Abstract
An anti-scaling liquid level switch relates to a liquid level (water level) detecting device for all containers and comprises float balls, magnetic rings, a body, reed switches and stoppers. A circular through hole which runs through vertically is manufactured on each float ball, the magnetic rings are horizontally arranged in the float balls, the body is tubular, the float balls are configured on at least one vertical location of the body, corresponding portions, which are configured with the float balls, of the body are inserted into the through holes of the float balls in an extending manner, the float balls can slidably float up or are slidably sunken along the corresponding portions of the body, the stoppers are respectively clamped at positions above or below the corresponding portions of the body, each float ball is movably positioned within a certain range including a space above the corresponding portion of the body and a space below the corresponding portion of the body, the reed switches are respectively arranged in the corresponding portions of the body, and a teflon layer is manufactured on the outer wall of the body. Scaling can be prevented owning to chemical stability of teflon, and the problem that existing float balls are jammed by scale deposits and an existing liquid level switch is failed is effectively prevented.
Description
Technical field
The utility model relates to liquid level (water level) arrangement for detecting of all containers, refers to especially use usually in the equipment that needs supply water or draining is handled to carry out the good antiscale property level switch of water level control detecting.
Background technology
Level switch is used very wide.Traditional molten stainless steel bit switch mostly adopts the design of stainless pipe body, and the stainless pipe body is stretched the ball float that inserts in a band endoporus, and the built-in magnet ring of ball float is inserted container with detecting molten steel (water level) with ball float and body.This kind structure exists following not enough:
This kind stainless steel water bit switch mostly is applied among the warm water, so after regular meeting is because of fouling on the body rod tube, cause the ball float stuck phenomenon, causes equipment failure to crash, and therefore necessary often cleaning is to keep normally motion smoothly of ball float.
Add the stainless steel water bit switch of Teflon sleeve pipe, this structural design effectively reduces because of incrustation scale and causes the ball float stuck phenomenon.
Summary of the invention
The utility model is intended to overcome the above-mentioned deficiency of prior art, and the good antiscale property level switch is provided.
To achieve these goals, accomplish above-mentioned task, the utility model good antiscale property level switch adopts following technical scheme:
Structure the utility model good antiscale property level switch comprises ball float, magnet ring, body, tongue tube and catch, drives the manhole of system break-through about in the of on the ball float, being built in the ball float of magnet ring level; Body in a tubular form; Body at least one position configuration ball float up and down; Stretch in the said through hole that inserts in ball float at the body position of the correspondence of configuration ball float; And ball float can or slide along this corresponding body position slip come-up, and position difference clamping one catch under reaching on this corresponding body position makes the ball float activity orientation in the certain limit up and down that comprises the body position that this is corresponding; At the built-in tongue tube of the body position of each said correspondence difference; Its eminency is that the outer wall of body is made teflon layer.
Technique scheme is further set forth:
Said tongue tube is electrically connected with lead-in wire, and said lead-in wire is electrically connected with external circuit.
In the configuration of the upper end of body body is installed on by the joint of detecting container, this joint is shaped on external thread.
Said teflon layer is produced on the outer wall of body through spraying.
The working mechanism of the utility model is following:
Ball float and body are inserted container with detecting water level (liquid level), when water level arrives the ball float position of setting, the ball float come-up, magnet makes the conducting of tongue tube loop near the tongue tube induction zone of (claiming dry reed switch again); When water level did not reach the ball float position of setting, ball float sank, and magnet is away from the tongue tube induction zone, and the tongue tube loop is broken off.Body at least one position configuration ball float up and down promptly at body a plurality of position configuration ball floats up and down, can be realized the detecting of a level switch to a plurality of detecting water levels (liquid level) in the same container like this.
The utility model good antiscale property level switch; Compare with prior art; Beneficial effect is: one of which, and the outer wall of body (the whole outer wall that refers to body) is made teflon layer, because the chemical stability of Teflon; Can prevent fouling, effectively prevent to cause the stuck problem that level switch was lost efficacy of ball float because of incrustation scale.Its two, simple in structure, effective.Its three, reduce wash number and time to level switch, practice thrift man-hour.
Description of drawings
Fig. 1 is the utility model synoptic diagram;
Fig. 2 is the utility model decomposing schematic representation.
Among the figure: 1, body; 2, catch; 3, ball float; 4, tongue tube.
Embodiment
Below, introduce the embodiment of the utility model in conjunction with accompanying drawing.
Like Fig. 1-shown in Figure 2, the utility model good antiscale property level switch comprises ball float 3, magnet ring, body 1, tongue tube 4 and catch 2, drives the manhole of system break-through about in the of on the ball float 3, being built in the ball float 3 of magnet ring level; Body 1 in a tubular form; Body at least one position configuration ball float 3 about in the of 1; Stretch in the said through hole that inserts in ball float 3 at the body position of the correspondence of configuration ball float 3; And ball float 3 can or slide along this corresponding body 1 position slip come-up, and position difference clamping one catch 2 under reaching on this corresponding body 1 position makes ball float 3 activity orientation in the certain limit up and down that comprises this corresponding body 1 position; At the built-in tongue tube 4 of body 1 position of each said correspondence difference; Its eminency is that the outer wall of body 1 is made teflon layer.
Said tongue tube 4 is electrically connected with lead-in wire, and said lead-in wire is electrically connected with external circuit.
In the configuration of the upper end of body 1 body 1 is installed on by the joint of detecting container, this joint is shaped on external thread.
Said teflon layer is produced on the outer wall of body 1 through spraying.
The above only is the preferred embodiment of the utility model, is not that the technical scope of the utility model is done any restriction.The technician of the industry; Under the inspiration of present technique scheme; Can make some distortion and revise, every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme above any modification, equivalent variations and modification that embodiment did.
