Mavharuvhu egedhi:
Varuvhu (gedhi) zvinoreva vharafu ine zvikamu zvekuvharira (gedhi ndiro) inofamba ichienda kwakatwasuka ichitevedza akiso yegwara. Inonyanya kushandiswa sechidimbu chekucheka pane pombi, kureva kuti, yakazaruka zvakakwana kana yakavharwa zvakakwana. Kazhinji, mavharuvhu emagedhi haagoni kushandiswa kugadzirisa kuyerera. Inogona kuiswa kune yakaderera tembiricha kumanikidza inogona zvakare kuiswa kune yakakwira tembiricha uye yakakwira kudzvanywa, uye zvinoenderana nezvinhu zvakasiyana zvevhavha. Asi mavharuvhu emagedhi haawanzo shandiswa kutakura madhaka uye mamwe midhiya mupombi.
Zvakanakira: ① kupikisa kwemvura kudiki; (2) Torque diki inodiwa pakuvhura nekuvhara; (3) Inogona kushandiswa muloop network apo iyo yepakati inoyerera mumativi maviri, kureva kuti, kuyerera kwepakati hakuna kudziviswa; 4 (5) Chimiro chechimiro chiri nyore, uye tekinoroji yekugadzira iri nani; ⑥ Kureba kwechimiro kupfupi.
Zvakaipa: (1) saizi yese uye kureba kwekuvhura kwakakura, uye inodiwa yekuisa nzvimbo yakakurawo; (2) Mukuita kwekuvhura nekuvhara, chisimbiso pamusoro pemunhu chisimbiso chehukama, kurasikirwa kwekukwevera kwakakura, kunyangwe pakupisa kwakanyanya kuri nyore kukonzera chafing chiitiko; (3) General gedhi mavharuvhu ane maviri ekuvhara mavhavha, ayo anowedzera mamwe matambudziko ekugadzirisa, kugaya uye kugadzirisa; Nguva refu yekuvhura nekuvhara.

Butterfly:
Shavishavi vharuvhu imhando yevharuvhu inoshandiswa kuvhura, kuvhara nekugadzirisa chiteshi chemvura nekutenderedza dhisiki rinovhura nekuvhara zvikamu zve90 °.
Zvakanakira: (1) Chimiro chakapfava, vhoriyamu diki, uremu huremu, kushandisa, usashandise mavharuvhu makuru; (2) Kukurumidza kuvhura nekuvhara, kushoma kuyerera kwekudzivirira; ③ Inogona kushandiswa kwepakati neyakaturikwa yakasimba zvimedu, zvinoenderana nesimba rekuisa chisimbiso chepamusoro chinogona zvakare kushandiswa kune hupfu uye granular medium. Inogona kushandiswa bidirectional kuvhura uye kuvhara uye kugadzirisa kwemhepo uye guruva rekubvisa pombi. Inogona kushandiswa gasi pombi uye nzira yemvura yesimbi, indasitiri yemwenje, simba remagetsi, petrochemical system, nezvimwe.
Zvakaipa: ① Iyo yekuyerera inogadzirisa huwandu haina kukura, kana yakavhurwa kusvika 30%, kuyerera kuchapinda kupfuura 95%. Nekuda kwemaitiro uye zvisimbiso zvevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,haikodzeri tembiricha uye high pressure piping system. General kushanda tembiricha pazasi 300 ℃, PN40 pazasi. ③ Kuiswa chisimbiso kwakashata kana kuchienzaniswa nemavharuvhu ebhora uye mavharuvhu eglobe, saka inoshandiswa kunzvimbo dzinodiwa zvekuisa chisimbiso zvisiri zvakanyanya.

Ball valve:
Yakagadzirwa kubva pavharuvhu yeplug, chikamu chayo chekuvhura nekuvhara ibhora, uchishandisa bhora kutenderedza 90 madhigirii kutenderedza axis yehunde yevharuvhu kuzadzisa chinangwa chekuvhura nekuvhara. Bharavhavha mupombi rinonyanya kushandiswa kucheka, kugovera uye kushandura mafambiro epakati kuyerera, akagadzirirwa kuva V-yakaita seV yekuvhura bhora vharafu zvakare ine yakanaka kuyerera kwekutonga basa.
Advantages: (1) ine yakaderera kuyerera kuramba (chaizvoizvo 0); (2) Nekuti haizobatiki pabasa (kana pasina mafuta ekuzora), inogona kushandiswa zvakavimbika kune inoora midhiya uye yakaderera yekubikira mvura; ③ Mukumanikidza kwakakura uye tembiricha renji, inogona kuwana chisimbiso chakazara; (4) Inogona kuona nekukurumidza kuvhura nekuvhara, uye nguva yekuvhura nekuvhara yezvimwe zvimiro i 0.05-0.1s, kuitira kuti ive nechokwadi chekuti inogona kushandiswa mune otomatiki system yemubhedha wekuyedza. Kurumidza kuvhura uye kuvhara valve, kushanda pasina kukanganisa. (5) Spherical kuvhara zvikamu zvinogona kuiswa otomatiki panzvimbo yemuganhu; Iyo yekushanda inoshandiswa yakavimbika kumativi ose echisimbiso; ⑦ munzvimbo yakazaruka uye yakavharwa zvakazara, bhora uye chigaro chisimbiso chepamusoro uye pakati pepakati, saka kumhanya kwakanyanya kuburikidza nepakati pevharuvhu hakuzokonzerese kuvharika kwepasi; Compact dhizaini, huremu huremu, inogona kutorwa seyakanyanya kunzwisisika vharafu chimiro cheyakadzika tembiricha yepakati system; ⑨ Muviri symmetry, kunyanya welded chimiro chemuviri, inogona kumira kushushikana kubva papombi; ⑩ Zvikamu zvekuvhara zvinogona kumirisana nekudzvanywa kwakasiyana panguva yekuvhara. Zvakakwana wakasungwa vharafu bhora vharafu, anogona kuvigwa zvakananga muvhu, kuitira kuti vharafu mukati havazoparadzwi, zvishoma yakakwirira basa upenyu anosvika makore 30, ndiyo yakanakira vharafu kuti oiri uye gasi mapaipi.
Zvakashata: (1) Nokuti iyo huru yevhavha yechigaro chekuvhara mhete yemhete ndeye PTFE, inert kune inenge yese makemikari zvinhu, uye ine diki coefficient of friction, kushanda kwakadzikama, kusiri nyore kuchembera, tembiricha yakasiyana-siyana uye yakanakisa yekuisa chisimbiso. . Nekudaro, izvo zvemuviri zve teflon, kusanganisira yakakwira coefficient yekuwedzera, sensitivity kune inotonhora kuyerera, uye yakashata yekupisa conductivity, inoda kuti chigaro chigadziriswe chakatenderedza maitiro aya. Saka, kana iyo yekuisa chisimbiso ichiomesa, kuvimbika kwechisimbiso kunokanganiswa. Uyezve, kupisa kwekushisa kwePTFE kwakaderera, uye kunogona kushandiswa chete pasi pemamiriro asingasviki 180 ℃. Pamusoro pe tembiricha iyi, chisimbiso chinozochembera. Panyaya yekushandiswa kwenguva refu, kazhinji haishandiswe pa120 ℃. (2) Kubata kwayo kwekutonga kwakaipa kupfuura iyo yevhavha yepasi, kunyanya iyo pneumatic valve (kana yemagetsi valve).

Globe mavharuvhu:
Inoreva vharafu apo nhengo yekuvhara (disc) inofamba ichitevedza mutsetse wepakati pechigaro. Maererano nemhando iyi yekufamba kwevhavha disc, kuchinja kwevhavha yechigaro chevhavha inofananidzwa nevhavha disc stroke. Nekuti tsinde yekuvhura kana kuvharika kwerudzi urwu rwevharuvhu ipfupi, uye ine yakavimbika yekucheka basa, uye nekuti shanduko yechigaro chevharuvhu kuburikidza nechiteshi uye kurova kwe disc kunoenderana zvakananga nehukama, yakakodzera kwazvo. yekudzora kuyerera. Nokudaro, rudzi urwu rwevhavha rinonyatsogadziriswa pakucheka kana kugadzirisa uye kuputika.
Zvakanakira: ① Mukuvhura nekuvhara maitiro, nekuti kupokana pakati pedhisiki nevhavhavha yemuviri yekuisa chisimbiso pamusoro idiki pane iyo yevhavha yegedhi, saka haibatike. (2) Kureba kwekuvhura kunowanzo 1/4 yemugero wechigaro, saka idiki zvakanyanya pane vharafu yegedhi; (3) Kazhinji pane imwe chete yekuisa chisimbiso pamusoro pemuviri wevhavha uye valve disc, saka nzira yekugadzira iri nani uye iri nyore kuchengetedza. (4) Nekuti kuzadza kwayo kunowanzo musanganiswa weasbestos uye graphite, saka tembiricha yekudzivirira giredhi yakakwira. Mavharuvhu anowanzo shandisa mavharuvhu ekumisa.
Zvakaipa: (1) Nemhaka yokuti kuyerera kwemaitiro epakati kuburikidza nevhavha yakashanduka, saka kupikisa kuduku kwekuyerera kwevhavha yakachekwa yakakwirira kudarika mamwe marudzi akawanda evhavha; ② Nekuda kwekufamba kwenguva refu, kumhanya kwekuvhura kunononoka kupfuura vheji yebhora.

Jongwe:
Inoreva vheji inotenderera ine chikamu chekuvhara seplunger, iyo inogona kuvhurwa kana kuvharwa kuburikidza ne90 ° kutenderera kuitira kuti chiteshi chevhavhavhavha chitaurirwe kana kuparadzaniswa kubva pachiteshi chevhavha muviri. Iyo plug inogona kuve cylindrical kana conical muchimiro. Nheyo yaro inonyanya kufanana nevhavha yebhora, vheji yebhora inogadzirwa pamusana pevhavha yevhavha, inonyanya kushandiswa mukushandiswa kwemafuta emunda, asi inoshandiswawo mune petrochemical industry.

Steam trap:
Mukufambiswa kweutsi, mhepo yakamanikidzwa uye mamwe midhiya, pachave nekumwe kuumbwa kwemvura, kuitira kuti ive nechokwadi chekushanda uye kushanda kwakachengeteka kwechishandiso, inofanirwa kuburitswa nenguva yeiyi midhiya isina basa uye inokuvadza, kuve nechokwadi chekushandisa uye nekuchengetedzeka. kushandisa mudziyo. Iine mabasa anotevera: (1) inogona kukurumidza kubvisa condensate yakagadzirwa; ② Kudzivirira kubuda kwemhepo; ③ Usasanganise mhepo uye mamwe asingatsikidzi magasi.
8
Kuderedza vharafu:
Ivharuvhu inoderedza inlet kudzvanywa kune inodiwa yekubuda kumanikidza nekuigadzirisa, uye inovimba nesimba repakati pachayo kuchengetedza iyo yekubuda pressure yakagadzikana yega.
