Description
Technical field
The utility model relates to a kind of gas water-heater field, particularly a kind of voltage stabilizing spool of gas water-heater water regulating valve.
Background technique
Gas water-heater requires in certain scope intake pressure and pressure surge, thereby water regulating valve must be set at feed-water end, at present, water regulating valve is generally regulated with voltage stabilizing two-part by the water yield and is formed, wherein voltage stabilizing partly comprises valve body, valve seat and spool, valve seat is positioned at valve body, and spool is positioned at valve seat, spool hollow, the following core of spool has by two tapers up and down and fastens the flying saucer bodies that form, and the middle core of spool has the taper of evagination, and described flying saucer body and taper can form sealing with the inwall of valve seat corresponding part respectively, the upper end of spool is the voltage stabilizing dish, the side of voltage stabilizing dish has groove, is embedded with the O RunddichtringO in it, with the inwall formation sealing of valve body, spool is under the voltage stabilizing dish, position on the taper has by-pass hole, and connects with the center hole of spool; Pressure-stabilizing spring is set in outside the spool top on one, and its upper end offsets with the voltage stabilizing dish, and the upper-end surface of its lower end and valve seat offsets; Once pressure-stabilizing spring is arranged between the bottom of the bottom of spool and valve seat; Water inlet divides two-way: the first via is main water route, the current that distribute from water yield adjusting portion, a part is the seal clearance between core taper and the valve base inner wall in spool, flow out from the water port from the valve seat perisporium, another part is through the by-pass hole on spool top, flow out from the center hole of spool bottom, through the flying saucer body of core under the spool and the seal clearance between the valve base inner wall, flow out the water port from the valve seat perisporium at last; The second the tunnel is the pressure-sensitive water route, goes into from the center spool orifice flow of voltage stabilizing dish end face, flows out from the center hole of spool bottom, and through the flying saucer body of core under the spool and the seal clearance between the valve base inner wall, flow out the water port from the valve seat perisporium at last.Its principle of stabilized voltage is: when hydraulic pressure diminishes, the voltage stabilizing dish moves up under the effect of upper and lower pressure-stabilizing spring, at this moment, the flying saucer body of core and the seal clearance between the valve base inner wall all become big under seal clearance in the spool between core taper and the valve base inner wall and the spool, inflow is increased, form new balance; When hydraulic pressure becomes big, the voltage stabilizing dish overcomes upper and lower pressure-stabilizing spring under the water flow pressure effect resistance moves down, at this moment, the flying saucer body of core and the seal clearance between the valve base inner wall all diminish under seal clearance in the spool between core taper and the valve base inner wall and the spool, inflow is reduced, form new balance.
Yet, the face area (promptly being subjected to the hydraulic pressure area) of voltage stabilizing dish is 15～18 with the ratio of the section area (being the intake tunnel section area) of upper end, center spool hole in the spool of existing voltage stabilizing part, show through practice, its voltage regulation result is still not ideal enough, this is requiring in the more strict digital thermostat water heater particularly outstanding to intake pressure, in addition, the voltage stabilizing dish is thinner in the spool of existing voltage stabilizing part, therefore the diameter of section that is embedded the O type circle on it is about 1.8mm, it cooperates surface of contact big inadequately with valve interior wall, thereby bearing capacity is not enough, and the intake pressure adjustable extent is big inadequately.But, if strengthen the thickness of voltage stabilizing dish simply, certainly will change the pressure-stabilizing spring under it, the debugging of whole balance sysmte just need be carried out again, and this need expend great amount of manpower and time.
Summary of the invention
Technical problem to be solved in the utility model is the voltage stabilizing spool that a kind of novel gas water-heater water regulating valve is provided at above-mentioned prior art present situation, after using this voltage stabilizing spool, water regulating valve is faster to the water pressure fluctuations induction, voltage stabilizing is more quick, and the intake pressure adjustable extent is also bigger.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the voltage stabilizing spool of gas water-heater water regulating valve is bottom-up to have following core, middle core and voltage stabilizing dish, the side of voltage stabilizing dish has groove, be embedded with the O RunddichtringO in it, the face area that it is characterized in that described voltage stabilizing dish is 19～22 with the ratio of the section area of upper end, center spool hole.
The section radius of described O RunddichtringO is good with 2.2mm～2.8mm, is best with 2.65mm.
Described voltage stabilizing dish lower end surface has an annular groove, supplies the upper end of pressure-stabilizing spring to be embedded wherein.
Compared with prior art, voltage stabilizing dish of the present utility model be subjected to the hydraulic pressure area bigger with the ratio of intake tunnel section area, thereby faster to water pressure fluctuations induction, voltage stabilizing is more quick, the intake pressure adjustable extent is also bigger; And bigger sealing contact surface will be arranged between the O RunddichtringO of large-section radius and the valve interior wall, can bear bigger hydraulic pressure, thereby make the intake pressure adjustable extent bigger; On the other hand, by offering annular groove in the lower end surface of voltage stabilizing dish, the upper end of pressure-stabilizing spring is embedded wherein, thereby need not to change original pressure-stabilizing spring, the debugging of whole balance sysmte also just will not be carried out again, thereby saves great amount of manpower and time.
