(3) summary of the invention
Technical problem to be solved in the utility model is to overcome the particularly above-mentioned deficiency of solar water heater storage water tank water level limited valve of above-mentioned water storage box, and a kind of water storage tank water level limited valve that can make full use of space in the water storage box is provided.
The utility model comprises ball float, connecting rod, the plug of taper, can be installed in the valve body of water storage box, seal ring, plug is fixed on the lower end of connecting rod, ball float is installed in the upper end of connecting rod, the upper end of valve body is a connection mouth, and an axial water port arranged, the circular groove that the axle that hangs down is arranged under the water port, seal ring is installed in the circular groove, the water port is stretched in the lower end of connecting rod, plug is positioned under the seal ring, the outer diameter of plug has an axial water containing chamber greater than the inner diameter of seal ring under the seal ring of valve body, the inner diameter of water containing chamber is greater than the outer diameter of plug, under the valve body water outlet is arranged, it is characterized in that: the ball float sleeve is being set outside ball float, and there are port interlinked with the outside, the barrel distribution through hole of ball float sleeve in ball float sleeve upper end; Distance between valve body connection mouth and the ball float ball top is greater than the height of water storage box, during installation, valve body is installed at the bottom of the water storage box, and the ball float sleeve is installed in bottom, water storage box top and stretches in the water storage box, the extreme higher position of ball float exceeds the water storage box top, and the water level in the water storage box just can reach the water storage box top.
Impact of water is crossed senior general's plug and is rushed at seal ring the water port is sealed when adding water, in the water containing chamber of above-mentioned water storage tank water level limited valve, air guide sleeve is being set, air guide sleeve is glass liner shape, at air guide sleeve distribution through hole, the upper end of air guide sleeve is installed under the circular groove, the inner diameter of air guide sleeve is convenient to plug and is moved up and down in air guide sleeve greater than the outer diameter of plug.
When this water storage tank water level limited valve was installed in water storage box, ball float exceeded water storage box case top, and the water level in the water storage box just can reach the water storage box top, water just can be full of water storage box, can make full use of space in the water storage box, and only just can realize adding the effect of water, water with a conduit pipe, institute takes up space little.The impulse force that air guide sleeve can slow down water is being set, and impact of water is crossed senior general's plug and is rushed at seal ring and seal the water port when avoiding adding water.
