Description

Technical Field

[0001] The present application relates to the technical field of water flow detection, and in particular to an insertion type flow detection device. Background Art

[0002] Impeller flowmeter, also known as turbine flowmeter or turbine flow sensor, is an instrument used to measure fluid flow. Impeller flowmeter is based on the principle of fluid dynamics and determines the flow rate of fluid by measuring the effect of the fluid flow on the rotation speed of the impeller. The core component of the impeller flowmeter is a freely rotating impeller, which is usually installed in a pipe. When the fluid passes through the pipe, it exerts a torque on the impeller, causing the impeller to rotate. The rotation speed of the impeller is proportional to the flow rate of the fluid, so by measuring the rotation speed of the impeller, the flow rate of the fluid can be indirectly measured.

[0003] In the related art, the impeller flowmeter on the market generally includes a connecting pipe section and a flowmeter, and the length of the connecting pipe section is fixed, and connecting flanges are provided at both ends of the connecting pipe section. During installation, a section of the pipe must first be cut from the installation pipe, and the length of the cut pipe must be consistent with the length of the connecting pipe section, and then the connecting pipe section must be connected to the installation pipe. The above-mentioned impeller flowmeter has a complicated installation process, is difficult to install, and cannot be adapted to flow measurement of pipes of various diameters, and has limitations.

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0023] Impeller flowmeter, also known as turbine flowmeter or turbine flow sensor, is an instrument used to measure fluid flow. Impeller flowmeter is based on the principle of fluid dynamics and determines the flow rate of fluid by measuring the effect of the fluid flow on the rotation speed of the impeller. The core component of the impeller flowmeter is a freely rotating impeller, which is usually installed in a pipe. When the fluid passes through the pipe, it exerts a torque on the impeller, causing the impeller to rotate. The rotation speed of the impeller is proportional to the flow rate of the fluid, so by measuring the rotation speed of the impeller, the flow rate of the fluid can be indirectly measured.

[0024] In the related art, the impeller flowmeters on the market generally include a connecting pipe section and a flowmeter, and the length of the connecting pipe section is fixed, and connecting flanges are provided at both ends of the connecting pipe section. During installation, a section of the pipe must first be cut from the installation pipe, and the length of the cut pipe must be consistent with the length of the connecting pipe section, and then the connecting pipe section must be connected to the installation pipe. The installation process of the above-mentioned impeller flowmeter is complicated and difficult to install. The device uses an installation mechanism, a connecting nut and a flowmeter to facilitate the insertion of the flowmeter on the connecting nut and the installation mechanism, so that the impeller of the flowmeter can enter the pipeline for detection. The entire device has a simple structure, is easy to install and maintain, and can adapt to the use of pipelines of different diameters.

[0025] The insertion flow detection device can be used in pipelines with different diameters, and during installation, there is no need to intercept or cut the pipeline to be detected, so it is convenient and quick to use.

[0026] like Figure 1As shown, an embodiment provides an insertion type flow detection device, including: a mounting mechanism 100, a connecting nut 200 and a flow meter 300. The mounting mechanism 100 includes a connecting cylinder 110 and a ball valve 120, wherein the connecting cylinder 110 is arranged on the pipeline, and the ball valve 120 is connected to the connecting cylinder 110; the connecting nut 200 is arranged at one end of the ball valve 120 away from the connecting cylinder 110; the flow meter 300 includes an impeller, a rod body 320 and a meter body 330 connected in sequence, wherein the impeller is located in the pipeline, and at least a part of the rod body 320 is sequentially penetrated in the connecting nut 200, the ball valve 120 and the connecting cylinder 110.

[0027] It is understandable that the connecting tube 110 can be welded to the pipeline or installed on the pipeline through a flange. The connecting tube 110 is generally cylindrical, and the outer peripheral surface of the upper end thereof is provided with a thread for connecting with the ball valve 120 .

[0028] It is understandable that the ball valve 120 is a common valve control mechanism, which is not specifically limited herein. The ball valve 120 is connected to the connecting tube 110 and is used to close the connecting tube 110 during installation to prevent water in the pipeline from flowing out of the connecting tube 110.

[0029] For example, during installation, the connecting tube 110 is first welded to the pipeline, and then the ball valve 120 is connected to the connecting tube 110. The ball valve 120 is opened, and a hole-opening tool is inserted from the ball valve 120 and passed through the connecting tube 110 to open a hole in the pipeline. After the hole is opened, the ball valve 120 is removed and gradually closed until the hole-opening tool is completely removed from the ball valve 120. Through the above-mentioned installation mechanism 100, the flow meter 300 can be installed without destroying the original structure of the pipeline, and the installation is convenient.

[0030] It is understandable that a water level sensor is provided at one end of the rod body 320 close to the impeller to sense the water level in the pipeline. When the flow meter 300 is installed on the pipeline, if water is detected in the pipeline, the water level sensor outputs a signal to the meter body 330, and the meter body 330 starts measuring after receiving the signal. If no water is detected in the pipeline, the water level sensor outputs a signal to the meter body 330, and the meter body 330 gives an alarm.

[0031] For example, when installing the flow meter 300, gradually open the ball valve 120, and insert one end of the impeller of the flow meter 300 into the connecting nut 200, the ball valve 120 and the connecting tube 110 in sequence until the impeller enters the pipeline. The insertion flow detection device adopts a plug-in method, which can be adapted to flow measurement of pipelines of various diameters, has high adaptability, and is easy to plug in.

[0032] like Figure 1As shown, the device may further include a waterproof mechanism 400, which is disposed at one end of the connection nut 200 away from the ball valve 120 and is sleeved on the rod body 320. The waterproof mechanism 400 can prevent water from overflowing from the ball valve 120.

[0033] It is understandable that the waterproof mechanism 400 may include: a water-stopping gasket 410 and a water-stopping nut 420, the water-stopping gasket 410 is disposed in the connecting nut 200, the water-stopping nut 420 is connected to the connecting nut 200, and the water-stopping nut 420 is sleeved on the rod body 320. The water-stopping gasket 410 and the water-stopping nut 420 can prevent water from overflowing from the ball valve 120.

[0034] like Figure 1 As shown, in some embodiments, the connecting nut 200 includes: a lower connecting part 210 and an upper connecting part 220 connected to each other, the lower connecting part 210 is connected to the ball valve 120, the water stop gasket 410 is arranged in the upper connecting part 220, and the water stop nut 420 is connected to the upper connecting part 220 and abuts against the water stop gasket 410.

[0035] like Figure 1 As shown, in some embodiments, one end of the ball valve 120 is threadedly connected to the connecting cylinder 110, and the other end of the ball valve 120 is threadedly connected to the connecting nut 200. The ball valve 120 is threadedly connected to the connecting cylinder 110 and the ball valve 120 respectively, thereby improving the connection stability between the ball valve 120 and the connecting cylinder 110 and the ball valve 120.

[0036] like Figure 1 As shown, in some embodiments, the mounting mechanism 100, the connecting nut 200 and the flow meter 300 are coaxially connected. In this way, it is convenient for the flow meter 300 to be directly inserted into the connecting nut 200 and the mounting mechanism 100, which is convenient for installation.
