Isishwankathelo semveliso

Ivalve yeglowubhu, ekwabizwa ngokuba yivalve yokuvala, yeyevalve yokutywina ngenkani, ke xa ivelufa ivaliwe, kufuneka kufakwe uxinzelelo kwidiski yevalve ukunyanzela umphezulu wokutywina ungavuzi. Xa i-medium ingena kwi-valve esuka ngaphantsi kwe-disc, ukuchasana okufuneka ukuba amandla okusebenza aphumelele yi-friction force yentonga kunye nokupakisha kunye ne-thrust eveliswa luxinzelelo lwe-medium. Amandla okuvala ivalve mkhulu kunokuvulwa kwevalve, ngoko ke ububanzi be-castron kufuneka bube bukhulu, kungenjalo ukusilela kokugoba komphezulu we-stem kuya kwenzeka. Ngokwendlela yoqhagamshelo, yahlulwe yaba ziindidi ezintathu: uqhagamshelo lwe-flange, uqhagamshelo lwesilika kunye noqhagamshelo lwe-welding. Ukusuka kwinkangeleko yevalve yokutywina, ukuhamba okuphakathi kwevalve yeglowubhu kuyatshintshwa ukusuka phezulu kwevalve ukuya kwigumbi levalve, emva koko phantsi kwesenzo soxinzelelo oluphakathi, amandla okuvala ivalve mancinci, kunye namandla okuvula ivalve. ivalve inkulu, kwaye i-diameter yesiqu inokuncitshiswa ngokufanelekileyo. Kwangaxeshanye, phantsi kwesenzo se-medium, olu hlobo lwevalve lukwangqongqo ngakumbi. Ivalve yaseTshayina "ezintathu ukuya" ichaze ukuba i-flowdirection yevalve yeglowubhu iphezulu-ezantsi. Xa ivalve yeglowubhu ivuliwe, ukuphakama kokuvula kweflap yokufunda yi-25% ukuya kwi-30% yedayamitha yegama, kwaye ukuhamba kuye kwafikelela kwinqanaba eliphezulu, ebonisa ukuba ivalve ifikelele kwindawo evuleleke ngokupheleleyo. Ke ngoko, indawo evulekileyo epheleleyo yevalve yeglobhu kufuneka imiselwe ngokubetha kwediski yevalvu
