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

A kind of adjustable flange
Technical field
The present invention relates to a kind of adjustable flange.
Background technique
The device of some secured adjusted rate-of flows and pressure often need be set in the ship pipeline system, generally take fixed uncontrollable restricting orifice.Generally, because the resistance of ship pipeline can't calculate accurately, the artificer of pipe-line system draws size accurately by test of many times between real ship shake down period then through the preliminary interior hole dimension that calculates the restricting orifice of estimating.It is material that traditional restricting orifice generally adopts brass sheet, and the interior hole dimension of the restricting orifice that shipyard production department estimates according to artificer's endoporus is made the restricting orifice of polylith different inner diameters in advance.Between shake down period, the workmen constantly carries out test of many times, finally obtains the internal diameter size of suitable restricting orifice.Because traditional restricting orifice is installed in the pipe-line system, duration of test need stop by the relevant device of pilot system, and the situation that exists leakage of oil to leak, and test needs lot of manpower and material resources.
Summary of the invention
The invention provides a kind of adjustable flange, it is not only easy to use, it is simple to make, and the equipment that experiment needs is few, reaches the flow of regulating the medium that changes pipe-line system and the purpose of pressure by the size of regulating the flange body endoporus.
The present invention has adopted following technological scheme: a kind of adjustable flange, and it comprises flange body, adjusting slider and regulates bolt, is provided with endoporus in the described flange body; Described endoporus bottom is by the seal arrangement sealing, and described adjusting slider is positioned at endoporus and links to each other with the adjusting bolt, and the size and the endoporus of described adjusting slider are complementary.
Described flange body outside is provided with the externally connected pipe flange, is provided with restricting orifice between described externally connected pipe flange and exterior line; Described endoporus outlet port is provided with the spacing flange, and the adjusting bolt passes the spacing flange and links to each other with adjusting slider; Link to each other by gasket seal between described externally connected pipe flange and flange body.
The present invention has following beneficial effect: the present invention is installed in restricting orifice in the pipe-line system, between shake down period, need not arrestment, the situation that leakage of oil is leaked can not occur, adjust the interior hole dimension of orifice plate by adjusting the length of regulating bolt, finally satisfy the normal operation of equipment and pipe-line system.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
As shown in Figure 1, the present invention is a kind of adjustable flange, it comprises flange body 1, adjusting slider 2 and regulates bolt 4, be provided with endoporus 5 in the described flange body 1, described flange body 1 outside is provided with externally connected pipe flange 6, be provided with restricting orifice between described externally connected pipe flange 6 and exterior line, described externally connected pipe flange 6 links to each other by gasket seal with 1 of flange body.Described endoporus 5 bottoms are by seal arrangement 7 sealings, and described adjusting slider 2 is positioned at endoporus 5 and links to each other with adjusting bolt 4, and the size of described adjusting slider 2 and endoporus 5 are complementary.Described endoporus 5 outlet ports are provided with spacing flange 3, and adjusting bolt 4 passes spacing flange 3 and links to each other with adjusting slider 2.
During installation, use bolt that externally connected pipe flange 6 and exterior line are fixed, restricting orifice is located in the exterior line or is arranged in the externally connected pipe flange 6.Length by manual adjustment is regulated bolt 4 changes the position of adjusting slider 2 in endoporus 5.When adjusting slider 2 is positioned at topmost, interior hole dimension maximum; When adjusting slider 2 is positioned at bottom, interior hole dimension minimum.The mated condition of endoporus and wildcard flange 1 endoporus by adjusting slider 2, thus reach the flow and the pressure of the medium that changes pipe-line system.

Claims (4)
