Abstract

The invention discloses a shaft-free and sleeve-free suspension type double-seat metal hard sealing check valve, and relates to the technical field of check valves, the shaft-free and sleeve-free suspension type double-seat metal hard sealing check valve comprises a valve body, a first flow guide body and a valve clack, and further comprises a connecting mechanism, a second flow guide body, a limiting mechanism and a supporting mechanism, the first flow guide body is installed in the valve body, and the connecting mechanism is installed in the first flow guide body; the second flow guide body comprises a flow guide plate, a connecting bolt, a valve seat and a connecting plate, the flow guide plate is installed in the valve body, one side of the flow guide plate is connected with one side of the connecting plate, a threaded hole is formed outside the connecting plate, the connecting bolt is installed in the threaded hole, and the valve seat is installed outside the flow guide plate; and four mounting grooves are formed in the outer surface of the connecting plate. According to the shaft-free and sleeve-free suspension type double-seat metal hard sealing check valve, the valve clack can be dynamically opened and closed along with the flow state of water, water hammers can be eliminated, meanwhile, valve closing noise is not generated, and the mute effect is achieved.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a shaftless and sleeveless suspension double-seat metal hard seal check valve. Background technique [0002] Shaftless and sleeveless suspension double-seat metal hard seal check valve is mainly composed of valve body, valve seat, valve disc, guide body, spring and other main components. The clear water medium of petrochemical and other systems should be installed at the outlet of the water pump or in other pipelines with non-return requirements to prevent the backflow of the medium from causing damage to the pump and pipeline system. [0003] The Chinese invention patent with the publication number CN112361040A discloses a check valve, which includes a valve body and a valve core assembly. The inner diameter of the flow part is smaller than the inner diameter of the outlet part and the inlet part; the valve core assembly includes a support piece, a guide cylinder, a plural...
