Description
Technical field
The utility model relates to a kind of linear displacement transducer, particularly relates to a kind of novel linear displacement transducer.
Background technique
At present, pressure regulator valve indicates and valve position signal remote functionality on the spot for realizing valve position scene, needs to install Liang Zu valve position indicating device.One group of machinery valve position scene indicating device on the spot, one group of electronics valve position far-transmission machine structure.Existing pressure regulator valve is used by above-mentioned Liang Zu mechanism simultaneously, wherein one group of mechanical mechanism can testing valve event being valve itself and installing, it is connected with valve inner part, when valve opening or when closing, valve inner piece drives valve position indicating arm to carry out straight line motion, and valve position indicating arm top is provided with on-the-spot indicating piece, and outside is equipped with a graduated scale, read the mobile position data of valve position indicating arm, i.e. the switching position of valve.Other one group is, in valve, same mechanical mechanism is also housed, just valve position indicating arm top connects an electronic line of sight displacement transducer again, drive the motion of linear displacement transducer axostylus axostyle by valve position indicating arm, realize the unlatching of valve or the Signal transmissions of closing motion.Electronic line of sight displacement transducer also needs to be fixed in addition on the adpting flange of pressure regulating valve, complicated structure, and because the reason in valve mechanism space during being connected with between valve position indicating arm and electronic line of sight displacement transducer, also need separately to add transition connecting sheet, there is certain gap, easily lose transmission of signal.
Summary of the invention
In view of this, in order to overcome existing valve position indicating device deficiency structurally, the utility model provides a kind of novel linear displacement transducer, this novel linear displacement transducer can not only observe the unlatching of valve and the location status of cut out, and can realize the transmission of remote signal of valve opening.
For achieving the above object, the utility model adopts following technological scheme:
Valve position indicating device and linear displacement transducer are designed to into integral type, valve position instruction sliding bar is partially embedded into valve inner, remove unlatching and the closing motion of perception valve, during valve opening, the sliding bar of valve inner piece compression novel linear displacement transducer moves downward, when the valve is closed, valve inner piece loses the thrust to sliding bar, and sliding bar moves up under spring force.The spring be furnished with of sliding bar front end can according to the change of valve self aperture, utilizes spring force to make sliding bar do movable according to the track of parts corresponding thereto in valve.Sliding bar lower end is furnished with a resistance slide plate, and sliding bar drives resistance slide plate to move, and changes its resistance value, then is transferred out by resistance signal by output line, complete the function of valve position teletransmission.High-strength magnet in one piece is also studded with below sliding bar resistance slide plate; with the adhesive of outer high-strength magnet; the copper shell of one deck is had outside ring-shaped slide resistance; play the effect of protective resistance; simultaneously also as the slide guide of outer high-strength magnet; when under the drive of interior high-strength magnet at sliding bar during straight line motion; will by the strength of the mutual adhesive of inside and outside two high-strength magnet; outer high-strength magnet is driven to do the Linear Synchronous action identical with interior high-strength magnet; by observing the position of outer high-strength magnet, the enable possition state of valve just can be known.A dust-proof cover is equipped with in the outside of high-strength magnet outside, is carved with stroke mark numerical value above, this makes it possible to the enable possition reading valve accurately.
The utility model beneficial effect is, a device just can realize pressure regulator valve scene indicating status and the signal is far passed function on the spot, avoids the connection error of linear displacement transducer and sliding bar, make scene on the spot indicating status and the signal is far passed more accurate; Reduce a set of original valve position indicating device, both reduced cost of production, and decreased the leakage point of valve itself, and improve the sealability of valve.
