Abstract
The invention provides an outer-clamping type glass rotameter alarm switch, relates to the field of the glass rotameters and the application of photoelectric technology, and aims to solve the technical problem that currently, largely used glass rotameters do not have flow alarming functions. The adopted technical scheme of the outer-clamping type glass rotameter alarm switch is that reciprocal photoelectric components are clamped on a current glass rotameter; and when flow increases or decreases, and rotor shields reciprocal light beams, flow alarming signals can be sent out. The outer-clamping type glass rotameter alarm switch is characterized in that the switch can be directly mounted on the current glass rotameter for use, without changing any structure or calibration instructions of an original flowmeter.
Description
Technical field
The present invention relates to glass rotameter, particularly glass rotameter is installed additional the flow alarm switch.
Background technology
The glass rotameter of existing band teletransmission function, its structure is: have scale on the tapered glass tube, have rotor in the glass tube, rotor is built-in with magnetic material, fixes the row tongue tube corresponding with flow in the tapered glass tube outside.During work, rotor raises with the increase of fluid flow, and its corresponding tongue tube is held by magnetic material, makes reed switch conduction.Adopt this kind scheme as glass rotors flow alarm switch, have following defective:
1, most of glass rotameter has protective cover, tongue tube is installed need be removed protective cover, uses inconvenient.
2, since glass rotameter be tapered glass tube, flow more greater trochanter from bottom position more away from, more big with the gap of glass tube inwall.Rotor can make corresponding reed switch conduction in the wideer scope when this moves up and down, make alarm range wide, and precision is relatively poor;
3, when actual installation is used, near comprise around the glass rotors liner plate or support are installed can not be with irony or steel material, otherwise produce suction between magnet rotor and the ferrous material, influence the precision of flowmeter;
4, owing to add magnetic material in the rotor, inevitable different with present use of the density of rotor, so physical dimension and the existing rotor that uses also need measure and demarcate during not quite identical, use again.
In sum, adopt magnet rotor install tongue tube make the scheme of glass rotameter alarm switch exist the alarm detection precision not high, use and need demarcate, transform and install relative complex again, be not easy to popularize and promote.
Summary of the invention
The present invention will solve that the alarm detection precision is not high, magnetic float is made and demarcate relative complex, can't be on existing flowmeter by changing that float directly use, be not easy to popularize and problem such as popularization.The present invention is a pair of photoelectric subassembly of clamping on a large amount of glass rotameters that use on the existing market, and the little precision height of beam diameter is installed simple and conveniently, does not do any change to having flowmeter now, is convenient to promote the use of.
Technical scheme of the present invention is: the photoelectric subassembly that installs one group of correlation at glass rotameter additional, when the normal discharge scope is worked, rotor (8) on the glass rotameter (9) can not block photoelectric subassembly to irradiating light beam, when flow raises or reduction, when rotor (8) sheltered from irradiating light beam, photoelectric subassembly sent alerting signal.
External clamping type glass rotameter alarm switch, comprise a photoemission cell (5) and a photoelectric receiving tube (6), be installed in respectively in wild card assembly (1) and the wild card assembly (2), they constitute a kind of photoelectric subassembly of correlation relation, are installed on the glass rotameter (9).Wild card assembly (2) can slide at wild card assembly (1), width between them is to regulate according to the width of flowmeter, can be fixed as one by the screw fixed hole (3) on the wild card assembly (2), can be fit to the glass rotameter of different specification size like this.Front and back positioning screw holes (7) are installed stop screw, can limit the longitudinal separation between glass rotameter (9) and the wild card assembly (1), in order to the rotor (8) in the beam alignment flowmeter of guaranteeing photoelectric subassembly.Utilize the two groups of location top wire holes (4) on the photoelectric subassembly to be fixed on photoelectric subassembly on the glass rotameter (9), and can avoid assembly to rotate.The signal wire of photoelectric subassembly is connected in the electronic circuit, when rotor (8) shelters from irradiating light beam, when photoelectric receiving tube (6) can't receive the light beam that photoemission cell (5) sends, triggers the warning circuit of a band memory and realize reporting to the police automatically.
The present invention compared with prior art has following effect:
1, do not change the original any structure of glass rotameter;
2, do not change the original result of use of glass rotameter and precision;
3, installation is simple and convenient;
4, flow is reported to the police accurately.
Description of drawings
Fig. 1 is structural representation of the present invention
Embodiment
Below in conjunction with description of drawings structure of the present invention and principle of work are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed in protection scope of the present invention.
As shown in Figure 1, external clamping type glass rotameter alarm switch of the present invention mainly comprises photoemission cell (5), photoelectric receiving tube (6), wild card assembly (1), wild card assembly (2), screw fixed hole (3), front and back pilot hole (7), two groups of location top wire hole compositions such as (4).
Photoemission cell (5) and photoelectric receiving tube (6) have welded signal wire respectively, are coated in side and the root of photoemission cell (5) and photoelectric receiving tube (6) with structure glue, insert in the corresponding photoelectricity hole of wild card assembly (1) and wild card assembly (2) the wait adhesive curing.
Wild card assembly (1) and wild card assembly (2) are installed together, make the width between them consistent with the flowmeter width of actual installation, by the screw on the screw fixed hole (3) wild card assembly (1) and wild card assembly (2) are fixed together.
Screw rod before and after regulating on the pilot hole (7) makes photoemission cell (5) and photoelectric receiving tube (6) aim at the center line that moves up and down of rotor (8), guarantees that rotor (8) can shelter from irradiating light beam when moving up and down.
The wild card assembly is moved to the flow scale that needs warning, regulate the jackscrews in two groups of location top wire holes (4), wild card assembly and glass rotameter (9) are fixed together.When the wild card assembly was fixed on the glass tube, the jackscrew front added the cushions.
