Abstract
The utility model discloses a dismounting and mounting tool for a gas well opening protector valve core, which is applied to the dismounting and the installation of a valve core of the gas well opening protector in an oil-gas field. An upper connecting disc is parallel to and corresponds to a lower connecting disc, an upright post is vertically fixed between the upper connecting disc and the lower connecting disc, the center position of an upper plane of the upper connecting disc is welded with a screw nut, a screw rod passes through a center hole of the upper connecting disc and is connected onto the screw nut, the upper end of the screw rod is fixed with a handle, the lower end of the screw rod is welded with a rotating sleeve, a bearing and a mandrel are arranged in the rotating sleeve, the lower end of the rotating sleeve is fixed with a bearing cover, the mandrel passes through the bearing cover, the lower end of the mandrel is fixed in a center screw hole of a connecting block, the lower end of the center screw hole of the connecting block is fixed with a connecting screw rod, and the connecting screw rod can be connected with the protector valve core to be dismounted and mounted. The valve core dismounting and mounting tool has the beneficial effects that the protector valve core can be smoothly dismounted and mounted, the dismounting and mounting time is shortened, the work intensity is reduced, and the damage to the protector valve core in the dismounting and mounting process is reduced.
Description
Technical field
The utility model relates to oil gas field production gas technology field, the spool tool specially for attaching and detaching during operations such as the maintenance of particularly a kind of gas well mouth protector, maintaining, spool replacing.
Background technology
At present, at the natural gas gas production wellhead protector is installed.Protector comprises shell and spool.As the Chinese patent publication number: 2793309, the natural gas well well head that the provides safety guard that resets; Publication number: 201412106, the tree protector that provides.Because the big rise and fall of gas well single well pipeline internal pressure, gas well produces water unstable in addition, and the phenomenon of seat envelope often appears in protector, need be towards the protector operation, contain H in the gas of extraction simultaneously
2S, CO
2And salinity water; protector the bad phenomenon of protector spool can occur in long-term use; need change operation to spool; but the complicated dismounting difficulty of such protector structure; labour intensity is big; originally protector of dismounting is more than 3 hours, and in the maintenance servicing operations protector fuse spoilage more than 80%.
The utility model content
The purpose of this utility model is: a kind of gas well mouth protector spool dismantling device is provided, the protector spool can be taken out from housing, shorten the dismounting time, reduce labour intensity; Reduce the damage of protector spool in disassembly process, ensure the production of gas well safety and steady.
The technical solution adopted in the utility model is: gas well mouth protector spool dismantling device, mainly form by handle, leading screw, nut, last terminal pad, column, rotary sleeve, bearing, axle, contiguous block, connection screw mandrel and following terminal pad.It is characterized in that: it is parallel relative with following terminal pad to go up terminal pad, and vertical fixing has column between last terminal pad and following terminal pad; The planar central position is welded with nut on last terminal pad, and leading screw passes the terminal pad centre bore and is connected on the nut; Upper end at leading screw is fixed with handle, and turning handle can make leading screw can move up or down in rotation.
Lower end at leading screw is welded with rotary sleeve, and bearing and axle are arranged in rotary sleeve; Lower end at rotary sleeve is fixed with bearing cover, and axle is passed bearing cover; The lower end of axle is fixed in the center screw of contiguous block; Be fixed with the connection screw mandrel in the lower end of contiguous block center screw; Connect screw mandrel and can connect by the protector spool of dismounting, rotating threaded shaft just can drive the connection screw mandrel and move dismounting protector spool up or down.
To connect screw mandrel and have preferably in order to make neutrality, can double swerve when dismounting protector spool, on the outer wall of contiguous block, be welded with cross bar, the other end of cross bar is welded with sliding sleeve, and sliding sleeve is enclosed within on the column.Sliding sleeve and cross bar can move up and down and play centralizing function with contiguous block.
Described column has three, and three root posts are evenly distributed on terminal pad and the following terminal pad.
Described terminal pad down has centre bore, and the diameter of following terminal pad centre bore is with identical by the protector flange diameter of dismounting.
The beneficial effects of the utility model: the utility model gas well mouth protector spool dismantling device, energy is dismounting protector spool smoothly, and the protector spool is stressed evenly, steady in lifting process, and protector fuse serviceability rate is 100% in disassembly process; Shorten the dismounting time, reduce labour intensity; Reduce the damage of protector spool in disassembly process.
