Description

A vertical installation structure of a positive displacement flow meter

Technical Field

The utility model relates to the technical field of volumetric flowmeters, in particular to a vertical installation structure of a volumetric flowmeter.

Background Art

In the fields of industry and construction, it is very important to accurately measure the flow of fluids. As a common flow measurement device, the volumetric flowmeter has the characteristics of high reliability and good accuracy. It is widely used in the flow measurement of various liquids and gases. In the vertical installation structure, the main part of the volumetric flowmeter is usually a vertically placed pipe. The fluid enters from the bottom of the flowmeter and passes through a series of flow measurement devices. These devices usually include rotating blades or gears, vortex sensors, etc., which are used to measure the volume or speed of the fluid passing through, so as to calculate the flow value. The vertical installation structure is suitable for some occasions that require vertical pipes, such as water supply systems in high-rise buildings, industrial process pipelines, etc. This installation structure can save space, and through vertical installation, it is easier for the fluid to pass through the flowmeter smoothly.

When traditional volumetric flowmeters are installed on vertical pipes, in order to ensure the sealing of the connection parts and prevent leakage, appropriate pipe connectors such as flanges and threaded connections are usually used to connect the flowmeter to the pipe. However, this installation method does not provide support and limit structures for the flowmeter, which may cause the vertical position of the flowmeter to be incorrect, thereby affecting the flowmeter's accurate measurement of fluid flow.

Therefore, it is necessary to provide a vertical installation structure of a volumetric flowmeter to solve the above technical problems.

2. The utility model uses a pull rope, a hook and a hanging ring, and hangs the hook on the hanging ring, so that the two support arms are placed upward at a certain angle, as shown in Figure 2. In this state, the distance between the support arm and the vertical pipe will increase, and the support arm, the upper clamping piece and the lower clamping piece can be prevented from hindering the installation of the volumetric flow meter body. In this way, the convenience of people's installation is improved.

A vertical installation structure of a volumetric flow meter, comprising:

The volumetric flowmeter body 1 and the vertical pipe 3, both ends of the volumetric flowmeter body 1 are provided with connecting flanges 4, the upper parts of both sides of the outer wall of the volumetric flowmeter body 1 are hinged with support arms 5, one end of the support arm 5 is welded with a mounting block 6, the bottom of the mounting block 6 is provided with an upper clamping piece 7, the bottom of the upper clamping piece 7 is hinged with a lower clamping piece 8, and the front side of the outer surface of the upper clamping piece 7 is provided with an upper fixing block 15;

A lower fixing block 12 is arranged on the front side of the outer surface of the lower clamping member 8, and symmetrically distributed threaded columns 14 are fixedly installed on the top of the lower fixing block 12. Positioning grooves 16 corresponding to the positions and quantities of the threaded columns 14 are arranged on the front side of the upper fixing block 15, and butterfly nuts 13 are threadedly connected on the outer walls of the threaded columns 14.

Hanging rings 11 are welded on the outer wall of the volumetric flowmeter body 1 above the two support arms 5 , a pull rope 9 is fixedly connected to the upper side of the outer wall of the support arm 5 , and a hook 10 is fixedly connected to one end of the pull rope 9 .

In one of the embodiments, the bottom of the mounting block 6 is arc-shaped, and the curvature of the bottom of the mounting block 6 is adapted to the curvature of the outer surface of the upper clamping member 7. The mounting block 6 is fixedly connected to the upper clamping member 7 by bolts, thereby realizing the detachability of the clamping member 7 and the lower clamping member 8. When it is damaged, it is easy to replace it, which is convenient for people to use.

In one of the preferred embodiments, the inner surfaces of the upper clamping member 7 and the lower clamping member 8 are bonded with anti-slip pads 2, which improves the friction force between the upper clamping member 7, the lower clamping member 8 and the outer wall of the vertical pipe 3, making the fixation between the upper clamping member 7, the lower clamping member 8 and the vertical pipe 3 more secure.

In one embodiment, the upper clamping member 7, the upper fixing block 15 and the positioning groove 16 are an integrally formed structure, and the lower clamping member 8 and the lower fixing block 12 are an integrally formed structure, which improves the structural strength of the upper clamping member 7 and the lower clamping member 8.

In one preferred embodiment, the material of the pull rope 9 is nylon rope. Nylon rope has the characteristics of high strength, wear resistance and corrosion resistance, making the pull rope 9 more durable.

The working principle of the present utility model is as follows: the specific structure of the volumetric flow meter body 1 can refer to the prior art, which can be easily implemented by those skilled in the art. The contents not described in detail in this specification belong to the prior art known to those skilled in the art. The volumetric flow meter body 1 is connected to the vertical pipe 3 through the connecting flange 4, and then the two support arms 5 are rotated. The rotation of the support arms 5 will change the position of the upper clamping member 7 and the lower clamping member 8 through the mounting block 6, and the upper clamping member 7 and the lower clamping member 8 in the open and closed state are directly clamped on the outer wall of the vertical pipe 3 at both ends of the volumetric flow meter body 1. After the clamping member 7 is fully engaged with the lower clamping member 8, the threaded column 14 at the top of the lower fixing block 12 will extend through the interior of the positioning groove 16 to the top of the upper fixing block 15. At the same time, the butterfly nut 13 is threadedly connected to the outer wall of the threaded column 14, so that the butterfly nut 13 is tightened on the top of the upper fixing block 15, so that the upper clamping member 7 and the lower clamping member 8 are firmly clamped on the outer wall of the vertical pipe 3, so that the support arm 5, the upper clamping member 7 and the lower clamping member 8 form a vertical limit support installation structure, which prevents the flow meter from being deflected or tilted during the vertical installation process, resulting in inaccurate measurement of the fluid flow. At the same time, in the case of long-term operation or pipeline vibration, the vertical limit support installation structure can prevent the volumetric flow meter body 1 from loosening or shifting, resulting in loosening or leakage of the connection part, thereby ensuring the stability and accuracy of the entire flow meter system.

When installing the volumetric flow meter body 1, first hang the hook 10 on the hanging ring 11, so that the two support arms 5 are placed upward at a certain angle, as shown in FIG2. In this state, the distance between the support arm 5 and the vertical pipe 3 is increased, and the support arm 5, the upper clamping member 7 and the lower clamping member 8 can be prevented from hindering the installation of the volumetric flow meter body 1. In this way, the convenience of people's installation is improved.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
