Description
Technical field
The utility model belongs to valve leak recovery technique field, and in particular to a kind of cut-off disc nut fastening failure
Online fix tool.
Background technique
Existing shut-off valve is widely used in the industries such as Chemical Manufacture, water process, has a wide range of application, but due in use condition
Comprising media such as chemical material, water, steam, generally there is corrosivity, in long-term use process it is easy to appear gland and
Fastener corrosion, fastening force is insufficient, leads to shut-off valve packing leaking, influences to produce, and personal injury or environmentally friendly accident occurs in severe one.
The case where prior art are as follows:
1. equipment or technology that the prior art leaks shut-off valve are essentially blank, can not be online to shut-off valve packing leaking
Simply and effectively handled；
2. the prior art generally requires equipment downtime or pipeline cut out after replacement valve processing, damp production loss is serious,
And some shut down processing slowly, have aggravated the possibility for losing and causing accident, and cost is too high；
Utility model content
For above-mentioned problems of the prior art, a purpose of the utility model is to provide a kind of shut-off valve filler
The online fix tool of gland fastening failure.
In order to solve the above technical problems, the technical solution of the utility model are as follows:
A kind of online fix tool of cut-off disc nut fastening failure, including successively support base, jam nut, bolt top
Three parts, the support base include half rotary table of support, and the side at the both ends of half rotary table is supported to be separately connected a support rod, spiral shell

By the screw of screw rod in the application, linear motion is converted by screw to transmit pressure, realization is filled out
Expect the increase of gland fastening force.Can realize the increase of gland fastening force by rotating flat bolt simultaneously, thus be effectively treated because
Gland fastener corrodes packing leaking problem caused by fastening force deficiency or failure.
Jam nut is arranged close to support rod in the application, can resist support rod and screw rod simultaneously, prevent due to shut-off valve
Upper and lower extruding force it is too big, channel bit support rod and screw rod, extruding force can be improved.
Two support rods are set in the application, two support rods can move flexibly, while can be to shut-off valve above and below
It is formed and is squeezed.
Half rotary table of support of the application is semicircle, and the fix tool of the application and the contact surface of shut-off valve can be improved
Product, meanwhile, be conducive to semicircle rotary table and installed in the space of shut-off valve.
The utility model has the beneficial effects that
1) the application has filled up the blank of such application in the market, simply, conveniently, fastly by innovative structure design
Speed effectively handles such packing leaking problem.Lower cost for material, effect are obvious；
2) the application is directed to the characteristics of shut-off valve, devises the fix tool of a shut-off valve leakproof, effective solution
The problem of packing leaking caused by the gland fastening force of shut-off valve is insufficient.
3) the application is directed to the characteristics of shut-off valve, devises the handling implement in the operational process of a shut-off valve leakproof,
It can solve some valves that cannot cut out process system to repair online, ensure that process system runs continuity, be greatly reduced
Driving and parking expense.
4) the application is directed to the characteristics of shut-off valve, uniformly applies pressure to gland both ends, ensure that fastening balance, reaches
To good repairing effect.

Embodiment 1
As shown in Figure 1
A kind of online fix tool of cut-off disc nut fastening failure, including support base, jam nut 3, bolt top three
Part forms, and the support base includes half rotary table 1 of support, and the side at the both ends of half rotary table 1 is supported to be separately connected a support
Bar 2, bolt top are bolt arrangement, including holding nut 6 and screw rod 5, jam nut 3 close to the bottom of support rod 2, screw rod 5 with it is flat
Nut 3 is threadedly coupled and is screwed into support rod 2.
Half rotary table 1 of the support is semicircle cyclic structure.
Vertical line axial symmetry of the online fix tool about the arcuate midway point for passing through half rotary table of support.
The outer diameter of the support rod 2 is greater than the outer diameter of jam nut 3 and screw rod 5.
The internal diameter of the support rod 2 is less than the outer diameter of jam nut 3, and the internal diameter of support rod 2 is identical as the outer diameter of screw rod 5.
The holding nut 6 is welded to connect with screw rod 5.
The outer diameter of the holding nut 6 is identical as the outer diameter of support rod 2.
The thickness of the jam nut 3 is less than the thickness of holding nut 6.
Boss 4 is arranged in the top of the screw rod 5, and the diameter of the boss 4 is slightly less than the diameter of screw rod.
As shown in Figure 2
It is off the online fix tool top view of disc nut fastening failure, the both ends of semicircle rotary table are support rod
Top.Two inner holes 7 are set on the top of support rod, and the inner hole 7 is the hollow structure of support rod.
The centre of support rod is hollow, the inner wall setting internal screw thread of support rod, the outer wall setting external screw thread of screw rod.
It is the schematic diagram after being installed on shut-off valve for fix tool as shown in Figure 4
It is part-structure on shut-off valve shown in Fig. 4, the component of part from top to bottom is handwheel 8, valve rod branch on shut-off valve
Frame 9, gland 10, flange 11 wherein between handwheel 8 and valve rod bracket 9 are connected by valve rod, and fix tool is located at valve
Between bar bracket 9, gland 10.
Shut-off valve is mostly installed on production technology pipeline, due to including that chemical material, water, steam etc. are situated between in use condition
Matter generally has corrosivity, and it is easy to appear glands and fastener to corrode in long-term use process, and fastening force is insufficient, leads
Cause shut-off valve packing leaking.At this moment, the online fix tool of installation cut-off disc nut fastening failure, support base is mounted on
Shut-off valve top connects jam nut and bolt top at handle, and bolt contact completes fix tool on gland
Installation process.
The application method of the online fix tool of cut-off disc nut fastening failure of the application are as follows:
