三阀组的安装、拆卸及使用方法
Three Valves mounting, disassembly and method of application
安装 Mounting
拆卸 Disassembly
1. 正常使用差压表必须配三阀组或五阀组以保护差压表正常工作。
2. 差压表和三阀组用两个索母紧固。索母和差压表接头密封面应加四氟垫片。
3. 装有三阀组的差压表在使用前必须把中间阀门打开,并把正压阀门和负压阀门打
开。(当 P+和 P- 任意的压力**入时,中间阀门能起到平衡差压表两腔体内的压
力的作用,以免打坏差压表。)
4. 当P+、P-的压力正常进入三阀组后,再关闭中间阀门使差压表正常工作。如差
压表表针有轻微离零属正常,只需把表针调到零位即可(注意必须用肥皂水检验所
有密封口是否泄露,如有泄露必须紧固。)
5. 差压表有后背板式安装(如图)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. 首先打开三阀组的中间阀门。并打开正压和负压阀门(正压负压阀门原始为打开)
2. 关闭总进气的两个阀门。(在设备的主管道上)
3. 拆下更换仪表(卸两个索母)注意用扳子卡住差压表的接头,只拆三阀组上的上
索母。先松开一点放空压力,再把卡到管子上的卡子螺母松掉,并把卡子拿下。
4. 再把三阀组上的两个索母慢慢松开把差压表取下。 (注意一定要两个索母同时松)
5. 把新表装上的方法同上面安装方法**换上两个新的四氟垫(确保不漏)
6. 把卡子卡好
7. 先开总开关(两个),再关上差压表三阀组中间的阀门(新接口用肥皂水试漏)。
8. 两分钟后把差压表表针调到零位。(如没有轻微离零不用调整)
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

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:在装表或卸表时,必须保证中间阀门和P+、P-两个阀门全部开启,以确保仪表能正常使用。
