Description
Technical field
The present invention relates to a kind of gas sealing mechanism of split-type air conditioner indoor set.
Background technology
It is one important procedure after the air conditioner assembling is finished in the air conditioner production that the air-tightness of air conditioner detects.The method that the air-tightness of air conditioner detects is that air conditioner is advanced in air conditioner refrigerating medium (as freon) perfusion, is increased to certain air pressure then, checks whether air conditioner leaks gas.As shown in Figure 1, the split-type air conditioner indoor set pipe joint 2 that mainly is connected by body 1 with condenser pipe in the indoor apparatus of air conditioner is formed, and pipe joint 2 is used for when installation indoor set being connected with off-premises station.The bubble-tight method of detection indoor apparatus of air conditioner that present people generally adopt is: copper pipe 18 1 ends are connected with pipe joint 2, gas-adding pipe 19 with filling machine docks with the other end of copper pipe 18 then, perfusion detects gas, pressurization, copper pipe 18 is clamped in order to avoid detect the gas escape with pliers again, back out gas-adding pipe 19, with welding manner the openend of copper pipe 18 is shut then, decontroled pliers again, again indoor set is sent at last and detected its gas tightness.Whole testing process needs many people to carry out because complex procedures, thus time-consumingly take material again, and go wrong easily and influence the complete machine quality; When air conditioner needed to be communicated with off-premises station and indoor set in client's hand, copper pipe 18 will be dropped, and causes waste of material, and when opening copper pipe 18, the residual air in the air conditioner can escape into atmosphere and pollute.Complex procedures, the time-consuming material of expense again and gas injection can't reclaim and contaminated environment when therefore, the gas sealing mechanism of existing split-type air conditioner indoor set carried out the gas tightness detection in the air conditioning chamber.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide a kind of indoor apparatus of air conditioner carry out gas tightness when detecting simple, the saving of work and time of operation material-saving and gas injection can reclaim and the gas sealing mechanism of the split-type air conditioner indoor set that do not pollute the environment again.
The technical solution adopted in the present invention is: the present invention includes be connected with condenser pipe in the indoor apparatus of air conditioner body pipe joint and perfusion air throttle, described perfusion air throttle is by valve body, spool, spring, spring base, connector, sealing gasket and conical gasket are formed, one section periphery of described valve body is made as polygonal post, another section periphery is made as taper shape, be provided with a ladder through hole in the described valve body, described ladder hole is formed cylindrical hole by I macropore that is positioned at described polygonal shell of column and the I aperture that is positioned at described conical section, be provided with screw thread in the described I macropore, axial two ends external diameter was provided with the I step degressively in the middle part of described spool was served as reasons, II step and III step, the circular shaft of IV step, described II step external diameter matches with described I aperture, described II stepped ends is provided with the taper round platform, described sealing gasket is arranged at described I step periphery, described taper round platform passes from described I aperture, described spool cooperates with described valve seal by described sealing gasket, described spring base is one to be provided with the through hole step circular shaft of aperture greater than described IV step external diameter in it, described IV step penetrates in the hole of described spring base, described spring is arranged between described spring base and the described spool and an end is enclosed within the periphery of described III step, the other end is enclosed within the small end of described spring base, one section portion's periphery of described connector is made as polygonal post, another section periphery is cylindrical and is provided with screw thread, the cylindrical hole that the through hole of described connector is made up of II macropore that is positioned at described polygonal shell of column and the II aperture that is positioned at described cylindrical section, be provided with screw thread in the described II macropore, be provided with a tapering transition face between described II macropore and the described II aperture, described conical gasket is arranged on the described tapering transition face, the cylindrical section of described connector is connected by thread seal with the polygonal shell of column of described valve body, and described connector is connected with the big end of described spring base.
Described valve body, described spool, described spring base, described connector are made by plastic material.
The invention has the beneficial effects as follows: because the present invention is sealedly connected with the perfusion air throttle on pipe joint, one end periphery of valve body is the pyramid type post, II stepped ends on the spool is provided with the taper round platform, when in carrying out the gas tightness testing process, needing to indoor apparatus of air conditioner perfusion detection gas, can make the perfusion air throttle can be easy to filling machine on gas-adding pipe seal butt joint mutually, after backing out gas-adding pipe, perfusion air throttle upper valve core can be from the movable sealing air conditioner under the effect of spring, saved the effective welding rod of soldering copper, this work can a people be finished, so operation is simple, saving of work and time is material-saving again, thereby and reduce problem points and improve the complete machine quality; Since before air conditioner is installed can by the perfusion air throttle with machine in residual air extract out earlier, detection residual air escapes into atmosphere and contaminated environment in the machine so can not make; Again owing to valve body, spool, spring base, connector are made by plastic material, so saved material cost.
