Description

A kind of multipurpose lost circulation plug
Technical field
The utility model relates to blockage structure fields, and in particular to a kind of multipurpose lost circulation plug.
Background technique
In electric power factory equipment operation, operating on low voltage medium pipeline is frequently encountered, container corrosion is thinned, perforation causes outside working medium The case where letting out.System can not it is completely isolated or stop transport maintenance in the case where, for block container leakage point, prevent defect from expanding, Staff passes through frequently with stopper and carries out interim leak stopping processing.
Traditional detection method needs this method, and there are many deficiencies: one, stopper generally requires temporarily to make, material searching, Time-consuming for cutting production, is unable to satisfy rush repair time requirement;Two, stopper generally uses taper or rotary table shape, interior small outer Greatly, easily deviate from when pressure is higher, be not suitable with long-play requirement;Three, the elasticity of stopper is smaller, and expansion decrement is insufficient, When leakage point is in irregular shape, it can not be filled up completely leakage position, processing is caused to be not thorough.
Utility model content
In view of this, the purpose of the utility model is to provide a kind of multipurpose lost circulation plug, it can be achieved that low pressure vessel pipeline Effective leak stopping processing of leakage, to guarantee that equipment safety is run steadily in the long term.
The utility model is solved the above problems by following technological means: a kind of multipurpose lost circulation plug, including expander and Pull rod, the expander include the outer expanding block and interior expanding block of socket, and the outer expanding block and interior expanding block are round table-like And be made of elastic material, described pull rod one end is provided with pressing plate, and the other end is provided with square spigot, and pull rod passes through cone and pressure Plate connection, the expander side are contacted with pressing plate, and the other side has overlapped washer and nut, and the pull rod sequentially passes through swollen Swollen body, washer and nut, pull rod are connect with nut thread.
Further, the pressing plate and expander contact side side are provided with the cyclic annular indent with expander clamping.
Further, the pressing plate is contacted with outer expanding block, and the washer is contacted with interior expanding block.
Further, the pressing plate is contacted with interior expanding block, and the washer is contacted with outer expanding block.
Further, the pressing plate and pull rod are integrally formed, and the square spigot is also integrally formed with pull rod.
The utility model has the beneficial effects that the multipurpose lost circulation plug of the structure, including expander and pull rod, the expander Outer expanding block and interior expanding block including socket, the outer expanding block and interior expanding block are round table-like and by elastic material system At described pull rod one end is provided with pressing plate, and the other end is provided with square spigot, and pull rod is connect by cone with pressing plate, the expansion Body side is contacted with pressing plate, and the other side has overlapped washer and nut, and the pull rod sequentially passes through expander, washer and spiral shell Mother, pull rod are connect with nut thread.The lost circulation plug of the structure, it can be achieved that effective leak stopping to low pressure vessel pipe leakage is handled, It ensure that equipment safety is run steadily in the long term, there is good economic benefit.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural schematic diagram of the utility model;
Fig. 2 is another structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below with reference to attached drawing, as shown in Figs. 1-2: the multipurpose of the utility model Lost circulation plug, including expander, pull rod 1, washer 4 and nut 5, the expander include the outer expanding block 2 and interior expanding block of socket 3, the outer expanding block and interior expanding block are round table-like and are made of elastic material, and described pull rod one end is integrally formed with pressure Plate, the other end are connect by cone with pressing plate integrally formed with square spigot 6, pull rod, and pull rod, cone, pressing plate are integrally formed, expansion Body is between pressing plate and washer, and there are two types of specific assembling forms: a kind of as shown in Figure 1, outer expanding block and interior expanding block It is arrangement form of the miner diameter end in upper, bigger diameter end under, is contacted at the top of pressing plate and outer expanding block, washer and interior expanding block Bottom contact;As shown in Fig. 2, the handstand of interior expanding block is arranged at the top of outer expanding block, pressing plate contacts another kind with interior expanding block, pads Circle is contacted with outer expanding block.The pull rod sequentially passes through expander, washer and nut, and pull rod is connect with nut thread.To improve The stability that pressing plate is contacted with expander is provided with and presses with the cyclic annular of expander clamping in pressing plate and expander contact side side Slot.
Working principle:
In use, expander is inserted into leak, with matched square spigot spanner or manual wrench and firmly drawing after holding out against The square spigot of bar end, rotating nut, under the cooperation of pull rod and nut, nut axial movement, extrusion expansion body, due to pull rod One end is connect by cone with pressing plate.Under the effect of inside and outside expanding block, the entire outer diameter of expander becomes larger tensioner, thus It is entirely capable of that hole plug will be leaked.The elastic expansion of expander can effectively block the irregularity of leak, can effectively prevent Only lost circulation plug falls off from leakage place when in use.The utility model can be made into different sizes, seriation be formed, directly with spanner etc. It is operated, it is easy to use.Using the elasticity of expander, the leak of various situations can be suitable for, completely plugged can be let out Leak hole.The utility model is simple in construction, easy to disassemble and assemble, be suitable for system can not it is completely isolated or stop transport maintenance in the case where, block up Container leakage point is filled in, prevents defect expansion etc. to be badly in need of using in the case where leak stopping, performance is stablized, and wanting for long-time leak stopping is able to satisfy It asks.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
