Description
Technical field
The utility model belongs to metal catheter air tightness test technical field, particularly the universal conduit seal plug of one.
Background technique
At present, in industrial field, a lot of system equipment all can be applied to metal catheter, and requires very high to the tightness of these metal catheters, therefore all can carry out air tightness test to its metal catheter.But all must seal conduit when carrying out metal catheter air tightness test, blocking, is all adopt plug to seal conduit, block now usually.
Model utility content
Existing plug is all the fixing cock body of a simple specification, the conduit of different size (diameter) cannot be common at all, but each system equipment is generally the conduit applying multiple different size, therefore need to customize corresponding plug according to the joint of different size conduit, even the conduit of same diameter, need due to the difference of joint form, the diameter of thread, pitch to customize different plugs.Such as: the metal catheter that aircraft have employed 5 kinds of different-diameters, have employed again pipe joint forms different in 4 simultaneously, according to permutation and combination, need the plug of customization 20 kinds of specifications, just can complete the air tightness test of all conduits.Like this, cause fund waste and resources idle, simultaneously because plug kind is too many, management and is also inconvenient.
For solving the above-mentioned technical problem existed in prior art, it is extremely strong that the utility model provides a kind of versatility, effectively economizes on the use of funds, install fast, simple and convenient management, structure is simple, fabricating cost is cheap, and it is flexible, convenient to use, the universal conduit seal plug that plug for seal is effective, secure.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of universal conduit seal plug, includes elastic expansion sealing drum, strain pin and standby jack panel; Described elastic expansion sealing drum is cylindrical body, and it is provided with the pin-and-hole being communicated with two ends; One end of described strain pin is provided with oblate pressure card division, and the other end is provided with the screw section matched with standby jack panel; During use, described strain pin is removably located in pin-and-hole, and described oblateness pressure card division is stuck in pin-and-hole and compress the front end surface of elastic expansion sealing drum outward, described screw section is stretched out from the rear end of elastic expansion sealing drum, described standby jack panel to be screwed on screw section and to compress the rear end end face of elastic expansion sealing drum, makes that the circumferential cylinder of elastic expansion sealing drum outwards expands, sealing duct.
Further, described elastic expansion sealing drum is rubber seal cylinder.
Further, described elastic expansion sealing drum is the large trapezoidal cylindrical body in little rear end, front end.
Further, described pin-and-hole and elastic expansion sealing drum are same axle core.
Further, described strain pin, oblate pressure card division and screw section adopt stainless steel material one-body molded.
The beneficial effects of the utility model are:
The utility model passes through technique scheme, namely block, seal the conduit of different size with the outside expansion amplitude of circumferential cylinder controlling elastic expansion sealing drum by the pressure of adjustable elastic Expansion sealing cylinder rear and front end, versatility is extremely strong, quantity and the specification of traditional plug can be greatly reduced, effectively economize on the use of funds, install fast, simple and convenient management, and structure is simple, fabricating cost is cheap; In addition also can according to the difference of the force value of pressurising in conduit, the frictional force between elastic expansion sealing drum and duct wall is increased by the pressure of adjustable elastic Expansion sealing cylinder rear and front end, overcome the thrust that air pressure is applied to plug end face, it is flexible, convenient to use, and plug for seal is effective, secure.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of universal conduit seal plug embodiment described in the utility model;
Fig. 2 is the structural representation of a kind of universal conduit seal plug embodiment Elastic Expansion sealing cylinder described in the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figures 1 and 2:
The universal conduit seal plug of one described in the utility model embodiment, includes elastic expansion sealing drum 1, strain pin 2 and standby jack panel 3.Described elastic expansion sealing drum 1 can be rubber seal cylinder, is cylindrical body, and it is provided with the pin-and-hole 11 being communicated with two ends, and described pin-and-hole 11 is same axle core with elastic expansion sealing drum 1; One end of described strain pin 2 is provided with oblate pressure card division 21, and the other end is provided with the screw section 22 matched with standby jack panel 3, and described strain pin 2, oblate pressure card division 21 and screw section 22 adopt stainless steel material one-body molded.
When universal conduit seal plug described in the utility model uses, first strain pin 2 is removably located in pin-and-hole 11, and to be stuck in pin-and-hole 11 outer and compress the front end surface of elastic expansion sealing drum 1 in oblate pressure card division 21, screw section 22 is stretched out from the rear end of elastic expansion sealing drum 1, and standby jack panel 3 is screwed on screw section 22; Then seal plug (front end of elastic expansion sealing drum 1) is filled in conduit 4; Finally tighten standby jack panel 3, allow oblate pressure card division 21 and standby jack panel 3 compress front end surface and the rear end end face of elastic expansion sealing drum 1 simultaneously, elastic expansion sealing drum 1 is outwards expanded because of stressed thus its circumferential cylinder in rear and front end, slowly fit tightly with duct wall, thus play the effect of blocking, sealing duct 4.
Like this, seal plug described in the utility model is namely by turning standby jack panel 3 to regulate the rear and front end applied pressure of oblate pressure card division 21 and standby jack panel 3 pairs of elastic expansion sealing drums 1, thus the outside expansion amplitude of circumferential cylinder controlling elastic expansion sealing drum 1 blocks, seals the conduit of different size, versatility is extremely strong, quantity and the specification of traditional plug can be greatly reduced, effectively economize on the use of funds, use mounting type to break away from traditional airtight plug to the strict demand of jointing form simultaneously, install quicker, manage easier; And structure is simple, fabricating cost is cheap; In addition also can according to the difference of the force value of pressurising in conduit, by turning standby jack panel 3 to regulate oblate pressure card division 21 and to increase the frictional force between elastic expansion sealing drum 1 and duct wall for the rear and front end applied pressure of jack panel 3 pairs of elastic expansion sealing drums 1, overcome the thrust that air pressure is applied to plug end face, it is flexible, convenient to use, and plug for seal is effective, secure.
In addition, described elastic expansion sealing drum 1 is the large trapezoidal cylindrical body in little rear end, front end; Can be installed in conduit more convenient, rapidly during such use.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
