Ferrule air inlet system disclosed in the utility model, be mainly used in the process of products air tightness detection, such as commercial water purifier is after the sweat soldering completing base plate part, with regard to needing, the welding airtightness of inside is tested, this ferrule air inlet system comprises air inlet plug 1, seal ring 3, port sealing piece 4 and compressing member, wherein the end of air inlet plug 1 is provided with the inserting section 2 of detecting tube 11 inside can inserting product, as shown in fig. 1, and the suction port 7 air inlet plug 1 is also provided with usually for being connected with pneumatic tube, seal ring 3 is set on the outer wall of inserting section 2, and after inserting section 2 extend into detecting tube 11 inside, seal ring 3 can realize being sealed and matched between detecting tube 11 inwall.Port sealing piece 4 is fixedly installed on air inlet plug 1, port sealing piece 4 is after inserting section 2 extend into detecting tube 11 inside simultaneously, press seal can also be realized with the mouth of pipe of detecting tube 11, as shown in Figures 2 and 3, compressing member is mainly used in mouth of pipe position port sealing piece 4 being pressed on detecting tube 11, to ensure the sealability at detecting tube 11 mouth of pipe position.
Be not difficult to find, in ferrule air inlet system disclosed in above-described embodiment, double sealing structure is defined between air inlet plug 1 and detecting tube 11, wherein seal ring 3 constitutes with the inwall of detecting tube 11 and prevents the first of Leakage Gas from sealing, compressing between the mouth of pipe of detecting tube 11 and port sealing piece 4 to define prevents the second of Leakage Gas from sealing, compared to the single track sealing means between current air inlet plug 1 and detecting tube 11, add second at the mouth of pipe place of detecting tube 11 in Placement between air inlet plug 1 disclosed in the utility model and detecting tube 11 to seal, even if having Leakage Gas between the inwall of seal ring 3 and detecting tube 11, so second sealing also effectively can prevent the gas from leaking to outside, thus this just effectively improves the sealability between air inlet plug 1 and detecting tube 11, and then ensure that the reliability of air-leakage test result.
As shown in Figure 2, under normal circumstances, in order to make the structure of ferrule air inlet system compacter, those skilled in the art also can arrange a support device for support compression part, and in the present embodiment, compressing member is specially piston cylinder 8, certain piston cylinder 8 can be cylinder or oil cylinder, and the cylinder body of piston cylinder 8 and compressing member fixed plate 9 are fixedly linked, the pistons end of piston cylinder 8 is fixedly connected with mobile plate 10, and air inlet plug 1 is fixedly connected on mobile plate 10.
Compressing member fixed plate 9 is fixed block, itself position is constant, thus in the flexible process of the piston rod of piston cylinder 8, drive mobile plate 10 seesaws by piston rod, mobile plate 10 drives the air inlet plug 1 be connected with it to seesaw, and then makes the port sealing piece 4 be fixedly installed on air inlet plug 1 realize press seal with the mouth of pipe of detecting tube 11.
It is easily understood that, the mechanism that compressing member can also adopt other can realize seesawing except adopting piston cylinder replaces, the screw slider mechanism such as, provided in the present embodiment, concrete, leading screw carries out clockwise and counterclockwise rotation by driven by motor, slide block coordinates with leading screw, and the circumference of slide block is fixed, thus under the effect of screw turns, slide block only can move along the axial direction of leading screw, air inlet plug 1 is fixedly connected on slide block, thus under the drive of slide block, air inlet plug 1 can realize seesawing, air inlet plug 1 drives the port sealing piece 4 be connected with it to realize press seal with the mouth of pipe of detecting tube 11.
Disclose the way of realization of two kinds of concrete compressing members in above-described embodiment, should be appreciated that except above-mentioned two kinds of ways of realization, compressing member also has multiple different way of realization, introduces no longer one by one in the utility model embodiment to this.
In order to ensure sealing effect further, in the present embodiment, the quantity of seal ring 3 sheathed on inserting section 2 outer wall should be no less than two, as shown in fig. 1, more preferred, the outer wall of inserting section 2 offers the seal ring receiving groove for holding seal ring 3, and the quantity of seal ring receiving groove is consistent with the quantity of seal ring 3 in inserting section 2, and seal ring receiving groove can effectively prevent seal ring 3 at the axially play of inserting section 2.
The side that port sealing piece 4 is relative with detecting tube 11 can be plane structure, after port sealing piece 4 contacts with detecting tube 11, there is deformation in port sealing piece 4, thus the mouth of pipe of detecting tube 11 is encircled sealing, in order to improve the sealing effect of detecting tube 11 port further, the side that the present embodiment middle port Sealing 4 is relative with detecting tube 11 also offers the closure gasket groove that can embed for the end of detecting tube 11, and the groove width of closure gasket groove should be slightly less than the thickness of detecting tube 11 tube wall, difference is preferably at 0.3-0.5mm, so that closure gasket groove can be formed the mouth of pipe of detecting tube 11 encircle sealing closely.The inner side surface of closure gasket groove also can be provided with guiding surface, to facilitate in the smooth embedding sealing annular groove in the end of detecting tube 11, the usual tapered inclined-plane of guiding surface.
As shown in fig. 1, be conveniently inserted into the inside of detecting tube 11, the end of air inlet plug 1 inserting section 2 is also provided with taper guiding surface 6, and the tapering of taper guiding surface 6 is between 20 °-30 °.
Port sealing piece 4 can directly be fixed on air inlet plug 1, but in order to ensure that port sealing piece 4 itself has enough support strengths, port sealing piece 4 needs to have larger thickness, in for this reason disclosed in the present embodiment ferrule air inlet system, air inlet plug 1 also has location shoulder 5, location shoulder 5 can also can be detachable structure for integral type structure with air inlet plug 1, and port sealing piece 4 is fixedly installed on the shoulder 5 of location, as shown in fig. 1.
In the utility model embodiment, the rubber seal that seal ring 3 is preferably soft, the rubber port sealing piece that port sealing piece 4 is preferably soft, so that the reliable sealing utilizing seal ring 3 and the larger plastic deformation ability of port sealing piece 4 itself to realize between air inlet plug 1 and detecting tube 11.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
