It is the most basic unit for valve assembly of the whole machine, and several parts make up the components of the valve (such as bonnet and disc components, etc.). The assembly process of several parts...
In the correct drainage scheme of the steam pipeline, we know the configuration of steam traps in main and branch pipelines. Contents: 1. Position of steam traps: close to the pipeline or close to the...
Leakage of the Valve Body and the Bonnet Reason: 1. The casting quality of iron castings is not high, and there are defects such as sand holes, loose structure and slag inclusion on the valve body...
1. The installation position of pneumatic control valves should be at a certain height from the ground, and there should be a certain space between the upper and lower parts of the valve to...
The casting material is integrally cast in a mold, and its stress distribution is uniform. There is no restriction on the compression direction. The forging is pressed by the force in the same direction,...
In the production process of offshore and onshore natural gas treatment facilities, the valves used are basically high-temperature and high-pressure valves and their main functions are to control the...
In the forging process of valves, there will occasionally be defects such as gas holes, porosity, and impurities, which affect the normal use of the castings, and are usually repaired by welding....
The commonly used materials for valve bodies are as follows: 1. Gray cast iron: it is suitable for low-pressure valves with working temperatures between -15℃ and +200℃ and nominal pressure...
Opening and closing over set pressure means that the equipment is opened or closed over its set pressure. In this case, the overload protection function of the safety valve loses, and the reasons...
2. A new type of structural design of the ultra-low temperature floating ball valve Given that there are disadvantages for the current common floating ball valve structure, a...
Abstract: A new type of structural design plan of the ultra-low temperature floating ball valve was proposed based on the structural analysis of the existing common ultra-low temperature floating...
