Abstract
The utility model discloses a mechanical liquid control switch, comprising a sleeve pipe. The top part of the sleeve pipe is fixedly provided with a travel switch, and a floating pipe capable of triggering the travel switch is sheathed in the sleeve pipe. The bottom part of the floating pipe is connected with a floating barrel, and the circumference surface of the sleeve pipe is provided with a slot. The floating pipe is provided with a limit pin penetrated in the slot. The product mainly utilizes the mechanical displacement generated by the floating pipe following liquid level fluctuation to trigger the travel switch to send a control signal. When liquid reaches a preset height, the switch acts and sends an electricity turning-on and off signal, sound and light equipment is started to work or conveying equipment is turned on and off to achieve the purpose of alarming and controlling. As the switch device has the characteristics of sensitive and moderate motion, reliable work, convenient overhaul and long using life, the switch device is widely applied to the liquid level control of liquid storage and production process control.
Description
Technical field
The utility model belongs to a kind of control switch, relates in particular to a kind of mechanical type liquid control switch.
Background technology
At present, the production scene fluid storage usually adopts the liquid level gauge of various demonstrations (or indication) liquid position: as glass tube, glass plate type liquid level gauge, ball float slide sign formula liquid level gauge, magnetic turning column liquid level meter or the like.But the demonstration of this liquid level (or indication) is the cooperation by people's sight as a rule to play a role, and has tangible limitation, and it can only not bring into play any effect to the situation that surpasses the liquid level permission in the scope work of permission.So people adopt electronic sensor as near switch super level condition being controlled, liquid property that can be different causes certain difficulty to the type selecting and the reliability of transducer, failure-frequency height not only, and useful life is also undesirable, and cost is difficult to accept sometimes.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, mechanical type liquid control switch that reliability is high.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of mechanical type liquid control switch, it comprises sleeve pipe, described sleeve pipe top is installed with travel switch, be socketed with the floating pipe that can trigger travel switch in the described sleeve pipe, floating pipe bottom is connected with keg float, have bar hole on the described sleeve pipe periphery, described floating pipe is provided with the spacer pin that is installed in the bar hole;
As improvement of the technical scheme, described sleeve pipe middle part is installed with the coupling flange that is connected with equipment;
As further improvement in the technical proposal, by clamping auricle travel switch is connected and fixed on the described sleeve pipe;
Further, described sleeve pipe top is provided with the travel switch protective cover;
Further, the top of described keg float is provided with cushion pad.
The beneficial effects of the utility model are: this product mainly is the mechanical displacement that utilizes floating pipe to produce with the liquid level fluctuation, trigger travel switch and send control signal, when liquid reaches preset height, switch moves thereupon, send the power on/off signal, start the acousto-optic equipment work, perhaps the open and close conveying equipment is warned and the purpose of controlling to reach.Because this switching device has movement sensitive, soft, reliable operation, convenient, the long service life of maintenance, thereby can be widely used in the production technology utilization of the liquid level control of fluid storage and liquid level signal.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of mechanical type liquid control switch, it comprises sleeve pipe 1, described sleeve pipe 1 top is installed with travel switch 3, during installation, by the auricle that clamps on the sleeve pipe 1 travel switch 3 is connected and fixed; In addition, be not subjected to external influence in order to protect travel switch 3, described sleeve pipe 1 top is provided with travel switch protective cover 5.Be socketed with the floating pipe 2 that can trigger travel switch 3 in the described sleeve pipe 1, floating pipe 2 bottoms are connected with keg float 6, have bar hole 11 on described sleeve pipe 1 periphery, described floating pipe 2 is provided with the spacer pin 21 that is installed in the bar hole 11, and the use of bar hole 11 and spacer pin 21 has effectively limited the axial and circumferential motion of floating pipe 2.
This product is for the ease of being installed in it on equipment, and described sleeve pipe 1 middle part is installed with the coupling flange 4 that is connected with equipment.During installation, floating pipe 2 bottom slave unit interface short tubes 7 are inserted device interiors, sleeve pipe adpting flange 4 is fixed on the vessel flange,, move up and down sleeve pipe 1 and position and get final product according to control liquid level height.Certainly; according to actual needs, its mounting means also is not limited to above-mentioned technical scheme, also can adopt other common mechanical structures to substitute; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model in a word.
The utility model is in order to prevent floating pipe 2 in the process of mechanical displacement, and keg float 6 rigid collision takes place and damage product with sleeve pipe 1, and the top of described keg float 6 is provided with cushion pad 8.
This product mainly is the mechanical displacement that utilizes floating pipe 2 to produce with the liquid level fluctuation, trigger travel switch 3 and send control signal, when liquid reaches preset height, switch moves thereupon, send the power on/off signal, start the acousto-optic equipment work, perhaps the open and close conveying equipment is warned and the purpose of controlling to reach.Because this switching device has movement sensitive, soft, reliable operation, convenient, the long service life of maintenance, thereby be widely used in the liquid level control and controlling of production process of fluid storage.
