Abstract
The present utility model relates to a liquid level controller, especially to a controller matched with a long-distance digital display dual-purpose instrument. The controller matched with the long-distance digital display dual-purpose instrument comprises two relays of an A relay and a B relay, each relay has one to eight contacts, an A1 contact is connected with a B7 contact, an A3 contact is connected with a B3 contact, an A8 contact is connected with a B8 contact, and a B1 contact is connected with a B2 contact. The controller is very simple and can be made only by making some connections between contacts of two miniature relays, the cost price is only about 20 yuan, and full-automatic water-filling procedures can be realized.
Description
Technical field
The utility model relates to a kind of fluid level controller, the supporting controller of especially a kind of and long-range digital display double-purpose instrument.
Background technology
Present control for pot liquid, the general employed float control that is still; Comparatively advanced rod-type magnetic level transmitter, but the environment for use of its incompatibility HTHP are like boiler.Range estimation boiler water level height uses all the time and has only visual glass tube so far, have also need provide illumination, often the blowdown cleaning and can only close-ups etc. many defectives.
Summary of the invention
The purpose of the utility model is, provide a kind of simple in structure, the life-span is long, be adapted at work under the high temperature and high pressure environment with the supporting controller of long-range digital display double-purpose instrument.
The utility model solves the technical scheme that its technical matters adopted: the supporting controller of a kind of and long-range digital display double-purpose instrument; Comprise two relays, be respectively A relay, B relay, each relay has 1～8 eight contact; The A1 contact is connected with the B7 contact; The A3 contact is connected with the B3 contact, and the A8 contact is connected with the B8 contact, and the B1 contact is connected with the B2 contact.
Said structure has designed a kind of extremely simple controllers, and its only needs to do some connections between the contact between two miniature relays, and cost price just surplus in the of 20 yuan, just can realize the full automatic water program that adds.
Description of drawings
Fig. 1 is the synoptic diagram of present embodiment.
Embodiment
Can know that with reference to figure 1 the supporting controller of a kind of and long-range digital display double-purpose instrument comprises two relays; Be respectively A relay, B relay, each relay has 1～8 eight contact, and the A1 contact is connected with the B7 contact; The A2 contact is connected with the external power source live wire, and the A3 contact is connected with the B3 contact, and the A5 contact is connected with external electric pumping source line; The A6 contact is connected with outside electric pump; The A8 contact is connected with the external power source zero line with B8 contact series connection back, and the B1 contact is connected with outside upper limit control line with B2 contact series connection back, and the B6 contact is connected with outside lower limit control line.
Operation: when water tank need add water, A, B relay are not all worked [there are 1. a number electrode and 9. number electrode in the outside], and the electric pump power supply passes through A5, A6; Electric pump work adds water, and (annotate: A5 refers to No. 5 contacts of A relay; Down together) when the completely extremely outside 1. number electrode of water level, though the existing electricity of lower limit control line, B1 does not have; B6, B7 no power, water level continue to rise.
When water level during completely to 9. number electrode; The upper limit control line has the work of electric B relay, and B2, B3, B6, the work of B7 energising A relay are cut off A5 and A6 and stopped to add water; Simultaneously when 9. decline of water table leaves number electrode; A3, A2 switch on when making the outage of upper limit control line, continue to supply A to work by control power firestreak line, make A5, A6 keep off-state.
When water level continues to drop to when 1. number electrode does not have electricity, the lower limit control line does not have electricity, and A2, A3 break off, and the A relay is not worked, and A5, A6 energising add water once more.Go round and begin again like this, control automatically, program is simple, cheap.
