Abstract
The invention discloses a method for aligning a flange disc hole in process of replacing a large-diameter valve, relates to a method for aligning a valve flange disc, and in particular relates to a method for aligning a flange disc hole in a process of replacing a large-diameter valve. The method can be used for solving the problems that a bolt hole on the valve flange disc only can be aligned by manually assisting a crane through a crowbar, lots of manual labor and time are consumed and the replacement cost of the valve is increased. The method comprises the following steps of: manufacturing a plurality of conical pin shafts according to the diameter of the bolt hole of the valve flange disc; lifting the valve through the crane, and allowing the lower ends of the conical pin shafts to sequentially penetrate through the bolt hole on the valve flange disc and a bolt hole on a mounting flange disc from top to bottom, so that all the bolt holes are totally aligned; mounting bolts in the bolt hole on the valve flange disc and the bolt hole on the mounting flange disc, sequentially taking each conical pin shaft out after all the bolts are mounted, and finishing the valve replacement. The method is used for replacing the large-diameter valve.
Description
Technical field
The present invention relates to a kind of valve flanges dish aligning method, be specifically related to valve flanges dish hole aligning method in a kind of replacing large-diameter valves process.
Background technology
Changing pressure regulator valve (DN1800), hot-blast valve (DN1000), combustion valve (DN1000), during the large-diameter valves such as blank-plate valve (DN1200), because of its weight all about one ton, all is furnished with crane when pretending industry auxiliary, six people of needs reach the operation about ten hours, because crane cooperates the mobile degree of accuracy lower, valve flanges dish hole complete matching is very difficult, can only carry out centering by manually ceaselessly prizing the valve flanges dish with crowbar, each bolt hole needs manually to assist the centering alignment with crowbar, consume a large amount of manpowers and time, improved the replacing valve cost.
Summary of the invention
The present invention is for solving when changing large-diameter valves, bolt hole on the valve flanges dish can only be by manually assisting crane to carry out the centering alignment with crowbar, a large amount of manpowers and time have been consumed, improve the problem of replacing valve cost, and then proposed valve flanges dish hole aligning method in a kind of replacing large-diameter valves process.
The present invention addresses the above problem the technical scheme of taking to be: concrete steps of the present invention are as follows:
Construction bolt in step 3, the bolt hole on the valve flanges dish and the bolt hole on the mounting flange takes out each taper bearing pin successively after all bolts install, finish replacing valve.
The invention has the beneficial effects as follows: the present invention has reduced workman's labour intensity, has reduced the time of changing valve, has improved operating efficiency, reduced the crane cost of use, the present invention is simple and quick, and is reusable, and can be applicable in other parts bolt hole centering work.
Description of drawings
Fig. 1 is scheme of installation of the present invention, and Fig. 2 is the structural representation of taper bearing pin, structural representation when Fig. 3 is taper bearing pin insertion valve ring flange and the winding bolt hole of mounting flange.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, the described a kind of concrete steps of changing valve flanges dish hole aligning method in the large-diameter valves process of present embodiment are as follows:
Construction bolt in the bolt hole on step 3, the bolt hole on valve flanges dish 1 and the mounting flange 3 takes out each taper bearing pin 2 successively after all bolts install, finish replacing valve.
The specific embodiment two: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, makes a plurality of taper bearing pins 2 in the described a kind of step 1 of changing valve flanges dish hole aligning method in the large-diameter valves process of present embodiment and refer to make at least two above taper bearing pins 2.Other composition and annexation are identical with the specific embodiment one.
Claims (2)
1. change valve flanges dish hole aligning method in the large-diameter valves process for one kind, it is characterized in that: described a kind of concrete steps of changing valve flanges dish hole aligning method in the large-diameter valves process are as follows:
Step 1, make a plurality of taper bearing pins (2) according to valve flanges dish (1) bolt aperture;
Step 2, with crane valve is sling, the lower end of taper bearing pin (2) is from top to bottom passed in the bolt hole and the bolt hole on the mounting flange (3) on the valve flanges dish (1) successively, make all bolt hole all aligns;
Construction bolt in the bolt hole on step 3, the bolt hole on valve flanges dish (1) and the mounting flange (3) takes out each taper bearing pin (2) successively after all bolts install, finish replacing valve.
2. valve flanges dish hole aligning method in described a kind of replacing large-diameter valves process according to claim 1 is characterized in that: make a plurality of taper bearing pins (2) in the step 1 and refer to make two above taper bearing pins (2) at least.
