Abstract
The utility model discloses a liquid source automatic monitoring device. The utility model is characterized in that the lower end of a main body (1) is provided with a liquid source sensor (8) which is arranged in a three-way pipe (9), the upper end of the main body (1) is provided with a rubber tympanic membrane (4) which is provided with an annular permanent magnet (2), and the middle part of the main body (1) is provided with a micro air through hole (5); a cavity which is arranged on the upper part of the main body (1) is communicated with the air in the three-way pipe (9) through the micro air through hole (5), and the top and the middle part of the main body (1) are both provided with tongue reed pipes (1) and (6). The utility model utilizes the changes of the liquid source pressure so that the tongue reed pipes are attracted and switched off through the liquid source sensor (8) and the micro air through hole (5), so a water pump which is connected with the utility model through contacts of a relay works, and a motor of the water pump can not generate free play to waste energy because a water source has no water. The utility model has the advantages of scientific structure, reasonable design and accurate monitoring signal, and the utility model can bring convenience to high or middle-high building users.
Description
Technical field
The utility model is the monitoring device of carrying about liquid, particularly be the aut.eq. that a kind of water pump is monitored water source in the pipeline when drawing water.
Background technology
In the prior art, the water source monitoring device generally is to utilize the performance that water can conduct electricity in the pipeline, make sensitive switch immerse that conducting just can make pump working in the water, although but in the pipeline water is arranged sometimes, and hydraulic pressure is lower, in this case, but is pump water still during pump working, but since sensitive switch be not dipped in the water can't conducting, cause water pump to work; The proportion float formation sensor lighter than water that utilize that also has monitored pipeline water source, after but crisscross water supply line is cut off the water, when supplying water again, because the weight ratio water of air is light, cause float to be in the position of being stopped up by air easily, and cause water pump to work, how to solve and can accurately monitor pipeline water source to make the correct work of water pump be an insoluble all the time difficult problem.
Summary of the invention
In view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of liquid source automated watch-keeping facility that a kind of scientific structure, simplicity of design, pipeline water source are monitored accurate and effective saves energy.For achieving the above object, the utility model is finished as follows: this liquid source automated watch-keeping facility, include body and three-way pipe, the lower end of described body is provided with liquid source sensor, described liquid source sensor places in the three-way pipe, the upper end of described body is provided with the rubber eardrum of annular permanent magnnet, the middle part of described body is provided with the miniature air through hole, the upper end cavity of described body communicates with the air of three-way pipe by the miniature air through hole, the top of described body and the middle part of body are equipped with reed capsule, between described rubber eardrum and bodies top, be provided with back-moving spring, described liquid source sensor is the float that has annular permanent magnnet, and this float can be done spacing activity up and down in three-way pipe.The utility model utilizes the variation of liquid source pressure, make intrinsic reed capsule adhesive and disconnection by liquid source sensor and miniature air through hole, and the relay contact outside this device is controlled the pump motor work that is connected with the utility model, can not make electric pump motor idle running because the water source is anhydrous, waste energy, can not be dipped in the water yet and pump motor is not worked because of sensor, its scientific structure, reasonable in design, the monitoring of liquid source signal accurately, bring great convenience will for resident family's life of high level or middle-high building, bring convenience also will for the monitoring of vast service water and fuel transfer system.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Specific embodiment
Accompanying drawing has been represented structure of the present utility model and embodiment, further describes each relevant details of embodiment below more in conjunction with the accompanying drawings.This liquid source automated watch-keeping facility includes body 3, three-way pipe 9, is provided with liquid source sensor 8 in the lower end of body 3, and described liquid source sensor 8 places in the three-way pipe 9, and the rubber eardrum 4 of band shape permanent magnet 2 is established in the upper end of described body 3.Be provided with miniature air through hole 5 at the middle part of body 3, the upper cavity of body 3 communicates by the air in this micro through-hole 5 and the three-way pipe 9, the top of described body 3 and the middle part of body are equipped with reed capsule 1,6, establish back-moving spring 15 between rubber eardrum 4 and bodies top.Above-mentioned liquid source sensor 8 is the float of band shape permanent magnet 7, and this float 8 can be done spacing activity up and down in three-way pipe 9.During the utility model work, liquid source pressure is just often in the three-way pipe 9, and float 8 is in the come-up state.During float 8 come-ups, annular permanent magnnet 7 on the float 8 is the contact adhesive in the reed capsule 6, make reed capsule 6 be in conducting state, and make the pump motor work that is connected with the utility model, allow water pump can pass through three-way pipe 9 normal pump water by external relay contact.When water supply line was cut off the water, float 8 glided, and reed capsule 6 contacts disconnect, and pump motor is quit work, and can not waste electric energy.If this moment, sensor 8 is stopped up by air, float lost efficacy, have this moment annular permanent magnnet 2 rubber eardrum 4 since the pressure in liquid source upwards push away by miniature air through hole 5, make annular permanent magnnet 2 on the rubber eardrum 4 reed capsule 1 adhesive, make pump motor work, during pump working, the hydraulic pressure of three-way pipe 9 water sucking mouths can descend or be negative pressure state, after back-moving spring 10 resetted rubber eardrum 4, reed capsule 1 contact disconnected, at this moment, delay circuit in the water pump can make pump motor keep one period working time, the air sucking-off in the three-way pipe 9, make float 8 come-ups, after float 8 come-ups, can repeat above-mentioned work again, can't be blocked and make water pump do idle work because of float 8, saved electric energy greatly, also can correctly monitor the signal that the liquid source has or not, compared with prior art, have substantive distinguishing features and progress.
