Abstract
The utility model provides a rapidly-disassembled fastening device which can quickly disconnect the connection of the pipe flange and the cover plate. The device is characterized in that the rapidly-disassembled fastening device adopts a couple of hinged semicircular clips with the groove at the inner circumferential face to fasten the connection of the pipe flange and the cover plate to achieve the fastening, sealing and pressure-proof purposes. A bolt is screwed or loosened to complete fastening and dismounting the connection of the pipe flange with the diameter smaller than 1 metre and the cover plate and achieve the rapidly-disassembled goal.
Description
The utility model relates to the locking device that a kind of pipeline connects, and particularly a kind of is in the pipeline of medium with liquid, the locking device that is connected of piping flange and cover plate.
In the crude oil production process, generally all at the front end of measuring instrument, former oil strainer is installed, with the service precision of measuring instrument in the protection pipeline road.Former oil strainer is the dismounting cover plate often, takes out filter core and cleans.12～20 of the many employings of the shell flange of at present common former oil strainer and the locking device of cover plate, many bolts of M20～M36, nut are connected, fastening, the connection locking device of this kind structure, Flange Plane is stressed irregular, compression resistance not, cause leakage easily,, waste time and energy as will often dismantling, labor intensity is big, downtime is long, and bolt corrosion easily kills, and the equipment that influences uses.
The purpose of this utility model is the locking device that will provide a kind of improved piping flange to be connected with cover plate, can overcome the shortcoming and defect of said structure, again can be efficient and convenient when fitting operation, new structure that performance is safe and reliable.
The utility model is realized as follows: replace traditional a plurality of bolts to lock being connected of crude oil filter cylinder flange and cover plate with two semicircle clamps.Two semicircle clamp 1,4 inner peripheral surfaces are fluted, the shape of this groove is consistent with the sectional shape that cover plate 5 is connected with filter cylinder flange 7 with size, and be that a trough rim less than 45 ° of inclined-planes is arranged equally, two semicircle clamps 1,4 end radially is hinged by bolt 8, bolt 8 is positioned on the bearing 10 on filter housings 11 outer walls, on the ear seat 3 of two semicircle clamps 1,4 the other end radially, hole, a garden is arranged respectively, be used for installing lock bolt 2.When screwing lock bolt 2, because the chamfered edge of the inclined-plane of two semicircle clamps, 1,4 further groove and cover plate 5 produces relative movement, it is tight more that cover plate 5 is pressed vertically more, thereby played the locking effect.When needing dismounting, take off lock bolt 2, two semicircle clamps 1,4 and divide right and left as long as unscrew and unload, cover plate 5 is promptly removable, filter core in the filter cleaner cylindrical shell can take out cleaning immediately, can repeat erection sequence after cleaning finishes, thereby reach the purpose of fast assembling-disassembling.This kind structure can be applicable to pipe diameter below 1 meter, manifold pressure is that the piping flange of medium connects with liquid in every square centimeter of scope below 250 kilograms.
The utility model is simple in structure, sealability is reliable, and is easy to operate, can finish installation, dismounting as long as twist a bolt, and can satisfy the oil field check man needs the job requirement of frequent quick detach fast-assembling oil purifier cover plate for cleaning filter core.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is that the schematic representation of form is adorned, torn open to the plan view and the reality of a kind of concrete structure of the present utility model;
Fig. 2 is the location schematic representation of a kind of concrete structure of the present utility model on cylindrical shell;
Fig. 3 is the sectional view of a kind of concrete structure of the present utility model.
Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3 according to the concrete device that the utility model proposes.
Fig. 1 is the fast assembling-disassembling locking device of a former oil strainer, adopt the Cast Steel of the ZG-25 trade mark to make two symmetrical semicircle clamps 1,4, respectively there are Xiao hole ear 9 and lock ear 3 in the radially two ends of each semicircle clamp, in the annulus of forming by two semicircle clamps 1,4, should reserve the 5-25 mm clearance radially connecting end face, the clamping force of two clamps when installing with assurance, two semicircle clamps 1,4 are hinged by the bolt 8 that is inserted in Xiao hole ear 9.The lock ear 3 of two semicircle clamps can be an axis with bolt 8, can separate or closed translation activity, when needs are closed and locked, need only bolt 2 is inserted in the lock earholes, screws to get final product.
Fig. 2 is the position structure of the hinge bolt 8 of this locking device, adopt the bearing 10 that the A20 steel is processed into to be fixed on the oil purifier cylindrical shell 11, hinge bolt 8 is fixed on position on the bearing 10 should satisfy the requirement that the axis of the axis of two semicircle clamps and filter cylindrical shell 11 coincides.
Fig. 3 is the sectional view of this locking device, oil purifier shell flange 7 contacts with the axial end of cover plate 5, cover plate 5 adopts No. 45 steel to make, and be processed into 30 ° of chamferings at the end face periphery, O type cushion rubber 6 is installed on shell flange, the sealing when being connected with cover plate 5 with assurance, the inner peripheral surface of two semicircle clamps 1,4 has a radial groove respectively, the shape of groove and cover plate 5 and shell flange 7 in conjunction with the time sectional shape consistent, but the groover rot diameter of clamp groove should be bigger 5～15 millimeters than cover plate 5 diameters.
When clamp is installed, put well put into O type rubber ring 6 on the oil purifier shell flange 7 of filter core after, promptly cover cover plate 5, then with about two semicircle clamps be close to axial direction simultaneously, bolt 2 is inserted in the two locking ears 3, screw bolt 2, because the inclined-plane of two halves garden clamp further groove and the hypotenuse of cover plate 5 produce the inclined-plane relative movement, make the periphery of cover plate 5 evenly stressed, along with the process that screws of bolt 2, cover plate 5 is pressed tight more vertically more, thereby has played the locking effect.
During dismounting, take off bolt 2, two semicircle clamps 1,4 and divide right and left as long as unscrew and unload, cover plate 5 is promptly removable, and the filter cores in the cylindrical shell 11 can take out cleaning immediately, and cleaning finishes can repeat erection sequence, thereby has reached the purpose of fast assembling-disassembling.
