Abstract

The utility model relates to a shutoff valve for a separated air conditioner, being installed on the outdoor body of the separated air conditioner and being used for shutting off and shutting on the flow of the cooling (warming) medium. The structure of the shutoff valve mainly comprising a fluorin infusing mouth (1), a valve sleeve (2), a valve body (3), a valve core (4), a pipe cap (5), a joint nut (6) and a connecting pipe (7). The utility model is characterized in that the valve core (4) is positioned in the valve body (3) and is tightly connected with inner screw threads inside the valve body (3), the upper end of the valve core is provided with a cone body (16) on which a cylinder body (17) is arranged, and an O'-shaped rubber ring (12), a brass pad (13) and a locking nut (14) are arranged on the cylinder body (17). The product has the advantages that no matter the valve is shut off and shut on, the shutoff valve is sealed by a metal, the shutoff valve also uses the rubber ring as an auxiliary seal so as to effectively prevent the leakage of the freon medium, and users can also conveniently replace the rubber ring.

Description

Shutoff valve for seperate air conditioner

The utility model relates to a kind of special stop valve for double-body air conditioner, and it is contained on the outdoor body of detachable air conditioner, is used for ending and opening the mobile of refrigeration (system is warm) medium.

After the user purchases detachable air conditioner and installs, outdoor body is connected with special valve by a dedicated pipe with indoor body, after connecting, to vacuumize in the pipe, then the nut on the special valve is turned on, the freon medium is flowed in the device of junction chamber endosome, at this moment start the motor of compressor, air conditioner just enters normal refrigeration (system is warm) working state.Fluorine Lyons medium enter lead to indoor body pipeline in, also fill full whole valve body volume inside, for preventing the leakage of fluorine Lyons medium, in the stop valve valve body, rubber ring is set usually and seals.Its shortcoming is the seal with elastometic washer instability, fluorine Lyons year leakage rate is usually between 1.13 grams restrain to 5.65, be full of the whole valve body volume inside because of fluorine Lyons medium in addition, certain pressure and temperature are arranged, and after stop valve used a period of time, rubber ring can wear out and damage, fluorine Lyons promptly can be leaked, can't change because of rubber ring at all, a whole set of stop valve be scrapped, please the specialized maintenance personnel repair and debug then so have only.

The purpose of this utility model is to provide a kind of can prevent fluorine Lyons dielectric leakage, good seal performance, novel special stop valve for double-body air conditioner effectively.

Below in conjunction with drawings and Examples the utility model is described in detail.

The utility model is made up of fluorinfused nozzle (1), valve pocket (2), valve body (3), spool (4), pipe cap (5), Female connector fittings (6) and adapter (7).The upper end of valve body (3) is provided with valve core cap (10), and the lower end is located at fixed base (15), and fixed base (15) is connected with taking over (7), and there is a plug (11) outer end of taking over (7).One side of valve body (3) connects fluorinfused nozzle (1), and there is a pipe cap (5) at the opposite slightly to the right or left of fluorinfused nozzle (1), and pipe cap (5) is outer to be Female connector fittings (6), and Female connector fittings (6) is connected with the indoor body pipeline of detachable air conditioner.Spool (4) is positioned at valve body (3), and closely link to each other with the internal thread in the valve body (3), rise and open and flowing by pipeline refrigeration and the warm medium of system, there is a cone (16) its upper end, this cone (16) is by closely contacting with the interior right angle of valve pocket (2) when opening, one cylindrical body (17) is arranged on the cone (16), " O " type rubber ring (12) is enclosed within on the cylindrical body (17), and brass pad (13) and locking nut (14) are docile and obedient the top that preface is pressed in " O " type rubber ring (12) tightly.Valve core cap (10) is enclosed within on the conical surface of valve pocket (2), seals.

Advantage of the present utility model is: no matter (one) this valve is to cut out with opening to be metal sealing, also use rubber ring to make cambic auxiliary seal, during detachable air conditioner work, fluorine Lyons medium can the Long Term Contact rubber ring, and fluorine Lyons year leakage rate has prevented the leakage of fluorine Lyons medium effectively less than 0.2 gram; (2) this valve in use for some time, even rubber ring has damage, aging, the phenomenon that lost efficacy, the user also can change this rubber ring at any time easily, needn't ask special maintenance personal to place under repair.
