Abstract
The utility model relates to a float valve comprising a connecting bar, wherein one end of the connecting bar is provided with a float ball, and the other side thereof is provided with a rubber plug. The float valve is further provided with a pressure accumulation chamber which is provided with a water outlet and a water inlet, and the rubber plug is connected with the water outlet in the pressure accumulation chamber, the bottom of the pressure accumulation chamber is provided with a rubber sheet whose lower portion is connected with a mouth of an inlet pipe. The utility model provided with the pressure accumulation chamber makes use of the increasing and reducing of the pressure in the pressure accumulation chamber to control the up or down movements of the rubber sheet, thereby controlling the watering to the case body of the inlet pipe or stopping the watering. The size of the float ball has nothing to do with the diameter of the inlet pipe, and the float ball can be made with a comparatively small volume, thereby saving the manufacture materials of the float ball, and the float ball can be made from plastic rubber, which can further reduce the cost.
Description
Technical field
The utility model belongs to the water-level control apparatus technical field, the float valve that relate in particular to a kind of not cracky, energy saving, reduces cost.
Background technique
At present the float valve that generally uses on the market is made up of ball float 2, connecting rod 1, rubber stopper 3, and as shown in Figure 1, one of ball float 2 and connecting rod 1 links to each other, and the other end of connecting rod 1 is connected with rubber stopper 3 in the horizontal direction, the mouth of pipe flexible connection of rubber stopper 3 and intake pipe 8.The float valve of this structure when the thrust of connecting rod during greater than the pressure of intake pipe, just can make rubber stopper seal intake pipe.The area of the intake pipe mouth of pipe is big more, and pressure is big more; And the buoyancy of ball float is big more, and then thrust is big more.So the intake pipe mouth of pipe is big more, require the volume of ball float also big more.And general ball float all is to make with valuable copper or stainless steel, thereby the big more cost of volume is just high more, and damages easily.
Summary of the invention
The utility model mainly is to solve original float valve cost height, raw material expense, the easy technical problem of damaging; Provide a kind of saving raw material, cost low, and non-damageable float valve.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises connecting rod, one of connecting rod is provided with ball float, the other end of connecting rod is provided with rubber stopper, described float valve also is provided with a poly-chamber of pressing, the poly-chamber of pressing is provided with poly-chamber osculum, the poly-water inlet, chamber of pressing of pressing, described rubber stopper links to each other with the poly-chamber osculum of pressing, water inlet, described poly-pressure chamber communicates with intake pipe, the bottom surface of described poly-pressure chamber is provided with sheet rubber, and the sheet rubber below links to each other with the intake pipe mouth of pipe.When the water surface descended, ball float descended, and draws back rubber stopper, the poly-chamber osculum of pressing is opened, and pressure reduces, and pushes away sheet rubber on the current in the intake pipe, water inlet pipe mouth is separated with sheet rubber, and current pour in the casing, and it is indoor that some current passes through the poly-poly-pressure of water inlet, chamber inflow of pressing simultaneously.Along with the rising of water level in the casing, ball float rises, and when rising to certain position, rubber stopper is sealed the poly-chamber osculum of pressing, and presses the indoor water yield to increase along with poly-, and inner air is compressed, and pressure increases, and presses down sheet rubber, makes it to seal the intake pipe mouth of pipe, stops priming petock.Therefore water inlet pipe mouth open or close relevant with the poly-chamber of pressing, irrelevant with the size of ball float, ball float can be done lessly, the saving cost.
As preferably, the aperture, water inlet of described poly-pressure chamber is less than poly-osculum aperture of pressing the chamber.When making rubber stopper not seal poly-pressure chamber osculum, gather and press the indoor pressure that almost do not have, the water in the intake pipe can unimpededly pour in the casing.
As preferably, top, described poly-pressure chamber is provided with boss, and described poly-pressure chamber osculum is located in the described boss.When the indoor water level of poly-pressure rises to ostium excurrens, the indoor air of poly-pressure just can not discharge, guarantee the poly-indoor certain air that leaves of pressing, along with being pushed by water, assemble certain potential energy, guarantee that poly-the pressure indoorly has enough moving sheet rubbers of trying hard to recommend to move downward, seal the water pipe link as required securely, continue to pour water thereby stop.
As preferably, water inlet, described poly-pressure chamber is located on the described sheet rubber and is corresponding with the intake pipe nozzle position.Conserve space, easily manufactured.
As preferably, the indoor deadweight water shutoff bar that also is provided with of described poly-pressure, described deadweight water shutoff bar is positioned at the top of water inlet, described poly-pressure chamber.When poly-pressure of pressing chamber and intake pipe when equating, deadweight water shutoff bar falls to sealing the poly-water inlet, chamber of pressing, and prevents from poly-ly to press indoor water to pass back into intake pipe, the poly-chamber of pressing keeps the highest pressure, guarantees that further sheet rubber blocks intake pipe securely.
As preferably, top, described poly-pressure chamber is provided with slide rail, and described deadweight water shutoff bar is located in the described slide rail.
As preferably, the top of described poly-pressure chamber is located in water inlet, described poly-pressure chamber, and the poly-lower end mouth of water inlet, chamber of pressing is provided with safety check, and described safety check is provided with foam; Described intake pipe also is provided with mouth of pipe B, and mouth of pipe B links to each other with water inlet, described poly-pressure chamber.After poly-pressure chamber osculum is plugged, the indoor water level of poly-pressure rises, when poly-pressure of pressing chamber and intake pipe when equating, under buoyancy function, the safety check come-up is blocked the poly-water inlet, chamber of pressing, prevent from poly-to press indoor water to pass back into intake pipe, make the poly-chamber of pressing keep the highest pressure, guarantee that further sheet rubber blocks intake pipe securely.
As preferably, described intake pipe is provided with the water pipe link near the termination of sheet rubber, described water pipe link near the caliber at sheet rubber place less than with the caliber of intake pipe connecting place, and the water pipe link is near the orifice area at the sheet rubber place area less than described sheet rubber.The lifting surface area on plane stressed and long-pending greater than lower plane on the sheet rubber, after ball float rises to certain position, guarantee that further poly-the pressure indoorly has enough moving sheet rubbers of trying hard to recommend to move downward, seal the water pipe link as required securely, continue to pour water thereby stop.
The beneficial effects of the utility model are: by the poly-chamber of pressing is set, utilize poly-press the increase of indoor pressure or reduce control sheet rubber on move or fall, thereby the control intake pipe is poured water in casing or is stopped to pour water, therefore the size of the size of ball float and intake pipe caliber is irrelevant, and ball float can be made smaller volume, saves the use amount of the material of making ball float, buoyancy is little, requirement of mechanical strength is low, can make of plastic material, further reduces cost.
