Abstract
The invention provides an anti-vacuum automatic air sucking device for fluid conveyance of a plastic hard pipeline. The anti-vacuum automatic air sucking device comprises a conveying pipeline and an air sucking valve device, wherein the air sucking valve device is arranged at the top of the pipeline positioned at a highest point or an air closing point of the conveying pipeline, and air is sucked through valve opening. The anti-vacuum automatic air sucking device achieves the effects of supplementing the air in a pipe, balancing the pressure in the pipe and protecting the pipeline.
Description
Technical field
The present invention relates to a kind of plastics hard pipeline fluid and carry the automatic suction means of anti-vacuum
Background technique
The flowing mediums such as current mud (sand) slurry carry the plastics hard pipeline used all not install Aspirating valves, when carrying the flowing mediums such as mud (sand) slurry, when the fed sheet of a media cutout of upstream, due to the inertia force of drop and flow velocity, fed sheet of a media in upstream tube can not stop immediately, still by certain flow velocity flow further downstream, tonifying Qi can cannot form vacuum in pipe, produce negative pressure in pipe, pipeline is inhaled flat and is damaged.
Summary of the invention
For above-mentioned defect and the problem of prior art, the object of the invention there is provided one and plays gas in supplementary pipe, and balance tube internal pressure, the plastics hard pipeline fluid of the effect of protective conduit carries the automatic suction means of anti-vacuum.
A kind of plastics hard pipeline fluid carries the automatic suction means of anti-vacuum, comprises conveyance conduit, lubricant supplying apparatus, and lubricant supplying apparatus is installed at described conveyance conduit peak or the pipeline top of holding one's breath a little, absorbs gas by the unlatching of valve.
The invention has the beneficial effects as follows, plastics hard pipeline fluid carries the automatic suction means of anti-vacuum, when there is vacuum in conduit running process pipe, by the unlatching suction gas of Aspirating valves, plays the effect of balance tube internal pressure; There is the plurality of advantages such as structure is simple, easy for installation, protection pipe shaft, minimizing maintenance, increase engineering efficiency.

Embodiment
Below in conjunction with accompanying drawing of the present invention, be clearly and completely described technological scheme of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, disclosed by the invention
During the flowing mediums such as mud (sand) slurry conveying plastics hard conduit running, when the fed sheet of a media cutout of upstream, due to the inertia force of drop and flow velocity, the fed sheet of a media in upstream tube can not stop immediately, still can by certain flow velocity flow further downstream, tonifying Qi cannot form vacuum in pipe, produce negative pressure in pipe, in valve pocket, fed sheet of a media declines, Exhaust Open, because external atmospheric pressure is greater than system pressure, ambient atmos enters system by intakeport, maintains overpressure balance.
2, structure composition; Linkage section flange, water stop spacer, Aspirating valves.
3, structure mounting steps and effect:
(1), first at pipeline rise and fall the pipeline top at high some place along the line, and opening welding tee, plays the effect of connecting tube and valve and fixed valve;
(2) water stop spacer installed by threeway flange plate, after mounting, valve is played to the effect of sealing;
(3), after water stop spacer installation, carry out the installation of Aspirating valves, by the overpressure of the whole fluid line of balance, guarantee pipeline inherently safe.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with the protection domain of claim.
Claims (1)
1. plastics hard pipeline fluid carries the automatic suction means of anti-vacuum, comprises conveyance conduit, lubricant supplying apparatus, and lubricant supplying apparatus is installed at described conveyance conduit peak or the pipeline top of holding one's breath a little, absorbs gas by the unlatching of valve.
