The magnetic steel penetrates an upper and a lower reed switch signal transmitting devices in the electric appliance chamber. The purpose of the utility model is achieved through the principle of electromechanical conversion, and the pipeline liquid level signal device has the advantages of high reliability, high safety, good sealing structure, convenient replacement of wearing parts, etc.
Description
The utility model relates in the control of a kind of industrial process and detects and control the pick-up unit that various process pipes have no liquid, particularly a kind of pipeline liquid level signal device that utilizes liquid level in the ball float induction pipe.
At present, what known pipeline liquid level signal device generally adopted is ultrasound wave pipeline fluid level announciator, and it mainly is to be made of ultrasonic probe and circuit part.The flow of liquid mistake is arranged in pipeline, and the ultrasonic probe in the pipeline contact with medium in the pipeline, and probe makes closing of circuit, the output contact signal, and during no liquid, popping one's head in is in off-state, makes the circuit disconnection, blackout.But, because liquid fluidised form complexity in pipeline, especially when non-full pipe, the liquid flow undulate seemingly touches non-touching between probe and the liquid level, cause output signal interrupted, influence control loop, after the evacuation of liquid, because factors such as cleanliness factors, dropping liquid is often arranged attached on the probe, cause spurious signal; The check point position is non-adjustable.These defectives are ubiquity in conventional pipeline liquid level signal device.
The purpose of this utility model is in order to overcome the defective of prior art, Level Detection partly to be improved, a kind of pipeline liquid level signal device is provided, can detecting having or not of pipeline liquid level continuously reliably.
The purpose of this utility model is mainly to realize by the following stated device:
1. pipeline liquid level signal device, comprise test section and circuit part, the test section comprises the liquid inlet, liquid outlet is characterized in that having surge chamber between liquid outlet and inlet, is provided with the electric apparatus room of isolating with surge chamber above surge chamber, be provided with ball float in the surge chamber, the connecting link that is connected with ball float is through between surge chamber and the electric apparatus room, and the upper end of connecting link is fixed with magnet steel, and magnet steel passes two the tongue tube signalling generators up and down in the electric apparatus room.
2. preceding paragraph 1 described pipeline liquid level signal device is characterized in that being isolated by upper end and surge chamber in the surge chamber, and the cylinder that lower ending opening is communicated with surge chamber forms sensing chamber, and ball float places the sensing chamber that forms in the cylinder.
3. preceding paragraph 1 described pipeline liquid level signal device is characterized in that having in the electric apparatus room lower ending opening and is communicated with surge chamber, and the communicating pipe of upper end closed, connecting link and magnet steel placed in communicating pipe, and two tongue tube signalling generators were set respectively up and down outside communicating pipe.
4. preceding paragraph 1 described pipeline liquid level signal device is characterized in that the side of electric apparatus room is provided with visor and scale, and the tongue tube signalling generator connects with cue mark respectively, by the upper-lower position of screw rod aignment mark.
5. preceding paragraph 1 described pipeline liquid level signal device is characterized in that the described top that forms the cylinder of sensing chamber is evenly distributed with some apertures, and there is a baffle plate at the lower ending opening place.
6. preceding paragraph 1 described pipeline liquid level signal device is characterized in that the liquid outlet inlet is provided with ring flange, and surge chamber also is connected by ring flange with electric apparatus room.
Because the utility model has adopted above structure, utilize the principle of dynamo-electric conversion, signalling contact does not directly contact with medium, so the utlity model has very high reliability and security.In addition, it is good also to have a hermetically-sealed construction, and consumable accessory is changed advantages such as convenient, can be widely used in the difform process liquid pipeline of different latus rectums and inflammable, and is explosive, strong acid, places such as highly basic.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the sectional plane figure according to the pipeline liquid level signal device that the utility model proposes.
Circuit part of the present utility model is identical with prior art, different mainly be in the test section.Among the embodiment of the present utility model as shown in Figure 1, has shell 1, level 180 degree directions are welded a pair of flange short tube 2, and 2 one of 3, two flange short tubes of top welding flange are that one of liquid inlet is liquid outlet, form surge chamber A between liquid inlet and the outlet, the cylinder 5 of a lower ending opening is set among the surge chamber A, upper end and ring flange 4 welding, the upper end of cylinder 5 is distributed with some apertures 20, there is a baffle plate 6 at its lower ending opening place, and ball float 7 places cylinder 5.Ring flange 4 is connected with case 8, forms electric apparatus room C, and ring flange 3,4 is connected by bolt, forms two spaces that are isolated from each other.Side on the case 8 is provided with visor 9, scale 10, and line bank 11, inlet wire mouth 12, the communicating pipe 13 that a upper end closed lower ending opening is arranged in case 8 and weld with flange 4, have magnet steel 14 on the connecting link, constitute one with connecting link and ball float.Interconnecting piping is two tongue tube signalling generators 15 up and down, connect cue mark 16 respectively, and adjustable about in the of 17 by adjusting screw(rod).
Liquid enters surge chamber A along the direction of arrow during work, and the space by baffle plate 6 both sides enters the B of sensing chamber, ball float 7 in the sensing chamber upwards floats under the buoyancy of liquid effect, drive connecting link and magnet steel 14 simultaneously with moving on the liquid level, when arriving the precalculated position, magnet steel 14 is with two tongue tube signalling generators 15 of adhesive, thereby the generation liquid level signal is exported to circuit part.
The B of sensing chamber that surge chamber A and cylinder 5 forms is in order to reduce the interference to ball float of liquid flow produced in the pipeline resistance.Make liquid in the sensing chamber can only go up next and move, and then make ball float 7 can compare the situation of the reflection liquid level of exactly.
Flange connects the effect that can finely reach sealing, guarantees not leaked of the interior liquid of pipeline, particularly some danger medium.Communicating pipe 13 had both been isolated electric apparatus room and sensing chamber, can guide magnet steel 14 to move along communicating pipe simultaneously.
The utility model is a ball float with contacting of medium, by the mechanical motion of ball float owing to utilize ball float to detect liquid level, make the tongue tube induction produce electric signal, therefore, pipeline liquid level signal device of the present utility model goes for different media, particularly some corrosive liquids etc.In addition, mark position can be adjusted by screw rod 17, and this is that ultrasonic detection device institute is inaccessiable.
The detailed description of above-mentioned present embodiment just illustrates an instantiation of the present utility model, rather than to qualification of the present utility model, and those skilled in the art can do various changes under the prerequisite of the technical scheme that does not exceed claim and limited.
