Abstract
The utility model provides a novel air-conditioning machine unit needle valve core replacing device. The novel air-conditioning machine unit needle valve core replacing device comprises a four-way component, handles and a needle valve head, wherein the handle I is arranged on the upper part of the four-way component; a valve core buckling opening is formed in the bottom of the handle I; the handle II is arranged on the left side of the four-way component; the handle I and the handle II are provided with rubber sealing plugs; a needle valve cap is arranged on the lower part of the four-way component; the handle I can rotate and can be drawn. The novel air-conditioning machine unit needle valve core replacing device has the advantages that the needle valve core can be quickly replaced under the condition that Freon is not lost, the whole replacing process is very short in time, the operation is simple, convenient and quick, the working efficiency is improved, and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to more changing device of a kind of air-conditioning, more changing device of especially a kind of air-conditioning unit valve core of needle valve.
Background technique
Large Central Air Conditioning System unit is all with the needle-valve head of several filled freon, and the spool of the inside is easily damaged parts, and spool will leak fluorine after damaging, because fluorine system all cannot directly be changed with 5-20 kilogram of pressure valve core.While at present changing spool, there are two kinds of selections: 1, direct freon emptying, the freon in relatively large unit is worth several thousand units even up to ten thousand and had not only wasted money but also befouling environment.2, self-contained maintenance person can reclaim most of freon by fluorine recycling machine, approximately needs 3-12 hour but whole recovery adds that follow-up filled process wastes time and energy.
Model utility content
The purpose of this utility model is to provide more changing device of a kind of air-conditioning unit valve core of needle valve for fear of the deficiencies in the prior art.
The technical solution adopted in the utility model is: more changing device of a kind of air-conditioning unit valve core of needle valve, comprise four-way, handle, needle-valve head composition, described four-way top is provided with handle I, described handle I bottom is spool bayonet socket, four-way left side is provided with handle II, and handle I, handle II are with rubber seal plug, and four-way bottom is provided with needle-valve cap.
Described handle I is rotatable, can twitch.
The beneficial effects of the utility model are: on the basis of not losing freon, realize fast valve core of needle valve and change, the whole Renewal process used time is very short, simple and efficient to handle, has improved working efficiency, has alleviated staff's labor intensity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein 1 is four-way, and 2 is handle I, and 3 is spool bayonet socket, and 4 is rubber seal plug, and 5 is needle-valve cap, and 6 is handle II.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
More changing device of a kind of air-conditioning unit valve core of needle valve, comprise four-way 1, handle, needle-valve head composition, described four-way 1 top is provided with handle I 2, described handle I 2 bottoms are spool bayonet socket 3, four-way 1 left side is provided with handle II 6, and handle I 2, handle II 6 are with rubber seal plug 4, and four-way 1 bottom is provided with needle-valve cap 5.
Described handle I 2 is rotatable, can twitch.
The rubber seal plug of handle II 64 is extracted into four-way 1 left side, the rubber seal plug of handle I 24 is inserted into four-way 1 below, needle-valve cap 5 is screwed on needle-valve head, rotatable handle I 2 is backed out bad spool, twitch handle I 2 rubber seal plugs 4 and rest on four-way 1 top, handle II 6 is shifted four-way 1 place onto and is sealed freon, handle I 2 belt spools are extracted out, after changing spool, be inserted into the position as figure, handle II 6 is extracted into left side, insertion handle I 2 is rotated spool is screwed on, and handle assembly is just backed out and completed more and changed jobs, economic quick environmental protection.
Claims (2)
