Chii chinonzi High Performance Butterfly Valves (HPBVs)?

1. Ndezvipi mavharuvhu emhando yepamusoro ebhatafurayi

Vharuvhu yemapuruguru inoshanda zvakanyanya inoreva rudzi rutsva rwechigadzirwa chemabhuruvhu emapuruguru chinovandudza kuvharwa nekusakara kwemavharuvhu emapuruguru, chinowedzera kupesana nekupisa kwakanyanya uye kuramba ngura, uye chinovandudza hupenyu hwebasa uye kuvimbika zvichibva pamavharuvhu emapuruguru akajairwa (mavharuvhu emapuruguru nemavharuvhu emapuruguru matatu eccentric) nekuvandudza chimiro nezvinhu. Zvichienzaniswa nemavharuvhu emapuruguru akajairwa, mavharuvhu emapuruguru anoshanda zvakanyanya ane hupenyu hwakareba, torque yakareruka, huwandu hwakakura hwekushandiswa, uye kushanda zvakanaka kwekuvhara.

Mavharuvhu eshavishavi anoshanda zvakanaka (HPBVs) anomiririra shanduko yepamusoro yedhizaini yemavharuvhu eshavishavi. Akagadzirwa kuti avhare, agare kwenguva refu, uye adzorerwe zvakanaka mukushandiswa kwakakosha, ane madhisiki edhisiki eoffset (akapetwa kaviri kana katatu) uye anoshandisa zvisimbiso zvesimbi-ku-simbi kana zvinogara kwenguva refu. Kusiyana neawo akabatana,mavharuvhu eshavishavi anoshanda zvakanyanyaVanogona kubata nekumanikidzwa kwakanyanya, tembiricha dzakanyanya, zvinhu zvinoparadza, uye vanovhara zvinhu zvakasimba, zvichiita kuti zvive zvakakosha mumabasa emazuva ano emaindasitiri.

1.1 Zvikamu Zvikuru zveVharuvhuti yeBhatafurayi: Kubatanidza Muviri, Dhisiki, Hunde, Chigaro, uye Actuator

Zvikamu zvikuru zvevharuvhu remashavishavi zvinowira muzvikamu zvishanu zvikuru: muviri wevharuvhu, dhisiki remashavishavi, hunde yevharuvhu, chigaro chekuvharira, uye zvikamu zvekubatanidza zveactuator.

•Muviri weVharuvhu: Muviri wevharuvhu unoshanda seganda guru rekunze, riine kumanikidzwa kwepaipi uye mutoro wepakati ukuwo richishanda sehwaro hwekugadzika kwezvimwe zvikamu zvese. Rinowanikwa mumhando yewafer nelug-type, rinowanzo gadzirwa nesimbi yakakandwa, simbi yekabhoni, kana simbi isingatsvi.

•Dhisiki reVharuvhu: Dhisiki reshavishavi ndiro chinhu chakakosha pakuvhura, kuvhara, uye kukwenya. Dhizaini yaro yakaita sedhisiki, inowanikwa muchimiro chakabatana kana chisina kujairika, inosarudza zvakananga mashandiro ekuvhara uye kuramba kupfeka. Inofanira kuramba ngura nekukukurwa.

•Hunde yeVharuvhu: Chigadziko chevharuvhu chinotumira simba, chichibatanidza actuator kudhisiki kuti ikwanise kufamba-famba. Kazhinji inogadzirwa nesimbi isingatsvedzi, ine magadzirirwo akasimbiswa uye akakura ekushandisa dhayamita hombe, ane simba guru kudzivirira kukotama kana kushanduka.

•Chigaro cheVharuvhu:Chigaro chinovhara ndicho chinhu chikuru chinoita kuti chivharwe zvakasimba. Chinouya murabha inovhara zvinyoro nyoro kana simbi inovhara zvakasimba, ichinyatsobatana nedhisiki kuti isaburitse mvura zvachose.

•Actuator: Zvikamu zvekubatanidza actuator zvinosanganisira mibato, magiya ehonye, ​​uye ma actuator emagetsi/pneumatic. Zvinopa torque inodiwa pakuvhura nekuvhara, zvichibatsira pakushanda nemaoko pamwe ne automated remote control. Zvikamu zvese zvinoshanda pamwe chete kuti zvive nechokwadi chekuti kushanda kwakasimba, kuvhara kwakavimbika, uye kudzora kwakarurama kwevharuvhu remapuruguru.

1.2 Kuongororwa Kwepfungwa Yekugadzira Zvivako zveVharuvhuti Yepamusoro-soro

Vharuvhu yemashavishavi inoshanda zvakanaka ivharuvhu yemashavishavi yakagadzirwa nemazvo, yakakodzera kudzora kuyerera kwemvura uye kumanikidzwa kwayo muzvinhu zvakaita semvura yepombi, mvura yemumaindasitiri, mvura yakasviba, mhepo, HVAC, gasi remuguta, uye LPG. Kana yakavharwa, vharuvhu haibudisi mvura zvachose.

Chigaro chevharuvhu chine dhizaini yekuvhara curve yeCOS, iyo inoderedza kukweshana pakati pedhisiki nechigaro, inoderedza torque yeactuator, uye inowedzera hupenyu hwechigaro. Maitiro ayo ekuvhara akafanana nevharuvhu ine mativi maviri. Nzvimbo yekuvhara dhisiki yakaita sedenderedzwa, zvichiita kuti kubatana kunyorove panguva yekuvhara. Kukweshana kushoma, kunyanya pachivharo cheshaft, kunowedzera hupenyu hwechigaro. Ringi rekuchengetedza simbi mukati merin'i rechigaro rinovhara yega chero mukaha uri pakati pesimbi nerin'i rechigaro kana tsinde iri pasi pemasimba asina kuenzana, zvichibvisa mukana wekubuda kweaxial.

•Kona yeCOS: Dhizaini yekuvharira curve yeCOS inoita kuti torque isakwire isati yavharwa. Panguva yekuvharwa, dhisiki inosangana nerin'i yechigaro panguva imwe chete mudenderedzwa rese re360°, zvichideredza kukweshana, kuderedza torque, kuwedzera hupenyu hwechigaro, uye kuchengetedza kusabuda kwemvura panguva yekushanda kwenguva refu. Kukweshana kwakaderera uye torque zvinobvumira kushandiswa kweactuators dzine simba shoma, zvichideredza mari yemushandisi.

•Dhisiki Yakagadzikwa Muchina: Dhisiki iyi yakagadzirwa nesimbi yakagadzirwa kuita denderedzwa rakakwana, chikamu chimwe nechimwe chepasi pese chinoumba chikamu chedenderedzwa. Dhisiki nerin'i yechigaro zvinogadziriswa kuita denderedzwa rakafanana, zvichikonzera kushaikwa kudiki uye kusakweshana. Dhisiki iyi inotenderera zvakanaka, kunyangwe panzvimbo dze sealing dze axial kumusoro nepasi. Pasinei nekubata, nzvimbo dze sealing dzakanyatsotsvedzerera, zvichideredza torque uye zvichiwedzera kushanda kwe sealing.

•Valve yeButterfly yePTFE-Yakatsetseka Yepamusoro-soro: Vharuvhu iyi ine ganda remuviri rakafukidzwa nePTFE uye inoshandiswa zvakanyanya mukudya, mishonga yemishonga, zvemagetsi, nezvimwe zvinoshandiswa muhutsanana kudzora kana kudzora kuyerera nekumanikidzwa kwemvura dzakasiyana-siyana, pamwe chete nekushandiswa kwemakemikari muindasitiri ine maasidhi akasimba, alkalis akasimba, uye magasi anoparadza zvakanyanya. Inopa kugara kwenguva refu, kushanda zvakanaka kwekuvhara, uye kuramba ngura, zvichiita kuti isaburitse mvura kana yavharwa.

•Dhizaini yeChisimbiso cheI-Type: Dhizaini yerin'i yechisimbiso inoita kuti rabha neTeflon zvisashande pamwe chete asi zvichibatsirana, zvichiwedzera kushanda kweseinning. Kushandiswa kwerabha kunowedzera kusimba kwechisimbiso ukuwo kuchideredza huwandu hwerabha hunodiwa, zvichibvisa njodzi yekuvharika kwemadiski panzvimbo yakavharwa nekuda kwekuwedzera kwerabha kubva pakupisa.

Kuvandudzwa Kwekushanda Kwekuvhara kweDhizaini Itsva Yemavharuvhu Emhando Yepamusoro Yekushanda:

a. PFA jira rine ukobvu hwe3 mm kana kupfuura rinodzivirira kupinda kwemagasi akasiyana-siyana uye rinopa simba rakasimba rekudzivirira ngura.

b. Masipiringi anowedzerwa mumabhokisi ekurongedza epamusoro neepasi kuti akunde mhedzisiro yekuchinja-chinja kwekushisa pakuvharwa.

2. Mavharuvhu Ekushanda Kwakanaka Zvichienzaniswa neMavharuvhu Akajairwa: Misiyano Yakakosha
