三閥組的安裝、拆卸及使用方法
Three Valves mounting, disassembly and method of application
安裝 Mounting
拆卸 Disassembly
1. 正常使用差壓表必須配三閥組或五閥組以保護(hù)差壓表正常工作。
2. 差壓表和三閥組用兩個(gè)索母緊固。索母和差壓表接頭密封面應(yīng)加四氟墊片。
3. 裝有三閥組的差壓表在使用前必須把中間閥門打開,并把正壓閥門和負(fù)壓閥門打
開。(當(dāng) P+和 P- 任意的壓力**入時(shí),中間閥門能起到平衡差壓表兩腔體內(nèi)的壓
力的作用,以免打壞差壓表。)
4. 當(dāng)P+、P-的壓力正常進(jìn)入三閥組后,再關(guān)閉中間閥門使差壓表正常工作。如差
壓表表針有輕微離零屬正常,只需把表針調(diào)到零位即可(注意必須用肥皂水檢驗(yàn)所
有密封口是否泄露,如有泄露必須緊固。)
5. 差壓表有后背板式安裝(如圖)和立管固定方法。(管卡子卡到管子上)。
1. Use differential gauge must fit out three valves in order to insure it’s normal
working.
2. The differential gauge and there valves are connected by two nuts tightly, nuts
and socket are with PTFEspacer.
3. Open the middle valve, negative pressure valve and positive pressure valve
before use the differential gauge, when either of P- or P+ input, the middle valve can
have equilibrium activity, and avoid to damage the gauge.
4. When P- and P+ normal input the three valves, the close the middle valve, to
make the gauge works right. If the gauge’s pointer is not at zero, please adjust it
to zero (note must use soap water to inspect the seal, if has leak, please tight.)
5. The differential pressure gauge has back plate mounting (see the chart) and
standpipe fixed (the pipe with clamp).
1. 首先打開三閥組的中間閥門。并打開正壓和負(fù)壓閥門(正壓負(fù)壓閥門原始為打開)
2. 關(guān)閉總進(jìn)氣的兩個(gè)閥門。(在設(shè)備的主管道上)
3. 拆下更換儀表(卸兩個(gè)索母)注意用扳子卡住差壓表的接頭,只拆三閥組上的上
索母。先松開一點(diǎn)放空壓力,再把卡到管子上的卡子螺母松掉,并把卡子拿下。
4. 再把三閥組上的兩個(gè)索母慢慢松開把差壓表取下。 (注意一定要兩個(gè)索母同時(shí)松)
5. 把新表裝上的方法同上面安裝方法**換上兩個(gè)新的四氟墊(確保不漏)
6. 把卡子卡好
7. 先開總開關(guān)(兩個(gè)),再關(guān)上差壓表三閥組中間的閥門(新接口用肥皂水試漏)。
8. 兩分鐘后把差壓表表針調(diào)到零位。(如沒有輕微離零不用調(diào)整)
1. Open the middle valve, negative pressure valve and positive pressure valve
(negative pressure valve and positive pressure valve original state is open).

② Three Valves
③ negative pressure valve
④ positive pressure valve
⑤ middle valve
⑥ nuts
① Upper nut
② Middle Valve
2. Close these two input valves (on the main pipe of equipment).
3. Discharge instrument (discharge two nuts), use spanner lock the socket of gauge, and just discharge the nuts on three valves.
Discharge pressure, then put off the nuts and clamp.
4. Screw down the two nuts and take down the differential pressure gauge (note screw down these two nuts together)
5. Then install the new gauge (same as mounting method), change two spacers to ensure it will not leak.
6. Fix the clamp.
7. Open main switch (two), then close the middle valve. (use soap water to inspect leak)
8. Two minutes later, set the pointer at zero (if it does not out off zero, you needn’t to adjust).
注:在裝表或卸表時(shí),必須保證中間閥門和P+、P-兩個(gè)閥門全部開啟,以確保儀表能正常使用。
