Abstract
The utility model relates to a quick connector for air conditioner connecting tubes, which comprises a first connecting tube and a second connecting tube sealed and sheathed with each other, wherein the first and the second connecting tubes are respectively provided with a valve pin provided with an ejector column at the front end, and a spring, via the spring, the valve pin is abut against the valve base to form a seal structure. When in connection, the ejector columns of the two valve pins are ejected and pressed with each other, the two valve pins respectively move from relative valve bases, and the valve pins are processed as hollow blind pits whose walls are provided with radial through holes for communicating internal and external spaces. The valve pins and the joint tube wall of split air conditioner connecting tubes no demand clearance therebetween, airflow or liquid flow flows the radial through holes of the hollow valve pins of the connecting tube, the valve pins are axially arranged all the time. When there is abrasion between the valve pins and the surface of the valve bases, the O-shaped seal ring on the cone surface of the valve pins can keep good seal with the valve bases via the spring.
Description
Technical field
The utility model relates to air-conditioning, particularly a kind of quick connector of split-type air conditioner connecting tube.
Background technique
Split-type air conditioner has one and is loaded on indoor indoor set and one and is loaded on outdoor outdoor unit, is communicated with by two connecting tubes between indoor set and the outdoor unit.Make that under the effect of these two connecting tubes the refrigeration agent in the air-conditioning is circulated.In the process of split-type air conditioner was installed, that connecting tube connects was loaded down with trivial details, waste time and energy, in installation process, might make in the air-conditioning freezing medium leakage or make air enter in the refrigeration system of air-conditioning.
In order to address the above problem, prior art has a kind of split-type air conditioner rapid pipe joint, it comprises tool joint pin and the female joint that stuffing box gland is connected together, be provided with spring, movable sheath, central shaft in the female joint, central shaft is connected in the female joint, movable sheath is resisted against on the central shaft under the elastic force effect of spring, thereby female joint is sealed.Be provided with entity spool and spring in the tool joint pin, be resisted against on the valve seat of tool joint pin, tool joint pin is sealed at the elastic force effect lower valve core of spring.When spool separates with valve seat, gap between gap between spool and the valve seat and spool and the joint tube wall constitutes air-flow or liquid chunnel, if the elastic force off-axis of spring to, or reason such as vibrations makes the spool deflection, cause gap between spool and the joint tube wall to reduce or stop up, directly influence the proper functioning of air-conditioning.
In addition, because connecting tube connects frequently, the elastic force of spring is bigger again, is easy to generate wearing and tearing between spool and the valve seat, and sealing effect reduces and reduction of service life.
The model utility content
The purpose of this utility model is at existing in prior technology the problems referred to above, and the quick connector of the split-type air conditioner connecting tube of a kind of working stability, long service life is provided.
The purpose of this utility model can realize by following technical proposal: a kind of quick connector of air conditioner connecting pipe, comprise the adapter one that can seal socket mutually and take over two, in adapter one and adapter two, be equipped with spool and the spring that front end has fore-set, and the effect lower valve core roof pressure at spring constitutes sealing configuration on valve seat, the mutual roof pressure of fore-set that it is characterized in that two spools when adapter one is in coupled condition with adapter two, make these two spools leave separately valve seat respectively simultaneously, two spools all make into the blind hole of hollow, and the hole wall has through hole and is interlinked to the outside in making.
Described spool is made up of the conus portion of bottom and the columnar portion on top, and the blind hole of hollow makes in columnar portion, and the conical surface of conus portion is provided with O-ring seals.
Described O-ring seals can be arranged at the jointing place of the conus portion awl end and columnar portion.
Described spool is made by plastics or copper product.
Described fore-set is positioned at the cone tip part of spool conus portion, and it and spool are connected as a single entity.
Set firmly spring seat in the described adapter one, push up mutually with spool and spring seat respectively at the two ends of spring.
Described adapter two connecting leg that has been threaded, the two ends of above-mentioned spring push up mutually with spool and the spring seat that is fixedly arranged on the connecting leg port respectively.
Be provided with seal ring between described adapter one and the adapter two.
The quick connector of this split type air conditioner connecting pipe is located in the connecting tube of air-conditioning, in the process of installing an air-conditioner, will take over one with take over two and link together and get final product, make the refrigeration agent in indoor set and the outdoor unit can not leak, make also that simultaneously extraneous air can't enter in the refrigeration system.Take over one with after adapter two is connected, adapter one is moved to taking over two, the mutual roof pressure of fore-set on two spools, this roof pressure is made every effort to overcome the valve seat that makes spool disengaging adapter one and adapter two behind the elastic force of clothes spring, adapter one and adapter two all are on state, so just make connecting tube also be on state, thereby make refrigeration agent to flow.
Compared with prior art, need not retention gap between spool of this split type air conditioner connecting pipe and the joint tube wall, only need to keep and can smooth and easy slip get final product, air-flow or liquid flow from the radial direction through hole of the hollow valve core of taking over and flow through, and spool keeps stable axial configuration; Simultaneously, if spool and valve base surface produce wearing and tearing, the O-ring seals that is positioned on the spool conical surface can continue to keep good sealing with valve seat under the effect of spring, increases the service life.
