Pneumatic Actuator Control Globe Valve
✧ Whakaahuatanga
Pneumatic control globe valve e mohiotia ana ano ko te pneumatic cut-off valve, he ahua o te kaitahuri i roto i te punaha automation, kei roto ko te kaiwhakaari kiriata pneumatic maha-puna, ko te kaiwhakatere piston maanu ranei, me te rei whakahaere, ka whiwhi tohu o te taputapu whakahaere, te whakahaere i te tapahi. , te hono, te whakawhiti ranei o te wai i roto i te pipeline tukanga.Kei a ia nga ahuatanga o te hanganga ngawari, te urupare tairongo me te mahi pono.Ka taea te whakamahi whanui i roto i te hinu, te ahumahi matū, te whakarewa me etahi atu waahanga whakaputa ahumahi.Ko te puna hau o te paera tapatapahi pneumatic e hiahia ana kia tātarihia te hau kōpeke, a ko te reo e rere ana i roto i te tinana takirere kia kore he poke me nga matūriki o te wai me te hau.
Ko te cylinder o te pneumatic globe valve he hua stereotyped, ka taea te wehewehe ki te mahi kotahi me te mahi takirua kia rite ki te ahua o te mahi.Ko te hua mahi kotahi he puna rango tautuhi, kei a ia te mahi tautuhi aunoa o te ngaro o te hau, ara, i te wa e noho ana te piston cylinder (te diaphragm ranei) i raro i te mahi a te puna, ka peia te rakau pana cylinder ki te tuatahi. te tuunga o te rango (te tuunga taketake o te whiu).Karekau he puna hokinga mai o te rango mahi-rua, me te anga whakamua me te hokinga o te pou pana me whakawhirinaki ki te waahi uru me te putanga o te puna hau rango.Ka uru te puna hau ki te ruuma o runga o te piston, ka neke whakararo te pana pana.Ka kuhu te puna hau i roto i te kohao o raro o te piston, ka neke whakarunga te pou pana.Na te mea karekau he puna tautuhi, he nui ake te pana o te puoto mahi-rua i te rango mahi kotahi te diameter, engari kaore he mahi tautuhi aunoa.Ma te mohio, he rereke nga waahi whakauru ka neke te putter ki nga huarahi rereke.I te wa e noho ana te tuunga o te hau ki te rua o muri o te pana pana, ka ahu whakamua te urunga hau ki mua, ka kiia tenei ko te rango pai.Engari, i te wa e noho ana te tuunga o te hau ki te taha kotahi o te toka pana, ka hoki mai te uru o te hau ki muri, ka kiia ko te rango tauhohenga.Pneumatic globe valve no te mea me ngaro te mahi tiaki hau, te nuinga o te waa ka whakamahi i te rango mahi kotahi.

✧ Nga waahanga o te Pneumatic Actuator Control Globe Valve
1. te hanganga o te tinana takirere he nohoanga kotahi, karekau, nohoanga rua (e rua e toru-ara) e toru nga momo, puka hiri he hiri hiri me te pupuhi hiri e rua nga momo, te hua nominal kōeke pēhanga PN10, 16, 40, 64 wha momo, awhe kaliber whakaingoa DN20 ~ 200mm.Te pāmahana wai e tika ana mai i -60 ki te 450 ℃.Ko te taumata leakage ko te akomanga IV, Class VI ranei.Ko te ahuatanga o te rere ko te whakatuwhera tere;
2. Ko te kaitahuri maha-puna me te tikanga whakatikatika e hono ana ki nga pou e toru, ka taea te whakaheke i te teitei katoa mo te 30%, a ka taea te whakaheke i te taumaha mo te 30%;
3. hangaia te tinana takirere rite ki te parau tumu o te rehe wai ki te hongere rere ātete rere iti, whakarea rere reiti piki ake e 30%;
4. te wahi hiri o te pihanga o roto wahi e rua momo o te hiri kiki me te ngohengohe, momo kikī mo te mata carbide sima, momo hiri ngohengohe mo te rauemi ngohengohe, pai te mahi hiri ina kati;
5. taurite takirere internals, whakapai ake i te rerekētanga pēhanga whakaaetia o te vaolo tapahia-atu;
6. Ko te hiri o te pupuhi he hiri katoa i runga i te kakau takirere neke, ka aukati i te pakaru o te reo;
7, te piston actuator, te kaha whakahaere nui, te whakamahi i te rereketanga o te pehanga nui.
✧ Nga Painga o te Pneumatic Actuator Control Globe Valve
I te wa o te whakatuwheratanga me te kati o te puera o te ao maitai, na te mea he iti ake te waku i waenga i te kopae me te mata hiri o te tinana takirere, he iti ake i tera o te paera o te kuaha, he kore e mau.
Ko te whakatuwheratanga, te kati kati ranei o te kakau takirere he poto, a he tino pono te mahi tapahi, a, na te mea ko te huringa o te tauranga nohoanga takirere he rite ki te whiu o te kōpae takirere, he tino pai mo te whakatikatika. o te rerenga rere.Na reira, he tino pai tenei momo takirere mo te tapahi, ki te whakarite ranei me te tarai.
