JX-8100 steam and water sampling and analyzing device

The soda water sampling device is used for the continuous continuous sampling of water and steam by the firepower (thermal) electric system, and the chemical analysis and monitoring of the sample by the supporting instrument and the microcomputer 。

The main technical parameters

1. Working pressure of high pressure pipeline system: ≤32MPa

2, sample outlet temperature: cooling water temperature +1.5 ° C

3. Sample outlet flow: 0~3500ml/min

4. Sample outlet pressure: 0.1~0.4MPa

Low temperature sampling rack features

1. Open-closed cabinet structure after front closure,  chemical instruments are fixed on the panel by mosaic.

2, low-pressure pipelines, parts, detachable meter transmitters are arranged mklmlm on the back of the skeleton.

3. Designed practical and feasible reagent racks for different instruments. This design is greatly welcomed by chemical operators in power plants.

4. The internal pedals, pipes and wires of the skeleton are arranged in layers.

5. The profile is made by bending cold-rolled steel plate.

High temperature sewage system features

After the sample water enters the sampling system from the sampling device, one of the sample waters is directly discharged to the high temperature and high pressure sewage main pipe. The high pressure sewage pipe is strictly prohibited from communicating with the low pressure sewage pipe to prevent the high pressure sewage from flowing into the low pressure pipeline. 

High temperature and high pressure shut-off valve features

1. Based on the introduction of technology, the company developed a stainless steel stop valve resistant to high temperature and high pressure.

2. The valve body is made of high temperature resistant OCr18Ni12Mo2Ti material, the valve flap is sealed with imported cobalt-based alloy head, special flexible graphite filler and suitable heat treatment method, which solves the intergranular corrosion of stainless steel at high temperature and the same material. A series of problems such as different thermal expansion coefficients between the bite and the thread paying ensure that the valve has good high temperature and high pressure resistance, strong anti-scour ability, long service life and small opening torque.

Pressure reducing valve features

1. Threaded channel type pressure reducing valve has 9 models from GF1 to GF9. The common type is GF8, which is called adjustable thread channel pressure reducing valve. GF9 is called automatic constant current reducing valve, which is suitable for peaking unit .

2. After the sample water flows through GF8, the pressure drops below 0.4 MPa.

3, under the pressure of 3MPa, you can get 50ml / min starting flow.

4, the adjustment handle, the switching torque is less than 0.05 cattle * m
