Valvewaa badeecad muhiim u ah mishiinada guud. Waxaa lagu rakibay tuubooyin ama qalab kala duwan si loo xakameeyo socodka dhexdhexaadka ah iyadoo la beddelayo aagga kanaalka ee valve. Shaqadiisu waa: isku xidhka ama gooya dhexdhexaadinta, ka ilaali dhexdhexaadinta inay dib u socoto, hagaajiso xuduudaha sida cadaadiska dhexdhexaadka ah iyo socodka, beddelka jihada dhexdhexaadka, kala qaybi dhexdhexaadinta ama ka ilaali dhuumaha iyo qalabka cadaadiska xad-dhaafka ah, iwm.
Waxaa jira noocyo badan oo alaabooyinka valve, kuwaas oo loo qaybiyaywaalka iridda, globe valve,hubi waalka, waalka kubbadda,balanbaalis, waalka fur, waalka diaphragm, waalka badbaadada, waalka nidaaminaya (laabka kantaroolka), waalka ceejinta, cadaadiska yareeya waalka iyo dabinada, iwm.; Sida laga soo xigtay maaddada, waxay u qaybsantaa daawaha naxaasta, birta kabka, birta kaarboon, birta daawaha, birta austenitic, birta ferritic-austenitic dual-phase steel, alloy-ku-salaysan nikkel, alloy titanium, balaastiig injineernimada iyo balaastikada dhoobada, iwm. , waxaa jira valves gaar ah sida valves cadaadis ultra-sare, vacuum valves, valves station power, valves for pipelines iyo pipelines, valves for industry nuclear, valves for maraakiibta iyo valves cryogenic. Baaxadda cabbirada waalka, cabbirka magaca ah laga bilaabo DN1 (cutubka mm) ilaa DN9750; Cadaadis magac-u-yaal ah oo ka yimaada ultra-vacuum of 1× 10-10 mmHg (1mmHg = 133.322Pa) ilaa cadaadiska aadka u sarreeya ee PN14600 (cutubka 105 Pa); Heerkulka shaqadu wuxuu u dhexeeyaa heerkulka aadka u hooseeya ee -269℃heerkulka aadka u sarreeya ee 1200℃.
Alaabta Valve waxaa si weyn loogu isticmaalaa qaybaha kala duwan ee dhaqaalaha qaranka, sida saliidda, gaaska dabiiciga ah, saliidda iyo gaaska sifaynta iyo habaynta gaadiidka iyo dhuumaha, alaabta kiimikada, daawooyinka iyo hababka wax soo saarka cuntada, tamarta biyaha, tamarta kulaylka iyo nidaamka wax soo saarka tamarta nuclear; Noocyada kala duwan ee valves ayaa si weyn loogu isticmaalaa kuleylinta iyo nidaamyada korontada, hababka wax soo saarka biraha, hababka dareeraha ee maraakiibta, baabuurta, diyaaradaha iyo mashiinada isboortiga ee kala duwan, iyo waraabka iyo nidaamka dheecaanka dhul beereed. Intaa waxaa dheer, dhinacyada tignoolajiyada cusub sida difaaca iyo hawada hawada, valves kala duwan oo leh sifooyin gaar ah ayaa sidoo kale loo isticmaalaa.
Alaabooyinka Valve waxay ku xisaabtamaan qayb weyn oo ah alaabta farsamada. Marka loo eego tirakoobka wadamada shisheeye ee ku horumaray warshadaha, qiimaha wax soo saarka ee valves-ku wuxuu xisaabiyaa qiyaastii 5% qiimaha wax soo saarka dhammaan warshadaha mishiinnada. Marka loo eego tirakoobyada, warshad dhaqameed oo tamarta nukliyeerka ah oo ka kooban laba milyan oo kilowatts waxay leedahay qiyaastii 28,000 oo ah valves la wadaago, kuwaas oo ku saabsan 12,000 oo ah jasiiradaha nuklearka. Qalab casri ah oo batroolka kiimikaad ah ayaa u baahan boqollaal kun oo tufaaxyo kala duwan ah, maalgelinta valves-ku guud ahaan waxay ka dhigan tahay 8% ilaa 10% wadarta maalgashiga qalabka.
Xaaladda guud ee warshadaha waalka ee Shiinaha hore
01 Meesha ay ku dhalatay warshadda waalka ee Shiinaha: Shanghai
Shiinaha qadiimka ah, Shanghai waxay ahayd meeshii ugu horreysay ee laga soo saaro valves gudaha Shiinaha. Sannadkii 1902dii, Pan Shunji Copper Workshop, oo ku yaalla Waddada Wuchang, Degmada Hongkou, ee Shanghai, ayaa bilaabay inay gacanta ku samayso qaybo yaryar oo tubooyinka shaaha ah. Tubada dheriga shaaha waa nooc cows naxaas ah oo la shubay. Waa soo saaraha valve ee ugu horreeya Shiinaha oo la yaqaan ilaa hadda. Sannadkii 1919kii, Deda (Shengji) Warshada Hardware (hore u ahaa Warshada Mashiinnada Gudbinta ee Shanghai) waxay ka bilowday baaskiil yar waxayna bilawday inay soo saarto cocks naxaas ah oo dhexroor yar, valves globe, valves-ka albaabka iyo biyaha dabka. Soo-saarista tuubooyinka birta ah waxay bilaabantay 1926-kii, iyadoo ugu badnaan cabbirka magaca NPS6 (incis, NPS1 = DN25.4). Inta lagu jiro muddadan, warshadaha qalabka sida Wang Yingqiang, Dahua, Lao Demao iyo Maoxu ayaa sidoo kale furay si ay u soo saaraan valves. Intaa ka dib, kororka baahida loo qabo tubooyinka tuubooyinka ee suuqa, qayb kale oo ka mid ah warshadaha qalabka, warshadaha birta, warshadaynta ciidda (dharka) iyo warshadaha mishiinnada ayaa la furay si ay u soo saaraan valves midba midka kale.
Kooxda wax soo saarka valve ayaa laga sameeyay aagagga Zhonghongqiao, Waihongqiao, Daming Road iyo Changzhi Road ee Degmada Hongkou, Shanghai. Waqtigaas, noocyada ugu iibsiga badan ee suuqyada gudaha waxay ahaayeen "Horse Head", "Saddex 8", "Saddex 9", "Double Coin", "Birta Birta ah", "Kubadda Digaaga" iyo "Eagle Ball". Naxaasta kabka ah ee cadaadiska hooseeya iyo alaabada kabka birta ah ayaa inta badan loo isticmaalaa tuubooyinka tuubooyinka dhismaha iyo tas-hiilaadka fayadhowrka, iyo qadar yar oo kabka birta ah ayaa sidoo kale loo isticmaalaa qaybta warshadaha dharka fudud. Warshadahani aad bay u yar yihiin miisaan ahaan, oo leh tignoolajiyada dib u dhaca, qalabka dhirta fudud iyo wax soo saarka waalka oo hooseeya, laakiin waa meesha ugu horraysa ee ay ku dhashaan warshadaha waalka ee Shiinaha. Ka dib, ka dib markii la aasaasay Ururka Dhismaha Hardware ee Shanghai, kuwan soo saarayaasha valve waxay ku biireen ururka midba midka kale waxayna noqdeen kooxda biyaha. xubin.
02Laba warshadood oo waalka soo saara oo baaxad weyn
Bilowgii 1930kii, Warshada Mashiinnada ee Shanghai Shenhe waxay soo saartay albaabka kabka birta cadaadiska hooseeya ee ka hooseeya NPS12 ee shaqooyinka biyaha. In 1935, warshadda aasaasay ganacsi wadajir ah la Xiangfeng Iron Pipe Factory iyo Xiangtai Iron Co., Ltd. shareholders si ay u dhisaan Daxin Iron Warshada (hore ee Shanghai Baaskiilada Warshada), in 1936 Dhammaystirka iyo saaray wax soo saarka, waxaa jira ku dhawaad 100 shaqaale. , oo leh 2.6 zhang (1 zhang≈3.33m) qalabka wax lagu dhejiyo iyo kuwa wax lagu qaado, inta badan soo saara qalabka warshadaha iyo macdanta, tuubooyinka birta birta ah iyo tuubooyinka birta ah, cabbirka magaca ee waalka waa NPS6 ~ NPS18, wuxuuna naqshadayn karaa oo uu siin karaa qaybo dhammaystiran oo valves ah oo loogu talagalay dhirta biyaha, iyo Alaabooyinka waxaa loo dhoofiyaa Nanjing, Hangzhou iyo Beijing. Ka dib "August 13" duullaankii Japan ayaa qabsaday Shanghai 1937, inta badan warshaddii iyo qalabkii warshadda waxaa burburiyay madaafiicda Japan. Sannadkii xigay ayaa korodhay raasamaal oo shaqadii dib u bilaabay. NPS14 ~ NPS36 waxay tuurtay albaabada albaabka birta, laakiin niyad jab dhaqaale, ganacsi caajis ah, iyo caydhnimo awgeed, ma aysan awoodin inay ka soo kabtaan ilaa habeenkii la aasaasay Shiinaha Cusub.
Sannadkii 1935, shan saamileyaal oo uu ku jiro Li Chenghai, oo ah ganacsade qaran, ayaa si wadajir ah u aasaasay Shenyang Chengfa Iron Warshada (hore u ahaa Warshada Tieling Valve) ee Shishiwei Road, Degmada Nancheng, Shenyang City. Hagaajinta oo soo saar valves. Sannadkii 1939kii, warshadda waxa loo raray Beierma Road, degmada Tiexi si loo balaadhiyo, waxaana la dhisay laba aqoon-is-weydaarsi oo waaweyn oo loogu talagalay shubista iyo mishiinada. Sannadkii 1945kii, waxa ay kortay ilaa 400 oo shaqaale ah, wax-soo-saarkeeda ugu waaweynina waxa ay ahaayeen: kuleyliyayaasha waaweyn, tuubooyinka naxaasta ah, iyo albabka dhulka hoostiisa mara ee kabka birta ah oo cabbirkoodu ka hooseeyo DN800. Shenyang Chengfa Iron Factory waa warshad soo saarta waalka oo u halgamaysa sidii ay ugu noolaan lahayd Shiinaha hore.
03 Warshadaha waalka ee gadaasha
Intii lagu guda jiray dagaalkii ka dhanka ahaa Jabbaan, shirkado badan oo ku yaal Shanghai iyo meelo kale ayaa u guuray koonfur-galbeed, sidaas darteed tirada shirkadaha Chongqing iyo meelaha kale ee aagga dambe ayaa kor u kacay, warshaduhuna waxay bilaabeen inay horumaraan. Sannadkii 1943-kii, Warshada Mashiinnada ee Chongqing Hongtai iyo Warshada Mashiinnada Huachang (labadaba warshadood waxay ahaayeen kuwii ka horreeyay ee Chongqing Valve Factory) waxay bilaabeen inay dayactiraan oo ay sameeyaan qaybo tuubooyin ah iyo tuubooyinka cadaadiska hooseeya, kuwaas oo door weyn ka ciyaaray horumarinta wax soo saarka dagaalka ee gadaal iyo xallinta rayidka. alwaaxyada. Ka dib guushii Dagaalkii Jabbaan, Warshada Lisheng Hardware, Bulshada Warshadaha ee Zhenxing, Warshada Hardware ee Jinshunhe iyo Warshada Hardware ee Qiyi ayaa si isdaba joog ah u furay si ay u soo saarto baallayaasha yaryar. Ka dib markii la aasaasay Shiinaha Cusub, warshadahan waxaa lagu daray Chongqing Valve Factory.
Waqtigaas, qaarsoo saarayaasha waalkaShanghai sidoo kale waxay tagtay Tianjin, Nanjing iyo Wuxi si ay uga dhisto warshado lagu dayactiro oo lagu sameeyo valves. Qaar ka mid ah warshadaha qalabka, warshadaha birta, warshadaha mishiinada ama maraakiibta ee Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou iyo Guangzhou ayaa sidoo kale ku hawlanaa hagaajinta iyo samaynta qaar ka mid ah tubooyinka tuubooyinka.
