Abstract
The utility model discloses a kind of liquid from filling apparatus, it comprises wet tank, is series at the Venturi tube of conveyance conduit, and described wet tank is provided with for the liquid after-teeming mouth of liquid make-up, being positioned at liquid filling mouth bottom wet tank, being positioned at by connecting tube and Venturi tube bottom major diameter inner space the pressure balance mouth located above wet tank top liquid level by reduced diameter section inner space in the middle part of connecting tube and Venturi tube.When medium is by Venturi tube, certain static pressure is produced poor between its entrance and throat, this static pressure difference is utilized to form negative pressure, can by the liquid in storage tank with draw form automatic filling in natural gas vent line, play hygroscopic moisture, suppress the effect of hydrate, fast and be automatically injected liquid when pipeline emptying easily, natural gas line is avoided when emptying due to Hydrate Plugging pipeline that temperature drop is formed.
Description
Technical field
The utility model relates to natural gas line waterproof compound technology, particularly relate to a kind of for filling liquid to ducted liquid from filling apparatus.
Background technique
Liquid filling method general at present uses mechanical type filling, and equipment comprises liquid tank and liquid infusion pump, and its principle is that the liquid in liquid tank is noted into target location by liquid injection port after liquid infusion pump supercharging.The filling of liquid machine formula is divided into continuous and discontinuous two kinds of situations, needs the start and stop of Non-follow control injection pump and carry out adjust flux according to different user demands volume adjusted formula injection pump rotating speed under being wherein interrupted operating mode.
Before safety valve, the situation of filling liquid belongs to and is interrupted operating mode and energy automatic filling, this requires to detect safety valve downstream pressure or the flow signal as liquid infusion pump start and stop and separating valve opening and closing, and regulate injection amount according to concrete safety valve adjustment revolution speed, this can cause, and control logic is complicated to be postponed with filling action, therefore the liquid filling mode needing research easy more in time.
Summary of the invention
For the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of antifreezing liquid that is automatically injected in conveyance conduit, avoids the liquid of line clogging from filling apparatus.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of liquid is from filling apparatus, it comprises wet tank, is series at the Venturi tube of conveyance conduit, and described wet tank is provided with for the liquid after-teeming mouth of liquid make-up, being positioned at liquid filling mouth bottom wet tank, being positioned at by connecting tube and Venturi tube bottom major diameter inner space the pressure balance mouth located above wet tank top liquid level by reduced diameter section inner space in the middle part of connecting tube and Venturi tube.
Improve as the one of the utility model liquid from the technological scheme of filling apparatus, described wet tank is provided with pressure gauge.
Improve as the one of the utility model liquid from the technological scheme of filling apparatus, described wet tank is provided with floss hole.
Improve as the one of the utility model liquid from the technological scheme of filling apparatus, the connecting tube between liquid filling mouth and Venturi tube is provided with valve, and the connecting tube between pressure balance mouth and Venturi tube is also provided with valve.
Improve as the one of the utility model liquid from the technological scheme of filling apparatus, the connecting tube between described pressure balance mouth and described Venturi tube is horizontally disposed with the liquid level position making Venturi tube bottom higher than wet tank.
The beneficial effects of the utility model are: when medium is by Venturi tube, certain static pressure is produced poor between its entrance and throat, utilize this static pressure poor, can by the liquid automatic filling in storage tank in natural gas vent line, play hygroscopic moisture, suppress the effect of hydrate, fast and be automatically injected liquid when pipeline emptying easily, natural gas line is avoided when emptying due to Hydrate Plugging pipeline that temperature drop is formed.Utilize this device without the need to other large-scale storage tank and dispenser pump, do not need control system and power system, there is the features such as structure is simple, with low cost, simple to operate, stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of liquid of the utility model from filling apparatus embodiment.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of liquid of the utility model is from filling apparatus, it comprises wet tank 11, is series at the Venturi tube 21 of conveyance conduit, and described wet tank 11 is provided with for the liquid after-teeming mouth 12 of liquid make-up, being positioned at liquid filling mouth 15 bottom wet tank, being positioned at by connecting tube 22 and Venturi tube bottom major diameter inner space the pressure balance mouth 16 located above wet tank top liquid level by reduced diameter section inner space in the middle part of connecting tube 22 and Venturi tube.When medium is by Venturi tube, certain static pressure is produced poor between its entrance and throat, utilize the negative pressure that this static pressure difference is formed, can by the liquid in storage tank with draw form automatic filling in natural gas vent line, play hygroscopic moisture, suppress the effect of hydrate, fast and be automatically injected liquid when pipeline emptying easily, inject antifreeze liquid thus avoid natural gas line when emptying due to Hydrate Plugging pipeline that temperature drop is formed.Utilize this device without the need to other large-scale storage tank and dispenser pump, do not need control system and power system, there is the features such as structure is simple, with low cost, simple to operate, stable.
More preferably, described wet tank 11 is provided with pressure gauge 18, for observing the pressure in storage tank, is convenient to the state that the pressure in regulates liquid storage tank is extremely applicable to.
More preferably, described wet tank 11 is provided with floss hole 19, may be used for removing the sediments in wet tank 11.
More preferably, connecting tube 22 between liquid filling mouth 15 and Venturi tube 21 is provided with valve 23, connecting tube 22 between pressure balance mouth 16 and Venturi tube 21 is also provided with valve 23, close two valves 23 just can pull down wet tank 11 and carry out safeguarding or take off storage tank and transfer to other places and carry out liquid and supplement, opened by valve 23 in running at ordinary times and be in normally open, liquid make-up makes its antifreezing block pipeline at any time.
More preferably, connecting tube 22 between described pressure balance mouth 16 and described Venturi tube 21 is horizontally disposed with the liquid level position making Venturi tube 21 bottom higher than wet tank 11, makes only just to suck liquid from liquid filling mouth 15 when Venturi tube exists negative pressure and stays in pipeline and play the antifreeze temperature drop that prevents and form Hydrate Plugging.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
