Abstract

The utility model relates to a quick-acting joint of separated air-conditioning coupling, which is composed of a copper tube welded joint and two separated connecting assemblies. The copper tube welded joint is connected with two separated connecting assemblies. Each inner chamber of the connecting assembly is provided with a spring base, a spring, a valve core, a valve cap and a sealing element which are connected together through a cap nut collar and have two seal to protect leakage through a sealing ring. The structure can connect and separate at any time according to the requirement of the refrigeration industry. When connected, the utility model can open automatically, and when disconnected, the utility model can close automatically, so the operation is very convenient. The sealing device in the channel makes freon at the leakage prevention state in a long term circulation process, and the sealing device reduces the waste of energy resource greatly.

Description

Quick-acting joint of separated air-conditioning coupling

The utility model relates to the quick fastening means in the refrigeration industry, especially for the fastening means in the split type air-conditioning equipment.

Fastening meanss such as the leak test of split-type air conditioner equipment, pressure testing, perfusion fluorine Lyons, used joint of past is old-fashioned dead soldered splice, be that copper tube soldered splice and copper tube are welded to connect, this connecting means can not be dismantled separation, so need transportation together, install together, use together, this transportation to Subscriber Unit, installation are all made troubles, and air-conditioning equipment often needs annual maintenance once, need block the circulation in fluorine Lyons during maintenance, otherwise the outflow of a large amount of fluorine Lyons causes energy waste.

The purpose of this utility model is to provide one to be convenient to dismounting, separation in order to overcome deficiency of the prior art, can open automatically during connection, and the split-type air conditioner that can cut out automatically during disengaging connects rapid pipe joint.

Fig. 1 is the utility model opening state structure sectional view.

Embodiment is described in detail below in conjunction with accompanying drawing.

With reference to Fig. 1: the utility model split-type air conditioner connects rapid pipe joint and utilizes the one-way valve principle design to form, and connects into the integral body that can dismantle, separate by two connection parts in two ends copper tube soldered splice 1.Connecting sleeve 2 inner chambers of a connection part are equipped with spring seat 4, this spring seat 4 has six pin, be three and hug the sky spring abutment towards what first three backwards became to intersect uniform arrangement, spool 3 is arranged in spring seat 4, the other end of spool 3 is equipped with Sealing 7, bonnet 6, spring 5, and the outer cone size of spool 3 heads is consistent with the female cone in connecting sleeve 2 apertures.Connecting head 12 inner chambers of another connection part are equipped with spring seat 4, spool 3, Sealing 7, bonnet 6, spring 5 equally, the outer cone size of spool 3 heads is same consistent with the female cone in connecting head 12 apertures, on spool 3, compress into Sealing 7 and bonnet 6 during assembling earlier, overlap upper spring 5 and spring seat 4 again, make three pin of spring seat 4 because elasticity is sticked into connecting sleeve 2, in the interior omoplate of connecting head 12.Connecting sleeve 2 is Spielpassung with connecting head 12, at its matching part two road seal rings 8,9 is set, and causes the seepage phenomenon when preventing the circulation of fluorine Lyons.Connection 2 after the combination, connecting head 12 with nut 10 be connected with back-up ring 11, stop bit, prevent that nut 10 is outer sliding because the effect of connecting head 12 cylindrical omoplates and back-up ring 11, making nut 10 to rotate can not move.

The two ends of connecting sleeve 2, connecting head 12 are connected with copper tube soldered splice 1 taper pipe thread.

When split type air-conditioning equipment need connect, connecting head 12 is inserted in the connecting sleeve 2, pull nut 10, connecting sleeve 2 is moved to right, at this moment two ends spool 3 pushes up mutually and leaves position, corresponding to aperture, form passage and can make the circulation of fluorine Lyons, if in the time of need breaking away from because of factors such as maintenance or detections, oppositely pull nut 10, connecting sleeve 2 just withdraws from, and two spools 3 are closed the aperture automatically under the promotion of spring 5, and fluorine Lyons, two ends promptly is plugged, at this moment, can transport, install, maintenance, work such as detection.

Quick-acting joint of separated air-conditioning coupling according to the utility model design, can at any time connect on demand or separate, overcome and leaveed no choice but in the past the defective that two bodies transport simultaneously, install simultaneously, for the transportation of refrigeration industry split-type air conditioner equipment, installation, maintenance, detection, perfusion fluorine Lyons etc. bring convenience, improved working efficiency, this is simple in structure, easy to operate, can make to guarantee long-term no leakage state in the filling process of fluorine Lyons, reduce energy waste.
