The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Such as Fig. 1, the utility model proposes a kind of closeouts for hot-water heating PPR pipe, including inner sleeve 3, stretch into PPR pipe 1 One end be equipped with several fixed jaws 301, inner seal ring 6 is embedded on outer circle side wall;Sealing bolt 5, shaft 502 Stretch into inner sleeve 3 and therewith thread connection when, the end of shaft 502 makes fixed jaw 301 discrete;The nut of sealing bolt 5 Part 501 and inner sleeve 3 are equipped with exterior seal ring 4 between being placed in the end outside PPR pipes 1.
Inner sleeve 3 and PPR pipe 1 for transition it is mating (the outer circle side wall of inner sleeve 3 is bonded with the inner circle side wall of PPR pipe 1, two Gap between person is smaller).
The outside of above-mentioned inner sleeve 3 is additionally provided with housing 2, and housing 2 is fixed in inner sleeve 3 close to above-mentioned nut by terminal pad 201 One end of part 501.As shown in Figure 1, 2, housing 2 is sheathed on the outside of inner sleeve 3, and left end and terminal pad 201 are affixed, inner sleeve 3 Left end it is also affixed with terminal pad 201, be integrally formed.
Such as Fig. 2,3, several spin-ended teeth 202 are equipped with around its axis on the madial wall of above-mentioned housing 2.Above-mentioned spin-ended tooth 202 Sharp edge along the axially extending of above-mentioned housing 2.When tool is used to clamp housing 2, the Sharp edge pressure of spin-ended tooth 202 The outer circle side wall of tight PPR pipe 1, avoids relatively rotating between inner sleeve 3 and PPR pipe 1, ensures that fixed jaw 301 can consolidate card Tight PPR pipe 1.
The rotation direction of the extending direction and housing 2 of the Sharp edge of above-mentioned spin-ended tooth 202 is perpendicular, which increases spin-ended Resistance during relative motion occurs between tooth 202 and PPR pipe 1.
Above-mentioned fixed jaw 301 is evenly distributed with around the axis of above-mentioned inner sleeve 3, and the free end of fixed jaw 301 is to the axis of inner sleeve 3 Gather;The side wall of fixed jaw 301 towards above-mentioned housing 2 is equipped with the sharp block 302 of clamping.The Sharp edge of above-mentioned clamping point block 302 Along the tangentially extending of above-mentioned inner sleeve 3.After the tail portion of sealing bolt 5 is contacted with fixed jaw 301, the knot gathered to 3 axis of inner sleeve Structure can make the amount of movement increase of fixed jaw 301 in inner sleeve 3 radially, help to force between the sharp block 302 of clamping and PPR pipe 1 Clamping fixed.The Sharp edge of the sharp block 302 of the clamping tangentially extending along inner sleeve 3 can avoid inner sleeve 3 from being skidded off out of PPR pipe 1.
The extending direction and the plugging direction of inner sleeve 3 of the Sharp edge of above-mentioned clamping point block 302 are perpendicular, structure increase Resistance during relative motion occurs between inner sleeve 3 and PPR pipe 1.
The tail end of above-mentioned shaft 502 pushes away platform 503 equipped with co-axial;It is affixed with shaft 502 to push away platform 503 One end is relatively large in diameter, and other end diameter is smaller, and is seamlessly transitted between both ends.By push away platform 503 can sealing bolt 5 with it is interior During set 3 is tightened, fixed jaw 301 is gradually oppressed outward.
Such as Fig. 1, above-mentioned exterior seal ring 4 is flush-mounted in above-mentioned nut portion 501 close to one end of above-mentioned terminal pad 201, and stretches Go out nut portion 501;Terminal pad 201 is equipped with exterior seal ring 4 to corresponding closure gasket groove 203.When tightening sealing bolt 5, The exterior seal ring 4 for stretching out nut portion 501 is extend into closure gasket groove 203, and is deformed upon by the extruding of closure gasket groove 203, from And reach sealing effect.
The outer profile of 501 longitudinal section of above-mentioned 2 longitudinal section of housing and above-mentioned nut portion is regular hexagon.The structure is convenient Housing 2 is clamped and rotatory sealing bolt 5, it is easy to disassemble.
In use, first inner sleeve 3 is inserted into PPR pipe 1, the end and terminal pad 201 for making PPR pipe 1 offset.Using work Tool clamping housing 2 compresses the lateral wall of PPR pipe 1 by spin-ended tooth 202, prevents that opposite turn occurs between PPR pipe 1 and inner sleeve 3 It is dynamic.Sealing bolt 5 is inserted into the threaded hole at 3 middle part of inner sleeve, rotatory sealing bolt 5 (such as Fig. 2).In screwing hermetic bolt 5 During, it pushes away platform 503 and gradually oppresses fixed jaw 301 outward, make the madial wall clamping fixed of clamping point block 302 and PPR pipe 1. Meanwhile also compressive deformation, realization seal inner seal ring 6 in this process.In addition, exterior seal ring 4 squeezes hair by closure gasket groove 203 Change shape, realizes sealing.
In the utility model, it is sealed between inner sleeve 3 and PPR pipe 1 by the inner seal ring of compressive deformation 6.Inner sleeve 3 with It is sealed between sealing bolt 5 by the exterior seal ring 4 of connection screw thread and compressive deformation.
Closeouts described in the utility model for hot-water heating PPR pipe, convenient for disassembly and assembly, good airproof performance.Pass through general tool Rotatory sealing bolt 5, you can complete the fractionation between the utility model and PPR pipe 1 and connection work.Pass through inner sleeve 3 and stud The connection screw thread of the mutual cooperation of part 502 forms first of threaded sealing structure;Pass through 4 He of exterior seal ring of compressive deformation Closure gasket groove 203 forms the second seal structures, and two sealed structures can ensure the leakproofness of the utility model, avoid PPR Water in pipe 1 leaks between inner sleeve 3 and sealing bolt 5.Simultaneously as exterior seal ring 4 is not in direct contact with PPR pipe 1, it can Slow down aging, improve its service life.It in addition, can will be between PPR pipe 1 and inner sleeve 3 by the inner seal ring 6 of compressive deformation Gap blocks completely.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
