Description
Technical Field
The utility model relates to a flow control device specifically is a multistage dislocation throttle structure of reassembling type.
Background
The valve is an important flow regulation control device, has quite various varieties and specifications, is mainly divided into a shut-off valve, a check valve, a regulating valve and the like, and is widely used in high-temperature and high-pressure fields such as power stations, metallurgy, petrifaction and the like. The orifice plate is mainly used for regulating pressure of fluid, and the resistance of the orifice plate is used for reducing the pressure of the fluid. As shown in fig. 2, the existing orifice plate 9 is welded on the inner wall of the pipe body connected with the inlet of the valve, so that the structure is complex, the manufacturing difficulty is increased, and the later maintenance and cleaning liquid are inconvenient to further improve.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, providing a multistage dislocation throttling arrangement of reassembling type, this throttling arrangement should have simple structure, installation and maintenance convenience, the effectual characteristics of step-down.
The technical scheme of the utility model is that:
multistage dislocation throttle structure of reassembling type, its characterized in that: the structure comprises two flanges, a plurality of throttle orifice plates arranged between the two flanges, a butt ring arranged between every two throttle orifice plates and a fastener which is used for connecting the two flanges and clamping and fixing the throttle orifice plates;
the flow passage holes in the two adjacent throttle orifice plates are arranged in a staggered mode, protruding rings which are suitable for the notches of the flanges are arranged on the two sides of each throttle orifice plate respectively, grooves which are suitable for the protruding rings are arranged on the butt joint rings, and the protruding rings extend into the notches of the flanges and the grooves of the butt joint rings respectively.
Sealing rings are arranged between the throttling orifice plate and the flange and between the throttling orifice plate and the butt ring; the sealing ring is sleeved on the convex ring of the orifice plate.
The outer diameter of the convex ring is smaller than that of the orifice plate.
The fastener is a bolt and a nut.
The utility model has the advantages that:
the utility model discloses install in valve import position, the bolt that utilizes two original flanges of connection (valve flange and pipeline flange) to use just can be fixed and even as an organic whole with each orifice plate pressure fastening, needn't change valve structure, and it is all very convenient to install, dismantle and wash, can play the secondary regulation step-down to the fluid (accomplish the step-down on orifice plate and valve respectively), has promoted the step-down grade greatly to production and use cost have been reduced.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1, the detachable multistage dislocation throttling structure includes two flanges 1, a plurality of orifice plates 2, a plurality of butt rings 3, a plurality of sealing rings 4 and fasteners.
This practicality is installed and is used for connecting valve and pipeline in the valve import position, and consequently two flanges are valve flange and pipeline flange respectively, and the opening position system of flange has notch 1.1, and the border position system of flange has screw 1.2. The flange is of conventional construction.
The two sides of the throttling orifice plate are respectively provided with a convex ring 2.1, the outer diameter of the convex ring is smaller than that of the throttling orifice plate, the size of the convex ring is matched with that of a flange notch, and the middle of the throttling orifice plate is provided with a plurality of flow passage holes 2.2 (the flow passage holes are arranged in the convex ring). The number of the throttling orifice plates is determined according to the pressure reduction requirement, and the throttling orifice plates are generally 2-4.
The butt joint ring is provided with a groove 3.1 which is matched with the convex ring, the inner diameter of the groove is slightly larger than the outer diameter of the convex ring, and the number of the butt joint rings is determined according to the number of the throttle orifice plates. The sealing rings are sleeved on the convex rings at two sides of the orifice plate, and the inner diameters of the sealing rings are slightly larger than the outer diameters of the convex rings. The thickness of the convex ring is respectively greater than the depth of the flange notch, the depth of the butt joint ring notch and the thickness of the sealing ring. The fastener is used for connecting two flanges and can adopt a bolt 5 and a nut 6.
The throttling orifice plate and the butt joint ring are arranged between the two flanges in parallel, the runner holes in the adjacent throttling orifice plates are arranged in a staggered mode, the sealing rings are arranged on the convex rings at two sides of the throttling orifice plate, the butt joint ring is arranged between the two adjacent throttling orifice plates, the convex rings at two sides of the throttling orifice plate respectively extend into the notches of the flanges or the grooves of the butt joint ring (play a limiting role), the bolts penetrate through the screw holes of the two flanges and then are screwed down by the nuts, therefore, the throttling orifice plate and the butt joint ring arranged between the flanges are tightly pressed, and the sealing rings can ensure that leakage does not occur between the flanges and the throttling orifice plate and between the throttling orifice plate and the.
The utility model discloses promoted the step-down grade greatly, it is applicable in the bore for DN50mm-DN250mm and pressure for PN10MPa-PN20 MPa's valve.
