Abstract

The utility model relates to a water inlet control valve for various liquid containers such as a water tank and the like, in particular to a water level control valve for a floating plate water tank. The water level control valve comprises a valve body, a valve core and a connecting rod, wherein a valve assembly consisting of the valve body and the valve core is arranged on a water inlet pipe of the water tank; one end of the connecting rod is connected with the valve core, and the other end of the connecting rod is hinged with a floating body; and the floating body is a floating plate formed by combining an upper layer hard plastic plate with a lower layer foam plate. The water level control valve has the advantages that the upward and downward floatation of the floating body, caused by water surface fluctuation can be eliminated, the water hammering can be prevented, the pipeline noise is lowered, the service lives of a pipeline and a floating plate valve are prolonged, the manufacturing cost is low, and the water supply is stable.

Description

Kickboard formula cistern water level control valve

Technical field

The utility model relates to the water inlet control valve of various liquid-containers such as water tank, specifically is a kind of kickboard formula cistern water level control valve.

Background technique

Various liquid-containers such as water tank are the indispensable parts of present productive life, for reaching the requirement of automatic control liquid level, often adopt spherical float valve control water level at water tank inlet.Because the fluctuation ball float of the water surface fluctuates in water easily, when causing the float valve water outlet and when unlatching and closing produces water hammer in pipeline, make pipeline produce noise, for a long time may bad pipeline of an ancient egg-shaped, holed wind instrument and float valve.Economical and practical, simple structure, easy to operate.

Summary of the invention

The utility model is intended to solve the problems referred to above that existing float valve exists, and a kind of floating body that adopts floating plate as valve is provided, and can prevent that water hammer from producing, and reduces the pipeline noise, protection pipeline and pipe fitting, kickboard formula cistern water level control valve with low cost.

The technological scheme that the described problem that solves the utility model adopts is: a kind of kickboard formula cistern water level control valve, comprise valve body, spool, connecting rod, the valve assembly of being made up of described valve body, spool is installed on the intake pipe of water tank, described connecting rod one end is connected with spool, the other end and a floating body are hinged, and this floating body is the floating plate that the foam plate by the hard plastic board on upper strata and lower floor is combined into.

Compare with existing float valve, the beneficial effects of the utility model are: eliminated because the floating body that water level fluctuation causes fluctuates, prevented the generation of water hammer, reduced the pipeline noise, prolonged working life of pipeline and kickboard valve, and cheap, it is stable to supply water.

Description of drawings

Fig. 1 is the structural representation when installing and using state of the present utility model.

Fig. 2 is a plan structure schematic representation of the present utility model.

Among the figure: water tank 1, intake pipe 2, valve body 3, spool 4, connecting rod 5, hard plastic board 6, foam plate 7.

Embodiment

Referring to Fig. 1, Fig. 2, the valve assembly of being made up of valve body 3, spool 4 in this kickboard formula cistern water level control valve is installed on the intake pipe 2 of water tank 1, end by the connecting rod 5 that stainless steel is made is connected with the spool 4 that control valve is opened, these connecting rod 5 the other ends and a floating body are hinged, and this floating body is the floating plate that the foam plate 7 by the hard plastic board 6 on upper strata and lower floor is combined into.

Working principle of the present utility model: floating plate floats on the surface, when reducing, water level drives spools 4 rotations with valve open because the deadweight of floating plate can be passed through connecting rod 5, water flows out by valve. along with the continuous rising of liquid level, floating plate also floats thereupon gradually, and hold up its upper links 5 simultaneously, turn valve valve closing the most at last gradually down, thereby reach the water level in the control water tank 1.In this course, because the area of floating plate is bigger, floating plate can occupy the one or more crests and the trough of ripples simultaneously when the water surface rocks in the water tank 1, thereby avoided fluctuating of floating plate, regulating valve switch that can be stable, the accurate control water level of final realization is eliminated the effect of water hammer.

Claims

1. kickboard formula cistern water level control valve, comprise valve body, spool, connecting rod, it is characterized in that, the valve assembly of being made up of described valve body, spool is installed on the intake pipe of water tank, described connecting rod one end is connected with spool, the other end and a floating body are hinged, and this floating body is the floating plate that the foam plate by the hard plastic board on upper strata and lower floor is combined into.
