Hvad er de forskellige typer VVS -fittings?

Plumbing fittings come in all shapes and sizes, with each individual type being used for a specific purpose. Joints or elbows are commonly used, as well as tee and cross fittings. Most plumbing fittings are used to change the direction of the water's flow or to stop it altogether.

Elbow joints are plumbing fittings that are used to change the direction of the water's flow to either a 45° or 90° angle. De bruges ofte under dræn og andre inventar, hvor en dræning bruges til bedre at regulere den hastighed, hvormed vandet forlader armaturet og kommer ind i septik- eller kloaksystemet. Elbow ends may be socketed, butt welded, or threaded. En gadealbue er en variation af denne type montering, der generelt bruger mandlige til kvindelige tråde.

tee -leddet er en anden type VVS -montering, der primært bruges til at kombinere eller opdele en strøm af vand. Both ends are generally the same size, although there are varieties available that have differing inlet and outlet sizes, also known as a reducer joint. Tee joints can also be used in certain computer components.

Cross joints are also plumbing fittings. They have three inlet valves and one outlet valve or vice versa, and are commonly used for sprinkler systems. Often, they are not used when adding plumbing to a home because they are more expensive than using multiple tee joints.

Plumbing fittings are not always joints. This is the case with caps and plugs, both of which are used for closing off the end of a pipe. The difference between the two is in the way each fitting is designed. Caps fit over the ends of a pipe, generally being threaded so they screw in. Plugs fit into the end of a pipe. Both are generally gas and water tight.

Clean-outs are also plumbing fittings that are used on a temporary basis. They are installed in an easily accessible area to allow an auger or pipe snake to be inserted to clean oUT tilstoppede områder med rør. Når rørene er rengjort, fjernes rengøringerne typisk.

De fleste VVS -fittings er lavet af forskellige typer plast eller metal, oftest polyvinylchlorid (PVC). Kobber og andre metalfittings kan også være tilgængelige for ældre hjem, der kan have kobberafløb. Fittings sælges generelt i hjemmeforbedring og VVS -forsyningscentre og er installeret ved hjælp af specialiserede VVS -lim og klæbemidler.
