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
The present invention relates to a kind of electrical apparatus, i.e. a kind of butterfly valve core fastener.
Background technology
Transformer and oil are invaded between formula reactor and radiator and butterfly valve are housed, and equipment runs the vibrations produced can cause loosening of butterfly valve core, causes butterfly valve to be not closed completely and seepage.Butterfly valve due to controller switching equipment does not have the control assembly of spool, and general tool cannot carry out fastening to butterfly valve core again, so the method for frequent wiping and cleaning can only be taked to solve ooze problem slowly.The equipment serious to oil impregnate only carries out power failure process, and its complex disposal process, workload are large, need a large amount of man power and materials.Therefore, butterfly valve seepage is a difficult problem in the middle of controller switching equipment is safeguarded.
Summary of the invention
The object of this invention is to provide one can fastening butterfly valve core, prevents the specific purpose tool of butterfly valve seepage.
Above-mentioned purpose is realized by following technical scheme: develop a kind of butterfly valve core fastener, be characterized in: described butterfly valve core fastener has a pipe, one end of pipe is provided with two relative boss, and the tube wall of the pipe other end is provided with jack, and jack matches with tommy bar.
Match with the annular end face of spool upper end in one end of described pipe, two fit depressions on described two boss and spool annular end face.
The long 115mm of described pipe, external diameter 21mm, internal diameter 16mm, thickness of pipe wall 2.5mm, boss height 4mm, socket diameter is 10mm, and above-mentioned scale error is less than 1%.
The invention has the beneficial effects as follows: inside the groove of two of pipe boss insertion spool upper end annular end faces, namely by the fastening spool of tommy bar, prevent spool loose leaky, and it is simple to have structure, the feature such as easy to operate, is expected to become transformer or oil and invades the indispensable equipment that the oil-filled butterfly valve of formula reactor safeguards.
Accompanying drawing explanation
Fig. 1 is a kind of front view of embodiment;
Fig. 2 is the left view of this embodiment;
Fig. 3 is the top view of this embodiment;
Fig. 4 is the occupation mode schematic diagram of this embodiment.
Visible in figure: pipe 1, boss 2, jack 3, tommy bar 4, butterfly valve 5, spool 6.
Detailed description of the invention
Fig. 1 Fig. 2 Fig. 3 describes a kind of butterfly valve core fastener, and its main body is a pipe 1, and one end of pipe 1 is provided with two relative boss 2, and the tube wall of the other end of pipe 1 is provided with jack 3, can insert a tommy bar 4 inside jack 3.Composition graphs 4 is visible: match with the annular end face of spool 6 upper end in one end of pipe 1, two boss 2 and two fit depressions on spool 6 annular end face.Invade the structure of the oil-filled butterfly valve of formula reactor according to current transformer or oil, the long 115mm of pipe of this butterfly valve fastener, external diameter 21mm, internal diameter 16mm, thickness of pipe wall 2.5mm, boss height 4mm, socket diameter is 10mm, and above-mentioned scale error is less than 1%.
Occupation mode as shown in Figure 4, is inserted the boss 2 of pipe 1 groove of butterfly valve core both sides, then is twisted pipe with tommy bar, the spool loosened can be tightened, valve precision is improved, there will not be leakage of oil.
