Abstract
The utility model relates to a float valve for a normal closed water tank. The utility model is characterized in that a valve core propped and pressed by a spring is arranged in a valve cavity of a valve body, and a valve core sleeve is arranged in a nut of the hollow valve cavity; a sealing ring on a flange of the valve core is sealed and pasted on the lower edge of the nut of the hollow valve cavity under the propping and pressing operation of the spring to block water, so that the utility model is in a normal closed state. A water service hole is arranged above the sealing ring of the valve core, and the upper end of a valve rod which is provided with a water level adjusting rod and is arranged in an inner cavity of the valve core is connected with a float lever. When the water level in the water tank is descend, the lever can downwards press the push rod and the valve core, so that a float can make water in the water service pipe injected in the water tank by the water service hole on the valve core. The float valve of the normal closed water tank has the advantages of simple structure, reliable use and long service life. Moreover, the utility model can stop the overflow phenomenon of the water tank, and the utility model is the new product replacing the float valve of the existing normal open water tank.
Description
Technical field
The utility model relates to the water tank valve member, promptly a kind of float for water tank valve.
Background technology
The float for water tank valve that water storage containers such as existing high level cistern and toilet seat water tank use is float-controlled valve open in usual, and spool does not have external force and is opening as the time spent, closes through lever by buoyancy.This float-controlled valve open in usual is tight-closed, just need bigger buoyancy, so stressed member is fragile, and to making the water tank spilling water, waste is serious, even cisco unity malfunction.Therefore, the improvement of float for water tank valve just becomes an important topic.
Summary of the invention
The utility model is exactly a kind of normally closed type float for water tank valve that designs at the defective of existing float for water tank valve.This float for water tank valve is by the water tank seat pipe that is fixed on water tank bottom and place valve body, spool in the water tank, and lever and float are formed.The spool that the spring roof pressure is arranged in the valve pocket of valve body, valve core housing places in the hollow valve pocket nut, there is sealing ring to contact on the flange of spool with hollow valve pocket nut lower edge, there is the limbers sealing ring top of spool, place the valve rod upper end of valve core cavity to link to each other with lever, the fulcrum of lever links to each other with support arm on the valve body, and the lever other end has float, and valve pocket is connected with feed pipe through the bottom water block.
As another embodiment of the present utility model, water tank seat pipe is horizontally placed on water tank wall, and valve body is whole to be inverted, and the inner chamber of valve body communicates with water tank seat tube cavity and feed pipe through the sidewall through hole.In addition, the regulating water level part can be arranged with the regulation and control cistern water level on the valve rod in the spool.Mass is arranged to regulate buoyancy in the cavity of float.Sealing ring is an O-ring seals.
The spool of the utility model normally closed type float for water tank valve is pushed by spring, and sealing ring on the spool flange and hollow valve pocket nut lower edge press sealing, make float-controlled valve become normally off, difficultly leaks, the spilling water phenomenon.Have only when valve rod float with water tank in drawdown, just can open spool when pushing away spool down, make the limbers of water on spool in the valve body valve pocket enter valve core cavity, inject water tank.By the regulating water level part regulating valve stem length on the valve rod, adjustable cistern water level.By the mass in the increase and decrease float cavity, can regulate float buoyancy.This normally closed type float for water tank valve arrangement is simple, is easy to install, regulate, and uses reliably, can stop radiator leak, spilling water phenomenon, is the renewal product of existing float for water tank valve open in usual.
