Non-disassembly ball valves
1：Introduction
1)Non-disassembly ball valves apply to connect SF6 density relays to electrical switches.
2)Design compactly and maintenance-free.
3)The knob marking indicates that the airflow is closed or open, and controls the flow rate due to the ball inside the valve.
4)Subject to a tight gas-tightness test before leaving the factory.
5)The three-way valve structure can be used repeatedly, high-sealing performance of the metal seal structure.
2. Product advantages:
1), Non-disassembly valve block built-in valve, individually close the switch body gas circuit. It can be tested by the SF6 density relay non-disassembly to replace and maintain quickly.
2),The three-phase gas circuit takes an independent density relay to display the density and quickly determine the phase sequence of the leakage phase.
3), The connecting block body is made of 304 stainless steel / national standard H59 material, high strength, corrosion resistance, and low air leakage rate.
4),Switch filling port interface M27X1.5, material copper nickel-coated.
Switch handle: aluminium alloy will not cause ageing cracks. Can lock the switch state when opening or closing to prevent non-staff mistaken operation.
3:Technical requirements:
1), the main body material: 6 series aluminium / GB H59 / 304.
2),Max pressure resistance: 2MPa
3),Safe using pressure: 1.0MPa
4),Temperature range: -40℃-80℃.
5),Annual air leakage rate: not more than 10-15Mpam3/s
6),Material of sealing ring: EPDM(E)
7),Switch handle: 6 series aluminium/GB H59/304.
4,Main features:
1),To be convenient to calibrate or replace the SF6 density relay without disassembling the SF6 density relay and original gas circuit.
2),To be convenient for SF6 equipment to carry out micro-water measurement.
3),To be convenient to make up the gas for SF6 equipment.
4),No need to disassemble the connector, can operate independently. Convenient, labor-saving, time-saving.
5),It avoids the damage of sealing surfaces and seals caused by disassembly and effectively protects the gas tightness of SF6 equipment.
