Abstract
The utility model relates to a float valve core, belonging to technical field of pipeline valves. The float valve core is composed of a fixing valve core (2) with an empty cavity, a movable valve core (1) which is provided with an empty cavity (3) and matched with a rotation shaft (4), a rotation shaft (4) on which a nut (5), a connection rod (6) and a float ball (7) are arranged. The utility model has the advantages of simple structure, low cost, long life span, high reliability and good sealing.
Description
Technical field:
The utility model relates to a kind of Flat valve core, metal conduit valve technology field.
Background technique:
Used float valve adopts floating ball rod to promote spool to-and-fro motion switch fluid.Have weak point in working life, poor reliability, fit badly when hydraulic pressure is high, shortcomings such as linkage mechanism is stuck easily, easy leakage.
Summary of the invention:
In order to overcome the deficiency of prior art, and provide a kind of Flat valve core.
The technical solution adopted in the utility model is: this Flat valve core is by the fixed valve plug that has cavity on it (2), have the movable valve plug (1) of cavity (3) on its that cooperates with rotating shaft (4), the rotating shaft (4) that is fixed with nut (5), connecting rod (6) and ball float (7) on it is formed.
The utlity model has advantages such as mechanism is simple, cost is low, the life-span is long, reliability is high, good airproof performance.
Description of drawings:
Accompanying drawing is the utility model structure scheme of installation.
The utility model structure is not only limited to shown in the accompanying drawing.
Embodiment:
The spool of the utility model structure is packed in the valve seat that matches, in the occasion that float valve is placed in required control.When liquid position did not reach design load, ball float (7) let droop by deadweight, drive rotating shaft (4) and movable valve plug (1) simultaneously and rotate, when the cavity (3) on the movable valve plug (1) when cavity on the fixed valve plug (2) communicates, liquid enters.Along with entering of liquid, ball float (7) upwards floats gradually by buoyancy, drives rotating shaft (4) and movable valve plug (1) simultaneously and rotates, and when the dislocation of the cavity on cavity (3) on the movable valve plug (1) and the fixed valve plug (2), liquid stops to enter.
Claims (1)
- A kind of Flat valve core is characterized in that this Flat valve core by the spool that has cavity on it (2), has the spool (1) of cavity (3) on its that cooperates with rotating shaft (4), and the rotating shaft (4) that is fixed with nut (5), connecting rod (6) and ball float (7) on it is formed.
