Description
技术领域Technical field
本发明涉及一种水龙头阀门,尤其涉及一种不受水质影响的延时自关龙头。The invention relates to a faucet valve, in particular to a delayed self-closing faucet which is not affected by water quality.
背景技术Background technique
在当代,为了满足人们越来越高的卫生要求,在公共场合的卫生间大多安装红外感应水龙头或者延时自关水龙头,这两种水龙头的一个共同之处是人们在洗手后不需要再接触水龙头即可实现水龙头的自动关闭。其中,延时自关水龙头采用弹簧装置实现自关复位,并且依靠负压变化率实现水龙头关闭时间的调节。In the contemporary era, in order to meet the increasing hygiene requirements of people, most of the toilets in public places are equipped with infrared sensor faucets or time-delayed faucets. One of the common features of these two types of faucets is that people do not need to touch the faucet after washing their hands. The automatic closing of the faucet is possible. Among them, the self-closing faucet adopts a spring device to realize self-closing reset, and the faucet closing time is adjusted by the negative pressure change rate.
如图1所示,现有的延时自关水龙头的阀门一般包括阀体1和阀芯2,阀体1下部设置有将阀体1和进水管分隔的负压腔3,负压腔3上部设置有连接进水管的进水孔4,阀体1上设置有出水孔5,阀体1上还设置有由阀芯2控制打开的通水孔6,通水孔6打开时连通出水孔5和进水孔4;阀芯2从中部穿过阀体1,阀芯2顶端设置有按压开关7,阀芯2下端连接设置在负压腔3内的活塞8,由阀芯2带动活塞8在负压腔3内作活塞运动,活塞8周边设置有单向密封圈9,活塞8底部设置有大小可调节的负压调节孔16;阀体1内设置有使阀芯2复位的弹簧装置11。使用前,通水孔6封闭,当对按压开关7施加压力使活塞8向负压腔3内部移动时,通水孔6打开,水通过进水孔4后从出水孔5流出,同时负压腔3内的水通过单向密封圈9排出;当活塞8在弹簧装置11带动下返回时,使活塞8和负压腔3之间形成负压,进水孔4部分的水通过负压调节孔16进入活塞8与负压腔3之间,活塞8缓慢复位,其复位的时间可以通过调节负压调节孔16的大小设定,当活塞8回到原来位置时,堵塞通水孔6,水龙头自动关闭。As shown in FIG. 1 , the valve of the existing time delay self-closing faucet generally comprises a valve body 1 and a valve core 2, and a lower pressure chamber 3 separating the valve body 1 and the water inlet pipe is disposed at a lower portion of the valve body 1, and the negative pressure chamber 3 is provided. The upper part is provided with a water inlet hole 4 for connecting the inlet pipe, the valve body 1 is provided with a water outlet hole 5, and the valve body 1 is further provided with a water-passing hole 6 controlled by the valve core 2, and the water-passing hole 6 is connected to open the water hole. 5 and the water inlet hole 4; the valve core 2 passes through the valve body 1 from the middle, the top of the valve core 2 is provided with a push switch 7, the lower end of the valve core 2 is connected to the piston 8 disposed in the negative pressure chamber 3, and the piston 2 drives the piston 8 is a piston movement in the negative pressure chamber 3, a unidirectional seal ring 9 is arranged around the piston 8, and a negative pressure adjustment hole 16 of adjustable size is arranged at the bottom of the piston 8; a spring for resetting the valve core 2 is arranged in the valve body 1 Device 11. Before use, the water-passing hole 6 is closed. When the pressure is applied to the push switch 7 to move the piston 8 to the inside of the negative pressure chamber 3, the water-passing hole 6 is opened, and the water passes through the water-inlet hole 4 and flows out from the water outlet hole 5 while being under negative pressure. The water in the chamber 3 is discharged through the one-way sealing ring 9; when the piston 8 is returned by the spring device 11, a negative pressure is formed between the piston 8 and the negative pressure chamber 3, and the water in the water inlet hole 4 is adjusted by the negative pressure. The hole 16 enters between the piston 8 and the negative pressure chamber 3, and the piston 8 is slowly reset. The resetting time can be set by adjusting the size of the negative pressure adjusting hole 16, and when the piston 8 returns to the original position, the water passing hole 6 is blocked. The faucet is automatically closed.
采用上述阀门的水龙头实现了延时自动关闭的功能,但存在使用寿命短的缺点:1、水中的杂质会堵塞负压调节孔16,从而使负压腔3内的负压不能释放,导致活塞8很长时间不能复位,使延时自关功能失效;2、当活塞8复位的时候,水中的杂质也可能会和单向密封圈9发生摩擦,长时间的摩擦可能使单向密封圈9磨损而失效,导致负压腔3内部不能形成负压,活塞8在按下后会快速复位,延时自关功能失效;3、单向密封圈9长期浸泡在水中,也容易影响其密封性能,从而使阀门失效。The faucet adopting the above valve realizes the function of automatically closing the time delay, but has the disadvantages of short service life: 1. The impurities in the water block the negative pressure regulating hole 16, so that the negative pressure in the negative pressure chamber 3 cannot be released, resulting in the piston 8 can not be reset for a long time, so that the delay self-closing function is invalid; 2. When the piston 8 is reset, the impurities in the water may also rub against the one-way sealing ring 9, and the long-term friction may cause the one-way sealing ring 9 Wear and failure, resulting in the negative pressure chamber 3 can not form a negative pressure inside, the piston 8 will be quickly reset after pressing, the delay self-closing function is invalid; 3, the one-way sealing ring 9 is immersed in water for a long time, it is also easy to affect its sealing performance , thereby invalidating the valve.
