Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
Embodiment 1
The improvement of having done with respect to prior art in order better to understand the utility model, the prior art of first background technique partly being mentioned below detailed analysis in addition.
As shown in Figure 1, under existing water valve utilization, O-ring seals 16 extrusions reach sealing effect, after long-term use, easily cause the wearing and tearing of lower O-ring seals 16, distortion or fold, the cross section of lower O-ring seals 16 can change, sealing effect declines, push rod body 131 is fixing by upper O-ring seals 15 with pilot valve 14, the reliability being fixedly connected with at the top of spring pressure or the larger situation lower push rod of hydraulic pressure body 131 is bad, easily make push rod body 131 and pilot valve 14 depart from, thereby cause water valve and refrigerator drinking water machine to occur the phenomenon of leaking or dripping.
On the basis that problem based on existing water valve is existed is analyzed, the present embodiment has proposed a kind of water valve, and as shown in Figure 2, this water valve comprises a valve body 21, a spring 22, water intaking push rod 23 and a pilot valve 24.Valve body 21 comprises an inner casing 211 and a shell 212.Inner casing 211 forms an inner flow passage 213, and inner casing 211 and shell 212 are around being formed with an outer flow passage 214.
As shown in Fig. 2～3, water intaking push rod 23 comprises a push rod body 231 and a tip-lever support 232.Push rod body 231 stretches in inner flow passage 213, and is flexibly connected with pilot valve 24.The bottom of pilot valve 24 is arranged with a Sealing 25, and the seal 25 is sheathed on described push rod body 231.In addition, the bottom of Sealing 25 is formed with a upright taper primary sealing area, the inner casing 211 of valve body 21 be provided with one with the suitable sealed interface 215 of upright taper primary sealing area, when when sealing interface 215 is subject to pushing tow for realizing push rod body 231, the disconnection of water valve and push rod body 231 reset, inner casing 211 and Sealing 25 is tightly connected.
In the utility model, pilot valve 24 is tightly connected by Sealing 25 with inner casing 211, the bottom of Sealing 25 is formed with a upright taper primary sealing area, inner casing 211 be provided with one with the suitable sealed interface 215 of upright taper primary sealing area, can alleviate hydraulic pressure like this, lower the pressure of water to Sealing 25, thereby reach pressure release effect and improve sealing reliability, simultaneously, the sealing surface of Sealing is upright taper primary sealing area, in the process of using, sealing surface increases greatly, and longer sealing surface effect of the time of use is better.
Wherein, as shown in Figure 2, the two ends of spring 22 are supported under the pressure of between inner casing 211 and tip-lever support 232 respectively, make tip-lever support 232 have the inertia that detaches described outer flow passage 214.Tip-lever support 232 is connected with pilot valve 24 by push rod body 231, to downward elastic force is passed to pilot valve 24, drives pilot valve 24 to push and be fitted on inner casing by Sealing 25, realizes the effect of sealing.
In addition, as shown in Figure 3, sealed interface 215 has a upright taper secondary sealing area.Upright taper secondary sealing area is identical with the tapering of upright taper primary sealing area.While making so upright taper primary sealing area and upright taper secondary sealing area mutually seal, between Sealing 25 and sealed interface 215, gapless, sealing surface increase, sealing reliability and sealing effect are better.
In addition, as shown in Figure 3, push rod body 231 is provided with a boss 233.Sealing 25 is arranged between boss 233 and the bottom of pilot valve 24.Make like this Sealing 25, pilot valve 24 and push rod body 231 shapes in aggregates, improved the sealability between pilot valve 24 and push rod body 231, eradicated the phenomenon that occurs seepage between pilot valve 24 and push rod body 231, can make Sealing 25 depart from sealed interface 215 by pushing tow push rod body 231, thereby cause water valve to disconnect, realized the water intaking performance of refrigerator drinking water machine.
Further, as shown in Figure 3, push rod body 231 runs through pilot valve 24, and push rod body 231 connects with pilot valve 24 affixed by seizing type.Easy to operate like this, the fixedly reliability between push rod body 231 and pilot valve 24 is large, has thoroughly avoided due to spring pressure or the excessive undesirable condition that causes push rod body 231 to come off of hydraulic pressure.
Further, as shown in Figure 3, the top of pilot valve 24 is provided with a draw-in groove 241, the top of push rod body 231 is provided with a shackle member 234, shackle member 234 is arranged in draw-in groove 241, make like this water valve easy to assembly, only need exert oneself a little just push rod body 231 can be fixed in the draw-in groove 241 of pilot valve 24, time saving and energy saving.
The working principle of the water valve of the present embodiment is as follows:
During waiting for water intaking, the two ends of spring 22 are supported respectively between outer surface and tip-lever support 232 under the pressure of inner casing 211, make described tip-lever support 232 there is the inertia that detaches outer flow passage 214, by the interlock of described push rod body 231, this tip-lever support 232 can be passed to pilot valve 24 by downward elastic force, drive pilot valve 24 to omit micromotion downwards, by the mode of squeeze sealing member 25, finally realize the mutual sealing of the upright taper primary sealing area of Sealing 25 and the upright taper secondary sealing area of sealed interface 215, guaranteed between pilot valve 24 and the inner casing 211 of valve body 21 and pilot valve 24 and water intaking push rod 23 push rod body 231 between sealing effect.
During fetching water, user only need press down water intaking lever (not shown), overcome the elastic force of spring 22, tip-lever support 232 is moved upward, can realize the push rod body 231 that links successively, Sealing 25 and pilot valve 24 moves upward, finally realize Sealing 25 and depart from sealed interface 215, potable water slowly flows out.
