Okwu mmalite nke eriri BSP

Eriri BSP bụ mbiri nke British Standard Pipe Thread, na-ezo aka na eriri ọkpọkọ ọkọlọtọ Britain, nke bụ nke otu W.ma Eriri (BS84), eze n'akuku bụ 55°. Dị ka ọdịdị ahụ si dị, eriri BSP nwere ụdị abụọ: cylindrical Pipe thread BSPP (British Standard Pipe Parallel) na Taper Pipe thread BSPT (British Standard Pipe Taper).

BSPP inch cylindrical ọkpọkọ eri. A na-akpọ ụdị eriri ọkpọ ọzọ "conical pipe thread", nke bụ aha a na-ahụkarị na aha ọkọlọtọ na akwụkwọ ọgụgụ.

N'ihi akụkọ ihe mere eme, a na-akpọkwa BSPP aha ndị ọzọ. Ndị a na-ahụkarị bụ BSPF (British Standard Pipe Fitting), BSPM (British Standard Pipe Mechanical), PS (British Standard Pipe Straight), wdg. Mgbe e mesịrị, na mmalite nke ISO standardization, aha ndị a dị iche iche gbanwere site na mkpụrụedemede G dị mfe. bụ eriri G. Ya mere, a na-akpọ BSPP, BSPF, BSPM na PS ugbu a dị ka eriri G.

A na-akpọ G threadi, n'ihi na eri karịa ka e jibu ya na Gas, na Gas for Gas na bekee, ma ụfọdụ kwuru na G si German Gewinde (nke pụtara eri), na mgbakwunye, G na tube (Guan) na Chinese pinyin mbụ. leta nke otu, ya mere banyere mmalite nke G threadia, n'agbanyeghị nke echiche yiri ezi uche, Ọ bụ n'ezie a ndaba.

 

Eriri G, eriri ime na eriri dị n'èzí, eji maka njikọ anaghị emechi. Ụkpụrụ mmejuputa iwu bụ BSENISO228-1, ọkọlọtọ ochie bụ BS2779, kagburu.

BSPT inch taper thread, nke a makwaara dị ka PT thread, na-eji naanị maka mkpokọta akara njikọ. BSPT ochie ọkọlọtọ bụ BS21, na na ọhụrụ ọkọlọtọ BSEN10226-1, dochie R eri. Ya mere R thread bụ aha izugbe nke BSPT na PT thread.

Akwụkwọ ozi R na eri R si na German rohr (German maka "tube"). Nri R bụ n'ezie usoro, Rp nkịtị, Rs, Rc, R1 na R2. Nkọwa dị ka ndị a:

Rp-inch akara cylindrical eriri ime

Rs-inch akara cylindrical mpụta eri

eri ime nke rc-inch akara taper

R1-inch akara taper mpụga eri, eji Rp, ntụgharị Rp/R1 "kọlụm/cone" eri.

R2-inch nke agbachiri eri mpụga tapered maka ojiji na Rc, Rc/R2 "taper/taper" eri

Enwere ike ịhụ na a na-ekewa eriri ọkpọkọ nke Britain n'ozuzu n'ime eriri cylindrical na eriri ọkpọkọ.

Nhazi nke eriri eriri cylindrical (Rp) maka akara bụ otu ihe ahụ nke eriri ọkpọkọ a na-emechighị emechi, mana ọdịiche dị na nkenke nke eri ahụ. The sealing tapered pipe thread (R) na-atụgharị gaa na taper nke 1:16 na ndabere nke eriri cylindrical.

 

General sealing na cylindrical pipe thread (Rp) akara mmetụta bụ site na ofụri eri ma ọ bụrụ na ọ dị mkpa tinye sealing filler (dị ka: ptfe sealing teepu), kama akara na a cylindrical ọkpọkọ eri akara mmetụta (G) bụ site na gburugburu nsọtụ. nke njikọ eriri ma ọ bụ ngwaọrụ ejiri akara ya (dịka: ụdị O akara mgbanaka).

Tụkwasị na nke ahụ, e nwere ọdịiche dị na iji na imewe ndidi nke a na-ejikọta ọnụ na eriri ọkpọkọ na-adịghị ekpuchi.

N'ezie, ọtụtụ n'ibu nhazi ụlọ ọrụ na nhazi nke BSP eri na-emekarị na-ezute eri mgbanaka plọg nlele nlele bụ ruru eru ma ọnụ bụ ikpe nke ogbenye akara isi ihe kpatara mgbagwoju anya nke akara Rp esịtidem eri na-abụghị sealing G esịtidem eri.
