Abstract
The invention discloses a high-pressure movable elbow, relating to a pipeline connection elbow. The high-pressure movable elbow comprises a connection pipe A, a connection pipe B and a connection pipe C, which are sequentially connected; the connection pipe B and the connection pipe C are quarter arcs; a front joint of the connection pipe is connected with one end of a pipeline to be connected; a back joint of the connection pipe A is provided with a positive thread; the positive thread is matched with a negative thread on a front joint of the connection pipe B, so that the connection is realized; a negative thread is arranged on a back joint of the connection pipe B, and is matched with a positive thread on a front joint of the connection pipe C, so that the connection is realized; a back joint of the connection pipe C is connected with the other end of the pipeline to be connected; a cavity is arranged between the back joint of the connection pipe A and the front joint of the connection pipe B; a cavity is arranged between the back joint of the connection pipe B and the front joint of the connection pipe C; and a sealing gasket is arranged inside the cavity. The high-pressure movable elbow provided by the invention has the beneficial effects that full-direction adjustment of the connection pipes can be realized, and furthermore, no high-pressure leakage can be ensured by the specific arrangement of the sealing gasket. Therefore, the high-pressure movable elbow can be suitable for the connection conditions of various high-pressure large-caliber pipelines.
Description
Technical field
The present invention relates to field of mechanical technique, further is pipeline connecting bend, especially high-pressure-movable bend.
Background technique
Some pipeline junctions need connecting bend, to connect the pipeline of various directions.For the pipeline of general pressure, usually adopt flexible pipe to connect.But because liquid (or gas) pressure is larger in some pipelines, the larger pipeline of bore particularly, such as the pipeline of diameter more than 10 centimetres, flexible pipe can't be competent at.
Summary of the invention
The objective of the invention is to overcome defects, a kind of high-pressure-movable bend is provided, the pipeline that it can adapt under the high-pressure situations connects.
The objective of the invention is to realize by following scheme:
A kind of high-pressure-movable bend, comprise connecting tube A, the connecting tube B, the connecting tube C that connect successively, it is characterized in that: connecting tube B, connecting tube C all are the quadrant arc, connecting tube A front connector is connected in an end of pipeline waiting, be provided with external screw thread on the joint behind the connecting tube A, with the female thread in the connecting tube B front connector, realize connecting; Be provided with female thread on the joint behind the connecting tube B, match with external screw thread in the connecting tube C front connector, realize connecting; Joint is connected in the other end of pipeline waiting behind the connecting tube C; Between joint behind the connecting tube A and connecting tube B front connector, be provided with a cavity, between joint behind the connecting tube B and connecting tube C front connector, be provided with a cavity, the built-in sealing gasket of cavity.
Further:
The structure of described sealing gasket is: internal radius is identical with the internal diameter of connecting tube, and the annulus outer vertically is extended with curved edge, and curved edge concaves and is the C font, the curved curved edge seat that is provided with along the bottom.
The material of described sealing gasket is comprised of butadiene acrylonitrile rubber, Buddhist glue, a kind of of silica gel.
The invention has the beneficial effects as follows: because connecting tube B, connecting tube C all be the quadrant arc, and without hindrance 360 degree rotate, thereby can realize the comprehensive tuning of connecting tube, and high-pressure non-leakage is guaranteed in the setting of sealing gasket uniqueness.Thereby can adapt to various larger caliber high pressure pipe line connections.
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is structural representation of the present invention, and Fig. 2 is sealing gasket schematic representation of the present invention.
Among the figure: connecting tube A1, connecting tube A front connector 11, joint 12 behind the connecting tube A, connecting tube B2, connecting tube B front connector 21, joint 22 behind the connecting tube B, connecting tube C3, and connecting tube C front connector 31, joint 32 behind the connecting tube C, sealing gasket 4, annulus 41, curved along 42, curved along seat 43.
Embodiment
Embodiment:
As shown in Figure 1 and Figure 2, comprise connecting tube A1, the connecting tube B2, the connecting tube C3 that connect successively, connecting tube B2, connecting tube C3 all are the quadrant arc, connecting tube A front connector 11 is connected in an end of pipeline waiting, be provided with external screw thread on the joint 12 behind the connecting tube A, with the female thread in the connecting tube B front connector 21, realize connecting; Be provided with female thread on the joint 22 behind the connecting tube B, match with external screw thread in the connecting tube C front connector 31, realize connecting; Joint 32 is connected in the other end of pipeline waiting behind the connecting tube C.
Joint 12 and 21 of connecting tube B front connectors are provided with a cavity behind connecting tube A, joint 22 and 31 of connecting tube C front connectors are provided with a cavity behind connecting tube B, the built-in sealing gasket 4 of cavity, the structure of sealing gasket 4 is: annulus 41 internal diameters are identical with the internal diameter of connecting tube, annulus 41 outers vertically are extended with curved along 42, curved concaving along 42 is the C font, the curved curved edge seat 43 that is provided with along 42 bottoms.
Because curved concaving along 42 is the C font, fluid pressure is larger, and it supports tightlyer to two ends, seals tighter.Therefore can realize and with pressurely to turn to.
During operation, turn connecting tube B2 and connecting tube C3, can realize the comprehensive tuning of connecting tube, thereby can adapt to various pipeline connections.
The material of described sealing gasket is a kind of of butadiene acrylonitrile rubber, Buddhist glue, silica gel.
The present invention is not limited to above-mentioned preferred embodiments, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technological scheme with the present invention, all belongs to protection scope of the present invention.
