Abstract
The utility model discloses an automatic liquid level control valve used for various water tanks, cisterns and sinks in civil constructions and industrial and mining enterprises, which is composed of a valve seat, a valve body arrangd on the valve seat, a float bowl with a lever and a small valve core arranged on the lower part of the valve seat and a protection cylinder. The utility model is characterized in that a flow-limited hole is arranged on the valve seat corresponding to the small valve core, the joint of the valve seat and the valve body is provided with septum, and the upper cavity of the septum is communicated with the lower cavity via the flow-limited hole; the valve of a water outlet pipe is arranged on the center of the valve body, the valve is arranged at the backward direction with the water inlet of the valve body, and the water outlet of the water outlet pipe is extended from the valve body and towards bottom; a valve pressure cover is arranged on the septum, and a spring is arranged between the lower side of the septum and the valve seat.
Description
The utility model relates to a kind of valve mechanism, particularly a kind of liquid level automatic control valve of using among various water tanks, water tower, the pond in covil construction, the industrial and mining enterprises that is installed on.
Used operation valve among present various water tank, water tower, the pond is generally all used lever ball-cock assembly and all kinds of piston hydraulic altitude valve.Piston hydraulic altitude valve weak point is that piston and O-ring seal are easily stuck and make valve invalidation by impurity, and functional reliability is poor.
The purpose of this utility model is to provide a kind of liquid level automatic control valve, and the prior art structure is improved, and directly relies on pipeline internal medium pressure-driven valve, improves functional reliability.
To achieve these goals, the utility model adopts following technical scheme: a kind of liquid level automatic control valve, comprise a protection cylinder, one is located at the floating drum that fluctuates in the protection cylinder, a lever that is connected with floating drum and a small valve core that links with lever, it is characterized in that valve seat of protection cylinder connection suitable for reading, be provided with a vertical metering hole on the valve seat over against the small valve core place, the top of valve seat connects valve body, valve seat and valve body joint portion laterally are provided with a barrier film, the valve body bottom margin is provided with the metering hole that is communicated with body cavity, equally respectively be provided with the metering hole that is communicated with the barrier film cavity of resorption on diaphragm edge corresponding and the valve cup rim with this metering hole, the valve of rising pipe is located at valve body central authorities, this valve and valve inleting water mouth oppositely are provided with, the water delivering orifice of rising pipe stretches out valve body and down, diaphragms is provided with a valve gland over against rising pipe valve place, be provided with a spring between barrier film and the valve cup bottom, spring places in the spring base, upper spring seat is fixed on below the barrier film, and lower spring cup is located on the valve cup bottom.
Compared with the prior art the utility model has apparent face and easily see advantage: directly rely on pipeline internal medium pressure-driven valve, the seal degree height has improved functional reliability, and compact conformation is reasonable; Valve closing is steady, nothing is gone out, shaken; Adopt rush-resisting material manufacturings, corrosion-resistant, pollution-free such as brass; Barrier film adopts high-quality folder fabric rubber to make long service life.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is the utility model structural representation.
As shown in the figure, the utility model is made up of valve body 1, valve seat 4, floating drum 7 and protection cylinder 8.Floating drum is located in the protection cylinder, and can fluctuate, and connects a lever 6 on the floating drum, this lever and small valve core 5 interlocks that are located on the valve seat.It is suitable for reading that valve seat is installed in protection cylinder, is provided with a vertical metering hole 41 over against the small valve core place on the valve seat, and valve body is installed on the top of valve seat, and valve seat and valve body joint portion laterally are provided with a barrier film 2, and this barrier film adopts the high-quality folder to knit the rubber manufacturing.Establish a metering hole 11 that is communicated with body cavity on the valve body bottom margin, equally respectively be provided with the metering hole 21,42 that is communicated with the barrier film cavity of resorption on diaphragm edge corresponding and the valve cup rim with this metering hole.The valve 121 of rising pipe 12 is located at valve body central authorities, and this valve and valve inleting water mouth 13 oppositely are provided with, and the water delivering orifice 122 of valve body rising pipe stretches out valve body and down.Diaphragms is provided with a valve gland 22 over against rising pipe valve place, and this gland is fixed on the barrier film by screw rod.Establish a spring 3 between barrier film and the valve cup bottom 43, spring places in the spring base 31,32, and upper spring seat 31 is fixed on by screw rod below the barrier film, and lower spring cup 32 is located on the valve cup bottom.The metering hole that the utility model is communicated with the barrier film upper and lower cavity equally also can be located on the barrier film.During use the utility model water inlet joint is screwed on water inlet pipe, when liquid level in the water tank descended, the valve lower buoy steadily descended thereupon, and small valve core is opened, draining, and the release of barrier film cavity of resorption, pressure water promotion barrier film descends the valve water supply start in the pipeline; Floating drum floated thereupon when liquid level rose in the water tank, and small valve core is closed the barrier film cavity of resorption becomes annular seal space, and the pressure water that is entered the barrier film cavity of resorption by water inlet pipe through metering hole promotes to move on the barrier film, valve closing, and water supply stops.
