Abstract
The utility model relates to a special quick connector for preventing water leakage of a household RO (Reverse Osmosis) water purifier. The special quick connector comprises a body, a sealing ring, a cover nut, a toggle clip and a clamp clip; the body is a cylinder body internally provided with a cavity; one end of the body is provided with a step-shaped through hole; a fixing insertion hole in which an external pipe is inserted is formed in the bottom of the step-shaped through hole; the diameter of the fixing insertion hole is smaller than the diameter of the cavity, so as to form a step; the sealing ring is placed on the step; the cover nut, the toggle clip and the clamp clip are sequentially arranged inside the step-shaped through hole according to requests; and a fixing structure through which a pipe can pass is additionally arranged at the upper end of the sealing ring. When the quick connector is in use, the pipe inside the body of the quick connector is firmly fixed and held through the fixing structure and the fixing insertion hole when the pipe outside the quick connector is stressed and bent, so that the sealing ring is prevented from being stressed to deform. Therefore, the problem of the water leakage caused by the deformation of the sealing ring can be avoided.
Description
Technical field
The utility model relates to a kind of rapid pipe joint of the environment that is applied to paddle, and refers in particular to the rapid pipe joint that prevents seepage in a kind of appliance water water purifier (machine) equipment, belongs to the family expenses RO water purifier accessory technical field of paddling.
Background technique
Rapid pipe joint is called again the push-in type pipe fitting, but because of its simple operation, connect the advantages such as perfect compact and Reusability and be applied to a lot of fields.
In the environment of paddling, in a lot of appliance water water purifiers (device), the connection between the pipeline is also used rapid pipe joint and is realized, the various water purification machines favored of Consumer widely especially in recent years, as; Family expenses reverse osmosis (reverse osmosis) water purifier, Reverse Osmosis Technology: the reverse osmosis original text is that REVERSEOSMOSIS(is called for short RO), principle is to apply the pressure larger than naturally osmotic pressure at raw water side, make water molecule by the high side's reverse osmosis of concentration to the low side of concentration.Usually; the Hyperfilevation water purifying machine is by 2 active carbon filter cores of 1 molten blown filter of PPF (1 active carbon particle, 1 sintering activity charcoal) etc.; former water is carried out pre-filtering; again to pre-filtering water exert pressure (passing through suction booster) make it be ten thousand/reverse osmosis membrane of micron by pore size, i.e. RO film.Being connected of pipeline all is to use rapid pipe joint between each filter core, between filter core and the RO film, between filter core and water inlet and OR film and the water outlet etc.Yet, limit by whole water purifier volume, the arrangement of filter core is very compact, therefore each pipeline usually is in by powerful crooked state, add in the upper pipeline pressure of current larger, in the course of time, cause the interior seal ring of fast connector because of monolateral stressed the distortion, outside tube is inserted when passing seal ring in the quick-acting joint, normal conditions are that internal diameter of the seal ring is slightly less than tube outer diameter, to keep closely cooperating of pipe and seal ring, that is to say, if being vertical forward insertion, pipe passes seal ring, then the stressed of internal diameter of the seal ring periphery is uniform, even distortion also is homogeneous deformation, still keeping seal ring and pipe along the state that closely cooperates on every side, can not leak.If pipe inserts and to pass after the stressed bending of seal ring then can cause seal ring to be in similar monolateral stress, and then cause sealed ring deformation inhomogeneous and produce water leakage phenomenon.As shown in Figure 1, seal ring be subjected to the long-term crooked compressing seal ring of pipe to add and be subjected to seasonal difference variation and expand with heat and contract with cold after burn-in effects, cause sealed ring deformation, gradually lose seal action and cause the seepage phenomenon, thereby causing product to leak not only brings inconvenience to the user afterwards, more seriously might can infiltrate in suction booster and other the circuit connection by water, cause motor damage, or cause whole set equipment to leak and can't use.
Therefore, solve above-mentioned rapid pipe joint seepage water problem, have important practical significance.
The model utility content
The purpose of this utility model is to provide the special use of a kind of family expenses RO water purifier to prevent the rapid pipe joint of seepage, with after solving pipeline and rapid pipe joint being connected, makes sealed ring deformation cause the seepage water problem because tube bending causes monolateral compressing.
The special use of a kind of family expenses RO of the utility model water purifier prevents the rapid pipe joint of seepage, and it comprises body 1, seal ring 2, fixed structure 3, block 4, clip 5, buckle 7; Wherein, body 1 is that an inside is with the cylindrical shell of cavity, be the stepped ramp type through hole at the one end, have for the fixed jack 11 that inserts outside tube in the bottom of this stepped ramp type through hole, the diameter of this fixed jack 11 is little than the diameter of cavity, and then forming a step 12, seal ring 2 is positioned over this step 12 places; The internal diameter of seal ring 2 is slightly less than the external diameter of outside tube 6, closely cooperates so that outside tube 6 passes to reach mutually behind the seal ring 2.Set gradually on request again fixed structure 3, block 4, clip 5 and the buckle 7 that can allow pipe 6 pass in up the stepped ramp type through hole.
Wherein, the degree of depth of fixed jack 11 is deepened, make it greater than 2mm.
When the pipe 6 of outside planted the fixed jack 11 that enters intensification interior after, be fixed jack 11 and fixed structure 3 these two places of pipe 6 are fixedly embraced, when pipe 6 is subjected to external force and when crooked, be positioned at the pipe of rapid pipe joint inside (being cavity) owing to fix and clenched at be fixed jack 11 and fixed structure 3 these two places, so that therebetween seal ring 2 can because of monolateral stressed the distortion, so just not avoid seal ring 2 to produce the seepage water problem because of distortion.
Wherein, the degree of depth of described fixed jack 11 is less than or equal to 10mm.
Wherein, described fixed structure 3 is a tubular structure.
Wherein, described fixed structure 3 can further be provided with a flange 31, and this flange 31 is connected to realize the location with the bottom of block 4.
Wherein, described flange 31 is bonding or welding with the Placement of the bottom of block 4.
Wherein, described fixed structure 3 and body 1 are by clamping or are spirally connected or welding or bonding mode are connected.
Wherein, described fixed structure 3, its internal diameter is consistent with the internal diameter of fixed jack 11.
Wherein, described stepped ramp type through hole, its internal diameter and the degree of depth will be complementary with size and the requirement of built-in accessories.This accessory comprises seal ring 2, fixed structure 3, block 4 etc.
The global shape of described rapid pipe joint (also being the global shape of body 1) can be on the market general " one " type (two ports are arranged), " L " type (two ports are arranged), T-shape (three ports are arranged), " Y " type (three ports are arranged), " ten " type (four ports are arranged), comprise and be applied in supercharging pump head two ends fast-type socket, fast-type socket solenoid valve, fast-type is high/low to compress switch, fast-type waste water ratio (water limiting valve), various fast ball valves and fast-type flow transducer are used in pipe-line equipment that rapid pipe joint connects etc. the device with being connected.Adopt the structural type of rapid pipe joint at which or which port, set according to actual needs.It all is the structural type of rapid pipe joint that all of the port is also arranged.If this port is not the structural type of rapid pipe joint, then adopt usual manner to connect, such as closely pin joint, interlocking, clamping etc.
