Mavharuvhu ebhoraZvine zvivakwa zvakawanda, asi zvakafanana. Zvikamu zvekuvhura nekuvhara zvine macore akatenderera, ayo anonyanya kuumbwa nezvigaro zvevharuvhu, mabhora, mhete dzekuvhara, matsinde evharuvhu nezvimwe zvishandiso zvekushanda. Chigadziko chevharuvhu chinotenderera nemadhigirii makumi mapfumbamwe kuti chivhure nekuvhara mavharuvhu. Mavharuvhu ebhora anoshandiswa pamapaipi kudzima, kugovera, kudzora kuyerera uye kushandura mafambiro epakati. Chigaro chevharuvhu chinoshandisa mafomu akasiyana ekuvhara zvigaro zvichienderana nemamiriro akasiyana ekushanda. Muviri wevharuvhu yebhora yemhando yeO une bhora rine gomba repakati nepakati rine dhayamita yakaenzana nedhayamita yepombi. Bhora rinogona kutenderera muchigaro chekuvhara. Kune rin'i ye elastic yeannular kumativi ese ari maviri munzira yepombi. Vharuvhu yebhora yemhando yeV ine chimiro chakaita seV. Musoro wevharuvhu igoko redenderedzwa re1/4 rine notch yakaita seV. Rine kugona kukuru kwekuyerera, nzvimbo yakakura inogadziriswa, simba rekuchekerera, uye rinogona kuvharwa zvakasimba. Rakakodzera zvakanyanya mamiriro emvura apo zvinhu zvine fibrous.
1. Chimiro chevharuvhu yebhora remhando yeO:
Vharuvhu yebhora yemhando yeO inodzora divi repakati nekutenderedza bhora 90°, nekudaro, gomba rinopinda rinogona kuchinjwa, nokudaro vharuvhu yebhora ichiita kuvhurika nekuvharika. Vharuvhu yebhora yemhando yeO inoshandisa dhizaini inoyangarara kana kuti yakasimbiswa. Zvikamu zvinofamba zvakagadzirwa nezvinhu zvinozvizora zvine coefficient diki kwazvo yekukweshana, saka torque yekushanda idiki. Pamusoro pezvo, kuvharwa kwenguva refu kwegrisi yekuvharira kunoita kuti mashandiro acho ave nyore. Zvakanakira chigadzirwa chayo ndeizvi:
-
Vharuvhu yebhora yemhando yeO ine simba diki rekudzivirira mvura
Mavharuvhu ebhora anowanzova nezvivakwa zviviri: dhayamita yakazara uye dhayamita yakaderedzwa. Hazvina mhosva kuti ndechipi chimiro, coefficient yekuramba kuyerera kwevharuvhu yebhora idiki. Mavharuvhu ebhora enguva dzose akatwasuka, anozivikanwawo semavharuvhu ebhora anoyerera zvizere. Dhayamita yechiteshi yakaenzana nedhayamita yemukati yepombi, uye kurasikirwa kwekuramba kunongova kuramba kwekukweshana kwehurefu hwakaenzana hwepombi. Vharuvhu iyi yebhora ine kuramba kushoma kwemvura kupfuura mavharuvhu ese. Kune nzira mbiri dzekuderedza kuramba kwesystem yepombi: imwe ndeyekuderedza mwero wekuyerera kwemvura nekuwedzera dhayamita yepombi nedhayamita yevharuvhu, izvo zvichawedzera zvakanyanya mutengo wesystem yepombi. Yechipiri ndeyekuderedza kuramba kwenzvimbo yevharuvhu, uye mavharuvhu ebhora ndiwo sarudzo yakanakisa.
-
Vharuvhu yebhora yerudzi rweO inoshanduka nekukurumidza uye zviri nyore
Vharuvhu yebhora inongoda kutenderera nemadhigirii makumi mapfumbamwe kuti ivhurike zvizere kana kuti ivharwe zvizere, kuitira kuti ivhurike nekukasika.
- Vharuvhu yebhora yemhando yeO ine mashandiro akanaka ekuvhara
Zvigaro zvemavharuvhu mazhinji zvakagadzirwa nezvinhu zvinonamira zvakaita sePTFE, izvo zvinowanzonzi mavharuvhu ebhora anonamira zvinyoro nyoro. Mavharuvhu ebhora anonamira zvinyoro nyoro ane mashandiro akanaka ekunamira uye haadi kuomarara kwakanyanya uye kunyatsogadzirwa kwenzvimbo yekunamira mavharuvhu.
-
Vharuvhu yebhora yemhando yeO ine hupenyu hurefu hwebasa
Nekuti PTFE/F4 ine hunhu hwakanaka hwekuzvizora, chiyero chekukweshana nebhora idiki. Nekuda kwetekinoroji yekugadzirisa iri nani, kuomarara kwebhora kunodzikira, nokudaro zvichiwedzera zvakanyanya hupenyu hwevharuvhu yebhora.
-
Vharuvhu yebhora yeO-rudzi ine kuvimbika kwakanyanya
Peya yekuvhara bhora nechigaro chevharuvhu hazvizokanganiswi nekukwenya, kupera nekukurumidza uye zvimwe zvikanganiso;
Mushure mekunge tsinde yevharuvhu yachinjwa kuita rudzi rwakavakirwa mukati, njodzi yetsaona yekuti tsinde yevharuvhu inogona kubhururuka nekuda kwekusunungurwa kwegland rekurongedza pasi pesimba rekumanikidzwa kwemvura kunobviswa;
Mavharuvhu ebhora ane zvivakwa zvinodzivirira kupisa uye zvinodzivirira moto anogona kushandiswa mumapaipi anotakura mafuta, gasi rechisikigo, uye gasi remarasha.
Chinoumba vharuvhu (bhora) chevharuvhu yebhora yemhando yeO chakaita sedenderedzwa. Kubva pamaonero echimiro, chigaro chebhora chakaiswa muchigaro parutivi rwemuviri wevharuvhu kana chichivharwa. Zvikamu zvinofamba zvakagadzirwa nezvinhu zvinozvizora zvine friction coefficient diki kwazvo, saka torque yekushanda idiki. Pamusoro pezvo, kuvharwa kwenguva refu kwegrisi yekuvharwa kunoita kuti mashandiro acho ave nyore. Kazhinji inoshandiswa kugadzirisa nzvimbo mbiri, hunhu hwekuyerera kwemvura hunokurumidza kuvhurika.
Kana vharuvhu yebhora yemhando yeO yakavhurika zvizere, mativi ese ari maviri haana kuvharwa, zvichiita mugero wakatwasuka une nzira mbiri dzekuvharira. Ine simba rakanakisisa re "kuzvichenesa" uye yakakodzera nguva mbiri dzekucheka dzine nzira mbiri dzisina kuchena uye dzine fiber. Bhora rinogara richikonzera kukweshana nevharuvhu panguva yekuvhura nekuvhara kwevharuvhu. Panguva imwe chete, chisimbiso pakati pevharuvhu nechigaro chevharuvhu chinowanikwa nesimba rekutanga rekuvharira chigaro chevharuvhu richidzvanya bhora. Zvisinei, nekuda kwechigaro chevharuvhu chakapfava, hunhu hwakanaka hwemakanika uye hwepanyama hunoita kuti kushanda kwaro kwekuvharira kuve kwakanaka.
2.Chimiro chevharuvhu yebhora yakaita seV:
Pakati pebhora revharuvhu rebhora rakaita seV pane chimiro chakaita seV. Pakati pevharuvhu igoko rakatenderera re 1/4 rine notch yakaita seV. Rine simba guru rekuyerera, nzvimbo yakakura inogadziriswa, simba rekuchekerera, uye rinogona kuvharwa zvakasimba. Rinonyanya kukodzera mvura. Mamiriro ezvinhu apo chinhu chacho chine fibrous. Kazhinji, mavharuvhu ebhora akaumbwa seV ivharuvhu yebhora ine chisimbiso chimwe chete. Hazvina kukodzera kushandiswa nenzira mbiri.
Kune mhando ina dze notch dzakaita seV, 15 degrees, 30 degrees, 60 degrees, 90 degrees.
Mupendero wakaita seV unobvisa tsvina. Panguva yekutenderera kwebhora, mupendero webanga rakapinza wakaita seV unonamira pachigaro chevharuvhu, nokudaro uchicheka fibers nezvinhu zvakasimba zviri mumvura. Zvisinei, mavharuvhu ebhora akajairwa haana basa iri, saka zviri nyore kukonzera tsvina yefiber kunamatira pakuvhara, zvichikonzera matambudziko ekugadzirisa nekugadzirisa. Kugadzirisa chinhu chinonetsa zvikuru. Musoro wevharuvhu wevharuvhu yebhora wakaita seV hauzonamirwi nemafibers. Pamusoro pezvo, nekuda kwekubatana kweflange, zviri nyore kupatsanura nekubatanidza pasina zvishandiso zvakakosha, uye kugadzirisa kuri nyorewo. Kana vharuvhu yavharwa, pane scissor effect pakati peV-shaped notch nechigaro chevharuvhu, iyo isingangove nebasa rekuzvichenesa chete asiwo inodzivirira bhora kuti risanamirwe. Muviri wevharuvhu, chifukidziro chevharuvhu nechigaro chevharuvhu zvinoshandisa simbi point-to-point structures, uye friction coefficient diki inoshandiswa. Valve stem yakazadzwa nechitubu, saka operating torque idiki uye yakasimba.
Vharuvhu yebhora yakaita seV chimiro chinotenderera chekona yekurudyi chinogona kudzorwa. Inogona kuwana mazinga akasiyana ehuwandu zvichienderana nekona yakaita seV yebhora rakaita seV. Vharuvhu yebhora yakaita seV inowanzo shandiswa pamwe chete nemavharuvhu actuators nemapositioners kuti igadziriswe zvakaenzana. , Vharuvhu ine chimiro cheV inonyanya kukodzera zviitiko zvakasiyana-siyana zvekugadzirisa. Ine flow coefficient yakakura, chiyero chikuru chinogadziriswa, mugumisiro wakanaka wekuvhara, hapana kunzwa mukugadzirisa, saizi diki, uye inogona kuiswa yakatwasuka kana yakatwasuka. Yakakodzera kudzora gasi, utsi, mvura nezvimwe zvinoshandiswa. Vharuvhu yebhora yakaita seV chimiro chinotenderera chekona yekurudyi, chinoumbwa nemuviri wevharuvhu yakaita seV, actuator yepneumatic, positioner nezvimwe zvinoshandiswa; ine hunhu hwekuyerera kwenzvimbo hunosvika chiyero chakaenzana; inoshandisa chimiro chine mabheya maviri, ine torque diki yekutanga, uye ine Sensitivity yakanaka uye kumhanya kwekunzwa, kugona kukuru kwekuchekerera.
