A monitoring device for the opening and closing of a valve of a fire tube gas cylinder container

Abstract

This utility model relates to the field of fire safety, specifically to a monitoring device for the opening and closing of a fire detection tube gas cylinder container valve. The device includes a fire detection tube gas cylinder container valve with a small ball valve. The monitoring device also includes a micro switch and an alarm system. The micro switch is installed at the small ball valve and is used to monitor the opening and closing status of the fire detection tube gas cylinder container valve. The passive contact of the micro switch is electrically connected to the contact of the alarm system. When the small ball valve closes or opens, it triggers a state change in the micro switch. This state change is transmitted to the alarm system through the passive contact, enabling the fire control room to monitor the opening and closing status of the fire detection tube container valve in real time. This ensures that relevant personnel can promptly understand the working status of the fire extinguishing device in the event of a fire, thus allowing them to take appropriate measures. This solves the problem that traditional fire detection tube container valves lack signal feedback devices for opening and closing status, making it impossible to check whether the device is in working order.

Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, and in particular to a monitoring device for the opening and closing of valves on fire detection tube gas cylinder containers. Background Technology

[0002] The heptafluoropropane temperature-sensitive self-starting fire extinguishing device is a pre-designed and assembled system with interconnected control functions, consisting of a heptafluoropropane storage container and discharge components, and an integrated design. The device comprises a heptafluoropropane container, container valve, pressure signal transmitter, fire detection tube initiator, heptafluoropropane extinguishing agent, pressure gauge, and alarm. The container stores the heptafluoropropane extinguishing agent. After assembly, the fire detection tube is installed at the top of relatively enclosed spaces such as electrical cabinets, UPS cabinets, and information control cabinets. Once the system is installed and commissioned, it is in operation. In the event of a fire, the fire detection tube ruptures due to high temperature, causing a pressure drop within the tube, activating the container valve, and releasing the heptafluoropropane extinguishing agent to extinguish the fire.

[0003] Traditional fire detection tube container valves do not have a signal feedback device for the opening and closing status, making it impossible to check whether the device is in working condition.

[0004] Therefore, there is an urgent need for a monitoring device for the opening and closing of valves on fire detection tube gas cylinder containers. Utility Model Content

[0005] To address the problem that traditional fire detection tube container valves lack signal feedback devices for opening and closing status, making it impossible to check whether the device is in working order.

[0006] This utility model provides a monitoring device for the opening and closing of a fire-detecting tube gas cylinder container valve, including a fire-detecting tube gas cylinder container valve. The fire-detecting tube gas cylinder container valve is equipped with a small ball valve. The monitoring device for the opening and closing of the fire-detecting tube gas cylinder container valve also includes a micro switch and an alarm system. The micro switch is installed at the small ball valve and is used to monitor the opening and closing status of the fire-detecting tube gas cylinder container valve. The passive contact of the micro switch and the contact of the alarm system are electrically connected.

[0007] Preferably, the micro switch is a normally closed passive contact micro switch. When the contacts of the alarm system are separated from the normally closed passive contact micro switch, the normally closed passive contact micro switch is energized.

[0008] Preferably, the micro switch is a normally open passive contact micro switch. When the contacts of the alarm system are separated from the normally open passive contact micro switch, the normally open passive contact micro switch is de-energized.

[0009] Preferably, the monitoring device for the opening and closing of the gas cylinder container valve of the fire detection tube also includes a detachably connected housing body and sleeve. The small ball valve and the micro switch are both located inside the housing body. The side wall of the housing body is provided with a waterproof joint. One end of the micro switch extends from the waterproof joint and is electrically connected to the contacts of the alarm system.

[0010] Preferably, one end of the outer casing is threadedly connected to the sleeve, and the other end of the outer casing is provided with a knob.

[0011] Preferably, a set screw is provided at one end of the outer casing near the sleeve.

[0012] Preferably, the sleeve has an external thread on the side away from the main body of the outer casing.

[0013] The beneficial effects of this invention are reflected in the fact that by setting a microswitch, when the small ball valve is closed or opened, the state change of the microswitch is triggered. This state change is transmitted to the alarm system through a passive contact, enabling the fire control room to monitor the opening and closing status of the fire detection tube container valve in real time. This ensures that relevant personnel can promptly understand the working status of the fire extinguishing device in the event of a fire, and thus take appropriate measures. It also solves the problem that traditional fire detection tube container valves lack signal feedback devices for opening and closing status, making it impossible to check whether the device is in working order.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1 A monitoring device for the opening and closing of a fire-detecting tube gas cylinder container valve includes a fire-detecting tube gas cylinder container valve, the fire-detecting tube gas cylinder container valve is equipped with a small ball valve, the monitoring device for the opening and closing of the fire-detecting tube gas cylinder container valve also includes a micro switch 1 and an alarm system; the micro switch 1 is installed at the small ball valve, the micro switch 1 is used to monitor the opening and closing status of the fire-detecting tube gas cylinder container valve, and the passive contact of the micro switch 1 is electrically connected to the contact of the alarm system.

[0018] By setting up microswitch 1, when the small ball valve closes or opens, the state change of microswitch 1 is triggered. This state change is transmitted to the alarm system through a passive contact, enabling the fire control room to monitor the opening and closing status of the fire detection tube container valve in real time. This ensures that relevant personnel can promptly understand the working status of the fire extinguishing device in the event of a fire, and thus take appropriate measures. This solves the problem that traditional fire detection tube container valves lack signal feedback devices for opening and closing status, making it impossible to check whether the device is in working order.

[0019] In some implementations, the micro switch 1 is a normally closed passive contact micro switch 1. When the contacts of the alarm system are separated from the normally closed passive contact micro switch 1, the normally closed passive contact micro switch 1 is energized.

[0020] This ensures that when the alarm system is in its normal state, i.e., when the small ball valve is closed, the normally closed contact of microswitch 1 is closed, thus preventing the alarm system from being triggered. Once the small ball valve is opened or accidentally opened, the state of microswitch 1 changes, the normally closed contact separates, the alarm system is powered on, and a signal is quickly sent to the fire control room to prompt relevant personnel to take action.

[0021] In some implementations, the micro switch 1 is a normally open passive contact micro switch 1. When the contacts of the alarm system are separated from the normally open passive contact micro switch 1, the normally open passive contact micro switch 1 is de-energized.

[0022] With the fire detection tube cylinder valve closed, the normally open contact of microswitch 1 remains open, the circuit is not energized, and the alarm system is not triggered. That is, the alarm system does not emit any signal by default until an abnormality is detected. When the small ball valve is opened, the normally open contact of microswitch 1 closes due to mechanical action, energizing the circuit and activating the alarm system. In the event of accidental opening of the fire detection tube cylinder valve or when it needs to be opened for fire extinguishing operations, a signal is quickly sent to the fire control room, prompting relevant personnel to take action.

[0023] In some embodiments, the monitoring device for the opening and closing of the gas cylinder container valve of the fire detection tube also includes a detachably connected housing body 2 and sleeve 3. The small ball valve and the micro switch 1 are both located inside the housing body 2. The side wall of the housing body 2 is provided with a waterproof connector 21. One end of the micro switch 1 extends out from the waterproof connector 21 and is electrically connected to the contacts of the alarm system.

[0024] By incorporating the housing body 2, the small ball valve and micro switch 1 are effectively protected from external environmental influences such as dust, moisture, and other potential physical damage. This contributes to improving the reliability and lifespan of the entire monitoring device. The detachable design of the housing body 2 and sleeve 3 makes the monitoring device easier to maintain and repair. The waterproof connector 21 enhances the waterproof performance of the detection device, making it suitable for outdoor or humid environments and ensuring that electrical connections will not short-circuit or malfunction due to moisture intrusion.

[0025] Preferably, one end of the outer shell body 2 is threadedly connected to the sleeve 3, and the other end of the outer shell body 2 is provided with a knob 22.

[0026] The knob 22 facilitates the connection between the outer casing 2 and the sleeve 3.

[0027] In a further preferred embodiment, the outer casing 2 is provided with a set screw 23 at one end near the sleeve 3.

[0028] Although threaded connections offer a certain degree of tightness, they may loosen under vibration, temperature changes, or long-term use. By incorporating a set screw 23, tightening the set screw 23 allows it to press against the surface of the sleeve 3 or embed into the groove of the sleeve 3, providing a mechanical locking effect. This prevents the outer casing 2 from loosening or rotating apart from the sleeve 3 due to external forces, thereby improving the stability and reliability of the overall structure.

[0029] Preferably, the sleeve 3 has an external thread on the side away from the outer casing 2.

[0030] By providing external threads, the sleeve 3 can be quickly and securely connected to other devices with internal threads, thus facilitating the placement of the microswitch 1 near the small ball valve. For example, connecting a monitoring device to a gas cylinder or other equipment can be done without the need for additional clamps or fasteners.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
