一、產品介紹

水力控制閥是一系列控制閥的總稱，它較早生產于以色列、荷蘭、丹麥、美國、加拿大等國，九十年代進入中國，本公司生產的水力控制閥系列，分別為遙控浮球閥、可調式減壓閥、緩閉止回閥、流量控制閥、泄壓/持壓閥、電動閥、水泵控制閥、壓差平衡閥、緊急關閉閥、雨淋閥、定水位閥等產品。并廣泛用于建筑、消防、水廠、暖通、市政、鋼鐵、電力、石油、化工等系統的管網。

水力控制閥它是利用水力控制原理，利用上、下閥腔的壓力差控制閥盤的運動，再通過旁通管路和各種不同構造的導閥起不同功能產生系列閥。
●本公司生產的水力控制閥2001年由上海市科委和建委鑒定榮獲國內最先進產品，鑒定號2001-6133號。
●由上海市工程建設標準化辦公室2002年委托本公司制定了上海市建筑產品推薦性應用圖集
“SJ系列水力控制閥安裝圖”圖集號2002滬S/T-104。

●由中國工程建設標準化協會2002年委托本公司制定了水力控制閥應用設計規程標準，標準號CEC8144：2002。

Hydraulic control valve is a general title of one series control valve, was earlier made in Israel, Holland, Demark, UAS, Canada etc. countries and led intoChina in 1900s. The hydraulic control valve series made in this Co.cover remote control floating valve, adjustable pressure reducing valve, slowly closed checkvalve, pressure discharge/sustaining valve, electric valve, water pump control valve, pressure differential balancing valve, emergent close valve, raining valve,water level fixing valve etc. products and are used for the pipe network of building, fire-fighting, water works, warming, steel & iron, electric power, petroleum,chemical industry etc. systems.

This valve makes a series valve formed by such a way as utilizing the hydraulic control principle and the pressure differential between both upper andlower valve cavities to control the disc’s movement and acting as different functions via the by-pass pipelines and the pilot valves of various different struc-tures.

●In 2001, the hydraulic control valve products made in this Co. were entitled as the most advanced products nationwide approved by both Scientific Commission and Construction Commission of Shanghai. The appraisal number: 2001-6133.
●In 2002, this Co. was entrusted by the office of Shanghai Engineering Construction Standardization to draw out SJ series hydraulic control valve installa-tion figure collection of the recommended application figure collection of Shanghai buildings’products, the figure collection number: 2002 HU S/T-104.
●In 2002, this Co. is entrusted by the Association of China Engineering Construction Standardization to draw out the standard for the application and de-sign rules of hydraulic control valves. The standard number: CECS144: 2002.
●In 2004, this Co. is entrusted by the office of China Engineering Construction Standardization to draw out the industrial standard for the hydraulic controlvalve products(coming soon).

二、產品特點：PRODUCT FEATURES

●閥體采用全通道、流線型設計，流體阻力小、流量大；
●閥體、閥蓋內外采用環氧樹脂粉體涂裝，可防止閥體、閥蓋的腐蝕；
●采用國外可拆卸閥座的先進技術，結構巧妙，維修更換方便(無須整臺閥門拆除)；
●在管路中可任意立式或臥式安裝，其可靠性不變；
●閥體、閥蓋、活塞缸連接處采用密封墊和密封環雙重保護；
●活塞缸采用導流孔，適當增加阻尼，使活塞運動更加平穗、靈活；
●全不銹鋼活塞缸、整體活塞、丁橡膠密封環，完全組合大大延長使用壽命。

● The body is full-channel and streamline designed, leaving small fluid resistance and a big flow;
● Both outside and inside of body and bonnet are coated with epoxy resin powder and can prevent them from corrosion;
● Use the advanced foreign know-how of removable seat ring, exquisite structure, easy repair and replacement (no need to remove the whole valve);
● Vertically or horizontally mountable in the pipeline with the reliability kept unchanged;
● A dual protection of sealing pad and sealing ring is used on the connections between body, bonnet and piston cylinder;
● For the piston cylinder, a flow-guide hole is set and appropriate damp is addad with it so as to have the piston movement more stable and flexible;
● The complete combination of full stainless steel piston cylinder, overall piston and NBR seal ring gets the duration greatly extended.
