Abstract
The utility model relates to a conical forward closing and backward opening floating ball valve which is a valve device, belonging to the technical field of liquid level control. The closing direction of a valve core of the valve and aa water flow direction are the same, and the opening direction and the water flow direction are opposite. A binding surface of the valve core and a valve nozzle is similar to be conical. The utility model has the advantages of simple structure and convenient installation. The cost of the utility model is the same as the cost of an ordinary floating ball valve which is widely used at present. Compared with the ordinary floating ball valve which is widely used at present, the utility model has the advantages of higher pressure resistance, tight closing and good anti-overflow water.
Description
The utility model is a kind of valve arrangement, belongs to the technical field of liquid level control.
Float valve is widely adopted in the liquid level control of water tank and water pool at present, but a lot of long-term spilling water of water tank and water pool causes certain water resource waste, and its main cause is because these float valves are not closed completely.Also some novel floating-ball valve can address the above problem, but complex structure, selling at exorbitant prices, thereby can not get being extensive use of.
The purpose of this utility model just provides a kind of simple in structure, easy for installation, cost maintains an equal level with the common float valve that is widely adopted at present, and can solve effectively that common float valve is not closed completely or ball float damage etc. causes the wimblelike type forward closing ﹠ backward opening float valve of water tank and water pool hydraulic overflow problem.
The purpose of this utility model is achieved in that and on the basis of original float valve basic building block spool is located between valve seat and the valve nozzle, and spool and valve nozzle inner side surface are made wimblelike type.Make the spool Parallel to the flow direction close, opening direction is opposite with water (flow) direction, and the flowing water passage is the gradual change smooth form, is difficult for the deposition foreign material.
Fig. 1 is a structure sketch of the present utility model.
1. ball floats, 2. connecting rods, 3. valve nozzles, 4. spools, 5. valve seats, 6. supports among the figure
Wherein, ball float (1) and spool (4) connect together by connecting rod (2).Valve seat (5) links to each other with intake pipe.Spool (4) is located between valve seat (5) and the valve nozzle (3), and spool (4) is similar to tapered, and valve nozzle (3) internal surface also is similar to tapered.When in the water tank (pond) when anhydrous, because the effect of gravity, ball float (1) pushes away valve nozzle (3) by connecting rod (2) with spool (4), and the passage that water passes through between spool (4) and the valve nozzle (3) flows to water tank (pond).When ball float (1) rises to the highest water level place along with water tank (pond) middle water level, ball float (1) is pushed into valve nozzle (3) by connecting rod (2) with spool (4) thereby locates to make spool (4) outer side surface and valve nozzle (3) inner side surface fits tightly, played the effect of closing float valve, owing to close along water (flow) direction, so hydraulic pressure is big more, close tightly more.When ball float (1) or connecting rod (2) damage, spool (4) will be adjacent to valve nozzle (3) under the effect of waterpower, thereby can prevent the water tank and water pool spilling water effectively.Wherein, according to the orientation (sidewall of water tank and water pool, top board, base plate) that float valve seat (5) is installed, connecting rod (2) can be done corresponding adjustment.It is tapered rubber sleeve that valve nozzle (3) locates to install internal surface, and the tapered flowing water that makes located of valve nozzle (3) goes out the gradual change smooth form of interruption-forming transition in a word, is difficult for producing incrusted deposit.Valve seat (5) locates to install filter screen, reduces the possibility that valve nozzle (3) stops up.
It is simple, easy for installation to the utlity model has former common floating ball valve structure, the advantage that valency is low, and compared with the withstand voltage height of the latter, Close tightly, anti-overflow water-based is good.
Claims (2)
1, a kind of float valve that is used for liquid level control, mainly by ball float, connecting rod, valve nozzle, spool, valve seat, support is formed, and it is characterized in that: spool is located between valve seat and the valve nozzle.
2, according to claim 1 described float valve, it is characterized in that: spool is similar to tapered, and the valve nozzle inboard is similar to tapered.
