Abstract
The utility model relates to a butterfly valve switch lengthening device used for implementing opening and closing of a tank bottom butterfly valve in a mud tank in oil field work, which comprises an upper flange, a long shaft, a support pipe, an inner hexagonal sleeve, an outer hexagonal sleeve and a lower flange. The outer hexagonal sleeve is connected with a shaft of a butterfly valve, the inner hexagonal sleeve is connected with the outer hexagonal sleeve, the long shaft is connected with the inner hexagonal sleeve, and the upper end of the long shaft is welded with a hexagonal bolt. The support pipe is arranged outside the long shaft, and the upper flange and the lower flange are arranged at the upper end and the lower end of the support pipe. A seam of the upper flange and a seam of the lower flange are sealed via asbestos gaskets. Compared with the prior art, the tank bottom valve switch lengthening device has the advantages of simple structure and convenient operation. Additionally, a seamless pipe used as the support pipe for the tank bottom butterfly valve and a tank face portion not only solves a sealing problem but also realizes connection.
Description
Technical field
The utility model relates to and a kind ofly is used in the slurry tank of field operations implementing that the switch of butterfly valve adds growth device at the bottom of the switch jar.
Background technique
During the slurry tank operation, the butterfly valve commonly used at the jar end is covered by mud, in order on jar, to handle the switch of tank bottom valve, need be lengthened to a jar face to switch gear, with be implemented in jar operation requirement, at present the switch of jar end standard butterfly valve rotates by turbine and worm and realizes, and is full of mud in the jar during slurry tank work, and it is not too convenient to operate.
Summary of the invention
The purpose of this utility model provides a kind of tank bottom valve switch and adds growth device, and is simple in structure, easy to operate.
For achieving the above object, the utility model is achieved through the following technical solutions:
The tank bottom valve switch adds growth device, comprise upper flange, major axis, support tube, interior six sides cover, outer six sides cover, lower flange, outer six sides cover is connected with the axle of butterfly valve, and interior six sides cover is connected with outer six sides cover, major axis is connected with interior six sides cover, major axis upper end and hex head bolt welding; Support tube is arranged at the major axis outside, and two ends are provided with upper flange and lower flange up and down.
The slit of described upper flange and the slit of lower flange seal by asbestos washer.
Compared with prior art, the utility model has the advantages that: simple in structure, easy to operate, jar end butterfly valve is made support tube with a jar face portion with weldless tube, has not only solved sealing problem but also realized connection.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, the tank bottom valve switch adds growth device, comprise upper flange 6, major axis 7, support tube 4, interior six sides cover 3, outer six sides cover 2, lower flange 1, outer six sides cover 2 is connected with the axle 12 of butterfly valve, interior six sides cover 3 is connected with outer six sides cover 2, major axis 7 and interior six sides cover, 3 welding, major axis 7 upper ends and hex head bolt 5 welding; Support tube 4 is arranged at major axis 7 outsides, and two ends are provided with upper flange 6 and lower flange 1 up and down.The slit of the slit of upper flange 6 and lower flange 1 is by asbestos washer 11 sealings.
Realize the switch of butterfly valve by the rotation of major axis 7, the workman rotate on the jar face hex head bolt 5 control jar at the bottom of the switch of butterfly valve, operation is easily.
