Abstract
The utility model relates to the field of electric appliance automatic control instruments and particularly relates to a mechanical type liquid level control system. The adopted technical scheme of a ball float-type liquid level controller is that the ball float-type liquid level controller comprises a microswitch, a stay rope, a contact, a side wall, a spring, a stiff rod and a float; the stay rope is connected to a lower part of the microswitch; the spring is arranged between the microswitch and the contact; a hinge is arranged under the contact; the other end of the stay rope is connected with the float; and the stiff rod is arranged between the float and the microswitch. The ball float-type liquid level controller is simple in structure, safe and reliable, is used for accurate liquid level acquisition, and is high is acquisition sensitivity.
Description
Technical field
The utility model relates to electrical equipment instrument for automatic control field, specifically a kind of mechanical type tank level control system.
Background technology
The instrument of automatic control motor pump or electric emblem valve has three kinds at present: transistor type, dry-reed, float mechanical type.Wherein the float mechanical type is not subjected to the influence of the conductive magneto-conductive character of temperature, level control (LC) amplitude and medium, thereby has characteristics such as reliable and stable long service life.Yet practical at present float mechanical type control moves, and does not still break away from from the upper and lower limit bit switch, to relay, to spot power starter, to the chess formula of executive component (electric-motor pump, electric young valve), so still dislike more complicated.
The utility model content
The utility model provides a kind of simple in structure, safe and reliable float-type liquid level controller, is used for providing liquid level is accurately gathered, and gathers highly sensitive.
A kind of float-type liquid level controller, the technical scheme that adopts is: comprise microswitch, stay cord, contact, sidewall, spring, stiff rod and float, the below of described microswitch connects described stay cord, described spring is set between described microswitch and contact, hinge is set below described contact, an other end of described stay cord connects described float, connects described stiff rod between described float and microswitch.
When water pump pumps into water tank when giving take the altitude (upper limit) with water, water is to the buoyancy of float, by the leverage of stiff rod and hinge, change direction and amplification, pulling microswitch contact contact is connected microswitch, and keep this state, thereby stop pump working.
When cistern water level dropped to predetermined lower limit, float descended with liquid level, and microswitch rises under the support of spring, and the pulling microswitch breaks away from the contact, and microswitch is disconnected.Thereby finish the automatic control to electric-motor pump.
More than narration is the water supply state of a control, and the utility model also can be used on the drainage arrangement.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model float-type liquid level controller;
Accompanying drawing 2 is the utility model float-type liquid level controller structural representations under another state.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model, the similar elements label represents similar elements in the accompanying drawing.As mentioned above, the utility model provides a kind of float-type liquid level controller, makes its simple in structure and easy operating and use more.
Shown in accompanying drawing 1,2, a kind of float-type liquid level controller, the technical scheme that adopts is: comprise microswitch 1, stay cord 4, contact 8, sidewall 3, spring 2, stiff rod 6 and float 7, the below of described microswitch 1 connects described stay cord 4, between described microswitch 1 and contact 8, described spring is set, hinge 5 is set below described contact 3, and an other end of described stay cord 4 connects described float 7, connects described stiff rod 6 between described float 7 and microswitch 1.
See Fig. 1, when water pump pumps into water tank when giving take the altitude (upper limit) with water, water is to the buoyancy of float 7, by the leverage of stiff rod 6 with hinge 5, change direction and amplify pulling microswitch 1 contact contact 8, make microswitch 1 conducting, and keep this state, thereby stop pump working.
See Fig. 2, when cistern water level dropped to predetermined lower limit, float 7 descended with liquid level, and microswitch 1 rises under the support of spring 2, and microswitch 1 breaks away from contact 8, and microswitch 1 is disconnected.Thereby finish the automatic control to electric-motor pump.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
Claims (1)
1. float-type liquid level controller, it is characterized in that composed as follows: comprise microswitch, stay cord, contact, sidewall, spring, stiff rod and float, the below of described microswitch connects described stay cord, described spring is set between described microswitch and contact, hinge is set below described contact, an other end of described stay cord connects described float, connects described stiff rod between described float and microswitch.
