water power control valve series-1066vip威尼斯下载

product description

jlh three-in-one check valve has three functions: cut-off, non-return and throttling. it is mainly used for the outlet of the pump or other pipelines to prevent the backflow of the liquid, which can effectively prevent the water hammer impact and noise caused by the backflow of the ordinary check valve. it is suitable for water supply and drainage in general buildings, apartments and factories, cold and warm water treatment and boiler condensate water, and on the pump outlet of the secondary water supply pipeline to prevent the backflow of the medium in the pipeline caused by the stop of the pump.

scope of application

the three-in-one check valve is installed on the water supply and drainage of general buildings, apartments and factories, cold and warm water treatment, and boiler condensate water, and on the pump outlet of the secondary water supply pipeline to prevent the medium in the pipeline caused by the stop of the pump. backflow.

product features

1. with one valve, three functions can be successfully completed: non-water hammer check valve, gate valve, balance valve.

2. when the pump stops running, the spring force closes the valve disc first, thus preventing water hammer.

3. by adjusting the opening, the output of the pump can be adjusted.

4. equipped with an indicator, the opening degree of the valve can be confirmed with eyes.

5. the gasket is made of nitrile rubber, so it will not leak at all and can absorb the impact.

6. the spring is made of stainless steel, so it has strong corrosion resistance.

7. equipment materials and costs that can save water and reduce installation space.

8. because the shape and structure are highly streamlined, the pressure drop is very small.

9. because of its bypass function, it has the function of recovering the water in the pipeline on the outlet side, and supplementary water diversion when a vacuum occurs on the inlet side.

10. both horizontal pipes and vertical pipes can be installed.
