Cast steel globe valve connected by valve cover bolts

Overview and Application

Cast steel globe valve connected by valve cover boltsThe valve cover is equipped with a cooling chamber, which can reduce the aging phenomenon caused by temperature and improve the compensation and sealing performance of the packing; The gland bolt adopts a flexible bolt design; Easy to disassemble. The valve seat is easy to replace and adopts a sealed welding method, which can reduce the deformation of the valve seat caused by external pressure; Its surface has undergone hardening treatment; Ensure good wear resistance and corrosion resistance. The bracket adopts a double reinforcement design with good rigidity. The valve stem is precision ground to ensure smooth sealing and operation, and the upper part of the valve stem is fixed with mechanical threads to improve toughness and enhance durability. Graphite sealing rings can maintain good sealing effect even under low pressure, high pressure, and even instantaneous high pressure and high temperature conditions.

Use a valve body guide rail structure to guide the valve disc and valve seat as coaxially as possible, with the guide rail length covering the entire stroke of the valve disc to ensure that the valve disc * enters the valve seat

Capable of "emergency discharge in case of valve partial opening" under high pressure differential conditions
