概述 Overview
管力阀是我公司工程技术人员参照国内外同类型的先进产品进行设计。吸收微阻缓闭止回阀、液控止回蝶阀、多功能水利控制阀的基础上研制而成，是水泵控制阀的换代新产品。它兼具电动闸阀、电动蝶阀以及止回阀的功能，并通过快关和缓闭的动作来消除水锤危害，保护水泵及管网系统安全。该阀是当前国内外结构最新颖、性能最先进、运行最可靠的泵站新型控制设备，主要用于自动化给排水泵站的离心泵、冶金、石化、水利、市政、环保等行业供排水系统。
The pipe force valve is designed by our engineering technicians in reference to the advanced products of the same type at home and abroad. It is a new product of water pump control valve, which can be developed by absorbing micro - stop check valve, hydraulic control check valve and multi-function water control valve. It has the function of electric gate valve, electric butterfly valve and check valve, and eliminates water hammer damage by fast closing and closing motion, protecting water pump and network system safety. This valve is currently the most novel structure at home and abroad, performance, run the most advanced, most reliable pump station new control equipment, mainly used in automatic centrifugal pump of water supply and drainage pumping stations, metallurgical, petrochemical, water conservancy, municipal water supply and drainage system and environmental protection industry.

特点 Characteristic
1、安全可靠性高，具有速闭、缓闭以及吸能腔三种消除水锤措施。动作连锁，不会产生误动作。
2、无需人工操作控制。当水泵启闭，利用阀前、后介质压力差为驱动力，使阀门自动按水泵操作规程的要求动作。
3、无需专业调试。阀门动作不受液位高差和出水压力以及水泵流量变化的影响，适用范围广。
4、基本无需维修，寿命长；节能效果明显，流阻近似蝶阀。结构长度短，重量轻，安装及维修方便。
1. High safety and reliability, it has three kinds of water hammer measures, such as quick closing, slow closing and suction chamber. Action chain, no misoperation.
2. No manual operation control is needed. When the water pump is opened, the pressure difference between the valve and the post-medium is the driving force, and the valve is automatically operated according to the operation procedure of the pump.
3. No professional debugging. The valve action is not affected by the high difference of the liquid level and the discharge pressure and the change of water pump flow.
4. Minimum maintenance and long life; The energy saving effect is obvious, and the flow resistance is similar to the butterfly valve. Short structure, light weight, easy installation and maintenance.
