Abstract
A kind of water Proportional valve for gas water-heater, comprise helical pitch part, shell, spool, spool is provided with valve, characterized by further comprising the conducting element joining with valve, current strike on the inwall of shell and from the space between conducting element and outer casing inner wall and flow out under the guide functions of conducting element, under the little condition of intake pressure high flow capacity, can effectively reduce noise.
Description
Technical field
The utility model relates to a kind of water Proportional valve for gas water-heater.
Background technique
In the prior art, the water Proportional valve structure that gas water-heater is used as shown in Figure 1, cold water enters from water intake, then by the opening between valve port and valve, from water outlet, flow into the heat exchanger of water heater, when being adjusted to small flow, because intake pressure is high, according to hydromechanical theory, the pressure of current is to be directly proportional to the speed of current, therefore current are spouting from exporting by the speed with higher, current become the angle of Fig. 1 dotted line substantially, enter in long narrow water channel, high-velocity flow clashes into tube wall, causes larger noise.For overcoming above-mentioned defect, the water Proportional valve of domestic gas-fired water heater is improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water Proportional valve for gas water-heater, under the little condition of intake pressure high flow capacity, can effectively reduce noise.
The technological scheme that the utility model solves its technical problem employing is: a kind of water Proportional valve for gas water-heater, comprise helical pitch part, shell, spool, spool is provided with valve, also comprise the conducting element joining with valve, the arc shaped surface of indent and the buffering flange joining with arc shaped surface in the middle of described conducting element is provided with, between buffering flange and outer casing inner wall, leave space, current strike on the inwall of shell and flow out from the space between conducting element and outer casing inner wall under the guide functions of conducting element.
Described helical pitch part bottom is provided with locating flange, and locating flange contacts with outer casing inner wall.
The utility model is compared produced beneficial effect with background technique: because the utility model adopts, comprise helical pitch part, shell, spool, spool is provided with valve, also comprise the conducting element joining with valve, current strike on the inwall of shell and the structure flowing out from the space between conducting element and outer casing inner wall under the guide functions of conducting element, under the little condition of intake pressure high flow capacity, can effectively reduce noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of background technique;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the explosive view of Fig. 2;
Fig. 4 is the enlarged view of spool 5 in Fig. 3.
Embodiment
Shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, the present embodiment comprises that stepper motor 1, helical pitch part 3, shell 4, spool 5, spool 5 are provided with valve 6, also comprise the conducting element 7 joining with valve 6, current strike on the inwall of shell 4 and from the space between conducting element 7 and shell 4 inwalls and flow out under the guide functions of conducting element 7.
Particularly, the arc shaped surface 2 of indent and the buffering flange 8 joining with arc shaped surface 2 in the middle of described conducting element 7 is provided with, the arc shaped surface 2 of middle indent is the recessed surface of revolution to spool 5 medial axis, between buffering flange 8 and shell 4 inwalls, leaves space.
As shown in Figure 2, in use, water (flow) direction as shown by arrows, water enters from water Proportional valve water intake, by the space between the valve port in valve 6 and shell 4, flow into, then the arc shaped surface along conducting element 7 middle indents is ejected on buffering flange 8, strike again on the inwall of shell 4, from the space between shell 4 inwalls and buffering flange 8, flow out, the angle of current is the dotted line angle of water export in Fig. 2 substantially, after a series of like this flow direction changes, water flow velocity is reduced, the situation of substantially having eliminated gathering center and spray before entering the heat exchanger of water heater, greatly reduce like this noise causing because of injection water shock waterpipe.When high hydraulic pressure (0.5MPa) small flow (4L/min), it is a kind of vaporific that water base of ejection can become, and can effectively reduce to clash into pipeline and produce noise.
Further, helical pitch part 3 bottoms are provided with locating flange 9, locating flange 9 contacts with shell 4 inwalls, and locating flange 9 is fastened between helical pitch part 3 bottoms and shell 4 inwalls, because spool 5 is enclosed within helical pitch part 3, locating flange 9 is fixed helical pitch part 3 positions, and then can make spool 5 accurate positionings, can, because hydraulic pressure is large, to valve 6, not produce excessive power, cause spool 5 to roll, even secundly.
Evidence, the water heater of same model, when using the water Proportional valve of background technique, the noise producing during high hydraulic pressure (0.5MPa) small flow (4L/min) can be up to 80dB, considerably beyond regulation (≤65dB of standard GB/T 6932-2001); And while using the water Proportional valve after the present embodiment improves, the noise of generation is only 55dB, the utility model has reached the effect of effective reduction noise.
