Abstract

The invention discloses an adjustable flange, which comprises a flange body (1), an adjusting slide block (2) and an adjusting bolt (4). An inner hole (5) is arranged in the flange body (1); and the bottom of the inner hole (5) is sealed by a sealing device (7); the adjusting slide block (2) is arranged in the inner hole (5) and is connected with the adjusting bolt (4), and the size of the adjusting slide block (2) is matched with the inner hole (5). The adjustable flange of the invention not only has the advantages of convenient use and simple manufacture, but also requires less equipment in tests, and the size of the inner hole of the flange body can be adjusted to adjust and change the flow and pressure of the medium in the pipeline system.

Description

technical field [0001] The invention relates to an adjustable flange. Background technique [0002] It is often necessary to set up some fixed devices to adjust the flow and pressure of the medium in the ship piping system, and generally adopt a fixed non-adjustable throttle orifice. Usually, because the resistance of the ship's pipeline cannot be accurately calculated, the designer of the pipeline system obtains the estimated inner hole size of the throttle orifice through preliminary calculations, and then obtains it through multiple tests during the actual ship trial. exact size. The traditional throttling orifice generally adopts brass plate as material, and the production department of the shipyard prefabricates multiple throttling orifice plates with different inner diameters according to the inner hole size of the throttling orifice estimated by the designer. During the sea trial, the construction personnel continued to conduct multiple tests, and finally obtained a...
