Electric cast steel globe valve-J941H electric cast steel globe valve is suitable for the pipelines of various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, electric power industry with nominal pressure PN1.6~16MPa and working temperature -29~550℃. Cast steel globe valve-J941H electric cast steel globe valve is suitable for pipelines with various corrosive media, with good corrosion resistance and sufficient strength. It is suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with nominal pressure PN1.6~16MPa and working temperature -29~550℃. The driving methods are manual, gear transmission, electric, pneumatic, etc. It can be installed in any position of the pipeline, and the medium flows from bottom to top. The product is designed and manufactured according to the national standard GB12235, with reasonable structure, reliable sealing, excellent performance and beautiful appearance. The alloy steel globe valve is suitable for high temperature resistant steam and oil pipelines and has the characteristics of high temperature resistance. According to this movement of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable shut-off function, and because the change of the valve seat port is in direct proportion to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, this type of valve is very suitable for use as a shut-off or adjustment and throttling. According to the movement of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable shut-off function, and because the change of the valve seat port is in direct proportion to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, this type of valve is very suitable for use as a shut-off or adjustment and throttling. The so-called static state of welding globe valve is also called steady state. Generally, the downstream flow is adopted, and the medium flows upward from the bottom of the valve flap: when the nominal pressure PN≥20MPa, the reverse flow is generally adopted, and the medium flows downward from the top of the valve flap to increase the performance of the seal. When in use, the medium of the low-temperature stop valve can only flow in one direction, and the flow direction cannot be changed; the axis of the valve stem of the low-temperature stop valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, making this valve suitable for the cut-off or adjustment and throttling of the medium. After the cryogenic shut-off valve was applied to the test system, it failed to operate. After the valve was disassembled, it was found that the valve stem and the bonnet were bitten, and there were two deep scratches at the centerline symmetrical position of the valve stem surface, and there were also two corresponding positions on the lower flange of the matching bonnet. Scratches. After analysis, there are two reasons for the failure. The valve is placed horizontally and in an open state during storage. The valve stem and the valve disc form a cantilever beam structure. The cantilever is 147mm long and the cantilever weighs 418kg. Safety precautions for selecting electric shut-off valves: (1) The shut-off valve is suitable for small-diameter pipelines that need to adjust the flow rate, the plunger valve pressure and the accuracy requirements are not high, or the trap valve is frequently closed to intercept the water flow in the unidirectional flow pipe section. (2) Due to the relatively large resistance of the stop valve, the plug valve is relatively suitable for pipelines where the solenoid valve does not require strict flow resistance. (3) It is not suitable for the medium with high viscosity or with particles that are easy to settle in the diaphragm valve. The steam stop valve is suitable for pipelines in various working conditions such as petroleum, chemical fertilizers, and electric power industries with a nominal pressure of PN1.6~6.4MPa and a working temperature of -29~450℃ to cut off or connect the pipeline medium. The product structure is reasonable, the sealing is reliable, the performance is excellent, and the appearance is beautiful; the sealing surface is surfacing with Co-based hard alloy, which is wear-resistant, corrosion-resistant, anti-friction performance, and long service life; the valve stem is quenched and tempered and the surface is nitrided Anti-corrosion and anti-friction properties; double sealing.
