由上述技术方案可知, 本发明的热平衡机组的优点和积极效果在于: 本发明热平 衡机组中, 用户进水管、用户回水管、旁通管、和变频水泵等均集成在同一个箱体内, 这样热平衡机组就形成了一个整体模块, 不但方便运输, 而且在施工现场, 只需要将 箱体固定到合适的位置, 并将伸出箱体的用户进水管的进水管进水口、进水管出水口 和用户回水管的回水管进水口和回水管出水口分别与供热网络和终端用户的相应接 口连接好即可, 而无需在现场安装用户进水管、 用户回水管、 水泵等部件, 因此大幅 度降低了施工现场的劳动强度, 并减少了现场作业时间。 另外, 由于热平衡机组的各 零部件可以在工厂流水线上完成组装, 因此容易保证装配精度, 提高组装质量, 从而 减小了使用过程中出现安全事故的几率。 而且, 由于用户进水管的进水管进、 进水管 出水口的中心线位于同一直线上,用户回水管的回水管进水口和回水管出水口的中心 线位于同一直线上,这种布置方式能够与目前大部分的供热网络及用户端的预留端口 布置形式相匹配, 从而使本发明热平衡机组更好地整合到现有的供热网络中。 同时, 本发明中, 箱体能够阻挡灰尘等进入箱体内, 对变频水泵、 各种阀门等器件起到良好 的保护作用,从而改善了热平衡机组的运行环境,有利于延长热平衡机组的使用寿命。

下面将详细描述本发明的具体实施例。应当注意, 这里描述的实施例只用于举例 说明, 并不用于限制本发明。 实施例 1
如图 2、 图 3和图 4所示, 本发明热平衡机组第一实施例包括: 箱体 2、 用户进 水管 21、 用户回水管 22、 旁通管 23、 变频水泵 26以及控制柜 5。
箱体 2可以是正方体或者长方体形状, 包括底板、 两块侧板、 后面板、 顶板, 箱 体 2的前面安装有对开的检修门 20, 以方便本发明的热平衡机组在使用过程中进行 定期维护、 检修等工作。 在箱体 2的前面也可以固定前面板, 将检修门 20安装到前 面板上。箱体 2不限于正方体或长方体形状, 可以根据用户需求或者现场空间的具体 情况而任意设计箱体 2的形状。箱体 2对安装在其内的各零部件起到良好的防雨、 防 尘作用, 极大改善了本发明的热平衡机组的运行环境, 有利于延长热平衡机组的使用 寿命; 同时也有利于防止人为破坏热平衡机组的情况发生。 优选地, 本实施例中, 在 箱体 2上固定有安装座, 安装座包括分别焊接在底板下面两侧的两条角钢 3, 每条角 钢 3上设有用于供若干个连接螺栓 4穿过的螺栓孔,通过若干个连接螺栓 4可以将箱 体 2安装到供热网络中合适的位置。 当然箱体安装座不限于上述结构, 现有的能够实 现箱体固定的任何其他固定方式均适用于本发明。安装座的位置也不是必需在箱体 2 底板上, 还可以根据实际需要将安装座固定到箱体 2的左侧板、 右侧板、 顶板或后板 上, 例如当用户进水管 21、 用户回水管 22竖直安装时, 安装座设置到箱体 2的后板 上或者设置到左侧板、 右侧板上比较合适。
用户进水管 21、 用户回水管 22和旁通管 23组成了本发明热平衡机组第一实施 例的管路系统, 为了提高管路系统的保温效果, 尽量减少热量损失, 可以在用户进水 管 21、 用户回水管 22, 甚至旁通管 23外面包覆隔热保温层 (图中未示出) 。 用户进 水管 21、 用户回水管 22和旁通管 23均安装在箱体 2内, 可以由箱体 2内的多个支 架 30支撑。用户进水管 21的两端部分别为进水管进水口和进水管出水口, 该用户进 水管 21的进水管进水口和进水管出水口分别伸出箱体 2, 并且用户进水管 21的进水 管进水口和进水管出水口的中心线位于同一直线上; 用户回水管 22的两端部分别为 回水管进水口和回水管出水口, 该用户回水管 22的回水管进水口和回水管出水口分 别伸出箱体 2, 且用户回水管 22 的回水管进水口和回水管出水口的中心线位于同一
直线上, 用户进水管 21 的进水管进水口和进水管出水口所在的中心线可以与用户回 水管 22的回水管进水口和回水管出水口所在的中心线互相平行。 所以, 本发明热平 衡机组能与现有的大多数供热网络友好匹配, 安装方便。 在某些特别的场合下, 如供 热网络在某处空间受限而使连接端口位置发生变化,则可以通过外接连接管的方式实 现安装;也可以从本发明中的用户进水管 21或者用户回水管 22上预留的备用连接端 口实现安装。 用户进水管 21、 用户回水管 22在箱体 2以内部分的形状可以是多种多 样的, 但优选为直通管, 这样可以减小液体在管路中流动时的沿程损失, 从而减轻变 频水泵的负载, 有利于节能, 并方便精确控制温度。 另外, 用户进水管 21与用户回 水管 22可互相平行布置, 组装方便, 并且布局美观。 旁通管 23连通用户进水管 21 和用户回水管 22, 可以将部分从散热器流出的回水重新入到用户进水管 21内, 以调 节散热器的进水温度。 本实施例 1 中, 旁通管 23包括两段竖直部分和连接该两段竖 直部分的水平部分,水平部分上安装有单向阀 24,当单向阀 24选用重力式单向阀时, 其水平安装状态下可以减小开启压力, 当然单向阀 24并非必然水平安装。 当旁通管 23 是一个竖直的直通管时, 也可以使用重力式单向阀时, 只是开启压力要设定的稍 大些, 另外, 当旁通管 23是一个竖直的直通管时, 还可以使用弹簧式单向阀, 弹簧 式单向阀的开启压力不受其安装方向的影响。
本实施例 1 中, 用户进水管 21 的结构可以包括相互连通的第一用户进水管 211 和第二用户进水管 212, 二者之间安装变频水泵 26, 用户回水管 22的结构包括相互 连通的第一用户回水管 221和第二用户回水管 222, 二者由法兰连接在一起。 旁通管 23包括两个结构相同的第一 L形弯管 231和第二 L形弯管 232, 其中第一 L形弯管 231的竖直部分垂直固定于第一用户进水管 211上,第二 L形弯管 232的竖直部分垂 直固定于第一用户回水管 221上, 第一 L形弯管 231和第二 L形弯管 232的水平部 分相对布置, 且单向阀 24安装在第一 L形弯管 231和第二 L形弯管 232的水平部分 之间。第一 L形弯管 231与第一用户进水管 211可以一体成型, 或者通过其他焊接等 固定连接方式而形成第一部件, 同样,第二 L形弯管 232与第一用户回水管 221可以 形成第二部件, 当第一用户进水管 21 1和第一用户回水管 221的结构相同时, 所述的 第一部件和第二部件的结构也完全相同。如此设计的最大好处在于, 能够节省大量的 设计工作, 减少由设计工作带来的风险和劳动, 并适合于标准化大规模生产。
第一用户进水管 211上设有排污口 213, 检修时用于排出进、 出水管中的水, 或 者用于定期排污; 第一用户回水管 221上设有检测备用口 223, 以满足使用过程中检
测、 取样等需要。
变频水泵 26位于箱体 2内, 并安装在用户进水管 21上, 当然变频水泵 26也可 以安装到用户回水管 22或者旁通管 23上, 变频水泵 26用于给机组提供循环动力。 在某些对噪音有要求的场合, 可以选用静音型变频水泵。 为了使变频水泵 26产生的 热量及时散发出去, 延长变频水泵 26的使用寿命, 可以在箱体 2上设置给变频水泵 26散热的散热孔结构, 为了达到美观效果, 可以将散热孔结构设置在箱体 2的后面, 即设置到箱体 2的后面板上。
电动阀 25安装在用户回水管 22上, 可以邻近用户回水管 22的回水管出水口位 置。 当然电动阀 25 并不必然安装在用户回水管 22上, 其也可以安装在用户进水管 21, 只要电动阀 25与变频水泵 26安装在旁通管 23的不同侧 (如左侧、 右侧; 前侧、 后侧; 左侧、 后侧等) 均是可行的。 本实施例 1的热平衡机组中, 用户进水管 21的 进水管进水口或进水管出水口以及用户回水管 22的回水管进水口或回水管出水口中 的一个或者多个分别安装有截止阀, 用于供热网络中的连接管处没有截止阀情况; 当 然如果供热网络中的连接管上已安装有截止阀, 则本发明中的进、 出水管的各进、 出 水口上不必安装截止阀。
控制柜 5可拆卸地安装在箱体 2内上部空间内。控制柜 5内设有用于控制本发明 运行的控制系统, 该控制系统包括控制元件、设置在第一用户进水管 21 1上的第一温 度传感器 214、 第一压力传感器 215, 设置在第二用户进水管 212上并邻近进水管出 水口位置的第二温度传感器 216、 第二压力传感器 217, 设置在第一用户回水管 221 上的第三温度传感器 224、 第三压力传感器 225等。 电动阀 25连接于控制元件, 并 由控制元件控制其开度大小, 进而改变流量; 变频水泵 26连接于控制元件, 并由控 制元件控制其频率大小; 单向阀 24连接于控制元件, 并由控制元件控制其开启或者 关闭。 控制元件根据各个传感器所测得的数据对上述电动阀 25、 变频水泵 26及单向 阀 24进行控制, 以调节经旁通管 23、 用户进水管 21重新进入散热器的流量, 从而 调节散热器的进水温度, 以使用户终端取得适宜的温度。 实施例 2
如图 5和图 6所示, 本发明第二实施例的热平衡机组包括: 箱体 2、 用户进水管 21、 用户回水管 22、 旁通管 23、 变频水泵 26以及控制柜 5。 该第二实施例与第一实 施例的不同之处在于: 第一实施例中, 变频水泵 26安装在箱体 2内右下部分, 用户 进水管 21的进水管进水口和用户回水管 22的回水管出水口在箱体 2的左侧,用户进
水管 21的进水管出水口和用户回水管 22的回水管进水口在箱体 2的右侧,所以用户 端在热平衡机组的右侧; 而第二实施例中, 变频水泵 26安装在箱体 2内左下部分, 用户进水管 21的进水管进水口和用户回水管 22的回水管出水口在箱体 2的右侧,用 户进水管 21的进水管出水口和用户回水管 22的回水管进水口在箱体 2的左侧,所以 用户端在热平衡机组的左侧。 另外, 控制柜 5 (见图 5 ) 设置在箱体内的右上部空间 内。 该第二实施例中其他的与第一实施例相同的部分这里不再赘述。
实施例 3
如图 7所示, 本发明第三实施例的热平衡机组包括: 箱体 2、 用户进水管 21、 用 户回水管 22、 旁通管 23、 变频水泵 26以及控制柜 5。 该第三实施例与第二实施例的 不同之处在于: 用户进水管 21、 用户回水管 22的管径比较大, 变频水泵 26是大功 率的立式变频水泵, 因此该第三实施例的热平衡机组适合于负荷比较大的场合使用。 为了尽量减小整个热平衡机组的体积, 可以将用户进水管 21 的制成中部向前凸出的 形状, 变频水泵 26安装在该向前凸出的部分上, 以防止与用户回水管 22或者旁通管 23干涉; 另外, 该第三实施例的智能热平衡机中箱体 2 的体积较第二实施例中的箱 体 2体积大, 可以在前面开两扇检修门 20; 同时, 该第三实施例中的安装座包括 4 条角钢 3, 该 4条角钢 3分别焊接在底板下面四周, 并围成框形, 每条角钢 3上设有 用于供若干个连接螺栓穿过的螺栓孔,通过若干个连接螺栓可以将箱体 2安装到供热 网络中合适的位置。 该第三实施例中其他的与第二实施例相同的部分这里不再赘述。 实施例 4
如图 8所示, 本发明第四实施例的热平衡机组与第三实施例的区别在于: 用户进 水管 21为直管;旁通管 23的第一 L形弯管 231的位置相对于箱体 2底部的距离较短, 使得单向阀 24的安装位置比较低, 有利于降低本实施例的热平衡机组的重心位置, 从而更加稳定; 同时, 也有利于节约制造成本。
虽然已参照几个典型实施例描述了本发明, 但应当理解, 所用的术语是说明和示 例性、而非限制性的术语。 由于本发明能够以多种形式具体实施而不脱离发明的精神 或实质, 所以应当理解, 上述实施例不限于任何前述的细节, 而应在随附权利要求所 限定的精神和范围内广泛地解释,因此落入权利要求或其等效范围内的全部变化和改 型都应为随附权利要求所涵盖。 工业实用性
本发明热平衡机组中, 用户进水管、 用户回水管、 旁通管、 和变频水泵等均集成 在同一个箱体内, 这样热平衡机组就形成了一个整体模块, 不但方便运输, 而且在施 工现场, 只需要将箱体固定到合适的位置, 并将伸出箱体的用户进水管的进、 出水口 和用户回水管的进、 出水口分别与供热网络和终端用户的相应接口安装好即可, 而无 需在现场安装用户进水管、 用户回水管、 水泵等部件, 因此大幅度降低了施工现场的 劳动强度, 并减少了现场作业时间。 另外, 由于热平衡机组的各部件可以在工厂流水 线上完成组装, 因此容易保证组装质量, 减小了使用过程中出现安全事故的几率。 而 且, 由于用户进水管的进、 出水口的中心线位于同一直线上, 用户回水管的进、 出水 口的中心线位于同一直线上,这种布置方式能够与目前大部分的供热网络及用户端的 预留端口布置形式相匹配, 从而使本发明热平衡机组更好地整合到现有的供热网络 中。 同时, 本发明中, 箱体能够阻挡灰尘等进入箱体内, 对变频水泵、 各种阀门等起 到良好的保护作用, 改善了热平衡机组的运行环境, 有利于延长热平衡机组的使用寿 命。 因此, 本发明能够广泛地应用于供热系统等领域。
