Description

具泄压、减压的分段给水控制结构
本发明是有关一种具泄压、减压控制的阀体结构，特别是用于分段控制流体开、闭时，因水锤现象造成的瞬间水压，经泄压座、泄压阀及套合座的构造，并配合分段控制部的作用，即可有效控制瞬间管内高压冲击，致避免管路破裂。
现行高楼水流管路设计时，为避免管路在水流瞬间断流时造成管路破裂，一般都将出水口的管径制成较输水主干管小，以避免出水管瞬间断流时的水锤现象造成出水管线破裂，然而，此一设计不仅无法完全避免管路破裂，反而造成设计、施工上极大困扰，因而就有各种减压、泄压装置的出现。
但是，由目前所有已知的减压、泄压装置中，尚无任何可同时兼具泄、减压，且可分段控制水流、或为任意液态流体的构造，以致使用时需分别生产、分别装设，对产、销、使用三方面，都有相当程序的不便。
为此，发明人针对该些不理想处，研究改进，终于有本发明产生。
本发明的目的旨在提供一种可避免分段给水的高水压管路，于使用时因瞬间断流，致使管路破裂的结构。本发明的目的是这样实现的：其是于出水管末端设一压力控制部及一分段控制部，当分段控制部由打开状态进入闭合状态时，水流由套合座进水端的进水孔少量流入，相当时间后，压力控制部的泄压座适当侧设置的泄压孔，可将水由出水端排水，同时配合泄压阀与套合座的阻水作用，致压力控制部出水端的阻压力渐大于管内水压，即可完全断流排水，且兼具断流前泄压、减压作用功效。
依前述的此一具泄压、减压的分段给水控制结构，其压力控制部的套合座为可调整式构件，组装时可依水流压力大小而调整其适当压制力，以适应多种不同水压，为其另一目的。
至于本发明的详细构造、应用原理、作用与功效，则参照下列附图所作的说明，即可得到完全的了解：
图1为本发明一较佳具体实施例的局部剖示图。
图2为本发明一较佳具体实施的构造立体分解图。
图3为本发明一较佳具体实施例的动作图。
图4为本发明一较佳具体实施例的动作图。
图5为本发明一较佳具体实施例的动作图。
图6为本发明一较佳具体实施例的动作图。
图7为本发明一较佳具体实施例的动作图。
图8为本发明一较佳具体实施例的按压部分解图。
图1为本发明较佳具体实施例的构造局部示图，同时参看图2本发明构造立体分解图所示，本发明主要包括有：压力控制部1、分段控制部2，并配合管接头3、出水器具4、按压控制部5等所组成。其中，压力控制部1是由一泄压座11、一泄压阀12、一套合座13、二弹簧14、15及一垫圈16组成；泄压座11为罩形结构，其外端形成有牙端111，以螺设一推杆25的螺孔251，另端呈中空状的内孔112，座体外部近牙端111处包覆有软性(如橡胶)质材的塞部113，且适当处贯设有一个以上的泄压孔110，泄压阀12的柱状体中段适当处则形成一凸缘121，且皿状体的套合座13底部贯通一进水孔131，配合二弹簧14、15及一垫圈16构成压力控制部1；分段控制部2则由一齿轮座21、一导合齿轮22、一定位齿轮23、一弹簧24及一推杆25组成，其齿轮座21管体内适当处设有推杆座211及一导合齿部212，导合齿轮22及定位齿轮23，则可配合前述的导合齿部212，使结合的推杆25作适当的旋转分段升、降定位，以控制水流的进出开、闭；而按压控制部5则一按钮51、一结合元件52、一止水垫圈53、一推杆54，及一推抵件55所组成，配合管接头3、出水器具4(即本体)等构件，即可组合成一莲蓬头的泄压、减压分段给水控制的构造。需要说明的，本发明的此一具体实施例，仅为多种实施构造之一，其压力控制部1、分段控制部2，另可依需求而配合其他按压构件，而应用于水管出水控制、水龙头出水控制、液体断流控制......等结构。
请参看图3--图7所示，是本发明压力控制部1与分段控制部2的实施例动作示意图，并请参看图1、图8的实施例图示，由图中可看出当我们轻压按压控制部5按钮51时，推杆54向内抵顶推抵件55，经推抵件55下推分段控制部2的推杆25，配合紧迫结合在推杆25下端适当处的导合齿轮22、定位齿轮23啮合作动，由图3的闭合状态进入图4的打开状态，此时压力控制部1则如图5般，由分段控制部2的定位齿轮23作用，使与导合齿部212卡挚而定位不动，致使水流由泄压座11外部箭头所指般，流经齿轮座21管内空间后，由出水器具4导流出水以供使用。
若将按钮51再次轻按并推动分段控制部2，令定位齿轮23脱离导合齿部212的卡挚，则泄压座11会由图5、图6、图7般依序动作后，通过压力控制部1的泄压座11的塞部113，抵止于齿轮座21的口端，使与齿轮座21口端回复成闭合状态，此一瞬间断水动作，因为管路内的水流会产生水锤现象，致使泄压阀12因断水时瞬间较大的水压推力作用，即呈如图7的箭头所示般，使部份水流经泄压座11内部空间，并由其泄压孔110缓慢、且少量逐渐排流至齿轮座21的管内空间，至相当时间后，因断水后泄压座11外部的瞬间水压，逐渐减小至小于压力控制部1内弹簧14的弹力时，弹簧14会将泄压阀12下压，并抵紧塞住套合座13的进水孔131，即达成完全封闭止水，且使管内水压会达到适当的平衡，如此也可避免管路因高水压冲击作用，导致破裂的现象。
图8为本发明一实施例按压控制部5的元件分解立体图，另参看图1所示，当轻力按下按钮51时，按钮51会推抵结合元件52，令套有止水垫圈53的推杆54向出水器具4内设的推抵件55推压，通过推抵件55下推前述分段控制部2的推杆25向下作动，即可达成驱动压力控制部1的泄压座11与齿轮座21口端开、闭，达到控制水流开、关的结构。
综上所述，本发明的此一具泄压、减压的分段给水控制结构，确实具有产业上利用性、新颖性与进步性，且其压力控制部1及分段控制部2，经配合各种不同构造的按压控制部5后，另可使用于各种管路出水(可任何液体管路)、泄压、减压的功效，能改进现有技术不能同时兼具泄、减压功能，以致使用时需分别生产、装设的缺点。
