Abstract
Water tower floater controlled valve of the present utility model, be assembled by valve casing (4) and bonnet (1), sealing seat (5) is housed in valve shell cavity, sealing gasket (2) is embedded in be renovated on (3), will renovate with pin (10) the main body switching mechanism that (3) and torsion spring (9) are assemblied in the upper composition control valve of sealing seat (5).(3) center of renovating is equipped with bracing wire (7) and ball float (8) composition that is linked in sequence and is detected the driving mechanism of liquid level signal.Its advantage is: when ball float (8) rises along with water level and then pull-up renovates (3) to certain stroke, water outlet is by entering to diminish, simultaneously water thrust to renovate (3) bottom be applied to a certain degree time, renovate (3) will rise fast, renovate (3) to contact with sealing seat (5) with seal ring (2), thus close water inlet.It is characterized in that renovating (3) contacts closedown with sealing gasket (5) after it being the pressure seal by water, therefore can at high water pressures also antileaking.
Description
One, technical field:
The utility model relates to a kind of float valve for water tower automatic control of liquid.
two, background technique:
Float valve is a kind of liquid-level auto-control device conventional in various water tank, and it is connected on water supply pipeline, controls its action by ball float, when liquid level reach a certain height, makes float valve close water outlet by ball float.The float valve that tradition is common, owing to adopting lever as driving mechanism, general plug movement direction is consistent with flow of fluid side, and when valve closing, plug movement direction antithesis, therefore the closing forces needed for common valve is flow stream pressure and sealing force sum, ball float must provide enough buoyancy that valve just can be made to close, thus common valve requires that ball float has larger volume, what often osculum designed by factory is very little, sealing force can be increased like this, but pipe resistance increases, make water outlet comparatively slow, also can increase water pump load.
three, summary of the invention:
The purpose of this utility model is to overcome the many deficiencys of traditional common float valve, provides that a kind of simple installation, structure are simple, flow is large and the reliable water tower floater controlled valve of seal force.
The design concept of water tower floater controlled valve of the present utility model is as follows, it comprises valve casing, bonnet, sealing seat, renovates, anti-polluting tube, bracing wire, ball float.It is characterized in that control valve body interior has one to renovate, bracing wire is equipped with at the center of renovating, and line is connected with ball float.
As mentioned above, because the utility model have employed new mentality of designing.Its advantage is, when closing, utilizing flow stream pressure to act directly on valve gap becomes closing forces, and therefore programmable larger than common float valve more than 1 times of flowing water bore, also water-tight at high water pressures.And under normal circumstances, this closing forces is always greater than sealing force, so no longer need to provide closing forces in addition, the effect of ball float is only limitted to provide liquid level signal, thus can greatly reduce the volume of ball float.
four, accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the phase diagram of the utility model embodiment when closing.
five, specific embodiments:
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing, other object of the present utility model and advantage will be described by this embodiment.
Refer to accompanying drawing, water tower floater controlled valve of the present utility model is assembled by valve casing (4) and bonnet (1), sealing seat (5) is housed in valve shell cavity, sealing gasket (2) is embedded in be renovated on (3), will renovate with pin (10) the main body switching mechanism that (3) and torsion spring (9) are assemblied in the upper composition control valve of sealing seat (5).(3) center of renovating is equipped with bracing wire (7) and ball float (8) composition that is linked in sequence and is detected the driving mechanism of liquid level signal.
Know-why is: when water tower is anhydrous or water level is not enough to make ball float (8) raise, turnover panel (3) is resetted by the effect of torsion spring (9).When to water tower water-feeding, water below valve body through upper seal seat (5), anti-polluting tube (6) water outlet flow into water tank, along with water level rise hold up ball float (8) thus pull-up renovate (3) close water inlet.
Its advantage is: when ball float (8) rises along with water level and then pull-up renovates (3) to certain stroke, water outlet is by entering to diminish, simultaneously water thrust to renovate (3) bottom be applied to a certain degree time, renovate (3) will rise fast, renovate (3) to contact with sealing seat (5) with seal ring (2), thus close water inlet.It is characterized in that renovating (3) contacts closedown with sealing gasket (5) after it being the pressure seal by water, therefore can at high water pressures also antileaking.
