Ukuhlolwa kokusebenza kwevalvu

Amavalvuziinsetjenziswa eziqakathekileko ekukhiqizeni amabubulo, begodu ukusebenza kwazo kuthinta ngqo ukuzinza nokusebenza kuhle kwendlela yokukhiqiza. Kanengiivalvuukuhlolwa kungathola begodu kurarulule imiraro ye-valve ngesikhathi, kuqinisekise ukusebenza okujayelekileko kwe-ivalvu, begodu nokwenza ngcono ukusebenza kuhle kokukhiqiza.
Kokuthoma, ukuqakatheka kokuhlolwa kokusebenza kwevalvu

1. Qinisekisa ukuphepha nokuthembeka:Amavalvuzizinto eziqakathekileko zokulawula emapayipini wamanzi negesi, begodu zenza imisebenzi eqakathekileko ekulawuleni ukugeleza kwamanzi, ukugandeleleka nokuqondisa. Ngebanga lomthelela wezinto ezifana nendlela yokwenza, izinto kanye nomklamo, kuneengozi ezithileko ekusetjenzisweni kwamavalvu, njengokuvala okumbi, ukungabi namandla okwaneleko, ukujamelana nokugqwala okumbi, njll. Ngokuhlolwa kokusebenza, kungaqinisekiswa bona ivalvu ingakghona ukujamelana neendingo zokugandeleleka emgqeni we-fluid, begodu ibaleke ukuvuza, ukusilaphazeka, neminye imiraro yokuvala ukuqinisekisa ukusebenza okuphephileko nokuthembekileko kwehlelo.
2. Thuthukisa ikhwalithi yomkhiqizo nokuncintisana kwemakethe: Amazinga wokuhlola ukusebenza aqinileko ayisisekelo sokuqinisekisa ikhwalithi yemikhiqizo yamavalvu webubulo. Ngokulandelana kweenkambo zokuhlola, imiraro engaba khona ingatholakala begodu irarululwe, begodu ukuncintisana kwemakethe kwemikhiqizo kungathuthukiswa. Amazinga aphezulu wokuhlola godu aqinisekisa bonaivalvuihlangabezana nobujamo obuhlukahlukeneko bokusebenza, njengomthamo wokugandeleleka eendaweni ezinomfutho omkhulu, ukusebenza kokuvala ebujameni obuvaliweko, nokutjhugulula okuguquguqukako nokuthembekileko.
. Ngokuhlola nokugcina njalo, ungangezelela ipilo yamavalvu wakho begodu wehlise ukuphazamiseka kokukhiqiza kanye neendleko zokulungisa ngebanga lokuhluleka kwevalvu.
4. Ukuthobela amazinga neemfuneko zokulawula: Ukuhlolwa kokusebenza kwevalvu kutlhoga ukuthobela amazinga afaneleko weentjhabatjhaba newekhaya ukuqinisekisa bona imikhiqizo ihlangabezana neemfuneko zokuphepha nekhwalithi. Ukuthobela amazinga akusizi kwaphela bona umkhiqizo ube nesitifiketi, kodwana kwenza bona uthembeke khulu begodu uqakathekiswe emakethe.
Kwesibili, okuqukethwe kokuhlolwa kokusebenza kwe-ivalvu
1. Ukuhlolwa kokubukeka nelogo

(3) Indlela yokuhlola: ngokuhlola ngamehlo nokuhlola ngesandla, hlola bona ingabe kukhona na amaphutha abonakalako ebusweni bevalvu, hlola bona igama nelwazi lokuhlonza lilungile na.
2. Ukulinganisa ubukhulu
(1) Okuqukethwe kokuhlola: Linganisa ubukhulu obuqakathekileko bevalvu, kufaka hlangana indawo yokuhlanganisa, ubude bomzimba wevalvu, ububanzi besiqu sevalvu, njll., ukuqinisekisa bona ihlangabezana neemfuneko zemidwebo yokuklama namazinga. (2) Amazinga: Amazinga weentjhabatjhaba afaka hlangana i-ASMEB16.10, i-ASME B16.5, i-ISO 5752, njll.; Amazinga we-China afaka hlangana i-GB/T 12221 (ubude besakhiwo sevalvu), i-GB/T 9112 (ubukhulu bokuhlanganisa i-flange), njll. (3) Indlela yokuhlola: Sebenzisa ama-calipers, ama-micrometers namanye amathulusi wokulinganisa ukulinganisa ubukhulu obuqakathekileko bevalvu ukuqinisekisa bona ihlangabezana neemfuneko zokuklama.

3. Ukuhlolwa kokusebenza kokuvala
(1) Ukuhlolwa kwegandeleleko: faka umfutho we-hydrostatic nofana umfutho we-static ku-valve, bese uhlola ukuvuza ngemva kokuyigcina isikhathi esithileko. (2) Ukuhlolwa kokuvaleka komoya onomfutho ophasi: Lokha ivalvu nayivaliweko, kufakwa igesi enomfutho ophasi ngaphakathi kwevalvu begodu ukuvuza kuyahlolwa. (3) Ukuhlolwa kwamandla wendlu: sebenzisa umfutho we-hydrostatic ophezulu kunomtjhini wokusebenza ku-valve ukuhlola amandla wayo wendlu nokujamelana nomfutho.
