The invention provides a balanced type multipurpose valve with
cut-off, non-return and adjusting functions. The balanced type multipurpose valve comprises a valve body, end flanges, valve seats, valve clacks, valve decks, supports and valve rods, wherein valve rod nuts are arranged in the supports, and operating handles are installed on outer surfaces of upper portions of the valve rod nuts. The valve is characterized in that each valve clack is formed by a
cut-off valve clack body and a non-return valve clack body, the lower portion of each valve rod penetrates through the corresponding valve
deck and is fixed to the top end of the corresponding
cut-off valve clack body in a hooked and combined mode, each non-return valve clack body is provided with a circular-cone-shaped head portion, the circular-cone-shaped head portion of each non-return valve clack body is matched with the lower portion of the corresponding
valve seat to be sealed, the
tail of each non-return valve clack body is inserted into the bottom of each cut-off valve clack body, the circular
conical surface of the bottom end of each cut-off valve clack body is matched with the upper portion of the corresponding
valve seat to be sealed, an axial balanced hole is formed in each cut-off valve clack body, L-shaped through holes enabling the balanced holes to be communicated with the outside of the valve body are formed in the tails of the non-return valve clack bodies, and inverted-L-shaped through holes enabling the balanced holes to be communicated with an inner cavity of the upper portion of the valve body are arranged in the bottoms of the valve rods. The cut-off, non-return and adjusting functions can be all achieved on the same valve, the valve has multiple purposes, pipeline operating space is saved, and production and manufacturing cost is reduced.
