Abstract
The invention discloses an automatic-flow-limiting pipe connector, and belongs to the technical field of connecting pipe fittings. The pipe connector comprises pipe base sleeves with through holes. A circular concave cavity coaxial with each through hole is formed in one end of the corresponding pipe base sleeve. The ends, provided with the circular concave cavities, of the two pipe base sleeves are connected. A valve element connected with the inner wall of a valve cavity through a spring is arranged in the valve cavity formed by the two circular concave cavities. The other ends of the pipe base sleeves are sleeved with pipes through respective sealing sleeves respectively. By means of the pipe connector, the problems that existing pipe connection is complex in cooperation, the flow of conveyed media can not be controlled, reliability is poor, the media are prone to leakage, and the service life is influenced can be solved.
Description
Technical field
The present invention relates to connection pipe fitting technical field, especially a kind of automatic current limiting joint be connected for pipeline.
Background technique
Pipe joint is the necessary part that media-carrying lines connects, and what existing pipe joint adopted is base sleeve or the rigid plastics base sleeve that two ends install the metal of pipeline respectively, utilizes adhesive material or heating to make them connect; But this Placement also exists: its bonding complicated operation is loaded down with trivial details, and the flow of fed sheet of a media is uncontrollable, and poor reliability, easily media leaks occurs, and affects the problem in working life.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic current limiting pipe joint, it is loaded down with trivial details that this pipe joint can solve existing pipe connecting operations complexity, and the flow of fed sheet of a media is uncontrollable, poor reliability, easy generation media leaks, affects the problem in working life.
In order to solve the problem, the technical solution adopted in the present invention is: this automatic current limiting pipe joint, comprise the base sleeve with through hole, described base sleeve one end offers the circular-shaped, concave cavity coaxial with described through hole, described base sleeve is two that circular-shaped, concave cavity end is connected, and is provided with the spool that spring is connected with described valve pocket inwall in the valve pocket of these two described circular-shaped, concave cavity formations; The described base sleeve the other end is sleeved in pipeline respectively by respective stuffing box gland.
In technique scheme, technological scheme can also be more specifically: described spool is corresponding to being located at described through hole, and described stuffing box gland inwall offers the scrobicular ring corresponding to pipeline outer wall annular protrusion, and described stuffing box gland outer wall is provided with annular protrusion.
Further: described base sleeve one end outer wall is provided with land, two described base sleeves are fixedly connected with by the bolt be installed on its land.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, because base sleeve is set to two, the land that these two base sleeves are arranged by its outer wall is fixedly connected with bolt, easy disassembly, improves maintenance efficiency;
2, owing to being provided with stuffing box gland between base sleeve and pipeline, stuffing box gland inwall offers the scrobicular ring corresponding to pipeline outer wall annular protrusion, stuffing box gland outer wall is provided with annular protrusion, base sleeve, frictional force between pipeline and stuffing box gland can be improved, what make them bind round each other does not tightlier depart from, good airproof performance, long service life;
3, owing to being provided with the valve pocket that circular-shaped, concave cavity is formed, the spool that spring is connected with described valve pocket inwall in valve pocket, is provided with; Can according to the size of cavity volume ingress flow, by connecting the spring volitional check chamber outlet place flow of piston.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Automatic current limiting pipe joint shown in Fig. 1, comprise the base sleeve 3 with through hole, base sleeve 3 one end all offers the circular-shaped, concave cavity coaxial with through hole, base sleeve 3 for circular-shaped, concave cavity end be connected two, these two circular-shaped, concave cavity form valve pocket 7, and be provided with spool 6 corresponding in the valve pocket 7 of through hole, spool 6 is connected with spring 5 one end, spring 5 the other end is fixed on valve pocket 7 inwall away from spool 6, and base sleeve 3 the other end is sleeved in pipeline 1 respectively by respective stuffing box gland 2; Stuffing box gland 2 inwall offers the scrobicular ring 23 corresponding to pipeline outer wall annular protrusion, and stuffing box gland 2 outer wall is provided with annular protrusion 22; The diameter of the annular protrusion 21 of outermost end is greater than the diameter of inner annular protrusion 22, and base sleeve 3 one end outer wall is provided with land 8, and two base sleeves 3 are fixedly connected with by the bolt 4 be installed on its land 8.
The present invention mounts and dismounts conveniently, good sealing effect, long service life, and can according to the size of cavity volume ingress flow, by connecting the flow at the spring volitional check chamber outlet place of piston.
