Electromagnetic valve matched with container valve adopting positive-pressure sealing

Abstract

The invention discloses an electromagnetic valve matched with a container valve adopting positive-pressure sealing. The electromagnetic valve comprises a valve body, a front panel, a slide sleeve, a spring, a push rod, a lock cylinder, a lock nut, a 3 / 4 shaft, a cam, a half shaft, a half shaft sleeve, a U-shaped driving rod, a reset spring, a coil, an electromagnet, an electromagnetic push rod and an end cap. The electromagnetic valve matched with the container valve adopting the positive-pressure sealing has the advantages of reasonable and compact structural design, small occupation space, high operation reliability, dual purposes of electric and manual operation and the like.

Description

Technical field [0001] The invention belongs to the technical field of fire fighting equipment, and particularly relates to a solenoid valve used in conjunction with a container valve adopting a positive pressure seal. Background technique [0002] In the field of fire protection, the commonly used prefabricated heptafluoropropane fire extinguishing container valves, heptafluoropropane fire extinguishing system container valves, inert gas (IG541, IG01, IG100, IG55) fire extinguishing system container valves, and CO2 fire extinguishing system container valves use all sealing methods. It is a diaphragm type. In the event of a fire, you need to use the knife on the solenoid valve connected to it to pierce the sealing diaphragm on the container valve. After the fire extinguishing action is completed, when refilling the gas cylinder with fire extinguishing agent, you need to remove the container valve and replace the seal The diaphragm, that is to say, the sealing diaphragm is a vuln...

AI Technical Summary

Problems solved by technology

In order to solve this problem, the applicant has submitted to the Patent Office of the State Intellectual Property Office a number of patent applications for container valves that adopt positive pressure sealing and are respectively used in the above-mentioned different fire extinguishing systems. The common feature of these container valves is that There are no wearing parts, so it can be used repeatedly, but the valve set on it needs to be activated by a push rod, and there is still a lack of solenoid valves used with these container valves
