Abstract
The utility model relates to the hardware industry and is especially the valve type used for the automatic controlling of the water level. The utility model is mainly composed of a valve body, a valve cover, a seal membrane, a controlling core, a small seal ring, a float ball, a float ball lever etc. Two empty chambers are arranged in the valve. The float ball goes up and down following with the water level to drive the controlling core to move. The controlling core controls the connecting and the blocking between the two empty chambers and the outside world. The controlling of the pressure difference change between the empty chambers is achieved and the seal membrane moving up and down following with the pressure difference can achieve the opening and closing of the valve. The utility model is self-locked and sealed by the water pressure and the utility model has the advantages of the reliable seal, the sensitive opening and closing, the not existing of abrasion of the seal element, the long service life etc. The utility model can be injection-molded by the engineering plastic and has the very low cost and the simple production process.
Description
Affiliated technical field
The utility model relates to hardware industry, especially for the valve class that water level is controlled.
Background technique
The old-fashioned copper float valve of always continuing to use all the year round, lever augmented by the buoyancy of ball float by ball lever, make seal rubber pad force to block the drain opening sealing, carry out closing of valve.Exist sealing reliability low, the shortcoming that working life is short.The new-type copper float valve of extensively promoting the use of in recent years is to have increased by one to apply mechanically hydraulic pressure pressure reduction control keying on old-fashioned valve, by the parts that spring force seals, sealing reliability is increased.But still deposit the spring fatiguability, Sealing moves in seal process and is subjected to fretting wear, influences the high deficiency of Acceptable life cost.
Summary of the invention
Have new-type copper float valve cost height now in order to overcome, the deficiency that Acceptable life is short, it is a kind of by the hydraulic self-locking sealing that the utility model provides, and simple in structure, Sealing does not have the float valve of wearing and tearing.
Be provided with sealing film and bearing plate between the valve body of band waste pipe and connected pore channel and the valve gap of convex shelly, they and valve cover chamber form the transformation chamber, and rising portion forms hydraulic chamber especially in valve interior wall and the draining pipe valve between wall, and sealing film and bearing plate can move up and down opens or seal the waste pipe top port.Hydraulic chamber communicates with supply channel, and the connected pore channel on the valve body is communicated with transformation chamber, the hydraulic chamber and the external world.Move forward and backward by the control core that ball lever can drive in the connected pore channel by ball float, with the break-make between control transformation chamber and the hydraulic chamber, the little seal ring control connected pore channel and the extraneous break-make of control core rear end.When valve cut out: ball float rose with water level and promotes the reach of control core by ball lever, links up transformation chamber and hydraulic chamber and constantly enlarges overflow section; Connected pore channel and constantly reduce until being closed simultaneously with the overflow section in the external world.Supplying water therebetween constantly to inject also when waste pipe constantly discharges is full of the transformation chamber rapidly, and bearing plate and sealing film are moved down until sealing the waste pipe top port.At this moment, transformation chamber and hydraulic chamber are because of being communicated with, and hydraulic pressure is in state of equilibrium.Because of waste pipe communicates with the external world, the pressure difference that the corresponding waste pipe area of contour in transformation chamber partly forms promptly is a sealing load, makes sealing film seal up the waste pipe upper end-hole by bearing plate, realizes the hydraulic self-locking sealing.During opening of valves: ball float drives the control core with drawdown by ball lever and moves outward, opens the connected pore channel with extraneous outlet and constantly enlarge overflow section, constantly reduces overflow section between transformation chamber and the hydraulic chamber simultaneously until being blocked.Therebetween, the indoor water of transformation is constantly discharged from the outlet of connected pore channel, the indoor hydraulic pressure of transformation reduces rapidly, backpressure difference between hydraulic chamber and transformation chamber increases rapidly and promotes moves on sealing film and the bearing plate, open the waste pipe top ports, supply water and just directly discharge, finish the unlatching of valve from waste pipe.
The beneficial effects of the utility model are: realize the hydraulic self-locking sealing, the sealing reliability height, the keying control force is little, drain discharge is big, and Sealing does not have fretting wear, and the product Acceptable life is long, simple in structure, suit to make, can significantly reduce cost, save non-ferrous metal and consume with the engineering plastics molding and forming.
