Abstract

The utility model discloses a waterproof type transformer butterfly valve and belongs to the technology of transformers. A valve body rotating shaft boss protrudes right above a center rotating shaft hole of a valve body of the butterfly valve, and the upper surface and the side face of the valve body rotating shaft boss are completely covered by an end cap. The rainproof type transformer butterfly valve comprises the valve body, a rotating shaft boss and the end cap. Due to the fact that the rotating shaft boss is added to the matching position of the center rotating shaft and the valve body, and the waterproof end cap is covered on the rotating shaft boss, rain wash can be completely prevented, and the center rotating shaft is prevented from being corroded or the oil in the transformer is prevented from being polluted due to the fact that rainwater is prevented from invading the butterfly center rotating shaft.

Description

Rain proof type transformer butterfly valve

Technical field

The utility model relates to transformer technology, particularly a kind of rain proof type transformer butterfly valve.

Background technique

At present, the device of a kind of isolating transformer oil that power transformer generally adopts is the transformer butterfly valve, and its effect is to change assembly or radiator at transformer, and plays the oil removal protective action during for the oil conservater oiling.Though but most of transformer butterfly valve can play the effect that disconnects pipeline, isolation minute oil now, can not prevent effectively that but rainwater is to the invasion of butterfly valve rotating shaft, cause the central rotating shaft of butterfly valve is caused corrosion, thereby affect the normal operation of butterfly valve or pollute transformer inner with oil.

The model utility content

In view of this, the purpose of this utility model is to provide a kind of rain proof type transformer butterfly valve, is used for preventing that the central rotating shaft of transformer butterfly valve is by rain erosion.

The utility model provides a kind of rain proof type transformer butterfly valve, be extruded with valve body rotating shaft boss directly over the place, central rotating shaft hole of butterfly valve body, and upper surface and the side of described valve body rotating shaft boss is wrapped up fully by end cap.

This rain proof type butterfly valve has valve body, rotating shaft boss, end cap, rotating shaft boss in central rotating shaft and the increase of valve body cooperation place, with and the waterproof end cap of upper parcel, can prevent completely rainwash, prevent rainwater invasion butterfly valve central rotating shaft and corrode central rotating shaft or pollute transformer inner with oil.

Description of drawings

The structure side view of the rain proof type transformer butterfly valve that Fig. 1 provides for the utility model embodiment;

The structural perspective of valve body rotating shaft boss in the rain proof type transformer butterfly valve that Fig. 2 provides for the utility model embodiment.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.

The utility model belongs to the transformer assembly, is installed on the transformer-cabinet.Its configuration is to add a valve body rotating shaft boss at transformer with butterfly valve, cooperates end cap to use, and effectively prevents invasion and then the corrosion central rotating shaft of rainwater.Transformer is played a protective role with oil.

Butterfly valve body 1, the most important main body of butterfly valve, the carrying valve plate is between connection transformer and the accessory.

Valve body rotating shaft boss 2, the bottom surface is rectangle, and upper surface middle concave both sides are slightly high, and the side is " recessed " font, as shown in Figure 2, gives prominence to directly over the place, central rotating shaft hole of butterfly valve body 1, with the moulding of butterfly valve body rheo-die-casting.With end cap 3 Spielpassung, in being wrapped in fully by end cap, can prevent effectively that rainwater from entering the central rotating shaft of butterfly valve body behind the assembling finished product.

End cap 3, upper surface is rectangle, bottom surface internal recess one cuboid as shown in Figure 1, spatial volume size and valve body rotating shaft boss 2 in the same sizes are buckled in during work on the valve body rotating shaft boss 2.The central rotating shaft hole is in the valve body top and the protection of rotating shaft boss is arranged, and end cap 3 can effectively prevent rainwater intrusion central rotating shaft when raining.

In the present embodiment, this rain proof type transformer butterfly valve increases a valve body rotating shaft boss at central rotating shaft and valve body cooperation place, and increase the end cap of a waterproof at valve body rotating shaft boss, after being fitted to each other, can play the effect that directly prevents rainwater center of impact axis hole, effectively avoid rainwater invasion butterfly valve central rotating shaft corrosion central rotating shaft or polluted transformer inner with oil.

In a word, the above is preferred embodiment of the present utility model only, is not be used to limiting protection domain of the present utility model.

Claims

1. a rain proof type transformer butterfly valve is characterized in that, be extruded with valve body rotating shaft boss directly over the place, central rotating shaft hole of butterfly valve body, and upper surface and the side of described valve body rotating shaft boss is wrapped up fully by end cap.

2. rain proof type transformer butterfly valve according to claim 1 is characterized in that, the bottom surface of described valve body rotating shaft boss is rectangle, and upper surface middle concave both sides are high, and the side is " recessed " font, with the moulding of butterfly valve body rheo-die-casting.

3. rain proof type transformer butterfly valve according to claim 2, it is characterized in that, the upper surface of described end cap is rectangle, bottom surface internal recess one rectangular space, spatial volume is consistent with described valve body rotating shaft boss with shape, be buckled in during work on the valve body rotating shaft boss, valve body rotating shaft boss is wrapped up.
