Abstract
The invention discloses a liquid level controller structure of an automatic water-draining device. The invention mainly aims at the situation that a liquid level controller mistakenly judges height of a liquid level in the water inlet process of the publically known automatic water-draining device. An isolation layer is formed on each liquid level sensing terminal of the liquid level controller so that water is prevented from contacting each liquid level sensing terminal in the water inlet process, or mutual conduction among all the liquid level sensing terminals caused by a bridging phenomenon due to the fact that internal water molecules are too dense is prevented. Therefore, mistaken judgment of height of the liquid level by the liquid level controller is avoided, the automatic water-draining device is started under the normal state and thus industrial manufacturing programs proceed smoothly.
Description
Technical field
The present invention relates to a kind of self-draining arrangement, particularly relate to a kind of fluid level controller structure of self-draining arrangement.
Background technology
In many industrial manufacturing process, water is one of indispensable important element, so in many industrial manufacturing equipments, often need a self-draining arrangement is set, the required water yield while providing industry to manufacture, this industry manufacturing course can be carried out smoothly, this self-draining arrangement comprises the water tank that can supply with and store large water gaging, and a fluid level controller that is used for controlling liquid level in water tank, use the water yield guaranteed in water tank in industrial manufacture process, avoid the situation of undersupply.
Consult shown in Fig. 1, the diagrammatic cross-section that shows known self-draining arrangement, this self-draining arrangement comprises a water tank 11 and a fluid level controller 12, wherein this water tank 11 is comprised of a upper cover 111 and a tank body 112, and this upper cover 11 has a water inlet 111a, for external water source, enter in tank body 112, this tank body 112 has the tank 112a of a splendid attire water, and this tank 112a has a water delivering orifice 112b, and install a draining valve 13 in this water delivering orifice 112b, the required water yield when providing industry to manufacture, this fluid level controller 12 comprises the liquid level sensing terminals 121 that two (also can be a plurality of) are arranged in water tank 11 and are arranged to differing heights, 122, and one be equipped with in this water tank 11 and with this liquid level sensing terminals 121 respectively, 122 control modules 123 that are electrically connected, so can be by each liquid level sensing terminals 121, 122 coordinate according to liquid level the specific conductance predicting, reach the effect that liquid level is controlled and whether water is exported.Yet the liquid level sensor of known self-draining arrangement is used situation still to have the defect that need improve immediately in reality:
Due to this liquid level sense side terminal 121, it is exposed without covering state that 122 outside surface is all, therefore, this liquid level sensing terminals 121, any position of 122 contacts with water, all can be sensed by this control module 123, accordingly, water inlet 111a when external water source by these water tank 11 upper covers 111 flows in these water tank 11 internal procedures, once intake pressure is excessive, water can spray and with this liquid level sensing terminals 121, 122 contacts, or make this two liquid levels sensing terminals 121, 122 mutual conduction, and cause the erroneous judgement of height of liquid level, allow this self-draining arrangement start under abnomal condition, cause industrial manufacturing course to carry out smoothly, in addition, water inlet 111a when external water source by these water tank 11 upper covers 111 flows into behind these water tank 11 inside, hydrone once these water tank 11 inner spaces is too dense, hydrone can contact generation " arch formation " between this liquid level sensing terminals 121,122, make 121,122 mutual conduction of this two liquid levels sensing terminals, and cause the erroneous judgement of height of liquid level, namely respectively between this liquid level sensing terminals 121,122, by hydrone, cause to electrically conduct, and cause the erroneous judgement of height of liquid level.
Accordingly, fluid level controller structure how to develop a kind of self-draining arrangement can solve above-mentioned defect, is the motivation of this case invention.
