Abstract
The utility model discloses an automatic water supply valve, which comprises a water inflow base (3), a water outlet base (4), a valve cap (1), a valve body (2), an elastic film (6) and a movable plate (7). The automatic water supply valve is characterized in that the water inflow base (3) is positioned at on one side of the bottom of the valve body (2); the water outlet base (4) is positioned in the middle of the bottom of the valve body (2); an intake tunnel (5) is arranged in the water inflow base (3), the intake tunnel (5) is a tunnel with variable diameters, the diameter of the upper part is big, and the diameter of the lower part is small; a valve core (16) is positioned at the upper part of the intake tunnel (5), the upper part of the valve core (16) is connected to one end of a lever (9), and the other end of the lever (9) is connected to the elastic film (6) and a hanging screw (8) which is arranged on the movable plate (7). The utility model is adopted, thus the water inflow pressure is definite, and the water inflow quantity is constant, and with the change of the water inflow pressure, the position of the automatic water supply valve can be adjusted to maintain the constant water inflow quantity.
Description
Technical field
The utility model relates to a kind of automatic loading water valve.
Background technique
Existing automatic loading water valve is made up of influent base, effluent seat, valve gap, valve body, elastic membrane and mobile plate, be provided with spool in the influent base, spool is connected with valve rod on elastic membrane, the mobile plate, be provided with pressure spring between elastic membrane top and the valve gap, by the default certain influent pressure of pressure spring, when influent pressure changes, the aging water tank water intake that can occur of pressure spring is crossed lowly or too high, water can be excessive sometimes.
Summary of the invention
The utility model provides a kind of influent pressure certain, the automatic loading water valve that inflow is constant, and can adjust the position with the influent pressure change and keep constant inflow.
The utility model is achieved in that the automatic loading water valve, it comprises influent base, effluent seat, valve gap, valve body, elastic membrane and mobile plate, influent base is positioned at valve body bottom one side, and effluent seat is positioned in the middle of the valve body bottom, is provided with intake tunnel in the influent base, intake tunnel is a variable diameter passage, its upper diameter is big, and lower diameter is little, and spool is positioned at the top of intake tunnel, spool top is connected with an end of lever, and the other end of lever connects with the screw that hangs tight that elastic membrane, mobile plate are provided with.
Valve body or valve gap are connected with the horizontal support plate, and screw rod is installed in the far-end of supporting plate, and an end of screw rod is provided with end socket; The lower end that hangs tight screw is provided with boss, has notch with hanging tight the lever end that screw connects, and hangs tight screw and is stuck in the notch, and its boss is positioned at the below of notch.
After adopting as above technological scheme, tank pressure is less than influent pressure when beginning to intake, and the spool that hydraulic pressure upwards backs down in the influent base begins water inlet, the water tank internal pressure increases gradually, when reaching certain value, utilize the water-head of water tank and valve body to produce pressure, upwards act on elastic membrane and mobile plate, spur on the end that hangs tight screw and lever and move, then the other end of lever moves down, and spool moves down in intake tunnel, has blocked the following water intake of intake tunnel, water tank stops into water, realizes automatic loading water.After water tank discharged water, the water-head between water tank and valve body disappeared, and spool moves under influent pressure and the mobile plate action of gravity, and the water intake of intake tunnel is opened automatic water inlet.When influent pressure changes, adjust the relative position between supporting plate and the screw rod, just adjust the relative height of valve body and water tank, can change inflow, can not cause into the water deficiency or intake excessive.

Embodiment
With reference to accompanying drawing, the automatic loading water valve, it mainly is made up of valve gap 1, valve body 2, and influent base 3 is positioned at valve body 2 bottoms one side, and effluent seat 4 is positioned in the middle of valve body 2 bottoms.Be provided with intake tunnel 5 in the influent base 3, intake tunnel 5 is divided into three parts, and the middle part diameter is little, and upper and lower two-part diameter is big, and spool is positioned at the top of intake tunnel 5.Be provided with elastic membrane 6 and mobile plate 7 in the valve body 2, elastic membrane 6 and mobile plate 7 fuse by hanging tight screw 8.With influent base 3 tops is that fulcrum is provided with lever 9, and lever 9 one ends are connected with spool, and the other end flexibly connects with the lower end that hangs tight screw 8.The lower end that hangs tight screw 8 is provided with boss 10, has notch on the lever 9, hangs tight screw 8 and just is stuck in the notch of lever 9, and the below that boss 10 is positioned at notch props up notch.
Be provided with horizontal support plate 11 between effluent seat 4 and the valve body 2, the far-end of supporting plate 11 is provided with screw, and screw rod 12 is through in the screw, and an end of screw rod 12 is provided with end socket 13, and end socket 13 is connected with the overflow hole 15 of water tank 14 during installation.When influent pressure increases, can reduce the height of valve body 2 with respect to overflow hole 15, the pressure of effluent seat 4 sides increases relatively in the valve body 2, keeps certain inflow, can not cause that into water is excessive.
Claims (3)
