Abstract
Description
Technical Field
[0001] The utility model relates to a valve system, in particular to an air valve with a pipeline leakage monitoring function. Background Art
[0002] For the transportation of liquids, pipelines are usually used. To ensure the discharge of air in the pipeline, air valves are usually installed on the pipeline. To understand the physical parameters of the liquid in the pipeline at all times, pipeline leakage detection is usually carried out. For traditional pipeline leakage detection, an installation hole needs to be drilled on the pipeline, and a pressure sensor is installed on the installation hole. This method has problems such as large workload and complex construction. In addition, foreign matters are likely to accumulate and block at the sensor installation position, which will have a greater impact on the service life and accuracy of the sensor in the long run. Summary of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an air valve with a pipeline leakage monitoring function.
[0004] The technical solution adopted by the utility model to solve its technical problems is: an air valve with a pipeline leakage monitoring function, including an air valve body and a float assembly arranged in the air valve body. The air valve body is provided with a valve cavity for accommodating the float assembly. The air valve body is provided with a detection hole, the detection hole communicates with the valve cavity, a detection pipeline is arranged on the detection hole, a detection valve is arranged on the detection pipeline, and a sensor for detecting the liquid in the detection pipeline is connected to the outlet of the detection valve. When the detection valve is in the open state, the physical parameters of the liquid in the detection pipeline are the same as those of the liquid in the valve cavity.
[0005] As a further improvement of this design, the sensor includes a temperature sensor and a pressure sensor. The temperature sensor is used to detect the liquid temperature in the detection pipeline, and the pressure sensor is used to detect the pressure in the detection pipeline.
[0006] As a further improvement of this design, a cleaning valve is arranged on the detection pipeline at the outlet of the detection valve, and a cleaning pipeline is arranged at the outlet of the cleaning valve.
[0007] As a further improvement of this design, the cleaning valve is an electromagnetic valve, and the temperature sensor, the pressure sensor and the cleaning valve are all communicatively connected to a data acquisition and remote control module.
[0008] As a further improvement of this design, the detection valve is a manual valve. A detection tank is connected to the outlet of the detection valve. The detection tank includes a tank body and a cover plate provided on the tank body. The interior of the tank body is a tank chamber. An outlet is provided at the top of the tank body. The cover plate is used to seal the outlet of the tank body. The cover plate is detachably connected to the tank body. The detection ends of the pressure sensor and the temperature sensor are both located in the tank chamber. The bottom of the tank body is connected to the inlet of the cleaning valve. The connection port between the detection valve and the detection tank is located at the top of the tank chamber.
[0009] The beneficial effects of the present utility model are as follows: By providing a detection valve on the air valve, when a sensor needs to be installed, the sensor is installed on the pipeline at the outlet of the detection valve, and after installation, the detection valve is opened. If there is no need to install a sensor, just close the detection valve, which has no impact on the air valve body; the installation method is simple and flexible, and it is convenient for later maintenance; there is no need to drill holes in the pipeline, and there is no risk of pressure, etc. Brief Description of the Drawings

Specific Embodiments
[0014] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments, in which the schematic embodiments and descriptions are only used to explain the present utility model, but not to limit the present utility model. Embodiment
[0015] Please refer to Figure 1, this embodiment provides an air valve with a pipeline leakage monitoring function, including an air valve body 1 and a float assembly 11 arranged inside the air valve body 1. The air valve body 1 is provided with a valve cavity 2 for accommodating the float assembly 11. The air valve body 1 is provided with a detection hole 12, and the detection hole 12 communicates with the valve cavity 2. A detection pipeline 4 is arranged on the detection hole 12, and a detection valve 3 is arranged on the detection pipeline 4. The outlet of the detection valve 3 is connected to a sensor for detecting the liquid in the detection pipeline 4. When the detection valve 3 is in the open state, the physical parameters of the liquid in the detection pipeline 4 are the same as those of the liquid in the valve cavity 2.
[0016] Please refer to Figure 1 , in order to measure the main parameters of the liquid in the main pipeline, in this embodiment, the sensor includes a temperature sensor 8 and a pressure sensor 10. The temperature sensor 8 is used to detect the liquid temperature in the detection pipeline 4, and the pressure sensor 10 is used to detect the pressure in the detection pipeline 4.
[0017] Please refer to Figure 1 , in order to ensure the cleanliness of the detection end of the sensor and reduce the influence of dirt on the sensor detection, a cleaning valve 6 is arranged on the detection pipeline 4 at the outlet of the detection valve 3. A cleaning pipeline 5 is arranged at the outlet of the cleaning valve 6. By regularly opening the cleaning valve 6, the liquid at the position of the detection end of the sensor is replaced to discharge dirt.
[0018] Please refer to Figure 1 , for the convenience of automatic control, the cleaning valve 6 is an electromagnetic valve. The temperature sensor 8, the pressure sensor 10, and the cleaning valve 6 are all communicatively connected to a data acquisition and remote control module 9.
[0019] Please refer to Figure 1 , in order to improve reliability and reduce costs, the detection valve 3 is a manual valve. For the convenience of installing the sensor, a detection tank 7 is connected to the outlet of the detection valve 3. The detection tank 7 includes a tank body 72 and a cover plate 70 arranged on the tank body 72. The inside of the tank body 72 is a tank chamber 71. The top of the tank body 72 is provided with an outlet, and the cover plate 70 is used to close the outlet of the tank body 72. The cover plate 70 is detachably connected to the tank body 72. The detection ends of the pressure sensor 10 and the temperature sensor 8 are both located in the tank chamber 71. The bottom of the tank body 72 is connected to the inlet of the cleaning valve 6. The connection port between the detection valve 3 and the detection tank 7 is located at the top of the tank chamber 71, effectively preventing the generation of an air chamber in the tank chamber 71. The tank chamber 71 is cleaned through the detachable cover plate 70. The cleaning valve 6 is connected to the bottom of the tank chamber 71, and the sewage discharge is more thorough. In order to further improve the consistency of the physical properties of the liquid in the tank chamber 71 and the liquid in the main pipeline, the length of the pipeline connecting the detection tank 7 and the main pipeline is as short as possible. The detection tank 7 and the pipeline connecting the detection tank 7 and the main pipeline are both wrapped with heat insulation materials.
[0020] When the sensor needs to be involved, open the detection valve 3. The cleaning valve 6 is in the closed state. The liquid in the main pipeline enters the detection tank 7 and fills the detection tank 7. The liquid in the detection tank 7 is always in communication with the liquid in the main pipeline, that is, the liquid pressure and temperature in the main pipeline are the same as those in the detection tank 7. The sensor transmits the detected data to the detection system through the data acquisition and remote control module 9. The data acquisition and remote control module 9 regularly controls the opening of the cleaning valve 6 to realize the flushing of the detection tank 7.
[0021] When the sensor does not need to be involved, close the detection valve 3.
[0022] When there is air in the pipeline, the float ball inside the air valve will sink due to the action of gravity. At this time, the air in the pipeline can be discharged from the exhaust port. When the pipeline is full of liquid (or there is only a very small amount of air), the float ball inside the air valve will float and close due to the action of buoyancy and pressure. At this time, the water pressure in the air valve is the same as the pipeline pressure. Therefore, relevant data can be detected through instruments such as the pressure sensor 10 and temperature sensor 8 installed on the air valve. The data acquisition and remote module are used to collect relevant data and upload them to the cloud system, so as to achieve the purpose of remote monitoring.
[0023] When the monitored pressure data is abnormal, it may be caused by the abnormality of the sensor itself or the leakage of the pipeline. At this time, the solenoid valve can be opened through the remote module. At this time, water will be discharged from the cleaning pipe, so as to achieve the purpose of cleaning the foreign matters that may exist at the sensor interface. If the pressure data returns to normal, there is no pipeline leakage. If the data is still abnormal, the pipeline leakage can be judged by combining the pressure conditions at other positions of the pipeline.
[0024] In order to improve the service life of the sensor, the solenoid valve can be opened regularly to clean foreign matters. The system can be set to the automatic mode, and the solenoid valve can be switched on and off regularly according to the needs of customers.
[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present utility model.
