Abstract

The utility model relates to a butterfly valve for a transformer and provides the butterfly valve for the transformer with favorable service performance, long service life and low use cost. The butterfly valve comprises a valve body, a valve plate, a valve shaft, a valve cap and a limiting device. The utility model has structural key points that an annular groove is arranged in the valve body; and a sealing ring is arranged in the groove and is in liquid sealing with the outer circumferential surface of the valve plate in a closed state.

Description

The transformer butterfly valve
Technical field
The utility model relates to a kind of butterfly valve, especially is applied to the transformer butterfly valve on the transformer oil circuit.
Background technique
Need it is debugged and keeps in repair during transformer uses, and vacuumize with oiling etc., need to be provided with a plurality of butterfly valves on the oil circuit, the rotation by valve plate realizes opening and close oil circuit, and is very high to the butterfly valve seal performance requirement.At present, transformer comprises valve body, valve plate, valve shaft, valve gap with butterfly valve, and valve plate is fixedlyed connected with valve shaft and is arranged in the valve body and can relatively rotates with valve body, and the outer peripheral surface of valve plate is provided with groove, groove is equipped with seal ring, and valve gap is connected with valve body by bolt; Valve body is provided with valve shaft and rotates 90 ° of limit stoper.The transformer butterfly valve is to contact with the valve interior wall sealing by the seal ring on the valve plate to realize cutting out of valve.There is following shortcoming in the transformer of this structure with butterfly valve: 1, limit because of seal ring is subjected to valve plate thickness, the valve plate seal ring that is installed in the valve plate groove is thinner, easily deform in the using process even come off, cause valve closing not tight, influence usability, also influence replacement of component on the oil circuit piping; 2, steps such as valve, transformer oil filtration are drained the oil, changed to the transformer butterfly valve that comes off and must more renew when the valve plate seal ring through transformer, just can restart work, influences working efficiency, the user cost height; 3, short working life because of product, influence the Security of transformer operation.
The model utility content
The utility model is exactly at the problems referred to above, and the transformer that a kind of usability is good, the life-span is long, user cost is low butterfly valve is provided.
For achieving the above object, the utility model adopts following scheme, and the utility model comprises valve body, valve plate, valve shaft, valve gap and limit stoper, and its structure outline is to be provided with in the valve body annular groove, seal ring is set, the valve plate outer peripheral surface liquid sealing under seal ring and the closed condition in the groove.
The model utility beneficial effect
The utility model adopts in the valve body and is provided with annular groove, seal ring is set, the valve plate outer peripheral surface liquid sealing under seal ring and the closed condition in the groove; This structure is with valve body ring structure to be set to have replaced the structure that seal ring was set originally on valve plate, and the seal ring size no longer is subjected to the restriction of valve plate thickness, can be provided with as required, and the intensity height is difficult for deforming or coming off, and usability is good, and life of product is long; Avoid frequent replacing, enhanced productivity, saved user cost; Improved the Security of transformer operation simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model comprises valve body 7, valve plate 4, valve shaft 5, valve gap 1 and limit stoper 2, is provided with annular groove 6 in the valve body 7, and seal ring 3 is set in the groove 6, the valve plate 4 outer peripheral surface liquid sealings under seal ring 3 and the closed condition.
Annular groove 6 in the valve body 7 is a dovetail groove; This spline structure can make seal ring 3 fix more firmly.
