ʻO nā kiwi polū kila kila ua maheleia i nā pahupaʻa honua kila kila a nā kiwi poʻo honua kila kuhili ʻole, hoʻohana maʻamau i nā manawa kiʻekiʻe a me ke kiʻekiʻe (150lb-800lb, 1500LB, 2500LB), a me nā manawa kiʻekiʻe a me nā haʻahaʻa haʻahaʻa (-196 ℃ ~ 700 ℃), ʻoi aku ka ikaika kiʻekiʻe a me nā pono mechanical maikaʻi aʻe e hoʻokō ai i ke kaomi kiʻekiʻe. koi. Akā i kaupalena ʻia i ke kaʻina hana forging, pili pinepine wale i ka liʻiliʻi a me ka nui liʻiliʻi (1/2 ", 3/4", 1 ", 1-1/4", 1-1/2 ", 2, 2-1/2 “, 3 “a me 4″). Hiki i ka Valve Operation ke manual, bevel gear, pneumatic actuator, electric actuator, hydraulic actuator, pneumatic-hydraulic, electro-hydraulic.

ʻO nā mea maikaʻi o ka hui ʻo Newsway Valve i hana ʻia e like me kēia:

1. Forged kila globe kiwikā apono pumi iho-tightening sila, a me na welau elua o ke kino lala lala paipu ua welded.

2. Forged kila globe valve valve noho, valve disc sealing surface is made of cobalt-based cemented carbide plasma spray welding, wear resistance, high abrasion resistance.

3. Hoʻomaʻamaʻa ʻia ke ʻano o ka valve me ka corrosion resistance nitriding, he maikaʻi ke kūpaʻa ʻana a me ke kūpaʻa abrasion.

4 i ka wehe 'ana a me ka pani kaʻina hana, ma muli o ka kiwikā disc i loko o ke kino kiwikā hoʻopaʻa 'ilina friction mea liʻiliʻi, a komo ke kū'ē.

5. ʻO ka maʻamau he hoʻokahi wale nō maka sila ma ke kino valve a me ka disc, no laila ʻoi aku ka maikaʻi o ke kaʻina hana no ka mālama ʻana.

Pono e nānāʻia ka valve ma mua o ka hoʻokomoʻana, aʻo ke kūlana hoʻolālā valve e like me ka API 602 kūlana honua o kēia manawa. Ma ka ho'āʻo ikaika,ʻo ka ho'āʻo ho'āʻo he 1.5 mau manawa o ke kaomi nominal, aʻo ka lōʻihiʻaʻole i emi iho ma mua o 5min. Pono e hoʻomaʻamaʻa ʻia ka pūpū valve a me ka hoʻopili ʻana me ka ʻole o ka leakage. ʻO ka hoʻāʻo hoʻopaʻa ʻana, ʻo ke kaomi hoʻāʻo he 1.1 mau manawa o ke kaomi nominal; Pono ke kaomi ho'āʻo i ka manawa lōʻihi o ka hoʻāʻo ʻana i nā KOINA o ka maʻamau API 598, me ka ʻole o ka leakage ma ka ʻili hoʻopaʻa disc e like me ke kūpono.
