Abstract
A manifold (1) comprises a body (2) with a plurality of branch fittings (3) diverging therefrom. The inner surface of the body (2) is conical such that the inner cross-sectional area of the body (2) decreases in the direction of flow. The manifold (1) is particularly well suited for use in tap water systems. The manifold (1) can be manufactured e.g. from polyphenyl sulfone PPSU, polysulphone PSU, polyvinylidene fluoride PVDF, glass fiber reinforced polyamide PA, or cross-linked polyolefin plastic.
Claims14
A manifold comprising a body with a plurality of branch fittings diverging therefrom, wherein the inner surface of the body is conical such that the inner cross-sectional area of the body decreases in the direction of flow, and
- the manifold comprises ribs around the body, the ribs having outer diameters equal in size irrespective of the inner diameter of the body.
A manifold comprising a body with a plurality of branch fittings diverging therefrom, wherein
- the inner surface of the body is conical such that the inner cross-sectional area of the body decreases in the direction of flow,
- the outer surface of the body is also conical, and
- the coning angle of the outer surface of the body of the manifold is larger than the coning angle of the inner surface of the body of the manifold, whereby the wall of the body is thinner at the rear part of the manifold than at the front part thereof.
