Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a circular orifice plate which is convenient to install. Background Art

[0002] The opening of the circular segment orifice plate of the flowmeter is a part of a circle (circular segment), and the diameter of this circle is 98% of the diameter of the pipeline. The center of the arc part of the opening should be accurately positioned to make it concentric with the pipeline, so as to ensure that the opening will not be covered by the pipeline and the gaskets at both ends or due to the eccentricity of the pipeline. The circular segment orifice plate is first installed in a closed pipeline, and then the flow meter installed above the orifice plate is used to detect the flow of gas or other fluids passing through the pipeline. Most of the circular segment orifice flowmeters are used for measuring coal gas and high-viscosity gas media. In the process of installing the existing orifice plate with the pipeline, most of them are installed at the joint of the two pipelines, and then the bottom of the orifice plate is fixed on the orifice plate mounting seat to stabilize the orifice plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a circular orifice plate which is convenient to install. When the circular orifice plate is needed, the two ends of the circular orifice plate are respectively connected to the pipes on both sides, so that the circular orifice plate and the pipes on both sides are connected to each other, and the mounting base used in conjunction with the circular orifice plate is placed and fixed under the circular orifice plate, and the plug-in rod on one side of the circular orifice plate corresponds to the position of the plug-in hole groove on the top surface of the mounting base. In order to stabilize the installation connection between the circular orifice plate and the pipe, it is necessary to firmly connect the circular orifice plate and the mounting base. The operator pulls the connecting disks in the two sets of fixing components upward, and the connecting disks drive the push-pull rod and the plug-in rod to move upward, and the plug-in rod contracts into the inner cavity of the cavity column. At this time, the spring is compressed, and the circular orifice plate is placed between the two sets of arc-shaped clamping plates, and the plug-in rod is directly above the plug-in hole groove. The operator loosens the connecting disk, and the spring generates a restoring force after deformation. The plug-in rod will be driven to move toward the side close to the plug-in hole groove, and the plug-in rod will extend from the inner cavity of the cavity column until the two groups of plug-in rods are respectively plugged into the two groups of plug-in hole grooves, the plug-in rod and the plug-in hole groove are engaged and fixed, and the circular hole plate is firmly mounted on the upper end of the mounting base, and then the circular hole plate can be stably installed at the pipe docking place; if the circular hole plate needs to be separated from the pipe, that is, the circular hole plate and the mounting base are first disassembled, and the operator pulls up the two groups of connecting plates, and the connecting plates drive the push-pull rod and the plug-in rod to move upward until the plug-in rod is completely pulled out of the inner cavity of the plug-in hole groove, and the two sides of the circular hole plate lose the fixation of the two groups of plug-in rods. The operator pulls up the circular hole plate to separate the circular hole plate from the mounting base and the docking pipe. This setting facilitates users to install and disassemble the circular hole plate and the docking pipe through the fixing component, and the operation is simple and quick, which improves the use efficiency of the device.

[0016] 2. The utility model discloses a circular segment orifice plate that is easy to install. When the circular segment orifice plate has been installed and fixed to the pipeline, the flow meter body matched with the circular segment orifice plate needs to be installed and fixed on the upper end of the circular segment orifice plate, and the flow meter docking pipe at the bottom of the flow meter body is inserted into the inner cavity of the through groove. The flow meter docking pipe and the orifice plate docking pipe port are connected with each other. In order to stabilize the docking installation of the flow meter docking pipe and the orifice plate docking pipe port, the operator can rotate the knob in the forward direction, and the rotation of the knob drives the forward and reverse screw rods to rotate. Since the slide plate is limited to slide in the inner cavity of the long groove, the rotation of the forward and reverse screw rods will drive the two groups of slide plates to move closer to each other, and the slide plate drives the connecting rod component and the stable clamping plate to move at the same time until the two groups of stable clamping plates are tightly clamped on both sides of the flow meter docking pipe. This operation is conducive to the stable docking installation of the flow meter butt pipe; if the flow meter body needs maintenance and repair later, the flow meter body needs to be disassembled from the circular segment orifice plate, and the knob is turned in the opposite direction, and the positive and negative screws rotate in the opposite direction. The positive and negative screws will drive the two sets of slides and the stable clamping plates to move away from each other until the two sets of stable clamping plates are completely separated from the flow meter butt pipe. The operator pulls the flow meter body upward and pulls the flow meter butt pipe out of the inner cavity of the through groove to remove the flow meter body. This setting facilitates the operator to stably dock and install the flow meter body and the circular segment orifice plate by setting and installing the docking assembly, and also facilitates the subsequent disassembly of the flow meter body and the circular segment orifice plate. The operation is simple and quick, which improves the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
