Abstract
The utility model relates to a valve, in particular to an automatic water shutting valve. The automatic water shutting valve comprises a valve body provided with a total water inlet pipe and a water outlet which is communicated with a total water outlet pipe via a water channel. A valve cavity is formed between a gland and the valve body, and the valve cavity is divided to two portions of an upper valve cavity and a lower valve cavity by an elastic rubber plate. The upper end of the water stop pipe in the upper valve cavity is connected with the water outlet of the valve body via the water channel. The lower port of the water stop pipe is positioned over the elastic rubber plate whose outer ring is provided with a small hole communicated with the lower valve cavity. A barrier chip is arranged between the through hole of the center of the gland and the lower valve cavity, and the center of the barrier chip is provided with a water shutting hole. An ejector rod which can move up and down in the through hole of the center of the gland is provided, and the upper end of the ejector rod is fixed with water shutting rubber which is positioned just below the water shutting hole. A floating body cavity communicated with the total water outlet pipe is arranged under the ejector rod, and a floating body is arranged in the floating body cavity. The utility model is small in volume and reliable in opening and closing.
Description
Technical field
The utility model relates to a kind of valve, specifically is a kind of automatic shutoff valve.
Background technique
In device such as the roof water tank of high residential building, the water storage box of solar water heater, the water storage box of flush toilet, all need a kind ofly can when fills with water, close the into automatic shutoff valve of water automatically.Generally be to adopt traditional float valve to realize this function in the existing said apparatus, but this structure needs a ball float that volume is bigger, and bigger distance is arranged again between ball float and the pipeline, this just makes that whole device volume is bigger, and use occasion is restricted.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of volume is little, the automatic shutoff valve of opening and closing reliable.
Automatic shutoff valve of the present utility model includes a valve body with water inlet manifold and water outlet, and the water outlet of valve body is communicated with total outlet pipe of below by the flow channel that is positioned at the valve body sidepiece; There is an involutory with it gland valve body below, constitutes valve pocket between gland inboard and the valve body; The elastic sheet rubber that the valve pocket middle part has an edge to be connected with the valve pocket inner wall sealing, elastic sheet rubber is divided into uuper valve chamber and lower valve chamber two-part with valve pocket; Uuper valve chamber is communicated with water inlet manifold, one section vertical water stopping tube is arranged in uuper valve chamber, the upper end of water stopping tube is connected with the water outlet of valve body by water channel, the lower end mouth of water stopping tube is smooth horizontal port, this port be positioned at above-mentioned elastic sheet rubber the upper surface inner ring directly over, (aperture is 0.2～1.2mm) then to have several apertures that are communicated with lower valve chamber on the outer ring of elastic sheet rubber; At the gland center through hole is arranged, a catch is arranged between this through hole and lower valve chamber, the edge of catch is connected with the lower valve chamber inner wall sealing, and there is water hole, a pass at the center of catch, and (aperture is 0.2～1.2mm); Be installed with a push rod that can move up and down in through hole in the through hole at gland center, gapped between push rod and the through hole, push rod upper end is fixed with one and closes water rubber, close water rubber be positioned at water hole, above-mentioned pass under; There is a buoyancy aid chamber that is communicated with total outlet pipe the below of push rod, is mounted with a buoyancy aid in the buoyancy aid chamber.
The utility model compact structure, volume are little, and can reliably realize closing water automatically behind the full water, can be applicable to various needs and close automatically in the water storing device of water function.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being numbered valve body 1, water inlet manifold 2, water outlet 3, flow channel 4, total outlet pipe 5, gland 6, elastic sheet rubber 7, uuper valve chamber 8, lower valve chamber 9, water stopping tube 10, water channel 11, aperture 12, through hole 13, catch 14, closing water hole 15, push rod 16, closing water rubber 17, buoyancy aid chamber 18, buoyancy aid 19, compressing tablet 20 among the figure.
Embodiment
As shown in the figure, in the automatic shutoff valve working procedure of the present utility model, when normal water inlet, current enter uuper valve chamber 8 by the water inlet manifold 2 of valve body 1, in uuper valve chamber, produce certain pressure, elastic sheet rubber 7 is out of shape downwards, the lower ending opening of water stopping tube is opened fully, current mainly arrive total outlet pipe 5 by water stopping tube 10 through water channel 11 and flow channel 4, and a spot of water flow to total outlet pipe 5 through small holes 12, lower valve chamber 9, water hole 15, pass, buoyancy aid chamber 18; When water tank is filled with in water inlet, water is overflow for 5 times by total outlet pipe, make water filling in the buoyancy aid chamber 18, and make buoyancy aid float 19 to float, buoyancy aid is with push rod 16 jack-up upwards, the pass water rubber 17 at push rod top can be pressed in 15 places, water hole, pass on the catch 14, because it is very little to close the aperture, water hole, therefore only need a very little pressure will close the water hole sealing, close sealing back, water hole and lower valve chamber can be filled with, and produce an outside hydraulic pressure, make upwards distortion and closely contact of elastic sheet rubber 7 with the lower end mouth of water stopping tube 10 by the current that aperture 12 enters lower valve chamber 9, with the water stopping tube sealing, thereby stop into water.In addition, also can be lined with the compressing tablet 20 of a slice rigidity, the sealing effect when contacting with water stopping tube 10 to strengthen elastic sheet rubber 7 at the lower surface of elastic sheet rubber 7.
