Abstract
The utility model relates to a liquid stabilizing valve which comprises an upper cover, a valve body, a flexible diaphragm, a valve plug, a spring, etc. The utility model is characterized in that the valve body, the flexible diaphragm, etc. form two cavities which are respectively communicated with a liquid inlet and a liquid outlet; the valve plug is positioned on a passage hole between the two cavities. The utility model can stabilize the work pressure, can determine the height of work liquid levels, is mainly used for replacing floating ball water tanks, is especially suitable for solar energy water heaters, etc.
Description
The utility model relates to a kind of liquid stabilizing valve.
At present, the domestic solar water heater is generally based on closing-sunning type, and when mounted, water intake mostly is directly connected in tap water.Because the pressure of tap water is variable at any time, so the pressure in the solar water heater water tank just produces fluctuation in a big way.Especially dull and stereotyped " unification " formula solar water heater, when the pressure of tap water was big, its inflow in this case, was established lowlyer as if relief tube usually greater than water-outlet quantity, and then hot water just overflows from relief tube; If relief tube is established higherly, then tank pressure increases, and makes its damage.For addressing this problem, when solar water heater was installed, have to increase by " floating ball tank " that has promptly controlled fixedly water level with float valve, so that the pressure stability in the solar water heater water tank.But its deficiency is to make its cost increase and make installation complicated.
The purpose of this utility model is to solve above-mentioned deficiency, a kind of liquid stabilizing valve that volume is little to obtain, simple structure also can make the pressure stability in solar water heater water tank or other cistern tool.
For achieving the above object, the utility model makes valve body and flexible membrane etc. constitute two cavitys (I, II) in its structure, and is communicated with liquid inlet and outlet respectively, and valve plug is located on the port hole between two cavitys and with flexible membrane and is linked to each other.In working order down, as long as the work liquid level in the cistern tool (water tank) reaches certain height, its pressure just acts on the cavity II by liquid outlet, comprises flexible membrane.At this moment, the pressure that this flexible membrane bore also reaches certain value, thereby the pulling valve plug is closed it.It is adjusting work liquid level that the another side of this flexible membrane is established a spring, that is the pressure limit in definite cistern tool (water tank).
Elaborate below in conjunction with accompanying drawing: be flexible membrane (7) between valve body (12) and the loam cake (2), the three is fixed together with screw (6), constitutes cavity I and II thus on valve body.Liquid entering hole is communicated with the cavity I, and liquid outlet is communicated with the cavity II, and valve plug (11) is located on the port hole between two cavitys, and links to each other with flexible membrane by valve handle (10).Loam cake (2) is provided with circular cavity, and dust cover (1) is equipped with at the cavity top, and spring capping (3) is housed in the cavity, and gland (8) is equipped with in the upper end of flexible membrane (7), between spring capping (3) and gland (8) spring (4) is housed.In the empty film II that valve body (12) is constituted water diversion disk (13) is housed, liquid inlet joint (14) is equipped with in its lower end.
The utility model has the advantage of both to reach above-mentioned voltage stabilizing purpose that can determine again its work liquid level, in addition, its volume is little, simple structure.
Description of drawings: this figure is a structural portion view of the present utility model.Among the figure: 1 is dust cover, and 2 is loam cake, and 3 is spring capping, and 4 is spring, and 5 is nut, and 6 is screw, 7 is flexible membrane, and 8 is gland, and 9 are pad, and 10 is valve handle, and 11 is valve plug, 12 is valve body, and 13 is water diversion disk, and 14 is liquid inlet joint, and 15 is sealing gasket, and I and II are represented cavity.
Embodiment: spring 4, nut 5, screw 6, pad 9 all adopt standard component, and flexible membrane 7 and sealing gasket 15 adopt elastomeric material, and remaining component is all made by the low-pressure polyethylene plastic injection.
