Precision casting internal thread globe valve
The opening and closing part of the precision casting internal is a gate. The movement direction of theinternal thread globe valve is perpendicular to the direction of the fluid. The precision casting internal thread globe valve can only be fully opened and closed, and cannot be adjusted or throttled. The internal thread globe valve has two sealing surfaces. The two sealing surfaces of the most commonly used mode internal thread globe valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2 ° 52 'when the medium temperature is not high. The internal thread globe valve of the wedge internal thread globe valve can be made as a whole, called a rigid gate; it can also be made as a internal thread globe valve that can produce a small amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle during processing. The board is called an elastic shutter. The stainless steel internal thread globe valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The representation method is: Z41H-16P.
