HC44X橡胶瓣逆止阀中英文说明书

1、HC44X橡胶瓣逆止门Check Valve说明书(Instructions)南通市力沛流体阀业有限公司Nantong Lipei Fluid Valves Co., Ltd.1、产品概述： 1. Product overview:橡胶瓣逆止阀主要由阀体、阀盖、阀瓣组成，其中橡胶瓣由钢板作承压件及强化尼龙 布做衬底，外层采用热硫化整体包胶技术制成，阀瓣开关寿命可达100万次。The rubber flap check valve is mainly composed of a valve body, a bonnet, and a flap. The rubber flap is made o

2、f a steel plate as a pressure-bearing member and a reinforced nylon cloth as a substrate. The outer layer is made of hot vulcanization overall encapsulation technology. Up to 1 m川ion times.该阀采用全流面积式，具有水头损失小，不易堆积杂物，维修简便等特性。The valve adopts the full flow area type, which has the characteristics of sma

3、ll head loss, no accumulation of debris, and easy maintenance.此阀由于关闭行程小，行程角度仅35。即可达到全关闭，关闭速度快。该阀主要适 用于给排水系统，可安装于水泵出口处，以防止倒流及水锤对泵的损害。该阀还可以安装 在蓄水池进出水管的旁通管上，以防止池水倒流至给水系统中。该止回阀一般适用于清静 介质，不宜用于含有固体颗粒和粘度较大的介质。Due to the small closing stroke of this valve, the stroke angle can be fully closed at only 35

4、6;, and the closing speed is fast. The valve is mainly suitable for water supply and drainage systems, and can be installed at the outlet of the water pump to prevent backflow and water hammer damage to the pump. The valve can also be installed on the bypass pipe of the inlet and outlet pipes of the

5、 reservoir to prevent the water from flowing back into the water supply system. The check valve is generally suitable for clean media, not suitable for media containing solid particles and high viscosity. 2'产品特点：2. Product features:1、阀座采用大倾斜角设计，阀瓣关闭行程小；1. The valve seat adopts a large inclinatio

6、n angle design, and the valve flap closing stroke is small;2、阀瓣采用热硫化整体包胶技术，使用寿命可达10。万次；2. The valve flap adopts thermal vulcanization integral encapsulation technology, and the service life can reach 1 million times;3、耐冲刷，密封性能好；3. Scour resistance and good sealing performance;4、产品结构简单、保养、维修方便。4. The

Precautions for installation1、橡胶瓣逆止阀一般情况采用水平卧式安装，必须保证阀轴一定在水平安置。1. The rubber flap check valve is generally installed horizontally and horizont

9、ally, and the valve shaft must be placed horizontally.2、在管线中不要使止回阀承受重量，大型的止回阀应独立可设置支架或基础，使之不首 管道系统产生的压力的影响。2. Do not allow the check valve to bear the weight in the pipeline. The largecheck valve should be independently set up with a bracket or foundation to avoid the influence of the pressure generated by the pipeline system.3、安装时注意介质流动的方向与阀体所标箭头方向一致，严禁反向安装。3. During installation, pay attention to the direction of the medium flow and the direction of the arrow marked on the valve body. Reverse installation i
