Abstract

The utility model relates to a sectional type segmental orifice plate, and is composed of five segmental blocks provided with different slot openings. The upper end surface of a fixed block adopts a concave-shaped curved surface, an auxiliary moving block is arranged outside of the fixed block, a main moving block is arranged at the periphery of the auxiliary moving block, a trough room is arranged in the main moving block, a left moving block and a right moving block are arranged in the trough room, the labyrinths of the two lateral surfaces of the main moving block and the labyrinth of the end surface of the auxiliary moving block are identical to the labyrinth of the fixed block, forming a complete curved surface, and the curved surface and the main moving block form an opening hole space. The sectional type segmental orifice plate of the utility model adopts a sectional type block as an opening element, the area of the opening hole changes regularly depending on the replacement of the moving block, the utility model has the advantages that the structure is simple and compact, the volume is small and the operation is simple and convenient, and the utility model is in particular suitable for the flow measurement of dirty fluid.

Description

The sectional mo(u)ld segmental orifice plate
Technical field
The utility model relates to a kind of flow measurement device that is used for circular pipe, particularly relates to a kind of sectional mo(u)ld segmental orifice plate.
Background technology
Usually used valve formula standard orifice plate restriction device need be changed the orifice plate in different apertures according to the different flow scope, complex operation, and anti-dirty, stain resistance is poor; Segmental orifice plate, strong anti-dirty stain resistance because of its arc perforate, be widely used in the flow measurement of dirty fluid by the flow measurement industry, but, existing segmental orifice plate, similar to standard orifice plate, promptly in order to guarantee higher measuring accuracy, only possess single bore size, the measurement range that is contained is less.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and it is the scalable perforated area that a kind of orifice plate of need not changing is provided, simple to operate, continue to flow, volume is little, and is adapted to the sectional mo(u)ld segmental orifice plate of dirty measurement of fluid flow.
The technical solution of the utility model is:
A kind of sectional mo(u)ld segmental orifice plate, be put together by five scarce shape pieces of circle that have different slotted eyes, the fixed block upper surface is a concave curvatures, its outside is provided with an auxiliary movable block, and main movable block is located at the periphery of auxiliary movable block, has the groove chamber in it, indoor the move to left piece and the piece that moves to right of being provided with of groove, the end face labyrinth of main movable block both sides and auxiliary movable block is consistent with the labyrinth of fixed block, and constitutes a complete curved surface, and this curved surface and main movable block form the perforate space.
Sectional mo(u)ld segmental orifice plate of the present utility model, according to the symmetric characteristics of single shaft of the scarce hole perforate of circle, adopt the amalgamation piece as open element, rely on the displacement of movable block that perforated area is changed by rule, simple in structure, compact, the taking-up that has overcome element in the prior art with pack into, volume is small and exquisite, easy and simple to handle, its circle lacks the orifice plate of formula, be difficult for the long-pending booty of hiding, stop up measuring channel, be particularly suitable for flow measurement dirty, dirty fluid.
Description of drawings
Structural representation when Fig. 1 is the utility model sectional mo(u)ld segmental orifice plate perforated area maximum;
Fig. 1 is the structural representation of the utility model sectional mo(u)ld segmental orifice plate perforated area when placed in the middle;
Fig. 3 is the utility model sectional mo(u)ld segmental orifice plate perforated area structural representation hour.
Embodiment
Sectional mo(u)ld segmental orifice plate of the present utility model, be put together by five scarce shape pieces of circle that have different slotted eyes, fixed block 3 upper surfaces are curved surface, its outside is provided with an auxiliary movable block 4, and main movable block 1 is located at the periphery of auxiliary movable block 4, has groove chamber 6 in it, indoor the move to left piece 5 and the piece 2 that moves to right of being provided with of groove, the end face labyrinth of the both sides of main movable block 1 and auxiliary movable block 4 is consistent with the labyrinth of fixed block 3, and constitutes a complete curved surface, and this curved surface and main movable block 1 form the perforate space.
Figure 1 shows that the location diagram when sectional mo(u)ld segmental orifice plate perforated area is maximum, at this moment, main movable block 1, auxiliary movable block 4, fixed block 3, the circle that the inside of the piece 5 and the piece that moves to right forms maximum perforated area that moves to left lacks formula perforate space, when needs conversion perforated area, promote main movable block 1 downward translation, drive the move to left piece 5 and the piece 2 downward translations that move to right, the piece 5 that moves to left simultaneously takes place internally to move mutually in groove chamber 6 with the piece 2 that moves to right, when main movable block 1 perforate straight line portion contacts with the summit of auxiliary movable block 4, move to left simultaneously and move in the piece 5 and the piece 2 that moves to right when contacting with two side planes of auxiliary movable block 4, reach certain perforated area, as shown in Figure 2; When need continue to dwindle perforated area, promote auxiliary movable block 4 downward translations, main movable block 1 is translation downwards once more, piece 5 and move to right that piece 2 keeps down and to intrinsic displacement moves to left this moment, when main movable block 1 perforate straight line portion contacts with the summit of fixed block 3, move in move to left the simultaneously piece 5 and the piece 2 that moves to right when contacting with two side planes of fixed block 3, perforated area is minimum, as shown in Figure 3, so finish the conversion of perforated area.
