1 产品技术规格 SPECIFICATIONS ZZCP 型自力式差压调节阀 Self-operated Differential Pressure Regulator ZZCP 型自力式差压调节阀, 是一种维持压力差为恒定值的一种节能型调节阀它可应用于燃烧系统, 发电机空压机轴封系统, 阀前 P 0.1Mpa 阀后 <10kpa, 连续控制其特点是设备运行中可进行设定值调整 ; 无填料, 动作灵敏 ; 能检测出微小的压力变化广泛应用于工业生产差压压力的自动控制中减压比大于 100 要用两级降压该系列分为 ZZCP-16B 常开 ( 差压增大时阀闭合 ) 和 ZZCP-16K 常闭 ( 差压增大时阀开启 ) 两种 ZZCP self-operated differential pressure regulator is one kind of energy-saving control valve keeping differential pressure as a constant. It is applicable for continuously controlling to burning system, generator and shaft seal system of air compressor(p1 0.1Mpa, P2<10kpa).It can set the value in running and feature no packing and adaptable. Inspect the slight variation in pressure with ZZCP. It is widely used in automatic control of differential pressure in industry producing. Use the secondary pressure reduction when the reduction ratio is more than 100. This series has ZZCP-16B normally open type (valve close for differential pressure increasing) and ZZCP-16K normally close type (valve open for differential pressure increasing). 标准规格 STANDARD SPECIFICATION 阀体 BODY 形式 Type 流体压力柱塞型阀芯 Fluid pressure contoured type 公称通径 Nominal size 公称压力 Pressure rating ANSI 150;PN16;JIS10K 连接型式 End connection 法兰式 Flange type ( JIS B JB/T ANSI B ;HG HG ) 阀内件材质 Trim materials 阀内件处理 Trim treatment 阀体及上阀盖 Body & Bonnet 各种材质组合及适用温度压力范围, 请参见表 1 As to the operating pressure-temperature limitation for each material, see Table 1 SCPH2/WCB, SCS13A/CF8, SCS14A/CF8M 各种材质的使用温度压力范围, 请参照表 1 As to the operating pressure-temperature limitation for each material, see Table 1 填料 Packing 无 Non 垫圈 Gasket 无石棉橡胶板 Non-asbestos rubber sheet 执行机构 ACTUATOR 类型 Type 薄膜式 Diaphragm type 膜片材质 Diaphragm material 规格 Specification 丁腈橡胶 NBR 用途 Purpose 调节 Adjust - 1 -

Chongqing Chuanyi Control Valve Co., Ltd., The action of ZZ VP-16K is pressure -to-open. After P1 throttling, P2 connects the diaphragm case (top) by pressure pipe.

4 Chongqing Chuanyi Control Valve Co., Ltd., The action of ZZ VP-16K is pressure -to-open. After P1 throttling, P2 connects the diaphragm case (top) by pressure pipe. It brings the down force at the effective area of bellow diaphragm, adding the spring first force (down). P2 increase or reduce, valve open wider or close smaller in the following to keep P2 as a constant. If P2 is not up to the setting value: such as P2 less than setting value, adjusting method: open the dustproof cover 1, turn bolt 2 counterclockwise to reduce spring pressure and make the setting value meeting the requirement. Otherwise, turn bolt 2 clockwise. 图 1 Fig.1 差压调节阀原理 Principle diagram 图 2 外形尺寸图 Fig.2 External dimensions - 4 -
