Abstract
The utility model relates to a rapid connector used for an air conditioner, which is a male connector (2) spliced and matched with a female connector (1). A diffuser (21) with the function of a forcer at the front end is fixedly arranged in the connector end of a male connector connecting pipe body (25), a valve seat (26) matched with a valve core (22) is arranged in the connecting pipe body (25), the valve core (22) is positioned between the valve seat (26) and an inner dummy club (231), when the male connector and the female connector are in the connecting state, a valve core (13) in the female connector leaves the valve seat because the valve core (13) is propped and pressed by the diffuser (21) of the male connector (2), and the pressure air fluid flowing from the female connector forces the valve core (22) in the male connector (2) to leave the valve seat (26) to cause the male connector to be communicated with the female connector. The valve core of the male connector of the air conditioner is under the free state without a spring required, the opening and the closing are related to the pressure at both ends, and the problem of unsmooth flow caused by the elasticity difference of the spring is avoided.
Description
Technical field
The utility model relates to air-conditioning, particularly a kind of fast connector that is used for A/C evaporator.
Background technique
Air conditioner needs the sealability of its refrigerant pipe is tested repeatedly in manufacturing and maintenance process.Be in the refrigerant pipe of interior machine, to charge into the nitrogen leak detection earlier, charge into helium leak check and charge into refrigeration agent at last to carry out gas welding and seal leak detection at present to the test mode of split-type air conditioner indoor set.In said process, if find that gas leakage is arranged, the release of then need exitting is tested after repairing pipeline again.Prior art has a kind of rapid pipe joint, and it comprises tool joint pin and the female joint that stuffing box gland is connected together, and is equipped with spring in the pin and box sub, is resisted against on the valve seat at the effect lower valve core of spring, with joint sealing.When the needs pin and box sub was communicated with, both headed in opposite directions, and two spools all separate with valve seat, and the gap between gap between spool and the valve seat and spool and the joint tube wall constitutes air-flow or liquid chunnel.The problem that this structure exists is: necessarily require the spring force in the pin and box sub identical, if there are differences, the spool of the joint that elastic force is little separates fully with valve seat, the spool of the joint that elastic force is big does not separate with valve seat or does not separate fully, cause circulation not smooth, directly influence the proper testing of air-conditioning.And the spring that there are differences occurs in the product of regular meeting at different batches.
The model utility content
The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of air conditioner fast connector that can avoid the influence of difference spring is provided.
The purpose of this utility model can realize by following technical proposal: a kind of fast connector of air conditioner, be the tool joint pin that cooperates with the female joint grafting, it is characterized in that in the interface end of tool joint pin adapter body, setting firmly the fluid director that front end has the top effect, take in the body valve seat that cooperates with spool is arranged, spool is between valve seat and inner convex platform, when tool joint pin and female joint are in coupled condition, the roof pressure of the tool joint pin fluid director that the spool in the female joint is subjected to and the spool in it is lifted off a seat, the pressure gas-liquid that flows out from female joint forces the interior spool of tool joint pin to be lifted off a seat, thereby tool joint pin and female joint are communicated.
Spool in the described tool joint pin is made of the radial wing plate portion of the conus portion at top and afterbody, and both are made into integration by plastics.
Described valve seat is flush-mounted in to be taken in the body, takes in the body and also installs interior pipe, and push up mutually with valve seat interior pipe upper end, and push up mutually with O-ring seals the lower end, the inwall of pipe in above-mentioned inner convex platform is formed on.
Above-mentioned valve seat is to be made by plastics or rubber.
Fluid director in the above-mentioned tool joint pin is wing plate radially, and its center is the pipe body, and the outer of wing plate is connected with adapter body interface end inwall and is made into integration by plastic injection-moulded.
The radial wing plate of described spool and fluid director is both wings or three wings or four wing structures.
Spool in the tool joint pin makes the blind hole of hollow by also being made up of the conus portion at top and the columnar portion of afterbody in the columnar portion, the hole wall has radial direction through hole and is interlinked to the outside in making, and the hole connects and composes one-way valve structures along covering one deck diaphragm and by screw.
The fast connector of this air conditioner links together tool joint pin and female joint in the process of installing an air-conditioner, and makes extraneous air to enter in the refrigeration system.When tool joint pin is connected with female joint, tool joint pin is moved to female joint, the radial wing plate center circle of the fluid director of tool joint pin body is with the fore-set roof pressure on the female joint spool, this roof pressure makes spool break away from valve seat after making every effort to overcome the elastic force of obeying the female joint spring, tool joint pin and female joint are on state all, thereby make gas-liquid to flow.After tool joint pin and female joint broke away from, female joint was subjected to the elastic force of spring to make spool and valve seat closure, tool joint pin be subjected to its afterbody high-pressure medium effect with spool and valve seat closure, can not leak separately.If needing to repair refrigerant pipe also can inflate repeatedly, need not to change this valve and gas welding and seal during test, easy to operate.Compared with prior art, the tool joint pin spool of the fast connector of this air conditioner need not spring and is in free state, and it opens and closes only relevant with the pressure at spool two ends, has avoided the influence of elastic force difference of spring and the smooth problem of circulation that causes.
