Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an intelligent safety valve for gas. Background Technology

[0002] Gas is widely used in daily life and industrial production, but safety hazards such as gas leaks also threaten people's lives and property. Therefore, valves are installed between gas pipelines and gas stoves. However, existing valves have limited functions and mainly open and close the gas path by turning a knob. Users cannot intuitively and clearly judge the status of the valve, and they cannot automatically close when there is a gas leak, which has certain shortcomings. Summary of the Invention

[0003] The purpose of this invention is to provide an intelligent safety valve for gas to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent safety valve for gas, comprising a housing, an electromagnetic valve and a circuit module installed inside the housing, an inlet connector connected to the inlet end of the electromagnetic valve, an outlet connector connected to the outlet end of the electromagnetic valve, ventilation holes provided on both parallel side plates of the housing, dust filters slidably mounted on the outer walls of the side plates with ventilation holes, two clamping plates fixedly connected to the outer walls of the side plates with ventilation holes, and sliding grooves provided on the side of the two clamping plates that are close to each other, with the two ends of the dust filters slidably mounted in the sliding grooves of the clamping plates.

[0005] Preferably, a cover plate is installed on one side of the housing, and a four-color indicator light, a switch button and a buzzer are installed on the cover plate. The cover plate has mounting slots for the four-color indicator light and the switch button to ensure a stable installation. Multiple hollow holes are provided at the location where the buzzer is installed on the housing to facilitate the sound of the buzzer. An indicator sticker is affixed to one side of the cover plate, and a battery box is provided on the side of the housing away from the cover plate for installing the power supply battery.

[0006] Preferably, the dust filter consists of a rectangular frame and a filter screen. The filter screen is fixedly installed inside the rectangular frame, which can filter the air entering the housing, reduce the impact of dust and other impurities on the gas detection sensor and internal components, and facilitate disassembly, cleaning or replacement through sliding fit.

[0007] Preferably, the circuit module also includes a communication module and a data processing and storage module for remote viewing and control of the device status via mobile phone, using ESP8266 as the Wi-Fi communication module, and supporting MQTT or HTTP / HTTPS communication protocols.

[0008] Preferably, the four-color indicator lights are green, red, yellow, and blue. The indicator sticker explains the meaning of each color: green for valve open, red for valve closed, yellow for leak, and blue for battery replacement, allowing users to easily understand the equipment status. The four-color indicator lights, switch button, buzzer, and solenoid valve are electrically connected to the circuit module. The circuit module is equipped with a gas detection sensor to detect gas leaks. When a leak is detected, the circuit module controls the four-color indicator lights to turn yellow and the buzzer to sound an alarm; the switch button controls the solenoid valve to open and close, with the corresponding indicator lights turning green and red; when the battery is low, the indicator light turns blue to indicate battery replacement.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model features a simple and compact structure. By incorporating four-color indicator lights and indicator stickers, it clearly and intuitively displays the status of the intelligent safety valve, including opening, closing, gas leakage, and battery replacement requirements. This allows users to quickly understand the equipment's operating status and take timely measures to improve gas safety. The dust filter uses a sliding installation method with a card slot, facilitating disassembly, cleaning, and replacement. It effectively filters dust and other impurities from the air, ensuring the accuracy of the gas detection sensor and the cleanliness of internal components, thus extending the equipment's lifespan. The gas detection sensor, along with the circuit module, buzzer, and four-color indicator lights, can detect gas leaks in real time. Once a leak is detected, the valve is immediately closed, and an audible and visual alarm is triggered to alert the user and reduce safety hazards. Attached Figure Description

The solenoid valve 10 is a 6V solenoid valve. The inlet end of the solenoid valve 10 is connected to an inlet connector 8, and the outlet end of the solenoid valve 10 is connected to an outlet connector 9. Vent holes 101 are provided on both parallel side plates of the housing 1 to ensure gas flow inside and outside the housing, facilitating gas detection by the gas detection sensor and heat dissipation. Dust filters 7 are slidably installed on the outer walls of the side plates of the housing 1 with vent holes 101. Two clamping plates 13 are fixedly connected to the outer walls of the side plates of the housing 1 with vent holes 101. A sliding groove is provided on the side of the two clamping plates 13 that is close to each other. The dust filters 7 are slidably installed in the sliding grooves of the clamping plates 13 at both ends. The dust filters 7 are composed of a rectangular frame and a filter screen.

[0020] Working principle: The device is connected between the liquefied petroleum gas tank and the cooker. It detects gas leaks through a gas detection sensor. When a gas leak is detected, the circuit module 11 controls the solenoid valve 10 to close and illuminates the yellow indicator light 3. At the same time, the buzzer 6 sounds an alarm. The user can control the valve opening and closing via the switch button 5. The green indicator light 3 indicates that the valve is open, and the red indicator light 3 indicates that the valve is closed. When the battery power is low, the blue indicator light 3 lights up, prompting the user to replace the battery.
