Abstract
The utility model discloses a switching valve for a water storage tank, which comprises a sleeve barrel provided with an upper end cover and a lower end cover, wherein the lower end cover and the upper end cover are respectively provided with a water inlet hole and an air inlet, a float is arranged in the sleeve barrel, the periphery of the air inlet of the upper end cover is provided with an elastic sealing ring and the upper end of the float which corresponds to the air inlet is provided with an elastic sealed cap which can open or close the air inlet. Since each air inlet of the utility model is elastically sealed, the sealing effect of the utility model is better.
Description
Technical field
The utility model belongs to the device that tap water catchments and fetches water, and relates in particular to a kind of water tank switch valve.
Background technique
In water system, for guaranteeing constant pressure water supply, often adopt the secondary pressurization, second pressure water supply must be provided with water storage box, and for anti-sealing is polluted, water storage box generally seals.But at water use peak, the pressure in the water storage box can be lower than the pressure of tap water pipe network, at this moment, negative pressure can occur in the case, violates the provisions of the relevant regulations issued by the State.Therefore water storage box need use the water tank switch valve, and the air that promptly can suck and breathe out prevents to produce in the water storage box negative pressure.The patent No. is that 00122854.4 patent of invention discloses a kind of water tank switch valve, and this water tank switch valve has telescopic shell, and float is set in the sleeve, and float connects centering magnet; The sleeve lower end is connected with water storage box, and upper end cap has suction tude.When in the water storage box during drawdown, float and centering magnet fall under action of gravity, and air enters water storage box through the water tank switch valve, make can not produce negative pressure in the water storage box; When water level in the water storage box rose, the air in the water storage box was breathed out through the water tank switch valve, and when water level arrived the height that is provided with, float rose with water level, promotes centering magnet the suction tude mouth of pipe is closed.The conduit of water tank switch valve is communicated with air-strainer and enters water storage box to avoid dust in air, impurity.
When reality is used, there is following deficiency in this water tank switch valve: a) centering magnet and air inlet mouth of pipe sealing effect are bad, the phenomenon that water in the water storage box flows out from the water tank switch valve often appears, and use after a period of time and cause two part cooperation places all to produce wearing and tearing, reduced sealability more because frequent switching is impacted; B) fast rise of water level is too big to float, centering magnet impact, causes the damage of part easily.C) the external air-strainer of switch valve conduit, it is bigger to take up room.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of and is not easy to seep water, the water tank switch valve of durable, simple in structure, opening and closing reliable.
The utility model provides a kind of water tank switch valve, comprise sleeve, sleeve has upper end cap and lower end cap, water inlet and inlet hole are set respectively on lower end cap and the upper end cap, float is set in the sleeve, the inlet hole periphery of upper end cap is provided with elastic seal ring, and the float upper end of corresponding inlet hole is provided with the elastic seal cap of closure or openness inlet hole.
Above the lower end cap water inlet, cushioning fender is set; The housing of dress air filter in the upper end cap top is provided with, itself and upper end cap are to removably connect; Float is connected by guide rod with sealed cap, and this guide rod passes sealed cap and extends upwardly in the air filter housing, is slidingly matched with the conduit formation that is arranged in the housing; Be spherical in described cushioning fender; The fixedly connected pillar in described cushioning fender bottom, the column of itself and lower end cap upper surface forms clamping.
The utility model makes sealing effect better because the sealing of inlet hole is an elastic packing; Because water intake is provided with cushioning fender, avoided the impact of water simultaneously, prolonged working life parts such as floats; Because air-strainer and switch valve fuse, and have reduced taking up room of component, it is simple and convenient to change air-strainer; Because the setting of guide rod and conduit, make float and connected strictly move vertically, realize the switching of suction port exactly, improved the reliability of action.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
The utility model embodiment as shown in Figure 1, it comprises the sleeve 1 that has upper end cap 6 and lower end cap 14, upper end cap 6 centers have inlet hole 4, the center of lower end cap 14 has water inlet 12; There is housing 2 top of sleeve 1, and housing 2 is clamping with sleeve 1, and the sidewall of housing 2 has a plurality of apertures 3, and air-strainer 15 is housed in the cavity of housing 2; Float 13 is arranged in the sleeve 1; Float 13 is connected by the elastic seal cap 9 of guide rod 8 with its top; The lower end mouth of inlet hole 4 is bonded with elastic seal ring 7, and its internal diameter and inlet hole 4 are basic identical; Guide rod 8 passes elastic seal cap 9 and extends up through inlet hole 9, and the conduit 5 on its upper end and the housing 2 forms and is slidingly matched; The top of sleeve 1 inherent water inlet 12 is provided with domed cushioning fender 10, and the double-screw bolt 11 of it and lower end cap 14 upper surfaces forms clampings.
During actual the use, when water level was lower than switch valve, float 13, guide rod 8 and sealed cap 9 were in extreme lower position, and inlet hole 4 is opened; During water filling, the air in the pond is discharged to ambient atmosphere by the cavity in water inlet 12, the sleeve 1, inlet hole 4, housing 2 and wherein air-strainer, aperture 3 in the pond; When the pool inner water position constantly raises, water will be from the water inlet 12 enters in the sleeve 1 and promotes float 13, guide rod 8, elastic seal cap 9 and move upward, and is pressed on the elastic seal ring 7 until elastic seal cap 9 inlet hole 4 is blocked fully; During drawdown, float 13, guide rod 8, elastic seal cap 9 move down until extreme lower position thereupon in the water tank, and air enters in the water tank by air-strainer, inlet hole 4, the cavity of sleeve 1, water inlet 12 in aperture 3, the housing 2.
The effect of conduit 5 is to guarantee that float 13, guide rod 8 and elastic seal cap 9 strictnesses are mobile vertically, avoids deflection to cause the bad or other problem of sealing; The effect of cushioning fender 10 is that water plays buffer function to current when entering in the sleeve 1, reduces the impact of current to parts such as floats, prolongs its working life; Because sealed cap 9 and seal ring 7 all are elastic components, make both be combined with better sealing effect, avoid water to flow out or ooze out from inlet hole 4.
