Abstract
A kind of protective tooling for installing anti-fugacity filler, including a soft bushing, it is lining in valve cover hole in soft bushing, soft bushing inner diameter is less than valve cover hole internal diameter, is provided with crawl section on soft bushing, crawl section is located at outside valve cover hole, convenient for soft bushing to be axially disengaging from valve cover hole, valve rod is packed into soft bushing for crawl section, offers divisional plane on soft bushing, soft bushing is removed from valve rod after being axially disengaging in valve cover hole, through divisional plane.The beneficial effects of the present invention are: using soft bushing, internal diameter is less than valve cover hole internal diameter, when installing valve rod, guarantees that valve rod is contacted with valve cover hole zero, valve rod is avoided to scratch, guarantee leakproofness, and soft bushing valve rod after the installation is completed, it may be convenient to removed from valve rod, reduce valve rod open and close torque, and after removing soft bushing, valve can be adapted for the harsh operating condition such as high temperature and pressure, and the scope of application is wider.
Description
Technical field
The present invention relates to protective toolings when a kind of installation valve.
Background technique
Requirement now with country to environmental protection is constantly promoted, and more and more valve users leak the fugacity of valve
Requirement is proposed, anti-fugacity filler is exactly a kind of sealing technique for allowing valve rod position to reduce fugacity leakage.
Common filler is all after installing valve rod, then one by one or one group is installed to valve rod and filler by filler
Between letter, still, in order to make can to fit closely between filler, gap is reduced, the sealing performance of filler is promoted, enhances anti-loss
Property；When anti-fugacity filler is installed, first filler is installed in stuffing-box, then using filler inner hole as guide-localization, by valve rod
It is screwed in filler from bonnet lower, in this way, valve rod and the friction of valve deck inner hole in installation process, are easy to be pulled by valve deck inner hole, one
Denier valve rod is pulled, and sealing will fail, and is leaked.
Summary of the invention
The purpose of the present invention is to provide a kind of structure is simple, can effectively prevent when anti-fugacity filler is installed, valve rod quilt
The protective tooling that valve deck is pulled.
The technical solution adopted by the present invention to solve the technical problems is a kind of anti-nurse for installing anti-fugacity filler
It fills, including a soft bushing, is lining in valve cover hole in soft bushing, soft bushing inner diameter is less than valve cover hole internal diameter, soft lining
It putting on and is provided with crawl section, crawl section is located at outside valve cover hole, and crawl section is convenient for for soft bushing being axially disengaging from valve cover hole,
Valve rod is packed into soft bushing, and divisional plane is offered on soft bushing, and soft bushing in valve cover hole after being axially disengaging, by dividing
Face is removed from valve rod.
Further, valve cover hole offers mounting groove, is lining in the mounting groove of valve cover hole in soft bushing.
Further, the axial length of soft bushing is 1-1.5 times of stem diameter.
Further, the quantity of divisional plane is no less than 1.
The beneficial effects of the present invention are:
1, using soft bushing, internal diameter is less than valve cover hole internal diameter, when installing valve rod, guarantees that valve rod is contacted with valve cover hole zero,
It avoids valve rod from scratching, influences leakproofness；
2, soft bushing is equipped with crawl section, facilitates and extracts it from valve cover hole central axes, and soft bushing is flexible material
It is made, divisional plane can be equipped with thereon, may make it to push aside at divisional plane, removed from valve rod convenient for it；
3, in order to control the gap between valve rod and valve cover hole, preferably guarantee the sealing performance of filler, valve cover hole opens up
There is mounting groove, be lining in the mounting groove of valve cover hole in soft bushing, so that soft bushing inner diameter is slightly less than valve cover hole unslotted portion
The internal diameter of position guarantees that there are gaps with valve deck inner hole unslotted position for valve rod, but gap is smaller；
4, the axial length of soft bushing is 1-1.5 times of stem diameter, it is ensured that valve rod has preferably during installation
Guiding performance；
5, the quantity of divisional plane is no less than 1 on soft bushing, it is ensured that and soft bushing can be removed from valve rod, point
When the quantity more than one of face, same effect also can achieve.
6, soft bushing valve rod after the installation is completed, it may be convenient to removed from valve rod, reduce valve rod open and close torque, and
After removing soft bushing, valve can be adapted for the harsh operating condition such as high temperature and pressure, and the scope of application is wider.

Specific embodiment
As shown in Figure 1, 2, a kind of protective tooling for installing anti-fugacity filler, including a soft bushing 4, soft bushing
It is lining in 4 in valve cover hole 5, soft 4 internal diameter of bushing is less than 5 internal diameter of valve cover hole, when installing valve rod 2, guarantees valve rod 2 and valve cover hole 5
Zero contact, avoids 2 bar of valve from scratching；Crawl section 6 is provided on soft bushing 4, crawl section 6 is located at outside valve cover hole 5, crawl section 6
Convenient for soft bushing 4 to be axially disengaging from valve cover hole 5, valve rod 2 is packed into soft bushing 4, offers segmentation on soft bushing 4
Face 7, soft bushing 4 are removed from valve rod 2 after being axially disengaging in valve cover hole 5, through divisional plane 7.
The scheme of optimization, valve cover hole offer mounting groove 3, are lining in the mounting groove 3 of valve cover hole 5, are convenient in soft bushing 4
The installation of soft bushing 4 positions, but the wall thickness of soft bushing 4 is small less than the depth of mounting groove 3, that is, 4 internal diameter of soft bushing
In 5 internal diameter of valve cover hole, guarantees valve rod 2 during installation, contacted with valve cover hole 5 zero.
More optimized scheme, the axial length of soft bushing 4 are 1-1.5 times of 2 diameter of valve rod, so that in installation valve rod 2
When, soft bushing 4 plays optimal guiding role.
Further scheme is that the quantity of divisional plane 7 is no less than 1, when the quantity of divisional plane 7 is 1, Ke Yicong
Soft bushing 4 is pushed aside at divisional plane 7, so that soft bushing 4 is unloaded from valve rod 2, when the quantity when divisional plane 7 is greater than
At 1, it can be pushed aside from any divisional plane, and unload.
In use, the first step, will be lining in valve cover hole 5, outer surface and the valve cover hole 5 of soft bushing 4 are matched in soft bushing 4
It closes；Valve rod 2 is fitted into soft bushing 4 by second step using soft 4 inner hole of bushing as positioning and guiding, and soft 4 internal diameter of bushing is less than
5 internal diameter of valve cover hole guarantees in 2 loading procedure of valve rod that valve rod 2 and valve cover hole 5 zero rub；Third step, between valve rod 2 and valve deck
It is packed into filler 1；Soft bushing 4 is axially disengaging by the 4th step by crawl section 6 from valve cover hole 5；5th step, passes through divisional plane
7, soft bushing 4 is removed from valve rod 2.
