    • An amplifying pneumatic switch which is responsive to low pressure signals includes a first chamber for receiving an input signal from a first pneumatic pressure source at a first pressure. The first chamber includes a wall formed by a movable, highly resilient diaphragm. A diaphragm plate is disposed generally coextensive with the diaphragm and is responsive to diaphragm movement. A nozzle is coupled to a second source of pneumatic pressure and is sealable for generating a pneumatic output signal at a second pressure. A sealing mechanism including a lever and a plunger coact between the diaphragm and the nozzle for sealing the nozzle in response to the input signal. A spring is provided for biasing the diaphragm plate to a quiescent position in the absence of an input signal.

    • An adapter integrates a tail piece and connection for coupling to plumbing fittings utilizing a union nut or flange and provides a press-fit connection to the tail piece for installation in the system. The method of manufacturing the adapter comprises the steps of forming a flange on a section of conduit; placing a threaded union nut or mounting flange over the flange fitting; roll-forming an internal, concave annular recess into the section of conduit extending from the nut and inserting an O-ring into the recess for completing the adapter. The adapter can then be sealably attached to a plumbing fitting, such as a valve or the like, utilizing a conventional flat gasket between the flange of the adapter and the plumbing fitting. The installation is completed by inserting a conduit into the adapter to clear the O-ring and crimping the bead formed by the recess to complete the sealed connection.
    • 适配器集成尾部和连接件,用于使用联管螺母或法兰连接到管道配件,并提供与尾部件的压配合连接以安装在系统中。 制造适配器的方法包括以下步骤:在导管的一部分上形成凸缘; 将螺纹联接螺母或安装法兰放置在法兰接头上; 将内部凹入的环形凹部卷成形成从螺母延伸的导管部分,并将O形环插入凹槽中以完成适配器。 然后,适配器可以利用适配器的凸缘和管道配件之间的常规平垫圈将其密封地连接到诸如阀门等的管道配件上。 通过将导管插入适配器以清除O形圈并压接由凹槽形成的凸珠来完成密封连接来完成安装。

    • A differential pressure transmitter includes a housing, a first chamber within the housing for receiving an input pressure to be sensed and a second chamber for receiving a transmitter adapted to generate an electrical signal representative of the input pressure. The chambers are separated by a continuously formed, highly resilient diaphragm. A reaction member embodied as a resilient spring is disposed in the second chamber for sensing a position of the diaphragm resulting from the magnitude of the differential pressure thereacross. The reaction member has a magnetized structure mounted thereon which coacts with a Hall effect transducer embodied in the transmitter for detecting the relative position of the magnetized structure and therefore of the diaphragm and responsively generating an electrical signal. The signal may be utilized for positioning actuator controlled dampers within a VAV system duct.
    • 差压变送器包括壳体,壳体内的用于接收待感测的输入压力的第一室和用于接收适于产生代表输入压力的电信号的发射器的第二室。 这些腔室由连续形成的高弹性膜片隔开。 体现为弹性弹簧的反作用构件设置在第二腔室中,用于感测由于其上的差压的大小而产生的隔膜的位置。 反应构件具有安装在其上的磁化结构,其与实现在发射器中的霍尔效应换能器共同作用,用于检测磁化结构和隔膜的相对位置,并且响应地产生电信号。 信号可用于在VAV系统管道内定位致动器控制的阻尼器。
