Yakagadzirwavharafus inofanirwa kuita bvunzo dzakasiyana dzekuita, iyo inonyanya kukosha ndeyekumanikidza kuyedzwa. Kudzvanya bvunzo ndeyekuyedza kana iyo yekumanikidza kukosha iyo valve inogona kumira inosangana nezvinodiwa zvemitemo yekugadzira.MuTWS, iyonyoro akagara butterfly vharafu, inofanirwa kutakurwa yakakwira chigaro chekumanikidza bvunzo. Kumanikidzwa kunotsanangurwa mu 1.5 nguva dzePN ichashandiswa kumvura yekuedza.
Mazwi akakosha:Pressure Testing;Soft Seated Butterfly Valve; Pressure Seat Tightness Test
Kazhinji, muedzo wekumanikidza wemavharuvhuinofanirwa kutevedzera zvinotevera misimboti nedziviriro:
(1) Kazhinji, iyovharafuhaisi pasi pekuedzwa kwesimba, asivharafumuviri uye bhoneti mushure mekugadzirisa kana iyovharafumuviri uye bhoneti ine ngura kukuvara kunofanirwa kuongororwa simba. Yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,kumanikidzwa kwayo nguva dzose,kudzokorodza kudzvanya uye mamwe maedzo anozoenderana nemadimikira emirairo yawo nemirau yakakodzera.
(2) Iyo simba uye tightness bvunzo inofanira kuitwa pamberi pevharafuyakaiswa. 20% yevhavha yepasi-yakadzika-inotariswa, uye 100% yavo inofanira kuongororwa kana isina kukodzera; 100% yepakati uye yakakwirira-yekumanikidza mavharuvhu inofanira kuongororwa.
(3) Munguva yekuedzwa, nzvimbo yekuisa yevharafuinofanira kunge iri munzira iyo kuongorora kuri nyore.
(4) Nokutimavharuvhumuchimiro chekubatanidzwa kwewelded, kana iyo bofu plate yekumanikidza bvunzo isingagone kushandiswa, iyo conical chisimbiso kana O-ring chisimbiso chinogona kushandiswa pakumanikidza bvunzo. (5) Usabvisa mhepo yevhavha zvakanyanya sezvinobvira panguva ye hydraulic test.
(6) Kumanikidzwa kunofanira kuwedzera zvishoma nezvishoma panguva yekuedzwa, uye kupinza uye kamwe-kamwe kudzvinyirira hakubvumirwi.
(7) Nguva yekuyedzwa kwesimba uye yekuisa chisimbiso mhando bvunzo inowanzoita maminetsi maviri-3, uye yakakosha uye yakakosha mavharuvhu anofanirwa kugara kwemaminitsi mashanu. Nguva yekuyedza yemavharuvhu madiki-dhayamita inogona kupfupika, uye nguva yekuyedza yemavharuvhu makuru-dhayamita inogona kuenzana kureba. Panguva yekuedzwa, kana pasina mubvunzo, nguva yekuedza inogona kuwedzerwa. Panguva yekuyedzwa kwesimba, kudikitira kana kubuda kweiyovharafumuviri nebhoneti hazvibvumidzwe. Iyo yekuisa chisimbiso bvunzo inongoitwa kamwe chete kune generalmavharuvhu, uye kaviri kune mavharuvhu ekuchengetedza, high-pressuremavharuvhunezvimwe zvakakoshamavharuvhu. Munguva yekuedzwa, kuderera kuduku kunobvumirwa kune zvisingakoshi mavharuvhu ane kuderera kwakadzika uye dhayamita yakakura uye mavharuvhu ane mitemo yekubvumira kubuda; nekuda kwezvinodiwa zvakasiyana zvemavharuvhu akajairika, mavharuvhu emagetsi emagetsi, mavharuvhu emugungwa uye mamwe mavharuvhu, zvinodiwa zvekudonha zvinofanirwa kunge zvinotevera: Ita zvinoenderana nemirairo yakakodzera.
(8) Iyo throttle valve haisi pasi pekuedzwa kwekusimba kwechikamu chekuvhara, asi kuedza kwesimba uye kuoma kwekuedza kwekutakura uye gasket kunofanira kuitwa. (9) Panguva yekuedzwa kwekumanikidza, simba rekuvhara revhavha rinongobvumirwa kuvharwa nemunhu mumwe chete simba remuviri; hazvibvumirwi kushandisa simba nemidziyo yakadai semarevheti (kunze kwe torque wrench). Kana iyo dhayamita yevhiri remaoko yakakura kupfuura kana yakaenzana ne320mm, vanhu vaviri vanobvumirwa kushanda pamwechete. kuvhara.
(10) Kune mavharuvhu ane chisimbiso chepamusoro, kurongedza kunofanira kutorwa kunze kwekuyedza kusimba. Mushure mekunge chisimbiso chepamusoro chavharwa, tarisa kuti pane kubuda. Paunenge uchishandisa gasi seyedzo, tarisa nemvura mubhokisi rekuisa. Paunenge uchiita kurongedza kusimba bvunzo, chisimbiso chepamusoro hachibvumirwe kuve munzvimbo yakaoma.
(11) Kune chero vharafu ine mudziyo wekutyaira, kana uchiyedza kusimba kwayo, mudziyo wekutyaira unofanirwa kushandiswa kuvhara vharafu uye kuita bvunzo yekusimba. Kune mudziyo unofambiswa nemaoko, bvunzo yekuisa chisimbiso yevhavha yakavharwa nemaoko ichaitwa zvakare.
(12) Mushure mekuedzwa kwesimba uye kusimba bvunzo, iyo bypass valve yakaiswa pavhavha huru ichaongororwa simba uye kusimba pavhavha huru; apo chikamu chekuvhara chevhavha huru chikavhurwa, chichavhurwawo saizvozvo.
(13) Panguva yekuyedzwa kwesimba kwemavharuvhu esimbi yakakandwa, dzvanya muviri wevharuvhu uye chivharo chevharuvhu nebhero remhangura kuti utarise kuvuza.
(14) Kana vheji ichiedzwa, kunze kwevhavhavha inobvumira nzvimbo yekuvhara kuti iwane mafuta, mamwe mavharuvhu haabvumirwi kuedza nzvimbo yekuvhara nemafuta.
(15) Munguva yekumanikidzwa kwevhavhavhavha, simba rekumanikidza rebhofu riri pavhavha harifaniri kunge rakanyanya kukura, kuitira kuti udzivise deformation yevhavha uye kukanganisa maitiro ekuedza (kana simbi yakakandwa yakamanikidzwa zvakasimba. , ichakuvadzwa).
(16) Mushure mokunge muedzo wekumanikidzika wevhavha wapera, mvura yakaunganidzwa muvhavha inofanira kubviswa munguva uye kuchenesa, uye rekodhi rekodhi rinofanirawo kuitwa.
In TWS valve, maererano nechigadzirwa chedu chikuru, iyo yakapfava yakagara butterfly vharafu, inofanirwa kutakurwa yakakwira yekumanikidza chigaro chetightness bvunzo. Uye iyo yekuyedza svikiro imvura kana gasi, uye tembiricha yebvunzo yepakati iri pakati pe5℃~40℃.
Uye kunotevera kuyedzwa kusimba kwegoko uye kuita kwevharuvhu.
Chinangwa chayo ndechekuti bvunzo ichasimbisa kudonhedza kwegomba kunosanganisira kushandiswa kwechisimbiso kunopesana nemukati wekumanikidza.
Munguva yekuyedza maitiro, isu tinofanirwa kuona kuti bvunzo fluid ichave mvura.
Uye dhisiki yevhavha ichave iri munzvimbo yakazaruka zvishoma.Kuguma kwekubatanidza kwevhavha kuchavharwa uye mazamu ose akazara nemvura yekuedza. Kumanikidzwa kunotsanangurwa mu 1.5 nguva dzePN ichashandiswa kumvura yekuedza.
