Ukugcinwa kwevalve yepneumatic umgaqo wokusebenza kunye nendlela yokusebenza

Ukuthengwa kwevalve ye-pneumatic kuphela kwiinkcukacha ezicacileyo, iindidi, uxinzelelo lokuhlangabezana neemfuno zokuthengwa kwesenzo, zingasetyenziselwa ukulawula ukuhamba komoya, amanzi, umphunga, zonke iintlobo zeendaba ezidliwayo, udaka, ioli, isinyithi solwelo kunye nemidiya ye-radioactive kunye nezinye. iintlobo zolwelo. Ayigqibelelanga kwimeko yoqoqosho lwangoku lwemarike. Ngenxa yokuba abavelisi bevalvu yomoya kukhuphiswano lwemveliso, ngamnye kwivalve yomoya ingcamango yoyilo oludityanisiweyo, ukuveliswa kwezinto ezintsha, kuqulunqwe eyabo imigangatho yeshishini kunye nobuntu bemveliso. Ngoko ke, kubaluleke kakhulu ukubeka phambili iimfuno zobugcisa ngokweenkcukacha xa kuthengwa iivalve ze-pneumatic, kwaye ulungelelanise nabavelisi ukufumana imvumelwano, njengesihlomelo senkontileka yokuthengwa kwe-valve ye-pneumatic.
Ukugcinwa kwevalve yepneumatic:
Ekusebenzeni koomatshini, i-valve ye-pneumatic idlala indima ebalulekileyo, ukusetyenziswa kwayo akufuneki kube nobuchule kakhulu, umgangatho kufuneka uqinisekiswe ngexesha elifanayo, oku kuya kufuna ukugcinwa okufunekayo kwevalve ye-pneumatic, i-valve kunye nesidingo sokugcinwa kunye nesayensi. isimo sengqondo, ukwenza umsebenzi wokulondoloza i-valve ukufezekisa injongo yesiphumo kunye nesicelo.
Amanqaku olondolozo lwemihla ngemihla lwevalve yepneumatic:
I-1, i-valve kufuneka igcinwe kwigumbi elomileyo kunye nelomoya, zombini iziphelo zendlela kufuneka zivaliwe.
I-2, ukugcinwa kwexesha elide le-valve kufuneka kuhlolwe rhoqo, *** ukungcola, kunye nomgangatho wokucubungula ofakwe ngeoli echasene ne-rust.
3. Emva kokufakela, ukuhlolwa rhoqo kufuneka kuqhutywe. Izinto eziphambili zokuhlola zi 1) ukutywinwa kokugqoka kwendawo. (2) Intambo yetrapezoidal inxiba isiqu kunye ne-stem nut. (3) ingaba ukupakishwa kuphelelwe lixesha kwaye akukho mthethweni, ukuba konakele, kufuneka kufakwe endaweni yayo ngexesha. (4) Emva kokugcinwa kwevalve kunye nokudibanisa, uvavanyo lokusebenza lokutywina kufuneka lwenziwe.
Amanqaku olondolozo lwevalve yepneumatic:
1. Injongo yokusetyenziswa kunye nokugcinwa kukwandisa ubomi be-valve kunye nokuqinisekisa ukuthembeka kokuvula nokuvala.
I-2, i-valve stem thread, ehlala ikhuhlana kunye ne-valve stem nut, ukusebenzisa ioli encinci etyheli eyomileyo, i-molybdenum disulfide okanye umgubo wegraphite, ukuthambisa.
3, ungasoloko uvule kwaye uvale ivalve, kodwa kwakhona ujike i-handwheel, yongeza i-lubricant kwintambo ye-stem, ukuthintela ukuluma.
I-4, i-valve yangaphandle, ukongeza umkhono wokukhusela kwi-valve stem, ukukhusela imvula, ikhephu, i-rust rust.
5. Ukuba ivalve ngumatshini oza kususwa, yongeza ioyile yokuthambisa kwibhokisi yegiya ngexesha.
6, soloko ugcina ivalve icocekile.
7. Njalo khangela kwaye ugcine ingqibelelo yamanye amalungu evalve. Ukuba i-nut eqingqiweyo ye-handwheel iyawa, kufuneka ihambelane kwaye ayikwazi ukusetyenziswa, ngaphandle koko iya kugaya isikwere sendawo ephezulu ye-valve stem, ngokuthe ngcembe ilahlekelwa ukuthembeka komdlalo, kwaye ayikwazi ukuqala.
I-8, ungathembeli kwi-valve ukuxhasa ezinye izinto ezinzima, musa ukuma kwi-valve.
I-9, i-valve stem, ngokukodwa inxalenye yentambo, ukusula rhoqo, i-lubricant iye yamdaka ngothuli ukuba ithathelwe indawo entsha, kuba uthuli luqulethe i-debris enzima, kulula ukuyinxiba intambo kunye ne-stem surface, ichaphazela ubomi benkonzo ye-pneumatic single. ivalve yokulawula isihlalo.
Umgaqo wokusebenza kwevalve yepneumatic kunye nendlela yokusebenza
Umgaqo osebenzayo wevalve ye-pneumatic waziswa:
Indawo yokuphuma kwevalve ye-pneumatic yi-actuator yomoya. Imodi yayo yokusebenza kukuqhuba i-valve switch kunye nokulungelelanisa ngoncedo lomoya ocinezelweyo. Ngokohlelo lwemo yolawulo lunokwahlulwa lube luhlobo lokutshintsha kwevalve yepneumatic kunye nodidi olulawulayo lweendidi ezimbini. Uhlobo lwevalve yokutshintsha i-pneumatic iqulethe ii-actuator ze-pneumatic, iivalvu, indlela yokusebenza yesandla, unyango lomthombo womoya wonyango lwe-sanlian, iivalvu ze-solenoid, izitshixo zomda, i-muffler, isinxibelelanisi esikhawulezayo, icompressor yomoya, i-tracheal njl njl. iziqwenga, i-muffler, isinxibelelanisi seplagi ekhawulezayo inokukhethwa ngokukhululekileyo ngokwemeko yesiza. Ivalve yokulawula ipneumatic ibandakanya i-pneumatic actuator, ivalve, indlela yokusebenza ngesandla, ivalve yegesi yombane, indawo yonyango yomthombo womoya, i-muffler, iplagi ekhawulezayo yokudibanisa, umbhobho wokucinezela umoya, njl. zikhethwe ngokukhululekileyo ngokwemiqathango yesiza. Iivalve ze-pneumatic zisetyenziswa ngokubanzi kulawulo oluzenzekelayo lwamanzi, umoya, umphunga, udaka, ioli, isinyithi solwelo kunye nezinye imidiya.
Izilumkiso zokusebenza kwevalve yepneumatic:
Okokuqala, vula ivalve, kufuneka uqaphele:
1. Khangela ukuba i-oyile inako kwisihluzo somoya kunye ne-pressure reducer ifakwe i-refueled (ioli yokuthambisa);
2, khangela ukuba umbhobho ucocekile ukuba kukho inkunkuma, kuyacetyiswa ukuba ufakele isihluzo sombhobho phambi kwevalve.
3. Emva koko qhubeka ulawule imvelaphi
4. Emva kokulungelelanisa uxinzelelo lomthombo womoya, uhlobo lwepiston (0.4-0.7) kg, uhlobo lwefilimu (0.1-0.2) kg
5, kunikezelo lwamandla (uhlobo lokutshintsha luyivoltheji) okanye (uhlobo olulawulayo lwangoku okanye uphawu lombane)
6, kwaye emva koko ulungelelanise okanye uvule ulawulo
Ezimbini, vala ivalve, kufuneka ithathele ingqalelo:
1, cima isignali yolawulo (i-voltage okanye yangoku)
2. Lungisa uxinzelelo lokucoca umoya lube zero
Indlela yokusebenza kwevalvu yomoya:
1. Ukuvula nokuvalwa kwevalve ye-pneumatic kukwindlela yewotshi. Ivalve ye-pneumatic kwinethiwekhi yombhobho wokuvula kunye nokuvala, i-revolution yokuvula kunye nokuvala akufanele ibe yinto eninzi, nokuba i-valve enkulu yobubanzi kufuneka ibe kwi-revolution ye-200-600.
2. Ukuze kuququzelelwe ukuvulwa kunye nokuvalwa kwe-valve ye-pneumatic, umzuzu wokuvula kunye nokuvala kufuneka ube ngaphantsi kwe-240N-m phantsi kweemeko zoxinzelelo lwe-plumber. Ukuvula ivalve yepneumatic kunye nokuphela komsebenzi wokuvala kufuneka kube yi-square tenon, kwaye ubungakanani kufuneka bubekwe emgangathweni, kwaye bujonge phantsi, ukuze abasebenzi bakwazi ukusebenza ngokuthe ngqo emhlabeni. Iivalvu ezineepleyiti zamavili azifanelekanga kuthungelwano lwemibhobho engaphantsi komhlaba.
3. Ukuqinisekisa ukuba ukuvulwa kunye nokuvalwa kwevalve ye-pneumatic ayigqithisi, umgca wesikali wokuvula kunye neqondo lokuvala i-valve ye-pneumatic kufuneka uphoswe ngokumangalisayo kwikhava yebhokisi yebhokisi okanye iqokobhe leplate yokubonisa emva kokutshintsha. yolwalathiso, kwaye kufuneka ijonge emhlabeni. Xa ukulungiswa kokuvula kunye nokuvala ngokuchanekileyo, kufuneka kuvalwe ngeerivets.
4. I-valve ye-pneumatic yokuvula kunye nokusebenza kokuvala kwinethiwekhi yombhobho ayifanelekanga ukusebenza kakuhle. Ukuba indlela yokusebenza kunye nepleyiti yokubonisa yevalve ye-pneumatic ingaphantsi kwe-1.5 yeemitha emhlabeni, indawo yokwandisa intonga ezinzileyo nethembekileyo kufuneka imiselwe, ukwenzela ukuba abasebenzi baqaphele kwaye basebenze phantsi.
