Description
Technical field
The present invention relates to air-tightness leak detection field, especially a kind of sealing for special bend pipe air tightness of hunting leak of part
Device.
Background technology
In daily life, pressure pipeline is closely bound up with us, and the leakage situation of these parts directly influences me
Production and life, therefore the part of certain operating pressure is born for these, need to enter promoting the circulation of qi to it after completion of processing
Close property leak detection, and the key link hunted leak is then sealing.Seal failure is frequently not the insufficient strength because connector, most feelings
Because sealing not in place and causing leakage under condition, for the general bend pipe mouth of pipe, first mouth of pipe 6 in Fig. 5 is can refer to
Shown in, the sealing means of use are strong side seals, i.e., the place that can be compressed can be machined with bend pipe mouth, can be by system
Make special sealing plate, using sealing ring or gasket seal, then fastened by installation bolt, this is according to sealing ring or close
The fine gap of sealing surface is filled up to stopper and reaches sealing purpose by the plasticity of gasket, realizes No leakage.But for special
The bend pipe mouth of pipe, as shown in second mouth of pipe 7 in Fig. 5, not processed according to the requirement for using unnecessary can make sealing
The place that plate is compressed, for this special bend pipe during air-tightness leak detection, general method is not applied to simultaneously to this.
The content of the invention
The technical problems to be solved by the invention are：Brought to air-tightness leak detection to overcome special bend pipe to be difficult to seal
A kind of difficult deficiency, there is provided sealing device for special bend pipe air tightness of hunting leak, it is intended to solve above-mentioned pin in the prior art
The problem hunted leak to special bend pipe air tightness and existed.
The technical solution adopted for the present invention to solve the technical problems is：It is a kind of for the close of special bend pipe air tightness of hunting leak
Seal apparatus, including sealing plate, U-shaped circle and some plates, the first groove walls are brought into close contact in the outer ring of the U-shaped circle and bend pipe,
The sealing plate is inserted into U-shaped circle, and the outer ring of sealing plate is brought into close contact with the inner ring of U-shaped circle, sealing plate side bottom circumference
The dome of annular is provided with, the upper surface of the dome is brought into close contact with the lower surface of U-shaped circle, the lower surface edge of the sealing plate
Circumferential uniformly to connect some plates, the outside facial contour of the plate is consistent with the second groove walls profile in bend pipe.
In order that the position of plate is adjustable, waist type groove is offered on the plate, the sealing plate lower surface is circumferentially
The screwed hole corresponding with waist type groove uniformly is offered, the sealing plate and plate are by the bolt through kidney slot and screwed hole
It is fixedly connected.
The beneficial effects of the invention are as follows：A kind of sealing device for special bend pipe air tightness of hunting leak of the invention, realizes
Lack the sealing of the local special bend pipe for compressing sealing plate at the mouth of pipe, so as to reach the purpose of air-tightness leak detection；Use
When, sealing plate is put into bend pipe hole, the position of plate is adjusted, its lateral surface is fitted with the second groove walls, another side pressure
Tight backward inner chamber ventilation, under pressure work, sealing plate and U-shaped circle is compressed, so as to play sealing function, apparatus structure letter
It is single, it is practical and convenient.

Specific embodiment
Presently in connection with accompanying drawing, the present invention is described in detail.This figure is simplified schematic diagram, is only illustrated in a schematic way
Basic structure of the invention, therefore it only shows the composition relevant with the present invention.
Sectional view as shown in Figure 2, a kind of sealing device for special bend pipe air tightness of hunting leak, including sealing plate 1, U
Type circle 2 and some plates 3, first groove walls 41 are brought into close contact in the outer ring of the U-shaped circle 2 and bend pipe 4, and the sealing plate 1 is inserted
In U-shaped circle 2, the outer ring of sealing plate 1 is brought into close contact with the inner ring of U-shaped circle 2, and the side bottom of sealing plate 1 is circumferentially provided with ring
The dome 11 of shape, the upper surface of the dome 11 is brought into close contact with the lower surface of U-shaped circle 2, and the lower surface of the sealing plate 1 is along week
To some plates 3 are uniformly connected, the outside facial contour of the plate 3 is consistent with the profile of the second groove walls 42 in bend pipe 4.
As shown in Figure 3 and Figure 4, in order that the position of plate 3 is adjustable, waist type groove 31 is offered on the plate 3, it is described
The lower surface of sealing plate 1 is evenly distributed and offers the screwed hole 12 corresponding with waist type groove 31, and the sealing plate 1 and plate 3 are logical
Cross and be fixedly connected with the bolt 5 of screwed hole 12 through kidney slot 31.
Special bend pipe 4 as shown in Figure 5 is adjacent from top to bottom on the inwall of second mouth of pipe 7 to offer the institute of the first groove walls 41
Annular low groove corresponding to corresponding annular upper groove and the second groove walls 42, the upper groove and low groove are communicated,
And upper groove diameter is less than low groove diameter.
Operation principle of the invention is illustrated with reference to Fig. 1-4：When using, plate 3 is connected on sealing plate 1 to be made at it
In free state, it is put into after turning down in second mouth of pipe 7, then adjusts the position of plate 3, makes the lateral surface of plate 3 recessed with second
Cell wall 42 fits, and it is stuck in groove, fastening bolt 5, and the other end of bend pipe compresses the backward inner chamber of bend pipe 4 inflation, now,
Pressure, pressure will be produced the upper surface of sealing plate 1 and U-shaped circle 2 is acted in tube chamber, therefore be fixedly connected with sealing plate 1
The lower surface of plate 3 mutually extrudes with the corresponding groove of the second groove walls 42 in bend pipe 4, and because U-shaped circle 2 has plasticity, therefore U
Fine gap between the outer ring of type circle 2 and the first groove walls 41 and between the U-shaped inner ring for enclosing 2 and the side of sealing plate 1 will
Can be filled and stopper, and intraluminal gas pressure is bigger, the plastic deformation of U-shaped circle 2 is bigger, and the extruding force of generation is bigger, from
And realize sealing effectiveness.
A kind of sealing device for special bend pipe air tightness of hunting leak of ingehious design of the present invention, is compared to general curved
For pipe, the purpose of self-locking seal can not be being realized by force in the case of side seal, i.e., as overpressure is increased same
When, sealing effectiveness is also improved, and the apparatus structure is simple, practical and convenient.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, related staff
Various changes and amendments can be carried out in without departing from the scope of the present invention completely.The technical scope of this invention is not
It is confined to the content on specification, it is necessary to its technical scope is determined according to right.
