Tuotteen yleiskatsaus

TheTeollisuuden signaalin manuaalinen uritettu läppäventtiili on palontorjuntajärjestelmiin suunniteltu erikoissäätöventtiili, automaattiset sprinklerijärjestelmät, ja palopostiverkot. Valmistettu erittäin lujasta pallografiittivaluraudasta (QT450-10) täysin EPDM-kapseloidulla levyllä, Tämä venttiili tarjoaa kuplatiivisen sulkemisen ja kaksisuuntaisen tiivistyksen ilman vuotoa. Integroitu signaalin takaisinkytkentälaite muuntaa venttiilin auki/kiinni -tilan sähköisiksi signaaleiksi (DC24V/3A), mahdollistaa reaaliaikaisen valvonnan palonhallintakeskuksesta venttiilin tahattoman sulkeutumisen estämiseksi, mikä voi vaarantaa järjestelmän turvallisuuden. Saatavana koot DN50 - DN1200 (2″ - 48″) uritetuilla päätyliitännöillä, jotka ovat AWWA-C606-standardien mukaisia, tämä venttiili tarjoaa nopeasti, työkaluton asennus – jopa 3 kertaa nopeampi kuin laippaliitännät. Tämä venttiili on luotettava valinta palosuojaukseen, vesihuolto, kemiallinen, ruokaa, sekä teollisuuden putkistojärjestelmät, jotka edellyttävät sekä virtauksen ohjausta että valvontasignalointia.

Working Principle

The signal grooved butterfly valve operates through a simple yet reliable mechanism integrating flow control and status monitoring:

1. Normal Operating State: The valve remains fully open (90°) to ensure unobstructed water flow in the fire protection network. The worm gear self-locking mechanism maintains the valve position, preventing accidental closure due to pressure fluctuations or external impacts.
2. Flow Control Operation: To close the valve for maintenance or isolation, turn the handwheel clockwise. The worm gear drives the disc to rotate 90° to the fully closed position. Reverse rotation opens the valve.
3. Signal Feedback: The valve’s internal cam mechanism activates micro switches at specific positions: fully open (90°) triggers the “Avata” signaali, fully closed (0°) triggers the “Lähellä” signaali. If the valve is closed 25% (1/4 of full opening), the signal device triggers an alarm to the fire control center.
4. Emergency Locking: The handwheel features a locking hole that allows a padlock to secure the valve in position, preventing unauthorized operation.

FAQ

Q1: What is the difference between a supervised butterfly valve and a standard butterfly valve?

A: Supervised butterfly valves feature a built-in microswitch and signal feedback mechanism that converts the valve’s open/closed status into an electrical signal for transmission to the fire control center. Standard butterfly valves offer only manual flow control. Supervised butterfly valves are critical components in fire protection systems, meeting code requirements for valve status monitoring.

Q2: What are the advantages of grooved connections?

A: Grooved connections eliminate the need for welding, langoitus, or hot work, allowing for rapid installation using just two couplings. Installation is three times faster than flanged connections, requires fewer bolts, and takes up less space. They are particularly suitable for fire protection projects with tight schedules, space constraints, tai “no hot work” policies.

Q3: What media and temperatures are EPDM seals suitable for?

A: EPDM (Ethylene Propylene Diene Monomer) seals are suitable for water, clean water, and mild chemicals, with an operating temperature range of -20°C to +80°C. EPDM offers excellent resistance to aging, ozone, and weathering, making it the standard choice for fire protection systems and water treatment applications.

Q4: How does the signal feedback mechanism work?

A: The valve features a built-in cam linked to a microswitch. An “Avata” signal is triggered when fully open (90°), and a “Closed” signal is triggered when fully closed (0°). If the valve is inadvertently closed by 25% (one-quarter of its full travel), the signaling device transmits an alarm signal to the fire control center. The output is a DC24V/3A passive switch signal.

Q5: What is the difference between worm gear operation and lever (handle) operation?

A: Worm gear operation utilizes a gear reduction mechanism to provide mechanical advantage, resulting in lower operating torque and easier, smoother handling; it is suitable for large-diameter valves (DN100 and above). The worm gear mechanism includes a self-locking function to prevent accidental valve closure. Lever operation is simpler and more cost-effective, making it suitable for small-diameter valves (DN100 and below).
