I. Product overview

WINFOSS-A21-3I series SF6 density relay calibration three-way valve is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the handle knob on the three-way valve, to achieve the three-way valve and the equipment body gas path, off. Thus, the equipment body is charged, replenishment air and SF6 density controller online calibration, testing and replacement work is realized.

Ii. Main indicators

1. Pressure level: PN68;

2. Sealing performance: absolute air leakage rate ≤1×10-9 PA.3 /s;

3. Impact performance: 600m/s

4. Impact time: 11ms

5. Operation life: 100,000 times

6. Ambient temperature: -40 ~ +75℃.

3. Instructions for use

WINFOSS-A21-3I series SF6 density relay check three-way valve is a combination valve with multiple functions, installed in the switch body, through the operation of the handle on the valve body to achieve the gas path with the body, can achieve the following functions of the operation.

1. When the equipment is in normal operation, ensure that the status arrow set ON the handle on the valve body indicates the position of "ON". At this time, the density relay is connected with the equipment gas path to monitor the pressure change in the gas room in real time;

2. The status arrow set ON the handle indicates the position of "ON". The device can be used for air replenishments, water and purity testing, and can be directly connected to the self-sealing valve joint reserved for the valve.

3. Verify the density relay directly without disassembling it. Rotate the handle so that the set status arrow indicates the "OFF" position, at which time the body gas path is cut off, and connect the tester connector with the check port on the three-way valve to perform the check operation. After the operation is complete, rotate the handle to "ON" and tighten the metal protective cap of the air supplement/check port.

Iv. Ordering Instructions:

Please provide the following content when ordering, so that we can choose the right product for you:

1. The form and size of the switch body interface;

2. When it is not available, our company can send technical engineers to carry out on-site mapping and determination;

3. The number, form and size of the self-sealing valve on the three-way valve, and the interface form and size of the SF 6 density controller;

4. Body material: aluminum alloy, stainless steel, brass;

5. Space size of combination valve installation;

V. Precautions:

1. Ensure that the valve is in the "ON" position when the equipment is running;

2. After density relay calibration, switch air replenishment and air removal, tighten the metal protective cap.
