Description
Technical Field
The utility model relates to the technical field of pipelines, concretely relates to negative pressure liquid suction pipeline that can bending forming wantonly.
Background
Generally, since the diameter of the metal tube is not reduced in a state of generating a large negative pressure inside, the vacuum pump or the liquid injection device is provided with a vacuum or negative pressure liquid suction pipeline which is formed by processing the metal tube. However, the metal tube is not easily bent and formed during installation, or the installation interface is difficult to align after pre-bending and forming, which makes the equipment difficult to manufacture.
In order to improve the phenomenon, a connected metal tube is replaced by a 316L stainless steel capillary tube, certain strength is kept, meanwhile, certain toughness is achieved, and manual bending can be conducted according to requirements.
Disclosure of Invention
The utility model aims at providing a structure is light and handy, connect closely, the dismouting is convenient, durable's negative pressure liquid suction pipe way that can bending forming wantonly.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a negative pressure liquid suction pipeline that can be bending forming wantonly, from the bottom up includes screw thread formula filter screen, the built-in pipette of box, the external connecting pipe of box in proper order, and screw thread formula filter screen and the terminal spiro union of the built-in pipette of box, the built-in pipette top of box and the terminal spiro union of the external connecting pipe of box.
Furthermore, a stud is welded at the tail end of the pipette in the box body, the threaded filter screen and a nut are welded into a whole, and the nut and the stud are fixed in a threaded mode.
Furthermore, a threaded mounting joint is welded at the top end of the pipette arranged in the box body, a capillary tube welding joint is arranged at the tail end of the connecting pipe arranged outside the box body, a nut movable joint is welded on the capillary tube welding joint, and the nut movable joint is fixed with the threaded mounting joint in a threaded manner.
Furthermore, a sealing gasket is arranged at the joint of the nut movable joint and the thread mounting joint.
Further, the built-in pipette of the box body and the external connecting pipe of the box body are both stainless steel thin-walled pipes.
Compared with the prior art, the utility model, have following advantage:
the utility model relates to a negative pressure liquid suction pipeline that can be bending forming wantonly, the structure is light and handy, connects closely, and the dismouting is convenient, durable.
The box body built-in pipette and the box body external connecting pipe are made of stainless steel materials, have certain toughness and flexibility compared with metal, can define the bending size by user, and reduce the production and assembly difficulty; compared with nonmetal, the high-pressure vacuum pump has stronger durability and stronger bearable negative pressure capacity.
The threaded filter screen is installed through threads, and is convenient to disassemble and assemble. Particularly, a 60-mesh filter screen is adopted, so that solid impurities can be greatly reduced to enter a pipeline, and the liquid path is prevented from being blocked.
The design of the nut union makes the direction of the flexible pipe adjustable, and the butt joint of the interfaces is convenient.

Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The utility model discloses the pipeline that will be used for extraction vacuum or negative pressure imbibition converts stainless steel capillary into by the tubular metal resonator for the pipeline still has certain toughness when keeping certain intensity, still manually bends the pipeline. Specifically, the stainless steel capillary tube can be divided into an inner part and an outer part of a box body (a vacuum pump or a liquid injection device), a built-in pipette is arranged in liquid in the box body, and an external connecting pipe facilitates the butt joint of the outer part and other interfaces.
As shown in fig. 1 and 2, the negative pressure liquid suction pipeline capable of being bent and formed at will sequentially comprises a threaded filter screen 1, an internal liquid suction pipe 2 of a box body and an external connecting pipe 3 of the box body from bottom to top, wherein the internal liquid suction pipe 2 of the box body and the external connecting pipe 3 of the box body are stainless steel thin-wall pipes, 316L stainless steel is specifically adopted, the inner diameter of the internal liquid suction pipe 2 of the box body is 8mm, and the thickness of the pipe wall is 0.8mm. The arrangement enables the internally-arranged pipette 2 and the externally-arranged connecting pipe 3 of the box body to have certain strength while having the capability of bending and deforming. The threaded filter screen 1 is in threaded connection with the tail end of a pipette 2 arranged in the box body, and the top end of the pipette 2 arranged in the box body is in threaded connection with the tail end of a connecting pipe 3 arranged outside the box body. Specifically, a stud is welded at the tail end of a pipette 2 arranged in the box body, the threaded filter screen 1 and a nut are welded into a whole, and the nut and the stud are fixed in a threaded mode; the top end of the box built-in pipette 2 is welded with a thread mounting joint 4, the tail end of the box external connecting pipe 3 is a capillary tube welding joint, the capillary tube welding joint is welded with a nut loose joint 5, the nut loose joint 5 is fixed with the thread mounting joint 4 in a threaded manner, and a sealing gasket 6 is arranged at the joint of the nut loose joint 5 and the thread mounting joint 4, so that the sealing effect between the box built-in pipette 2 and the box external connecting pipe 3 is realized.
The thread type filter screen 1 is a 60-mesh filter screen, so that solid impurities can be greatly reduced from entering a pipeline to cause liquid path blockage.
The connecting end of the structure is fixed through the screw joint, and the disassembly and the assembly are convenient.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the concept of the present invention, and these modifications and decorations should also be regarded as within the protection scope of the present invention.
