Description
Technical Field
The utility model relates to a transformer accessory technical field, especially a handle formula transformer butterfly valve.
Background
At present, with the increasing of the construction force of power facilities in China, in order to save energy and reduce the loss of power energy in the transmission process, the voltage grade of transmission and distribution is increased continuously, the application of a high-voltage main transformer is more and more extensive, and the butterfly valve used for heat dissipation of the transformer and opening and closing of an oil pipeline has great demand.
The transformer butterfly valve is usually installed between the oil tank and the heat sink of the oil-immersed transformer, and is used for controlling oil flow between the oil tank and the heat sink of the transformer. When the transformer works, the butterfly valve is in an open state, the oil tank and the radiating fins are unobstructed, and the transformer oil freely circulates under the action of pressure, so that the heat radiation of the transformer is ensured; when the transformer is transported or maintained and debugged, the butterfly valve needs to be closed, the oil way is cut off, and the isolation of the transformer main body from the outside is ensured. When the existing transformer butterfly valve is operated, the valve cap needs to be taken down, a special spanner is used for rotating the valve shaft for operation, and the following problems exist in the operation process: 1) a special spanner is needed to be used for rotating the valve shaft, and if a common spanner is used, the abrasion of an operation surface is easily caused, and the difficulty in opening and closing can be caused after the common spanner is used for a long time; 2) in the routine maintenance of the transformer, because of the existence of the valve cap, the state that the butterfly valve is closed or opened cannot be directly observed, the valve cap needs to be taken down every time, and the operation is inconvenient; 3) if the butterfly valve switch mark is unclear or the operator is unskilled, misoperation is easily caused, and the butterfly valve is damaged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a handle formula transformer butterfly valve, and the operating personnel of being convenient for uses, and sealing performance is good.
In order to solve the technical problem, the utility model adopts the following technical proposal.
A handle type transformer butterfly valve comprises a valve shaft arranged in a valve body, wherein a valve plate is arranged on the valve shaft, and a disc body for adjusting a rotary valve shaft is arranged at the end part of the valve shaft extending out of the valve body; the top end of the valve shaft is of a rectangular structure, and the disc body is buckled on the valve shaft of the rectangular structure; a handle convenient for rotating the disk body is arranged at the side end of the disk body; and a sealing rubber gasket for sealing is arranged between the disc body and the valve body.
Above-mentioned handle formula transformer butterfly valve, sealed cushion passes through fastening bolt and sets up the inboard at the dish body.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses a handle replaces the valve cap of butterfly valve, opens and closes the butterfly valve through rotatory handle, and the operating personnel of being convenient for operates, can also judge the state of butterfly valve simultaneously according to the state of handle, has reduced the maloperation of butterfly valve, has improved the life of butterfly valve.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention;
wherein: 1. the valve comprises a valve body, 2. a valve shaft, 3. a valve plate, 4. a butterfly body, 5. a handle, 6. a sealing rubber gasket and 7. a fastening bolt.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A handle type transformer butterfly valve is shown in figures 1-2 and comprises a valve body 1, a valve shaft 2, a valve plate 3 and a disc body 4. The valve shaft 2 is arranged in the valve body 1, the valve plate 3 is arranged on the valve shaft 2, and the disc body 4 is arranged at the end part of the valve shaft 2 and used for rotating the valve shaft 2.
The end of the valve shaft 2 extends out of the valve body 1, the disc body 4 is buckled on the valve shaft 2, and when the disc body 4 is rotated, the valve shaft 2 also rotates along with the disc body. The side of the dish body 4 is provided with handle 5, be convenient for hand rotatory dish body 4, install the handle additional on the dish body 4, with the one end extension of dish body, the valve cap through the dish body that has the handle replaces the butterfly valve, operating torque has been increased, operation spanner's effect has been played, the inner wall of dish body valve shaft department is very little with the clearance of valve shaft moreover, the handle is when rotating, the four sides of valve shaft can be the atress simultaneously, can not cause the damage to the operation face of valve shaft like this.
The end part of the valve shaft 2 is of a rectangular structure, the disc body 4 is buckled on the valve shaft 2 of the rectangular structure, the operating surface of the valve shaft is of the rectangular structure, and the handle disc body cannot be installed in different directions, so that the operating state of the butterfly valve can be conveniently observed, the operating state is closed when the handle is parallel to the valve body, and the misoperation cannot be caused when the handle is vertical to the valve body and is opened.
Be provided with sealed cushion 6 between the dish body 4 and the valve body 1, sealed cushion 6 passes through fastening bolt 7 and sets up on dish body 4 for improve the leakproofness between the dish body and the valve body.
The utility model discloses when operating the butterfly valve, only need twist grip alright, when closing the butterfly valve, with the handle rotation to with the parallel state of valve body, when opening the butterfly valve, with the handle rotation to with valve body vertically state, not only be convenient for operate, can also audio-visual state of observing the butterfly valve.
