3. Inogona kushandiswa kune midhiya ine yakaturikwa yakasimba particles, uye inogona zvakare kushandiswa kune upfu uye granular media maererano nesimba rekuisa chisimbiso pamusoro.Inokodzera nzira mbiri-kuvhura nekuvhara uye kugadzirisa kwemhepo uye kubvisa guruva pombi, uye inoshandiswa zvakanyanya mumapombi egasi uye nzira dzemvura mumetallurgy, indasitiri yemwenje, simba remagetsi, petrochemical system, nezvimwe.

kukanganisa:
1. Kuyerera kwekugadzirisa mararamiro hakusi kukuru.Kana kuvhura kunosvika 30%, kuyerera kuchapinda kupfuura 95%.
2. Nekuda kwekuganhurirwa kweiyo butterfly valve chimiro uye yekuisa chisimbiso zvinhu, haina kukodzera kutonhora kwakanyanya uye yakanyanya kudzvanywa pombi system.Iyo tembiricha yekushanda yakawanda iri pasi pe300 ° C uye pasi pePN40.
3. Chisimbiso chekuita chisimbiso chakashata kupfuura icho chevhavha yebhora uye globe mavharuvhu, saka inoshandiswa munzvimbo dzinodiwa zvekuisa chisimbiso hazvisi zvakanyanya.

3. Vhuru yebhora: Yakavepo kubva pavharuvhu.Chikamu chayo chekuzarura nekuvhara chikamu, uye mutumbi wekuvhara unotenderedzwa 90 ° kumativi e-axis ye stem yevhavha kuti uwane chinangwa chekuzarura nekuvhara.Ivhavhavha yebhora inonyanya kushandiswa kucheka, kugovera uye kushandura mafambiro epakati papombi, uye vharafu yebhora yakagadzirwa nekuvhura kwakaita V inewo basa rakanaka rekutonga kuyerera.

advantage :
1. Iine yakaderera kuyerera kuramba (chaizvoizvo 0);
2. Nekuti haizobatiki kana ichishanda (mumafuta), inogona kuvimbika kuiswa kune inoora midhiya uye yakaderera yekubikira zvinwiwa;
3. Mune yakakura kumanikidza uye tembiricha renji, inogona kuwana chisimbiso chakakwana;
4. Inogona kuona nekukurumidza kuvhura nekuvhara.Nguva yekuvhura uye yekuvhara yezvimwe zvimiro ingori 0.05 ~ 0.1s, kuitira kuti ive nechokwadi chekuti inogona kushandiswa mune otomatiki system yebhenji rekuyedza.Pakuvhura nekuvhara valve nekukurumidza, hapana kuvhunduka mukushanda.
5. Iyo spherical inovhara nhengo inogona kuiswa yega panzvimbo yemuganhu;
6. Chishandiso chekushanda chakavharwa zvakavimbika kumativi ose;
7. Kana yakanyatsozaruka uye yakavharwa zvakakwana, nzvimbo yekuvhara bhora uye chigaro chevhavha inoparadzaniswa kubva pakati, saka iyo yepakati inopfuura nepakati pevhavha nekukurumidza haizokonzeri kukukurwa kwenzvimbo yakavharwa;
8. Iine compact dhizaini uye huremu huremu, inogona kutariswa seyakanyanya kunzwisisika vharafu chimiro chepasi tembiricha yepakati system;
9. Muviri wevharuvhu wakaenzana, kunyanya iyo welded valve body structure, iyo inogona kumira zvakanaka kushushikana kubva pombi;
10. Zvikamu zvekuvhara zvinogona kumira mutsauko wepamusoro kana uchivhara.
11. Ivhavha yebhora ine muviri wakazara welded inogona kuvigwa zvakananga muvhu, kuitira kuti zvikamu zvemukati zvevhavha zvirege kusvibiswa, uye hupenyu hwepamusoro hwebasa hunogona kusvika makore makumi matatu.Ndiyo yakanakisa vharafu yemafuta uye gasi egasi mapaipi.

kukanganisa:
1. Nekuti inonyanya kukosha chigaro chekuisa chisimbiso chevhavhavhavhavhavharu ndeye polytetrafluoroethylene, inert kunenge zvese makemikari zvinhu, uye ine diki friction coefficient, yakagadzikana kuita, isiri nyore kuchembera, yakafara tembiricha yekushandisa uye yekuisa chisimbiso. .Nekudaro, izvo zvemuviri zvePTFE, kusanganisira yakakwira coefficient yekuwedzera, sensitivity kune kutonhora kuyerera uye kushata kwemafuta ekupisa, zvinoda kuti zvisimbiso zvechigaro zvinofanira kugadzirwa zvakatenderedza zvivakwa izvi.Naizvozvo, kana iyo yekuisa chisimbiso ichiomesa, kuvimbika kwechisimbiso kunokanganiswa.Uyezve, PTFE ine yakaderera tembiricha chiyero uye inogona chete kushandiswa pazasi 180 ° C.Pamusoro pe tembiricha iyi, chisimbiso chinozochembera.Panyaya yekushandiswa kwenguva refu, haiwanzo shandiswa pa120 ° C.
2. Kugadzirisa kwayo kushanda kwakaipisisa kudarika kwevhavha yepasi, kunyanya pneumatic valve (kana magetsi emagetsi).

4. Globe valve: inoreva vharafu ine nhengo yekuvhara (disc) inofamba nepakati pechigaro chevharuvhu.Maererano nefomu yekufambisa ye disc, kuchinja kwechiteshi chechigaro chevhavha inofananidzwa nekurohwa kwe disc.Nekuti kuvhurika kana kuvhara kwevharuvhu yerudzi urwu rwevharuvhu ipfupi, uye ine yakavimbika kwazvo yekucheka-kubvisa basa, uye nekuti shanduko yekuvhurwa kwechigaro chevhavha inoenzanirana nekurohwa kwevhavha disc, iyo yakanyatsokodzera kugadzirisa kuyerera.Nokudaro, rudzi urwu rwevhavha runonyatsokodzera kucheka kana kudzora uye throttling.

mukana:
1. Panguva yekuzarura nekuvhara, sezvo simba rekukwevera pakati pe diski uye chisimbiso chepamusoro chemuviri wevhavha iduku kudarika yevhavha yegedhi, inopfeka-inopesana.
2. Kureba kwekuvhura kunowanzo kungoita 1/4 chete yechigaro chechigaro, saka idiki zvakanyanya pane gedhi vharafu;
3. Kazhinji pane imwe chete chisimbiso pamusoro pemuviri wevhavha uye disc valve, saka nzira yekugadzira inenge yakanaka uye iri nyore kuchengetedza.
4. Sezvo iyo filler iri kazhinji musanganiswa weasbestos uye graphite, tembiricha yekupikisa mwero yakakwira.Kazhinji mavharuvhu eutsi anoshandisa mavharuvhu epasi.

kukanganisa:
1. Sezvo kuyerera kwenzira yepakati kuburikidza nevhavha yakashanduka, kushoma kuyerera kwekudzivirira kwevhavhavha yeglobe zvakare yakakwirira kudarika mamwe marudzi akawanda evhavha;
2. Pamusana pekurohwa kwenguva refu, kukurumidza kwekuvhura kunononoka kudarika yevhavha yebhora.

5. Plug valve: Inoreva vheji inotenderera ine plunger-yakaita chikamu chekuvhara.Kuburikidza ne90 ° kutenderera, chiteshi chechiteshi pane plug yevharuvhu chakabatana kana kupatsanurwa kubva pachiteshi chechiteshi pane muviri wevharuvhu kuti uone kuvhura kana kuvhara.Chimiro chevhavhavhavha inogona kuva cylindrical kana conical.Nheyo yayo inonyanya kufanana neyevhavha yebhora.Ivhavha yebhora inogadzirwa pahwaro hwevhavhavhavha.Inonyanya kushandiswa mukushandiswa kwemafuta mumunda uye zvakare muindasitiri ye petrochemical.

6. Kuchengetedza vharafu: inoshandiswa sechidziviriro chekudzivirira zvakanyanya pamidziyo yekumanikidza, zvishandiso kana mapaipi.Kana kudzvinyirirwa mumudziyo, mudziyo kana pombi inokwira pamusoro pekukosha kunobvumirwa, vheji inovhurika otomatiki uye yobva yabuda zvizere kudzivirira mudziyo, mudziyo kana pombi uye kudzvanywa kubva pakuramba kuchikwira;apo kudzvinyirirwa kunodonha kune kukosha kwakatarwa, vharuvhu inofanira Kuvhara pakarepo munguva yekudzivirira kushanda kwakachengeteka kwemidziyo, midziyo kana mapaipi.

7. Steam trap: Imwe mvura yakapfupikiswa ichaumbwa mukutakurwa kweutsi, mweya wakatsikirirwa uye mamwe midhiya.Kuti ive nechokwadi chekushanda zvakanaka uye kushanda kwakachengeteka kwechishandiso, aya asingabatsiri uye anokuvadza midhiya anofanirwa kuburitswa nenguva kuti ive nechokwadi chekushandisa uye kuchengetedzeka kwechishandiso.use.Iine mabasa anotevera: 1. Inogona kukurumidza kubvisa mvura yakasvibiswa;2. Kudzivirira kubuda kwemhepo;3. Bvisa mweya uye mamwe magasi asingapindiki.

8. Kudzvinyirira kuderedza valve: Ivharuvhu inoderedza inlet kumanikidza kune imwe inodiwa yekubuda kumanikidza kuburikidza nekugadzirisa, uye inotsamira pane simba repakati pachayo kuti ichengetedze yakagadzikana yekubuda kudzvanywa.

9. Tarisa vharafu: inozivikanwawo sereverse flow valve, check valve, back pressure valve uye imwe-nzira valve.Aya mavharuvhu anovhurwa otomatiki uye anovharwa nechisimba chinogadzirwa nekuyerera kwepakati pachayo mupombi, inova rudzi rweotomatiki valve.Ivhavha yecheki inoshandiswa muhurongwa hwepombi, uye basa rayo guru nderokudzivirira kutenderera kutenderera kwepakati, kutenderera kutenderera kwepombi uye motokari yemotokari, uye kubudiswa kwemukati wemudziyo.Cheki mavharuvhu anoshandiswawo pamitsetse inopa ebetsero masisitimu uko kudzvanywa kunogona kukwira pamusoro pekumanikidza kwehurongwa.Inogona kunyanya kukamurwa kuita swing type (inotenderera zvinoenderana nepakati pesimba rinokwevera pasi) uye yekusimudza mhando (inofamba neaxis)
