1 kushanda musimboti uye basa regedhi vharafu: Gedhi vharafu ndeye blockvhavha rudzi, iyo inowanzoiswa papombi ine dhayamita yakakura kupfuura 100mm kuvhara kana kubatanidza kuyerera kwepakati mupombi. Sezvo disc iplate yegedhi, inowanzonzi gedhi valve. Ivhavha yegedhi ine zvakanakira zvishoma kuchinja simba uye kushoma kuyerera kupikisa. Nekudaro, iyo yekuisa chisimbiso iri nyore kupfeka uye kubuda, iyo yekuvhura sitiroko yakakura, uye kugadzirisa kwakaoma. Ivhavha yegedhi haigoni kushandiswa sevhavha inogadzirisa. Inofanira kunge iri munzvimbo yakazaruka zvachose kana kuti yakavharwa zvakakwana. Nheyo yekushanda ndeye: kana gedhi revhavha rakavharwa, tsinde inofamba ichidzika zvichienderana nekukwirira kwegedhi revhavha yevhavha yekuvhara pamusoro uye chigaro chevhavha chisimbiso chepamusoro, iyo yakatsetseka, yakadzika uye inowirirana. Dzinokwana mumwe nemumwe kudzivirira yepakati kuti isayerera nepakati, uye vanovimba nepamusoro wedge kuti iwedzere chisimbiso chekuita. Kuvharwa kwayo kunofamba kwakatwasuka kudivi repakati. Kune marudzi mazhinji emavharuvhu egedhi, anogona kukamurwa kuita wedge mhando uye parallel mhando. Rudzi rumwe norumwe rwakakamurwa kuita gondohwe rimwe chete negondohwe kaviri. 2 chimiro: Muviri wevharuvhu wegedhi unotora iyo yekuzvisimbisa fomu. Iyo yekubatanidza maitiro evhavhavhavha yevhavha uye muviri wevharuvhu ndeye kushandisa kukwira kumusoro kwepakati mukati mevharuvhu kudzvanya chisimbiso chekuisa chisimbiso kuzadzisa chinangwa chekuisa chisimbiso. High pressure asbestos packing newaya yemhangura inoshandiswa pakuvhara vharafu yegedhi. Chimiro chegedhi revhavha rinonyanya kuumbwa nemuviri wevharuvhu, bhoneti, furemu, dzinde, kuruboshwe uye kurudyi vharafu disc, kurongedza chisimbiso mudziyo, nezvimwewo. Iyo vharafu muviri zvinhu zvakakamurwa kuita kabhoni simbi uye alloy simbi zvinoenderana nekumanikidza uye tembiricha yepiipi yepakati. . Kazhinji yakaiswa muvharuvhu ye superheated steam system, t> 450 ℃, muviri wevharuvhu wakagadzirwa nealloy material, yakadai sevhavha yekupedza bhailer, nezvimwewo. iyo valve body material icarbon steel. Mavharuvhu egedhi anowanzo kuisirwa papombi dzemvura ine utsi neDN ≥ 100mm. Kune marudzi matatu emadhayamita emadhayamita egedhi vharafu muchikamu chekutanga wgz1045 / 17.5-1 bhaira muZhangshan, kureva DN300, dnl25 uye dnl00.
