Abstract
The utility model relates to an adjustable buoy type liquid level gauge with electric contacts, which is characterized in that a buoy structure and an adjustment structure are arranged in a casing, and one end surface of the casing is provided with an inspection window. When the utility model is used, the indicating contacts of an upper limit and a lower limit can be arbitrarily adjusted within detection range, and the height of liquid level can be directly observed by eyes. In addition, the utility model has the advantages of reasonable structural design and low cost and is suitable for measuring the liquid level of equipment under the state of normal pressure in various environments.
Description
The utility model belongs to the measurement class technology of GO1F liquid level, particularly relates to the adjustable float type liquid level gauge of a kind of electric contact.
In the known technology, since equipment need level gauging generally employed " tongue tube float type level gauge ", this kind device is to utilize the tongue tube that is set in advance in the floater guiding pipe, when float fluctuates, make the tongue tube adhesive by the magnet ring that is contained on the float, send contact point signal, reach the purpose of level gauging.But this kind device also comes with some shortcomings when level gauging, and first tongue tube is after setting, and the indication contact can not be adjusted in sensing range, can only show and controls by predefined liquid level position; It two is to adopt this structure can not directly observe out the height of liquid level with eyes; Its three be tongue tube itself is easily broken in vibration environment, influence measuring ability.
The purpose of this utility model is to overcome the deficiency of known technology and provides a kind of contact of indicating in sensing range can adjust arbitrarily, can go out liquid level and be applicable to the adjustable float type liquid level gauge of all-environment novel electric contact with the eyes Direct observation.
The purpose of this utility model is achieved in that
(1) end face of housing is equipped with the structure of view window and is, covers the display piece of selecting transparent material for use is housed by being fixedly mounted on view window on the housing.(2) concrete structure of buoy structure that is equipped with in the housing and adjustment structure is, 3 carrying bolts that all insulate with housing and all have blind hole are housed in the housing lower end, the corresponding position of the blind hole that has with its lower end respectively in housing upper end also is equipped with 3 all with the housing insulation but all have the carrying bolts of through hole, in housing by the adjusting leading screw that has upper limit indication contact and lower limit indication contact is installed respectively between two pairs of wherein corresponding carrying bolts of housing upper/lower terminal; Between the remaining corresponding a pair of carrying bolt buoy support bar that has buoy is installed, above-described adjusting leading screw and buoy support bar all stretch out the carrying bolt of housing upper end, after their external part all is equipped with holddown spring, fixedly mount setting nut again.(3) have vent port in the housing upper end.
The advantage that the utlity model has shows that owing to have buoy and adjustment structure, in use upper and lower limit indication contact can be adjusted arbitrarily in its sensing range.Bring great convenience to the user like this; Again because the view window of selecting for use transparent material to make also can directly be observed out liquid level with eyes.In addition, reasonable in design own, cost is low, and is applicable to the measurement that is used for liquid level on the equipment under the atmospheric pressure state in the various environment.
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of view window of the present utility model;
Fig. 2 is a perspective view of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The view window that has the display piece 3 of transparent material by housing 1 fixed installation covers 2, the material selection organic glass of present embodiment display piece.Be equipped with 3 in the upper end of housing with the housing insulation and all have the carrying bolt 11 of through hole; Corresponding housing lower end also is equipped with 3 with housing insulation but all have the carrying bolt 5 of blind hole.In housing, by between above-described two pairs of wherein corresponding carrying bolts the adjusting leading screw 6 that has upper limit indication contact 10 and lower limit indication contact 4 being installed respectively; Between the remaining corresponding a pair of carrying bolt buoy support bar 9 that has buoy 8 is installed.In addition, regulate the carrying bolt 11 that leading screw and buoy support bar all stretch out the housing upper end, after its external part all is equipped with the deflation spring 12 that has lead 15, fixedly mount setting nut 14 again, by the turn setting nut, upper limit indication contact and lower limit indication contact are moved with the rotation of regulating leading screw is upper and lower, reach the adjustable purpose of contact.Moreover, also have vent port 13 in the housing upper end, be in order to be communicated with atmosphere, so that the utility model remains under the atmospheric pressure state.
According to the different needs that is used for the equipment level gauging, can select single assembly of the present utility model for use, also can select for use the multiple arrangement combination to use.When being used for the level gauging of equipment, on the connecting hole that only needs to have in advance on the communicating pipe 7 that will be equipped with in the utility model and the equipment is fixedlyed connected for single assembly.Equally, when multiple arrangement is used for the level gauging of equipment, can not be subjected to the restriction of liquid level, after only each communicating pipe of the present utility model need being connected in series, just can with equipment is fixing again.
Principle of work of the present utility model is, is connected with infusion pump control circuit on the equipment by the lead in the utility model 15, can control the startup of infusion pump automatically and stops, and the liquid level of carrying out upper and lower bound simultaneously shows, reports to the police.Prescribe a time limit when liquid level is in down, buoy and lower limit indication contact are connected, and have also connected the control circuit of infusion pump this moment, just can carry out the lower limit indication and report to the police, when liquid level raises, move on the buoy and throw off lower limit indication contact, then the lower limit indication is reported to the police and is eliminated, and infusion pump still works on.Prescribe a time limit when liquid level rises to, buoy is connected with upper limit indication contact again, and the control circuit of infusion pump disconnects and quits work, and connects upper limit indication contact circuit simultaneously.When liquid level descends once more, connect lower limit indication contact, repeat above-mentioned course of action.
