What are the new trends in chemical valves? "Peaking and neutrality of carbon" is a profound transformation of a socio-economic system. With the dual carbon goal, the domestic...

You may think that a valve has a few parts, simple structure and average accuracy. However, high requirements are put forward for the core sealing parts of a valve. Moreover, a valve has complicated manufacturing...

3.2.2 The size of the wedge The wedge is made from WCB, which is the same as the valve body and is integrally casted (Figure 4). Calculate the thickness tB of the wedge, and get the...

The structure and working characteristics of sealing pairs of wedge gate valves with large diameters are discussed in this article. Structure of sealing pairs of wedge electric gate valves...

The working principle, structure, characteristics and applications of a self-sealing blind plate used in the process device of the ultra-high pressure valve hydraulic test bench are introduced...

A metal seated triple eccentric ball valve is a new product, which is used in high-temperature, high-pressure and process media with more demanding conditions. 1. Structure of three kinds...

After the overpressure phase, the maximum relief pressure B is reached; return to the re-seat pressure C after the opening and closing pressure difference phase. The safety valve with liquid...

A safety valve is a protection device for boilers, pressure vessels, and pressure pipelines. It is used to prevent the pressure in the pressure equipment from exceeding the designed allowable value, thereby...

Safety valves are important safety accessories for boilers, pressure vessels and other pressure equipment. Their operational reliability and performance are directly related to equipment and personal...

The long-distance pipeline is global. It is an energy supply line from the Arctic Circle to the equator, from the mountains to the seabed, from the plateau to the desert, passing through seismic zones,...

The pipeline has become the main method of energy transportation nowadays. The pipes and valves that emerged at the right moment have developed rapidly, which has greatly promoted...

Under normal circumstances, when the valve is shipped, blind plates are installed at the inlet and outlet of the valve to avoid dust entering from the inlet and outlet of the valve. This also prevents...
