[j961y high temperature and high pressure power station stop valve structure features]
1. The product is designed and manufactured in accordance with ansib16.34 and E101 standards, and can be used with imported equipment.
2. The middle chamber of the valve adopts the pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance. The two ends of the branch pipe are 4. The sealing surface of the valve disc and the valve seat is made of Stellite cobalt based hardfacing. The sealing surface is 6. The depth of the stuffing box of the valve cover is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable, and the switch is stable.
7. The valve has the upper sealing structure to ensure that the valve does not leak out through the valve stem when it is opened and operated.
8. The opening and closing of electric stop valve are controlled by electric device, which is equipped with special motor, reducer, torque control mechanism, field operation mechanism, manual and electric switching mechanism. In addition to local operation, remote operation can also be carried out.
