一、产品简介 Product description
ZDLP、ZDLM 智能型电子式电动精小型单座、套筒调节阀(简称智能型电子式精小型调节阀)是电动单元组合仪表中的执行单元。它接受来自调节仪表及计算机等单元的电信号或操作单元的手控信号，并根据此信号的大小来自动控制阀的开度，从而达到对温度、压力、液面、流量等的调节。
ZDLP, ZDLM intelligent electric fine small single seat, Sleeve regulating valve(referred to as the intelligent electronic precision small control valve)。Is an execution unit in the electric unit. It is accepted by the regulator And computer and other unit of the electrical signal Or operating unit of hand control signal, And according to the size of the signal to automatically control valve opening, So as to achieve the temperature, pressure, liquid level, flow and so on Regulation.
ZDLP、ZDLM 智能型电子式电动精小型单座、套筒调节阀适用于一般流体介质的工艺过程控制，可广泛用于发电、冶金、石油、化工、轻工业等工业部门。
ZDLP, ZDLM intelligent electric fine small single seat, Sleeve regulating valve Process control for general fluid medium, Can be widely used in power generation, metallurgy, petroleum, chemical, light industry and other industrial sectors.
二、产品结构 Product structure
ZDLP、ZDLM智能型电子式电动精小型单座调节阀由 3810L 系列智能型直行程电子式执行器和 JP 型低流阻直通单座阀组成。智能型电子式电动精小型套筒调节阀由 3810L 系列智能型直行程电子式电动执行器和 JM 型低流阻直通套筒阀组成。
ZDLP, ZDLM intelligent electric fine small single seat, Sleeve regulating valve 3810L series intelligent actuator for linear actuator JP type and low flow resistance through single seat valve. Intelligent electronic power precision small sleeve adjustment valve 3810L series intelligent electric actuator with linear actuator And JM type low flow resistance through sleeve valve.
控制器部分接受输入信号(DC4～20mA或 DC0～10V)和来自开度检测部分的开度信号相比较放大，向消除其差值的方向驱动并控制可逆电机。
Controller part accept input signal(DC4～20mA Or DC0～10V) And the degree of opening signal is amplified by the signal of the degree of opening, Direction drive to eliminate the difference And control the reversible motor.
可逆电机的旋转通过驱动皮带传给被动皮带轮，被动皮带轮和输出轴用梯形螺纹连接，被动轮的旋转使输出轴靠止转销限定向上或向下移动。输出轴的移动通过反馈机构的齿轮传动传给精密电位器，精密电位器的开度信号反馈给控制器部分，输入信号和开度信号偏差消除时控制器令电机停止转动。
The rotation of the reversible motor is transmitted to the passive belt pulley by the driving belt, Trapezoidal threaded connections for passive belt wheel and output shaft, The rotation of the passive wheel causes the output shaft to move up or down. The output shaft is transmitted through a feedback mechanism to a precision potentiometer, Open signal feedback to the controller part of the precision potentiometer, When the input signal and the signal deviation of the signal are eliminated, the motor stops rotating.
调节机构由阀体配用不同结构型式的阀盖(普通型和散热片型)形成两种调节机构，用于不同的温度范围。按公称压力可分为PN16 、40 、64、100 四种。
Regulatory agencies from the body with different structural types of valve cover(common type and heat sink type) Two kinds of adjustment mechanism, For different temperature ranges. According to the nominal pressure can be divided into PN16, 40, 64, four.
按阀芯结构可分为直线特性和等***比特性两种,单座阀与套筒阀主要由阀体、阀盖、阀杆、阀芯、套筒(套筒阀)、阀座等零件组成。见下图
According to the structure can be divided into linear characteristics And equal percentage characteristics of two kinds of, Single seat valve and sleeve valve Mainly by the valve body, valve cover, valve stem, valve core, sleeve (Tao Tongfa), valve seat and other components。See below
