一、产品介绍

水力控制阀是一系列控制阀的总称，它较早生产于以色列、荷兰、丹麦、美国、加拿大等国，九十年代进入中国，本公司生产的水力控制阀系列，分别为遥控浮球阀、可调式减压阀、缓闭止回阀、流量控制阀、泄压/持压阀、电动阀、水泵控制阀、压差平衡阀、紧急关闭阀、雨淋阀、定水位阀等产品。并广泛用于建筑、消防、水厂、暖通、市政、钢铁、电力、石油、化工等系统的管网。

水力控制阀它是利用水力控制原理，利用上、下阀腔的压力差控制阀盘的运动，再通过旁通管路和各种不同构造的导阀起不同功能产生系列阀。
●本公司生产的水力控制阀2001年由上海市科委和建委鉴定荣获国内最先进产品，鉴定号2001-6133号。
●由上海市工程建设标准化办公室2002年委托本公司制定了上海市建筑产品推荐性应用图集
“SJ系列水力控制阀安装图”图集号2002沪S/T-104。

●由中国工程建设标准化协会2002年委托本公司制定了水力控制阀应用设计规程标准，标准号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、产品特点：PRODUCT FEATURES

●阀体采用全通道、流线型设计，流体阻力小、流量大；
●阀体、阀盖内外采用环氧树脂粉体涂装，可防止阀体、阀盖的腐蚀；
●采用国外可拆卸阀座的先进技术，结构巧妙，维修更换方便(无须整台阀门拆除)；
●在管路中可任意立式或卧式安装，其可靠性不变；
●阀体、阀盖、活塞缸连接处采用密封垫和密封环双重保护；
●活塞缸采用导流孔，适当增加阻尼，使活塞运动更加平穗、灵活；
●全不锈钢活塞缸、整体活塞、丁橡胶密封环，完全组合大大延长使用寿命。

● 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.
