Dispositif de sécurité industriel d'arrêt automatique de pipeline
Informations de base
Modèle: Series B
Description du produit
Pipeline safety automatic prevention equipment series B GF GPE 940F/H/Y-6/10/16/25C/P/R
B Series adopts bias hemisphere seal form structure, motion trajectory is angular stroke, and the opening control is similar to the traditional ball valve. When the setting is often open (often closed) locking in the emergency Safe mode, the system enters the automatic detection alert attendance State, at this time the valve board loses the movement freedom, the system magnetic field for the equipment reserves sufficient potential energy to maintain the equilibrium stable state, waits the conditional directive implements 1 seconds closes (opens) the process. is the dangerous product pipe network and city gas pipe network control preferred products. Installation azimuth recommended preferred axis level, the special special.
1, according to GB and Q/T standard requirements for manufacturing, design unique, high degree of automation, maintain stable and safe, reliable, fast and close.
2, equipment-owned electrical compliance with the safety of this type, explosion-proof design belongs to the product.
3, its structure adopts the principle of eccentric clamping mechanism to achieve the purpose of brake tight, regulating and closing through the transmission system, sealing pair is the metal surface ring with hard face contact sealing, double eccentric structure in the opening of the valve spool in the indoor, the circulation cross-section is large, and the valve is not washed, closed when the spool is not washed, open when the spool spherical surface gradually along the valve seat, effectively removing the barrier, to achieve reliable sealing. It is particularly effective for mixing flow conveying of two-phase miscible solids precipitation.
4, the valve hemisphere with bimetal, the Masterbatch on the heap welding different alloys, the valve seat also for the corresponding surfacing with special treatment, sealing surface combined into anti-corrosion, wear-resisting, high-strength and other types, to meet the needs of different occasions.
5, tight sealing, the transportation of harmful gases can reach zero leakage
6, Drive mode: Compatible with all kinds of alarm signal instructions, automatic response quickly, and control accurately in place.
7, Communication Signal Directive Category:
(1) Fire alarm signal: (Gas alarm signal, fire detection signal, temperature signal, light signal, smoke signal).
(2) Distributed fiber Bragg grating leakage, fire alarm signal.
(3) pressure signal and flow signal.
(4) Vibration signal.
(5) network computer and wireless remote control telemetry, GSM satellite communication signal.
8, equipment emergency power--------gravity.
Do not rely on mains, hydraulic, gas source, accumulator and other energy.
