产品描述 Product Description

截止、节流、止回多功能阀完全替代传统管路中必须安装的截止阀、调节阀、止回阀三台阀门使用，平均体积小67%，重量轻62%，支出费用节省53%左右，是一种节能、节资、大量减少空间的更新换代新产品。

The multifunctional valves of cut-off, throttling, and check completely replace the three valves that must be installed in traditional pipelines, namely cut-off, regulating, and check valves. The average volume is 67% smaller, the weight is 62% lighter, and the expenditure is saved by about 53%. It is an energy-saving, cost saving, and space saving new product.

主要技术性能（Main technical feature）

产品特点  Product Features

1.截止阀功能：当进口管路停止供压或大修时，为确保阀后压力无泄漏，可实行截止功能，顺时针转动阀杆推动阀瓣向阀座关闭。Stop valve function: When the inlet pipeline stops supplying pressure or undergoes major repairs, to ensure that there is no leakage in the pressure behind the valve, a stop function can be implemented. Rotate the valve stem clockwise to push the valve disc towards the valve seat to close.

2.节流阀功能：为保证阀后达到设计要求的流量和压力，可实行流量调节功能，顺时针转动阀杆减少流量和压力，逆时针转动阀杆增大流量和压力，同时可按照阀杆上刻度和阀前阀后压力进行细调。Throttling valve function: To ensure that the designed flow and pressure are met after the valve, a flow adjustment function can be implemented. Rotate the valve stem clockwise to reduce flow and pressure, and counterclockwise to increase flow and pressure. At the same time, fine adjustments can be made according to the scale on the valve stem and the pressure before and after the valve.

3.止回阀功能：在临时停车或停压时，防止管路压力流体倒流损坏管路中设备或保证阀后压力，此时阀后还没有形成回流冲击力，本阀的弹簧早已推动阀瓣止回关闭，有效的控制止回时的水锤冲击。 Check valve function: During temporary shutdown or pressure shutdown, it prevents the backflow of pipeline pressure fluid from damaging the equipment in the pipeline or ensuring the pressure behind the valve. At this time, the backflow impact force has not yet formed behind the valve, and the spring of this valve has already pushed the valve disc to check and close, effectively controlling the water hammer impact during the check

4.直通式和角式安装交换功能：如直通式改为角式安装，只需拆下进口阀体和出口阀体连接螺栓，进口阀体转180度即可实现角式安装 Exchange function for straight through and angle installation: If the straight through type is changed to angle installation, simply remove the connecting bolts of the inlet and outlet valve bodies, and the inlet valve body can be rotated 180 degrees to achieve angle installation
