BSF静态平衡阀
BSF静态平衡阀
BSF static balancing valve
应用
可应用于空调、供热及生活热水系统中用来平衡末端及环路流量之用。具有关断功能，可代替截止阀；具有最大行程锁定功能，当系统调试后可将锁定功能开启，日后可关闭静态阀进行管路维护与检修，结束后可以直接将阀门恢复到设定好的最大行程处，避免二次调试，节约大量时间与成本。产品携带有测量接头，方便与测量设备的快速连接，节省调试时间。产品可应用于供水或回水管路。
Apply
It can be used to balance the end and loop flow in air conditioning, heating and domestic hot water systems. Has the relevant break function, can replace the stop valve; With maximum stroke locking function, the locking function can be turned on after system debugging, and the static valve can be closed for pipeline maintenance and overhaul in the future. After the end, the valve can be directly restored to the set maximum stroke, avoiding secondary debugging, saving a lot of time and cost. The product carries a measuring connector, which is convenient for quick connection with the measuring equipment and saves the debugging time. The product can be used in water supply or return pipeline.

测量精度
根据国际GB/T28636-2012要求，在阀门开度二50%时，误差不得大于士5%;10%开度50%时，误差不得大于士10%。上图为我公司产品的测量精度，完全优于国家标准的规定。故在产品选型时，建议设计流量下阀门开度大于50%为宜，同时为保证现场调试余量，阀门尽量设置在75%开度左右。
Measurement accuracy
According to the requirements of international GB/T28636-2012, when the valve opening is 50%, the error shall not be greater than 5%; 10% opening 50%, the error shall not be greater than 10%. The above figure shows the measurement accuracy of our products, which is completely better than the provisions of national standards. Therefore, in the product selection, it is recommended that the valve opening greater than 50% under the design flow rate is appropriate, and in order to ensure the on-site commissioning margin, the valve is set at about 75% as far as possible.
安装说明
安装前应确保系统内无杂物，请注意介质的流向与阀体上的流向标记一致，静态平衡阀一般安装于系统的回水管，当与动态压差平衡阀配套使用时，安装于供水管。通常与弯头或水泵连接时，需要保持一定的直管段安装距离；当与弯头连接时，遵循阀前5d,阀后2d原则；当与水泵连接时，遵循10d原则。
Installation instructions
Before installation, ensure that there is no debris in the system. Please note that the flow direction of the medium is consistent with the flow direction mark on the valve body. The static balance valve is generally installed in the system's return water pipe. Usually when connected with elbow or water pump, it is necessary to maintain a certain straight pipe section installation distance; When connected with the elbow, follow the principle of 5d in front of the valve and 2d behind the valve; When connected to the water pump, follow the 10d principle.
