Abstract
The utility model provides a control valve for stabilizing liquid flow, comprising a valve body (10), a valve core assembly (20) disposed in the valve body, along the central axis of the valve body (10), a through hole adapted to the valve core assembly (20) is disposed, one end of the through hole is provided with a liquid inlet (11), the hole wall of the through hole is provided with a liquid outlet (12); the valve core assembly (20) comprises a piston (21) and a piston pull bar (22), the pull bar (22) is operated to make the piston (21) axially move in the valve body (10), so as to make the piston (21) block, partially block or open the liquid outlet (12), thereby controlling liquid flow speed from the liquid inlet (11) to the liquid outlet (12). The control valve is advantaged by simple structure, low cost, and capability of stabilizing and controlling liquid flow via fine adjustment.
Description
Technical field
The utility model relates to liquid distribution, conveying or grass-hopper, particularly relates to the device that liquid quantitative is carried in the commercial production, especially relates to the control valve of stable liquid flow on the production line.
Background technique
Liquid on the existing technology production line in the high position tank directly gets into the metering box, can be excessive because of impacting, and cause metering unstable, and can't accurately regulate and the controlling liquid flow.
The model utility content
The technical problem that the utility model will solve is to avoid the deficiency of above-mentioned existing technology and control valve that a kind of stable liquid flow is provided, and it is simple in structure, and is with low cost, can stablize and the controlling liquid flow through fine adjustments.
The technological scheme that the utility model solve the technical problem proposition is: a kind of control valve of stable liquid flow; Be serially connected on the liquid conducting pipes with the stable liquid flow, comprise valve body and interior mangetic core assembly thereof, especially; Central axis along said valve body; Be provided with and the suitable through hole of said mangetic core assembly, an end of this through hole is a liquid entering hole, on the hole wall of this through hole, is provided with liquid outlet; Said mangetic core assembly coaxial line is packed in the through hole of said valve body, comprises piston and piston pulling rod, and the front end of this pull bar stretches in the said valve body affixed with said piston, and then stretch out outside the said valve body rear end; Handle said pull bar said piston is moved axially in valve body, cause piston is blocked, part is blocked or open wide said liquid outlet, thereby control flow to the flow rate of liquid of said liquid outlet from said liquid entering hole.
Said through hole has circular cross sections; Include said liquid entering hole the front end liquid input section, the middle part fluid section of said liquid outlet is set; With with said pull bar on the rear end linkage section of screw thread position engagement, the diameter of the somewhat larger in diameter of said through hole liquid input section fluid section in the center, the diameter of said piston are slightly less than the diameter of said through hole middle part fluid section; Said piston end face is provided with round gasket, and the diameter of the diameter of sealing pad and said through hole middle part fluid section is suitable.
Said pull bar is cylindric for carefully, on the cylinder of its caudal part, axially is provided with the dial that is used to calculate fluid flow.
The afterbody of said pull bar is provided with regulating handle.
Compare with existing technology, the beneficial effect of the control valve of the utility model stable liquid flow is, through finely tuning this control valve, the flow rate of liquid of valve body liquid outlet is changed, and simultaneously, the dial on the piston pulling rod has shown the distance that piston moves.According to the variation of dial high scale, and flow into the variation of liquid volume in the follow-up flow measurement box, the accurate controllable liquid flow of unit of account scale, thus play the effect of stabilized fluid pressure head.
Description of drawings
Fig. 1 is that the control valve of the utility model stable liquid flow is serially connected in the orthographic projection cross-sectional schematic on the liquid conducting pipes.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
With reference to shown in Figure 1; A kind of control valve of stable liquid flow is serially connected on the liquid conducting pipes with the stable liquid flow, comprises valve body 10 and interior mangetic core assembly 20 thereof; Central axis along said valve body 10; The through hole suitable with said mangetic core assembly 20 is set, and an end of this through hole is a liquid entering hole 11, on the hole wall of this through hole, is provided with liquid outlet 12; Said mangetic core assembly 20 coaxial lines are packed in the through hole of said valve body 10, comprise piston 21 and piston pulling rod 22, and the front end of this pull bar 22 stretches in the said valve body 10 with said piston 21 affixed, and then stretch out outside the said valve body 10 rear end; Handle said pull bar 22 said piston 21 is moved axially in valve body 10, cause piston 21 is blocked, part is blocked or open wide said liquid outlet 12, thereby control flow to the flow rate of liquid of said liquid outlet 12 from said liquid entering hole 11.
Said through hole has circular cross sections; Include said liquid entering hole 11 front end liquid input section 60, the middle part fluid section 70 of said liquid outlet 12 is set; With with said pull bar 22 on the rear end linkage section 80 of screw thread position engagement; The diameter of the somewhat larger in diameter of said through hole liquid input section 60 fluid section 70 in the center; The diameter of said piston 21 is slightly less than the diameter of said through hole middle part fluid section 70, and the end face of said piston 21 is provided with round gasket 30, and the diameter of the diameter of sealing pad 30 and said through hole middle part fluid section is suitable.
Said pull bar 22 is cylindric for carefully, on the cylinder of its caudal part, axially is provided with the dial 40 that is used to calculate fluid flow.
The afterbody of said pull bar 22 is provided with regulating handle 50.Through rotation adjusting handle 50, regulating piston 21 is positioned at the position of liquid outlet 12, and liquid gets into valve body 10 from liquid entering hole 11, and then flows out from liquid outlet 12, gets into follow-up flowmeter metering again.According to dial 40 and the variation of measuring liquid volume in the box, accurately the controllable liquid flow of unit of account scale.
