Abstract
The utility model provides a water tower floating ball control valve, comprising a valve seat and a valve cover which are connected with each other. An entering water baffle plate, a valve plug, a sealing ring and a locating pull rod are arranged in an internal cavity of the water tower floating ball control valve. The entering water baffle plate is arranged on the bottom of the valve plug and embedded on the valve seat, the sealing ring is embedded in the groove of the internal cavity of the valve cover, and the valve plug is connected with the locating pull rod and extends through the valve cover; thus, a valve body switching mechanism of the control valve is formed. The locating pull rod is connected with a connecting pull rope and the floating ball to form a transmission mechanism to detect signals of water levels, and the locating pull rod forms a floating ball fixing mechanism over the floating ball with a hanging pole and a hanging plate which hang the float on the edge of the upper end of the water tower when used. The utility model has the advantages that along with the rise of the water level, the valve plug is pulled up for a certain distance by the floating ball and outlet water flow becomes small gradually, and when pushing force applied by the water on the valve plug reaches a certain value, the valve plug contacts the sealing ring to shut off the entering water. The utility model is characterized in that the valve plug is sealed by water pressure after being contacted with the sealing ring and turned off, thereby causing no leakage even under high water pressure.
Description
One, affiliated technical field:
The utility model relates to a kind of float valve that is used for the water tower automatic control of liquid.
Two, background technique:
Float valve is a kind of automatic control of liquid device commonly used in the various water tanks, and it is connected on the 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 adopt lever as driving mechanism, general valve plug moving direction is consistent with flow of fluid side, and when valve closing, valve plug moving direction antithesis, therefore the required power of closing of common valve is flow stream pressure and sealing force sum, ball float must provide enough buoyancy that valve cuts out, thereby common valve requires ball float that bigger volume is arranged, factory's very little with osculum design often, can increase sealing force like this, but pipe resistance increases, make water outlet slower, also can increase the 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, provide a kind of simple installation, simple in structure, flow is big and reliable another the 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, and it comprises valve seat, valve bonnet, valve plug, positioning tie bar, connection stay cord, ball float, peg, link plate.It is characterized in that the control valve body interior have one can only be up and down valve plug, positioning tie bar is equipped with at the valve plug center, positioning tie bar and top be connected connections such as stay cord, ball float.
As mentioned above, because the utility model has adopted new mentality of designing.Its advantage is that when closing, utilizing flow stream pressure to act directly on becomes the power of closing on the valve plug, so the flowing water bore is programmable bigger more than 1 times than common float valve, also water-tight in high hydraulic pressure situation.And under normal circumstances, this closes power always greater than sealing force, so no longer need to provide in addition the power of closing, the effect of ball float only limits to provide liquid level signal, thereby can significantly reduce the volume of ball float.
Four, description of drawings:
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the phase diagram of the utility model embodiment 1 when closing.
Fig. 3 is another form structure figure of embodiment.
Fig. 4 is inlet damper (2) structural drawing among the utility model embodiment.
Five, specific embodiments:
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing, other purpose of the present utility model and advantage will be described by this embodiment.
See also accompanying drawing, another water tower floater controlled valve of the present utility model is formed by connecting by valve seat (1) and valve bonnet (5), and inlet damper (2), valve plug (3) are housed in the chamber within it, seal ring (4) and positioning tie bar (6).Inlet damper (2) is in the bottom of valve plug (3), be to be embedded on the valve seat (1), seal ring (4) is inlayed on the inner chamber groove of valve bonnet (5), valve plug (3) and positioning tie bar (6) disjunctor, passing valve bonnet (5) center by positioning tie bar (6) has one to locate open-work accordingly with positioning tie bar (6), forms the main body switching mechanism of control valve.Positioning tie bar (6) be connected stay cord (7) and ball float (8) and be linked in sequence and form detect the driving mechanism of liquid level signal.The connection stay cord of being chatted (7) is used to regulate the height of water tower level, and ball float (8) is as the usefulness of level detection.Top and peg (9), link plate (10) at ball float (8) are formed the fixedly mechanism of ball float, by link plate (10) and peg (9) ball float are hung in the water tower upper end-face edge during use.
Know-why is: when anhydrous or water level was not enough to make ball float (8) to raise when water tower, valve plug (3) was resetted by the effect of its deadweight.When to water tower water-feeding, water flows into water tank along the valve body water outlet all around from valve body below through inlet damper (2) and valve plug (3), along with water level rise picking-up ball float (8) thus pull-up valve plug (3) is closed into water.
Its advantage is: ball float (8) rises along with water level and then pull-up valve plug (3) during to certain stroke, water outlet is pursued into and is diminished, and simultaneously the thrust of water is when the valve plug bottom affacts to a certain degree, and valve plug will fast rise, valve plug (3) contacts with seal ring (4), thereby closes into water.It is characterized in that it is pressure seal by water that valve plug (3) contacts with seal ring (4) after closing, therefore can be in high hydraulic pressure situation also antileaking.
