Abstract
The utility model relates to a connection sealing member, which can be used for the connection of pipes in the refrigeration industry, the environment control industry, etc. and the sealing after perfusion cooling medium. The utility model comprises a pressing sleeve and a connection buckle which is buckled on the outer surface of a pipe end, and the pressing sleeve is tightly sheathed on the outer surface of the connection buckle. The both ends of the connection buckle are open and the middle part of the connection buckle is provided with a post table-shaped tenon segment, or one end is open and the other end is provided with a plug. The inner wall of the connection buckle is provided with at least one miniature bulge loop surface. With simple structure and convenient installation, the utility model has the advantages that the harm which is brought by refrigerant for people's health and safety because of weld is avoided, the labor intensity is reduced, the work efficiency is enhanced, and the larger tensile strength and strong sealing performance in the valid usage period can be ensured.
Description
The utility model relates to a kind of connection Sealing, sealing after can being widely used in the connection of pipe fittings such as refrigeration industry, environment control industry and pouring into refrigerant.
Along with the progress of society and the reinforcement of human environmental consciousness, traditional fluorinated refrigerant will be eliminated or be banned use of gradually, and new refrigerant will obtain application more and more widely.But exist unavoidable defective with above-mentioned two kinds of refrigeration agents respectively in the welded seal process that two-tube connection or pipe seal: fluorinated refrigerant (as R12, R22) can produce harmful matters such as phosgene, the physical and mental health that directly endangers people when welding temperature reaches 800 ℃; New refrigerant R134A, 209,401A, refrigeration agents such as 407C, 500,600A are flammable and explosive substance, in welding operation the personal safety meeting are threatened.In addition, welding procedure is loaded down with trivial details, inefficiency, labor intensity is big, sealing effect is unstable.
The purpose of this utility model is to provide a kind of quick extruding that need not welding procedure, sealing effect brilliance to connect sealing head at the defective of prior art.
Goal of the invention of the present utility model is achieved by the following scheme: this is extruding connection sealing head fast, comprise extruded sleeve and junction button, junction button is withheld the outer surface at pipe end, extruding is locked and is enclosed within the outer surface of junction button, the junction button both ends open, there are a pylon formula tenon section or an end opening in the centre, and the other end is shaped on plug.
Described junction button inwall can be shaped at least one miniature bulge loop face.
The utility model is simple in structure, easy to assembly, not only can avoid harm that the harmful matters such as phosgene that produce when welding temperature reaches 800 ℃ because of fluorinated refrigerant cause people's health and new refrigerant because of inflammable and explosive, the threat that in welding operation personal safety is caused; And can save the energy and silver-colored resource in the welding procedure, increase work efficiency, reduce labor intensity, can guarantee bigger tensile strength and very strong sealability in effective life, to sealing behind air-conditioning, the refrigerator perfusion refrigerant, and daily use maintenance brings great convenience.
Description of drawings:
Fig. 1 is the structural representation of the utility model tube-connecting type;
Fig. 2 is the A place enlarged view of Fig. 1;
Fig. 3 is the structural representation of the utility model pipe shutoff type.
Embodiment to the utility model is described further below in conjunction with accompanying drawing:
As Fig. 1, shown in Figure 3, the utility model is made up of two parts, an extruded sleeve 2 and a junction button 1.The Dimensions of extruded sleeve 2 and junction button 1 can be made according to connecting tube or by the different size of shutoff pipe and is connected.When two-tube connection sealed, junction button 1 was selected both ends open, and the centre is shaped on the both-end junction button of pylon formula tenon section 5, and when the single tube shutoff sealed, junction button 1 was selected an end opening for use, and the other end is shaped on the single-ended junction button of plug 7.
In order to reach the effect that better sealing and fastening are not pulled out, be shaped at least one miniature bulge loop face 6 at the inwall of junction button 1, generally be advisable with twice.During use, junction button 1 is withheld the outer surface at pipe end, and extruded sleeve 2 tightly is enclosed within the outer surface of junction button 1.Make connected tube 4 ports form a loudspeaker awl mouth by material extrusion-deformation, resilience, simultaneously, extruded sleeve is in extrusion process, junction button 1 is shunk, together with the miniature bulge loop face 6 of the twice of the junction button 1 inwall connected tube 4 (copper pipe, aluminum pipe or Bandaid pipe etc.) that links closely, form a rippled surface (as shown in Figure 2), reach the effect that fastening is not pulled out more.Withhold the junction button 1 that forms and material pressure in the connected tube 4 very big (tension pressure can reach 68Kgf/cm according to above
2More than, the moment resistance to compression can reach 360Kgf/cm
2), thereby can form one deck mating face and two seals clasp closely, sealing effect is quite superior.If add quick squeezed joint sealing compound 3, the defective such as trace of drawing of microcosmic is remedied, shutoff is leaked and is passed through comprehensively, and its air-tightness is remarkable more.
Claims (2)
1. one kind is pushed the connection sealing head fast, comprise extruded sleeve (2) and junction button (1), it is characterized in that described junction button (1) withholds the outer surface at pipe end, extruded sleeve (2) tightly is enclosed within the outer surface of junction button (1), junction button (1) both ends open, there are a pylon formula tenon section (5) or an end opening in the centre, and the other end is shaped on plug (7).
2. quick extruding as claimed in claim 1 connects sealing head, and it is characterized in that: described junction button inwall has a miniature bulge loop face (6) at least.
