Abstract
The invention discloses a quick joint for gas and liquid filling. The quick joint comprises a first shell and a second shell, wherein the first shell is integrally made from a metal material, and is provided with an accommodation cavity; the accommodation cavity is provided with a first opening and a second opening; a valve head, a helical spring elastically pressed against the valve head and a spring support frame are sequentially arranged in the accommodation cavity; the second shell is in threaded connection with the first shell, is integrally made from a metal material, and is provided with a passage in which a mandrel is arranged. The quick joint is simple in structure, and material, process, using and maintenance cost is greatly reduced; the mandrel is arranged in an inner cavity of the joint, so that the volume of filled gas and liquid in the inner cavity is effectively reduced, a gas and liquid inlet passage is improved, and gas and liquid supply stability is enhanced; therefore, the quick joint is a product with high technical performance and economy.
Description
[technical field]
The present invention relates to the filling rapid pipe joint of a kind of gas-liquid.
[technical background]
At present in the joint that gas-liquid is filling, as supplied in the note fluorine operation of air-conditioning, joint connection note fluorine pipe carries out injecting rear generation note fluorine and leaks general at about 5 grams, show that main cause is that the surplus fluorine of tab through-hole discharges through technical reason analysis.
Therefore, I have developed the filling rapid pipe joint of a kind of gas-liquid.
[summary of the invention]
Object of the present invention technical problem to be solved to provide a kind of gas-liquid filling rapid pipe joint, it have structure simple, greatly decline with material, technique, operation and maintenance cost, utilize the advantage of structure to be discharged by gas-liquid pouring process and realize combustion with minimal.Therefore, it is the product that a kind of technical and Economy all has superior function.
To achieve these goals, the technical solution used in the present invention: the filling rapid pipe joint of a kind of gas-liquid, it comprises:
First housing; It adopts metallic material to make integrative-structure, the receiving cavity that described first housing has, and described receiving cavity has the first opening and the second opening, the helical spring, the spring bracing that are equiped with valve head in described receiving cavity successively, flexibly support with described valve head;
Second housing; Itself and described first housing bolt, described second housing adopts metallic material to make integrative-structure, and described second housing has passage, the built-in mandrel of described passage.
In one or more embodiment of the present invention, described mandrel has connecting head, and described connecting head has spaced first breach and the second breach.
In one or more embodiment of the present invention, described connecting head has spaced first through hole and the second through hole.
The present invention compares produced beneficial effect with background technique:
Present invention employs technique scheme, it have structure simple, greatly decline with material, technique, operation and maintenance cost, the mandrel of employing is placed in joint inner chamber, effectively reduces the capacity of the gas-liquid after noting at inner chamber, improve into gas-liquid channel simultaneously, make it strengthen for gas-liquid stability.Therefore, it is the product that a kind of technical and Economy all has superior function.

In describing the invention, it should be noted that, for the noun of locality, if any term " " center ", " transverse direction ", " longitudinal direction ", " length ", " width ", " thickness ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", " outward ", " clockwise ", indicating positions such as " counterclockwise " and position relationship are based on orientation shown in the drawings or position relationship, only for the ease of describing the present invention and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with particular orientation structure and operation, restriction concrete protection domain of the present invention can not be interpreted as.
In addition, if any term " first ", " second " only for describing object, and instruction or hint relative importance can not be interpreted as or imply the quantity indicating technical characteristics.Thus, be limited with " first ", " second " feature can express or implicit comprise one or more this feature, in the present description, the implication of " several " is two or more, unless otherwise expressly limited specifically.
In the present invention, except as otherwise clear stipulaties and restriction, should go to understand as broad sense if any term " assembling ", " being connected ", " connection " term, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Also can be mechanical connection; Can be directly be connected, also can be connected by intermediary, can be that two element internals are connected.For those of ordinary skills, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
In invention, unless otherwise prescribed and limit, fisrt feature second feature it " on " or D score can comprise the first and second features and directly contact, also can comprise fisrt feature and second feature and not be directly contact but by the other characterisation contact between them.And, fisrt feature second feature " on ", " under " and " above " comprise fisrt feature directly over second feature and oblique upper, or be only represent the height of fisrt feature level height higher than second feature.Fisrt feature second feature " on ", " under " and " below " comprise fisrt feature immediately below second feature or tiltedly below, or only represent that fisrt feature level height is lower than second feature.
Below in conjunction with the accompanying drawing of specification, by being further described the specific embodiment of the present invention, make technological scheme of the present invention and beneficial effect thereof clearly, clearly.Be exemplary below by embodiment is described with reference to the drawings, be intended to explain the present invention, and can not limitation of the present invention be interpreted as.
Please refer to shown in Fig. 1-3, the embodiment that the present invention preferably provides is the filling rapid pipe joint of a kind of gas-liquid, and it comprises: the first housing 1; It adopts metallic material to make integrative-structure, the receiving cavity 11 that described first housing has, described receiving cavity 11 has the first opening 111 and the second opening 112, the helical spring 13, the spring bracing 14 that are equiped with valve head 12 in described receiving cavity 11 successively, flexibly support with described valve head 12.
Second housing 2; Itself and described first housing 1 bolt, described second housing 2 adopts metallic material to make integrative-structure, and described second housing has passage 21, the built-in mandrel 22 of described passage 21.Described mandrel 22 has connecting head 23, and described connecting head 23 has spaced first breach 231 and the second breach 232.Described connecting head 23 has spaced first through hole 233 and the second through hole 124.
During work, mandrel 22 is plugged in crestal injection liquid pipe, after implant operation completes, due to the existence of mandrel 22, the accommodating gas-liquid amount in passage 21 is reduced greatly, thus gas-liquid discharge amount is declined, to in the operation of the note fluorine of air-conditioning during concrete implementation and operation, discharge amount decreases the note fluorine discharge of 85%, and note fluorine injects flow speed stability, simple and quick.
