Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, specifically a gas meter protective sleeve device. Background Technology

[0002] Gas meters, as a means of metering and settlement between gas suppliers and users, accurately record the amount of gas used by users. This provides a reliable data foundation for billing between users and gas companies, ensuring that users pay according to the actual amount of gas used. To eliminate the risk of gas fires, gas meters need to be installed in conspicuous locations so that users can promptly shut off the gas in case of a leak. Currently, gas meters are all exposed externally, and are generally installed in kitchen areas. The temperature of kitchen fumes and people handling items can damage the gas meters. Therefore, we propose a gas meter protective sleeve device. Utility Model Content

[0003] The purpose of this utility model is to provide a gas meter protective sleeve device, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas meter protective cover device, including a gas meter cover, a solenoid valve fixedly installed on the top of the gas meter cover, the top inlet end of the solenoid valve being connected to a gas pipe, the bottom outlet end of the solenoid valve being connected to the inlet end of the gas meter, a gas concentration sensor fixedly installed on one vertical side of the gas meter cover, and a controller fixedly installed outside the solenoid valve.

[0005] Furthermore, an operation window is provided on the vertical front surface of the gas meter cover, and a baffle is installed on the vertical front surface of the gas meter cover via a pivot pin, the baffle matching the shape of the operation window.

[0006] Furthermore, the operation window is semi-circular in shape.

[0007] Furthermore, both the gas meter cover and the baffle are made of transparent PC material.

[0008] Furthermore, four suction cup bases are fixedly installed on the outside of the gas meter cover, and the four suction cup bases are rectangularly distributed around the outside of the gas meter cover.

[0009] Furthermore, the top of the gas meter casing has a through slot to accommodate the gas meter outlet end protruding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The gas meter cover of this application is installed outside the gas meter for external impact protection. A solenoid valve is connected in series between the gas pipe and the gas meter inlet. A gas concentration sensor detects the gas concentration. In the event of a gas leak, the solenoid valve is closed to cut off the gas supply, thus achieving the effect of automatically shutting off the gas supply in a timely manner when a gas leak occurs.

[0012] 2. The gas meter cover of this application is provided with four suction cup bases around its perimeter, which are used to attach the gas meter cover to the surface of the kitchen tile to improve installation stability. The baffle can rotate around the pivot pin to facilitate operation of the buttons on the surface of the gas meter. When not in use, the baffle blocks the operation window due to its own weight, which is used to block the operation window. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, as Figure 1-2 As shown, this utility model provides a technical solution: a gas meter protective cover device, including a gas meter cover 1, a solenoid valve 4 fixedly installed on the top of the gas meter cover 1, the top inlet end of the solenoid valve 4 being connected to the gas pipe, the bottom outlet end of the solenoid valve 4 being connected to the gas meter inlet end, a gas concentration sensor 7 fixedly installed on one vertical side of the gas meter cover 1, and a controller 5 fixedly installed outside the solenoid valve 4.

[0019] In one specific embodiment of this utility model, the top inlet end of the solenoid valve 4 is connected to the gas pipe, the bottom outlet end of the solenoid valve 4 is connected to the inlet end of the gas meter, the outlet end of the gas meter is engaged with the through groove 6, and the outlet end of the gas meter is connected to the gas equipment through the gas pipe. Gas flows from the gas pipe through the solenoid valve 4 and the gas meter, and finally reaches the gas equipment. The gas concentration sensor 7 is used to detect the gas concentration. When a gas leak occurs, the gas concentration increases, and the gas concentration sensor 7 detects that the concentration value is too high. After the controller 5 processes the detection data of the gas concentration sensor 7, it automatically controls the solenoid valve 4 to switch from the conducting state to the closed state after processing by the set program, so as to cut off the gas supply in time and avoid continuous gas leakage. Four suction cup bases 3 are set around the gas meter cover 1 to attach the gas meter cover 1 to the surface of the kitchen tile. The baffle 8 can rotate around the shaft pin 9. Rotating the baffle 8 exposes the operation window 2, which is convenient for operating the buttons on the surface of the gas meter. When not in use, the baffle 8 blocks the operation window 2 due to its own weight, which is used to block the operation window 2.

[0020] In the preferred technical solution, an operation window 2 is provided on the front vertical surface of the gas meter cover 1. A baffle 8 is hinged to the front vertical surface of the gas meter cover 1 via a pivot pin 9. The baffle 8 matches the shape of the operation window 2. The operation window 2 is semi-circular in shape. When not in use, the baffle 8 blocks the operation window 2 due to its own weight, thus sealing the operation window 2.

[0021] In the preferred technical solution, both the gas meter cover 1 and the baffle 8 are made of transparent PC material, which makes it easy to observe the gas meter readings and operating status.

[0022] In the preferred technical solution, four suction cup bases 3 are fixedly installed on the outside of the gas meter cover 1. The four suction cup bases 3 are rectangularly distributed around the outside of the gas meter cover 1. The four suction cup bases 3 are used to attach the gas meter cover 1 to the surface of the kitchen tile, thereby improving the stability of the gas meter cover 1 installation.

[0023] In the preferred technical solution, the top of the gas meter cover 1 is provided with a through groove 6 for accommodating the gas meter outlet end. The gas meter cover 1 is offset from the gas meter outlet end, so that the gas meter cover 1 can be installed in close contact with the wall.

[0024] Working principle: The solenoid valve 4 is connected in series between the gas pipe and the gas meter inlet. The gas concentration sensor 7 detects the gas concentration. When there is a gas leak, the controller 5 closes the solenoid valve 4 to cut off the gas supply. The baffle 8 is rotated to expose the operation window 2. The baffle 8 can rotate around the shaft pin 9 to facilitate the operation of the buttons on the surface of the gas meter. When not in use, the baffle 8 is blocked in the operation window 2 by its own weight to seal the operation window 2.
