Description
Technical field
The utility model relates to controller for liquid flow technical field.
Background technology
At present, in the production run of some operating mode enterprises, need to there is the injection of fluid flow, as industries such as smelting, chemical industry, oil exploitations, in the process of the injection of fluid flow, need to be according to certain technological requirement, as the technical requirement of constant rate water filling, the mode of traditional control flow is to rely on the size of manual shift valve to control flow, and labour intensity is large, and precision is not high.Particularly, under the environment of high pressure, as the high pressure water injection in oil exploitation process, water injection time is long, pressure is high, manual adjustments valve, not only easily causes valves leakage frequently, shortens the serviceable life of valve, and there are many potential safety hazards, threaten operating personnel's life security.In addition, all there are many weak points in existing pipeline flow control valve, as highly pressurised liquid fluid after valve regulated can produce turbulent phenomenon, and build-up of pressure fluctuation, and because pressure differential is large, the adjusting resistance of valve is large.
Utility model content
Technical problem to be solved in the utility model, is the technical deficiency for above-mentioned existence, and a kind of liquid constant-flow control device is provided, the liquid that this device utilizes external pressure to control a sealing container bottom keeps constant pressure, delicate structure, controls simply, has reduced workman's labour intensity.
The technical solution adopted in the utility model is: a kind of liquid constant-flow control device is provided, comprises airtight container, described airtight container top is provided with the threaded control tube of axial zone; Described control tube lower end is positioned at the bottom of airtight container cavity, and the top of control tube is connected by thread seal with airtight container; The upper end of described control tube is positioned at sealed container outside, and is fixed with runner; The bottom of described airtight container is communicated with liquid valve, and the top of airtight container is communicated with liquid feed valve.
Different from traditional opened type container, the utility model adopts airtight container, by control tube and extraneous conducting.When liquid valve is opened, air enters airtight container from control tube lower ending opening, then owing to being subject to buoyancy to rise to airtight container top, control tube lower ending opening to the liquid height between the liquid valve of airtight container remains unchanged, thereby the liquid pressure at liquid valve place is constant.Set after the open amount and the length of control tube in airtight container of liquid valve, liquid will keep constant current state, no longer needs manual control, has reduced workman's labour intensity.
Further optimize the technical program, the airtight container top of liquid constant-flow control device is communicated with normally closed type gas admittance valve.
Due to work requirements (such as clearing up airtight container etc.), liquid in airtight container is rapid when emptying, can be by normally closed type inlet open, air enters sealed container interior from normally closed type gas admittance valve, the control of the uncontrolled pipe insertion depth of liquid pressure at liquid valve place, can increase aquifer yield, rapidly the liquid in airtight container be discharged.
Further optimize the technical program, the sealed container outside of liquid constant-flow control device is provided with the transparent liquid level tube at communication seals container bottom and top.
The beneficial effects of the utility model are: while adopting liquid constant-flow control device, as long as adopt the airtight container of differing heights according to different demands, and set the control tube insertion degree of depth of airtight container and the open amount of liquid valve, the liquid of constant rate just can be provided; When due to work requirements (such as cleaning airtight container etc.), liquid in airtight container is rapid when emptying, can be by normally closed type inlet open, air enters sealed container interior from normally closed type gas admittance valve, the control of the uncontrolled pipe insertion depth of liquid pressure at liquid valve place, can increase aquifer yield, rapidly the liquid in airtight container be discharged; By transparent liquid level tube, can observe the height of liquid level in sealed container, when the liquid in airtight container is down to the liquid level at place, control tube lower end, when closing liquid valve, open normally closed type gas admittance valve, extraneous liquid just can be filled with airtight container again by liquid feed valve.The delicate structure of whole liquid constant-flow control device, controls simply, has reduced workman's labour intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation after Fig. 1 complete section.
In figure, 1 airtight container, 2 screw threads, 3 control tubes, 4 runners, 5 liquid valves, 6 liquid feed valves, 7 normally closed type gas admittance valves, 8 transparent liquid level tubes.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, Fig. 2, liquid constant-flow control device, comprises airtight container 1, and described airtight container 1 top is provided with the control tube 3 that is axially threaded 2; The lower end of described control tube 3 is positioned at the bottom of airtight container 1 cavity, and the top of control tube 3 and airtight container 1 are tightly connected by screw thread 2; The upper end of described control tube 3 is positioned at airtight container 1 outside, and is fixed with runner 4; The bottom of described airtight container 1 is communicated with liquid valve 5, and the top of airtight container 1 is communicated with liquid feed valve 6; Described airtight container 1 top is communicated with normally closed type gas admittance valve 7; Described airtight container 1 outside is provided with the transparent liquid level tube 8 at communication seals container 1 bottom and top.
Different from traditional opened type container, the present embodiment adopts airtight container 1 by control tube 3 and outside conducting.Rotating wheel 4 can regulate control tube 3 to insert the degree of depth of airtight container 1.It is worth mentioning that, during control tube 3 rotation, can remain sealing state (can adopt and seal with wax or oil sealing) by screw thread 2 and airtight container 1 upper end.When liquid valve 5 is opened, air enters airtight container 1 from control tube 3 lower ending openings, then because being subject to buoyancy, air rises to airtight container 1 top, control tube 3 lower ending openings to the liquid height between the liquid valve 5 of airtight container 1 remains unchanged, thereby the liquid pressure at liquid valve 5 places is constant, the flow of liquid is only relevant with the control tube 3 insertion degree of depth of airtight container 1 and the open amount of liquid valve 5, and irrelevant with the residual liquid quantity in airtight container 1.Set after the open amount and the length of control tube 3 in airtight container 1 of liquid valve 5, liquid will keep constant current state, no longer needs manual control, has reduced workman's labour intensity.
When needs provide larger fluid flow, can adopt the mode to control tube 3 pressurizations, improve the pressure of liquid valve 6 place's liquid.
When due to work requirements (such as cleaning airtight container 1 etc.), liquid in airtight container 1 is rapid when emptying, normally closed type gas admittance valve 7 can be opened, air enters airtight container 1 inside from normally closed type gas admittance valve 7, the control of uncontrolled pipe 3 insertion depths of liquid pressure at liquid valve 5 places, can increase aquifer yield, rapidly the liquid in airtight container 1 be discharged; Utilize law of connected vessels, by transparent liquid level tube 8, can observe the height of airtight container 1 interior liquid level, when the liquid in airtight container 1 is down to the liquid level at control tube 3 places, lower end, when closing liquid valve 5, open normally closed type gas admittance valve 7, extraneous liquid just can be filled with airtight container 1 again by liquid feed valve 6.The delicate structure of whole liquid constant-flow control device, controls simply, has reduced workman's labour intensity.
