Basic valve setup inouya nekukasira ine muunganidzi valve logo uye pendi yekuzivikanwa

Kugadzika kwevhavha uye kusarudzwa kwemhando yakakodzera (kwete modhi). Mavharuvhu chikamu chakakosha chebasa re process system nyanzvi pakugadzirira PI diagram. Izvo zvirimo zvinotsanangurwa mumutemo uyu zvinotarisisa izvo zvinodikanwa zvekugadzira nekuchengetedza. Paunenge uchiita dhizaini yeinjiniya nekutaura kune iyi mirau, inyanzvi yehurongwa ichaita sarudzo zvichienderana nemamiriro ezvinhu epurojekiti, mamiriro emamiriro ekunze enzvimbo, kubatana kwemafekitari, mashandiro echishandiso, hunhu hwemvura, zvakakosha zvevashandisi nehupfumi, nezvimwe. . Uyu murairo unosumawo maitiro emavharuvhu emaindasitiri uye zvinhu zvinofanirwa kutariswa pakusarudzwa kwemavharuvhu mukugadzirwa kweinjiniya.
1. Izvo zvigadziro zvinoshanda kumakemikari process system majors. Ivhavha yataurwa haisanganisi vharuvhu yekudzivirira, steam trap, sampling valve uye pressure yekudzikisa vharafu, asi inosanganisira inoyerera inomisa orifite plate, bofu plate uye mamwe mapombi mafittings ane mabasa akafanana nevharuvhu, ine vharafu yakachekwa seyakajairwa. zita rezvikamu zvevharuvhu izvi. Basa revhavha yakachekwa rinoshandiswa kucheka mvura kana kuita kuti mvura ichinje mafambiro ekuyerera, maererano nekugadzirwa (kusanganisira kugadzirwa kwakajairwa, kuvhurika uye kuvharika uye yakakosha mamiriro ekushanda), kuchengetedza uye kuchengetedza zvinodiwa uye Zvirongwa, asiwo kufunga nezvehungwaru hwehupfumi.
Kugadzika kwevhavha uye kusarudzwa kwemhando yakakodzera (kwete modhi). Mavharuvhu chikamu chakakosha chebasa re process system nyanzvi pakugadzirira PI diagram. Izvo zvirimo zvinotsanangurwa mumutemo uyu zvinotarisisa izvo zvinodikanwa zvekugadzira nekuchengetedza. Paunenge uchiita dhizaini yeinjiniya nekutaura kune iyi mirau, inyanzvi yehurongwa ichaita sarudzo zvichienderana nemamiriro ezvinhu epurojekiti, mamiriro emamiriro ekunze enzvimbo, kubatana kwemafekitari, mashandiro echishandiso, hunhu hwemvura, zvakakosha zvevashandisi nehupfumi, nezvimwe. .
Uyu murairo wakazara uye wakakwana unosuma kugadzika kwevharuvhu mumakesi akanyorwa uye zvinodikanwa zvemhando dzakasiyana dzemakemikari. Ona iyo yekutanga unit modhi yeinoenderana unit's PI diagiramu.
Mutemo uyu unosumawo maitiro emavharuvhu emaindasitiri uye zvinhu zvinofanirwa kutariswa mukusarudzwa kwemavharuvhu mukugadzira engineering.
2. Kugadzirisa valve
Valvha yakaiswa pamuganhu
Iyo yekugadzira zvinhu uye yakajairika pombi yemidziyo inochekwa pamuganho wechirimwa (kazhinji mukati mechikamu chemuganho wechirimwa)
Kuputika kwevhavha, kunze kwezviitiko zvinotevera:
(1) Exhaust system.
(2) pombi yekuburitsa kana chute yekukurumidzira yekubuda iri kunze kwemuganhu; Kana mavharuvhu achifanira kuiswa muzviitiko zviviri izvi, kuiswa chisimbiso kunodiwawo kuvhura (CSO)
(3) pombi yemidziyo isingakonzere tambo netsaona.
(4) Material chubhu pasina kuyerwa.
FIG. 2.0.1 gadziriro yevharuvhu pamuganhu
Mavharuvhu ari pamuganhu akaiswa munzira dzakawanda sezvinoratidzwa mumufananidzo 2.0.1. Iko (1) inoshanda kune zvakajairika zvinhu
Cheka; Muchiitiko chenjodzi dzekuchengetedza dzakadai semoto kana zvakakosha zvemhando dzetsaona dzinokonzerwa netambo yezvinhu, mahwendefa mapofu anofanirwa kuwedzerwa muFIG. 2.0.1 kudzivirira kubuda kwemukati kwevhavha. (3) uye (5) muFIG. 2.0.1 akakodzera kutsvaira mutsara wekumusoro kana wezasi mushure mekudyisa. Valve A inogona zvakare kushandiswa kuchenesa, kuchenesa, kuona kuvuza, kana mita yekuyedza inogona kuiswa pakati pemavharuvhu maviri akateedzana. (5) muMufananidzo 2.0.1 inoshandiswa apo kushandiswa kwekuchinja kunenge kwakakura uye cheki chevhavha chinoshanda sechekuchekwa pakarepo.
Kugadzika kwevhavha yemidzi
Kana svikiro inoda kutakurwa kune vanopfuura mumwe mushandisi, kuitira kufambisa kuchengetedza kana kuchengetedza simba, anti-kutonhora, mukuwedzera kune midziyo yakasungirirwa.
Pamusoro pevhavha yakachekwa, valve yakachekwa inonzi root valve inoiswa papombi yebazi pedyo nepombi huru. Inowanzo shandiswa mune zvakajairika zvinhu masisitimu (semuutsi, compressed mweya, nitrogen, nezvimwewo). Kurongeka kwakafanana kunodiwa kana chigadziriso chinoshandiswa kune vakawanda vashandisi (semuenzaniso zvinonyungudutsa). Ivhavha inoratidzwa mumufananidzo 2.0.2 ndiyo midzi yevhavha. Mune simba rekuchengetedza antifreeze zvinodiwa, chinhambwe pakati pevharuvhu yemidzi uye mutariri chinofanira kunge chidiki sezvinobvira.
Mufananidzo 2.0.2 Schematic diagram yekuisa midzi yevhavha
Mavharuvhu emidzi anofanirwa kuisirwa pamapaipi ese emapazi emapaipi akajairika mumakemikari chirimwa kudzivirira munhu
Kukuvadzwa kwevharuvhu kunokonzera chirimwa kana chirimwa kudzima.
Steam uye pamusoro pemvura pombi yemvura, kunyangwe kune imwe chirimwa kana imwe mudziyo, kana pombi yebazi ichipfuura imwe urefu, inodawo kuwedzera midzi vharafu kuderedza kufa, kuderedza kushandiswa kwesimba, kudzivirira kutonhora.
Zviviri kana kupfuura zvekubatsira midziyo yemhepo inofanirwa kutariswa zvinoenderana nekukosha kwekugadzirwa kwedavi pombi midzi vharafu.
Iyo midzi yevhavha yepombi yebazi yezvinhu zvakajairika inotarwa nenyanzvi yepombi mukugadzirwa kwepombi yekumisikidza, uye iyo process system nyanzvi inoda kutarisa kuti bazi rakakodzera here. Uye iyo midzi yevhavha inomiririrwa pane yeruzhinji zvinhu PI diagraph (dhiyabhorosi yekugovera).
Double valve
Liquefied petroleum gasi, inopfuta, ine chepfu uye yakakosha zvinwiwa uye zvimwe zvinoparadza zvakanyanya, senge yakasimba acid, caustic soda uye zvine zvakakosha zvinodiwa (senge svikiro rinonhuwa rakakonzera kusvibiswa kwakakomba kune zvakatipoteredza) tangi repakati, uye mutsara pazasi kusvika pazasi. zvimwe zvigadziriso, zvisinei nemimwe midziyo yevharuvhu uye mavharuvhu maviri anofanirwa kuisirwa munhevedzano (mbiri vharafu), Imwe yacho inofanira kunge yakanyatso snug inopesana netangi nozzles. Kana iyo tangi yekuchengetedza yakakura kana kure kure, vharafu iri nani kure kudzora vharafu. Kuti uderedze huwandu hwemavharuvhu, batanidza mapaipi akati wandei kuvhura imwechete sezvakaratidzwa muFIG. 2.0.3–1 kana kushanda kuchibvumira.
Ivhavhavha yevhavha yemudziyo ine zvinyorwa zvataurwa pamusoro apa ichavawo mavharuvhu maviri, sezvinoratidzwa mumufananidzo 2.0.3-1.

2. Kutara nzira
1. Maka zviri mukati
JB/T 106-2004: saizi yezita (DN), kodhi yekumanikidza kana kodhi yekumanikidza yekushanda, mhando yezvinhu kana kodhi, zita remugadziri kana chiratidzo chekutengeserana, nhamba yevira (cast valve) ichaiswa chiratidzo pamusoro pesimba rekumanikidza valve muviri zvinoenderana neGB/ T 12220-1989. Mavharuvhu ane mafambiro ekutungamira anofanirwa kuiswa museve wepakati wekuyerera.
2. Kutara nzira
GB/T 12220-1989: mavharuvhu ane saizi yezita rakakura kupfuura kana kuenzana neDN50 anofanirwa kucherechedzwa nehukuru hwezita (DN), kudzvanywa kwezita (PN), mutsara wezvinhu kana nhamba yekodhi yezvikamu zvakatsikirirwa, zita remugadziri kana chiratidzo, nhamba yevira inonyunguduka. (casting) ichaiswa chiratidzo pamutumbi wevharuvhu. Pamavharuvhu ane saizi yezita isingasviki DN50, mamakisi mana ari pamusoro achamakwa pamutumbi wevharuvhu kana zita rezita sekutsanangurwa kwazvinoitwa nemugadziri. Kana kudzvinyirirwa kwezita rechiratidzo chekukanda chemuviri wevhavha kuchiiswa pazasi pehukuru hwezita, kudzvanywa kwezita hakuzogadziriswe nekodhi "PN".
GB/T 12220-1989 inotsanangura museve wepakati wekuyerera, chisimbiso mhete (pedhi) kodhi chete kana ichinge yatsanangurwa mune imwe chiyero chevharuvhu inofanira kuiswa chiratidzo chevharuvhu muviri uye flange zvichiteerana.
Kana pasina hurongwa hwakakosha muGB/T 12220-1989, zvinhu 7 — 19 patafura iri pamusoro apa zviratidzo zvekushandisa pazvinenge zvichidiwa. Maka pavharuvhu muviri kana nameplate sezvinodiwa.
GB/T 12220-1989 inopa kuti kana saizi yegumbo remaoko yakakura zvakakwana, vhiri reruoko rinofanira kupihwa museve unoratidza kwainovhara vharafu kana kuwedzera "off" mavara.
JB / T 106-2004: muviri wevhavha nekukanda kana kufa kukanda nzira, logo yayo inofanira kukandwa kana kufa yakakandwa pamuviri wevhavha panguva imwe chete. Kana chimiro chemuviri nekufa kwekugadzira nzira, logo yayo mukuwedzera kune muviri panguva imwe chete kufa kwekugadzira kana kufa kukanda, inogona zvakare kucherechedzwa pamuviri ne embossing nzira. Kana chimiro chemuviri wevharuvhu chichigadziriswa nekugadzira, simbi pombi kana simbi plate inotenderedza welding kugadzira, logo yayo mukuwedzera pakuumbwa kweiyo embossing nzira, asi zvakare inogona kushandiswa mune dzimwe nzira dzisingakanganise mashandiro emuviri wevhavha. .
Maka nzvimbo uye maka saizi
