Mapoinzi akakosha ekusarudza valve
1 Bvuruvhu rakajeka mumidziyo kana kushandisa mudziyo
Sarudza mamiriro ekushanda evhavha: chimiro chepakati inoshandiswa, kushanda kwekushanda, kupisa kwekushanda uye maitiro ekugadzirisa maitiro.
Sarudza rudzi rwakakodzera rwevhavha
Sarudzo chaiyo yerudzi rwevharuvhu yakavakirwa pamugadziri weiyo yese nzira yekugadzira, kubata kwakazara kwemamiriro ekushanda sechinhu chinodiwa, mukusarudzwa kwerudzi rwevharuvhu, mugadziri anofanira kutanga aziva maitiro ekugadzirisa uye kushanda kwevhavha yega yega.
Sarudza kuguma kwekubatanidza kwevhavha
In threaded connection, flange connection, welding end connection, maviri ekutanga marudzi akajairika. Mavharuvhu ane thread anonyanya kuve mavharuvhu ane dhayamita yezita pazasi 50mm. Kana hupamhi hwehupamhi hwakanyanya, kuiswa uye kuiswa chisimbiso chekubatanidza kwakaoma zvikuru.
Mavharuvhu ane shinda ari nyore kuisa nekubvisa, asi iwo akakura uye anodhura kupfuura mavharuvhu ane threaded, saka akakodzera kubatanidzwa kwepombi ehukuru hwakasiyana uye kumanikidza.
Iyo welded yekubatanidza inovimbika kupfuura iyo flanged yekubatanidza, iyo yakakodzera kurodha mamiriro. Asi iyo welded valve disassembly uye reinstallation yakanyanya kuoma, saka kushandiswa kwayo kunowanzo mukushanda kwakavimbika kwenguva refu, kana kushandiswa kwemamiriro ekurodha, kupisa kwakanyanya.
4. Kusarudzwa kwezvinhu zvevhavha
Sarudzo yevharuvhu goko, yemukati memukati uye yekuisa chisimbiso pamusoro pezvinhu, mukuwedzera pakufunga nezve iyo yenyama yepakati yekushanda (tembiricha, kudzvanywa) uye makemikari zvivakwa (corrosion), inofanirwawo kugona dhigirii rehutsanana hwemidhiya (ine kana isina zvimedu zvakasimba. ), mukuwedzera, asi zvakare tarisa kune zvinoenderana nezvinodiwa zvehurumende uye kushandiswa kwemadhipatimendi.
Yakarurama uye inonzwisisika sarudzo yevhavha zvinhu inogona kuwana yakanakisa yehupfumi sevhisi hupenyu uye kuita zvirinani kwevhavha. Valve body material selection order: cast iron - carbon steel - Stainless steel, yekuisa chisimbiso mhete yekusarudza zvinhu: rabha - mhangura - alloy simbi -F4.
Zvimwe zvishanu
Muchiwedzera, THE FLOW RATE AND PRESSURE LEVEL YEFLUID IRI KUPIRIRA NOKUBUDZERA INOFANIRA KUTUNGAMIRIRA, UYE IVA yakakodzera valve inofanira kusarudzwa uchishandisa ruzivo rwuripo (semuenzaniso, valve product catalog, valve product sample, etc.).
Tsanangudzo yeakajairika valve mhando kusarudzwa
Tsanangudzo yegedhi revhavha yemhando yekusarudza
Kazhinji, kukoshesa kunofanira kupiwa mavhavha emagedhi. Gedhi vharafu mukuwedzera kune akakodzera chiutsi, oiri uye mamwe midhiya, asi zvakare inoshanda kune ine granular yakasimba uye viscosity yepakati, uye inokodzera vent uye yakaderera vacuum system mavharuvhu. Kune zvepakati nezvidimbu zvakasimba, muviri wevharuvhu wegedhi uchapihwa imwe kana maviri maburi ekugezesa. Kune yakaderera tembiricha yepakati, yakaderera tembiricha gedhi vharafu inofanira kusarudzwa.
2. Tsanangudzo yekucheka-kubvisa valve kusarudzwa
Globe vharafu inokodzera fluid kuramba zvinodiwa hazvisi kuomarara papombi, ndiko kuti, kurasikirwa kwekumanikidza hakutariswe, uye tembiricha yepamusoro, yakanyanya kumanikidza yepakati pombi kana mudziyo, wakakodzera DN Dikivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava,zvakadai sevharuvhu yetsono,sampling valve, pressure gauge valve, etc.;
Ivhavha yevhu ine kuyerera kwekuyerera kana kudzvinyirira mutemo, asi kugadzirisa kurongeka hakuna kukwirira, uye dhayamita yepombi ishoma, zvakakodzera kusarudza globe valve kana throttle valve;
Pamhepo ine muchetura zvakanyanya, zvakakodzera kusarudza mabhero akavharirwa globe valve; Asi vharuvhu yepasi haifanirwe kushandiswa pakati nepakati ine viscosity yakakura uye yepakati ine zvimedu zviri nyore kunaya, uye haifanirwe kushandiswa sevharuvhu yemhepo uye vharafu yepasi vacuum system.
3. Tsanangudzo yekusarudza kwevhavha yebhora
Bhora vharafu inokodzera yakaderera tembiricha, high pressure, viscosity yepakati. Mazhinji bhora mavharuvhu anogona kushandiswa pakati neyakaturikwa yakasimba particles, maererano nekuisa chisimbiso zvinhu zvinodiwa zvinogonawo kushandiswa muupfu uye granular media;
Iyo yese-channel bhora vharafu haina kukodzera kuyerera kuyerera, asi yakakodzera kukurumidza kuvhura nekuvhara zviitiko, zviri nyore kuwana emergency kucheka; Kazhinji mukuita chisimbiso chakasimba, kupfeka, shrinkage chiteshi, kukurumidza kuvhura nekuvhara chiito, high pressure cutoff (yakanyanya kudzvanywa musiyano), yakaderera ruzha, gasification chiitiko, diki yekushandisa torque, kuramba kwemvura, kushandiswa kwemavharuvhu ebhora kunokurudzirwa.
Bharuvha yebhora inokodzera chimiro chechiedza, yakaderera kudzvinyirirwa kubviswa, corrosive media; Bhora vharafu kana yakaderera tembiricha, cryogenic svikiro cheyakanaka vharafu, yakaderera tembiricha svikiro pombi hurongwa uye mudziyo, inofanira kusarudzwa ine yakaderera tembiricha bhora vharafu vharafu;
Iyo inoyangarara bhora vharafu chigaro chechigaro chinofanira kutora mutoro webhora uye yepakati yekushanda, hombe caliber bhora vharafu mukushanda inoda simba rakakura, DN≥
200mm bhora vharafu inofanira kusarudza worm gear transmission fomu; Fixed ball valve inokodzera dhayamita yakakura uye nguva dzekumanikidza; Pamusoro pezvo, vharafu yebhora inoshandiswa kugadzira zvinhu zvine muchetura zvakanyanya, pombi inobvira midhiya, inofanirwa kuve nemoto, anti-static chimiro.
4. Tsanangudzo yekusarudza throttle valve
Throttle valve inokodzera yakaderera tembiricha yepakati, yakakwirira yekumanikidza nguva, yakakodzera kudikanwa kwekugadzirisa kuyerera uye kumanikidza zvikamu, kwete viscosity uye ine yakasimba particles yepakati, haifanirwe kushandiswa sevhavhavhavhavha.
Tsanangudzo yekusarudzwa kwemhando yevharuvhu
Plug valve inokodzera kukurumidza kuvhura uye kuvhara nguva, kazhinji haina kukodzera kupfuti uye yakakwirira tembiricha yepakati, kune yakaderera tembiricha, yakakwirira viscosity yepakati, zvakare yakakodzera yepakati neyakamiswa zvimedu.
Tsanangudzo yekusarudza rudzi rwe butterfly valve
Butterfly vharafu inokodzera dhayamita hombe (senge DN> 600mm) uye ipfupi chimiro chinodiwa kureba, uye kudiwa kwekuyerera kwemutemo uye nekukurumidza kuvhura nekuvhara zvinodiwa, zvinowanzoshandiswa pakupisa ≤.
80 ℃, kumanikidza ≤1.0MPa mvura, mafuta nemhepo yakamanikidzwa uye mamwe midhiya; Nekuda kwevhavhavhavhavhavhavha yegedhi, vharafu yevharuvhu yekurasikirwa yakakura, saka butterfly vharafu inokodzera kurasikirwa kwekumanikidza zvinodiwa haina kuomarara mupombi system.
Tsanangudzo yekusarudza vharafu cheki
Cheki vharafu inowanzokodzera midhiya yakachena, haifanirwe kushandiswa mukati mepakati ine zvimedu zvakasimba uye viscosity hombe. Kana ≤40mm, zvinokurudzirwa kushandisa lift check valve (* inobvumirwa kuiswa pahorizontal pipeline); Kana DN = 50 ~ 400mm, zvakakodzera kushandisa swing type lift cheki vharuvhu (mupombi yakatwasuka uye yakatwasuka inogona kuiswa, seyakaiswa mupombi yakatwasuka, kuyerera kwepakati kubva pasi kumusoro);
Kana DN≥450mm, buffer mhando cheki vharuvhu inofanira kushandiswa; Apo DN = 100 ~ 400mm inogonawo kusarudza iyo clamp type check valve; Swing cheki vharafu inogona kugadzirwa yakanyanya kumanikidza kushanda, PN inogona kusvika 42MPa, zvinoenderana negoko uye chisimbiso zvinhu zvinogona kuiswa kune chero yekushanda svikiro uye chero yekushanda tembiricha renji.
Iyo yepakati imvura, chiutsi, gasi, corrosive medium, mafuta, mushonga, etc. Kushanda tembiricha yepakati iri pakati -196 ℃ ne800℃.
Tsanangudzo yekusarudza vharafu diaphragm
Diaphragm vharafu inokodzera kushanda tembiricha isingasviki 200 ℃, kumanikidza isingasviki 1.0MPa mafuta, mvura, asidhi yepakati nepakati ine yakaturikwa nyaya, isingakodzeri organic solvents uye yakasimba oxidant medium;
Abrasive granular medium inofanira kusarudza weir diaphragm valve, sarudza weir diaphragm vharafu kureva kuyerera kwayo maitiro tafura; Viscous fluid, simende slurry uye precipitating medium inofanira kusarudzwa yakananga kuburikidza ne diaphragm valve; Kunze kwekunge zvatsanangurwa neimwe nzira, iyo diaphragm valve haifanirwe kushandiswa pamitsetse yevacuum uye vacuum midziyo.
