Abstract
The utility model relates to a looping float valve. A valve sleeve is sheathed on the outer part of a valve core whose upper end is fixedly connected with a valve seat, and the lower end of the valve sleeve is connected with a float. A connection device is arranged between the valve cover and the valve core. The float valve has the advantages of simple structure, small size, safe utilization, convenient maintenance, low cost, etc., and can be widely popularized and used in domestic automatic water storage devices, liquid storage tanks and oil storage tanks.
Description
The utility model belongs to the valve technology field, relates in particular to the loop type valve by float-operated.
The domestic water-storage device all adopts float to control the water yield that enters in the water tank by the switch of lever control valve as lavatory flushing cistern water inlet valve at present.This Lever type float-controlled valve, complex structure, volume are big, occupy very large space in water tank, keep in repair very inconveniently, leverage becomes by Huang system copper, the spherical float complex manufacturing technology, cost is very high, in actual use, often takes place closely not cause the phenomenon of metalling run out because of valve closing.
The purpose of this utility model is to overcome the shortcoming of Lever type float-controlled valve, provide a kind of simple in structure, cost is low, use loop type float-controlled valve easy to maintenance.
For achieving the above object, the solution that the utility model adopts is: the outside of the spool that is fixedly connected with valve seat on valve pocket is sleeved on, the lower end of valve pocket and a float link, and a coupling arrangement is set between valve pocket and spool.
The axial centre position of the utility model spool is drilled with inlet opening, and outer surface has annular transfusion groove one, is drilled with the transfusion through hole in annular transfusion groove, is drilled with out fluid through-hole at the outer surface of valve pocket.Float of the present utility model is cup-shaped or rectangle or sphere.The coupling arrangement that is provided with between the utility model valve pocket and the spool is spacing coupling nut.
The utility model is compared with the Lever type float valve, have simple in structure, volume is little, safe and reliable, easy to maintenance, low cost and other advantages, can in family expenses automatic water storage device, liquid container, oil storage tank, extensively promote the use of.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model spool.
Fig. 3 is the structural representation of the utility model valve pocket.
In Fig. 1, the upper end of spool 2 and valve seat 1 are fixedly connected, the lower end is sleeved in the valve pocket 4, install a spacing coupling nut 3 and connect with screw threads for fastening with valve pocket 4 tops at boss place on spool 2, valve pocket 4 and spool 2 are combined as a whole, and spacing coupling nut 3 moves up and down along spool 2 with valve pocket 4, when valve pocket 4 moved to extreme lower position, spacing coupling nut 3 of boss and valve pocket 4 above the spool 2 moved down.At the lower end of valve pocket 4 screw 5, float 7 of pad 6 fastening connections.The float of present embodiment is selected the cup-shaped float of the plastics of a mouth down for use, also can select rectangle float or spherical float or other shape float for use.
In Fig. 2, the outer surface of spool 2 has one annular transfusion groove and two road boss, above one boss be used for that the spacing coupling nut 3 of restraint is thrown off with spool 2 and confined liquid flows out outside the valve pocket 4, following boss makes liquid go out the fluid through-hole outflow from valve pocket 4.On the annular transfusion groove inner diameter direction of spool 2, be drilled with two transfusion through holes, be drilled with inlet opening in the axial centre position of spool 2.
In Fig. 3, the outer surface of upper car of valve pocket 4 have that outside thread is used for fasteningly connecting with spacing coupling nut 3, the lower end is drilled with a vent and one connect screw, connecting screw is used for valve pocket 4 and float 7 are combined as a whole, vent is used to get rid of the air of valve pocket bottom, vertically is drilled with four and goes out fluid through-hole on the outer surface diameter direction of valve pocket 4.
Automatically the liquid that holds of present embodiment is to realize like this, as shown in Figure 1, when the liquid level of liquid in the liquid container when float 7 is following, under the action of gravity of float 7 and valve pocket 4, float 7 is moved down into extreme lower position, the annular of spool 2 outer surfaces transfusion groove faces the liquid outlet opening of valve pocket 4, liquid enter, flow through from the shaft orientation liquid feeding hole of spool 2 spool 2 transfusion through hole, annular transfusion groove and valve pocket 4 go out fluid through-hole, flow in the liquid container then.When the liquid level in the liquid container reaches the rim of a cup of cup-shaped float 7, air in the cup-shaped float 7 is sealed, form an airtight space, liquid continues to flow into liquid container, and at this moment cup-shaped float 7 floats, and upwards pushes away valve pocket 4 and moves up, make the defeated groove of annular of spool 2 and the fluid through-hole that goes out of valve pocket 4 stagger, as the position of double dot dash line among the figure, liquid flow path cuts off, and liquid can not flow in the liquid container.
