The spring-loaded regulator (1) has a main body (2) containing a chamber (3) leading to an inlet (4) via an inlet aperture (5). The inlet is connected to a pressurized main water pipe (6). The outlet (7) of the chamber is connected to a pipe network (8) for local water distribution. The regulator has a flow pressure regulating plate (9) arranged opposite the inlet hole (5). The diaphragm (10) is fixed on the plate (9) and forms a seal with the upper part (11) and the lower part (12) of the main body (2). The adjustment plate has a guide rod (14) extending downward therefrom to a guide (16) in the inlet aperture (5). The compression spring (21) acts at its lower end (22) on the top of the diaphragm (19). The upper end (23) of the spring abuts the spring drive member (24) at the end of the drive tube (25) of the servo device (26). The driving pipe is accommodated in a fixing pipe (27) of the servo device and is fixedly connected with the upper part (11) of the regulator main body (2). A lead screw (28) remote from the spring is journalled for axial alignment in the drive tube within the fixed tube. A motor (29) and a gearbox (30) are arranged to drive the lead screw. And the nut (31) is fixedly connected with the far end of the driving tube (25). Thus, the spring drive member may be advanced to further compress the spring or retracted to release compression. A piping system (8) of the local distribution network extends downstream of the outlet (7). A flow meter (32) and a pressure sensor (33) are adjacent to the outlet in the piping system. They are electronically connected to a controller (34). The remote pressure sensor (35) is also connected to the controller at the farthest point (36) of the piping system (8).
弹簧加载调节器(1)具有主体(2)，主体(2)包含腔室(3)，入口(4)经由入口孔(5)通向腔室。入口连接到加压总水管(6)。腔室的出口(7)连接到用于本地水分配的管道网络(8)。调节器具有与入口孔(5)相对设置的流量压力调节板(9)。隔膜(10)固定在板(9)上，与主体(2)的上部(11)和下部(12)形成密封。调节板具有从其向下延伸到入口孔(5)中的导引件(16)的导杆(14)。压缩弹簧(21)在其下端(22)作用在隔膜(19)的顶部。弹簧的上端(23)在伺服装置(26)的驱动管(25)的端部邻接弹簧驱动构件(24)。驱动管容纳在伺服装置的固定管(27)中，与调节器主体(2)的上部(11)固定连接。远离弹簧的丝杠(28)被轴颈连接，用于在固定管内的驱动管中进行轴向对齐。电机(29)和齿轮箱(30)布置成驱动丝杠。螺母(31)与驱动管(25)的远端固定连接。因此，弹簧驱动构件可以前进以进一步压缩弹簧或缩回以释放压缩。本地分配网络的管道系统(8)在出口(7)的下游延伸。流量计(32)和压力传感器(33)在管道系统中与出口相邻。它们以电子方式连接到控制器(34)。远程压力传感器(35)在管道系统(8)的最远点(36)处也连接到控制器。
