CN2245143Y - Storage liquid automatic control valve - Google Patents

Abstract

The utility model relates to a storage liquid automatic control valve. The existing liquid storage tank needs providing a water inlet and a water outlet, which increases the usage quantity of pipe elements of a valve and makes a liquid storage water supply pipeline and an outer water supply user pipeline mutually separated, so the existing liquid storage tank is inconvenient in use. The valve body is provided with a water supply opening which is normally opened and a liquid storage opening. A valve opening is arranged between the liquid storage opening and the water supply opening. One end of a traction rod which is penetrated through the liquid storage opening is connected with a float. The other end is connected with a moving valve core between the valve opening and the water supply opening. The valve is adopted, which makes the liquid storage tank opened one opening namely, reduces the cost of a liquid storage water supply system and simultaneously uses the same user pipeline with outer water supply to supply water. The utility model has the advantage of convenient use. The utility model can prevent a water running phenomenon caused by the stop of water supply.

Description

The liquid storage internally piloted valve

The utility model belongs to a kind of liquid storage control valve.

When water system is cut off the water supply; people often need use the water in the liquid tank; existing liquid tank is normally established water inlet and two mouths of a river of water outlet; each mouth of a river all will add control valve; trouble not only is installed; increased valve; the consumption of pipe fitting; improved the cost of supply channel; and because the supply channel of liquid tank and the outer at ordinary times user's pipeline that supplies water are each self-separations; the user will use the supply channel of liquid tank instead when cutting off the water supply; so not only may make the quantity of water-supplying mouth; the place is restricted, and face and people regular meeting cause " metalling run out " phenomenon when recovering outer water supply because of changing the break-make situation that outer water supply user pipeline water tap has been neglected in the water-supplying mouth.

The utility model aims to provide a kind of liquid storage internally piloted valve, this valve can make liquid tank obtain enough water yields from user's pipeline when the water system normal water supply, and after storage is completely a certain amount of, promptly close automatically, when water system is cut off the water supply, can make liquid tank pass through original user's pipeline again automatically and supply water, this valve can also be simplified liquid storage supply channel structure simultaneously.

The technological scheme that realizes above-mentioned purpose is: the valve body of the water-supplying mouth that this valve comprises a band liquid storage mouth, often open, it is characterized in that: between described body cavity liquid storage mouth and water-supplying mouth, be provided with valve port, pass a draw-bar or pulling cable in the liquid storage mouth passage, draw-bar or the pulling cable end outside its valve body is connected with float, the end in its valve body with between aforesaid valve port and the water-supplying mouth, usually be the branch amorph under the streamflow regime with valve port, when being subjected to, just can be adjacent to the movable spool that valve port seals the liquid storage mouth and link to each other to liquid storage mouth direction tractive force.

Working principle of the present utility model is: this valve liquid storage mouth and the liquid tank that is positioned at this valve top are connected, pass liquid storage mouth passage draw-bar or pulling cable be positioned at the float that the outer end of valve body connects and place water storage box, this valve supply water mouth and water system user pipeline are connected, during the water system normal water supply, outer feed flow is promptly through the water-supplying mouth, the liquid storage mouth enters liquid tank, the water yield rises to certain water level in the case, float drive draw-bar with the movable spool tension in the valve body from the water-supplying mouth one side block valve port and close the liquid storage mouth, this moment, spool was in stable closed condition under float tractive force and the outer pressure of supply water effect consistent with the spool closing direction.When water system was cut off the water supply, outer pressure of supply water was reduced to a certain degree or is disappeared, and movable spool promptly resets, and the liquid storage mouth is opened, and the water in the liquid tank flows into user's pipeline by the valve body water-supplying mouth.When recovering outer water supply, this valve can make the automatic epipodium of liquid tank cut out behind certain water gaging again.

Adopt the utility model to make the liquid tank control valve, liquid tank is only opened a mouth of a river and is got final product, not only reduced valve, the pipe fitting consumption, simplified pipeline structure, easy for installation, reduced liquid storage water system cost, and can make liquid storage adopt identical user's pipeline to supply water with outer water supply, when cutting off the water supply, the user can obtain back the liquid storage of confession from former water-supplying mouth, that is to say, outer water supply can automatically switch and adopt the same pipeline mouth of a river to supply water with liquid storage, the user is formed a uninterrupted watering, not only easy to use, and can avoid the user when cutting off the water supply, to open tap, cause the problem of " metalling run out " when coming water.This liquid storage internally piloted valve can not only be used for water storage system, also can be used for the liquid storage control of multiple fluid.

Embodiment 1

The sidewall position at valve body 1 is opened in this routine water-supplying mouth 2, liquid storage mouth 5 is opened at the valve body top, pulling cable 6 passes liquid storage mouth passage, its upper end is connected with float 8, in valve body valve port and movable spool between the water-supplying mouth be an end be hinged in the body cavity water-supplying mouth over against sidewall position, the lever valve 3 that an end links to each other with the pulling cable lower end and tilts below the water-supplying mouth.

When this example was in opening state, the end that the lever valve links to each other with pulling cable under action of gravity was positioned at the valve pocket bottom, and when the liquid tank water level rose to the control height, pulling cable was strained by float, promptly drove the lever valve and blocked valve port sealing liquid storage mouth.

Embodiment 2

Open in the valve body bottom this routine water-supplying mouth 9, liquid storage mouth 14 is opened at the valve body top, draw-bar 13 passes liquid storage mouth passage, its upper end is connected with float, is connected in the valve port in valve body of its lower end and the movable spool between the water-supplying mouth and is one and held in the palm in being positioned at the spherical valve core 11 that the endoceliac bearing 10 of valve ends, moves upward and can seal valve port 12 downwards.
