Description

一种具有防爆装置的前置过滤器及其防爆方法 技术领域
本发明涉及净水设备技术领域，特别涉及一种具有防爆装置的前置过滤器及其防爆方法。
背景技术
在日常生活当中，为了提高用水质量，会通过过滤器对用水进行过滤后进行饮用，过滤器的滤芯在长时间的使用过程中，用水中的污垢会残留在滤芯的内壁上，日积月累使得滤芯本体变成了污物携带着，经滤芯过滤排出的用水内含有大量的细菌和病菌，人体在长时间饮用后，造成肠胃病变，严重影响了身体健康。有些家庭意识到上述用水问题，当滤芯使用一段时间后会对滤芯进行清洗或者直接更换滤芯，直接更换滤芯古人妥当，但是为生活增添了一笔开销。
为解决上述问题，申请人申请了专利号为ZL 201610644392.4专利名称为：一种具有自动清洗功能的净水装置及其控制方法的相关专利，但是该技术仍还存在着不足之处，即：净水器在低温的情况下会结冰产生高压或低温会使得水管(或者净水器)内的水结冰后膨胀进而使其胀裂、漏水或者在净水器的出水口遭遇堵塞时，净水器内部的高压同样也会使得水管(或者净水器)胀裂，这样会导致水资源和设备的严重损坏。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种具有防爆装置的前置过滤器及其防爆方法，旨在解决上述背景技术中出现的在低温或者高压的状态下胀裂水管或者净水器的缺陷。
本发明的技术方案是这样实现的：一种具有防爆装置的前置过滤器，包括过滤器本体，其特征在于：包括信息采集装置、控制器、与过滤器本体连通的防爆本体以及至少一个设于该防爆本体上的防爆孔，控制器与信息采集装置连接，当信息采集装置达到预定值后通过防爆孔将所述过滤器本体内的水量通过防爆孔排出，反之则关闭防爆孔。
优选为：所述的信息采集装置为温度传感器和压力传感器。
优选为：所述防爆本体包括与控制器连接的电动阀，当信息采集装置达到预定值后控制器控制电动阀连通防爆孔进行排水。
优选为：所述的防爆孔为能够将过滤器本体内的水量缓慢逐滴排出的微孔。
优选为：还包括设于过滤器本体进水端处的微漏检测装置；所述微漏检测装置包括与过滤器本体连通的管道、均位于管道内且顺着水流方向依次设置的叶轮以及与控制器电连接的电磁阀；所述管道内还设有用于检测叶轮旋转且与所述控制器电连接的感应器。
优选为：所述叶轮远离电磁阀的一侧设有流量扩大装置；所述流量扩大装置包括具有额定压力差的单向阀以及设于该单向阀上的细孔，经过该细孔的水喷设置叶轮上且使得叶轮旋转。
优选为：所述控制器内设有用于对叶轮进行旋转计时的微漏计时模块、用于对该微漏计时模块的计时值进行清零的清零模块、用于控制电磁阀的开启或者关闭的控制模块以及用于设置微漏计时模块的额定计时的输入模块，当信息采集装置的数据达到预定值后，微漏计时模块关闭。
此外本发明还提供一种适用上述具有防爆装置的前置过滤器的防爆方法，其具体步骤如下：
1)自动开启：压力传感器或/和温度传感器检测的数值达到预先设定值时，电动阀的阀体，旋转至防爆孔的位置，此时通过防爆孔来缓解过滤器本体内部水量带来的压力；
2)自动关闭：当压力传感器和温度传感器所检测的竖直均未达到预先设定值时，电动阀的阀体旋转至防爆孔关闭的状态。
本发明的有益效果是：当该过滤器与水管连接时，若出现过滤器内(或者水管内)的温度过低或是压力过高的情况，电动阀可将防爆孔调整至开启位置将过滤器内部(或者水管内)的水量部分排出，从而来解决过滤器或者水管胀裂而引起的水资源浪费的问题；其具体防爆原理为：众所周知，流动的水流的结冰难度要高于静态的水流的结冰难度，故在防爆孔开启时，可实现过滤器内以及水管内的水流出现流动的情况，从而来防止上述两者内部结冰，进而胀裂过滤器或者水管的情况；其次，在防爆孔开启时，可减少过滤器内与水管内的压力，从而进一步防止过滤器或者水管的胀裂；更详细的说：上述设置主要用于检测过滤器本体内部有无漏水情况，其具体为如下几个方面：(其一)、当过滤器在持续过滤水时(即：用户在用水时)，管道内部的水流进行流通并且带动叶轮旋转，当感应器检测到叶轮的旋转计时超过微漏计时模块上设置的额定时间时，控制器判断为漏水，并且控制电磁阀关闭；(其二)、当过滤器未过滤水时(即：用户停止用水时)，通过流量扩大装置使水流扩大并且使叶轮旋转，当微漏计时模块的检测值超过额定时间时，控制器判断为漏水，并且控制电磁阀关闭；需要说明的是：当微漏计时模块的检测值未达到额定时间时，则控制器判断为正常，进而通过清理模块对微漏计时模块的计时值进行清零；上述设置的目的：不仅可以检测过滤器有无漏水情况，并且还可保证防爆本体的稳定防爆性能。
本发明进一步设置为：所述的信息采集装置为温度传感器。
本发明进一步设置为：所述的信息采集装置为压力传感器。
