Abstract
The utility model discloses the valve rod of a kind of band removable seal set, including valve stem body, sealing shroud, sealing ring and retaining ring, the bottom of described valve stem body is provided with step, this step is provided with deep gouge, described sealing shroud is set in valve stem body, and the lower end of sealing shroud is arranged in the deep gouge on the step of valve stem body.The outer surface of sealing shroud is smooth surface.Sealing ring it is provided with between sealing shroud and valve stem body.Valve stem body is provided with groove, and sealing ring is arranged in this groove.The top of described valve stem body is provided with the retaining ring being positioned at above sealing shroud by screw thread, and sealing shroud is locked by this retaining ring.Valve stem body in this utility model passes through to carry out fitted seal between sealing shroud and the filler of valve gap rather than whole valve stem body directly seals with valve gap filler, simple in construction, with low cost, easy to maintenance, improves the service life of valve rod and valve.
Description
Technical field
This utility model relates to the high pressure valve in oil, natural gas extraction technical field, removable particularly to one band
Unload the valve rod of sealing shroud.
Background technology
Common valve rod is all-in-one-piece, during maintenance valve rod, needs first to be removed from system by valve, then is removed by valve,
This can cause the system underproduction.Secondly, seriously it is accomplished by more renewing valve rod if valve stem seal face scratches, but the manufacturing procedure of valve rod
Complexity, the process-cycle is long.Finally, the material of valve rod is generally alloy material, and the cost of material is the highest.Thus, above three is former
Because making the replacement cost of valve and maintenance cost the highest.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is the valve valve providing a kind of band removable seal to overlap
Bar, sealing shroud can and valve valve gap filler between carry out fitted seal rather than whole valve stem body directly and valve gap
Filler seals, simple in construction, with low cost, easy to maintenance, improves the service life of valve rod and valve.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions: one
Plant the valve rod of band removable seal set, including valve stem body, sealing shroud, sealing ring and retaining ring, described valve stem body
Bottom is provided with step, and this step is provided with deep gouge, and described sealing shroud is set in valve stem body, and the lower end of sealing shroud is arranged in
In deep gouge on the step of valve stem body, between described sealing shroud and valve stem body, it is provided with sealing ring, described valve stem body upper
Portion is provided with the retaining ring being positioned at above sealing shroud by screw thread, and sealing shroud is locked by this retaining ring.
Further, the lower end of described valve rod is T-shaped structure.
Further, the upper end of described valve stem body has the screw thread for being connected with drive mechanism.
Further, the upper end of described valve stem body has the slotted eye for being connected with drive mechanism.
Further, the outer surface of described sealing shroud is smooth surface.
The beneficial effects of the utility model are: be set with sealing shroud in (1) valve stem body, and valve rod passes through sealing shroud and valve gap
In filler carry out fitted seal, when seal failure, it is only necessary to sealing shroud is taken out from valve stem body replacing, it is not necessary to by valve
Door is removed from system, also need not be disassembled by valve, both save labour cost, saved again the plenty of time；(2) the adding of sealing shroud
Work operation is few, and machining accuracy is the highest, it is not necessary to the complicated manufacturing procedure as valve rod, greatly shortens the process-cycle, and
Sealing shroud goes for the valve of different model；(3) when changing, only change sealing shroud, retain the more expensive valve rod of material originally
Body, can save material cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
As it is shown in figure 1, the valve rod of a kind of band removable seal set, including valve stem body 1, sealing shroud 2, sealing ring 3
With retaining ring 4, the bottom of described valve stem body 1 is provided with step 11, and this step 11 is provided with deep gouge, and described sealing shroud 2 is set in
In valve stem body 1, the lower end of sealing shroud 2 is arranged in the deep gouge on the step 11 of valve stem body 1.The outer surface of sealing shroud 2 is
Smooth surface.Sealing ring 3 it is provided with between sealing shroud 2 and valve stem body 1.Valve stem body 1 is provided with groove, and sealing ring 3 is arranged at
In this groove.The top of described valve stem body 1 is provided with the retaining ring 4 being positioned at above sealing shroud 3 by screw thread, this retaining ring 4
Sealing shroud 2 is locked.
The lower end of valve stem body 1 is T-shaped structure, for the valve plate of connecting valve.
The upper end of valve stem body 1 has screw thread or slotted eye.This screw thread or slotted eye are for being connected with drive mechanism.
During installation, first sealing ring 3 is put in the groove in valve stem body 1, be then set with upper sleeve gasket 2 from top,
After install to retaining ring 4 top of valve stem body 1, to be locked by sealing shroud 2.
It is set with sealing shroud 2 in valve stem body 1, thus valve stem body 1 is by the filler in the valve gap of sealing shroud 2 and valve
Carrying out fitted seal, valve stem body 1 does not directly coordinate with the filler on the valve gap of valve, so the outer surface of valve stem body 1
There is no seal request.After valve uses a period of time, the sealing surface of sealing shroud 2 it is possible that scratch, seal failure, thus
Occur revealing, the most just can pull down retaining ring 4, sealing shroud 2 be taken out from valve stem body 1 replacing, whole valve need not be changed
Bar body, it is not necessary to removed from system by valve, also need not disassemble valve, has both saved labour cost, when saving a large amount of again
Between.It addition, the manufacturing procedure of sealing shroud 2 is few, machining accuracy is the highest, it is not necessary to the complicated manufacturing procedure as valve rod, significantly
Shorten the process-cycle, and sealing shroud 2 goes for the valve of different model；When changing, only change sealing shroud 2, protect
Stay the valve stem body that material is more expensive, it is also possible to save material cost.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in
Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
