Description
Technical field
The utility model relates to a kind of gas water-heater field, particularly a kind of water regulating valve that is used for gas water-heater.
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 bottom of spool has by two tapers up and down and fastens the flying saucer bodies that form, and the middle part 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, the seal clearance of a part between spool middle part taper and valve base inner wall, 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 spool bottom 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 spool bottom 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 seal clearance between spool middle part taper and the valve base inner wall and the flying saucer body and the seal clearance between the valve base inner wall of spool bottom all become big, 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 seal clearance between spool middle part taper and the valve base inner wall and the flying saucer body of spool bottom and the seal clearance between the valve base inner wall all diminish, inflow is reduced, form new balance.
Yet flying saucer body and the taper of the spool of existing voltage stabilizing part by its evagination is line with sealing between the valve base inner wall and cooperates, referring to Fig. 4, and owing to these two sealings need be finished simultaneously, thereby higher to the requirement on machining accuracy of spool;
On the other hand, the face area (promptly being subjected to the hydraulic pressure area) of voltage stabilizing dish is 15～18 with the ratio of its center hole section area (being the intake tunnel section area) in the spool of existing voltage stabilizing part, show through practice, its voltage regulation result is still not ideal enough, and this is requiring in the more strict digital thermostat water heater particularly outstanding to intake pressure;
Again on the one hand, the voltage stabilizing dish is thinner in the spool of existing voltage stabilizing part, and the diameter of section that therefore is embedded the O type circle on it is about 1.8mm, and 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 last 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

The technical problem that the utility model further will solve provides a kind of, voltage stabilizing quicker, adjustable in pressure scope bigger modulating valve of being used for the gas water-heater water yield faster to water pressure fluctuations induction.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this voltage stabilizing that is used for the water regulating valve of gas water-heater partly comprises valve body, valve seat and spool, valve seat is positioned at valve body, and spool is positioned at valve seat, the bottom of spool has the flying saucer body of evagination, its top has the taper of evagination, its upper end is the voltage stabilizing dish, the side of voltage stabilizing dish has groove, be embedded with the O RunddichtringO in it, described flying saucer body and taper can form sealing with the inwall of valve seat corresponding part respectively, and, 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, the flying saucer body that it is characterized in that described spool is oblate cylindricality in its outer most edge portion, and it cooperates with the face that is sealed between the corresponding valve base inner wall.
The face area of the voltage stabilizing dish of described spool is good with the ratio of the section area of upper end, center spool hole with 19～22, and the section radius of described O RunddichtringO is good with 2.2mm～2.8mm, is best with 2.65mm; At this moment, described voltage stabilizing dish lower end surface can have an annular groove, is embedded wherein for described upper end of going up pressure-stabilizing spring.
Compared with prior art, the utility model since the flying saucer shape portion of spool cooperate with the face of being sealed between the valve seat, even thereby certain tolerance arranged, also can guarantee and spool tapered portion and valve seat between sealing keep synchronously, thereby reduce requirement on machining accuracy to spool, be more convenient for making, and be subjected to the hydraulic pressure area and the ratio of intake tunnel section area of voltage stabilizing dish increase to 19～22, can make modulating valve faster to the water pressure fluctuations induction, voltage stabilizing is more quick, and the intake pressure adjustable extent is also bigger; Moreover, by offering annular groove, the upper end of pressure-stabilizing spring being embedded wherein, thereby need not to change original pressure-stabilizing spring of going up in the lower end surface of voltage stabilizing dish, the debugging of whole balance sysmte also just will not be carried out again, thereby saves great amount of manpower and time.
