Kwimisebenzi eqhelekileyo, izixhobo ezininzi zisetyenziswa rhoqo ukunceda ii-differential pressure transmitters ukuba zisebenze ngokufanelekileyo. Esinye sezixhobo ezibalulekileyo yi-valve manifold. Injongo yokusetyenziswa kwayo kukukhusela i-sensor kumonakalo wecala elinye phezu koxinzelelo kunye nokwahlula i-transmitter kwinkqubo ngelixa ilungiswa, ilinganiswa okanye itshintshwa. I-3-valve manifold eqhelekileyo ibandakanya i-equalizing valve enye kunye nee-block valves ezimbini ezihambelana necala eliphezulu neliphantsi loxinzelelo lwe-transmitter. Zonke ii-valve zidityaniswe kwi-metal block edibanisa igumbi le-transmitter ngokudibanisa inkqubo.
Emva kokuba ukufakela kugqityiwe, ukuqalisa umlinganiselo, vula ivalve yokulinganisa kuqala, emva koko uvule iivalve zebhloko kwindawo ephantsi kunye noxinzelelo oluphezulu ngokulandelelana. Lindela de uxinzelelo kwimigca luzinzile, vala ivalve yokulinganisa ngokuqinileyo kwaye ushiye iivalve zebhloko zivulekile, emva koko isixhobo silungele ukudityaniswa koxinzelelo okanye ukubonwa kokuhamba. Ukwahlula isidluliseli, vala ivalve yebloko yecala eliphezulu, vula ivalve yokulinganisa kwaye uvale ivalve yebloko ephantsi yoxinzelelo ekugqibeleni ukuze uqiniseke ukuba uxinzelelo olushiyekileyo kwigumbi lokuhambisa lugcinwa lusezantsi kangangoko kunokwenzeka. Ekugqibeleni, vula izifakelo zokopha ukuze ucime uxinzelelo lwentsalela emva kokuba isixhobo sicinyiwe kwinkqubo.
Olunye uhlobo oluqhelekileyo lwe-DP transmitter yi-5-valve manifold, edibanisa iivalve ezimbini ze-morel bleed ngesiseko se-3-valve. Iivalvu ezongezelelweyo ezakhelwe ngaphakathi zivumela uxinzelelo lwentsalela ukuba lungene kwindawo ekude endaweni yokuba kufutshane necala legumbi.
Njengoko kukhankanyiwe ngasentla, uxinzelelo oluphakathi oluqokelelweyo lwentsalela kufuneka lukhutshwe phambi kokuba kususwe isithutha se-DP kwinkonzo. Ezinye iintlobo zophindaphindo zinokubonelela ngeevalvu zokopha emsebenzini kodwa eyona ndlela ixhaphakileyo kukufakela ukopha okufakwe kwicasi yegumbi lokuhambisa ngoqhagamshelo lomsonto. Khulula kwaye ususe iiplagi, kwaye uxinzelelo oluphakathi oluseleyo luya kuphuma kwii-orifices.
Ekugqibeleni, kuyaphawuleka ukuba ii-DP transmitters zihlala zifakwe kwizibiyeli. Isibiyeli sokunyuswa kwemibhobho yenzelwe ukunika indlela ezinzileyo yokuncamatheliswa kwee-DP transmitters kwindawo yokusebenza. Ubukhulu becala yenziwe nge-U-bolt kunye nepleyiti ethe ngqo okanye eyi-L.
Njengomvelisi wesixhobo esinamava obonelela ngesona sisombululo sisesona sisetyenzisiweyo somzi-mveliso, iWangYuan iyakwazi ukuzalisekisa naziphi na iimfuno zoncedo lwethuIimveliso zothotho lweWP3051. Ukuba unawo nawaphi na amathandabuzo okanye imfuno kwizincedisi ezingentla nceda uzive ukhululekile ukuqhagamshelana nathi.
