Abstract
The utility model discloses a pipeline connector which can cause the operating process to become simple and convenient, which comprises a connector body. A valve cavity and an outlet opening communicated with the valve cavity are arranged in the connector body, a pushing rod type valve is arranged in the valve cavity; and a clamping pin is arranged on the connector body. The pipeline connector is mainly used as the connector for a plurality of pipelines.
Description
Technical field
The utility model relates to the interface that is used to connect various pipelines.
Background technique
As everyone knows, in the process of gas holder, the gas of residue in the gas cylinder or gasification need be discharged to outside the bottle,, thereby guarantee carrying out smoothly of inflation so that the maintenance of the pressure in the gas cylinder is constant to the gas cylinder inflation.Do not allow to discharge or useful composition owing to contain in the gas of discharging, thereby must use gas-returning devices that the gas of the discharge in the gas cylinder is got back in the gas holder.As shown in Figure 1, the present gas-returning devices that uses, its structure comprises: the stop valve 1 that is used to open and close pipeline be connected flexible pipe 4, the inlet of stop valve 1 is communicated with gas cylinder, the outlet of stop valve 1 is connected with threaded coupling 3 by inipple 2 with being connected between the flexible pipe 4, and the other end that connects flexible pipe 4 is connected with gas holder.This threaded coupling in the gas-returning devices and the Placement of inipple itself use cumbersome, and also will open stop valve after pipeline connects; And after inflation finishes, close stop valve again earlier, threaded coupling could be drawn off from inipple.So just make that the whole operation process is cumbersome, and the manufacture cost of whole gas-returning devices is also higher.
The model utility content
Technical problem to be solved in the utility model is: a kind of pipe interface easy to use, that also can reduce cost is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: pipe interface comprises: interface body, and the outlet that is provided with valve pocket in the interface body and communicates with valve pocket is provided with the post rod type valve in the valve pocket; Described interface body is provided with bayonet lock.
The concrete structure of above-mentioned post rod type valve is: be provided with spacing platform in the valve pocket, spacing platform is provided with valve seat, valve seat is provided with through hole, activity is equipped with push rod in the valve seat, the front portion of push rod is provided with annular boss, and annular boss is provided with the keying seal ring that matches with the valve pocket import, is set with spring on the push rod, the two ends of spring are pressed on respectively on annular boss and the valve seat, and valve pocket is stretched out at the top of push rod.
The beneficial effects of the utility model are: the utility model is by being provided with bayonet lock on interface body, and easy post rod type valve is set in interface body, make interface with when joint is connected, valve is opened automatically, greatly facilitate the connection and the use of pipeline, but also reduced the manufacture cost of whole gas-returning devices.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 2, pipe interface described in the utility model, comprise: interface body, this interface body is made of interface that is set together by set screw nut 3 anterior 1 and interface rear portion 2, be provided with valve pocket 11 in the interface body, and the outlet 21 that communicates with valve pocket 11, in the present embodiment, also be provided with transition passage 12 between valve pocket 11 and the outlet 21, be provided with the post rod type valve in the valve pocket 11, its structure comprises: be arranged on the piston type valve seat 4 in the valve pocket 11, valve seat 4 is provided with a plurality of through holes---and the valve pocket 11 that these a plurality of through holes will be positioned at valve seat 4 both sides is communicated with, valve seat 4 is abutted together with the spacing platform 22 that is arranged on valve pocket 11 bottoms, activity is equipped with push rod 5 on the valve seat 4, the front portion of push rod 5 is provided with annular boss, is set with the keying seal ring 7 that matches with the import of valve pocket 11 on the annular boss, is set with spring 6 on the push rod 5, the two ends branch of spring 6 adds and is pressed on annular boss and the valve seat 4, and interface front portion 1 is stretched out from the import of interface front portion 1 in the top of push rod 5; Interface front portion 1 is provided with bayonet lock 8---and this bayonet lock 8 forms loose joint FERRULETYPE structure with the cutting ferrule 31 of pipe joint 30.In the present embodiment, the end at described interface rear portion 2 also is provided with and is used for the outside thread 23 that is connected with gas cylinder.
The utility model is provided with bayonet lock 8 by interface body, and easy post rod type valve is set in interface body, make pipe interface when being connected with pipe joint 30, interface front portion 1 can be placed the inner chamber of cutting ferrule 31, and the chute 311 of bayonet lock 8 on the cutting ferrule 30 screwed in, finally be locked in the bayonet socket 312 of chute 311 bottoms; And in the screw-in process of bayonet lock 8, push rod 5 is owing to the obstruction that is subjected to the push rod 32 in the pipe joint 30 bounces back, make annular boss and be arranged on the import that keying seal ring 7 on the annular boss leaves valve pocket 11 gradually to make valve pocket 11 inlet/outlet be connected, promptly valve is opened; And after inflation finishes, can easily bayonet lock 8 be screwed out from the chute 311 of cutting ferrule 31, in the back-out process of bayonet lock 8, push rod 5 resets, and opens and closes seal ring 7 to form with the import of valve pocket 11 once more and seal, that is: valve closing.Like this, greatly facilitate the connection and the use of pipeline, and, the manufacture cost of whole gas-returning devices also reduced.
