Stainless steel internal thread vertical check valve
Due to the pressure of the medium at the inlet end of the pipeline, the valve opens or closes against the spring resistance. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core to the valve seat to close the valve, preventing the medium from flowing back, so it acts as a check. Stainless steel internal thread vertical check valves are widely used in chemical, liquefied petroleum gas, fluid and other industries.
Stainless steel internal thread vertical check valve
Product Introduction
Stainless steel internal thread check valve has high precision, beautiful appearance, small shape and spring device. Can be installed both vertically and horizontally. Mainly suitable for use in pipeline systems to prevent medium backflow. Silica sol precision cast stainless steel valve body. Introducing foreign advanced processing technology, the structure is reasonable and the shape is beautiful.
Working principle of stainless steel threaded vertical check valve
The stainless steel check valve is normally in a closed state. Due to the pressure of the medium at the inlet end of the pipeline, the valve overcomes the spring resistance and opens the valve. When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core to the valve seat to close the valve, preventing the medium from flowing back, so it acts as a check. The internal thread vertical check valve uses a spring to support the valve core, so it can be installed vertically or horizontally.
Product Features of Stainless Steel Internal Thread Vertical Check Valve
It has a short structure, small volume and light weight.
The valve disc closes quickly and the water hammer pressure is small.
The flow channel is smooth, the fluid resistance is small, the action is sensitive, and the sealing performance is good.
Easy to install, can be installed on pipelines in both horizontal and vertical directions.
The valve plate adopts the design of adding two torsion springs on the dual plate, which can make the valve plate close quickly by itself.
Due to the quick-closing effect, it can prevent the medium from flowing back and eliminate water hammer.
