Bib-Valve

Definition: A bib-valve is a type of draw-off tap used in domestic water-supply systems. It is closed by screwing down a rubber-washered disk onto a seating within the valve body, effectively controlling the flow of water.

Detailed Description:

  1. Construction:
  • Valve Body: The main component of the bib-valve, housing the internal mechanism and the seating for the disk.
  • Rubber Washered Disk: The valve includes a disk with a rubber washer or seal that is used to block or allow water flow. The disk is screwed down onto a seating within the valve body to close the valve.
  • Spout: The bib-valve typically has a spout or outlet from which water is drawn.
  1. Operation:
  • Opening and Closing: To operate the bib-valve, the handle or knob is turned to raise or lower the rubber-washered disk. Turning the handle raises the disk off the seating, allowing water to flow through the valve. Turning it further closes the valve by pressing the disk onto the seating, stopping the flow of water.
  • Seal: The rubber washer provides a watertight seal when the disk is pressed onto the seating, preventing leaks and ensuring a secure closure.
  1. Applications:
  • Domestic Water Supply: Bib-valves are commonly used in residential water systems for sinks, washbasins, and outdoor taps. They are ideal for controlling the flow of water in various household applications.
  • Garden Taps: They are also used for outdoor garden taps where precise control of water flow is needed.
  1. Advantages:
  • Simple Mechanism: The bib-valve’s straightforward design makes it easy to operate and maintain. The rubber washer provides a reliable seal, reducing the likelihood of leaks.
  • Durability: The construction is typically robust, suitable for frequent use in domestic water systems.
  1. Installation and Maintenance:
  • Installation: Bib-valves are installed onto water supply pipes and are usually secured with fittings. Proper installation ensures that the valve operates correctly and prevents leaks.
  • Maintenance: Regular maintenance involves checking the condition of the rubber washer and disk, tightening any loose fittings, and cleaning the spout to prevent blockages. Replacing worn or damaged washers is necessary to maintain a good seal.

In summary, a bib-valve is a type of domestic water-supply tap that controls water flow by screwing a rubber-washered disk onto a seating within the valve body. It is widely used in household plumbing for its simplicity, durability, and effective water control.
