In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a change valve sealing device in pit that can change the case in the pit and seal, replace the case to change bench vice, operate more swift is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a change valve sealing device in pit, includes the valves body, locates valves body wherein fixed cover and the locking bolt of one side, the internal diameter of fixed cover matches with the case external diameter in the valves body, locking bolt installs the lateral part and the downthehole formation locking structure that the screw thread end got into fixed cover at fixed cover.
Basically, fixed cover passes through the mounting panel to be fixed in one of them side of valves body, the mounting panel passes through a plurality of bolt fastening at the lateral part of valves body, fixed cover with the mounting panel welded fastening.
Basically, the fixed sleeve is vertically arranged or horizontally arranged.
Basically, one side of the valve group body is provided with at least two fixed sleeves and matched locking bolts.
Basically, the other side of the valve group body is also provided with at least one fixed sleeve and a matched locking bolt.
Basically, fixed cover passes through the mounting panel to be fixed in one of them one side of valves body, the lateral part that corresponds the valves body on the mounting panel sets up a plurality of perforation, the mounting panel is hung and is established the lateral part of valves body, fixed cover with mounting panel welded fastening.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses fixed cover and locking bolt of fixing at the lateral part of valves body replace the function of bench vice, the hole of fixed cover is the round hole of matcing the case, the case can perfectly insert fixed cover, then through locking bolt from the lateral part with the case top lock die tightly, spare parts such as sealing of change case that just can be convenient, the problem that circular case is difficult to the maintenance under the condition that lacks the instrument has been solved, it has can change the case in the pit sealed, replace the case to change bench vice, the operation advantage that is more swift.
Drawings
Fig. 1 is a schematic structural view of the downhole replacement valve sealing device of the present invention.
Fig. 2 is a right side view of fig. 1.
In the figure: 1. a valve block body; 2. fixing a sleeve; 3. locking the bolt; 4. a valve core; 5. mounting a plate; 6. and (4) bolts.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1 and 2, the sealing device for the underground replacement valve comprises a valve group body 1, a fixed sleeve 2 and a locking bolt 3, wherein the fixed sleeve 2 and the locking bolt 3 are arranged on one side of the valve group body 1, the inner diameter of the fixed sleeve 2 is matched with the outer diameter of a valve core 4 in the valve group body 1, and the locking bolt 3 is arranged on the side part of the fixed sleeve 2, and a threaded end of the locking bolt enters a hole of the fixed sleeve 2 to form a locking structure.
Specifically, fixed cover 2 passes through mounting panel 5 to be fixed in one of them side of valves body 1, mounting panel 5 passes through a plurality of bolts 6 to be fixed at the lateral part of valves body 1, fixed cover 2 with mounting panel 5 welded fastening, fixed cover 2 can design for vertical setting or level setting according to the demand of different occasions.
In this embodiment, one side of the valve group body is provided with two fixed sleeves and a matched locking bolt, and the valve group body can be designed in a plurality of sizes and can be set according to the size of the valve group body.
The working principle is as follows: valve element and installation sealed position in the valves body 1 are circular, in the in-process of change and maintenance, the instrument that generally needs the bench vice class presss from both sides tightly just can the operation, in the above-mentioned embodiment, adopt the locking structure of fixed cover 2 and locking bolt 3 conduct bench vice, valves body 1 is as the bearing structure of bench vice, when the sealed needs of case are changed, take out the case, the button head inserts in fixed cover 2, locking bolt 3 locks from the lateral part, then open the case through instruments such as spanners, install after changing the seal again, unblock locking bolt, then pack the valves body back with the case, accomplish whole maintenance process, whole process is swift, and is convenient, need not to go out the well, do not rely on the bench vice, do not influence production efficiency.
In other embodiments, at least one fixing sleeve and a matched locking bolt are also arranged on the other side of the valve group body.
In other embodiments, the fixed sleeve is fixed on one side of the valve group body through the mounting plate, a plurality of through holes are formed in the mounting plate corresponding to the side portion of the valve group body, the mounting plate is hung on the side portion of the valve group body, the fixed sleeve and the mounting plate are fixed in a welding mode, the mode is suitable for a scene that the valve group body is not suitable for being additionally provided with too many objects, quick loading and unloading are achieved through the hanging mode, and efficiency is high.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
