Description
Technical field
The utility model relates to refrigeration technology field, more particularly, relates to a kind of air-conditioning tube connector.
Background technology
Split type domestic air conditioning generally is made up of indoor set and off-premises station, couples together through tube connector between the two, forms cooling cycle system.As shown in Figure 1; Usually the tube connector fixed form is to pack into the nut of respective diameters at the tube connector two ends then two ends copper pipe enlarging (the enlarging diameter is about 1.2 times of copper pipe diameters); Nut can landing like this, the tightly interlock and play the effect that is tightly connected of nut and valve body screw thread and evaporimeter input and output pipe joint screw thread.When installing an air-conditioner, must hand-held two spanners, a spanner is used for fixing joint, and another is used for rotary nut and can tightly be connected tube connector with valve body, evaporimeter joint, and is very bothersome.Do not have packing ring to seal between horn mouth and valve body, the joint, only lean on nut compressing copper pipe horn mouth and joint taper surface to seal, if tube connector is through after moving perhaps air-conditioning long-time running, horn mouth goes out to be easy to endurance failure, is prone to cause Lou fluorine situation.
Deposit, be mixed with foreign matter in the pipeline in the transportation for fear of air-conditioning, therefore general air-conditioning valve body import and export, the tube connector mouth of pipe, evaporimeter input/output port all should design closing device, for example add sealing plug.But because air conditioner connecting pipe, evaporimeter is not a vacuum state, also need vacuumize when therefore installing an air-conditioner or with the air of arranging in the outdoor machine system refrigerant in the removal system, could open high-low pressure valve body spool.Therefore this type of air-conditioning installs quite loaded down with trivial detailsly, and cost is also high.
The utility model content
The utility model purpose provides a kind of air-conditioning tube connector in order to overcome the deficiency that above-mentioned prior art exists, at the end connection famale connector of tube connector; Said famale connector is made up of pedestal, famale connector and jacket casing, and said pedestal and famale connector are tightly connected, and joint needle and back-moving spring are set in the said famale connector; Said joint end is provided with valve port; Said back-moving spring is arranged in the joint, and said joint needle is located between valve port and the back-moving spring, and said jacket casing is located at the end of famale connector.
Said joint is connected with base thread, and at the two ends that are threaded the 3rd seal washer, the 4th seal washer is set.
Said joint inside is provided with the spring limiting stand, and said back-moving spring one end is resisted against on the spring limiting stand, and the other end is resisted against on the joint needle.
Said joint needle top is a frustum, and the valve port place of said joint is provided with and the suitable conical surface of joint needle top frustum cone side.
The valve port inboard of said joint is provided with first seal washer, and said joint inside is provided with the needle limiting stand, and said joint valve Aculeata is provided with the spacing ring corresponding with the needle limiting stand, and spacing ring is provided with second seal washer.
The valve port outside, said famale connector end is provided with the conical cavity that is used for the male contact conical surface seal, is provided with taper washer at the conical cavity inwall.
The built-in sleeve spring of said sleeve; Said sleeve can slide along the famale connector cylindrical, is provided with the location snap ring of sleeve in the end of famale connector, and the inwall of said sleeve is provided with ramp; The end of said famale connector is offered two Spring Card film traps at least; In the Spring Card film trap spring card is set, a side of spring card is stretched to sleeve and is smoothly ridden against on the ramp, and stretch out to the inboard of famale connector from the opening of Spring Card film trap the end of spring card.
Compared with prior art, the utlity model has following advantage:
1. dual-seal effectively prevents coolant leakage;
2. the employing needle valve structure makes things convenient for installation and maintenance.

Fig. 1 is the structural representation of the famale connector of the utility model;
Fig. 2 is the structural representation of the male contact of the utility model;
Fig. 3 is that two joints of the utility model connect sketch map.
The specific embodiment
A kind of air-conditioning tube connector of the utility model comprises famale connector and male contact.
Famale connector is as shown in Figure 1, comprises sleeve 1, joint 2, pedestal 3, copper pipe 4.
Because the male contact 5 that the famale connector of the tube connector structure of the utility model need match connects, and just realizes being tightly connected of pipe-line system.As shown in Figure 2, this male contact 5 comprises male contact needle 51, first seal washer 52, needle limiting stand 53, second seal washer 54, back-moving spring 55, the 3rd seal washer 56, spring limiting stand 57, positioning convex ring 58.Link 6 is connected with the internal thread of male contact 5 through the interior external screw thread of establishing.Link 6 inside are provided with spring limiting stand 57, and back-moving spring 55 1 ends are pressed on the spring limiting stand 57, and the other end is pressed on the male contact needle 51.Male contact needle 51 tops are round platform, and male contact 5 open tops are provided with and the suitable conical surface in its side, and inside is provided with the needle limiting stand 53 corresponding with the tail structure of male contact needle 51.Male contact 5 open top inboards are provided with first seal washer 52, and the bottom side of needle limiting stand 53 is provided with second seal washer 54, and the link 6 externally threaded bottoms of valve body are provided with the 3rd seal washer 56.Also be provided with positioning convex ring 58 on the joint shell, be used for external packing ring is fixed on joint.
Famale connector is as shown in Figure 3 with being connected of male contact 5; Male contact needle 51 backs down with famale connector needle 22 each other, and male contact 5 top annular fillet surfaces are close to taper washer 21, has only space between the needle between male and female connector as passage; Refrigerant is able to circulation, forms kind of refrigeration cycle.During connection, slide the sleeve 1 of famale connector toward pedestal 3 directions, the radially expansion outward of spring card 13 this moment, male contact 5 can directly inject in the famale connector, and two joints match the back and decontrol sleeve 1.Sleeve 1 is set back by sleeve spring 12 tension force effects, and spring card 13 is radially shunk by sleeve 1 inboard compression inwards, blocks the positioning convex ring 58 of male contact.Positioning convex ring 58 is designed with a ring washer, both can play sealing function, and spring card 13 is stuck on the positioning convex ring 58 more firmly.Sleeve 1 can not get loose because of being located the screens of snap ring 11 easily.
Famale connector adopts identical hermetically-sealed construction with male contact 5: when joint breaks away from connection status or is in closed state; The pressure of butt joint disappears; The elastic force of back-moving spring adds that the pressure from refrigerant is pressed on first seal washer and second seal washer joint needle tightly; Double-layer seal prevents secondary refrigerant leakage.
