Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a multi-hole orifice plate flow meter. Background Art

[0002] The orifice flowmeter is a widely used differential pressure flowmeter. It measures the flow of fluids such as gas, steam, and liquid by installing a standard orifice plate in the pipeline. When the fluid flows through the orifice plate, a local contraction will form at the orifice plate, resulting in an increase in flow velocity, thereby generating a static pressure difference before and after the orifice plate. This pressure difference is proportional to the flow rate of the fluid. By measuring this differential pressure, the flow rate of the fluid can be calculated. The working principle of the orifice flowmeter is based on the fluid continuity equation and the Bernoulli equation. When the fluid flows through the orifice plate, a local contraction will form at the orifice plate, resulting in an increase in flow velocity, thereby generating a static pressure difference before and after the orifice plate. By measuring this differential pressure, the flow rate of the fluid can be calculated. The basic formula of the orifice flowmeter involves parameters such as the density of the fluid, flow velocity, throttling hole or throat diameter, and the inner diameter of the upstream pipe.

[0003] The existing orifice flowmeter calculates the flow rate of the fluid by measuring the pressure difference on both sides of the orifice. Often, the existing pressure pipe is connected to one end of the connecting pipe without a protective mechanism. When there is a slight seal, it may affect the measurement accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-hole orifice plate flow meter to achieve the purpose of solving the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a multi-hole orifice plate flowmeter, comprising a T-shaped plate,

[0006] A multi-hole orifice plate flow body fixedly mounted on the top of the T-plate;

[0007] and a processing assembly disposed at the bottom of the T-shaped plate;

[0008] The processing assembly includes a stabilizing mechanism mounted at the bottom position of the T-plate;

[0009] A connecting mechanism is installed at the bottom of the T-shaped plate, and the connecting mechanism is connected to the stabilizing mechanism.

[0010] Preferably, a display is fixedly mounted on the front of the porous orifice plate flow body, and a connecting conduit is fixedly mounted on the bottom of the T-shaped plate.

[0011] Preferably, there are two connecting conduits, the two connecting conduits are equal in shape and size, and the two connecting conduits are symmetrically arranged relative to the middle surface of the T-shaped plate in the front-to-back direction.

[0012] Preferably, the stabilizing mechanism includes side plates, which are fixedly mounted on the side walls of the T-plate, a long rod is rotatably mounted on the bottom of the side plate through a bearing, a U-shaped block 1 is fixedly mounted on the side wall of the long rod, a U-shaped block 2 is fixedly mounted on the bottom of the long rod, a slide plate is provided in contact with the inner wall of the U-shaped block 2, the inner wall of the slide plate is slidably connected to the side wall of the connecting conduit, a connecting rod is fixedly mounted on the bottom of the slide plate, and a clamping block is fixedly mounted on the bottom of the connecting rod.

[0013] Preferably, the inner wall height of the U-shaped block 2 is the same as the height of the slide plate, and the inner wall height of the U-shaped block 1 is the same as the height of the slide plate.

[0014] Preferably, there are two long rods, the two long rods are equal in shape and size, and the two long rods are symmetrically arranged relative to the middle surface of the skateboard in the front-to-back direction.

[0015] Preferably, the connecting mechanism includes a pressure-conducting tube, which is fixedly connected to the bottom of the connecting conduit, a linkage rod is fixedly installed on the side wall of the pressure-conducting tube, a nut is threadedly installed on the side wall of the linkage rod, and the top of the pressure-conducting tube is arranged in contact with the inner wall of the clamping block.

[0016] The utility model provides a multi-hole orifice plate flow meter. It has the following beneficial effects:

[0017] (1) The utility model allows the operator to lower the position of the slide plate, so that the clamping block at the bottom of the slide plate contacts the top of the linkage rod. The clamping block will clamp and protect the side walls of the connecting pipe and the linkage rod, thereby improving the sealing between the connecting pipe and the linkage rod. Then, the position of the long rod can be directly rotated, and the long rod drives the position of the U-shaped block 2 to rotate, so that the inner wall of the U-shaped block 2 contacts the side wall of the slide plate, thereby limiting the position of the slide plate. When the connecting pipe is disassembled, the slide plate can be directly moved to the upper position, and the inner wall of the U-shaped block 1 contacts the side wall of the slide plate to limit the position of the slide plate. This solves the problem of the existing orifice flowmeter that calculates the flow rate of the fluid by measuring the pressure difference on both sides of the orifice plate. Often, the existing pressure pipe is connected to one end of the connecting pipe, and no protective mechanism is provided between them. When there is a slight sealing, it may affect the measurement accuracy.

[0018] (2) When the operator needs to measure the flow rate inside the connecting pipe, the utility model sleeves the flange end of the connecting pipe on the surface of the linkage rod and then directly rotates the position of the nut. Since the inner wall of the nut is threadedly connected to the side wall of the linkage rod, the connecting pipe and the pressure pipe can be quickly connected, which is convenient for the operator to detect the flow rate inside the connecting pipe.
