Abstract
The present invention proposes a kind of sea valve of mud tank, solves the problem that sea cock and valve in prior art is poorly sealed.Described sea cock and valve includes handwheel, handwheel is connected with being connected lifting arm by upper end cover bearing assembly, it is cased with mounting assembly outside upper end cover bearing assembly, connect and be fixed with blind flange assembly on lifting arm, connect lifting arm lower end and be provided with lower socket valve seat, lower socket valve seat is arranged in cylinder assembly, and cylinder assembly is connected with lower shell assembly.When the present invention uses, upper end cover bearing assembly and handle synchronous axial system, now connect lifting arm and also synchronize to rise or decline, and drive lower shell valve seat to rise or fall, with lower valve base component joint when that lower shell valve seat declining so that bottom valve is closed, and its sealing effectiveness is preferable.
Description
Technical field
The present invention relates to a kind of oil equipment, be specifically related to the sea cock and valve of a kind of mud flow quantity control device.
Background technology
Sea valve of mud tank is widely used in oil drilling solid controlling blood circulation slurry tank.Existing sea cock and valve version is as shown in Figure 1.Its shortcoming is: in use for some time, during closedown, sea cock and valve is poorly sealed, can cause slurry, and when opening, bottom sea cock and valve, pulp absorbing hole is relatively big away from tank bottoms distance, causes mud fully not extract.
Summary of the invention
The present invention proposes a kind of sea valve of mud tank, solves the problem that sea cock and valve in prior art is poorly sealed.
The technical scheme is that and be achieved in that:
A kind of sea valve of mud tank, including handwheel, handwheel is connected with being connected lifting arm by upper end cover bearing assembly, it is cased with mounting assembly outside upper end cover bearing assembly, connect and be fixed with blind flange assembly on lifting arm, connecting lifting arm lower end and be provided with lower socket valve seat, lower socket valve seat is arranged in cylinder assembly, and cylinder assembly is connected with lower shell assembly.
Described blind flange assembly includes upper flange lid and lower flange lid, location bar it is connected with on upper flange lid, location bar inserts in the hole of spacer after passing lower flange lid, it is provided with connecting rod in the centre bore of upper flange lid and lower flange lid, connecting rod lower end be connected that lifting arm is connected, upper end is connected with upper end cover bearing assembly, spacer is fixed on and connects on lifting arm.
Described handwheel is connected with upper end cover bearing assembly by fastening screw nut, and upper end cover bearing assembly is provided with lubricating cup.
The bottom of descended socket valve seat is taper, and the bottom of lower shell assembly is the taper coordinated with lower socket valve seat.
When the present invention uses, upper end cover bearing assembly and handle synchronous axial system, now connect lifting arm and also synchronize to rise or decline, and drive lower shell valve seat to rise or fall, with lower valve base component joint when that lower shell valve seat declining so that bottom valve is closed, and its sealing effectiveness is preferable.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of prior art.
Fig. 2 is the schematic front view of the present invention.
Fig. 3 is the explosive view of the present invention.
Fig. 4 is the schematic perspective view of the present invention.
Wherein, 1. fastening screw nut, 2. handwheel, 3. upper end cover bearing assembly, 4. lubricating cup, 5. mounting assembly, 6. upper flange lid, 7. connects lifting arm, 8. descends socket valve seat, 9. cylinder assembly, 10. lower shell assembly, 11. securing members, 12. location bars, 13. spacers, 14. lower flange lids, 15. connecting rods.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.
As shown in Fig. 2 ~ 4, the sea valve of mud tank of the present invention includes handwheel 2, handwheel 2 is connected with being connected lifting arm 7 by upper end cover bearing assembly 3, mounting assembly 5 it is cased with outside upper end cover bearing assembly 3, connect and be fixed with blind flange assembly on lifting arm 7, connecting lifting arm 7 lower end and be provided with lower socket valve seat 8, lower socket valve seat 8 is arranged in cylinder assembly 9, and cylinder assembly 9 is connected with lower shell assembly 10.
In the present invention, it is connected by securing member 11 between cylinder assembly 9 and lower shell assembly 10, it uses process as follows: the present invention is arranged in solid controlling blood circulation slurry tank and is connected with other pipeline, the when that handwheel 2 rotating, the upper end cover bearing assembly 3 band lifting arm 7 that is dynamically connected rotates, connecting lifting arm 7 drives lower socket valve seat 8 to move up and down, instantly socket valve seat 8 runs to bottom with lower shell assembly 10 is combined when, the sea cock and valve of the present invention is closed, instantly the when that socket valve seat 8 running up, sea cock and valve is in open mode, mud is then flowed into other slurry tank or bin by cylinder assembly.
Preferred as the present invention, described blind flange assembly includes upper flange lid 6 and lower flange lid 14, location bar 12 it is connected with on upper flange lid 6, location bar 12 inserts in the hole of spacer 13 through lower flange lid 14 afterwards, connecting rod 15 it is provided with in the centre bore of upper flange lid 6 and lower flange lid 14, connecting rod 15 lower end be connected that lifting arm 7 is connected, upper end is connected with upper end cover bearing assembly 3, spacer 13 is fixed on and connects on lifting arm 7.
Its work process is as follows: 1. when rotating clockwise handle 2, and upper end cover bearing assembly 3 also follows synchronous axial system, and the connecting rod 15 being now connected on top bearing cover assembly 3 then starts slowly to rise, and be dynamically connected lifting arm 7, lower shell valve seat 8 of band rises.At this moment sea cock and valve is in open mode, and mud is then flowed into other slurry tank or bin by cylinder assembly 9.2. when rotating counterclockwise handle 2, upper end cover bearing assembly 3 also follows synchronous axial system, now connects lifting arm 7 and then starts slowly to decline, and drives lower shell valve seat 8 to decline, until fitting with lower shell assembly 10, now sea cock and valve is closed.
Described handwheel 2 is connected with upper end cover bearing assembly 3 by fastening screw nut 1, and upper end cover bearing assembly 3 is provided with lubricating cup 4.The present invention can be lubricated in time by lubricating cup 4.
As the another step of invention preferably, the bottom of descended socket valve seat 8 is taper, and the bottom of lower shell assembly 11 is the taper coordinated with lower socket valve seat 8.After being arranged to taper, the laminating between lower socket valve seat 8 and lower shell assembly 11 is the tightst, and sealing effectiveness is more preferable.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
