Innovation and development of marine valve technology
In recent years, with the continuous development of global trade and the increase of ship transportation, marine valves, as an important part of ships, are also constantly innovating and developing. The functions of marine valves include controlling the flow of liquids and gases inside the ship to ensure the safety and normal operation of the ship. Here are the latest news in the field of marine valves: 1. Application of intelligent technology: With the continuous advancement of intelligent technology, marine val
On May 17, the Yangtze River Delta Regional Pump and Valve Industry Innovation and Development Forum, hosted by the Yancheng City Industry and Information Technology Bureau and the Binhai County People's Government and undertaken by Jiangsu Binhai Economic Development Zone, was held in Binhai. Wu Qibiao, secretary of the Binhai County Party Committee and county magistrate, attended Forum and address. The event invited Ma Yushan, an academician of the Chinese Academy of Engineering, Wang Wei, a professor-level senior engineer of the Hefei General Machinery Research Institute, and more th

Since the ball valve usually uses rubber, nylon and PTFE as the material of the seat seal, its operating temperature is limited by the material of the seat seal. The cut-off function of the ball valve is accomplished by pressing the metal ball against the plastic valve seat under the action of the medium (floating ball valve). Under the action of a certain contact pressure, the valve seat sealing ring undergoes elastic-plastic deformation in local areas. This deformation can compensate for the manufacturing accuracy and surface roughness of the sphere and ensure t
What is a manual butterfly valve?
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open. The butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the va
The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 5°, and 2°52' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also
Finite Element Analysis and Presetting of Marine Butterfly Valves
In recent years, many companies have also put forward the problem of preset production of large-scale marine valves (such as Φ5350mm in diameter) according to their needs. However, according to the existing marine valve preset manuals and corresponding standards, there is still a lack of relevant large-diameter marine valve design data, and there is also a lack of preset experience for large-scale marine valves. Because of this, it is necessary to carry out careful and accurate calculation and analysis, and it is necessary to carry out deformation and force analy
The function and principle of marine stainless steel check valve
Stainless steel valve classification According to the performance characteristics and uses of the steel plate, it is divided into stainless steel plate, sulfuric acid-resistant stainless steel plate, pitting corrosion-resistant stainless steel plate, stress corrosion-resistant stainless steel plate, high-strength stainless steel plate, etc. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, free-cutting stai
Structural characteristics of marine valve
According to the structural characteristics of marine valves, marine valves can be divided into gate valves, globe valves (ball valves), check valves, safety valves, throttle valves, steam traps, etc. Marine gate valves are installed without directionality. The marine gate valve has the characteristics of small fluid resistance and wide applicable pressure and temperature range. The diameter shrinkage can reduce the size of the parts, the force required for opening and closing is correspondingly reduced, and at t
Detailed introduction of marine valve
Marine valves meet the environmental conditions of ships and are used to control the pressure, flow and flow direction of fluids in ship pipelines. Relevant industry certification required Requirements for marine valves: Resistance to salt spray (sea water) erosion; Minimal installation and operation space; Changes in position during use (to adapt to ship shak
What are the commonly used marine valve standards?
The standard of marine valves can have a significant impact on the quality of valve products and the efficiency and economy of pipeline installations. In many cases, it is of great help to marine valve users. Marine valve standards can generally be divided into basic standards, material standards, product standards, component standards, structural element standards, inspection standards, etc. The basic standard mainly includes signs, supply requirements, structural length, connection dimensions, appearance requir
