Description

Technical Field

[0001] The utility model relates to a pipeline exhaust safety device. Background Art

[0002] When the pipeline is transporting water supply, drainage, heating and heating media, a certain amount of gas will exist in the pipeline at the same time. In order to ensure that the pressure inside the pipeline is always within the safety threshold, a safety device is generally installed at a certain distance on the pipeline. The gas in the pipeline can be discharged in time through the safety device to clear the pipeline and avoid accidents. In addition, when the pipeline is in operation, there will be a power outage or pump stop, and negative pressure in the pipeline will cause the pipeline to vibrate or rupture. The safety device will quickly suck air into the pipe. In order to prevent the pipeline from vibrating or rupturing or causing water hammer, a water hammer device is generally installed on the pipeline. Safety devices generally include pressure relief safety valves, exhaust valves, pressure gauges, etc. The configuration of multiple safety devices and water hammer devices on the pipeline makes installation and maintenance inconvenient, and puts higher requirements on the overall sealing of the equipment: In addition, the pressure gauges of existing safety devices are generally conventional spring tube pressure gauges, which do not have functions such as remote data transmission, and are not convenient for remote control through mobile phone APP.

[0005] Furthermore, the integrated module includes a pressure sensor, an exhaust valve, and a pressure relief safety valve, and the pressure sensor realizes a data remote transmission function through a high-precision pressure transmitter.

[0006] Furthermore, a cylindrical filter screen is disposed in the pipeline. To facilitate the installation and positioning of the cylindrical filter screen, a positioning block for quick removal is provided on the right side of the pipeline.

[0015] like Figures 1 to 4As shown, a pipeline exhaust safety device according to an embodiment of the utility model comprises a main valve body 3 for forming a connection with a pipeline 2, a valve ball 4 which can be floated in the main valve body 3, and a valve cover 6 which is arranged on the upper part of the main valve body 3. A sealing surface 31 for supporting the valve ball 4 is formed on the main valve body 3. A first exhaust channel 61 and a second exhaust channel 62 which are communicated with the inner cavity of the main valve body 3 are formed on the valve cover 6. The air inlet end of the first exhaust channel 61 corresponds to the position of the valve ball 4 and a sealing gasket 5 is arranged at the air inlet end (the sealing gasket 5 is installed at the lower part of the valve cover 6). An integrated module 7 is arranged on the second exhaust channel 62. The integrated module 7 comprises a pressure A force sensor 71, an exhaust valve 72, a pressure relief safety valve 73, and the pressure sensor 71 realizes the data remote transmission function through a high-precision pressure transmitter; a cylindrical filter 8 is also arranged in the pipeline 2. In order to facilitate the installation and positioning of the cylindrical filter 8, a positioning block 9 for quick removal is provided on the right side of the pipeline 2; the cylindrical filter 8 has a double-layer filtering structure, and the material of the cylindrical filter 8 is 304 stainless steel; the pipeline 2 is also provided with a conductivity digital electrode 1 and a connecting pipe 10, the conductivity digital electrode 1 is arranged on the front side of the cylindrical filter 8, the connecting pipe 10 is arranged on the rear side of the cylindrical filter 8, and an electric ball valve 11 is arranged on the connecting pipe 10.

[0016] The pipeline exhaust safety device has a compact structure and complete functions. It has functions of safe exhaust, anti-water hammer, filtering and sewage discharge. It is more convenient to install and maintain. The configuration of pressure sensor, conductivity digital electrode and electric ball valve ensures the needs of remote monitoring and control, and has a high degree of intelligence.

[0017] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0018] When in normal use, the valve ball 4 forms a contact seal with the sealing surface 31 due to its own gravity. When there is gas inside the pipeline 2, the gas will push the valve ball 4 upward and quickly discharge from the gap between the valve ball 4 and the sealing surface 31. Due to the large size design of the first exhaust channel 61, the exhausted gas is mainly discharged from the first exhaust channel 61, and the valve ball 4 forms a contact seal with the sealing surface 31 again due to its own gravity.

[0019] In some special cases, such as when the liquid level in the pipeline 2 is high, the valve ball 4 rises due to the buoyancy, and a contact seal is formed between the valve ball 4 and the sealing gasket 5. At this time, the first exhaust channel 61 is completely blocked. Under this condition, the gas reaches the integrated module 7 through the second exhaust channel 62 and is discharged by the exhaust valve 72. The size of the second exhaust channel 62 is relatively small. When the gas pressure in the pipeline 2 exceeds the set value, the pressure relief safety valve 73 will be opened to achieve automatic pressure relief, ensuring that the gas pressure in the pipeline 2 is within the set value; in addition, the pressure sensor 71 monitors the gas pressure in the pipeline 2 in real time. The pressure sensor 71 can achieve the on-site pressure display function. At the same time, through the role of the pressure transmitter, the measured pressure value is converted into a standard signal and transmitted to the client such as the mobile phone APP, so as to achieve remote monitoring and online alarm functions;

[0020] When water hammer occurs in the pipeline 2, the impact force of the fluid will cause the valve ball 4 to move in the main valve body 3, playing a certain role in offsetting, that is, the valve ball 4 also plays a role in preventing water hammer;

[0021] The cylindrical filter 8 can filter the particulate impurities in the pipeline 2, and the conductivity digital electrode 1 detects the blockage of the cylindrical filter 8. When it is detected that the dirt on the cylindrical filter 8 reaches a certain amount, an alarm signal is sent to the mobile phone APP (it can also be a text message to remind the user), and the opening of the electric ball valve 11 is remotely controlled through the mobile phone APP, so that the dirt is discharged in time at the discharge end of the pipe 10;

[0022] In addition, when the pressure relief safety valve 73 is abnormal, the pressure sensor 71 will detect that the pressure in the pipeline 2 exceeds the set value and send an alarm signal. The user can open the electric ball valve 11 through the mobile phone APP to also achieve the pressure relief function.

[0023] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
