Description

Pressure-controlled automatic controller for water level

Technical field

The utility model relates to a kind of Water Level Control device, particularly a kind of pressure-controlled automatic controller for water level that utilizes the automatic control water level of water pressure.

Background technique

In the prior art, the container of water storage has water tower, pond, water tank etc., water tower and pond are the capital equipments of water storage and water supply, generally build in the high level of building materials thing, its water intake mode has that motor is pumped, tap water inserts, the controller that its automatic water supply system adopts is the buoyancy that produces by ball float, again by the transfer function of lever, promotes spool and makes valve closing.And the water level controller known except that float-ball type, that electric pole type and other are using, exist mostly that volume is big, heavy, complex structure and involve great expense, sensitivity and reliability be low, working life, problem such as weak point, maintenance difficult was unfavorable for applying.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved pressure-controlled automatic controller for water level is provided, and simplified structure reduces cost, and improves working sensitivity and reliability, increases the service life.

The purpose of this utility model can realize by following technical measures: this control valve has valve body, spool and core retainer plate, water intake and water outlet are arranged on the valve body, core retainer plate is fixed in the body cavity, core retainer plate offers the spool movable span, spool is installed in the spool movable span of core retainer plate, align water intake, can move up and down, the spool upper-end surface is provided with sealing gasket, and the lower end is connected and fixed at the barrier film medium position, the periphery of barrier film is fixed by following dividing plate and core retainer plate, and compressing sealing, barrier film is that soft sheet stock is made, and has spring to withstand between spool and the dividing plate, barrier film can be with the spool activity, spool, dividing plate is respectively equipped with the control through hole and runs through upper and lower end, and controlled water flow can be through control through hole circulation, is provided with flexible float-boarding below the dividing plate, flexible float-boarding is installed in the kickboard activity chamber of valve body, can move up and down, the control through hole corresponding position of flexible float-boarding and dividing plate is provided with sealing gasket, when flexible float-boarding moves up, but the control through hole of sealing gasket enclosed baffle, the kickboard activity chamber of valve body is provided with outside the discharge orifice connecting valve.Form an annular cavity between spool, core retainer plate and the valve body, water outlet is opened at intracavity sidewall, move the sealing water intake on the spool and close water, spool moves down connects water intake and water outlet boiling water, logical water intake on the control through hole of spool, under pass barrier film, the control through hole of dividing plate can be external through the discharge orifice connecting valve in kickboard activity chamber, forms a control room between barrier film and the dividing plate.

This control valve is placed suitable height place in water tower, the pond, and when water level hanged down, water was entered by water intake and promotes spool and barrier film moves down, and entery and delivery port is communicated with, and water flows into water tower through water outlet; Controlled water flow infilters through the control through hole of spool, and the control through hole of process dividing plate flows out from discharge orifice; When the water level of water tower rises to the flexible float-boarding height, be subjected to the water buoyancy function, flexible float-boarding moves up, the control through hole of the sealing gasket enclosed baffle on the flexible float-boarding, the water that flows into the control room produces upwards thrust to spool, spool moves up water intake, water outlet is separated, thereby stops into water; When the water level of water tower was lower than flexible float-boarding, flexible float-boarding moved down, and the control through hole of dividing plate is external through the discharge orifice connecting valve, and the control room does not have the hydraulic pressure effect, and spool, barrier film move down, and entery and delivery port is communicated with, and water flows into water tower through water outlet, so repeatedly.

The utility model reasonable in design, utilize buoyancy of water, pressure effect to realize control automatically, control is sensitive, reliable operation, stable performance, can be made by the first day of the lunar month material, it is simple in structure, long service life, installation and maintenance are convenient, with low cost, overcome many, the shortcoming such as leak of other water level controller fault, be widely used in the water level control of various water storage devices such as water tower, pond.
