Jacketed rwb thaiv tsev pob Valve: Lub zog txuag dej tswj kev daws teeb meem

Jacketed insulated pob valve yog ib hom valve nrog zoo rwb thaiv tsev thiab txias yam ntxwv. Nws txoj kab uas hla yog ua raws li cov yeeb nkab txoj kab uas hla, uas tuaj yeem txo qhov kub poob ntawm qhov nruab nrab hauv cov kav dej. Hom valve no tsuas yog siv rau hauv ntau lub tshuab xws li roj av, tshuaj lom neeg, metallurgical, kev tsim khoom, thiab khoom noj khoom haus, thiab yog siv los thauj cov viscosity siab tshaj tawm uas yuav solidify ntawm chav tsev kub.

Cov yam ntxwv ntawm jacketed insulated pob li qub feem ntau suav nrog cov ntsiab lus hauv qab no:

1. Cov dej tsis kam yog me me, thiab nws cov coefficient kuj sib npaug ntawm cov kav dej ntawm tib qhov ntev;

2. Cov qauv yooj yim, me me, thiab lub teeb yuag;

3. Tight thiab txhim khu kev qha, nrog zoo sealing kev ua tau zoo, yas yog dav siv los ua cov khoom siv sealing thiab kuj tau siv dav hauv lub tshuab nqus tsev;

4. Yooj yim rau kev khiav lag luam, ceev qhib thiab kaw, tsuas yog 90 ° kev sib hloov los ntawm kev qhib rau tag nrho kaw, yooj yim rau kev tswj chaw taws teeb;

5. Kev saib xyuas yooj yim, cov qauv pob valve yooj yim, thiab feem ntau txav tau lub nplhaib sib khi, ua rau kev tshem tawm thiab hloov tau yooj yim dua;

6. Thaum qhib tag nrho lossis kaw tag nrho, qhov chaw sib khi ntawm lub pob thiab lub rooj zaum valve raug cais tawm ntawm qhov nruab nrab. Thaum qhov nruab nrab hla dhau, nws yuav tsis ua kom yaig ntawm lub valve sealing nto;

7. Nws muaj ntau yam kev siv, nrog rau txoj kab uas hla ntawm ob peb millimeters mus rau ob peb meters, thiab tuaj yeem siv los ntawm lub tshuab nqus tsev mus rau qhov siab.

Cov qauv tsim, qhov ntev ntev, kev sib txuas flange siab ntsuas kub thiab tshuaj xyuas ntawm lub tsho insulated pob li qub ua raws li cov qauv xws li GB / T9113, JB / T79, JB / T9092, GB / T12221, GB / T12224, GB / T12237, GB / T13927 , AP1598, HG / T20592, EN1092, thiab lwm yam.

Cov khoom tseem ceeb ntawm lub tsho insulated pob li qub muaj xws li lub tsho (PTFE), lub rooj zaum valve (WCB), lub cev lub cev (WCB), lub nplhaib sib khi (PTFE, kev sib raug zoo polystyrene), pob (stainless hlau), valve qia (1Cr13), packing ( saj zawg zog graphite), thiab packing caj pas (WCB).

Zuag qhia tag nrho, jacketed insulated pob li qub yog ib hom valve nrog kev ua tau zoo, kev ua haujlwm yooj yim, thiab kev saib xyuas yooj yim. Lawv tau siv dav hauv ntau lub tshuab thiab yog qhov kev xaiv zoo tshaj plaws rau kev xa cov viscosity siab tshaj tawm.
