Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a valve-breaking structure of a gas detector. Background Technique

[0002] A combustible gas detector is a precision device designed to monitor the concentration of single or multiple combustible gases. Currently, combustible gas detectors on the market are mainly divided into two categories: catalytic type and infrared optical type. Among them, the working principle of the catalytic type combustible gas detector is based on the characteristic that the resistance of a refractory metal platinum wire changes after heating, so as to accurately measure the concentration of combustible gas.

[0003] However, the traditional combustible gas detector with a valve-breaking device is usually directly fixed on the wall by bolts during installation. This fixing method is particularly inconvenient when the device is damaged or the position needs to be adjusted. Not only is the installation process cumbersome, but it is also extremely difficult to change the position. To solve this problem, we innovatively proposed a new design of a combustible gas detector with a valve-breaking device. This design aims to simplify the installation process, improve the maintainability and flexibility of the device, and ensure that operations can be carried out quickly and conveniently when the device is damaged or the position needs to be adjusted. In view of this, in-depth research on the above problems led to the generation of this case. Content of the Utility Model

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A valve-breaking structure of a gas detector, comprising: an intake pipe, a blocking detection valve, and a drainage pipe. The blocking detection valve is connected to the intake pipe and the drainage pipe, and a detection and blocking structure is installed inside the blocking detection valve;

[0005] The detection and blocking structure includes: a partition board, a drainage shaft tube, a sealing shaft tube, a set of inflatable airbags, a set of inflatable boxes, a plurality of inflatable hoses, a concave-shaped set of airbags, a lifting extrusion plate, a lifting repelling magnet, a lifting double-wound electromagnet, a locking and limiting component, and a detector;

[0006] The partition board is installed inside the blocking detection valve. The drainage shaft tube is installed on the partition board. The sealing shaft tube is inserted into the blocking detection valve, and the drainage shaft tube is movably inserted inside the sealing shaft tube. The sleeve inflatable airbag is sleeved on the sealing shaft tube. A plurality of inflatable rubber tubes are inserted into the sealing shaft tube and the sleeve inflatable airbag. The sleeve inflatable box is sleeved on the blocking detection valve. The concave sleeve airbag is installed on the sleeve inflatable box. The lifting extrusion plate is movably inserted inside the sleeve inflatable box. The lifting repelling magnet is installed on the lifting extrusion plate. The lifting double coil electromagnet is installed on the sleeve inflatable box. The locking and limiting component is installed on the sleeve inflatable box. The detector is installed inside the blocking detection valve.

[0007] Preferably, the locking and limiting component includes: a plurality of plastic telescopic convex shaft rods, a plurality of locking magnets, a loop-shaped metal block, and a locking double coil electromagnet;

[0008] A plurality of convex locking grooves are formed on the sleeve inflatable box. A plurality of locking holes are formed on the lifting extrusion plate. A plurality of the plastic telescopic convex shaft rods are respectively movably inserted inside a plurality of the convex locking grooves and a plurality of the locking holes. A plurality of the locking magnets are respectively installed on a plurality of the plastic telescopic convex shaft rods. The loop-shaped metal block is sleeved on the sleeve inflatable box. The locking double coil electromagnet is installed on the loop-shaped metal block.

[0009] Preferably, a flow sensor is arranged on the sleeve inflatable box.

[0010] Preferably, a flame retardant layer is arranged inside the partition board.

[0011] Preferably, a plurality of heat conducting sheets are arranged on the partition board.

[0012] Preferably, a limiting rubber ring is arranged on the drainage shaft tube.

[0013] The present utility model provides a valve-breaking structure for a gas detector, which has the following beneficial effects: The valve-breaking structure of the gas detector controls the movement of the lifting repelling magnet and the locking magnet through the energization and de-energization of the electromagnet, avoiding the wear and noise that may be caused by traditional mechanical operations. This non-mechanical operation not only improves the reliability of the system but also reduces the maintenance cost. The magnetism of the electromagnet can be precisely controlled by adjusting the magnitude of the current, thereby achieving precise adjustment of the telescopic movement of the concave-shaped sleeve airbag. After the locking double-wound electromagnet is energized, it can precisely lock the position of the lifting extrusion plate to ensure the effect of limiting the drainage. Through the telescopic movement of the concave-shaped sleeve airbag, the gas is drained to the inside of the sealed shaft tube, and then the inflation airbag expands and squeezes the inflatable rubber tube, achieving efficient sealing of the drainage shaft tube. This sealing method can ensure that no gas leakage occurs during the blocking process, improving the safety of the system. Due to the fast response characteristics of the electromagnet, the entire blocking and sealing process can be completed in a short time, improving the reaction speed of the system. This mechanism adopts a series of electromagnets, airbags, and locking mechanisms. Through reasonable design and layout, the entire system structure is compact and occupies a small space. Since the magnetism of the electromagnet can be controlled by adjusting the current, this mechanism can adapt to the blocking and sealing requirements under different environments and working conditions. The main components of this mechanism are electromagnets, airbags, and locking mechanisms. These components are relatively simple and easy to replace and maintain, reducing the maintenance difficulty and cost of the system. BRIEF DESCRIPTION OF THE DRAWINGS
