Problems solved by technology

Since the rubber O-ring is used as the dynamic seal between the eccentric shaft and the valve seat, the pressure resistance is low, so that the overall design pressure of the boiler is limited. The pressure should be less than 5Kgf / cm 3 , the sealing ring is prone to water leakage due to natural aging, mechanical wear, eccentric extrusion and other reasons during use

Abstract

Change valve includes valve seat, valve closure, and rotor axis fixed on axis hole of valve seat. Valve pocket possesses one water-in cavity and two water-out cavities. Disc shaped static valve plate made of ceramics possessing one circular hole in center and two curved through holes is positioned on end face of inlet in two water-out cavities. A seal gasket is set between end face of inlet and the said static valve plate. A movable valve plate made from ceramics possessing a curved through hole and a polygonal blind hole is positioned on the static valve plate. A bar in equilateral polygon shape is on front end of rotor axis. Holding piece between the movable valve plate and valve closure for supporting the movable valve plate, and compression spring is between the holding piece and the valve closure. Features are good performances of anti water leak, pressure resistance and durability.

Description

technical field [0001] The invention relates to a dual-purpose boiler waterway reversing valve for heating and hot water. Background technique [0002] At present, the dual-purpose boiler water reversing valve for heating and hot water includes: a valve seat with a valve cavity, a valve cover fixed at the opening of the valve cavity of the valve seat, an eccentric shaft fixed on the valve seat, the eccentric shaft and the valve seat A rubber O-ring is used for dynamic sealing between the valves. A spherical rubber plug is fixed at the end of the eccentric shaft. The valve seat has a water inlet and two water outlets connected to the valve cavity. The axis of the eccentric shaft is located in the middle of the inlet of the water outlet. When in use, the water inlet is connected to the boiler outlet, and the two water outlets are respectively connected to the inlet of the heating device and the inlet of the water supply device. By rotating the eccentric shaft, the spherical ru...
