Abstract
The invention discloses a movable pipe valve joint for a high-pressure pipeline, which comprises a female head, wherein a bent pipe is arranged at the end part of the female head, the bent pipe inwards forms an annular recess, a plurality of steel balls in an annular array are arranged in the upper end of the annular recess, a pipe hoop head is arranged on the female head, an annular cavity matched with the steel balls is arranged in the pipe hoop head, and a clamping groove is arranged at the end part of the annular cavity; the tip of public head is equipped with the pipe chute, and the end of pipe chute even has the buckle, and when public female head was connected, the head embedding of buckle was in annular cavity, and the butt on the lateral wall of steel ball, and the tail end joint of buckle is in the draw-in groove. The movable connection between the pipelines is realized through the connection of the male and female heads. Compared with the existing movable pipe valve joint, the movable pipe valve joint is more efficient in connection, faster in connection speed and better in sealing effect.
Description
Technical Field
The invention relates to a movable pipe valve joint for a high-pressure pipeline.
Background
In the use of the pipeline, a movable pipe valve joint is needed to connect the adjacent pipelines, and an aluminum buckle or a plastic fastener is generally adopted to fix the adjacent pipelines.
However, in a high-pressure pipeline, the connection mode has a great safety hazard, and when the internal pressure of the pipeline is too high, the pipe joint expands outwards, so that problems such as leakage and the like are caused. To this kind of condition, integral type coupling can be fine link to each other the pipeline, and integral type coupling can convert the pressure of pipeline inside into the clamp force to the sealing washer to promote the sealed effect of coupling.
However, the integral pipe joint has problems of high cost, complex installation method and the like, so that the integral pipe joint is difficult to be widely adopted in practical use due to the problem of manufacturing cost. Aiming at the problem, the split type pipe joint has the advantages of high connection speed and low single-piece cost, but the common split type pipe joint has the defects of large number of parts and unsatisfactory sealing effect.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a movable pipe valve joint for a high-pressure pipeline.
The technical scheme of the invention is as follows: a movable pipe valve joint for a high-pressure pipeline comprises a male head and a female head which are matched with each other;
the pipe hoop head is arranged on the female head, an annular cavity matched with the steel balls is arranged inside the pipe hoop head, and a clamping groove is formed in the end part of the annular cavity;
the tip of public head is equipped with the pipe chute, and the end of pipe chute even has the buckle, and when public female head was connected, the head embedding of buckle was in annular cavity, and the butt on the lateral wall of steel ball, and the tail end joint of buckle is in the draw-in groove.
Preferably, the pipe hoop head is connected with the female head through welding.
Preferably, the end of the buckle is provided with a circular arc transition.
Preferably, the tail through pipe of the female head is made of cast iron.
Preferably, the tail through pipe of the male head is made of cast iron.
Preferably, the tail part of the buckle is provided with a notch, and the cross section of the notch is in a shape of a right triangle.
Has the advantages that:
the movable connection between the pipelines is realized through the connection of the male and female heads. After the connection, under the combined action of the internal pressure of the pipeline and the inclined pipe, the bent pipe elastically deforms upwards, so that the steel ball is pressed, and in turn, the steel ball also presses the bent pipe and the inclined pipe, so that the bent pipe and the inclined pipe are attached more tightly.
Simultaneously, when the buckle was embedded in the draw-in groove, the head butt of buckle was on the lateral wall of steel ball to prevent that the steel ball rearward movement from leading to the public female head to connect not hard up.

FIG. 1 is a schematic structural view of a female head;
FIG. 2 is a cross-sectional view of the male and female connectors when connected;
FIG. 3 is a cross-sectional view of the male portion;
1. the female head 2, the pipe hoop head 3, the steel ball 4, the bent pipe 5, the inclined pipe 6 and the buckle.
