Background

Some infusion line systems, such as those of heating and ventilation systems or liquid cooling systems, are usually provided with a plurality of automatic exhaust valves, which are usually connected to the infusion line through exhaust lines, in order to ensure that the gas mixed into the infusion line is automatically exhausted under the premise of sealing the infusion line system, so as to ensure that the pressure in the infusion line is stable and the flow of the liquid is less fluctuated.

However, as the automatic exhaust valve ages or fails due to poor materials, uneven mounting stress, and failure of the sealing device, the automatic exhaust valve may fail, resulting in the outflow of liquid in the infusion line from the automatic exhaust valve through the exhaust line.

If the automatic exhaust valve is installed in a factory with extremely high requirements on the environmental humidity, the leakage caused by the failed automatic exhaust valve can affect the production and cause factory loss; if the automatic exhaust valve is installed in an office area, normal office of staff may be affected.

The automatic exhaust valve is usually installed in an area which is not easy to be detected, and the leakage of the automatic exhaust valve caused by failure cannot be detected immediately. Therefore, a monitoring device is needed to immediately give an alarm when the automatic exhaust valve leaks.

The monitoring device provided by the application can immediately give an alarm to remind relevant personnel to pay attention when the exhaust valve leaks, and meanwhile, the first valve body can be closed to avoid the liquid in the infusion pipeline from continuously flowing to the exhaust valve to cause further leakage.

The monitoring device provided by the application will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1, an embodiment of the present application provides a monitoring device for monitoring a leakage state of an exhaust pipe 10, wherein a first end of the exhaust pipe 10 is connected to a transfusion pipe 20, and the monitoring device includes an exhaust valve 100, a detector 200, a first valve body 300, an alarm device 400 and a control system 500.

The infusion line 20 may be an infusion line in a heating ventilation system or a liquid cooling system, or may be an infusion line for conveying non-toxic, harmless and non-volatile materials in a reaction apparatus. In some embodiments, the peripheral wall of the horizontally disposed section of the infusion line 20 is typically provided with a vent opening extending through the peripheral wall for connection to the vent line 10.

When the gas mixed into the liquid delivery line 20 flows through the portion of the liquid delivery line 20 horizontally, the gas is influenced by gravity and rises above the liquid surface of the liquid to be separated from the liquid, and at this time, the gas discharge hole may drain a part of the gas and the liquid to the gas discharge line 10.

In some embodiments, the vent line 10 is horizontally disposed such that the gas entering the vent line 10 may be above the level of the liquid entering the vent line to facilitate the venting of the gas by the vent valve 100.

In some embodiments, the vent valve 100 is connected to the second end of the vent line 10, and the vent valve 100 is in a normally open state for venting the gas entering the vent line 10. When the exhaust valve 100 can be operated normally, the exhaust valve 100 can only exhaust the gas without leaking the liquid; and when the discharge valve 100 malfunctions, the liquid may leak from the discharge valve 100.

In some embodiments, the detector 200 is electrically connected to the alarm device 400, and is configured to detect whether the exhaust valve 100 leaks and send a leak signal to the alarm device 400.

In some embodiments, the detector 200 is a leak sensor configured to send a leak signal to the alarm device 400 when a leak is detected. Referring to fig. 1, in some embodiments, the leakage sensor is disposed below the exhaust valve 100, corresponding to the position of the exhaust valve 100, and when the exhaust valve 100 leaks, liquid drops to the leakage sensor under the action of gravity, and the leakage sensor sends the leakage signal to the alarm device 400.

In some embodiments, the weeping sensor is a point weeping sensor.

Referring to fig. 2, in other embodiments, the detector 200 is a humidity sensor fixedly attached to the peripheral wall of the exhaust pipe 10 adjacent to the exhaust valve 100, and in some embodiments, the humidity sensor is detachably attached to the exhaust pipe 10 by a clamp. In some embodiments, the humidity sensor is configured to send the leakage signal to the alarm device 400 when the detected humidity is greater than a preset value.

In some embodiments, the first valve body 300 is disposed on the exhaust pipe 10 and near a first end of the exhaust pipe 10, for controlling the conduction or closing of the exhaust pipe 10. When the exhaust valve 100 works normally, the first valve body 300 is conducted; when the exhaust valve 100 malfunctions, the first valve body 300 is closed.

In some embodiments, the first valve body 300 comprises an electrically-controlled valve provided with a signal receiver, which is turned on when the annunciator receives a turn-on signal sent by the control system 500; and when the annunciator receives a closing signal sent by the control system, the electric control valve is closed.

In some embodiments, the alarm device 400 is electrically connected to the control system 500, and the alarm device 400 is configured to send an alarm upon receiving the weeping signal and to communicate the weeping signal to the control system 500.

In some embodiments, the alarm device 400 includes a first alarm and a second alarm (not shown in the figure), where the first alarm is disposed near the exhaust valve 100 to alert a worker near the exhaust valve 100 when the exhaust valve 100 leaks, for example, to sound a beep while flashing a light; and the second alarm is arranged in a remote control room to remind a worker in the remote control room to pay attention when the exhaust valve 100 leaks, and in some embodiments, the remote control room is a monitoring room of a factory, and the reminding mode of the second alarm is to sound a beep and flash light at the same time.

In some embodiments, the control system 500 is electrically connected to the first valve body 300, the control system 500 being configured to close the first valve body 300 upon receiving the weeping signal. In some embodiments, the control system 500 sends the conduction signal to the first valve body 300 in the normal working chamber of the first valve body 300 to control the first valve body 300 to conduct; and the control system 500 sends the closing signal to the first valve body after receiving the leakage signal, so as to control the first valve body 300 to be closed.

In some embodiments, the monitoring device further comprises a second valve body 600 disposed on the exhaust line 10 between the first valve body 300 and the first end of the exhaust line 10. The second valve body 600 is in an open state when the exhaust valve 100 and the exhaust pipe 10 are operated, and the second valve body 600 is closed when maintenance of the exhaust valve 100 is required.

In some embodiments, the second valve body 600 comprises a manual ball valve that is manually closed by a worker.

In some embodiments, the monitoring device operates as follows: when the vent valve 100 works normally, the gas in the infusion line 20 is discharged from the vent valve 100 through the vent line 10, and the liquid in the infusion line 20 is not discharged by the vent valve 100 even if reaching the vent line 10; when the vent valve 100 fails, the liquid in the infusion line 20 leaks from the vent valve 100 through the vent line 10, the detector 200 detects that the vent valve 100 leaks and sends a leakage signal to the alarm device, the alarm device 400 sends an alarm after receiving the leakage signal and transmits the leakage signal to the control system 500, and the control system 500 is configured to close the first valve body 300 after receiving the leakage signal.
