Iimpawu zepenstock

Okubizwa ngokuba ngumbhobho woxinzelelo kubhekiselele ekusetyenzisweni koxinzelelo lokuthutha igesi, ulwelo, njl njl. Kodwa ayizizo zonke iipayipi ezinokubizwa ngokuba yimibhobho yoxinzelelo. Iimeko ezimbini: 1. Uxinzelelo> = 0.1MPa (uxinzelelo lwe-gauge) 2. Ipayipi DN> = 25mm Uphawu 1. Umbhobho woxinzelelo yinkqubo, ukutsala injini enye kunye nokuhambisa umzimba wonke. 2. Umlinganiselo wobude ukuya kububanzi bombhobho mkhulu kakhulu, kulula ukulahlekelwa ukuzinza, kwaye imeko yoxinzelelo inzima ngakumbi kunomkhumbi woxinzelelo. 3. Isimo sokuhamba kwamanzi kumbhobho siyinkimbinkimbi, indawo ye-buffer incinci, kunye nokutshintsha rhoqo kweemeko zokusebenza kuphezulu kunomkhumbi woxinzelelo (njengokushisa okuphezulu, uxinzelelo oluphezulu, ubushushu obuphantsi, uxinzelelo oluphantsi. , i-deformation deformation, umoya, ikhephu, inyikima, njl., Enokuthi ichaphazele uxinzelelo lwepayipi yoxinzelelo). 4. Kukho iintlobo ezininzi zecandelo lombhobho kunye nokuxhaswa kombhobho, into nganye ineempawu zayo kunye neemfuno ezithile zobugcisa, kwaye ukukhethwa kwezinto eziphathekayo kuyinkimbinkimbi. 5. Kukho iindawo zokuvuza ezinokwenzeka ngakumbi kumbhobho kunomkhumbi woxinzelelo. Ngokubanzi, kukho amanqaku amahlanu kwivalve enye. 6. Kukho iintlobo ezininzi kunye nobuninzi bemibhobho yoxinzelelo, kwaye kukho izixhumanisi ezininzi ekuyilweni, ekuveliseni, ekufakeni, ekuhloleni nasekulawuleni izicelo, ezihluke kakhulu kwiinqanawa zoxinzelelo.
