Abstract
The utility model discloses a pipe-end temporary plugging flange which can be quickly disassembled and assembled for steel pipeline construction. The pipe-end temporary plugging flange is divided into a head end flange and a tail end flange of the pipe segment, and is used pairwise. The head end flange is composed of a pressure meter, an air inlet pipe, a flat flange, a flange bolt, a seal ring, a loose flange and a puller bolt. The loose flange is permanently installed on the port of the pipeline via the puller bolt, and the flat flange and the loose flange are fixedly connected into integration by the flange bolt. The tail end flange needs no air inlet pipe, however, other components which are the same with the head end flange are also arranged on the tail end flange. Due to the fact that the conventional welding method is not needed any more to install, the installation is convenient, and the damage can not be created on the bevel of the pipe end. The pipe-end temporary plugging flange has the advantages of labor saving, time saving, material saving, flexibility, and convenience. The pipe-end temporary plugging flange can also be repeatedly used, can quicken the construction progress and can reduce the work cost.
Description
The utility model relates to the interim blocking device of pipe end in the steel pipe construction, particularly a kind of non-welding quick-mounting shutoff flange.
In the pipeline construction, under pressure testing or some situation, need the interim shutoff in the two ends of every segment pipe.Past is adopted the temporary transient shutoff of way of the blind plate of burn-oning for many years always, when pressure testing finishes or carry out next procedure, the shutoff blind plate is sliced off again, and again the pipe end groove is handled well.This way is time-consuming but also waste material not only, has not only influenced construction speed but also increased engineering cost, and is only for a segment pipe also will draw cutting equipment, very inconvenient sometimes.
The purpose of this utility model just is the shortcoming and defect part at prior art, and a kind of non-welding quick-mounting shutoff flange that is exclusively used in the steel pipeline construction is provided.Both can load onto fast, can unload fast again, and can repeatedly use, the saving of work and time material-saving, very flexible.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.This flange is divided into head end flange and terminal flange, and the head end flange is made up of pressure gauge, suction tude, face-flange, flange bolt, seal ring, loose flange and puller bolt.Pressure gauge and suction tude all are installed on the face-flange, and loose flange is fixedly mounted on pipe end by puller bolt, by flange bolt face-flange and loose flange are connected to a fixed one.Terminal flange does not need suction tude, and all the other are identical with the head end flange.
In order further to improve sealability, loose flange has a circular groove near the outside at tube wall place, and seal ring is housed in the groove, and face-flange is equipped with an annular boss in corresponding positions, can compress seal ring after installing, and has good seal action.
The utility model and prior art contrast major advantage are: do not need welding just can install, only need one wrench got final product, so make things convenient for again fast, and the pipe end groove had no infringement, need not to go again the repair process groove, also no longer slice off the waste steel, reached saving of work and time material-saving and convenient, flexible purpose fully, but both accelerating construction progresses can reduce engineering cost again, this flange can repeatedly use as special-purpose construction equipment, so overall economic efficiency is higher.
Accompanying drawing is a user mode schematic representation of the present utility model.Among the figure, the 1st, pressure gauge, the 2nd, suction tude, the 3rd, plane dirt orchid, the 4th, seal ring, the 5th, loose flange, the 6th, flange bolt, the 7th, puller bolt, the 8th, steel pipeline.
Details are as follows to embodiment of the present utility model in conjunction with the accompanying drawings.End flange headed by the left end of steel pipeline 8 in the accompanying drawing, right-hand member is terminal flange, its structure and measure-alike, unique difference is exactly not have suction tude 2 on the terminal flange.When needing pressure testing in the steel pipeline construction, just load onto the first and last end flange respectively at the head and end of every section natural pipeline section.Its erection sequence is that suction tude 2 and the pressure gauge 1 on the face-flange 3 can install in advance.At first loose flange 5 is enclosed within on the mouth of pipe, and firm with puller bolt 7 fixed installations.Seal ring 4 is packed in the circular groove of loose flange 5 again, and then load onto face-flange 3, and make its annular boss push down seal ring 4, with flange bolt 6 face-flange 3 being fixedlyed connected with loose flange 5 at last becomes one.Install, can send into pressurized air from suction tude 2 and carry out pressure test.If not pressure testing, only as temporary blocking, pressure gauge can be unloaded need not.
Claims (2)
1, a kind of interim shutoff flange of pipe end that is used for the steel pipeline construction, be divided into head end flange and terminal flange, it is characterized in that the head end flange is made up of pressure gauge, suction tude, face-flange, flange bolt, seal ring, loose flange and puller bolt, pressure gauge and suction tude all are installed on the face-flange, loose flange is fixedly mounted on pipe end by puller bolt, by flange bolt face-flange and loose flange are connected to a fixed one, terminal flange does not need suction tude, and all the other are identical with the head end flange.
2, the interim shutoff flange of pipe end according to claim 1 is characterized in that loose flange has a circular groove near the outside at tube wall place, and seal ring is housed in the groove, and face-flange is equipped with an annular boss in corresponding positions, can compress seal ring after installing.
