Valve ea ho Leka-lekanya e Lokela ho Kenngoa Hokae

Li-valve tsa ho leka-lekanyake likarolo tsa bohlokoa lits'ebetsong tsa HVAC le hydronic, tse sebelisoang ho laola le ho laola phallo ea mokelikeli ho fihlela ts'ebetso e bolokang matla, e tsitsitseng le e tšepahalang. Empa baqapi ba bangata ba lits'ebetso le lihlopha tsa tlhokomelo hangata ba botsa:valve ea ho leka-lekanya e lokela ho kenngoa hokae hantleho netefatsa tshebetso e phahameng ka ho fetisisa?

A re qoeleng ka botebo karabong, re shebe mekhoa ea indasteri, mabaka le maano a ho beha, ha re ntse re ntlafatsa mantsoe a bohlokoa a ho batla joalo ka ho kenya li-valve tse leka-lekaneng, sebaka sa li-valve tse leka-lekaneng tsa HVAC, le moralo oa sistimi ea hydronic.

Valve ea ho Leka-lekanya ke Eng

Valve ea ho leka-lekanya ke sesebelisoa se sebelisetsoang ho laola phallo ea mokelikeli lits'ebetsong tsa ho futhumatsa le ho pholisa. E thusa ho boloka sekhahla se nepahetseng sa phallo, ho netefatsa hore likarolo tsohle tsa moaho li fumana matla a mocheso a nepahetseng, ebang ke metsi a chesang kapa a batang. Livalve tsena li bohlokoa ho qoba mathata a kang ho futhumala ka tlase ho mocheso, ho chesa haholo, kapa tšebeliso e sa sebetseng hantle ea matla.

Ho na le mefuta e 'meli e meholo:

• ①Li-valve tsa ho leka-lekanya tsa letsoho(e sebelisetsoa litsamaiso tse sa fetoheng)

• ②Li-valve tsa ho leka-lekanya tse iketsang(e loketse litsamaiso tse fetohang)

Kahoo, Valve ea ho Leka-lekanya e Lokela ho Kenngoa Hokae

1. Ka lehlakoreng la ho Khutlela la Yuniti ea Terminal (Sebaka se Khethiloeng)

Mekhoeng e mengata ea sejoale-joale ea HVAC—haholo-holo e kenyeletsang li-unit tsa fan coil (FCUs), li-unit tsa ho sebetsana le moea (AHUs), kapa mahlakore a pholileng—valve ea ho leka-lekanya e kenngoa moleng oa ho khutla, o theohelang tlase ho coil kapa yuniti ea terminal.

Hobaneng?

• ①Tekanyo e Nepahetseng ea Phallo: Mohala oa ho khutla o fana ka setšoantšo se betere sa phallo eohle ka har'a yuniti.

• ②Ho Tlosa Moya: Ho fokotsa kotsi ya ho tshwasa moya tsamaisong kaha moya o atisa ho bokellana methating ya phepelo, mme ha o batle hore o kgomarele haufi le ntlha ya ho lekanya.

• ③Molemo oa ho Hlatsoa: Ho kenya moleng oa ho khutlisa ho lumella sistimi ho hlatsoa habonolo ho tloha phepelong ho ea lehlakoreng la ho khutlisa.

2. Qetellong ea Lekala le Leng le le Leng le Leholo kapa Potoloho e Nyenyane

Litsamaisong tse rarahaneng tsa hydronic tse nang le li-loop kapa libaka tse ngata, joalo ka mehahong e nang le mekato e mengata kapa litsamaisong tse kholo tsa khoebo, li-valve tsa ho leka-lekanya li kenngoa qetellong ea potoloho ka 'ngoe ho netefatsa:

• ①Kabo e lekanang ea khatello

• ②Phallo e lekanang lekaleng ka leng

• ③Tekanyo ea tsamaiso ka bophara

Sebopeho sena se loketse litsamaiso tsa liphaephe tse se nang sekotjana (mohlala, litsamaiso tsa ho khutlisa morao kapa tsa ho khutlisa ka kotloloho).

3. Li-valve tsa Taolo Pele kapa Kamora (Ho latela Moralo)

Disistiming tse nang le di-valve tsa taolo tse ikemetseng ka kgatello (di-PICV), ho leka-lekanya ho ka sebetswa kahare, mme di-valve tse ding tsa ho leka-lekanya di kanna tsa se hlokehe boemong ba yuniti ya terminal. Empa disistiming tse nang le di-valve tsa taolo tse nang le mahlakore a mabedi mme di se na di-PICV, valve ya ho leka-lekanya e ntse e lokela ho bewa ka mora coil le valve ya taolo, moleng wa ho kgutlela.

4. Lihlooho tsa Pump Discharge (Bakeng sa ho Leka-lekanya Sistimi)

Bakeng sa litsamaiso tsa mantlha-tse peli kapa litsamaiso tsa phallo ea mantlha tse feto-fetohang, li-valve tsa ho leka-lekanya li ka boela tsa sebelisoa:

• ①Lihlooho tsa ho ntša metsi pompong

• ②Meleng e fetang kapa libakeng tse aroloang

Sena se thusa ho laola khatello e fapaneng le ho tsitsisa ts'ebetso ea sistimi.

Malebela a ho Kenya

• ①Sebedisa di-valve tsa ho leka-lekanya tse nang le dikou tsa ho lekanya phallo ho dumella ho qala ka potlako.

• ②Beha di-valve libakeng tse ka fihlellehang habonolo bakeng sa tokiso le tlhokomelo e tsoelang pele.

• ③Nahana ka litekanyetso tsa mocheso le khatello tse loketseng litlhaloso tsa sistimi ea hau.

• ④Leka-lekanya sistimi o sebedisa disebediswa tse ikgethang kapa dimethara tsa phallo ya dijithale bakeng sa ho nepahala.

• ⑤ Kopanya le balaoli ba khatello e fapaneng kapa li-PICV lits'ebetsong tsa phallo e matla.
