Description

Technical Field

[0001] The present invention relates to the technical field of gas cut-off valves, and more specifically, to a multi-functional direct-insert type intelligent pressure regulating and cut-off valve for bottled gas. Background Art

[0002] The bottled liquefied petroleum gas pressure regulator, commonly known as a pressure reducing valve, mainly functions to automatically control the flow rate of liquefied petroleum gas at the regulating valve to ensure that the liquefied petroleum gas at the outlet can be maintained at a specified pressure level for stable supply to subsequent gas-using equipment.

[0003] The gas cut-off valve is a newly emerging safety supporting facility in the field of gas pipeline engineering. It works in coordination with a combustible gas leakage monitoring instrument. Once the monitoring instrument detects a combustible gas leakage, the cut-off valve will quickly and automatically close the main gas supply valve, immediately terminating the gas supply process, thereby effectively preventing the occurrence of serious accidents. However, the current cut-off valves on the market only have a single cut-off function and lack the ability to regulate pressure, and cannot adjust the gas pressure to adapt to different gas-using requirements.

[0004] The bottled liquefied petroleum gas pressure regulator is mainly responsible for reducing the high-pressure gas at the inlet to the rated pressure. The reduced-pressure gas is transmitted through a hose and finally delivered to gas-using terminals such as stoves for use. However, the traditional mechanical pressure regulator has limited functions. It is neither equipped with an automatic cut-off device nor a chip control system. For example, in the case of incomplete combustion of liquefied petroleum gas, gas leakage, or abnormal situations such as the connection hose falling off or being damaged, such ordinary pressure regulators are difficult to automatically shut off the gas source. In addition, they do not support intelligent connection and management with mobile phones and PCs, cannot provide corresponding prompts when the valve is opened or closed, and cannot automatically detect the real-time state of the valve. These defects have led to frequent occurrence of safety accidents such as poisoning, fire, and explosion caused by gas leakage, posing a great potential threat to the life and property safety of users.

[0005] In view of this, there is an urgent need to develop an emergency cut-off valve that integrates multiple functions such as pressure regulation, intelligent cut-off, intelligent control, and manual valve closing to fill the gaps in the existing technology, comprehensively improve the safety and intelligence level during the use of bottled liquefied petroleum gas, effectively reduce the probability of safety accidents, and provide users with a more reliable, convenient, and safe gas-using guarantee. Summary of the Invention In order to solve the above problems existing in the prior art, the present invention provides a multi-functional direct-insert intelligent pressure regulating and cut-off valve for bottled gas, which can automatically close the gas source when liquefied petroleum gas burns incompletely or leaks, and fundamentally solve accidents such as gas explosions caused by liquefied gas leakage; a manual straight valve switch is provided, which can be used to manually open or close the valve; a pressure regulating component is provided, which can adjust the pressure to a reasonable required output pressure and then transport it to gas-using terminals such as cookers for use; it realizes the integration of multiple functions such as pressure regulation, intelligent cut-off, intelligent control, and manual valve closing.

By setting the valve component and the pressure regulating component to cooperate with each other, the gas flow rate is adjusted. When producing products, it is convenient to adjust the pressure value. After reaching the standard output pressure value, the pressure regulating component can be sealed.

[0016] 2. The present invention is provided with an electromagnetic cut-off valve and an intelligent control component. In the ventilation state, when the gas induction module set in the combustible gas alarm senses gas leakage, it issues an instruction to the intelligent control component. The intelligent control component energizes the coil. After the coil is energized, it drives the magnet ring to move. The magnet ring and the iron core repel each other with the same pole. The magnet ring pushes the iron core and the valve stem to move. The movement of the valve core makes the rubber part press against the air source channel opening of the air guide pipe, closing the air source. Then, an inverse current is input to drive the magnet ring to move in the reverse direction, causing the iron core to return to its original position. To open, the button cap set at the outer end of the iron core needs to be pressed, and the button pushes the rubber part to restore ventilation. With intelligent management and control, the combustible gas alarm can be combined with mobile phones and PC terminals to achieve networked joint control. There is no leakage point in the middle of the solenoid valve, which is safer and more reliable than the valve structure closed by mechanical structure, and no power supply is required to open the valve; it solves the defect that it cannot be automatically closed during ventilation in case of gas leakage or abnormal conditions, and avoids potential safety hazards such as poisoning, fire, and explosion caused by gas leakage.

[0017] 3. The present invention is provided with a lever bracket. Gas enters the inner cavity of the valve body from the air inlet hole. When the pressure is high, the air pressure pushes the rubber diaphragm upward. The rubber diaphragm drives the suspension rod screw to lift the lever bracket. The right side of the lever bracket seals the valve nozzle, reducing the air intake; when gas enters the inner cavity of the valve body from the air inlet hole and the pressure is low, the lower magnet attracts the upper magnet, the lever bracket presses down, and the right side of the lever bracket opens the valve nozzle, increasing the air intake; it avoids too high or too low pressure output and ensures stable output pressure.
