HOLDING VALVE [9 records]

Record 1 2017-06-20

English

Subject field(s)
  • Gas and Oil Heating
  • Burners and Steamfitting
CONT

To light the pilot, [one must] hold down the button on the gas valve to start the flow of gas to the pilot burner. By holding the button down, [one is] allowing gas into the valve and, at the same time, blocking the flow of gas to the main burner outlet port while allowing it to flow to the pilot burner through a pilot tube coming from the gas valve body.

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Taps and Plumbing Accessories
CONT

Compression stop valves are most commonly used to install a shut off valve on copper tubing. This type of shut off valve compresses a brass feral onto the copper with a nut holding it tight into the shut off valve.

Record 5 2000-06-02

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
DEF

The maximum allowable pressure drop to which a valve may be subjected while fully closed. It is a function of the power available from the valve actuator for holding the valve closed, and is independent of the actual valve body rating.

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
OBS

En régulation, pour que l'étanchéité à la fermeture de la vanne soit assurée, il faut que le servomoteur puisse appliquer l'obturateur de la vanne sur son siège avec une force au moins égale à celle qui est due à la différence des pressions du fluide de part et d'autre de l'obturateur.

Record 7 1986-06-17

English

Subject field(s)
  • Rabbit Farming
CONT

Even the smallest rabbittry benefits from an automatic or semi-automatic system. The simplest watering system is semi-automatic. You fill a holding tank(perhaps just a large bucket) elevated above the hutches, and the water flows down through pipes alongside the cages. Valves are inserted into the pipe at each cage. The rabbits bite on the valves to release the water. There are two types of valves. The "dewdrop" valve has a metal stem in it which is dislodged when bit or licked. This allows the water to trickle through. After a rabbit has stopped drinking, the stem drops back into the valve opening and is held in place by the water pressure.
