Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
The improvement of having done with respect to prior art for a better understanding of the present invention, the prior art of below first background technique partly being mentioned 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 the 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 descends, push rod body 131 is fixing by upper O-ring seals 15 with pilot valve 14, bad in the reliability that the top of spring pressure or the larger situation lower push rod of hydraulic pressure body 131 is fixedly connected with, push rod body 131 and pilot valve 14 are broken away from, thereby cause water valve and refrigerator drinking water machine the phenomenon of leaking or dripping to occur.
On the basis of being analyzed based on the problem that existing water valve is existed, 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 with pilot valve 24, is flexibly connected.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, sealing interface 215 is used for realizing being tightly connected of inner casing 211 and Sealing 25 when the disconnection of water valve when push rod body 231 is subject to pushing tow and push rod body 231 reset.
In the present invention, 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 the pressure release effect and improve sealing reliability, simultaneously, the sealing surface of Sealing is upright taper primary sealing area, sealing surface increases greatly in the process of using, 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,, in order to downward elastic force is passed to pilot valve 24, drives pilot valve 24 and pushes and be fitted on inner casing by Sealing 25, realizes the effect of sealing.
