Abstract
The utility model discloses a solve quick hydraulic joint pressure relief device, including body and handle, be equipped with the screw thread through-hole on the body, the handle middle part is equipped with the threaded rod, and the screw thread through-hole on threaded rod and the body constitutes the screw fit. The front part of the body is a forward extending joint, and the middle part of the excircle of the plug is provided with an annular groove. After the plug is inserted into the female buckle of the hydraulic joint, the groove is matched with the locking steel ball in the female buckle to axially limit the body. The utility model provides a because of hydraulic pressure pipeline pressure is big, the problem of the unable butt joint of quick-operation joint, the pressure release needle in the convenient top-moving box can unload the pressure in the hydraulic pressure pipeline fast, has realized hydraulic joint's quick butt joint.
Description
Technical Field
The utility model belongs to the technical field of the oil drilling and specifically relates to a quick hydraulic joint assists interfacing apparatus, quick hydraulic joint pressure relief device.
Background
Quick hydraulic joint on the hydraulic pressure pipeline divides pin thread and box, and the pressure release needle in the box is linked together by the pin thread top in the butt joint, realizes the hydraulic pressure transmission. However, the pressure in the female buckle pipeline is large, and the pressure relief needle in the female buckle is difficult to push when the male buckle is in butt joint, so that the male buckle cannot be in butt joint and inserted, the manual operation is difficult, and the butt joint of the joint is influenced.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, provide one kind and can unload the pressure in the hydraulic pressure pipeline fast, realized the quick hydraulic joint pressure relief device of the quick butt joint of hydraulic joint.
In order to solve the technical problem, the utility model discloses a following technical scheme:
The utility model provides a quick hydraulic joint pressure relief device, includes body and handle, is equipped with the screw thread through-hole along the axial on the body, and the handle middle part is equipped with the threaded rod, and the threaded rod constitutes the screw fit with the screw thread through-hole on the body. The front part of the body is a forward extending annular joint, and the middle part of the excircle of the plug is provided with an annular groove.
The above scheme further comprises: the body is hexagonal outside, and the screw thread through-hole is established on the body center pin, and the threaded rod constitutes T shape with the handle and is connected.
Compared with the prior art, the invention has the beneficial effects that: the problem of because of hydraulic pressure pipeline pressure is big, quick-operation joint can't the butt joint is solved, the convenient pressure release needle that pushes up in the box can unload the pressure in the hydraulic pressure pipeline fast, has realized the quick butt joint of hydraulic joint.

The labels in the figure are: 1. the novel pressure relief device comprises a body, 2, a handle, 3, a threaded rod, 4, a plug, 5, a groove, 6, a female buckle, 7, a pressure relief needle and 8, and a locking steel ball.
Detailed Description
The invention is described in further detail below with reference to the figures and the detailed description.
Referring to the attached fig. 1 and 2 of the specification, the quick hydraulic connector pressure relief device comprises a body 1 and a handle 2. The body 1 is in an external hexagonal shape, and a threaded through hole is formed in the central shaft of the body 1. The middle part of the handle 2 is provided with a threaded rod 3, the threaded rod 3 and the handle 2 form a T shape, and the threaded rod 3 and the threaded through hole on the body 1 form a spiral fit.
3 referring 3 to 3 the 3 specification 3, 3 fig. 3 3 3 is 3 a 3 cross 3- 3 sectional 3 view 3 of 3 the 3 quick 3 hydraulic 3 connector 3 pressure 3 relief 3 device 3 along 3 a 3 cross 3- 3 section 3 of 3 fig. 3 1A 3- 3 a 3 when 3 the 3 quick 3 hydraulic 3 connector 3 pressure 3 relief 3 device 3 is 3 inserted 3 into 3 a 3 female 3 buckle 3. 3 The front part of the body 1 is a forward extending plug 4, the plug 4 is annular, the middle part of the excircle of the plug 4 is provided with an annular groove 5, and after the plug 4 is inserted into a female buckle 6 of the hydraulic joint, the groove 5 is matched with a locking steel ball 8 in the female buckle 6 to axially limit the body 1.
When the quick hydraulic joint is used, the plug 4 is inserted into the female buckle 6 of the quick hydraulic joint, the locking steel balls in the female buckle 6 enter the grooves 5, and the body 1 forms axial limit relative to the female buckle 6. Use hexagonal spanner on one side to fix body 1, another side rotating handle 2 makes threaded rod 3 stretch forward, and when threaded rod 3 pushed up pressure release needle 7, hydraulic oil of hydraulic pressure pipeline revealed a little, and hydraulic pressure pipeline pressure descends, extracts plug 4 this moment, and the resistance of pressure release needle 7 descends, can normally dock quick hydraulic joint.
