摘要： The method includes the following steps—introducing a low amplitude air pressure transient into the drainage and vent system of a building in order to propagate a pressure wave from a fitting (6) into a stack (1) and the network of the drainage system;—recording the passage of the transient by use of an air pressure transducer (7) located near the fitting (6) or introduction area of the transient;—establishing a pressure versus time signature recorded by the pressure transducer (7) and sending those signals to a central data acquisition system;—the pressure transient is propagated throughout the network at an acoustic velocity and is reflected by each and every pipe termination of the network so as to establish a characteristic reflection coefficient for each pipe termination; —the characteristic reflection coefficient is compared with testing results performed initially in a perfect network with no dry trap defects or leakages and in case a different signature is of the pressure trace is recorded, the point of diversion will be determined at the time at which the reflection from the altered pipe end termination arrives at the air pressure transducer so that the comparison of this direct trace with the stored defect free signature yields that time and, as the wave speed is known, the determination of the distance from the pressure transducer to the defective trap or seal.
摘要翻译：该方法包括以下步骤：将低振幅气压瞬变引入建筑物的排水和排气系统，以将压力波从配件（6）传播到堆（1）和排水系统的网络; - 通过使用位于配件（6）附近的空气压力传感器（7）或瞬态的引入区域来记录瞬态通过; - 建立由压力传感器（7）记录的压力与时间签名并发送这些信号到中央数据采集系统; - 压力瞬变以声速传播到整个网络，并被网络的每个管终端反射，以建立每个管终端的特征反射系数; 将特征反射系数与最初在没有干阱缺陷或泄漏的完美网络中执行的测试结果进行比较，并且如果记录了不同的签名是压力迹线，则转移点将在来自改变的管端终端的反射到达空气压力传感器，使得该直接迹线与存储的无缺陷签名的比较产生该时间，并且随着波速已知，确定从压力传感器到陷阱或密封有缺陷。

摘要： A drainage and ventilation system for a building is provided which includes two or more stacks which communicate fluid therein. The stacks are connected to a sewer for discharging liquid thereto, with at least one of the stacks having a discharge source for delivering liquid to a wet stack portion of that stack. A trap is positioned between the wet stack portion and the discharge source for inhibiting the passage of gas therethrough. The stacks are interconnected at an upper end thereof by a connecting member such as a connecting pipe or manifold, whereby air may be communicated between the stacks. An air admittance valve and a positive air pressure attenuation device are located above the connecting member, whereby air may be introduced into the stacks to compensate for entrained air moving with the liquid into the sewer, and air may be accumulated during increased pressure events, both helping to preserve trap seal integrity without releasing foul air into the surrounding environment.
摘要翻译：提供了一种用于建筑物的排水和通风系统，其包括两个或更多个在其中连通流体的堆叠。堆叠件连接到用于将液体排出的下水道，其中至少一个堆叠具有用于将液体输送到该堆叠的湿堆叠部分的排放源。陷阱位于湿堆叠部分和排放源之间，用于阻止气体通过其中。这些堆叠在其上端通过诸如连接管或歧管的连接构件互连，由此空气可以在堆叠之间连通。空气导纳阀和正空气压力衰减装置位于连接构件上方，由此空气可以被引入到堆叠中以补偿随液体进入下水道的夹带空气，并且在增加的压力事件期间可以积聚空气有助于保持陷阱密封完整性，而不会将恶臭空气释放到周围环境中。
