  What Is A Butterfly Valve? ​ Butterfly valve  is a simple structure, good sealing, long service life of the valve. Marine butterfly valve is widely used in the water supply system, sewage system and other fields. It is usually installed in the pipeline system of the ship to control the flow rate, pressure and direction of the fluid. ​ Marine butterfly valve  structure is mainly composed of valve body, valve plate and valve stem, wherein the valve plate can be rotated around the axis to open or close the valve. By rotating the stem, the opening degree of the valve plate can be adjusted to control the flow rate and pressure of the fluid. There are many types of  butterfly valves . Classified according to sealing form: forced seal butterfly valve, elastic seal butterfly valve, pressure seal butterfly valve,  automatic seal butterfly valve , etc.; According to the working pressure classification: vacuum butterfly valve, low pressure butterfly valve, medium pressur...

  What Is Gate Valve? Marine gate valve  is a special valve, mainly used to control the flow of liquid in the pipeline inside the ship. It is composed of a valve body, a seat, a disc, a stem and a handle, and has two modes of manual operation and electric operation. ​ Gate valves  work by driving the stem through a handle or a motor so that the disc moves up and down within the seat to open or close the valve. When the valve is closed, the medium flow in the pipeline can be cut off; When the valve is open, the medium can be allowed to flow through the valve. Marine gate valve   is characterized by simple structure, convenient operation, safety and reliability. Because the Marine gate valve needs to be switched on and off frequently in the ship's pipeline system, it needs to have good sealing performance and wear resistance. At the same time, because the Marine gate valve needs to be used at sea, it also needs to have good corrosion resistance and weather resistance. ...

  W hat Is A  Relief Valve ? Marine safety valve  is an  automatic valve , mainly used in boilers, pressure vessels and pipelines, to play the role of overpressure protection. Marine safety valve is one of the important equipment to ensure the safe operation of the ship, the correct selection and maintenance of safety valve is very helpful to the long-term stable operation of the ship. When the pressure inside the ship exceeds the set value, the spring of the Marine  safety valve  is squeezed, which opens the valve and releases some of the pressure. When the pressure returns to the normal range, the valve automatically closes, keeping the pressure inside the ship stable. There are many types of safety valves, which can be divided into various types according to different classification standards. For example, according to the structure can be divided into weight lever type, spring type and pulse type; According to the principle of action can be divided into...

  How Many Are The Classifications Of Marine Valves Marine valves  are Marine equipment used to control the pressure, flow and flow direction of the fluid in the ship pipeline to meet the environmental conditions of the ship. Valve is a fluid pipeline control device, its basic function is to connect or cut off the flow of the pipeline medium, change the flow of the medium, change the direction of the flow of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the pipeline equipment. There are many kinds of classification of  Marine valves , which can generally be classified according to some characteristics Classification by use:  Marine valves can be divided into cut-off valves, check valves, safety valves, regulating valves and diverter valves according to their use. These valves are used to connect or cut off the medium in the pipeline, prevent the reverse flow of the medium, ensure that the pressure in the pipeline or devic...
