Abstract
The invention belongs to the manufacturing field of valves, in particular to a two-stage feedback type automatic valve for the intercepting control of various liquid containers, comprising a valve body, a valve seat, a valve core and a floater, wherein the joint of the valve body and the valve seat is installed with the valve core; a water inlet and a water outlet are arranged on the valve body; a water bag chamber is formed between the upper part of the valve seat and the valve core, and the lower part of the valve seat is provided with a floater chamber in which the floater is arranged; and a limber communicated with the water bag chamber and the floater chamber is arranged on the valve seat, the bottom of the valve seat is provided with an opening, and a water discharging port on the side surface of the valve seat is positioned at the upper part of the floater chamber. The two-stage feedback type automatic valve is installed above a container with safety and reliability, and can greatly reduce the water overflowing failure rate without a large maintenance hole. When the two-stage feedback type automatic valve is maintained, as long as a pipeline is upwards pulled out, the automatic valve can be taken out for replacement with convenience, thereby solving the problem of difficult maintenance, and liquid in the container does not need to be discharged so that the unnecessary waste is reduced. The two-stage feedback type automatic valve is suitable for more fields of water containers, thin oil containers, low-viscosity organic containers and the like and is suitable for wide generalization.
Description
One, technical field
The invention belongs to valve and manufacture field, be specifically related to a kind of secondary feedback type automatic valve that dams and control for various liquid-containers.
Two, background technique
At present, the automatic water feeding valve of most liquid container is all to adopt cursory drive lever transmission moment, compresses water outlet and realizes automatic-diversion closure control.This self-acting valve need to be arranged on side or the below of container, will above container, leave very large service hatch when mounted, and when maintenance, the liquid medium in container need to be bled off, and brings inconvenience and wastes.Adopt the water supply system of such self-acting valve, because water overflow faults rate is high, often need to send special messenger to manage, cause the waste of manpower.And adopt advanced electronic signal feedback control, and though can realize stable self water feeding, reducing water overflow faults rate, its cost is high, and expense is large and cannot solve the difficult problem of maintenance.
Three, summary of the invention
The object of this invention is to provide and a kind ofly with simple machine feedback form, realize the self-acting valve that water supply system is dammed and controlled.
For achieving the above object, the present invention---secondary feedback type automatic valve is by valve body, valve seat, spool and cursory composition.Joint at valve body and valve seat is provided with spool.On valve body, there are water intake and water outlet.Between valve seat top and spool, form water pocket chamber, bottom is floating chamber, and it is cursory in floating chamber, to be equipped with.Valve seat is provided with the water port that is communicated with water pocket chamber and floating chamber, and bottom is opening, and the discharge opening of its side is positioned at the top of floating chamber.
Volume of the present invention is little, compact structure, is arranged on container top, safe and reliable, can greatly reduce water overflow faults rate, without very large service hatch.When needing repairing, only need upwards extract pipeline can take out replacing by the present invention, very convenient, has solved the difficult problem of keeping in repair, and without the liquid bleeding off in container, has reduced unnecessary waste.
Four, accompanying drawing explanation
Accompanying drawing is structural representation of the present invention, in figure the Main Current of arrow express liquid to.
Five, embodiment
As shown in the figure, the present invention by valve body 1, valve seat 2, spool and cursory 11 vertical shaft that form to symplex structure.In valve body 1 and the joint of valve seat 2, spool is installed.Valve body 1 is provided with water intake 9 and water outlet 7, and its upper end is inipple, and is provided with water holding ring 12 at periphery.Described spool is positioned at the below of water intake 9, it is comprised of the rubber body 3 with water passage hole and nook closing member 8, nook closing member 8 is " ⊥ " shape, and its long core end passes the water passage hole of rubber body 3, and guarantees that the length of nook closing member 8 should be greater than 13 bottom surfaces, water pocket chamber to the distance of rubber body 3 upper surfaces.At spool periphery, be provided with upper and lower raised ring 4, and be provided with at the corresponding position of valve body 1 and valve seat 2 groove matching, make spool reinforce and seal.Between valve seat 2 tops and spool, form water pocket chamber 13.Said structure forms basic valve body part of the present invention.Valve seat 2 bottoms are floating chamber 10, are equipped with cursory 11 in floating chamber 10.14 places, 14，Qie water port, water port that valve seat 2 is provided with connection water pocket chamber 13 and floating chamber 10 are lower protruding cone structure, and are provided with at cursory 11 top the dash Rubber end 15 coordinating with convex cone under 14 places, water port.Valve seat 2 bottoms are opening 5, and the discharge opening 6 of its side is positioned at the top of floating chamber 10.For preventing that cursory 11 fall, in valve seat bottom, be provided with block (or jackscrew) 16.Above structure forms secondary feedback control part of the present invention.
The present invention is arranged on the pipeline of container top, by the joint on valve body, be connected with feedwater piping, ducted liquid is flowed into by water intake 9, and wherein major part is flowed out by water outlet 7, rush at water holding ring 12, under the barrier effect of water holding ring 12, freely fall in lower reservoir.Another fraction flows into water pocket chamber 13 by the water passage hole in rubber body 3, then 14 flows into floating chambers 10 through water port, finally from valve seat 2, is flowing out and is falling in container with cursory 11 gap and weep hole 6.When liquid in container surpasses the height of valve seat 2 bottoms, liquid level drives built-in cursory 11 floatings of valve seat 2, until cursory 11 dash Rubber end 15 seals water port 14, the interior liquid in water pocket chamber 13 cannot be discharged.At this moment liquid continues 13 inflows to water pocket chamber by the water passage hole in rubber body 3, and the liquid that enters water pocket chamber 13 is more and more, the rubber body 3 on 13 tops, water pocket chamber is upwards expanded, until the water intake of valve body 19 is sealed.This has just completed the closing process of self-acting valve, and the present invention enters automatic closed condition.
When liquid in container reduces, liquid level declines and drives cursory 11 of valve seat 2 to decline, and inlet 14 is opened, and the interior liquid in water pocket chamber 13 flows out, and makes rubber body 3 retractions, and ducted liquid flows in valve body again, makes this valve enter automatic opening state.
Said process moves in circles, and has realized the control of damming to various liquid-containers.
The present invention is applicable to water container, thin oil container, and a lot of fields such as the organic container of low-viscosity, are suitable for extensive popularization.
