Problems solved by technology
[0005] The first is that it caused the waste of chemicals and the loss of materials; the second was the indirect loss of the amount and pressure of the fire extinguishing system, which affected the final effect of fire extinguishing; the third was that the high-pressure chemicals sprayed from the starting port caused damage to the site (the not necessarily a fire scene), and may cause injury to personnel and equipment at the scene

The invention provides an anti-leakage switch device for a container valve used in a heptafluoropropane fire extinguishing system. The container valve is provided with a chemical communication port for communicating with a heptafluoropropane chemical bottle group, a chemical spray port for communicating with the fire extinguishing system pipeline, and a start The starting port for depressurization to spray the medicine, the pressure balance chamber of the container valve is provided with a movable pressure balance valve core, and the pressure balance valve core is provided with a valve core damping hole to make the pressure balance valve core when it is not activated. Block the medicine communication port under the action of air pressure balance, or move towards the start port to open the medicine connection port and spray the medicine when the pressure is lost. The valve core moves toward the needle blocking assembly, so that the needle blocking member blocks the damping hole of the valve core so that the medicine cannot leak from the activation port. The invention has the advantages of compact structure, convenient and flexible operation, strong versatility, high safety, low processing cost and effective leakage prevention.
Description
technical field [0001] The invention relates to a container valve leakage prevention switch device for a fire extinguishing system, in particular to a container valve leakage prevention switch device for a heptafluoropropane fire extinguishing system. Background technique [0002] In the existing fire-extinguishing system, the heptafluoropropane fire-extinguishing system packs heptafluoropropane and high-pressure gas in a pharmaceutical bottle group, and a switch device is provided between the pharmaceutical bottle group and the pipeline of the fire-extinguishing system. The switch device is provided with a pressure balance cavity, a movable pressure balance valve core is arranged in the cavity, and a valve core damping hole is arranged on the pressure balance valve core. [0003] When the fire extinguishing system is not activated, because the activation port on the switch device is sealed, it is affected by the damping hole of the valve core, so that the pressure balance v...
