Abstract
The utility model discloses a pipeline joint which is convenient to use and is able to lower the cost. The pipeline joint is composed of a joint body. A cutting sleeve is arranged at the front part of the joint body, and a slide groove and a bayonet which are communicated are arranged in the cutting sleeve. A cuttage grafting channel and a valve cavity which are mutually communicated are arranged in the joint body, the cuttage grafting channel is communicated with the inner cavity of the cutting sleeve, and the valve cavity is communicated with the inlet which is arranged at the tail end of the joint body. A ring groove is arranged on the inner wall of the cuttage grafting channel, a leakproof seal ring is arranged in the ring groove, and an ejector pin type valve is arranged in the valve cavity. The pipeline joint is mainly used for the connection of pipelines.
Description
Technical field
The utility model relates to the joint 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: be used to open and close the stop valve 1 of pipeline and is connected flexible pipe 3, the outlet of stop valve 1 is continuous with an end that is connected flexible pipe 3, and the other end of connection flexible pipe 3 links to each other with inipple 2.During practical application, inipple 2 is connected with threaded coupling in being connected the gas cylinder pipeline, and the import of stop valve 1 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, inipple could be drawn off from threaded coupling.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 joint 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 joint, comprise: fittings body, the front portion of fittings body is provided with cutting ferrule, is provided with the chute and the bayonet socket that communicate in the cutting ferrule, is provided with the grafting passage and the valve pocket that are interconnected in the fittings body, and grafting passage and cutting ferrule intracavity inter-connection, valve pocket is connected with the import that is arranged on the fittings body afterbody, and the inwall of grafting passage is provided with annular groove, is provided with the leakproof seal circle in the annular groove; Be provided with the post rod type valve in the described valve pocket.
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 outlet of valve pocket, 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 the top of push rod is stretched in the grafting passage.
The beneficial effects of the utility model are: the utility model is provided with cutting ferrule by the front portion at fittings body, and easy post rod type valve is set in fittings body, makes joint with when interface is connected, and valve is opened automatically.So just 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 joint described in the utility model, comprise: fittings body, this fittings body is made of joint that is set together by set screw nut 3 anterior 1 and joint rear portion 2, the front portion of fittings body is that joint front portion 1 is provided with cutting ferrule 11, being provided with the chute 111 and the bayonet socket 112 that communicate in the cutting ferrule 11---this cutting ferrule 11 forms loose joint FERRULETYPE structure with the bayonet lock 31 of pipe interface 30, be provided with the grafting passage 12 and the valve pocket 21 that are interconnected in the fittings body, and grafting passage 12 and cutting ferrule 11 intracavity inter-connections, valve pocket 21 is connected with the import 22 that is arranged on the fittings body afterbody, the inwall of grafting passage 12 is provided with annular groove, is provided with leakproof seal circle 4 in the annular groove; Be provided with the post rod type valve in the described valve pocket 21, its concrete structure comprises: be provided with spacing platform 23 in the valve pocket 21, spacing platform 23 is provided with valve seat 5, valve seat 5 is provided with a plurality of through holes---and the valve pocket 21 that these a plurality of through holes will be positioned at valve seat 5 both sides is communicated with, activity is equipped with push rod 6 in the valve seat 5, the front portion of push rod 6 is provided with annular boss, annular boss is provided with the keying seal ring 8 that matches with the outlet of valve pocket 21, be set with spring 7 on the push rod 6, the two ends of spring 7 are pressed on respectively on annular boss and the valve seat 5, and the top 61 of push rod 6 is stretched in the grafting passage 12; The middle part of push rod 6 is provided with positive stop lug boss 62.
The utility model is provided with cutting ferrule 11 in the front portion of fittings body, and easy post rod type valve is set in fittings body, make pipe joint when being connected, can make bayonet lock 31 finally be locked in the bayonet socket 112 with the chute 111 of cutting ferrule 11 along bayonet lock 31 precessions with matching with pipe interface 30; In the precession process of cutting ferrule 11, push rod 6 is owing to the obstruction that is subjected to the push rod 32 in the pipe interface 30 bounces back, make annular boss and be arranged on the outlet that keying seal ring 8 on the annular boss leaves valve pocket 21 gradually, that is: valve is opened, and makes the inlet/outlet of valve pocket 21 be connected; And after inflation finishes, can easily cutting ferrule 11 be screwed out from bayonet lock, in the back-out process of cutting ferrule 11, push rod 6 resets, open and close seal ring 8 once more with valve pocket 21 go out interruption-forming sealing, valve closing.Like this, greatly facilitate the connection and the use of pipeline, but also reduced the manufacture cost of whole gas-returning devices.
