The technical field is as follows:

the invention belongs to the technical field of intelligent buildings, and particularly relates to a safety linkage system for a gas tank.

Background art:

the gas cylinder (liquefied petroleum gas cylinder) is a cylinder for storing gas, the wall thickness of the cylinder is about 2.5 mm, the internal pressure is 0.5-1.2 MPa, the safe service life is 15 years, and the cylinder needs to be periodically checked and maintained to a cylinder detection station approved by a labor department every four years, but only a few countries have gas filling companies which can really fulfill the regulations, and most individual filling stations (points) do not work under the rules. The reason for the low number of cylinder deliveries, apart from the individual filling stations (points), is also due in part to the user himself. The main points are as follows: firstly, the gas cylinder has no account opening problem, and some users have no knowledge of common knowledge such as the regular detection of the steel cylinder. Secondly, the service life of the steel cylinder is shortened due to severe use environment, and the steel cylinder is easy to be corroded and peeled off in a humid area, so that the wall thickness of the steel cylinder is reduced. And thirdly, some users know the detection time limit, and are limited in that the detection is abandoned due to troublesome submission and the like. These problems have caused a large number of unqualified or overdue steel cylinders to become "untimely bombs" in residents' homes, which is a major safety hazard in cities. The information of related departments shows that most of the accidents of civil gas fire are caused by the use of household canned liquefied gas.

At present, the positioning of the gas tank in the prior art is an integral positioning, a mechanism for respectively positioning and mutually pairing the tank body and the valve is not provided, and the gas tank and a building are not combined together. Consequently, research and development design a gas cylinder and building linkage system that combines together, effectual prevention user cooperates building promotion user safety when dismantling the gas cylinder privately, and the effect of the dual guarantee safety of play, user and property also can detect the safety and the quantity of gas cylinder, have also played the promotion to the convenience, and practical effective is of value to the city safety development.

The invention content is as follows:

the invention aims to overcome the defects in the prior art, and develops a safety linkage system for a gas tank, so that the safety is effectively improved, and safety accidents caused by gas leakage are prevented.
