Abstract
The utility model relates to an adjusting device for liquid drop amount, which is used for measuring the dropping speed of various liquids. A drum wheel (3) with a scale or an indicating needle (8) is installed on a rotatable valve stem (2), and indication reticles or a scale is processed on a fixed valve body. The utility model is simple, capable of quantifying and reading and free from the environmental influence.
Description
The utility model is a kind of fluid drips quantity regulating device of measuring various liquid droping speeds that is applicable to.
The fluid drips quantity regulating device of present domestic use does not all have the scale indication, measure liquid droping speed and can only use the artificial visually examine, and need repeatedly to adjust just can reach to give fixed requirement, this device exists the adjustment time long, labor strength is big, defective such as easily make mistakes.The fast variable valve that drips that does not have the liquid delivery line among the patent CN86203810.3 also is not have the scale indication, though the speed of dripping that it and photoelectric sensor and the digital photoelectricity liquid droping speed measuring instrument that adopts digital indicator three parts of pulse width modulated shaping circuit to form can measure various liquid accurately, easily, but be applied in the thermal treatment, because the influence of the high corrosion of the high temperature of heat treatment department (salt steam, water vapour) environment, sensor in the instrument, integrated package, circuit corrode more serious, have influenced and have applied.
The purpose of this utility model is that design is a kind of not affected by environment, and it is fairly simple that the amount of dripping is adjusted, and the fluid drips quantity regulating device of energy quantification.
The new liquid of design drips quantity regulating device to be made up of adjusting knob (1), regulating valve stem (2), valve body (4), (9), inlet (5), liquid outlet (6), the drum (3) of a band rule has been installed on its rotating regulating valve stem (2), on the valve body that does not rotate (4), processed the indication groove, also can go up the processing rule at valve body (9), going up an installation pointer (8) at regulating valve stem (2), is a kind of regulating device of reading but make a quantity regulating device.
Accompanying drawing 1 is novel fluid drips quantity regulating device
A figure is the fluid drips quantity regulating device that has the rule drum on the valve rod
B figure is the fluid drips quantity regulating device that has rule on the valve body
(1) is adjusting knob; (2) be regulating valve stem; (3) for being with the drum of rule; (4) for being with the valve body of scale mark; (5) be inlet; (6) be liquid outlet; (7) adjust screw zero point for locating; (8) be pointer; (9) for being with the valve body of rule;
Two kinds of fluid drips quantity regulating devices in the accompanying drawing 1 are to be used for instiling the fluid drips measuring device of formula thermal treatment.It is adjusted screw (7) with the location and will be installed on the regulating valve stem (2) with the drum (3) or the pointer (8) of rule zero point.Drum (3) or pointer (8) rotate thereupon when rotating adjusting knob (1), by the threaded connection relation between regulating valve stem (2) and valve body (4) or (9) regulating valve stem (2) is risen simultaneously, and make the cone-shaped sealing ring of valve rod (2) tip the slit occur, liquid can flow out from the slit, since the scale indicated value with drip the corresponding relation of existence between the speed, at this moment drum (3) or the pointer (8) that rotates with regulating valve stem (2) will indicate corresponding reading on rule.
Because the employed class of liquids of fluid drips quantity regulating device is different, and the surface tension of different liquid is different, there is inevitable difference in the liquid outlet position processing of adding variable valve, so the groove indicated value can not direct representation be dripped the reading of speed, and can only be one mutually on duty.But because this drop regulating device is the fluid drips quantity regulating device that does not have delivery line, the speed of dripping from liquid outlet is comparatively stable, and each scale indicated value measurement error has only 1～2, so value of the correspondence that each scale indicated value can both be more stable.Thereby can adjust the fluid drips amount more conveniently, make and drip amount adjustment work easy, quantification, because the fluid drips quantity regulating device is to be made by stainless steel, environmental impact is little again.
Claims (1)
1, a kind of fluid drips quantity regulating device of mainly forming by adjusting knob, regulating valve stem, valve body, inlet, liquid outlet, it is characterized in that, the drum (3) of a band rule has been installed on rotating regulating valve stem (2), on the valve body that does not rotate (4), has been processed the indication groove; Or, go up an installation pointer (8) at regulating valve stem (2) at the last processing of valve body (9) rule.
