Abstract
The utility model mainly relates to a crucial equipment commutator on the standard device of a detection and correction liquid flow instrument, in particular to a stroke speed and time difference adjustable commutator. The utility model comprises a liquid outlet nozzle (1) and a flow deflector (2). The utility model is characterized in that the flow deflector (2) is provided with a movable guide wheel (6); a horizontal fixing bracket (5) is arranged below the movable guide wheel (6); a pneumatic reversing mechanism (4) is connected with the flow deflector (2). Within the stroke of 100 mm, the commutator can stably move from right to left on the horizontal direction without splashing-leakage and changing of the liquid flow direction; the stroke time difference is adjusted and controlled to be equal to or less than 5 ms through a micro-pressure regulating valve under the condition of equal stroke and equal flow.
Description
Technical field:
The utility model relates generally to the key equipment commutator that detects and calibrate on the liquid flow instrument standard set-up.
Background technology:
Commutator is the key equipment that detects and calibrate on the liquid flow instrument standard set-up.Switch about the operation commutator, with flow of liquid after detected instrument, enter the standard operation measuring device from the nozzle outflow by air deflector, switch with the start and stop counting of tested instrument synchronous about commutator, be commutator commutate left tested table begin the counting, liquid enter the right work measuring instrument, commutator commutate to the right tested table stop the counting, liquid enters the work measuring instrument on the left side.Therefore, the journey time difference Δ T of commutation is the important parameter that directly influences the calibrating indicating instrument precision about.As Fig. 1, at same traffic Qn, under the identical stroke Ln condition, represent that 1. commutator changes to the curve of work measuring instrument, the time from 0 to T
1, 2. represent the swap out curve of work measuring instrument of commutator, the time from 0 to T
2, formation time difference Δ T.Because the existence of Δ T has produced the dash area among Fig. 1, has represented the volumetric flow rate that can't determine, makes the standard set-up precise decreasing, bring error for the calibrated fluxes instrument.Therefore,, dwindle the dash area area, just can improve the standard set-up precision, improve the uncertainty of tested flow instrument by reducing journey time difference Δ T.
Present existing commutator, air deflector is not steady move left and right, but pneumatic reverse mechanism is connected the center of air deflector, it is to swing by air deflector by the operation pneumatic mechanism, reach the purpose of liquid commutation, want to improve the commutation effect of commutator, must strengthen the amplitude of oscillation of air deflector, from and make commutation journey time difference increase, the domestic commutator mistiming all＞20ms, and when commutation, also have vibration and spatter the leakage phenomenon, these factors have all influenced the degree of accuracy of device.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of travel speed and mistiming scalable commutator is provided, and can effectively improve the calibrating indicating instrument precision and can't spatter leakage.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of travel speed and mistiming scalable commutator, include liquid outlet nozzle (1), and air deflector (2), air deflector (2) is provided with mobile idler pulley (6); The below of mobile idler pulley (6) is provided with horizontal fixed support (5), horizontal fixed support (5) requires the machining precision height, must not there be phenomenons such as beating, swing and rock in the integral installation jail, allows the air deflector (2) can be along horizontal fixed support (5) move left and right by mobile idler pulley (6); Pneumatic reverse mechanism (4) is connected with air deflector (2), and pneumatic piston (41) is when being moved to the left, and air deflector (2) is moved to the left the standard operation measuring device that the commutation of liquid stream enters the right thereupon; Pneumatic piston (41) is when moving right, and air deflector (2) the hydrodynamic stream commutation that thereupon moves right enters the standard operation measuring device on the left side.
Described travel speed and mistiming scalable commutator, described pneumatic reverse mechanism (4) are to be provided with minute-pressure modulator (42) on pneumatic cylinder (41).Minute-pressure modulator (42) is provided with two valves, and two valves replace open operation pneumatic piston (41) side-to-side movement, drives air deflector (2) and steadily moves, thereby change the liquid flow path direction; The supply gas pressure of setting and regulation and control pneumatic pistons (41) can be determined the travel speed of commutator; The journey time difference is regulated and control to Δ T≤5ms under identical stroke same traffic by the minute-pressure controlling valve.
Be provided with dividing plate (7) in the middle of described travel speed and the mistiming scalable commutator, described air deflector (2).The water delivering orifice of fixed nozzle (1) and air deflector upper edge hole be smooth, and to cut distance very little, and air deflector (2) steadily moves about on the horizontal fixed support (5), and liquid stream does not take place when commutating the liquid that will flow out from fixed nozzle (1) exchanges and splash.
The beneficial effects of the utility model are: commutator steadily moves about level in the 100mm stroke, does not have to spatter to leak to change the liquid flow path direction; The journey time difference is regulated and control to Δ T≤5ms under identical stroke same traffic by the minute-pressure controlling valve.
