Abstract
The utility model relates to a water level valve, which belongs to the valve technology. The water level valve (1) is arranged between a water supply and drain hole (16) and a water supply and drain pipe (17) which are arranged at the bottom of a water tank (15) of a solar water heater. When the water tank is full of water, an overflow hole (5) is tightly pressed by a circular plate (7) under the combined action of the water pressure corresponding to the water level and the water supply pressure, and then the utility model stops supplying the water. When the utility model drains the water, the water supply pressure disappears, and water in the water tank can be drained by gravity. A water drain pipe can be omitted, and the water tank has no change. The utility model has the advantages of convenient use.
Description
Need open indoor cold valves tap water on roof tank during water on the conventional solar boilers water tank.After water was full, water was introduced indoor releasing through the water tank drain pipe, and the user need in time close cold valves in view of the above, otherwise will waste water, and the user relatively worries about.
A kind of method of utilizing the electric water level gauge control electromagnetic valve to close is arranged.
The utility model purpose provides a kind of water level valve, utilizes pairing hydraulic pressure of cistern water level and last hydraulic pressure acting in conjunction to close, its not electricity consumption and save drain pipe.
The utility model is achieved in that water level valve has two chambeies---hyperbaric chamber and low-pressure cavity, between separate with wall, the appropriate location has the suitable flowing hole of diameter on the wall, the hyperbaric chamber side has a circular metal plate that pivots on the wall, can cover flowing hole according to gravity.The low-pressure cavity outer wall is fixed a level sensor, and it is the Seal cage that an oblateness has suction port, and the chamber simultaneously is to cause drum or flat rubber membrane by air pressure, and another side has a tracheae to stretch into the low-pressure cavity bottom, in order to visit the side water level.Have a dowel bar one end to be fixed in the rubber membrane circle centre position and to pass Seal cage, the other end is propped plectane and is opened a certain angle.
Water level valve low-pressure cavity and water tank bottom join at the mouth of a river up and down, and hyperbaric chamber and upper and lower conduit join.
Open indoor cold valves, tap water is through upper and lower conduit, hyperbaric chamber, flowing hole, low-pressure cavity, the mouth of a river flows into water tank up and down, and along with water level raises, hydraulic pressure increases, air is gradually reduced and causes rubber membrane to be heaved in the tracheae, the drive dowel bar moves and is tending towards breaking away from plectane, and plectane is tending towards covering flowing hole according to gravity, and water thoroughly disengages when full, so plectane covers flowing hole naturally, it compresses last hydraulic pressure body and stops to go up water.
During following water, open indoor water valve, last hydraulic pressure disappears, and plectane is in and covers flowing hole but relaxation state, in the water tank hot water according to the gravity reversal through the mouth of a river, low-pressure cavity, flowing hole, hyperbaric chamber, upper and lower conduit flow into indoor up and down.
The utility model is provided by following examples and accompanying drawing.
Accompanying drawing is a kind of water level valve generalized section that proposes according to the utility model.
Describe working principle of the present utility model and working condition in detail according to accompanying drawing below.
Water level valve (1) comprises hyperbaric chamber (2) and low-pressure cavity (3), between wall (4) is arranged, on open flowing hole (5) and plectane (7) around axle (6) rotation arranged, it can cover flowing hole (5).Level sensor (8) is done together with low-pressure cavity (3), and its one side is rubber membrane (9), and another side has a tracheae (13) to visit to low-pressure cavity (3) bottom.The center of circle (10) that dowel bar (11) one ends are fixed in rubber pattern (9) is located, and the other end jack-up plectane (7) for guaranteeing the sealing of Seal cage (12) in dowel bar (11) moving process, adds one and can stretch place rubber bag tank (14).Low-pressure cavity (3) is joined at the mouth of a river (16) up and down with water tank (15) bottom.Hyperbaric chamber (2) joins with upper and lower conduit (17).
Open indoor cold valves, tap water through upper and lower conduit (17), hyperbaric chamber (2), flowing hole (5), low-pressure cavity (3), up and down the mouth of a river (16) flow into water tank (15), along with being gradually reduced, the interior air of water level rising tracheae (13) cause rubber membrane (9) to be heaved, pulling dowel bar (11) moves right, be tending towards breaking away from plectane (7), it is tending towards covering flowing hole (5) according to gravity, dowel bar (11) disengages with plectane (7) when designing waterborne expiring, it covers discharge orifice (5) naturally, last water hydraulic pressure compresses it, stops to go up water.
Open indoor water valve, last water hydraulic pressure disappears, and plectane (7) is in relaxation state, and the mouth of a river (16), low-pressure cavity (3), flowing hole (5), hyperbaric chamber (2), upper and lower conduit (17) flow into indoor the interior hot water of water tank (15) up and down by gravity reversal's warp.
During the interior drawdown of water tank (15), tracheae (13) internal air pressure reduces gradually, and rubber membrane (9) is flat gradually, and dowel bar (11) is moved to the left down, and jack-up plectane (7) is prepared for going up water next time.
Claims (1)
1. a kind of water level valve of the cistern water level of control when being used for water on the water-heater water tank mainly is made up of hyperbaric chamber (2), low-pressure cavity (3), level sensor (8), it is characterized in that:
Water level valve (1) is divided into hyperbaric chamber (2) and low-pressure cavity (3) by wall (4), has flowing hole (5) on its wall (4), and is equipped with around axle (6), and rotatable plectane (7) is through being connected on the wall (4) around axle (6);
Level sensor (8) is done together with low-pressure cavity (3), its one side is rubber membrane (9), be sealedly connected on low-pressure cavity (3) one ends, the other end has a tracheae (13) to visit to low-pressure cavity (3) bottom, the center of circle (10) that dowel bar (11) one ends are fixed in rubber membrane (9) is located, the other end jack-up plectane (7) is equipped with telescopic rubber capsule (14) on dowel bar (11);
Low-pressure cavity (3) is connected at the mouth of a river (16) up and down with water tank (15) bottom, and hyperbaric chamber (2) is connected with upper and lower conduit (17).
