Abstract
A quick-open type access hole for a heating medium furnace belongs to the technical field of petroleum delivery equipment. The quick-open type access hole is characterized in that an annular groove is arranged on a flange plate of a contact surface of the access hole with an outer press cover, and the access hole is fixed to the press cover by the aid of two to four fixing bolts. The quick-open type access hole has the advantages that several problems are smoothly solved by means of modifying a rear access hole of the heating medium furnace, the fastening bolts are detached conveniently, detachment and installation time of the access hole is shortened, the flange press cover and an inner flange are sealed more effectively, the strength of a rotary shaft is simultaneously improved, and the flange press cover and the inner flange are positioned conveniently. In addition, overhaul time is reduced from originally one and a half hours to current 40 minutes at most, and detachment and installation workload is greatly decreased.
Description
Technical field
The utility model belongs to the oil transportation equipment technical field.
Background technology
At present, in the petroleum pipeline course of conveying, generally need oil flowed at pipeline to the petroleum pipeline heating, could normally move, and the equipment of heating is exactly the heating agent stove, therefore, improves heating agent furnace apparatus performance and normally moves extremely important, the manhole of heating agent stove need often be opened or be closed in operation and maintenance, but some drawbacks have appearred in existing manhole;
What 1, original manhole adopted is that asbestos cord is pressed in the middle of the flange gland, and run duration because flange gland inner surface is smooth, is easy to occur the gap in the middle of asbestos cord is pressed in and causes Lou cigarette phenomenon
2, dismounting and installation gland bolt are too much, and bolt is too thin, and fastening and dismounting is easy to cause the bolt distortion.Remove simultaneously and the set-up time long, strengthened the maintenance difficulty.
3, asbestos cord is not easy to be wrapped in above the bolt, and winding effect is bad, and is poorly sealed
4, locating effect, flange gland are connected the rotating shaft of usefulness with inner flange too simple and easy, is not easy to recover after drawing back the outward flange gland.
Summary of the invention
The purpose of this utility model is: a kind of heating agent stove fast-open type manhole is provided, and it can realize the enclosing cover of manhole is opened fast, sealed and effectively sealing.
The technical solution of the utility model is: on the ring flange of manhole and the contact-making surface of outer gland, have ring-shaped groove, the set bolt of manhole and gland is that 2-4 is individual.
The beneficial effects of the utility model are: by to manhole transformation behind the heating agent stove, the several problems that occur have been solved smoothly, fastening bolt is convenient to dismounting, the time that has shortened the manhole dismounting and installed, also make the sealing of flange gland and inner flange better, strengthen the intensity of rotating shaft simultaneously, be convenient to the location of flange gland and inner flange.One and a half hours repair time originally, only need now 40 minutes less than, the working strength that has significantly reduced dismounting simultaneously and installed.
Description of drawings
Fig. 1 is the utility model structure chart.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, manhole, the 2nd, groove, the 3rd, bolt, the 4th, rotating shaft bolt, the 5th, outer gland, the 6th, heat preservation rock.
Fastening bolt in the past is a stove bolt, the stove bolt that general each manhole uses is all more than 4, and after improving, fastening bolt is become big fastening bolt 3, quantity reduces to below 4, and bolt 3 diameters are big, and it is faster to mount and dismount outer gland 5 speed, the fastening pressure of bolt 3 is bigger, has increased sealing.Processed groove 2 with the gland contact-making surface in the manhole 1, the graphite rope is inlayed in the groove 2, groove 2 is convenient to the installation of graphite rope, has outside the outstanding plane of graphite rope of half.Outer like this gland 5 compresses the graphite rope and has played good sealing function.
Claims (1)
1. a heating agent stove fast-open type manhole comprises manhole, it is characterized in that: on the ring flange of manhole and the contact-making surface of outer gland, have ring-shaped groove, the set bolt of manhole and gland is that 2-4 is individual.
