At present, the detachable air conditioner indoor side of common working medium uses pipe joint to be connected vaporizer and connecting tube with the mode of union nut mostly, can produce the coolant leakage problem dismantled by mistake and cause.
In prior art, there is the technological scheme directly adopting indoor side vaporizer and connecting tube welding, outdoor to adopt rapid pipe joint, though the requirement of standard and Security can be met, but still there is Railway Project: one, rapid connector component cost is higher, directly causes air-conditioning cost high; Its two, install after sale and be subject to the restriction of connecting tube, product using scope reduces further.
Summary of the invention
The utility model mainly provides a kind of Anti-detachable pipe connector assembly and air conditioner thereof, and the adapter realizing Anti-dismantling connects, and reduces I&M cost after sale, expands the Applicable scope of combustible refrigerant; Easy installation, structure is simple, easy to process.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: Anti-detachable pipe connector assembly of the present utility model comprises pipe joint body, union nut and pushnut, described union nut and pushnut are threaded with described pipe joint body two ends respectively, are provided with self-locking packing ring between described union nut and described pipe joint body.
As preferably, described pipe joint body two ends are shaped with the first thread section and the second thread section, and described first thread section is connected with described union nut, and described second thread section is connected with described pushnut, are shaped with outstanding boss in the middle part of described pipe joint body.
As preferably, the termination with tapering chamfering is arranged in the termination, one end that described pipe joint body is connected with described union nut, between described first thread section of described pipe joint body and described boss, position is self-locking packing ring installation position, and described self-locking packing ring installation position is without thread section.
As preferably, described pipe joint body is hollow tube structure.
As preferably, described self-locking packing ring is ring-type, and described self-locking packing ring is provided with a fracture.
As preferably, described self-locking packing ring is spring washer or saucer washer or flank of tooth lock washer or two-fold self-locking packing ring or saddle type pitted skin packing ring.
As preferably, the tapering joint of described union nut for matching with the termination with tapering chamfering described in described pipe joint body.
As preferably, the tooth pitch of described first thread section is less than the second thread section tooth pitch.
A kind of air conditioner of the present utility model, comprises above-mentioned Anti-detachable pipe connector assembly.
The beneficial effect that the utility model brings is, the utility model is by increasing self-locking packing ring, improve the secondary refrigerant leakage problem caused after being disassembled between existing pipe joint and union nut connection, the adapter realizing Anti-dismantling connects, and reduce I&M cost after sale, expand the Applicable scope of combustible refrigerant; Easy installation, structure is simple, easy to process.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of inside configuration schematic diagram of the present utility model;
Accompanying drawing 3 is a kind of stereo decomposing structural representations of the present utility model.
Label declaration: 1, union nut; 2, self-locking packing ring; 2-1, fracture; 3, pushnut; 4, pipe joint body; 4-1, boss; 4-2, the first thread section; 4-3 second thread section; 4-4, self-locking packing ring installation position.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the Anti-detachable pipe connector assembly of the present embodiment and air conditioner thereof are as shown in Figure 1, 2, 3, comprise pipe joint body 4, union nut 1(and copper and receive son) and pushnut 3, union nut 1 and pushnut 3 are threaded with pipe joint body 4 two ends respectively, are provided with self-locking packing ring 2 between union nut 1 and pipe joint body 4.
Pipe joint body 4 two ends are shaped with the first thread section 4-2 and the second thread section 4-3, and the first thread section 4-2 is connected with union nut 1, and the second thread section 4-3 is connected with pushnut 3, are shaped with outstanding boss 4-1 in the middle part of pipe joint body 4.
The tooth pitch of the first thread section 4-2 is less than the second thread section 4-3 tooth pitch.The coupling mechanism force of such union nut 1 and pipe joint body 4 is greater than the coupling mechanism force between pushnut 3 and pipe joint body 4, coordinate self-locking packing ring 2 again, when loosening pushnut 3 with spanner, the still motionless ground of union nut 1 be connected on pipe joint body 4, formed between union nut 1 and pipe joint body 4 and non-disconnectablely tear structure open.
The termination with tapering chamfering is arranged in the termination, one end that pipe joint body 4 is connected with union nut 1, and between the first thread section 4-2 of pipe joint body 4 and boss 4-1, position is self-locking packing ring 2 installation position, and self-locking packing ring installation position 4-4 is without thread section.
Pipe joint body 4 is hollow tube structure.
Self-locking packing ring 2 is ring-type, self-locking packing ring 2 is provided with a fracture 2-1.Self-locking packing ring 2 can select spring washer or saucer washer or SKS type flank of tooth lock washer or the two-fold self-locking packing ring 2 of stainless steel-DIN25201 or VSK saddle type pitted skin packing ring.
Union nut 1 is the tapering joint matched with the termination of tapering chamfering with pipe joint body 4.
A kind of air conditioner of the present embodiment, comprises the Anti-detachable pipe connector assembly of the present embodiment.
Pushnut 3 connecting pipe joint body 4 one end under working state, when applying clockwise moment at pushnut 3, independently pipe joint body 4 and pushnut 3 two part energy synchronous rotaries, after the two enters into locking position, the two is integrated coupling mechanism force continuation transmission, guarantee that pipe joint body 4 and union nut 1 are threaded connection, self-locking packing ring 2 adds the coupling mechanism force between pipe joint body 4 and union nut 1, when applying anticlockwise moment to pushnut 3, due to the effect of self-locking packing ring 2, the self-lock force between union nut 1 and pipe joint body 4 is made to be greater than self-lock force between pushnut 3 and tapering joint, moment of torsion only makes pushnut 3 be separated with tapering joint, thus ensure that closely cooperating between union nut 1 and pipe joint body 4, serve Anti-dismantling effect, also avoid abnormal sound when vibrating.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is restriction to the utility model protection domain.The utility model is not only confined to above embodiment, and its concrete structure or shape allow to change.In a word, protection domain of the present utility model should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
