产品描述 Product Description

进口管力阀(膜片式、活塞式)是水泵集手动控制阀、液控蝶阀、多功能水力控制阀阀与液力自动阀等控制阀门一体式控制阀。通过对阀门的流体设计，形成直线型流道，能耗低、运行稳，密封效果好，它兼具电动闸阀、电动蝶阀以及止回阀的功能，通过提高快关时间，能更好地消除水锤危害，保护水泵及管网系统安全。

The imported hydraulic valve (diaphragm type, piston type) is an integrated control valve for water pumps that integrates manual control valves, hydraulic butterfly valves, multifunctional hydraulic control valves, and hydraulic automatic valves. By designing the fluid of the valve, a linear flow channel is formed, which has low energy consumption, stable operation, and good sealing effect. It combines the functions of electric gate valve, electric butterfly valve, and check valve. By improving the fast closing time, it can better eliminate water hammer hazards and protect the safety of the water pump and pipeline system.

压力等级：PN10-PN25

规格尺寸：DN100～DN800

产品特点 Product Features

1.功能齐全：该阀具有防止回流、轻载启泵、消减水锤、自动控制、开度显示和远程监控等功能，完全满足大型自动化泵站的离心泵控制要求，可更好的替代多功能水泵控制阀和管力阀。

  Complete functions: the valve has the functions of preventing backflow, light load pump, reducing water hammer, automatic control, opening display and remote monitoring, which fully meet the centrifugal pump control requirements of large automatic pump station, and can better replace the multi-function pump control valve and pipe force valve.



2.安全可靠采用大、小双阀板结构，停泵时，偏心大阀板利用自身重力矩快速关闭，不受外界因素影响，安全可靠；即便小甩板出现故障
不能按照预定程序关闭，也不会发生水锤事故。

  Safe and reliable using large and small double valve plate structure. When the pump is stopped, the eccentric large valve plate is quickly closed with its own heavy torque, not affected by external factors, safe and reliable; even if the small swing plate fails
Can not be closed according to the scheduled procedures, and there will be no water hammer accident.



3.密封良好：大阀板采用金属硬密封结构，小阀板采用软硬组合密封技术，密封良好

 Good sealing: the large valve board adopts metal hard sealing structure, the small valve board adopts soft and hard combination sealing technology, good sealing

4.结构新颖采用双曲柄连杆机构；曲柄滑槽采用渐开线轨迹；阀杆采用单轴整体结构，强度高，刚性好；使用铸命长

  Novel structure adopts double crank connecting mechanism patented technology); crank chute adopts involute track (patent technology); valve shaft adopts uniaxial integral structure, with high strength and good rigidity; with long cast life.

5.结构简单：利用管网介质压力驱动阀门工作，无需外接动力，无电控设施，结构简单。

  Simple structure: use the pipe network medium pressure to drive the valve work, without external power, no electric control facilities, simple structure

6.维修方便：阀门控制系统元件均位于主阀外面，可不停机进行在线检修，维护方便。

  Convenient maintenance: The components of the valve control system are located outside the main valve, and the online maintenance is convenient.


7.节能降耗：阀体采用蝶式结构，阀板采用流线型设计，体积小，重量轻，节约材料；阻力小，能耗低，节能降耗效果明显。

   Energy saving and consumption reduction: valve body adopts butterfly structure, valve plate adopts streamlined design, small volume, light weight, material saving; small resistance, low energy consumption, energy saving and consumption reduction effect is obvious.

8.适应力强：既有膜片驱动机构（适合常温中低压工况），也有活塞式驱动机构（适合高温高压工况），还有污水型结构和回工压型结构，信号反馈型适合接入DC系统，远程监控阀门。


  Strong adaptability: both diaphragm drive mechanism (suitable for normal temperature and low pressure conditions), piston drive mechanism (suitable for high temperature and high pressure conditions), sewage structure and back pressure structure, signal feedback type suitable for access to DC system, remote monitoring valve.


9.调节精确：出口旁通管上设有双速调节阀，可精确调节开阀速度，并可大幅延长开阀时间。


   Accurate adjustment: the exit bypass pipe is equipped with a two-speed regulating valve (patented technology), which can accurately adjust the valve opening speed, and can greatly extend the valve opening time.
