Abstract
Disclosed is a valve core vane structure for a vacuum eccentric dish valve with a diameter of less than 80mm. The valve core vane structure comprises a valve core vane, a valve handle and a combining site of the valve core vane and the valve handle; the combining site is characterized in that a circular lug boss is added at one side of the center of the valve core vane, and the valve handle threads through a radial hole of the circular lug boss and is riveted into a whole body through a pin roll. The valve core vane is simple in structure; the combining site of the valve core vane and the valve handle will not break or transform; therefore, the valve core vane can prolong the service life of the valve and improve the operation effect of a transformer.
Description
Technical field
The utility model belongs to the vacuum valve technical field, relates to the spool blade structure of a kind of latus rectum at 80 millimeters following vacuum eccentric-butterfly-valves.
Background technique
Existing latus rectum is at the spool blade structure of the vacuum eccentric-butterfly-valve below 80 millimeters, and the mating part of blade and valve rod generally adopts valve rod directly to be riveted on the blade, is connected with rivet between valve rod and the blade.Vacuum eccentric-butterfly-valve material is generally steel or aluminum alloy quality, and wherein valve body adopts aluminum alloy, and valve rod, blade adopt steel structure.This vacuum eccentric-butterfly-valve is used for being connected between transformer body and radiator, in the transformer operation with between turn(a)round, the intrinsic oil of transformer is played sealing and draining effect.Each manufacturer is for saving cost and enhancing productivity, usually select the vacuum eccentric-butterfly-valve of above material for use, and this valve in use, has the following disadvantages: directly adopt rivet to be connected between valve rod and the spool blade, at valve opening, when closing, because the pressure and the impact force of transformer oil, make valve opening and close difficultly, if undue force, valve rod and the fracture of blade joint, cause valve normally to open or to close, cause the transformer interruption of service to take place.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned deficiency at prior art, provide a kind of simple in structure, the spool blade structure is improved, it is more firm that valve rod is connected with the spool blade, normally opens, closes the vacuum eccentric-butterfly-valve spool blade structure that fracture takes place Shi Buhui at it.
The technical solution adopted in the utility model is: this latus rectum is at the valve core blade structure of 80 millimeters following vacuum eccentric-butterfly-valves, comprise spool blade, valve rod, a boss platform is fixed in the one side increase of spool blade heart portion, and be an integral body, have radial hole and pin shaft hole in the boss platform, pass the radial hole of valve rod from the boss platform, and rivet with bearing pin.
The utility model is simple in structure, simple installation, use are reliable, can stop fracture fully, therefore can prolong the working life of valve, improves the operational effect of transformer.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 4, the utility model comprises the matching part of spool blade, valve rod, spool blade and valve rod, described matching part is the radial hole 3 of spool blade heart portion boss platform 4 and the valve lever pin axis hole 6 of valve rod connection part, in the present embodiment, described matching part adopts valve rod to pass the radial hole 3 of spool blade heart portion boss platform 4, adjusting the real pin shaft hole 2 that bores on the boss platform and the pin shaft hole 6 on the valve rod of joining of installation and design size, is one with the bearing pin riveted joint.
Among Fig. 1,2, blade gabarit 1 on the spool blade, pin shaft hole 2, radial hole 3 and boss platform 4 all are aluminum casting, be the blank of one, blade gabarit 1, pin shaft hole 2, radial hole 3 and boss platform 4 are made through surperficial deburring processing after being processed by stock-removing machine.
Among Fig. 3,4, the convex latch 5 on the valve rod, valve lever pin axis hole 6, valve rod locating stud head 7 are the Steel Work of one.The convex latch 5 of valve rod, valve lever pin axis hole 6, valve rod locating stud head 7 are handled by integral surface after being processed by stock-removing machine, and the blackout processing is made.
The spool blade is connected through joining the riveted joint of lead plug axle with valve rod, becomes one, and finishes unlatching, the closing function of vacuum eccentric-butterfly-valve.
In the utility model, the spool blade cooperates with valve rod and is connected by direct rivet, change in the radial hole that valve rod passes spool blade heart portion boss platform, adjust the real pin shaft hole that bores on the boss platform and the pin shaft hole on the valve rod of joining of installation and design size, become one with the bearing pin riveted joint.
Spool blade boss is desk-top, be about to that the spool blade is original to be changed at spool blade heart portion increase boss platform with the valve rod riveting portion and process radial hole, valve rod is inserted in the radial hole of boss platform, and according to the real auger spindle hole of joining of installation and design size, after spool blade and valve rod are connected as a single entity by the bearing pin riveted joint, when vacuum eccentric-butterfly-valve proper functioning, finish unlatching, closing function.
Because the spool blade is the cast aluminium body, after increasing the boss platform on the spool blade, its intensity increases; And valve rod is a steel part, and its intensity also increases.By the change of spool blade, in the process of rotary spool blade, spool blade and valve rod are one, can finish unlatching smoothly, close operation, have guaranteed the reliable operation of transformer in the valve working process effectively.
