Embodiment Construction
[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] Such as Figure 1-4 As shown, a transition device for the pressure switch of a container valve. The container valve 9 includes a safety valve port 91 and a valve plug 92 provided on the safety valve port 91. The transition device includes a safety valve port 91 connected to the transition device. A valve body connector 2 and a switch connector 1 connected to the valve body connector. A channel 24 for medium circulation is formed in the valve body connector 2 along the length direction. One end of the channel 24 can be matched with the safety valve port. Connecting end 21. The outer wall structure of the connecting end is the same as the outer structure of the valv...

The invention discloses a transition device for a container valve pressure switch. A container valve comprises a safety valve opening and a valve plug arranged at the safety valve opening. The transition device comprises a valve body joint connected with the safety valve opening and a switch joint connected with the valve body joint, wherein a passage for allowing a medium to pass through is formed in the valve body joint; one end of the passage serves as a connecting end matched with the safety valve opening, and the other end of the passage serves as a seal-connection end matched with the valve plug; an air flue provided with a lower end communicated with the passage is arranged on the switch joint; a blocking piece connected with the pressure switch is arranged in the air flue; a channel communicated with the air flue is arranged at the position, corresponding to the pressure switch, of the upper end of the blocking piece; the lower end part of the blocking piece is in seal fit with the inner wall of the air flue. The transition device provided by the invention has a simple structure, is convenient to use, can be directly connected with the safety valve opening of the valve body, and realizes safe relief.
Description
Technical field [0001] The invention relates to a fire extinguishing system, in particular to a transition device for a pressure switch of a container valve. Background technique [0002] With the application of the pressure network monitoring system of the gas fire extinguishing bottle group, it has become a development trend to install pressure switches on the container valves being used in the industry. However, the fire extinguishing agent bottle group in use generally does not have a pressure switch interface, and a pressure switch cannot be installed to remotely monitor the pressure in the bottle group. Therefore, to solve this problem correctly and reliably, it is necessary to develop a transition joint. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a transition device for a pressure switch of a container valve, which can achieve safe pressure relief and is convenient for repairing the pressure switc...
