[0042] The first method of forming the assembly joint of the gas density relay capable of preventing misoperation of the present invention comprises the following steps:
[0043] A1. Form interconnected relay air passages, switch air passages and self-sealing valve air passages on the assembly joints, and form relay interface seats, switch interface seats and self-sealing valve air passages correspondingly one by one. Self-sealing valve interface seat;
[0044] B1. A self-sealing valve device is installed in the air passage of the self-sealing valve. The self-sealing valve device includes a self-sealing valve sleeve installed on the self-sealing valve interface seat at the front, a valve core guide fixed at the front of the inner cavity of the self-sealing valve sleeve, and a self-sealing valve located at the front of the self-sealing valve. A self-sealing spool that can move axially in the inner cavity of the sleeve, a self-sealing spring located between the spool guide and t...

The invention discloses a forming method for an assembling connector of a gas density relay capable of preventing the misoperation. The method comprises the following steps of: forming a relay air passage, a switch air passage and a self-sealing valve air passage, which are communicated with one another, on an assembling connector, arranging a self-sealing valve device in the self-sealing valve air passage, arranging a plugging element at the rear end part of a self-sealing valve sleeve, arranging an inflating transitional connector capable of entering the assembling connector through the self-sealing valve device, and arranging a verifying transitional connector which can enter the assembling connector through the self-sealing valve device. The assembling connector formed through the method can be conveniently inflated on the same position, the density relay can be verified without dismounting the density relay and additionally opening and closing the air passage by an operator, and the sealability and safety of a sulfur hexafluoride electrical switch can be guaranteed.
Description
technical field [0001] The invention relates to a method for forming an assembly joint of a gas density relay, in particular to a method for forming an assembly joint of a gas density relay capable of preventing misoperation. Background technique [0002] The sulfur hexafluoride gas density relay is used to detect the change of the sulfur hexafluoride gas density in the sulfur hexafluoride electrical switch, and its performance directly affects the reliable and safe operation of the sulfur hexafluoride electrical switch. The sulfur hexafluoride gas density relay installed on the site does not operate frequently, and after a period of time, it often has the phenomenon of inflexible action or poor contact of the contacts, and some may also have poor temperature compensation performance. Cause the sulfur hexafluoride gas density relay to malfunction. Therefore, the test regulations stipulate that each unit that uses sulfur hexafluoride electrical switches should regularly cali...
