Abstract
The utility model relates to a kind of hydraulic pressure descaling type heating water boiler automatic water compensating valve, belongs to valve manufacture industry technology field.Valve is made up of valve body, spool, silicagel pad, adverse current cover, screw, ball float, connecting rod, pin.Illustrate that specific works process is in conjunction with Figure of abstract: when heating water boiler has people's water receiving, in water tank, liquid level declines, ball float 6 because of buoyancy reduce decline under earth attraction effect thereupon, movable valve plug 2 is with to rotate around the axis by connecting rod 5, silicagel pad 4 on spool 2 leaves valve port gradually, potable water fills into water tank from valve port, completes automatic water supplement function; Rise gradually along with potable water fills into water tank level, ball float 6 overcomes earth attraction and is with movable valve plug 2 upwards to rotate around the shaft by connecting rod 5 under floating function, the embedded silicagel pad 4 of spool 2 moves closer to and seals up valve port, and water inlet stops, and completes the full automatic closing water cut-off function of water.When the incrustation scale that valve port place, rotating shaft place are formed reaches certain thickness, because valve port rotating shaft place area of contact is very little, incrustation scale along with axis of rotation in phase mutual friction loosen, water inlet moment current rush at rotating shaft place under valve port is ejected in the effect of blocking of adverse current cover at a high speed, the incrustation scale loosened is washed immediately, incrustation scale cannot be retained, complete the function utilizing hydraulic pressure automatic desludging.
Description
Technical field
The utility model relates to a kind of hydraulic pressure descaling type heating water boiler automatic water compensating valve, belongs to valve manufacture industry technology field.
Background technique
The existing heating water boiler float valve be widely used is like this work: when water tank inner horizontal be reduced to ball float buoyancy be not enough to support ball float self gravitation time, under earth attraction effect, ball float is descending; The valve port on valve body is left with ovable valve stem, spool, supply water and fill into water tank from valve port, along with the continuous rising of water tank inner horizontal, hollow float slowly floats and is with ovable valve stem spool to seal valve port gradually under buoyancy of water effect, when water supply pressure in valve port place is with time consistent from float valve bar pressure on spool cross section, current are blocked, and stop moisturizing.Said process is repeated when water level declines again in water tank.Because China region is wide, many areas belong to hard water matter area, and heating water boiler normal working temperature is at about 100 DEG C, and 1-3 month, between float valve valve body and spool, space will be filled up by incrustation scale, and valve movable part is malfunctioning.When causing water level decreasing, valve is not opened, can not moisturizing in time, and heating water boiler dry combustion method, burns out heating pipe and Sealing.When water level rises, valve fits badly, and supply water excessive, control apparatus short circuit is burnt, and also has the potential safety hazard of getting an electric shock.Always this perplex the common problem producing, selling and uying tripartite.
Summary of the invention
This hydraulic pressure descaling type heating water boiler automatic water compensating valve emphasis solves hard water matter area incrustation scale and generates and affect problem to the flexibility of valve movable part.Mainly by redesigning valve body, eliminating and easily being affected the tubular conduit between the valve body of flexibility and spool by incrustation scale.It is embedded that seal spool part changes silicagel pad into, prevents from being fallen by high-velocity flow punching while strengthening durability.In addition turning joint is reduced to one.Reduce area of contact by movable axis surface of contact is made arc simultaneously as far as possible.When incrustation scale is generated to certain thickness, because surface of contact is narrow and small, cannot retain, or loosen when rotating shaft activity, be washed out by the high-velocity flow under adverse current cover backflows.Thus realize the function of automatic scale cleaning between joint motion parts.Valve is made to keep the flexibility of movable part, and reliably working, be heating water boiler moisturizing automatically.While providing for user safe and stable operation to ensure, extend heating water boiler working life, significantly reduce heating water boiler maintenance load and maintenance cost.Patent retrieval does not find same or similar invention and model utility design.

Embodiment
The utility model hydraulic pressure descaling type heating water boiler automatic water compensating valve, is made up of valve body, spool, silicagel pad, adverse current cover, screw, ball float, connecting rod, pin.
As shown in Figure 1: on valve body 1, outside thread is in order to connect intake pipe, the arm holder two with pin-and-hole is stretched out below valve body, the valve body of hollow shrinks gradually and forms valve port above arm holder, spool 2 tailing screw flight connects ball float 6 by connecting rod 5, the front arm of spool 2 is connected to form turning shaft structure by pin 8 and valve body 1, the silicagel pad 4 that now spool 2 is embedded is just in time corresponding with valve port position, knee-action band movable valve plug 2 support arm of ball float 6 is turned an angle around valve body 1 by the rotating shaft of pin 8, the folding that silicagel pad 4 on spool 2 is also corresponding to valve port, thus control the break-make of water inlet.Adverse current cover 3 is fixed on valve body 1 by screw 7.
Specific works process has people's water receiving when heating water boiler, in water tank, liquid level declines, ball float 6 because of buoyancy reduce decline under earth attraction effect thereupon, movable valve plug 2 is with to rotate around the axis by connecting rod 5, silicagel pad on spool 2 leaves valve port gradually, potable water fills into water tank from valve port, completes automatic water supplement function.Rise gradually along with potable water fills into water tank level, ball float overcomes earth attraction and is moved closer to by connecting rod 5 with movable valve plug 2 silicagel pad 4 that upwards rotational valve core 2 is embedded around the shaft and seal up valve port under floating function, water inlet stops, and completes the full automatic hold function of water.When the incrustation scale that valve port place, rotating shaft place are formed reaches certain thickness, because valve port rotating shaft place area of contact is very little, incrustation scale along with axis of rotation in phase mutual friction loosen, water inlet moment current rush at rotating shaft place under valve port is ejected in the effect of blocking of adverse current cover at a high speed, the incrustation scale loosened is washed immediately, incrustation scale cannot be retained, complete the function utilizing hydraulic pressure automatic desludging.
