Abstract
The utility model discloses a float gas flow meter, which mainly comprises an upper end seat, a lower end seat, a gas quantity adjusting sub-package and a glass sub-package, wherein an inner port of an adjusting core seat in the gas quantity adjusting sub-package is provided with a backstop washer; damping paste is coated on a matching part of an adjusting spindle and the adjusting core seat; the top of the glass tube sub-package is provided with an adjustment positioning seat; and the upper surface of the upper end seat is provided with two levelers in the longitudinal direction and the transverse direction. The float gas flow meter is used for precise adjustment and gas flow metering of a single group or a plurality of groups in automatic instruments and meters, and has the advantages of convenience in mounting and adjustment, accurate metering, reliable work and good use effect.
Description
Technical field
The utility model relates to a kind of instrument and meter suspended body flowmeter, especially for single float gas meter of organizing or organizing minute adjustment and metering more.
Background technology
Suspended body flowmeter is one of parts that are most widely used in the present automation instrument.Along with the development of modern industry, the suspended body flowmeter of the classic method design of using in the instrument and meter of various process control can not adapt to the demand of work.There is following significantly shortcoming in the suspended body flowmeter of classic method design: one, knob and the mandrel of adjust flux do not have disconnecting prevention structure, when the adjust flux meter is in maximum flow, accidentally the manual adjustments mandrel just might be threaded to whole flowmeter and separate, and the feel during adjust flux is not that pine is exactly tight, have not a particle of the damping sense, float is up and down, and wanting to allow flow be positioned at some numerical value is a worrier of taking time; They are two years old, distance between the sealing rubber ring at firm discharge meter scale glass tube two ends is definite value, can not regulate, along with long use, sealing rubber ring loses enough elasticity, flowmeter scale glass tube two ends and sealing rubber ring be not exclusively sealing just, thereby, just can not guarantee the reliable normal operation of flowmeter; Its three, the condition of work of suspended body flowmeter is to guarantee that flowmeter scale glass tube vertically places, otherwise, just can not guarantee the accurate-metering of flowmeter.And in this, traditional suspended body flowmeter has all been ignored, and is difficult to guarantee that glass tube is vertical when installing with use.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art part, and a kind of installation and easy to adjust is provided, the float gas meter of accurate measurement, reliable operation.
The technical solution of the utility model is: a kind of float gas meter, comprise upper end base, lower end seat, regulate packing in the glass tube packing between the upper and lower end seat and the tolerance that is installed on the seat of lower end, described tolerance regulate packing mainly by rotator seat, manual adjustments mandrel, regulate core print seat and knob consists of.Improvements are that the inboard port of adjusting core print seat that described tolerance is regulated in the packing is provided with floor clip, the threaded engagement position of regulating core print seat and manual adjustments mandrel scribbles damping cream, the top of described glass tube packing is provided with the adjusting positioning seat that the upper port with glass tube is sealed and matched, there is the through hole of UNICOM's glass tube endoporus and gas vent this positioning seat inside, and the upper surface of upper end base is provided with two horizon equipments of longitudinal and transverse direction.
Further scheme is: the upper end base of this flowmeter, lower end seat share, and glass tube packing and tolerance are regulated to divide many groups is housed; The two ends of described glass tube are provided with float gear plug and glass tube locating sleeve; Described adjusting positioning seat is positioned at upper end base inside, and threaded engagement between the upper end base, and O-ring seal is arranged; There is scale in the front of described glass tube, and there is yellow coating at the back side.
Good effect of the present utility model is:
1, regulates in the packing in tolerance, designed flowmeter knob (that is manual adjustments mandrel) disconnecting prevention structure, the clearance control of the mating surface of manual adjustments mandrel and adjusting core print seat is at 0.05～0.1mm, and be coated with damping cream at the coaxial rotating face of both relative motions, feel when having solved turn adjust flux knob is not that pine is exactly tight phenomenon, and when the adjusting that increases gas flow since floor clip stop that the manual adjustments mandrel can not come off.
2, there is the adjusting positioning seat that can regulate glass tube butt-end packing degree the upper end of flowmeter scale glass tube, lose certain elasticity at glass tube end face pad, in the time of can not sealing fully, can be screwed down a bit regulating positioning seat, sealing function that just can reinforced gasket guarantees the work reliably and with long-term of whole flowmeter.
3, flowmeter scale glass tube is behind the float of packing into, and the float of having packed at its two ends again gear plug and glass tube locating sleeve like this, can make things convenient for the glass tube assembling of flowmeter, improve assembly precision, prevent that float from tumbling, and do not affect the normal operation of flowmeter.
4, the postnotum of flowmeter, side panel, the surface of upper end base and lower end seat is painted black all, front panel has then adopted colourless poly (methyl methacrylate) plate, particularly (be about whole glass tube cylinder half) painted yellow at the flowmeter scale glass tube back side, thereby, when the analyst reads the flow count value, can be very clear.
5, the horizon equipment of two longitudinal and transverse directions has been installed on the flowmeter upper end base, and glass tube is in plumbness during with the installation of assurance flowmeter and use, guarantees accurate measurement.
