Ukufakelwa kweevalvu zesango, iivalvu zeglobe kunye neevalvu zokujonga

Ivalvu yesango, eyaziwa ngokuba yi-gate valve, yi-valve esebenzisa isango ukulawula ukuvulwa nokuvalwa. Ilungisa ukuhamba kwemibhobho kwaye ivula kwaye ivale imibhobho ngokutshintsha icandelo elinqamlezileyo lombhobho. Ii-gate valves zisetyenziswa kakhulu kwimibhobho ene-media yolwelo evulekileyo ngokupheleleyo okanye evaliweyo ngokupheleleyo. Ngokubanzi akukho mfuneko yecala lokufaka i-gate valve, kodwa ayinakufakelwa ijonge ezantsi.

Aivalvu yeglobhuyivalvu esebenzisa idiski yevalvu ukulawula ukuvulwa nokuvalwa. Ngokutshintsha umsantsa phakathi kwediski yevalvu kunye nesihlalo sevalvu, oko kukuthi, ukutshintsha ubungakanani becandelo elinqamlezileyo letshaneli, ukuhamba okuphakathi okanye itshaneli ephakathi kuyanqunyulwa. Xa ufaka ivalvu yokumisa, kufuneka kuqwalaselwe indlela ukuhamba kolwelo.
Umgaqo ekufuneka ulandelwe xa kufakwa ivalvu yokumisa kukuba ulwelo olukwipayipi ludlule kumngxuma wevalvu ukusuka ezantsi ukuya phezulu, owaziwa ngokuba yi-"low in and high out", kwaye ukufakwa okungasemva akuvumelekanga.

Ivalvu yokujonga, eyaziwa ngokuba yi-check valve kunye ne-one-way valve, yi-valve evuleka kwaye ivale ngokuzenzekelayo phantsi komahluko woxinzelelo phakathi komphambili nomva we-valve. Umsebenzi wayo kukuvumela i-medium ukuba ihambe kwicala elinye kuphela kwaye ithintele i-medium ukuba ibuyele kwicala elichaseneyo. Ngokwezakhiwo ezahlukeneyo, ii-check valve ziquka ii-lift, i-swing kunye ne-butterfly clamp check valves. Ii-lift check valves zahlulwe zibe ziintlobo ezithe tye nezithe nkqo. Xa ufaka i-check valve, kufuneka uqaphele kwicala lokuhamba kwe-medium kwaye ungayifaki ngasemva.

Ukufakelwa kwevalvu yokunciphisa uxinzelelo

Ivalvu yokunciphisa uxinzelelo yivalvu enciphisa uxinzelelo lokungena ukuya kuxinzelelo olufunekayo lokukhupha ngokulungelelanisa kwaye igcina ngokuzenzekelayo uxinzelelo lokukhupha oluzinzileyo ngokuxhomekeka kumandla esixhobo ngokwaso.

Ngokwembono ye-fluid mechanics, ivalvu yokunciphisa uxinzelelo yinto ethintela ukuxinana enokutshintsha ukumelana kwendawo. Oko kukuthi, ngokutshintsha indawo ethintela ukuxinana, izinga lokuhamba kunye namandla e-kinetic olwelo luyatshintshwa, ngaloo ndlela kuvelise ukulahleka koxinzelelo okwahlukeneyo, ngaloo ndlela kufezekiswa injongo yokunciphisa uxinzelelo. Emva koko, kuxhomekeke ekuhlengahlengisweni kwenkqubo yolawulo kunye nolawulo, amandla entwasahlobo asetyenziselwa ukulinganisela ukuguquguquka koxinzelelo olungasemva kwevalvu, ukuze uxinzelelo olungasemva kwevalvu luhlale luhleli ngaphakathi koluhlu oluthile lwempazamo.

Ukufakelwa kwevalvu yokunciphisa uxinzelelo

1. Iqela levalvu yokunciphisa uxinzelelo elifakwe ngokuthe nkqo lidla ngokufakelwa eludongeni kubude obufanelekileyo ukusuka emhlabeni; iqela levalvu yokunciphisa uxinzelelo elifakwe ngokuthe nkqo lidla ngokufakelwa kwiqonga lokusebenza elisisigxina.

2. Sebenzisa intsimbi emile okwesinyithi ukufaka eludongeni ngaphandle kweevalvu ezimbini zokulawula (ezisetyenziswa rhoqo kwiivalvu zokumisa) ukwenza ibracket. Umbhobho we-bypass nawo unamathele kwibracket kwaye ulinganiswe.

3. Ivalvu yokunciphisa uxinzelelo kufuneka ifakwe ime nkqo kumbhobho othe tye kwaye akufuneki ithambeke. Utolo olusemzimbeni wevalvu kufuneka lukhombe kwicala lokuhamba komoya okuphakathi kwaye alunakufakwa ngasemva.

4. Iivalvu zokumisa kunye neegeyiji zoxinzelelo oluphezulu noluphantsi kufuneka zifakwe kumacala omabini ukuze kubonwe utshintsho loxinzelelo ngaphambi nasemva kwevalvu. Ububanzi bombhobho emva kwevalvu yokunciphisa uxinzelelo kufuneka bube bukhulu nge-2#-3# kunobubanzi bombhobho wokungena phambi kwevalvu, kwaye kufuneka kufakwe umbhobho we-bypass ukuze kube lula ukugcinwa.

5. Umbhobho olinganisa uxinzelelo wevalvu yokunciphisa uxinzelelo lwe-diaphragm kufuneka uqhagamshelwe kumbhobho woxinzelelo oluphantsi. Imibhobho yoxinzelelo oluphantsi kufuneka ixhotyiswe ngeevalvu zokhuseleko ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.

6. Xa isetyenziselwa ukuthomalalisa umphunga, kufuneka kufakwe umbhobho wokukhupha amanzi. Kwiinkqubo zemibhobho ezineemfuno eziphezulu zokucoca, kufuneka kufakwe isihluzo phambi kwevalvu yokunciphisa uxinzelelo.

7. Emva kokuba iqela levalvu yokunciphisa uxinzelelo lifakiwe, ivalvu yokunciphisa uxinzelelo kunye nevalvu yokhuseleko kufuneka ivavanywe uxinzelelo, ihlanjwe kwaye ilungiswe ngokweemfuno zoyilo, kwaye uhlengahlengiso kufuneka luphawulwe.

8. Xa uhlamba ivalvu yokunciphisa uxinzelelo, vala ivalvu yokungena yokunciphisa uxinzelelo uze uvule ivalvu yokucoca ukuze uhlambe.

Ukufakwa kwe-trap

Umsebenzi osisiseko wesithintelo somphunga kukukhupha amanzi aqundiweyo, umoya kunye negesi yekhabhoni-dayoksayidi kwinkqubo yomphunga ngokukhawuleza okukhulu; kwangaxeshanye, inokuthintela ngokuzenzekelayo ukuvuza komphunga kakhulu. Kukho iintlobo ezininzi zezithintelo, nganye inezakhono ezahlukeneyo.

Ngokwemigaqo eyahlukeneyo yokusebenza kweemathiriyeli zomphunga, zingahlulwa zibe ziintlobo ezintathu ezilandelayo:

I-Mechanical: Isebenza ngokweenguqu kwinqanaba le-condensate kwi-trap, kuquka:

Uhlobo lokudada: I-float yi-sphere evaliweyo engenanto.

Uhlobo lokudada oluvuleka phezulu: Idada imile okwebhareli kwaye ivuleka phezulu.

Uhlobo lokudada oluvulayo olujonge ezantsi: I-float imile okwebhareli, imbobo ijonge ezantsi.

Uhlobo lwe-thermostatic: lusebenza ngokweenguqu kubushushu bolwelo, kuquka:

Ishiti ye-Bimetallic: Into ebuthathaka yishiti ye-bimetallic.

Uhlobo loxinzelelo lomphunga: Into ebuthathaka yi-bellows okanye i-cartridge, ezaliswe lulwelo oluguquguqukayo.

Uhlobo lweThermodynamic: Isebenza ngokusekelwe kutshintsho kwiipropati zeThermodynamic zolwelo.

Uhlobo lweDiski: Ngenxa yamazinga ahlukeneyo okuhamba kolwelo negesi phantsi koxinzelelo olufanayo, uxinzelelo olutshintshatshintshayo nolungaguqukiyo lwenziwa ukuze kuqhutywe ivalvu yediski.

Uhlobo lwepulse: Xa i-condensate yamaqondo obushushu ahlukeneyo idlula kwiipleyiti ze-throttle orifice zothotho lweepali ezimbini, uxinzelelo olwahlukeneyo lwenziwa phakathi kweepali ezimbini zeepleyiti ze-throttle orifice, nto leyo eqhuba idiski yevalvu ukuba ihambe.

Ukufakwa kwe-trap

1. Iivalvu zokumisa (iivalvu zokumisa) mazifakwe ngaphambili nangasemva, kwaye kufuneka kufakwe isihluzo phakathi komgibe kunye nevalvu yokumisa yangaphambili ukuthintela ukungcola emanzini abandayo ukuba kungawuvali umgibe.

2. Kufuneka kufakwe umbhobho wokuhlola phakathi komgibe kunye nevalvu yokumisa yangasemva ukujonga ukuba umgibe usebenza kakuhle na. Ukuba kuphuma umphunga omninzi xa uvula umbhobho wokuhlola, umgibe wonakele kwaye udinga ukulungiswa.

3. Injongo yokuseta umbhobho odlulayo kukukhupha amanzi amaninzi aqunyiweyo ngexesha lokuqalisa kunye nokunciphisa umthwalo wokukhupha amanzi kumgibe.

4. Xa ivalvu yokukhupha amanzi isetyenziselwa ukususa i-condensate kwizixhobo zokufudumeza, kufuneka ifakwe kwicandelo elisezantsi lezixhobo zokufudumeza ukuze umbhobho wamanzi we-condensate ubuyele ngokuthe nkqo kwivalvu yokukhupha amanzi ukuthintela ukuqokelelwa kwamanzi kwizixhobo zokufudumeza.

5. Indawo yokufakela kufuneka ibe kufutshane nendawo yokukhupha amanzi kangangoko kunokwenzeka. Ukuba umgama ukude kakhulu, umoya okanye umphunga unokuqokelelwa kumbhobho omde nobhityileyo ophambi komgibe.

6. Xa umbhobho othe tyaba womphunga umde kakhulu, imiba yokukhupha amanzi kufuneka iqwalaselwe.
