Abstract
The utility model relates to a sealed automatic controller for water lever, which is used for the water tank which supplies water using differential pressure. The utility model is mainly composed of an air inlet and outlet pipe, a hanger rod, a float cylinder, etc. After the water level contacts the bottom of the float cylinder when water is supplied to the water tank, the float cylinder floats upwards. After the seal pad of the upper surface of the float cylinder seals the outlet of the air inlet and outlet pipe, the water is stopped supplying to the water tank because air can not be expelled. When the water tank drains outwards, the inner part of the water tank is still in a sealed state if draining and water supply are equal. If draining is greater than water supply, the float cylinder falls, and the air enters the water tank from the inlet and outlet pipe. When the water tank stops draining outwards or draining is smaller than water supply, the inner part of the water tank gradually restores the sealed state.
Description
The utility model relates to the water level control that utilizes the pressure reduction water tank, a kind of enclosure-type automatic controller for water level.
The existing method that adopts of the water level of this class water tank control mainly contains two kinds, i.e. lever ball float solenoid valve and lever floater controlled valve, and there is complex structure in these two kinds of operation valves, cost height, problem such as influence water supply during maintenance.
The purpose of this utility model is: for utilizing the water level control of pressure reduction water tank, provide a cover not only novel but also practical enclosure-type automatic controller for water level.
The utility model is finished as follows: when elevated tank when low flush tank supplies water, air is by discharging in the Chang Yuan hole on the air turnover pipe, after the water level contact keg float, keg float begins come-up, after the sealing gasket above the keg float passes in and out the exit seal of pipe with air, because air can not be discharged, so elevated tank just stops to supply water to low flush tank.When the outside draining of needs, if the draining and the bucket etc. that supplies water still are in sealing state in the water tank, if draining is greater than water supply, keg float descends, and air is entered in the case by air turnover pipe, by the time stop outside draining or draining less than water supply, recover sealing state in the water tank gradually.
A kind of enclosure-type automatic controller for water level of the utility model, have simple in structure, maintenance is convenient, do not influence characteristics such as water supply during maintenance, because it is mounted in the peak of water tank, the coupling bolt of the ring seal flange of dismantling during maintenance, keg float just can be taken out from the pipe of garden, at this moment supply water and to do interim control with water supply valve, do not influence water supply when therefore saying maintenance.
Architectural feature below with reference to description of drawings enclosure-type automatic controller for water level:
Fig. 1 is the section of structure of enclosure-type automatic controller for water level.
With reference to Fig. 1, a kind of buoyancy of water that utilizes, make keg float (16) sealing air circulation passage, realize the enclosure-type automatic controller for water level of water level control, it is characterized in that on garden pipe (15) with its welding one be the ring seal flange (12) that several flange screws are arranged on the planar annular of garden, with bolt (13), nut (14) by flange screw with ring seal flange (12) is connected is, form by two garden annulars, on the bigger garden planar annular same flange screw is arranged in the above, the ring seal flange (8) that ring seal wire casing (not shown) is arranged on the baseplane of garden annular below, between ring seal flange (8) and ring seal flange (12), sealing gasket (7) is arranged, cast in block with it on ring seal flange (8) is internal diameter and its identical and concentric Cylinder, symmetry has two Chang Yuan holes on the Cylinder, the threaded air turnover pipe in top (6), the top of air turnover pipe (6) is the nut (3) that the hexagon top center has unthreaded hole with what be threaded, nut (2) is sitting on the center of nut (3), to be threaded from nut (3) unthreaded hole, and air turnover pipe (6), ring seal flange (8), what ring seal flange (12) center was passed is, the Cylinder two ends have threaded top end face center that the suspension rod (4) in studding hole is arranged, suspension rod (4) is by the screw thread of bottom, to be the garden platform for Cylinder is middle up and down, less in the above Cylinder top center has the keg float (16) in studding hole, be suspended in the garden pipe (15) from the top of bottom Cylinder, screw thread with suspension rod (4) bottom, nut (9) passes through packing ring (10) with garden ring-shaped rubber sealing gasket (11), be fixed on the end face of keg float (16) top Cylinder, screw (1) is by the studding hole of suspension rod (4) top center, to cover on air and pass in and out the protective cover (5) that the garden cylindricality top center of managing on (6) has unthreaded hole, be fixed on the top end face of suspension rod (4).
In said structure, garden pipe (15), ring seal flange (12), ring seal flange (8), air turnover pipe (6) and nut (3) etc. constitute housing exterior sealing, the bracing frame of keg float (16) suspention.Nut (2), suspension rod (4), rubber gasket (11) and keg float (16) etc. constitute the inner sealing device.Between keg float (16) and ring seal flange (8), and all leave suitable gap between keg float (16) and the garden pipe (15), constitute air communication channel by above-mentioned gap and air turnover pipe (6).Because the top of suspension rod (4) is limited in the unthreaded hole of nut (3), so all parts in addition that are connected with suspension rod (4), when the enclosure-type automatic controller for water level is worked.All along with keg float (16) is up and down.
Its duty is: when elevated tank when low flush tank supplies water, air is discharged by air communication channel, water level contact keg float (16) afterwards, keg float begins come-up, when the rubber gasket (11) on the end face of keg float (16) top contacts exit seal with air turnover pipe (6) with the baseplane of ring seal flange (8) after, because air communication channel is blocked, air can not be discharged, so elevated tank just stops to supply water to low flush tank, when the outside draining of needs, if draining equates still to be in the water tank sealing state with water supply, if draining is greater than water supply, keg float descends, and air enters in the water tank from air communication channel again, by the time when stopping outside draining or draining, recover sealing state in the water tank again gradually less than water supply.
During installation, garden pipe (15) and tank weld can be inserted weldering, also can be sitting in and giving the upward weldering of boxing out, but no matter adopt the sort of mode to weld, and must guarantee enclosure-type automatic controller for water level vertical and horizontal.
