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 make the field, be specifically related to a kind of secondary feedback-type self-acting valve that various liquid-containers dam and control that is used for.
Two, background technique
At present, the self water feeding valve of most liquid container all is to adopt cursory drive lever transmission moment, compresses water outlet and realizes automatic-diversion closure control.This self-acting valve need be installed in the side or the below of container, will leave very big service hatch when mounted above container, and in when maintenance, the liquid medium in the container need be bled off, and brings inconvenience and wastes.Adopt the water supply system of such self-acting valve,, cause the waste of manpower because water overflow faults rate height often needs to send the special messenger to manage.And adopt advanced electronic signal feedback control, and though can realize stable self water feeding, reduce water overflow faults rate, its cost height, expense is big and can't solve the difficult problem of maintenance.
Three, summary of the invention
The purpose of this invention is to provide a kind of self-acting valve that dams and control with simple machine feedback form realization water supply system.
For achieving the above object, the present invention---secondary feedback-type self-acting valve is by valve body, valve seat, spool and cursory the composition.Joint at valve body and valve seat is equipped with spool.Water intake and water outlet are arranged on the valve body.Form the water pocket chamber between valve seat top and the spool, the bottom is a floating chamber, and it is cursory to be equipped with in the floating chamber.Valve seat is provided with the water port that is communicated with water pocket chamber and floating chamber, and the bottom is an opening, and the discharge opening of its side is positioned at the top of floating chamber.
Little, the compact structure of volume of the present invention is installed in the container top, and is safe and reliable, can greatly reduce water overflow faults rate, need not very big service hatch.When needing repairing, only need upwards extract pipeline can take out replacing with the present invention, very convenient, has solved the difficult problem of maintenance, and need not to bleed off the liquid in the container, has reduced unnecessary waste.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention, the main flow direction of arrow express liquid among the figure.
Five, embodiment
As shown in the figure, the present invention by valve body 1, valve seat 2, spool and cursory 11 vertical shaft of forming to symplex structure.Joint at valve body 1 and valve seat 2 is equipped with spool.Valve body 1 is provided with water intake 9 and water outlet 7, and its upper end is an inipple, and is provided with water holding ring 12 at periphery.Described spool is positioned at the below of water intake 9, it is made up of the rubber body 3 and the nook closing member 8 of band water passage hole, 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 the distance of 13 bottom surfaces, water pocket chamber to rubber body 3 upper surfaces.Be provided with upper and lower raised ring 4 at the spool periphery, and be provided with the groove that matches, make spool reinforce and seal at the corresponding position of valve body 1 and valve seat 2.Form water pocket chamber 13 between valve seat 2 tops and the spool.Said structure constitutes basic valve body part of the present invention.Valve seat 2 bottoms are floating chamber 10, are equipped with cursory 11 in the floating chamber 10.Valve seat 2 is provided with the water port 14 that is communicated with water pocket chamber 13 and floating chamber 10, and 14 places, water port are protruding cone structure down, and is provided with the dash Rubber end 15 that cooperates with convex cone under 14 places, water port at cursory 11 top.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, be provided with block (or jackscrew) 16 in the valve seat bottom.Above structure constitutes secondary feedback control part of the present invention.
The present invention is installed on the pipeline of container top, be connected with feedwater piping by the joint on the valve body, ducted liquid is flowed into by water intake 9, and is wherein most of by water outlet 7 outflows, rush at water holding ring 12, under the barrier effect of water holding ring 12, freely fall in the lower reservoir.Other flows into water pocket chamber 13 by the water passage hole on the rubber body 3 by fraction, and the 14 inflow floating chambers 10 through the water port fall in the container in slit and weep hole 6 outflows from valve seat 2 and cursory 11 at last again.When liquid in container surpassed the height of valve seat 2 bottoms, liquid level drove valve seat 2 built-in cursory 11 come-ups, seals water port 14 until cursory 11 dash Rubber end 15, and water pocket chamber 13 interior liquid can't be discharged.At this moment liquid continues to flow into to water pocket chamber 13 by the water passage hole on the rubber body 3, and the liquid that enters water pocket chamber 13 is more and more, makes the rubber body 3 on 13 tops, water pocket chamber upwards expand, up to the water intake 9 of valve body 1 is sealed.This has just finished the pass closed procedure of self-acting valve, and the present invention enters automatic closed condition.
When liquid in container reduced, liquid level descended and drives cursory 11 declines of valve seat 2, and inlet 14 is opened, and liquid flow out in the water pocket chamber 13, make rubber body 3 retractions, and ducted liquid flows in the 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, the thin oil container, and a lot of fields such as the organic container of low-viscosity are suitable for extensive popularization.
