Na China ochie, Shanghai bụ ebe mbụ na-emepụta valves na China.

Igwe mmiri teapot bụ ụdị ọkpa ọla kọpa nke nkedo. Ọ bụ onye nrụpụta valvụ mbụ na China mara ugbu a. Na 1919, Deda (Shengji) Hardware Factory (onye bu ụzọ nke Shanghai Transmission Machinery Factory) malitere site na obere igwe kwụ otu ebe wee malite imepụta cocks ọla kọpa dị obere dayameta, valves globe, valves ọnụ ụzọ na ọkụ ọkụ. Nrụpụta nke valvụ ígwè nkedo malitere na 1926, nke nwere oke n'ọnụ ọgụgụ nke NPS6 (na sentimita, NPS1 = DN25.4). N'ime oge a, ụlọ ọrụ ngwaike dị ka Wang Yingqiang, Dahua, Lao Demao na Maoxu meghekwara imepụta valves. Mgbe nke ahụ gasịrị, n'ihi mmụba nke ọchịchọ nke valvụ mmiri n'ahịa, ụlọ ọrụ ngwaike ọzọ, ụlọ ọrụ ígwè, ụlọ ọrụ ájá (nkedo) na ụlọ ọrụ igwe meghere iji rụpụta valves n'otu n'otu.

Na 1935, factory guzosie ike a nkwonkwo venture na Xiangfeng Iron Pipe Factory na Xiangtai Iron Co., Ltd. shareholders na-ewu Daxin Iron Factory (onye bu ụzọ nke Shanghai Bicycle Factory), na 1936 Mezuo na tinye n'ime mmepụta, e nwere fọrọ nke nta 100 ọrụ. , ya na 2.6 zhang (1 zhang≈3.33m) lathes na ebuli akụrụngwa, tumadi na-emepụta ụlọ ọrụ mmepụta ihe na ngwa Ngwuputa, nkedo mmiri ọkpọkọ na nkedo ígwè valvụ, ọnụ ọgụgụ nke valvụ bụ NPS6 ~ NPS18, na Ọ nwere ike chepụta na inye zuru ezu tent nke valves maka mmiri osisi, na A na-ebupụ ngwaahịa ndị ahụ na Nanjing, Hangzhou na Beijing. Mgbe “August 13” ndị mwakpo Japan weghaara Shanghai na 1937, ọkụ ogbunigwe ndị Japan bibiri ọtụtụ ihe ọkụkụ na akụrụngwa dị na ụlọ ọrụ ahụ. N'afọ sochirinụ mụbara isi obodo ma maliteghachi ọrụ.
