Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with an alarm mechanism. Background Art

[0002] In industrial production and daily life, valves are important devices used to control the flow of liquids or gases. They are usually used in pipeline systems to control the pressure, velocity and flow rate of fluids. When connecting pipelines, valves are connected through flanges and bolts. However, due to the complexity of the pipeline system and long-term use, the sealing performance of the connection between the valve and the pipeline may be problematic, resulting in water leakage, which not only wastes resources, but also may cause environmental pollution and safety hazards.

[0003] When the valves in the prior art are in use, fluid leakage may occur due to long-term use or loose sealing between the flanges. Leakage detection at the flange connection is time-consuming and labor-intensive, and real-time monitoring is difficult to achieve. Although some devices use pressure sensors to detect leaks, this method requires a certain pressure to be applied in the pipeline, which increases the complexity and cost of use. In addition, some devices use sound sensors to detect leaks, but this method is easily affected by environmental noise and has low reliability. Therefore, a valve with an alarm mechanism is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the defect of inconvenient detection and alarm in the prior art, and proposes a valve with an alarm mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A valve with an alarm mechanism comprises a valve body and a pipeline, flanges are installed on both ends of the valve body and one end of the pipeline, a first guide sleeve and a second guide sleeve are respectively sleeved on the two flanges, a limit ring is installed on one side of the first guide sleeve, second sealing rings are installed at the connections between the first guide sleeve, the second guide sleeve and the two flanges, gaskets are installed on both sides of the first guide sleeve and the second guide sleeve, a connecting pipe is vertically connected to the bottom of the first guide sleeve and the second guide sleeve, a limit block is fixedly sleeved on the top of the connecting pipe, and a water flow sensor is arranged at the bottom of the connecting pipe.

[0007] Preferably, a control box is installed on one side of the valve body, and an alarm and a control panel are installed in the control box.

[0008] Preferably, the water flow sensor is electrically connected to the alarm and the control panel, and a first sealing ring is installed at the connection between the flange and the valve body.

[0009] Preferably, bolts are threadedly connected between the two flanges, and the bolts are connected on both sides of the two gaskets.

[0010] Preferably, a limiting groove is provided on one side of the second guide sleeve, and a limiting ring is connected in the limiting groove.

[0011] Preferably, both the first flow guide sleeve and the second flow guide sleeve are provided with flow guide grooves inside, and the connecting pipe is vertically connected to the bottom of the flow guide groove.

[0012] The utility model has the following beneficial effects:

[0013] 1. Under the cooperation of the connecting pipe and the water flow sensor, the first guide sleeve and the second guide sleeve are respectively mounted on the two flanges. During use, if leakage occurs at the flange connection, the water will flow out of the connecting pipe through the guide groove to the bottom. At this time, the water flow sensor can detect the water flow and transmit the signal to the control panel for processing, and start the alarm, so as to detect the leakage at the valve connection and alarm, and monitor whether there is leakage at the flange connection in real time, avoiding the time-consuming and laborious manual inspection and the defects of difficult real-time monitoring. It has high reliability, is not easily disturbed by environmental noise, and can work stably for a long time;

[0014] 2. Under the cooperation of the limit ring and the first guide sleeve, when installing the first guide sleeve and the second guide sleeve, the connecting pipe is installed to the bottom position of the first guide sleeve and the second guide sleeve and limited by the limit block. The bolts completely seal the connection between the first guide sleeve and the second guide sleeve by squeezing the gasket, and cooperate with the second sealing ring to seal the connection between the first guide sleeve, the second guide sleeve and the two flanges, thereby completing the installation of the first guide sleeve and the second guide sleeve. The operation is simple and convenient to use, and the installation of the guide sleeve is relatively convenient, which facilitates the maintenance and replacement of the device and increases the practicality of the device.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A valve with an alarm mechanism comprises a valve body 1 and a pipeline 13. A control box 2 is installed on one side of the valve body 1. An alarm 201 and a control panel 202 are installed in the control box 2. A water flow sensor 12 is electrically connected to the alarm 201 and the control panel 202. When the water flow sensor 12 detects that water flows through, it transmits a signal to the control panel 202, and controls the alarm 201 to work through the control panel 202. A first sealing ring 301 is installed at the connection between the flange 3 and the valve body 1. Flanges 3 are installed on both ends of the valve body 1 and one end of the pipeline 13. Bolts 4 are threadedly connected between the two flanges 3. The bolts 4 are connected to both sides of two gaskets 9. The two flanges 3 are respectively sleeved with a first guide sleeve 5 and a second guide sleeve. 7. A limiting groove 701 is provided on one side of the second guide sleeve 7, and a limiting ring 6 is connected in the limiting groove 701. A guide groove is provided inside the first guide sleeve 5 and the second guide sleeve 7. When liquid leaks at the connection of the flange 3, the liquid will flow to the bottom through the guide groove and enter the connecting pipe 10. The connecting pipe 10 is vertically connected to the bottom of the guide groove. A limiting ring 6 is installed on one side of the first guide sleeve 5. A second sealing ring 8 is installed at the connection between the first guide sleeve 5 and the second guide sleeve 7 and the two flanges 3. Gaskets 9 are installed on both sides of the first guide sleeve 5 and the second guide sleeve 7. A connecting pipe 10 is vertically connected to the bottom of the first guide sleeve 5 and the second guide sleeve 7. A limiting block 11 is fixedly sleeved on the top of the connecting pipe 10, and a water flow sensor 12 is arranged at the bottom of the connecting pipe 10.

[0022] The use method and advantages of the utility model: When the valve with an alarm mechanism is used, the working process is as follows:

At this time, after the pipeline 13 is connected to the valve body 1 through the flange 3, the first guide sleeve 5 is connected to the second guide sleeve 7 through the limit ring 6, and the connecting pipe 10 is installed to the bottom position of the first guide sleeve 5 and the second guide sleeve 7 through the limit block 11, and a plurality of bolts 4 are installed on the two flanges 3. At this time, the bolts 4 squeeze the gasket 9 to make the connection between the first guide sleeve 5 and the second guide sleeve 7 completely tight. The first guide sleeve 5 and the second guide sleeve 7 are sealed in cooperation with the second sealing ring 8 to seal the connection between the first guide sleeve 5 and the second guide sleeve 7 and the two flanges 3, thereby completing the installation of the first guide sleeve 5 and the second guide sleeve 7. During use, if leakage occurs at the connection of the flange 3, the liquid will be diverted to the bottom through the guide groove and flow out from the connecting pipe 10. At this time, the water flow sensor 12 can detect the water flow and transmit the signal to the control panel 202 for processing, and activate the alarm 201 to alarm, thereby detecting leakage at the valve connection and giving an alarm, and monitoring whether there is leakage at the flange connection in real time, thereby avoiding the time-consuming and labor-intensive manual inspection and the defects of difficulty in real-time monitoring.
