hluav taws xob pob valve actuator yog ib qho tseem ceeb ntawm kev tsav tsheb tswj cov cuab yeej rau kev paub txog cov kev tswj hwm, kev tswj tsis siv neeg thiab cov chaw taws teeb tswj ntawm lub pob hluav taws xob. Nws cov txheej txheem txav yog tswj los ntawm kev mob stroke, torque, thiab lwm yam. Txij li thaum cov yam ntxwv ua haujlwm thiab kev siv tus nqi ntawm lub pob hluav taws xob valve actuator nyob ntawm hom thiab cov yam ntxwv ntawm lub pob valve, kev xaiv kom raug ntawm lub pob valve actuator yog qhov tseem ceeb los tiv thaiv overload.
Tus actuator tso zis torque yog qhov tseem ceeb tshaj plaws rau kev xaiv hluav taws xob actuators. Lub actuator tso zis torque yuav tsum yog 1.2 ~ 1.5 lub sij hawm lub siab tshaj plaws kev khiav hauj lwm torque ntawm lub pob valve xaiv. Thib ob, raws li kev siv sib txawv ntawm lub pob valve, qhov tsim nyog qhib thiab kaw nrawm yuav tsum raug xaiv los tiv thaiv lub pob valve actuator los ntawm kev qhib thiab kaw nrawm dhau los ua rau dej rauj.
Hluav taws xob lub pob valve actuators muaj cov kev cai tshwj xeeb, uas yog, lawv yuav tsum muaj peev xwm txwv torque (axial force) thiab tig lub kaum sab xis. Thaum cov kev qhia tshwj xeeb ntawm cov cuab yeej hluav taws xob tau txiav txim siab, nws qhov kev tswj torque kuj tau txiav txim siab. Feem ntau, lub cev muaj zog yuav tsis overloaded thaum khiav hauv lub sij hawm predetermined. Txawm li cas los xij, overload tuaj yeem tshwm sim hauv cov xwm txheej hauv qab no: Ua ntej, lub zog hluav taws xob qis qis, thiab qhov xav tau torque tsis tuaj yeem tau, ua rau lub cev muaj zog nres; Thib ob, lub zog torque txwv tsis raug hloov kho kom muaj zog ntau dua qhov nres torque, ua rau lub zog txuas ntxiv, ua rau lub cev muaj zog nres; thib peb, sib quas ntus siv, lub tshav kub generated accumulates, tshaj qhov tso cai kub nce nqi ntawm lub cev muaj zog; thib plaub, lub torque txwv mechanism Circuit Court tsis ua hauj lwm rau qee yam, ua rau lub torque loj heev; fifth, qhov kub thiab txias ambient siab dhau lawm, uas kuj txo cov thermal muaj peev xwm ntawm lub cev muaj zog.
