Abstract
The utility model provides a kind of plastics hard pipeline fluid and 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.This device plays and supplements gas in pipe, balance tube internal pressure, the effect of protective conduit.
Description
Technical field
The utility model relates to a kind of plastics hard pipeline fluid and carries 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.
Model utility content
For above-mentioned defect and the problem of prior art, the utility model object 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 beneficial effects of the utility model are, 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, play 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.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, disclosed in the utility model
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 embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model 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.
