Description

Technical Field

[0001] The utility model belongs to the field of gas safety monitoring, in particular to a town gas safety monitoring device. Background Art

[0002] Gas refers to gas used as fuel, mainly including natural gas, liquefied petroleum gas, coal gas, etc. These gases are commonly used in household cooking, heating, hot water supply, industrial production and power generation. When using gas, you need to pay attention to safety matters, including ensuring good ventilation of gas equipment, regularly checking gas pipelines and equipment to prevent leaks, and not switching electrical appliances in the event of gas leaks, etc., to prevent fire, explosion or poisoning accidents. When gas enters the house, a solenoid valve is generally installed to facilitate cutting off the gas supply to ensure safety.

[0003] A Chinese utility model patent with announcement number CN207993209U discloses a town gas safety monitoring device, including a mounting groove provided on a wall, a gas leak alarm being slidably installed in the mounting groove, one side of the gas leak alarm extending out of the mounting groove, a first slide groove being provided at the top and bottom of the gas leak alarm, a clamping rod being slidably installed in the first slide groove, and one end of the clamping rod extending out of the first slide groove, and a second slide groove being provided at one end of the clamping rod located in the first slide groove. The utility model can quickly disassemble and install the gas leak alarm through the cooperation of the second bevel gear, the mounting groove, the gas leak alarm, the first slide groove, the clamping rod, the second slide groove, the connecting rod, the first spring, the clamping groove, the push rod, the threaded groove, the threaded rod, the first bevel gear, the through hole and the rotating rod, so as to facilitate the staff to inspect or replace the gas leak alarm.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the gas safety monitoring device is in use, an alarm will be sounded in case of gas leakage. When the residents are not at home, due to the lack of a device to disperse the gas indoors, the gas concentration near the gas pipeline may be too high.

[0005] To this end, those skilled in the art have proposed a town gas safety monitoring device to solve the problems raised by the background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a town gas safety monitoring device to solve the problem that the gas safety monitoring device in the prior art will alarm when gas leaks when in use, and when the residents are not at home, due to the lack of a device to disperse the gas indoors, the gas concentration near the gas pipeline may be too high.

[0007] A town gas safety monitoring device comprises a solenoid valve body, gas pipelines installed at both ends of the solenoid valve body, and an installation box slidably connected to the surfaces of the two gas pipelines, wherein a fixing component for fixing the position of the installation box is arranged on the gas pipeline, the solenoid valve body further comprises a valve stem installed thereon, and a pressure plate fixedly connected to the upper end of the valve stem, and a gas dispersion component for blowing gas is arranged in the installation box;

[0008] The gas diffusion component comprises a fan installed on the front end surface of the installation box, a mounting block installed on one side of the inside of the installation box, a switch button installed on the upper surface of the mounting block and a gas alarm installed on the bottom surface of the installation box.

[0009] Preferably, the gas alarm is electrically connected to the solenoid valve body through wires, and the fan is electrically connected to the switch button through wires.

[0010] Preferably, the fixing assembly includes an external thread opened on the surface of the gas pipeline and a nut threadedly connected to the external thread.

[0011] Preferably, sealing rings are fixedly connected to both side surfaces of the installation box.

[0012] Preferably, the lower surface of the pressing plate corresponds to the position of the switch button.

[0013] Through the above technical scheme, when in use, one of the gas pipelines is installed on the outdoor main branch pipe, and the other gas pipeline is installed on the indoor gas intake pipe. The solenoid valve body controls the gas to enter the indoor intake pipe. During normal use, the valve stem is in a stretched state. When the gas pipeline leaks gas, the gas will cause the gas alarm to alarm, thereby reminding the user of the gas leakage. After the gas alarm alarms, the valve stem will be controlled to be recovered, and the effect of closing the solenoid valve body can be achieved. When the valve stem moves downward, the pressure plate can be driven to move downward, thereby achieving the effect of starting the switch button. After the switch button is activated, the fan can be started. The rotation of the fan can blow out the leaked gas in the installation box, thereby reducing the concentration of gas near the gas pipeline and achieving a safety protection effect.

[0014] Preferably, a through slot is provided at the upper end of the installation box, a rotating plate is rotatably connected in the through slot, a hidden handle is provided on the upper surface of the rotating plate, a magnet is fixedly connected to the lower surface of the rotating plate, and an iron block is fixedly connected to one side of the interior of the installation box, and the positions of the magnet and the iron block correspond.

[0015] Through the above technical solution, when in use, the rotating plate can be rotated through the hidden handle, so that the installation box can be opened to facilitate the inspection and maintenance of the components inside it.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model installs one of the gas pipelines on the outdoor main branch pipe and the other gas pipeline on the indoor gas intake pipe. The solenoid valve body controls the gas to enter the indoor intake pipe. During normal use, the valve stem is in a stretched state. When the gas pipeline leaks gas, the gas will cause the gas alarm to alarm, thereby reminding the user of the gas leakage. After the gas alarm alarms, the valve stem will be controlled to retract, and the effect of closing the solenoid valve body can be achieved. When the valve stem moves downward, the pressure plate can be driven to move downward, thereby achieving the effect of starting the switch button. After the switch button is turned on, the fan can be started. The rotation of the fan can blow out the leaked gas in the installation box, thereby reducing the concentration of gas near the gas pipeline and achieving a safety protection effect.

[0018] 2. The utility model can rotate the rotating plate through the hidden handle, so that the installation box can be opened to facilitate the inspection and maintenance of the components inside. BRIEF DESCRIPTION OF THE DRAWINGS
