Household gas meter with leak-proof function

Abstract

The invention provides a household gas meter with a leak-proof function, the household gas meter comprises a shell, a safety mechanism is movably connected in the shell, the safety mechanism comprises a sensing assembly used for gas leakage early warning and a blocking assembly used for gas leakage automatic closing, the sensing assembly is movably connected in the shell, and the blocking assembly is used for blocking the gas leakage early warning. The blocking assembly is movably connected to the interior of the sensing assembly; a pneumatic plate rotates to enable a measuring rod to slide, the measuring rod slides to drive a friction block to slide, and the friction block slides until the friction block makes contact with a contact, so that automatic gas leakage detection is achieved, the intelligent level of the gas meter is improved, a rotary disc rotates to drive a connecting rod to rotate, the connecting rod rotates to enable a sealing plate to slide, and a flowing pipe is closed; therefore, the gas transmission channel is automatically closed during gas leakage, the safety of the gas meter is improved, the alarm gives an alarm to automatically remind a user of gas leakage, and the emergency maintenance response time of the user is shortened.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to a household gas meter with an anti-leakage function. Background technique [0002] Outside the gas meter, only a scroll wheel with numbers can be seen in the small glass window. There are also seven digits on the scroll wheel. The first four digits of the decimal point are black, and the last three digits are red. Conventional energy with serious waste of resources and serious pollution has been transformed into clean energy such as natural gas, coal gas, and even electricity. The gas meter will play its role here. Its automatic accumulation function enables those who use natural gas or pipeline gas to know how much gas they have used so that they can pay according to the cubic meters of gas consumed every month. Existing gas meters cannot automatically detect gas leakage and stop gas delivery. At the same time, existing gas meters cannot realize the automatic leakage alarm function...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned situation that the existing gas meters cannot automatically detect gas leakage and stop gas transmission, and at the same time, the existing gas meters cannot realize the automatic leakage alarm function, which causes a large safety hazard in the use of household gas meters, practicality and reliability. In order to achieve the above automatic detection, automatic shutdown, automatic alarm, safety and reliability, and practical purposes, the present invention achieves the following technical solutions: a household gas meter with anti-leakage function, including a casing, the casing A safety mechanism is movably connected inside, and the safety mechanism includes a sensing component for early warning of gas leakage and a blocking component for automatic closing of gas leakage. the interior of the component
