Kev Paub Txog Tsis-metallic Expansion Joints

Non-metallic expansion pob qij txha

Non-metallic expansion pob qij txhakuj tseem hu ua non-metallic compensators thiab fabric compensators, uas yog ib hom kev them nyiaj. Non-metallic expansion sib koom cov ntaub ntawv yog cov ntaub fiber ntau, roj hmab, cov ntaub ntawv kub thiab lwm yam. Nws tuaj yeem them nyiaj rau kev co ntawm cov kiv cua thiab cov pa cua thiab qhov deformation ntawm cov kav dej.

Daim ntawv thov:

Non-metallic expansion pob qij txha tuaj yeem them rau axial, lateral thiab angular cov lus qhia, thiab muaj cov yam ntxwv ntawm tsis muaj thrust, yooj yim bearing tsim, corrosion kuj, kub tsis kam, suab nrov txo thiab vibration txo, thiab tshwj xeeb tshaj yog haum rau cov cua kub ducts thiab pa taws. thiab plua plav ducts.

Fabric compensator

1 Kev them nyiaj rau kev nthuav dav thermal: Nws tuaj yeem them nyiaj rau ntau yam kev qhia, uas yog qhov zoo dua li cov khoom siv hlau uas tuaj yeem them rov qab rau hauv ib txoj kev xwb.

2. Kev them nyiaj yug ntawm kev teeb tsa yuam kev: Vim tias qhov kev ua yuam kev hauv qhov system tsis tuaj yeem zam tau hauv cov txheej txheem ntawm kev sib txuas ntawm cov kav dej, lub fiber ntau compensator tuaj yeem them nyiaj zoo dua rau kev teeb tsa yuam kev.

3 Kev txo suab nrov thiab kev vibration txo: Cov ntaub fiber ntau (silicone daim ntaub, thiab lwm yam) thiab thermal rwb thaiv tsev paj rwb lub cev muaj lub luag haujlwm ntawm lub suab nqus thiab kev co kev sib cais, uas tuaj yeem txo cov suab nrov thiab kev vibration ntawm boilers, kiv cua thiab lwm yam tshuab.

4 Tsis muaj qhov thim rov qab: Vim tias cov khoom tseem ceeb yog fiber ntau, nws tsis muaj zog. Kev siv cov khoom siv fiber ntau ua kom yooj yim rau kev tsim, zam kev siv cov kev txhawb nqa loj, thiab txuag tau ntau yam khoom thiab kev ua haujlwm.

5. Kev kub siab zoo thiab kev tiv thaiv corrosion: Cov khoom siv fluoroplastics thiab silicone tau xaiv muaj qhov kub thiab txias tsis kam thiab corrosion kuj.

6. Kev ua haujlwm zoo sealing: Nws muaj qhov ua tiav kev tsim khoom thiab kev sib dhos, thiab cov khoom siv fiber ntau tuaj yeem ua kom tsis muaj paug.

7. Lub teeb yuag, qauv yooj yim, yooj yim installation thiab txij nkawm.

8. Tus nqi qis dua cov khoom siv hlau

 Basic qauv

1 tawv

Daim tawv nqaij yog lub ntsiab expansion thiab contraction lub cev ntawm non-hlau expansion sib koom ua ke. Nws yog tsim los ntawm ntau cov khaubncaws sab nraud povtseg ntawm silicone roj hmab los yog high-silica polytetrafluoroethylene nrog kev ua tau zoo heev thiab alkali-dawb iav ntaub plaub. Nws yog ib tug high-strength sealing composite khoom. Nws txoj haujlwm yog txhawm rau nqus qhov nthuav dav thiab tiv thaiv cov pa tawm ntawm huab cua thiab dej nag.

2 stainless hlau hlau mesh

Lub stainless hlau xaim mesh yog cov hauv ob sab phlu ntawm non-metallic expansion sib koom ua ke, uas tiv thaiv cov sundries nyob rau hauv lub circulating nruab nrab los ntawm kev nkag mus rau hauv expansion sib koom tes thiab tiv thaiv cov thermal rwb thaiv tsev cov ntaub ntawv nyob rau hauv lub expansion sib koom ua ke los ntawm kev khiav tawm sab nraud.

3 rwb thaiv tsev paj rwb

Thermal rwb thaiv tsev paj rwb coj mus rau hauv tus account lub dual zog ntawm thermal rwb thaiv tsev thiab huab cua nruj ntawm non-metallic expansion pob qij txha. Nws yog tsim los ntawm iav fiber ntau daim ntaub, siab silica daim ntaub thiab ntau yam thermal rwb thaiv tsev paj rwb felts. Nws qhov ntev thiab qhov dav yog zoo ib yam nrog cov tawv nqaij sab nrauv. Zoo elongation thiab tensile zog.

4 Rwb thaiv tsev muab tub lim

Thermal rwb thaiv tsev muab tub lim txheej yog lub ntsiab lav rau thermal rwb thaiv tsev ntawm non-metallic expansion pob qij txha. Nws yog tsim los ntawm cov ntaub ntawv kub resistant xws li multi-layer ceramic fibers. Nws cov tuab tuaj yeem txiav txim siab los ntawm kev hloov pauv hluav taws xob raws li qhov ntsuas kub ntawm qhov nruab nrab thiab cov thermal conductivity ntawm cov khoom kub resistant.

5 racks

Lub thav duab yog contour bracket ntawm non-metallic expansion pob qij txha kom muaj zog txaus thiab rigidity. Cov khoom siv ntawm lub thav duab yuav tsum tau hloov mus rau qhov kub ntawm qhov nruab nrab. Feem ntau ntawm 400. Siv Q235-A 600 hauv qab C. Saum C yog ua los ntawm cov hlau tsis muaj steel lossis cov hlau tsis muaj cua sov. Lub thav duab feem ntau muaj flange nto uas phim cov kab txuas txuas.

6 bez

Lub baffle yog coj tus khiav thiab tiv thaiv cov thermal rwb thaiv tsev txheej. Cov khoom siv yuav tsum ua raws li qhov nruab nrab kub. Cov ntaub ntawv yuav tsum yog corrosion thiab hnav-resistant. Lub baffle yuav tsum tsis txhob cuam tshuam qhov kev hloov pauv ntawm qhov sib koom ua ke.
