Valve ya Xisekelo

A valvei xitirhisiwa xo lawula layini ya mati. Ntirho wa yona wa xisekelo i ku hlanganisa kumbe ku tsema ku rhendzeleka ka ring ya phayiphi, ku cinca ndlela yo khuluka ya xitirhisiwa, ku lulamisa ntshikelelo na ku khuluka ka xitirhisiwa, na ku sirhelela matirhelo ya ntolovelo ya phayiphi na switirhisiwa.

一.Ku hlawuriwa ka ti valve

Hi ku ya hi matirhiselo na ntirho swi nga avanyisiwa hi:

1. Valve yo pfala: tsema kumbe ku hlanganisa xitirhisiwa xa phayiphi. Ku fana na: valve ya gede, valve ya globe, valve ya bolo, valve ya phaphatani, valve ya diaphragm, valve ya plug.

2. Ku kambela valve: sivela xitirhisiwa lexi nga eka phayiphi leswaku xi nga khuluki xi tlhelela endzhaku.

3. Valve yo hangalasa: cinca ndlela yo khuluka ya xitirhisiwa, hangalasa, hambanyisa kumbe ku hlanganisa xitirhisiwa. Kufana na ti valve to hangalasa, ti steam traps na ti three-way ball valves.

4. Valve yo lawula: lulamisa ntshikelelo na ku khuluka ka xitirhisiwa. Kufana na valve yo hunguta ntshikelelo, valve yo lawula, valve ya throttle.

5. Valve ya vuhlayiseki: sivela ntshikelelo wa le xikarhi eka xitirhisiwa ku tlula mpimo lowu vekiweke, naswona u nyika nsirhelelo wa vuhlayiseki bya ntshikelelo wo tlula mpimo.

二. Tipharamitha ta xisekelo tavalve

1. Diameter ya vito ya valve (DN).

2. Ntshikelelo wa vito wa valve (PN).

3. Ntshikelelo na mahiselo ya valve: Loko mahiselo yo tirha ya valve ya tlula mahiselo ya reference ya ntshikelelo wa vito, ntshikelelo wa yona lowukulu wo tirha wu fanele ku hungutiwa hi ku ya hi sweswo.

4. Ku hundzuriwa ka yuniti ya ntshikelelo wa valve:

5. Xitirhisiwa lexi tirhaka xavalve:

Ti valve ta tiindasitiri ti tirhisiwa eka petroliyamu, indasitiri ya tikhemikhali, tinsimbi, gezi, eneji ya nyutliya na tiindasitiri tin’wana. Swihangalasamahungu leswi hundzaka eka swona swi katsa tigasi (moya, mpfula, ammonia, gasi ya malahla, gasi ya petroliyamu, gasi ya ntumbuluko, na swin’wana); swilo leswi nga mati (mati, ammonia leyi nga mati, mafurha, ti-acid, ti-alkali, na swin’wana). Tin’wana ta tona ti onha ku fana ni swibamu swa michini, kasi tin’wana ti ni miseve yo tala.
