Description
Technical field
The utility model relates to surveying instrument, particularly a kind of electronic inner float ball fluid level transmitter.
Background technology
Electronic inner float ball fluid level transmitter is applicable to high temperature, high pressure, thickness, dirty medium, pitch, contain the continuous coverage of the liquid level of media such as oil product such as cured and inflammable, explosive, corrosivity.In petrochemical equipment, often be applied to liquid level at the bottom of the fractionation Tata, in the level gauging such as liquid level, efficiently solve high temperature, the problems of measurement of viscous medium at the bottom of the normal pressure Tata.
Electronic inner float ball fluid level transmitter is mainly formed by measuring sensing mechanism and electronic transmitter two large divisions.Measuring sensing element is the ball-shaped ball float.When liquid level in the tower still changes; The corresponding variation takes place in the position of transmitter one-shot measurement element ball float, drives main shaft and rotates, and main shaft is connected with gauge outfit (signalling generator) angular displacement sensor output shaft; Angular displacement sensor converts ball float to corresponding electric signal with the angle variable quantity of liquid level; Again by the inner circuit of gauge outfit with the normalized current signal of this conversion of signals for being directly proportional with level change, teletransmission to instrument pulpit reaches the purpose of remote monitor liquid level.
The ball float that electronic inner float ball fluid level transmitter is in the market provided and the connected mode of club are that internal thread is connected and adds set nut and connect.In actual use because the long-term operation of device; Stirring constantly washing away of steam and processing medium at the bottom of the tower vibrates and high-temperature severe environment; Ball float and club be connected the situation of getting loose that often occurs; Not only can not also have a strong impact on the quiet run of technology for technological operation provides liquid level parameter accurately, operating personnel do not accept and believe the Floating Ball Liquid Level parameter because ball float above-mentioned fault occurs yet during the ordinary production.The instrument maintainer can't carry out on-bne repair to one-shot measurement element in the tower of ball float during the ordinary production.Instrument maintainer is the fault location reason accurately.And in each maintenance, all to send the special messenger that ball float is dismantled as important maintenance content, and carry out the maintenance of pretension screw thread and check work, because the floating-ball fluid level transmitter volume is big, quality is heavy, overhauls time-consuming.
The utility model content
The utility model technical matters to be solved provides a kind of ball float and club is difficult for getting loose, and does not influence the quiet run of technology, the electronic inner float ball fluid level transmitter of saving of work and time.
The utility model is achieved in that a kind of electronic inner float ball fluid level transmitter, comprises ball float, pedestal, club, balance bob, is fixed with support on the said ball float; Said club is about the pedestal left-right symmetric; Said balance bob is located on the club of an opposite side with ball float, and said pedestal is provided with main shaft and angular displacement sensor, and said main shaft is connected with the output shaft of angular displacement sensor; Said club middle part is fixedly connected with said main shaft, and the support on the said ball float is welded on the club.
Further, the external end head of said support has internal thread, and the end that said club is connected with support has the external thread that matches.
Further, adopt the stainless steel electrode welding between support on the said ball float and the club.
The utility model compared with prior art; Beneficial effect is: through on the said club of said electronic inner float ball fluid level transmitter, said pad being set; Make the said support and the said club of said ball float be welded to each other fixing; After putting into operation, the ball float obscission do not occur, the time between overhauls(TBO) was brought up to more than 2 years.Thereby greatly reduce human input and maintenance cost with few input, stopped the generation of above-mentioned one-shot measurement element fault, ensured the accuracy of in-site measurement.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1; Fig. 1 is the structural representation of the electronic inner float ball fluid level transmitter 100 of the utility model; Said electronic inner float ball fluid level transmitter 100 comprises ball float 10, pedestal 40, club 30, balance bob 50, pad 20, welding or the one-body molded support 12 that has external end head to have internal thread on the said ball float 10, and the support 12 on the said ball float 10 is welded on the club 30; Pad 20 as shown in fig. 1
Said club 30 is about pedestal 40 left-right symmetric; Said balance bob 50 is located on the club 30 with ball float 10 opposite sides; Said pedestal 40 is provided with main shaft 42 and angular displacement sensor 44; Said main shaft 42 is connected with the output shaft of angular displacement sensor 44, and said club 30 middle parts are fixedly connected with said main shaft 42, adopts welding or screw thread interlocking.
Principle of work: when the liquid level in the container changes; Under the effect of said ball float 10 and said club 30, drive said main shaft 42 swings, and then drive the output shaft rotation of angular displacement sensor 44; Angular displacement sensor 44 converts ball float 10 to corresponding electric signal with the angle variable quantity of liquid level; Again by the inner circuit of gauge outfit with the normalized current signal of this conversion of signals for being directly proportional with level change, teletransmission to instrument pulpit reaches the purpose of remote monitor liquid level.
The material of one-shot measurement element ball float 10 and support 12 is generally carbon steel or 304, so select for use stainless steel electrode that support 12 and club 30 are welded.Avoid destroying the leakproofness of ball float 10 in the welding process; Welding back ball float 10 counterweights change; According to lever principle ball float 10 counterweighs hammer 50 being carried out mechanical location adjusts; And diagonal displacement sensor 44 carries out adjustment and demarcation again, and it is corresponding to make it angle changing and 4-20mA current transducer output signal, satisfies technological requirement.
In sum; The electronic inner float ball fluid level transmitter of the utility model is through being provided with pad on the club of electronic inner float ball fluid level transmitter; Make the support and the said club of ball float be welded to each other fixing; Thereby make said ball float and said club when long-term work, be difficult for getting loose, and do not influence the quiet run of technology, saving of work and time.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
