Metal uye mapurasitiki senyere pamusoro kufefetedza kungaita mumwe

Standard utsanana mitemo zvinoda kuramba inflow mhepo yakachena muimba yokutandarira uye anobudisa atopedzera. Kana imba kana furati iri vakapakata gasi nechepakati kudziyisa, kuvapo kufefetedza kunodiwa. Mano, asi nzira yokubudisa mhepo, vakapakata zvimbudzi, kicheni, choto makamuri, saunas uye zvivako zvakafanana. Small imba nenhurikidzwa imwe vakapakata hurongwa kuti zvinopa dzinongoitika mhepo kutenderera. Zvisinei, pasinei nzira kufefetedza, zvose hurongwa kazhinji uwane mhando vachishandisa pombi kana ducts kuti kufefetedza.

Ivo kumbonyanya yakareba mhando utilities, saka kufefetedza mudziyo, unobereka pakuvaka zvivako, ducts vari kuiswa parusvingo pane vakachengetedza kuvimbika menyika. Kana kuvaka ratova akavaka, uye kudiwa munhu ano kufefetedza hurongwa yakura, zvakakodzera kushandisa kwokunze kufefetedza nenyere.

kamuri Mumwe chinorehwa munechimwewo mutsinga dzinofamba nemukaka. Vose vari zvakabatana imwe chiutsi chiteshi. Kana nzvimbo iri kure mumwe (semuenzaniso, mune imwe nyika koteji) anogona kushandisa mamwe wiring zvirongwa. Chero zvazvingava, maererano chivakwa Codes, zvikwepa nokuti kufefetedza haafaniri kuyambuka gasi, mvura uye tsvina kutaurirana. Uyewo ducts arege kushandiswa kuisa mapaipi nenyere.

Kare, mhepo migero akateya chidhinha, yaiva nguva yakawanda chaizvo. Gare gare, munguva kugadzwa wegadziriro rakatanga kushandiswa kufefetedza akaita sepombi kwakakurudzira aruminiyamu kana simbi. Munguva ichangopfuura, Zvisinei, kuvaka ari akasimudzira siyana polymer zvigadzirwa, kusanganisira mapurasitiki zvigadzirwa, kushingaira kutsiva kwavo simbi vamutangira.

Usati kuziva kuti nyere nokuda kufefetedza ndiyo yakanakisisa - mapurasitiki kana simbi - zvinofanira kucherechedzwa kuti vose vanofanira kusangana mukuru zvinodiwa kufefetedza migero: kuva zvachose risingapindi mvura, akasununguka inoyerera akaverenga pamusoro ubate mhepo aibuda hakurevi kusapfuudza ndozvakajairwa nokuda ruzha pamwero, vane kumbogadzirwa kuti mudziye uye moto nemishonga, uye kuwedzera, zvinoenderana kunonyanyisa kugadzira nzvimbo.

Flanged kwokubatana zvinopa vaviri kuvakwa simbi nenyere rinopfungaira uye PVC-nyaya ezvinhu chero kunzwisisa. Zvisinei, muna nemakadhibhokisi zvivako zviri simbi nenyere kuputira mapazi zvinoda kuti chii polyvinylchloride zvachose kwete zvinodiwa.

Kana isu vaitaurirana pamusoro urongwa kufefetedza ezvinhu chokuita kugadzirwa ngozi, kuvapo asiri combustible kwakakurudzira pombi kwaizova chinokosha. Asi dzimba pamwe raifanira kushandiswa ezvinhu zvakanaka chitarisiko uye yakawedzerwa ruzha pamwero kana mhirizhonga iri kupfeka simbi mafuta muchinjikwa. Zvisinei, kana uchida kuvaka chimbini pedo muchimbini, mumwe polymer chigadzirwa parinorambwa nokuda kukwana moto nemishonga.

Zvino kushandiswa pamwe vanachandagwinyira kusanduka chubhu nokuda kufefetedza anogona hwakakungwa chero yorusvingo, vazhinji mapurasitiki kubva kusiyana simbi uye aruminiyamu, havaiti kusika zvimwe aerodynamic zvuva maturo. Hazvina chemarata epurasitiki zvigadzirwa assemblers vanosarudza kana kushandisa kufefetedza wemuTesitamende anamapako uye nyika anamapako: ivo vanoda zvishoma mapfundo fasteners, izvo zvinoita pfupi nguva basa rinoitwa.

Saka, simbi uye PVC mapaipi kufefetedza enyika panguva kugadzwa kwavo muzvinhu zvakawanda zvakanaka kungaita mumwe, nechokwadi kuti vari vaviri utsanana uye kuvaka Codes.
