Abstract
The invention relates to the technical field of valves, in particular to a stop valve for refrigeration equipment. An inlet pipeline and an outlet pipeline are arranged inside a valve seat. A flange thread and a lock screw hole are formed in the upper end port of the valve seat. A valve clack is arranged inside the valve seat in a matched mode. A valve clack spacer and a pressure plate are arranged on the lower portion of the valve clack. The valve clack is in ball connection with a valve rod. The valve rod is in threaded connection with a valve deck. A packing spacer, a packing and a gland are arranged on the upper portion of the valve deck. A valve rod sealing ring is arranged inside the gland. The gland is in threaded connection with the upper end portion of the valve deck. A starting and closing part is arranged at the top end of the valve rod. The valve deck and the valve seat are in threaded connection. The valve deck is provided with a lock screw for locking. The stop valve for the refrigeration equipment is simple and reasonable in structural design, low in weight, low in cost, good in sealing performance, long in service life and resistant to alternate change of temperature.
