I-valve esisiseko

A ivalvesisixhobo solawulo somgca wamanzi. Umsebenzi wayo osisiseko kukuxhuma okanye ukunqunyulwa isangqa se-pipeling, tshintsha indlela yokuhamba kwe-Pipeli, lungisa uxinzelelo kunye nokuhamba kwephakathi, nokukhusela ukusebenza kwesiqhelo kombhobho kunye nezixhobo.

一.Ukuhlelwa kweevalves

Ngokokwenza umsebenzi kunye nomsebenzi ungahlulelwa ukuba:

I-1. Vala i-Valve ye-Valve: Sika okanye uqhagamshele i-piiliel ephakathi. Enje,, i-valve yesango, ivalve ye-globe, i-valve yebhola, ibhotwe yebhabhathane, i-Diaphragm Valve, iPlve.

2. Jonga i-valve: Thintela i-Pipeliline ekuqhubeni ukusuka ekuhambeni ngasemva.

3. I-Volve yokuHambisa: Guqula indlela yokuhamba yendawo, yokuhambisa, ukwahlula okanye ukuxuba iphakathi. Njengamava evalini, imigibe ye-Steam, kunye neeHlangani zeendlela ezintathu.

4. IValve elawula: lungisa uxinzelelo kunye nokuhamba kwephakathi. Enjengoxinzelelo lokuphelisa ivalve, elawula ivalve, ivalve ecekeceke.

5. Valve Ezokhuseleko: Thintela uxinzelelo oluphakathi kwisixhobo ukusuka kwixabiso eligqithileyo, kunye nokubonelela ngokhuseleko loKhuseleko loKhuseleko.

二. Iiparamitha ezisisiseko zeivalve

1. Ububanzi be-valve (DN).

2. Uxinzelelo oluthile lwevalve (PN).

3. Uxinzelelo kunye neqondo lobushushu le-valve: Xa amaqondo obushushu evalve engaphezulu kweqondo lokushishina loxinzelelo olufanelekileyo, uxinzelelo lwayo oluninzi kufuneka luncitshiswe ngokufanelekileyo.

I-4. I-Valve I-Valve Ingxokolo:

I-5. Iphakathi kweivalve:

Ii-valves ze-mveliso zisetyenziswa kwi-petroleum, ishishini lekhemikhali, i-metallggy, amandla ombane, amandla enyukliya kunye namanye amashishini. Amajelo eendaba adlulisela ukubandakanya iigesi (umoya, i-Steam, i-Amon, igesi yeChithi, igesi yepetrole, igesi yendalo, njl.njl.); Ulwelo (amanzi, i-ammonia yolwelo, ioyile, acid, ialkalis, njl. njl.). Ezinye zazo zihambelana nemipu yomatshini, kwaye ezinye zinerakhi.
