Pfungwa huru dzekusarudzwa kwevharuvhu-TWS Valve

1. Kujekesa chinangwa chevharafumumudziyo kana mudziyo

Sarudza mamiriro ekushanda evhavha: chimiro chechimiro chinoshandiswa, kushanda kwekushanda, kupisa kwekushanda uye nzira yekudzora.

2. Sarudza zvakarurama rudzi rwevhavha

Sarudzo chaiyo yerudzi rwevharuvhu chinhu chinodiwa kuti mugadziri anyatsonzwisisa maitiro ese ekugadzira uye mamiriro ekushanda. Pakusarudza rudzi rwevharuvhu, mugadziri anofanira kutanga abata maitiro ekugadzirisa uye kushanda kwevhavha yega yega.

3. Sarudza kuguma kwekubatanidza kwevhavha

Pakati pezvinongedzo zvakabatanidzwa, flange zvinongedzo, uye welded end connections, maviri ekutanga ndiwo anonyanya kushandiswa. Mavharuvhu ane shinda anonyanya kuve mavharuvhu ane dhayamita rezita pazasi 50mm. Kana iyo dhayamita yakakura kwazvo, kuiswa uye kuiswa chisimbiso kwechikamu chekubatanidza kuchave kwakaoma kwazvo. Mavharuvhu ane shinda ari nyore kuisa nekubvisa, asi anorema uye anodhura kupfuura mavharuvhu akaiswa shinda, saka akakodzera kubatanidzwa kwepombi yemadhayamita akasiyana uye kumanikidza. Welded connections akakodzera mitoro inorema uye akavimbika kupfuura flanged connections. Zvisinei, zvakaoma kuparadzanisa uye kudzorera vheji yakabatanidzwa ne welding, saka kushandiswa kwayo kunogumira kune dzimwe nguva iyo inogona kushanda yakavimbika kwenguva yakareba, kana apo mamiriro ekushandiswa akaoma uye kutonhora kwakakwirira.

4. Kusarudzwa kwezvinhu zvevhavha

Paunosarudza zvinhu zvevhavha shell, zvikamu zvemukati uye chisimbiso chepamusoro, kunze kwekutarisa zvinhu zvemuviri (tembiricha, kumanikidza) uye makemikari zvinhu (corrosiveness) yesvikiro rekushanda, kuchena kwepakati (ine kana isina zvimedu zvakasimba) inofanirawo kubatwa. Pamusoro pezvo, zvinodikanwa kureva kune mirairo yakakodzera yenyika uye dhipatimendi revashandisi. Kwakaringana uye zvine musoro kusarudzwa kwezvinhu zvevharuvhu zvinogona kuwana zvakanyanya hupfumi hwehupenyu hwesevhisi uye kuita kwakanyanya kwevhavha. Iyo yevhavha yemuviri yemhando yekusarudza inoteedzana ndeiyi: cast iron-carbon simbi-stainless simbi, uye yekuisa chisimbiso mhete yemhando yekusarudza kutevedzana ndeye: rubber-copper-alloy simbi-F4.

5. Zvimwe

Mukuwedzera, chiyero chekuyerera uye chiyero chekumanikidza kwemvura inoyerera kuburikidza nevhavha inofanirawo kugadziriswa, uye valve yakakodzera inofanira kusarudzwa uchishandisa data iripo (yakadai sevharafu chigadzirwa catalogs, valve chigadzirwa samples, nezvimwewo).
