Lub pob valve yog cov khoom siv txhim khu kev qha. Nws yog nquag siv rau cov kav dej, hauv cov cua sov thiab cov pa roj, hauv kev tsim cov roj thiab roj.

Lub pob valve ua haujlwm ruaj ntseg xauv khoom. Sib txawv ntawm qhov yooj yim ntawm kev tsim thiab kev ntseeg siab hauv kev ua haujlwm. Cov txheej txheem no tau hloov tag nrho cov cylindrical thiab conical cranes. Lub hom phiaj tseem ceeb ntawm lub pob valve yog tswj thiab thaiv kev txav ntawm cov pa roj thiab kua nruab nrab thiab tsim kom muaj kev nruj nruj. Qhov no yog ib qho khoom siv tsis tseem ceeb hauv kev ua haujlwm nrog ib puag ncig hnyav.

Lub pob valve kaw yog lub valve nrog lub rooj vag thiab lub ntsej muag kheej kheej. Cov ntsiab lus tseem ceeb ntawm nws cov qauv tsim muaj xws li: lub cev, lub pob nrog lub cylindrical qhov, txav tau spindle, tshem tau kov, ntsaws ruaj ruaj rau spindle, pas nrig. Cov cuab yeej muaj cov qauv tsim muaj zog thiab nyob rau hauv txhua txoj haujlwm tsim ib qho chaw ntws ntawm cov kav dej, nroghermetic kaw ntawm txoj kev.

Lub pob valve muaj nws qhov zoo:

  • siab nruj.
  • Sim me.
  • Ntau pob hnav tsis kam.
  • Simplicity thiab yooj yim ntawm kev tsim.
  • Kev kaw nrawm nrawm (pas, dej).
  • Tus nqi khiav haujlwm tsawg kawg.
  • Txo kev sib tsoo tus nqi.
  • txheej txheem tswj yooj yim.

siv thaj chaw

Valves yog siv rau ntawm qhov loj thiab me me. Qhov chaw nrov tshaj plaws ntawm kev siv yog cov kav dej. Ntawm no nws yog ib qho tseem ceeb heev kom tshem tawm qhov muaj peev xwm ntawm cov pa tawm thaum nws txav mus los ntawm cov kav dej. Lub pob valve muaj qhov nruj nruj thiab siv los ua cov cuab yeej kaw ruaj khov ntawm cov raj xa dej thaum thauj cov pa roj. Nws yog tsim rau cov tes hauj lwm sab hauv tsev, cov tes hauj lwm nrog cov pa roj tsawg, tswj cov roj ntws nrog kev kub siab.

Lub valve muaj peev xwm tswj tau cov dej ntws thiab cov kua dej khov, tshuaj lom neeg tawm tsam thiab chav.

pob valve thiab nws ntau yam

Nyob ntawm cov yam ntxwv engineering, li qub tau muab faib ua ntau yam. Raws li cov qauv tsim, cov cranes tau muab faib ua:

  • ncig-dhau;
  • pob;
  • Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws

  • checkpoints.

Nyob ntawm cov yam ntxwvvalves muab faib ua:

  • shut-off;
  • nrog rau qhov kev hloov kho xauv;
  • Valves nrog lub hom phiaj tshwj xeeb.

Lwm qhov tshwj xeeb rau kev faib cov txheej txheem rau hauv subtypes yog qhov ua haujlwm bandwidth. Ntawm no cov kais dej tau muab faib ua:

  • standard;
  • nplua nuj;
  • tsis muaj bore.

Kev txiav txim siab qhov bandwidth, thaj tsam ntawm ntu ntu ntawm lub qhov hauv lub pob valve yog xam rau thaj tsam hla ntawm lub tog raj kheej.

Lub hom phiaj ntawm lub pob valve yog txiav txim siab los ntawm cov khoom siv ntawm nws cov khoom siv: titanium, steel, polyethylene, cam khwb cia hlau, bronze.

Nyob ntawm kev ua haujlwm, muaj peb hom:

  • Valves rau qhib thiab kaw qhov ntws hauv cov yeeb nkab. Qhov kev xav tau tseem ceeb uas lawv yuav tsum ua raws li yog los xyuas kom meej qhov nruj hauv lub xeev kaw thiab qhov tsawg kawg nkaus ntawm kev tawm tsam hauv txoj haujlwm qhib.
  • Kho pob li qub - siv los hloov tus nqi ntws hauv cov kav dej.
  • lub hom phiaj tshwj xeeb li qub - txhawm rau ua kom muaj kev ua haujlwm zoo nrog qhov chaw nruj heev.

Flanged valve nta

Txhim kho lub kaw-off valve rau cov kav dej, cov khoom tshwj xeeb yog siv. Cov no muaj xws li: welded pob qij txha, flanges, pins thiab couplings. Txhawm rau tiv thaiv cov khoom tshwj xeeb, flanged pob li qub yog siv. Cov khoom siv yog ntsia rau ntawm cov kav dej nrog txoj kab uas hla mus txog 50 mm. Tshwj xeeb sealing gaskets muab lub valve nrog zoo meej nruj.

BFeem ntau, flanged pob valve yog cov cuab yeej zoo tshaj plaws rau kev siv cua sov thiab boiler tes hauj lwm. Nws cov kev sib txuas yog yooj yim nyob rau hauv kev kho, dismantling thiab hloov ntawm lub depressurized cheeb tsam. Qhov no tsis tas yuav vuam.

Actuator hauv flange valve tswj

Mechanical, hluav taws xob thiab pneumatic actuators yog siv los tswj thiab tswj qhov ntws ntawm lub flanged valve. Nyob rau hauv ib tug neeg kho tshuab tsav, muaj cov cuab yeej nyob rau hauv daim ntawv ntawm ib tug handwheel rau manually qhib thiab kaw qhov ntws. Siv cov tsav no thaum yuav tsum tau ua kom compactness.

Pneumatic tsav yog siv rau cua compression. Qhov no yog hom unpretentious tshaj plaws ntawm kev tswj ntawm ib qho kev thauj khoom, txawm tias qhov hnyav tshaj plaws. Flanged pob valve tau nquag siv rau cov kav dej nrog kev kub siab thiab kub kub.

Lub tshuab hluav taws xob muaj peev xwm ua kom muaj kev tswj hwm ntws los ntawm sab hauv cov yeeb nkab. Lub crane raug xaiv raws li qhov kev tsim khoom. Serrated cov ntsiab lus pab qhib thiab kaw cov kwj deg.

Recommendations

Thaum yuav lub pob valve, nws yog ib qho tseem ceeb kom paub tseeb tias qhov tsis zoo ntawm cov dej txias uas lub valve tau xaiv. Nws yuav ua haujlwm ntawm cem quav ntawm dej, thiab tsis yog nws txoj cai. Yog tias qhov kev tswj hwm ntws los kuj xav tau, yuav tsum tau yuav khoom servo-tsav. Rau lub tsev ntiag tug, fittings nrog kev sib txuas thiab kev ua haujlwm siab tsis tshaj 10 bar yog txaus. Rau lub hauv paus cua sov system, sivpob valve nrog lub siab ntawm ntau tshaj 20 bar, thiab coj mus rau hauv tus account lub siab margin. Tej zaum yuav muaj dej rauj.

Ua tib zoo saib xyuas qhov zoo ntawm crane thiab tsis txhob yuav cov khoom tsis zoo. Cov khoom lag luam ntawm cov chaw tsim khoom hauv Suav teb tsis yog qhov xav tau zoo, vim tias kev tsim khoom siv cov khoom tawg yooj yim, corrosive, uas txo qis lub neej ntawm lub valve.
