概述 Overview
管力閥是我公司工程技術人員參照國內外同類型的產品進行設計。吸收微阻緩閉止回閥、液控止回蝶閥、多功能水利控制閥的基礎上研制而成，是水泵控制閥的換代新產品。它兼具電動閘閥、電動蝶閥以及止回閥的功能，并通過快關和緩閉的動作來消除水錘危害，保護水泵及管網系統安全。該閥是當前國內外結構穎、性能、運行的泵站新型控制設備，主要用于自動化給排水泵站的離心泵、冶金、石化、水利、市政、環保等行業供排水系統。
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.

特點 Characteristic
1、安全可靠性高，具有速閉、緩閉以及吸能腔三種消除水錘措施。動作連鎖，不會產生誤動作。
2、無需人工操作控制。當水泵啟閉，利用閥前、后介質壓力差為驅動力，使閥門自動按水泵操作規程的要求動作。
3、無需專業調試。閥門動作不受液位高差和出水壓力以及水泵流量變化的影響，適用范圍廣。
4、基本無需維修，壽命長；節能效果明顯，流阻近似蝶閥。結構長度短，重量輕，安裝及維修方便。
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.
