Abstract
The utility model relates to an articulated pipe connector for a hydraulic pipeline. The articulated pipe connector comprises an articulated body, an articulated bolt, an upper sealing ring and a lower sealing ring, the articulated body is tee-shaped, the articulated bolt is inserted into a through hole in one side of the articulated body, a threaded portion of the articulated bolt is positioned outside the articulated body, a blind hole in the other side of the articulated body is an oil opening D, a blind-hole-shaped center oil channel A is axially formed in the threaded end of the articulated bolt, and a penetrating cross-shaped through-flow hole B is radially formed in the middle of the articulated bolt. The articulated pipe connector is characterized in that an annular oil channel C is formed in the matched position of the oil opening D of the articulated body and the articulated bolt, two end openings of an upper through hole of the articulated body are respectively inside small and outside large flared, the upper sealing ring is positioned at the flared position of the upper end opening of the upper through hole of the articulated body in a matched manner, and the lower sealing ring is positioned at the flared position of the lower end opening of the upper through hole of the articulated body in a matched manner. By additionally arranging the annular oil channel C, the through-flow area is enlarged, pressure loss is reduced, and the problem of unreliable sealing is solved by improving a sealing structure.
Description
Technical field
The utility model belongs to hydraulic system technical field, is specifically related to the pipe joint for hydraulic pipe line.
Background technique
Hydraulic pipe line is a kind of pipe joint form conventional in hydraulic system with hinged pipe joint, and the hydraulic fluid port direction that when its major advantage is installation, hinged pipe joint is connected with pipeline can regulate, and after installing, pipe joint height is lower, is convenient to arrange.In actual use, hinged pipe joint exists the pressure loss large to the hinged pipe joint of prior art, and bonded washer needs the artificial concentricity of adjusting with hinge bolt, does not easily cause sealing reliability high and occur the phenomenon of pipe joint seepage.
Summary of the invention
The problem that the pressure loss is large, sealing reliability is not high existing in order to solve existing hinged pipe joint, the utility model, by architecture advances, provides a kind of hinged pipe joint for hydraulic pipe line.
Concrete improvement technological scheme is as follows:
Hinged pipe joint for hydraulic pipe line comprises articulated body, hinge bolt, upper seal ring and lower seal, described articulated body is threeway tubulose, hinge bolt is inserted in a side through hole of articulated body, the helical thread portion of hinge bolt is positioned at the outside of articulated body, and the opposite side blind hole of articulated body is hydraulic fluid port D; The threaded end of described hinge bolt is axially arranged with the central oil passage A of blind hole shape, and the hinge bolt middle part footpath corresponding with the hydraulic fluid port D of articulated body upwards offers criss-cross through flow hole B of being of perforation; Described upper seal ring is located at the upper end-hole of through hole and the cooperation place of hinge bolt on articulated body, described lower seal is located at respectively the lower end mouth of through hole and the cooperation place of hinge bolt on articulated body, and improvement is: on the through-hole wall of the articulated body corresponding with blind hole, offer articulated body circular groove; On the external cylindrical surface of the hinge bolt corresponding with through flow hole B on hinge bolt, offer circular groove, the circular groove on described articulated body circular groove and hinge bolt has formed ring shaped oil passage C; On described articulated body, the two-port of through hole is respectively inner small and outside big horn mouth; Described upper seal ring and lower seal are O-ring seals, and upper seal ring coordinates the horn mouth place of the upper end-hole that is positioned at through hole on articulated body, and lower seal coordinates the horn mouth place of the lower end mouth that is positioned at through hole on articulated body.
Useful technique effect of the present utility model embodies in the following areas:
1. by setting up ring shaped oil passage C, increase the flow area of hinged pipe joint, reduced the pressure loss of pipe joint;
2. use the self contering structure of O-ring seals, the concentricity that solved artificial adjustment Sealing and hinge bolt is inaccurate and cause insecure problem that seals.
Accompanying drawing explanation
Fig. 1 is the utility model structure External view.
Fig. 2 is the sectional view of Fig. 1.
Sequence number in upper figure: articulated body 1, hinge bolt 2, upper seal ring 3, lower seal 4.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Referring to Fig. 1 and Fig. 2,
Hinged pipe joint for hydraulic pipe line comprises articulated body 1, hinge bolt 2, upper seal ring 3 and lower seal 4.Articulated body 1 is threeway tubulose, hinge bolt 2 is inserted in a side through hole of articulated body 1, the helical thread portion of hinge bolt 2 is positioned at the outside of articulated body 1, for the hydraulic fluid port that is connected to hydraulic element is installed, the opposite side blind hole of articulated body 1 is hydraulic fluid port D, on the through-hole wall of the articulated body 1 corresponding with blind hole, offers articulated body circular groove.The threaded end of hinge bolt 2 axially offers the central oil passage A of blind hole shape, the hinge bolt 2 middle part footpaths corresponding with the hydraulic fluid port D of articulated body 1 upwards offer criss-cross through flow hole B of being of perforation, on the external cylindrical surface of the hinge bolt 2 corresponding with through flow hole B, offer circular groove, the circular groove on described articulated body circular groove and hinge bolt 2 has formed ring shaped oil passage C; On articulated body 1, the two-port of through hole is respectively inner small and outside big horn mouth, and upper seal ring 3 and lower seal 4 are O-ring seals; Upper seal ring 3 is installed on the cooperation place of horn mouth and the hinge bolt 2 of the upper end of through hole on articulated body 1, and described lower seal 4 is located at respectively the horn mouth of the lower end of through hole and the cooperation place of hinge bolt on articulated body.
The cooperation place of articulated body 1 and upper seal ring 3, lower seal 4 is the first seal face, the cooperation place of hinge bolt 2 and upper seal ring 3, lower seal 4 is the second seal face, between the lower end surface, hexagon side of hinge bolt 2 and the hydraulic fluid port upper-end surface of hydraulic element, forms the 3rd seal face.
