  •  Electric welding stop valve

Product overview

The electric welding stop valve j961h / Y (power station stop valve) is connected to the pipeline with welded structure, which is suitable for water and steam oil pipeline, and has the characteristics of high temperature resistance and high pressure resistance. It is mainly composed of welding stop valve and electric actuator. It can realize remote switch operation by accepting 380VAC voltage. The electric welding stop valve is suitable for various systems of petroleum, chemical, hydraulic and thermal power plants with nominal pressure of pn20-32mpa, P54 / 100v-p57 / 170V, and working temperature ≤ 540 ℃ (of which, the working temperature of p57 / 170V is 570 ℃), which can be used as a switch to cut off or connect the pipeline medium. The sealing surface is not easy to wear and scratch, good sealing performance, long service life, compact structure, good opening and closing performance, small height and convenient maintenance.
 
Performance advantages of electric welding stop valve:
 
1. The pressure self tightening sealing structure is adopted in the middle chamber of the valve, so the sealing performance is better. Both ends of the branch pipe are welded. Welding groove can be matched according to standard or user requirements.
2. The sealing surface of valve disc and valve seat is made of Stellite cobalt based cemented carbide, which is wear-resistant, high-temperature resistant, scratch resistant and has long service life.
3. The valve stem of high pressure welding power station stop valve has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment.
4. J961h / y electric stop valve cover stuffing box depth is reasonable, packing with corrosion inhibitor, sealing is reliable.
Design standard of electric welding stop valve:
 
Design and manufacture: JB / t3595 DL / T531
Structure length: jb2766 GB / t15188.1
Pressure temperature: JB / t3595
Test inspection: JB / t9092

Structure principle of electric welding stop valve:
 
Once the butt welded electric stop valve is in the open state, there will be no contact between the valve seat and the sealing surface of the valve disc, so the mechanical wear of the sealing surface is less. Because most of the valve seat and disc are easy to repair, or the whole valve does not need to be removed from the pipeline when replacing the sealing elements, so it is very suitable for the occasion where the valve and the pipeline are welded together Yes. The flow direction of the medium changes when passing through such valves, so the flow resistance of the power station stop valve is higher than that of other valves.
