Iyo pneumatic diaphragm control valve mumufananidzo ndeyemhepo yekudzima mhando. Vamwe vanhu vakabvunza kuti, sei? Kutanga, tarisa kumhepo inopinza kutungamira kweiyo pneumatic firimu, iyo ine mhedzisiro yakanaka. Chechipiri, tarisa kugadzwa kwekugadzika kwe spool, maitiro akanaka. Iyo pneumatic diaphragm chamber yakabatana nemhepo, uye diaphragm inotsikirira pasi chitubu chitanhatu chakafukidzwa nediaphragm, kuitira kusunda vharafu kuti iende pasi. Iyo tsvimbo yevharuvhu yakabatana nepakati yevharuvhu, uye iyo yevhavha core yakaiswa munzira yakanaka, saka iyo mhepo sosi ndiyo vharafu kuenda kunzvimbo yakavharwa. Nokudaro, inonzi gas shut-off valve. Kana gasi rekupa rinokanganiswa nekuda kwekuvaka kana kuora kwepombi yegesi, valve ichagadzirisa zvakare pasi pesimba rekuita rechitubu, uye valve inenge iri munzvimbo yakazaruka zvakakwana. Nzira yekushandisa sei gasi-kuvhara valve? Nzira yekushandisa nayo inofungidzirwa kubva pakuchengetedzwa kwemaonero, iyo ndiyo mamiriro anodiwa ekusarudza gasi kana kuvhara. Semuenzaniso: chimwe chemidziyo yakakosha yebhailer idhiramu rehutsi. Ivhavha inogadzirisa inoshandiswa muhurongwa hwekupa mvura inofanira kunge yakavharwa nemhepo. Sei? Semuenzaniso, kana gasi rinobva kana magetsi akangoerekana avhiringidzwa, choto chichiri kupfuta nechisimba, chinoramba chichipisa mvura mudhiramu remhepo. Kana gasi richishandiswa kuzarura vheji yekudzora uye simba rinokanganiswa, vheji ichavharwa uye dhiramu yemhepo inenge yakaoma (yakaoma inopisa) maminitsi ose pasina mvura inopinda. Izvi zvine ngozi zvikuru. Hazvibviri kutarisana nekukanganisa kwevhavhavha yekudzora munguva pfupi, izvo zvinotungamirira kune ngozi yekuvhara boiler. Nokudaro, kuitira kuti udzivise kupisa kwakaoma kana kunyange kuvhara, valve inofanira kuvharwa negesi. Kunyange zvazvo simba racho rakagurwa uye valve yekudzora iri munzvimbo yakazara yakazaruka, mvura inoramba ichidyiswa mudhiramu, asi haizoiti kuti dhiramu riome. Pachine nguva yekutarisana nekukundikana kwevhavha yekudzora, saka hazvidikanwi kuvhara bhailer zvakananga. Kuburikidza nemienzaniso iri pamusoro, inguva yekuve nekunzwisisa kwekutanga kwekusarudza mhepo pavharuvhu yekudzora uye mhepo inobvisa vharafu!
