Problems solved by technology

[0002] There is a butterfly valve between the transformer, the oil-invasion reactor and the radiator. The vibration generated by the operation of the equipment will cause the spool of the butterfly valve to loosen, causing the butterfly valve to not close tightly and cause leakage.
Since the butterfly valve of power distribution equipment has no control parts for the spool, and ordinary tools cannot fasten the spool of the butterfly valve, the only way to solve the problem of slow seepage is to wipe and clean it frequently
For equipment with severe oil leakage, only power outage treatment is required. The treatment process is complicated, the workload is heavy, and a lot of manpower and material resources are required.
Therefore, butterfly valve leakage is a difficult problem in the maintenance of power distribution equipment

Abstract

The invention relates to an electrician instrument, in particular to a fastener for a valve core of a butterfly valve. The fastener is characterized in that a circular tube (1) is arranged on the fastener for the valve core (6) of the butterfly valve (5); two opposite bosses (2) are arranged at one end of the circular tube (1); an inserting hole (3) is formed in the tube wall of the other end of the circular tube (1); the inserting hole (3) is matched with a wrenching rod (4). The fastener for the valve core of the butterfly valve has the beneficial effects that the two bosses of the circular tube are inserted into a groove in the annular end surface of the upper end of the valve core, the valve core can be fastened through the wrenching rod, and leakage caused by loosening of the valve core is prevented; in addition, the fastener has the characteristics of being simple in structure, convenient to operate and the like; the fastener is expected to become necessary equipment for maintaining an oil filling butterfly valve of a transformer or an oil-inrush-type reactor.

Description

technical field [0001] The invention relates to an electrical apparatus, namely a butterfly valve valve core fastener. Background technique [0002] A butterfly valve is installed between the transformer, the oil-invasion reactor and the radiator. The vibration generated by the operation of the equipment will cause the spool of the butterfly valve to loosen, causing the butterfly valve to not close tightly and leak. Since the butterfly valve of the power distribution equipment does not have the control part of the valve core, and the ordinary tool cannot fasten the valve core of the butterfly valve, the problem of slow seepage can only be solved by frequent wiping and cleaning. For equipment with serious oil seepage, only power outage treatment can be performed. The treatment process is complicated, the workload is large, and a lot of manpower and material resources are required. Therefore, butterfly valve leakage is a difficult problem in the maintenance of power distribut...
